jakman85andClaude Opus 5 6f61c9622d feat(ha): the CNI dials the control-plane VIP — kube-vip becomes a CNI prerequisite
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
OPERATOR DECISION 2026-09-06: "use the VIP as intended — a virtual address to reach
the cluster and provide fault tolerant HA. Without a change it will not work in HA."

THE DEFECT. Cilium's kube-proxy replacement dialled a SINGLE NODE. Re-confirmed live
before changing anything: all three prod cilium-agent pods carried
KUBERNETES_SERVICE_HOST=192.168.2.10 — k3s-prod-1's own address — while the kube-vip
VIP 192.168.2.9 was Running on all three nodes with a held lease. Lose prod-1 and the
CNI's control-plane path is dead on an "HA" cluster. clusters/prod's own comment said
the value must be the VIP and NOT .10, then called it "Not yet decided" — I treated
that stale comment as an open question when the evidence already settled it.

SPLIT, NOT REPOINT, because k3s_api_host had two consumers with opposite needs:
  k3s_api_host            unchanged — the FOUNDER's IP: the cold-bootstrap join
                          target and a tls-san. infra/tofu/outputs.tf GENERATES this
                          name, so renaming would ripple into tofu and the runbooks.
  k3s_apiserver_endpoint  NEW = {{ kube_vip_address }} — the HA address; what Cilium
                          consumes. Derived, not restated, so an environment overrides
                          ONE line and the VIP, the SAN and the CNI endpoint move
                          together. Prod needed no new override.

THE SECOND HAZARD, WHICH MY BRIEF DID NOT NAME and the agent found: pointing Cilium at
the VIP breaks a COLD bootstrap for the same reason the join would — site.yml ran
node-baseline -> k3s -> cilium, so Cilium would install against an address nothing
announced yet. That is the 2026-09-01 deadlock shape. Fixed by SEQUENCE, not value:
site.yml now imports kube-vip.yml BETWEEN k3s and cilium. It cannot go earlier
(kube-vip is a k3s auto-deploy manifest, so it needs a cluster) and it works there
because the DaemonSet is hostNetwork with KUBERNETES_SERVICE_HOST=127.0.0.1 — needing
neither CNI nor kube-proxy. roles/kube_vip gained a read-only `wait_for` on the VIP so
a cold run stops THERE with a named cause instead of surfacing as unreachable agents.

Also fixed a pre-existing bug that only mattered once this play joined site.yml: the
role's read-only interface probe ran without `check_mode: false`, so under --check it
was skipped and the assert fired with a misleading "set kube_vip_interface explicitly".

VERIFIED BY ME, not just reported:
  renders    dev K3S_API_HOST=192.168.1.49   prod=192.168.2.9  (each environment's VIP)
  cilium     template consumes k3s_apiserver_endpoint, not k3s_api_host
  cold join  still `--server https://{{ k3s_api_host }}:6443` — the founder
  order      site.yml: node-baseline -> k3s -> kube-vip -> cilium -> verify -> flux
  gate       full CI gate PASS
Agent-side, additionally: in-memory render of cilium-values.yaml.j2 per host showing
k8sServiceHost=the VIP with the join still on the founder; k3s_tls_sans renders
['.10','.9','127.0.0.1','.11','.12'] so NO cert reissue and NO k3s restart is involved
— .9 already answers under full CA verification; and --check --diff of kube-vip.yml
against prod reported 6 ok / 0 changed, i.e. the role edits change nothing about the
kube-vip prod already runs.

ha-control-plane-as-code 92 -> 112 assertions, turning two escalations into machine
checks: the Cilium template must use the endpoint var; the endpoint must derive from
kube_vip_address and k3s_api_host must not; per environment K3S_API_HOST must equal
that environment's VIP and be none of its node IPs (the [parity] contract, now
machine-checked rather than a comment); site.yml must order k3s -> kube-vip -> cilium.
Every new assertion mutation-tested and bites. One honest negative recorded: reverting
only the BASE default is not caught, because both overlays patch the key — the check
reads effective per-environment values, so the base default is unguarded.

APPLY ORDER, and this is the operator's step — nothing was applied:
  PROD FIRST, and it is the low-risk direction (prod is the broken one). Push and let
  Flux reconcile platform/cilium: the value change rolls the cilium-agent DaemonSet
  ONE NODE AT A TIME (maxUnavailable: 1 — the knob that bounded the 2026-09-01
  incident), it will not proceed past an unready pod, existing datapath survives an
  agent restart, and .9 is already live before the change lands.
  DEV SEPARATELY, operator present. Same mechanics but live dev agents dial
  192.168.1.50, and dev is mid-DNS-migration on dev-live. Do not fold it into that.
  ANSIBLE: nothing to run for either live cluster; the Ansible half matters only for a
  cold build. Remove the now-redundant standalone kube-vip.yml step from any runbook.

NEW NAMED GAP, unwritten: the L2 test cannot assert the running agents' live
KUBERNETES_SERVICE_HOST, which is the drift the L0 check cannot see. Recorded in that
test's gap list.

jakman85andClaude Opus 5 3ade1d440f fix(conformance): status.py read its own detection vocabulary as a TODO marker
`has_todo = "TODO" in text` — a bare whole-file substring. The new L0 check
`placeholder-guard-coupling/check.sh` ENUMERATES placeholder idioms as data
(`SEED = ["TBD","TODO","FIXME",...]`) because detecting them is its entire job, so
the harness classified a 32-assertion executable check as a TODO scaffold.

Consequence: R-STATE-03 — SAFETY-CRITICAL — reported `exec=1 scaffold=1` and
`not-derivable`, because status.py requires all of a requirement's tagged tests to
be proven. A safety requirement mis-reported by a substring match, plus a standing
--strict-coverage conflict that a previous engineer worked AROUND by rewording
prose instead of fixing the detector.

Replaced with two REDUNDANT structural signals, derived from the corpus (all 43
tests read), not invented:
  1. `# STATUS: scaffold` with the state as the FIRST token after `STATUS:`. Exactly
     3 tests declare it — onboarding-completeness, alerting, gitops-drift — and they
     are exactly the three real scaffolds. 19 others declare EXECUTABLE/RUNNABLE, so
     a loose `.*scaffold` would have matched prose.
  2. A TODO/FIXME marker CARRYING A MESSAGE in the body, where the body starts after
     the header comment block. A marker that is the ENTIRE content of a quoted
     literal is data, not a note, and is blanked before the scan. Every genuine
     scaffold marker in the corpus carries a message, so mid-body comments still count.

The line-322 intent is preserved exactly: each file is classified on its own
structure, either signal in either file sets scaffold + annotation_conflict, the
`executable: "true"` annotation is consulted only AFTER the body verdict, and
ambiguity still only downgrades. Vocabulary stays TODO/FIXME only — TBD/PLACEHOLDER
are excluded because two checks use them in real executable code.

NON-VACUITY, and the redundancy is the point: deleting the `# STATUS: scaffold` line
from all three real scaffolds still catches all three via the body rule. The decisive
perturbation is the reverse — the exact file that caused the bug, degraded to a
TODO-only body while KEEPING its `STATUS: EXECUTABLE` header, its idiom-naming header
prose and its `executable: "true"` annotation, is caught as a scaffold WITH the
annotation conflict raised. The annotation still cannot outrank the body.

TAGGING: the agent RECOMMENDED KEEPING `R-STATE-03` on placeholder-guard-coupling and
reversed my lean, on a ground I had missed and which is load-bearing:
ci/touched-requirements.sh maps `bootstrap/*` -> R-STATE-03, and `run.sh
--requirements` resolves R-IDs to test dirs THROUGH THESE LABELS. Removing the tag
would reopen the exact merge-gate hole a984442 closed. It also measured the
counterfactual — with the tag removed R-STATE-03 becomes `stale-proof`, not `proven`
— so the tag is not what holds PROVEN at zero.

R-STATE-03 before -> after: `exec=1 scaffold=1` / not-derivable + strict conflict, to
`exec=2 scaffold=0` / not-derivable with an ACCURATE reason (no ledger row for the L0
check; dr-restore is stale-proof).

LEDGER MECHANISM CONFIRMED CORRECT, not worked around. R-STATE-02's node-loss proof
(sha 57d4df8c) went stale because a984442 touched its evidence set — attributed
precisely to the single path `ci/touched-requirements.sh`. Fail-closed and by design.
Re-proving needs a real L3 run recorded from a clean tree at HEAD-or-later: a
live-cluster action.

OBSERVATION FOR LATER (not changed): scan_implementation counts
ci/touched-requirements.sh as implementation evidence for EVERY R-ID it names, so any
edit to that dispatch table invalidates every proof it mentions. Both current
stale/not-derivable verdicts trace to that one file. Fail-closed is the right
direction; whether a CI path-map should be implementation evidence is a separate call.

VERIFIED BY ME: `status.py --selftest` PASS (8 new assertions, both directions);
`--status --strict-coverage` exit 1 -> 0; `--layer l0` 11/11; the three
`STATUS: scaffold` files are exactly the three real scaffolds; kyverno L0 29/29 and
the full L0 stage green IN THE CONTAINER (the agent saw the stage skip on the host,
where the pinned kyverno CLI is absent). Full CI gate PASS. Counts unchanged:
coverage 48/51, scaffold-only 4, PROVEN 0 (stale 1).

jakman85andClaude Opus 5 cb1916f092 feat(conformance): cover R-PLAT-01, R-NET-04, R-SEC-03 — 88.2% -> 94.1%, and fix an unrecordable-proof defect
Coverage 45/51 -> 48/51, gaps 6 -> 3 (R-C2-01, R-C2-02, R-STATE-04), 0
safety-critical. --strict-coverage exit 0; run.sh --layer l0 11/11 PASS.

R-PLAT-01 — split L0 + L2, because "3 nodes with production-grade HA control
plane" is half authored and half observable.
  l0-static/ha-control-plane-as-code (92 assertions): environments DERIVED from
  the R-ENV-02 seam (never a hardcoded group name); k3s installed as `server` with
  no --datastore-endpoint/--disable-etcd anywhere; exactly ONE --cluster-init
  founder per environment; odd, quorum-capable server count with tolerance >= 1;
  tls-sans carry the VIP and every server IP; kube-vip leader-elected with
  cp_enable/svc_enable parsed from the template's OWN env pairs; each VIP outside
  its environment's LB pool and not a node IP.
  l2-behavioral/ha-control-plane: control-plane AND etcd role on every node,
  every node a REGISTERED etcd member, exactly 3 when the cluster says
  CLUSTER_ENV=prod, and an in-cluster Job curling /readyz through the VIP AND every
  server's own address — which proves the VIP fronts the API and that every server
  runs an apiserver, not one founder plus two joiners.

  An earlier draft probed those endpoints FROM THE RUNNER: that passes from prod's
  LAN and fails against dev (nodes behind the pfSense NAT), making the test a
  property of where it was launched. Hence the in-cluster Job.

R-NET-04 — what it adds over R-NET-05/07 is the PATH SET and the
totality/disjointness of the selecting rules, not another per-service check.
  l0-static/egress-paths-selected-by-rules (68 assertions): exactly two paths, the
  same closed set in schema + Kyverno policy + renderer; EXACTLY ONE
  CiliumEgressGatewayPolicy with a single selector matching only egress-class=vpn;
  nothing selects `internet` (absence of a rule IS the path); RFC1918 containment
  computed with `ipaddress` plus every address each overlay assigns itself; the
  tunnel default route and blackhole confined to table 51820 behind an ip rule that
  must carry a from/fwmark/iif selector; and the nft chain `policy accept` with
  every drop qualified — the internet-fails-OPEN direction that R-NET-06's L3 test
  does not assert.

R-SEC-03 — refuses the tautology "a test exists, therefore it is auditable".
  l0-static/auditability-proofs-producible (78 assertions) drives the real
  machinery: each of docs/07's five proofs must have an EXECUTABLE test at the layer
  the spec's wording demands (fault injection and DR drill => L3), taken from
  status.py's own verdict; run.sh --requirements must resolve and pass the gate's
  --require assertion; each proof declares a sentinel record_run.py can attribute,
  computed with record_run.parse_sentinels itself; and TWO FORGERIES are mounted
  against the real tools — a green JUnit whose log holds only a SKIP token, and a
  ledger row claiming `proven` at the root commit — which must come back not-proven
  and stale-proof. The five proofs are parsed from docs/07 when the spec is mounted,
  not hand-listed.

*** A REAL DEFECT FOUND AND FIXED, not asserted around. *** l2-behavioral's
default-deny, trusted-tls and gateway-ingress-reachable declared NO pass sentinel,
so record_run.py could never attribute a pass to them — the isolation and TLS audit
proofs were STRUCTURALLY UNRECORDABLE (landing as unknown-no-sentinel-declared,
and status.py requires all of a requirement's tests to be proven). Each now ends
with an additive terminal sentinel step reached only when every prior step passed.
Verified: all three carry it.

TWO HOLLOW DRAFT ASSERTIONS CAUGHT BY THE AGENT ITSELF, both the failure mode this
repo keeps hitting: (a) `svc_enable=false` matched a COMMENT in the kube-vip role
defaults, so flipping the template to true still passed — now parses the DaemonSet
template's env pairs; (b) the nft scoping check searched for the VALUE of a Jinja
variable while the template carries its NAME, matching nothing and passing
vacuously — templates are now rendered against role defaults first. 30 perturbations
across the three checks, all caught, plus 16 synthetic L2 perturbations via a
fake-kubectl shim.

R-C2-01/02 judged IMPLEMENTATION gaps, so no test was written: Homepage's
widgets.yaml carries only datetime and search, kubernetes.yaml is empty,
automountServiceAccountToken is false, and its NetworkPolicy allows DNS egress
only — no health source is even reachable. It has already drifted (crafty authors a
route with no tile). A test today would go red on both; it must ship WITH the
config fix.

VERIFIED: full CI gate PASS. Neither cluster mutated.

jakman85andClaude Opus 5 a984442cae harden: pin node timezone to UTC, and TEST the guard/value coupling that bit us
Two debt items, both about making a latent problem impossible rather than fixed.

=== 1. Node timezone pinned to Etc/UTC (node_baseline, `system` tag) ===

The prod nodes disagreed, measured from k3s's own etcd snapshot annotations:
prod-1/2 at -05:00 (Central), prod-3 at -04:00 (Eastern). Functionally harmless —
Kubernetes and etcd are UTC internally, and in UTC those snapshots are ~4 minutes
apart, which is correct staggering — but it makes cross-node log correlation
actively misleading, and this cluster has had two unplanned reboots in two days.

`Etc/UTC` chosen on repo convention, not just principle: catalog/plex.yaml records
"no other service in the repo sets a timezone ... so use the safe default" with
TZ: Etc/UTC, and apps/wave-0/plex.yaml matches (platform/crafty is America/Chicago
DELIBERATELY — a user-facing game schedule, not a log clock). Decisive extra fact:
THE THREE DEV NODES ARE ALREADY Etc/UTC, so this makes prod match dev rather than
inventing a convention. UTC also removes the class — no DST discontinuity, node
time == platform time.

New knob `node_baseline_timezone`, overridable per environment via group_vars (the
same seam as node_baseline_backports_kernel) but deliberately NOT restated there:
no environment needs to differ, and a second copy is a second thing to disagree.
Guarded by an assert in the role's existing BLOCKED style before the module runs.

`--check --diff --tags system -e k3s_hosts=k3s_prod` INDEPENDENTLY CONFIRMS the
offset evidence, and is the whole verification — the play was never run for real:
  k3s-prod-1: -"America/Chicago"  +"Etc/UTC"  changed
  k3s-prod-2: -"America/Chicago"  +"Etc/UTC"  changed
  k3s-prod-3: -"America/New_York" +"Etc/UTC"  changed
The same --check against DEV reports the task `ok` on all three — idempotence
demonstrated against live hosts, in check mode only. `--list-hosts` confirms
`-e k3s_hosts=k3s_prod` selects the three prod nodes (the diagnostic plays take
their OWN var; the wrong flag silently targets dev).

*** AUTHORED, NOT APPLIED. *** Applying it is a live-cluster action and was
deliberately left for the operator to schedule: prod's Longhorn had only just
finished resyncing after a node reboot, and changing a node's clock config during
storage recovery is not an unattended move.

`ansible-inventory --list` was NOT used anywhere — it prints DECRYPTED vault values
(the passphrase is mounted into the dev container) and has leaked the prod
become-password to a transcript once already.

=== 2. New L0 check `placeholder-guard-coupling` (R-ENV-02, R-STATE-03) ===

On 2026-09-05 the PM changed a placeholder in clusters/base/cluster-vars.yaml from
`TBD-PROD-S3-BACKUP-ENDPOINT` to `https://TBD-R2-ACCOUNT-ID...`. The guards in
bootstrap/standup.sh matched the glob `TBD-*` — a PREFIX. All three silently died,
and `resume` would have enabled velero on prod against a nonexistent hostname:
installs clean, reports healthy, no backups exist. Found by accident. A guard in
one file keyed on the SHAPE of a value in another file, with nothing tying them.

The check exercises the REAL predicate — it does not reimplement it. standup.sh is
not sourceable (top-level argv parsing hard-exits, cd, export, EXIT trap), so the
check extracts the predicate's own source lines and sources only those. Faithfulness
is pinned by: discovery of every `*_is_placeholder` (not a hardcoded name),
exactly-one-definition, "extracted block is a verbatim substring", a self-containment
gate, a canary (must refuse "", must accept a real URL), and a scan for a divergent
second copy. If the predicate grows a dependency the check FAILS LOUDLY and names
the remedy rather than degrading to testing a copy — the failure mode it exists for.

Both sides derive from real files: guarded knobs from a taint trace in standup.sh
(`x="$(cvar KEY)"` -> alias hop -> `*_is_placeholder "$x"`); values from base
cluster-vars plus each overlay's JSON6902 /data/KEY patches. The independent
detector is deliberately NOT the guard: seed idioms UNION the guard's own words with
glob anchors STRIPPED — so a prefix-anchored guard cannot pass, and deleting an arm
cannot make a value stop being placeholder-shaped.

Real tree: 32 assertions, 18 values through the extracted predicate, PASS.

NON-VACUITY VERIFIED BY ME, twice, on throwaway copies (the real repo and the
read-only spec repo untouched). My first perturbation tripped the self-containment
rail instead of the anchoring property, so I redid it shape-preserving — substring
globs -> prefix globs, nothing else — and it failed on exactly the right property,
naming mid-string and tail acceptances with the diagnosis "This is the 2026-09-05
failure exactly". Control: unperturbed copy exits 0.

=== 3. ci/touched-requirements.sh: bootstrap/ was UNMAPPED (found by the agent) ===

The path->requirement map had no `bootstrap/*` entry, so a change touching
standup.sh ALONGSIDE any already-mapped path scoped the L0 run to that other path's
requirements and silently excluded the new check — the one that exists to catch
exactly the 2026-09-05 class. A safety net with a hole where the incident was.
Mapped to R-STATE-03 R-GITOPS-01; verified the map now resolves bootstrap paths.

VERIFIED: full CI gate PASS. `run.sh --layer l0` 8/8 PASS including the new check.
Coverage unchanged at 45/51 (the new check tags existing requirements).

jakman85andClaude Opus 5 da3e9cc3f3 fix(kyverno): unblock CDI imports by SATISFYING the label requirement, not exempting it
Prod's UniFi VM has no disk. `DataVolume unifi/unifi-rootdisk` stuck in
ImportScheduled for hours, because Kyverno denied CDI's own generated pod:

  validate.kyverno.svc-fail denied Pod/unifi/importer-prime-<uid>
    require-auth-mode-label     (R-IDP-02)
    require-egress-class-label  (R-NET-05)

Both policies match any Pod in an `app-namespace: "true"` namespace with no
exclusion, and CDI generates `importer-*` itself — it cannot carry repo labels.
A COLD-START defect, not a prod quirk: dev's identical import Succeeded 9 days
ago, before the policies enforced, so dev has never exercised it and would hit it
on any rebuild. Fourth bug of this shape in two days.

MECHANISM: a MUTATE ClusterPolicy that ADDS
`egress-class: internet` + `auth-mode: none` (add-if-absent anchor) to Pods on
CREATE in app namespaces WHEN the requesting subject is ServiceAccount
`cdi/cdi-sa`. Both validate policies are untouched — no exclude, no exception,
`background: true` preserved on them.

Why mutate beats exempting: the requirement stays literally true ("every pod in an
app namespace declares both labels") and the values are HONEST — the importer does
pull over the default WAN path, and `internet` is the least-reach class (it does
not grant the VPN path); a transient worker pod with no UI genuinely is
`auth-mode: none`.

THE MATCH IS IDENTITY, NOT A NAME. `subjects: ServiceAccount cdi/cdi-sa` is the
AdmissionReview userInfo, taken from the real prod denial
(`system:serviceaccount:cdi:cdi-sa`, name importer-prime-…, op CREATE). A name
prefix is attacker-choosable; a requesting ServiceAccount is not — and the test
proves it, with a fixture `importer-prime-forged-by-an-app` that copies both the
name prefix AND CDI's labels and is still DENIED. Covers every CDI worker kind
(importer/uploader/cloner) without enumerating names that change per release.
Confirmed on prod that cdi-sa is the only cdi-namespace SA that can create pods.

REJECTED, and the first one is a trap worth recording:
  * PolicyException — the CRD EXISTS (v2/v2beta1, from the pre-applied bundle) but
    all controllers run `--enablePolicyException=false` (verified live on prod:
    admission, background and reports controllers all carry the flag). An exception
    would apply cleanly through Flux and be SILENTLY IGNORED. Enabling the gate is a
    cluster-wide capability change for no gain over the mutate.
  * `exclude` scoped to cdi-sa — sound identity, worse consequences: any userInfo
    match forces `background: false`, which would drop background scanning and
    policy-report coverage of R-NET-05/R-IDP-02 for ALL EXISTING PODS to fix one pod
    class. It also leaves the importer with no labels at all — the unlabelled
    fall-through that require-egress-class-label's own header calls a fail-open leak.
  * name-prefix / CDI-label matching — attacker-choosable, and proven walkable.

TWO-WAY PROOF, non-vacuous by construction — same resource, different requester,
opposite outcomes (verified by me, not just reported):
  userinfo cdi-sa   -> mutate pass, require-egress-class pass, require-auth-mode pass
  userinfo ordinary -> mutate SKIP,  require-egress-class FAIL, require-auth-mode FAIL
Kyverno L0 went 17 -> 29 tests passed, 0 failed. The mutate policy is deliberately
kept OUT of the existing tests/kyverno-test.yaml: that suite declares no userinfo,
and without userinfo the offline engine does not discriminate on subjects — it
mutates everything, which would have silently turned its negative rows into passes.

platform-config/kustomization.yaml is the live apply path for these ClusterPolicies;
without it the policy never reaches a cluster.

RESIDUAL TRADE-OFF, reversible by deleting one file: anything created by cdi-sa in
an app namespace now has these labels supplied rather than being rejected for not
declaring them — including a pod that is not a CDI worker. That identity already
holds `pods create/delete` cluster-wide via ClusterRole `cdi`, so it is not a new
capability; what changes is that for that one identity the declaration is assumed
rather than demanded. restrict-host-namespaces, the namespace default-deny baseline
and the CiliumNetworkPolicies all still apply.

FIRST resource-mutating policy on this cluster: kyverno-resource-mutating-webhook-cfg
holds 0 webhooks today; with autoUpdateWebhooks=true Kyverno registers
mutate.kyverno.svc-fail for Pods within seconds of this applying. Prod's
forceFailurePolicyIgnore=false makes it failurePolicy: Fail — same posture as the
validating webhook already in that path.

CDI retries importer creation on a loop, so the stuck import should proceed once
this lands. The detached prime-be3f9d1c-… 40 GiB scratch PVC is separate operator
cleanup; untouched, as is the DataVolume.

VERIFIED: full CI gate PASS. Nothing applied to any cluster.

jakman85andClaude Opus 5 04569abd78 docs(prod): node-maintenance runbook — a failed drain leaves a cordon that stops self-healing
Two unplanned node events (prod-3 ungraceful power-down; prod-2 memory upgrade)
produced one finding worth more than either incident.

A FAILED `kubectl drain` STILL CORDONS, and Longhorn's
`disable-scheduling-on-cordoned-node` is `true` — so a cordoned node gets no
replica scheduling. Observed after prod-2's reboot: ALL 17 VOLUMES sat
attached/degraded with prod-2 holding 2 of 18 replicas and ZERO rebuilds in
flight. Nothing was driving recovery, every pod was Running, and no alert fired.
`kubectl uncordon` started rebuilds immediately; converged 17/17 healthy in ~6
minutes (measured: 9→10→11→13→14→16→17 over 5 polls).

So uncordon is not tidying up — it is what re-enables storage redundancy. A green
pod list proves nothing about it.

DRAIN CANNOT COMPLETE ON THIS CLUSTER, and the two usual flags do not fix it.
`--ignore-daemonsets --delete-emptydir-data` clears the reported objections and
then hangs: all three instance-manager PDBs report ALLOWED DISRUPTIONS = 0 and
node-drain-policy is block-if-contains-last-replica. Requesting replica eviction
does not rescue it either — with 3 nodes and 3 replicas there is no fourth node to
move a replica to, so eviction can never complete. That is structural. Documented
options in preference order: just reboot (proven twice here; the 600s
replenishment interval means a quick reboot triggers no full rebuild); or scale
down the workloads holding engines on that node so the PDBs free up. Changing
node-drain-policy to always-allow is advised against at 3/3.

Also recorded: check the kube-vip leader before rebooting a server — it holds the
API VIP via a lease and is a DaemonSet, so a DRAIN does not move the VIP but a
REBOOT does, and kubectl blips for seconds. Plus a post-maintenance checklist
whose first item is verifying no cordon remains, and whose memory check exists
because this hardware silently strands RAM on the wrong kernel (§0b).

KNOWN, NOT FIXED: pod distribution does not rebalance — 52/10/50 after prod-2's
cordon+reboot. For the many single-replica apps here a spread constraint would
change nothing (one replica, one node). It self-corrects as pods restart. Recorded
because it concentrates failure: all three CNPG databases currently run on prod-1,
so losing that node takes Keycloak, Nextcloud and Semaphore together. The fix is
database HA (instances: 2), a resource decision the operator owns.

Header refreshed: phases A/B/C are done, 12/13 tiers, 112 pods, all three nodes at
full 32 GB after node 2's DIMM upgrade.

jakman85andClaude Opus 5 21e111b08c feat(devcontainer): dev.sh can target prod — and cannot silently target the wrong cluster
Operator report: dev.sh only reached the dev cluster. Line 72 hardcoded
`KUBECONFIG=${DEV_KUBECONFIG:-…/dev.kubeconfig}`, and the only escape was an
undocumented override whose NAME misleads — you set `DEV_KUBECONFIG` to a *prod*
path. infra/PHASE1-STATUS.md had recorded this as a "Known gap" for months.

WHY THIS WAS NOT A ONE-LINER. Both kubeconfigs name their context, cluster AND
user `default`. kubectl's merge keeps the FIRST occurrence of a duplicated name,
so the obvious `KUBECONFIG=dev.kubeconfig:prod.kubeconfig` resolves `default` to
DEV and `--context default` can never select prod — an operator or agent would
believe they were on prod and be issuing commands against the LIVE dev cluster
that runs the operator's platform. Same collision class as ~/.kube/config an hour
earlier, and worse here because agents run in this container.

Interface: `CLUSTER=dev|prod` as an env prefix, default **dev** (back-compat: every
existing invocation, CI job and habit keeps meaning dev).

    infra/devcontainer/dev.sh run kubectl get nodes                # dev
    CLUSTER=prod infra/devcontainer/dev.sh run kubectl get nodes   # prod

Its one weakness — `CLUSTER` can be inherited from an exported shell var — is
covered by a banner printed on EVERY invocation before the container starts:
`==> dev.sh: cluster=prod (kube context k3s-prod)`.

New infra/devcontainer/kubeconfig.sh generates a merged config with DISTINCT names
(contexts k3s-dev/k3s-prod, users k3s-*-admin), renaming structurally with `yq`
on .clusters[].name / .users[].name / .contexts[].{name,context.cluster,
context.user} before letting `kubectl config view --flatten` merge them. NOT sed —
sed renaming corrupted a config earlier today because cluster and user entries are
both `- name: default` at identical indent. Output is 0600 in the gitignored
.cache/, regenerated every run, and post-conditions assert the current context is
`k3s-<target>` and that NO context named `default` survived.

FAILS LOUDLY AT BOTH LAYERS, and never falls back to the other cluster — that
fallback is exactly how a prod command ends up hitting dev. Host-side refusal if
the requested cluster's kubeconfig is missing; in-container refusal likewise;
unknown CLUSTER exits 2. A missing source for the cluster you did NOT ask for is
tolerated (merges the other one only).

VERIFIED BY ME, independently of the agent — the two BASE_DOMAIN reads are the
unambiguous proof of which cluster was reached, since a node list is not:
  default (no selector)  -> home.keithjackson.dev        (DEV, unchanged)
  CLUSTER=prod           -> prod.home.keithjackson.dev   (PROD)
  contexts               -> k3s-dev, k3s-prod; NO `default` context survives
  exit codes             -> invalid CLUSTER=2, valid dev/prod=0
  standup.sh             -> `--kubeconfig` still wins over the new default
                            (preflight against prod: target confirmed 192.168.2.9)
  credentials            -> dev.kubeconfig and prod.kubeconfig byte-intact and each
                            still reaching 3 nodes after the agent's move-aside test
  git                    -> no kubeconfig committable; clusters.kubeconfig ignored
Full CI gate PASS.

NOT VERIFIED: `dev.sh build` and the interactive shell path (existing image reused,
no TTY available). The shell path shares run()'s code; only the TTY differs.

DEV_KUBECONFIG still wins verbatim, now with a deprecation warning. All existing
mounts are untouched: SOPS age keyring rw, ~/.ssh ro, ansible-vault-pass ro, spec
repo ro + SPEC_REPO, --network host, label=disable.

Closes the PHASE1-STATUS "Known gap".

jakman85andClaude Opus 5 fe45d0f5c5 feat(conformance): cover R-TLS-02, R-ENV-01, R-ENV-03 — 42/51 -> 45/51, and find a real gap
DECISIONS-LOG records Phase 7 being opened knowingly while the uncovered set
included R-ENV-01/02/03 — the very requirements prod provisioning serves. Two of
those three are now covered, plus R-TLS-02.

  tls-lifecycle-automated          R-TLS-02  L0 (in the merge gate)
  cert-lifecycle-automated         R-TLS-02  L2 (authored, NOT executed)
  dev-nodes-provisioned-as-code    R-ENV-01  L0
  prod-baremetal-not-dev-surface   R-ENV-03  L0

Coverage 42/51 (82.4%) -> 45/51 (88.2%), 6 gaps, 0 safety-critical. Remaining:
R-C2-01, R-C2-02, R-NET-04, R-PLAT-01, R-SEC-03, R-STATE-04. Verified through the
real runner: --layer l0 7/7 PASS, the three new ones 3/3 PASS, --strict-coverage
exit 0 with 0 label/annotation mismatches.

*** R-TLS-02 "REVOKED" IS NOT SATISFIED — A REAL GAP, NOT A TEST DEFECT. ***
The spec requires certificates be "issued, renewed, AND REVOKED without manual
steps", and docs/08 reads revocation as "removing/rotating a certificate is a
declarative change". That needs enableCertificateOwnerRef: true;
platform/cert-manager/helmrelease.yaml does not set it (chart default false).
Verified read-only on BOTH live clusters: gateway/wildcard-home-tls has ZERO
ownerReferences, so deleting the Certificate would leave the private key serving
indefinitely. The L2 test asserts the requirement AS WRITTEN and will fail until
this is decided. It was deliberately NOT softened — weakening a test to match the
implementation is how a suite stops meaning anything.

NOT FLIPPED UNATTENDED, and the reason is specific rather than caution: the
wildcard Certificate lives under ./platform, which runs prune: true. With owner
refs ON, any transient prune of that Certificate — exactly what happened to the
CDI StorageProfiles hours ago — would delete the SERVING TLS Secret for every
host, and reissuance is bounded by Let's Encrypt's duplicate-certificate limit
(5/week per identical name set), which could leave a cluster with no trusted cert
for a week. Security gap vs a plausible week-long TLS outage is an operator call.

NON-VACUITY DEMONSTRATED, which is the part that makes these worth having:
7/7 perturbations fail for R-TLS-02, 8/8 for R-ENV-01, 13/13 for R-ENV-03, and
each restored copy passes. Perturbations were applied to a throwaway copy; neither
this repo nor the read-only spec repo was modified.

TWO CHECKS INITIALLY PASSED WHEN PERTURBED and were rewritten — the exact
degrade-to-no-op failure this repo keeps hitting. The first draft asked "is this
file's DIRECTORY referenced by a kustomization", which a directory reference always
satisfies, and keyed Secrets by name alone, so external-dns's copy of
`cloudflare-api-token` satisfied cert-manager's reference. Now a recursive
kustomize resource-graph walk from each Flux path, and Secrets keyed by
(namespace, name). Both bite.

SECURITY NOTE, recorded because this project has already leaked a password once:
`ansible-inventory --list` PRINTS DECRYPTED VAULT VALUES — it emitted the prod
become-password to stdout during exploration, since the vault passphrase file is
mounted into the dev container. Both new checks use only --syntax-check and
--list-hosts, and say so in a comment. Confirmed no plaintext value reached disk:
vault.yml is still AES256-encrypted and the tree has no assigned value.

WHAT IS NOT PROVEN, per requirement: R-TLS-02 "revoked" (above), and issuance +
observed renewal await the unexecuted L2. R-ENV-01 cannot prove the running VMs
came from this module (needs OpenTofu state) — it proves the four lifecycle stages
exist as code and cover every dev node, and that the chain RESOLVES under real
ansible-playbook. R-ENV-03 cannot prove the HARDWARE (the K8s API exposes no
"am I virtual" fact; mini-PC/bare-metal is operator-attested) — it proves prod is
AUTHORED as 3 directly-reached nodes with no IaC creating them, sharing dev's
playbooks and roles, with no prod-only manifest, branch or role anywhere.

VERIFIED BY ME: coverage delta and the 3/3 L0 pass through the real runner; the
zero-ownerReferences finding on both clusters; that the new checks avoid
ansible-inventory; that no credential material reached disk. Full CI gate PASS.

jakman85andClaude Opus 5 8f9b2e4270 feat(backup): s3check proves a real round trip — and revives a guard I had killed
*** THE BUG, AND IT WAS MINE. *** The placeholder guards were `case "$s3" in
""|TBD-*)` — a PREFIX glob. Two commits earlier (32d6766) I changed the
placeholder from `TBD-PROD-S3-BACKUP-ENDPOINT` to
`https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com`, which does NOT start with
`TBD-`. Verified: fnmatch('https://TBD-R2-...', 'TBD-*') is False. All three
guards silently stopped matching, so **step_resume would have resumed velero on
prod straight onto a nonexistent hostname** — velero installs, reports healthy,
and no backup exists. That is precisely the failure the guard was written to
prevent, disarmed by a value change in a DIFFERENT file with nothing tying the
two together. Replaced with substring-matching s3_is_placeholder in preflight,
s3check and resume.

s3check rewritten from a reachability ping into a real proof. Per credential, from
a throwaway in-cluster pod (pod egress is the only egress that matters — the
workstation sits on a different network side and a host-side reading has already
misled this project once):
  1. the credential LOADS AND AUTHENTICATES in the exact shape its consumer reads
     — Velero's INI mounted from the `cloud` key, CNPG's discrete env keys;
  2. the bucket EXISTS and is LISTABLE under this environment's own prefix, via
     ListObjectsV2 — the op Velero's BSL sync and Barman's WAL scan actually use.
     ListBuckets deliberately avoided: a bucket-scoped R2 token may not grant it;
  3. PUT -> GET -> sha256+length compare -> DELETE -> confirm-gone. A HEAD would
     pass with a read-only token and with every write being rejected;
  4. the R2 checksum trap probed ON PURPOSE by repeating the PUT with checksums
     enabled, and named either way.
Buckets and prefixes are DERIVED (velero's from the authored HelmRelease via yq,
cnpg's parsed from CNPG_BACKUP_PATH), not restated.

Fails closed, with no "unknown, carrying on" arm left: no pod, unfinished pod,
empty log, missing/duplicate/malformed verdict, any failed assertion, a claimed
PASS with failures>0, an assertion count below the caller-computed minimum, an
OK-line count disagreeing with the claimed count, or a PASS from a pod that ended
Failed. Failures are classified by cause — no egress, NoSuchBucket,
InvalidAccessKeyId, AccessDenied (token not scoped to BOTH buckets),
InvalidArgument -> the checksum trap.

`amazon/aws-cli` pinned rather than `minio/mc`: mc lacks sed/awk (which already
broke one probe) AND cannot send checksum headers, so it cannot test for the trap.

TIER_ORDER now includes platform-config-cdi, between platform-config and the leaf
tiers. Without it `resume` returned success without ever waiting on the tier that
guarantees the CDI StorageProfiles — and apps-vms depends on them: unifi
provisions on longhorn-vm, where an unapplied profile means CDI infers RWO instead
of the authored RWX, permanently non-live-migratable.

CREDENTIALS: one key, four committed Secrets, two shapes — and NO manifest change
is needed, only encrypted values. platform/backup/set-r2-credentials.sh writes all
four with `sops set`, which encrypts IN PLACE, so no decrypted Secret ever exists
in the working tree to be committed by accident — strictly better than staging a
plaintext template. Prompts with `read -rs`, rejects anything outside the S3
credential charset (a paste that swallowed a newline authenticates nowhere), never
prints a value, and verifies by decrypting back and comparing fingerprints.
`--check` is read-only. The MinIO key is RETAINED — it is what reads the
pre-migration backups.

THE ACCOUNT ID IS ALREADY IN THE REPO: infra/tofu/backend.r2.hcl commits
https://7ce452a1b3d6c86daf2c020edcb82d37.r2.cloudflarestorage.com for the tofu
state bucket. If the backup buckets go in the same account, only the two token
values are needed. The placeholder is KEPT anyway — fail-closed beats convenience,
and the guard above just demonstrated why.
Corroborating the checksum fix independently: infra/tofu/backend.tf already carries
`region = "auto"` and `skip_s3_checksum = true # R2 rejects AWS trailing
(streaming) checksums`. This repo had learned both R2 facts for tofu state already.

VERSION FINDINGS, documented not measured against R2: plugin v1.14.2 documents
checksumAlgorithm defaulting to CRC32, so the authored "" is load-bearing;
Velero's kopia backend has NO checksum knob, so BSL metadata and PVC-data
compatibility are SEPARATE questions; and in the live CNPG 16.4 image,
boto3/botocore 1.35.60 is below the 1.36 line that turned on default request
checksums — so CNPG should be clear today, but barman-cloud exposes no escape
hatch, making a CNPG image bump an R2 re-verification event.

VERIFIED BY ME, independently of the agent: the dead-guard glob (fnmatch False);
the placeholder now refused on prod before any pod is created; a full round trip
against dev's MinIO — 7/7 assertions on BOTH credential paths, byte-identical,
pod Succeeded, nothing left behind, checksum trap correctly reported absent; all
four Secrets and the committed account id present. Full CI gate PASS.

STILL UNPROVEN AND SAID SO IN THE DOC: Velero-to-R2 (metadata or kopia data),
CNPG-barman-to-R2, and any restore from R2. R-STATE-03 is PROVEN MinIO-ONLY and
its ledger row predates this move. infra/BACKUP-R2.md §5 is the re-proof sequence
and it ends in a RESTORE, not an upload.

jakman85andClaude Opus 5 59ffbaf11a feat(conformance): L2 tests derive their environment from the cluster, not a literal
Six L2 behavioural tests embedded `home.keithjackson.dev`. They are test INPUTS,
not reconciled manifests, so postBuild substitution never touched them — correct
while dev held the apex, wrong the moment prod came up on
prod.home.keithjackson.dev, and blocking §9's "suite passes green against prod".

Each test now asks the cluster what it is, via a test-level chainsaw binding over
flux-system/cluster-vars — the SAME ConfigMap Flux renders the platform from, so
a test cannot disagree with the cluster it runs on:

  bindings:
    - name: baseDomain
      value: (x_k8s_get($client,'v1','ConfigMap','flux-system','cluster-vars').data.BASE_DOMAIN)

Chosen over a flag or env var because there is nothing to forget at run time, and
test-level scope covers every step (step outputs/bindings are step-scoped).

THE APEX WAS NOT THE ONLY LEAK. dns-exposure and dns-internal-resolution also
hardcoded DEV'S Cilium LB range 192.168.1.53-.60; prod's is 192.168.2.20-.30, so
both were wrong for prod regardless of hostname. Replaced with assertions on the
OBSERVED value — the DNS answer must equal that cluster's GATEWAY_VIP, and the
public record must equal the LB IP the Service was actually assigned — which is
strictly STRONGER than the old range check as well as environment-independent.
sso-forward-auth held the literal only in prose (it talks over Service DNS).

PROVEN, NOT ASSERTED — and the positive control is the important half:
  * expressions extracted verbatim from the tracked files resolve to the correct,
    DIFFERENT values per cluster (dev home.keithjackson.dev / 192.168.1.53,
    prod prod.home.keithjackson.dev / 192.168.2.20);
  * the same assert with the HARDCODED apex passes on dev and FAILS on prod
    ("Invalid value: *.prod.home... Expected: *.home..."), so the harness is
    provably not blind — that is exactly the drift removed;
  * chainsaw lint VALID on all six; run.sh --lint clean over the whole tree.

END-TO-END L2 RUN AGAINST LIVE DEV: `dns-exposure` PASSED (42.6s) — the binding
produced conformance-dns.home.keithjackson.dev, external-dns published it, and the
probe Job asserted the record against the assigned LB IP. This is the first time
one of these tests has been executed since parameterization, and it exercises the
full path rather than just the binding.

FINDING FROM THAT RUN, worth recording: the test's teardown is ASYNCHRONOUS. It
reports PASS as soon as chainsaw deletes the namespace, but the Cloudflare record
is reaped later by external-dns's own --interval=1m sync. A zone query immediately
after PASS still showed conformance-dns.home.keithjackson.dev plus its owner=default
TXT registry entry. Harmless here, but it means a green dns-exposure does NOT prove
cleanup happened, and if external-dns were suspended the record would persist
silently. Verified separately that it clears.

conformance/incluster/rbac.yaml: its cluster-wide `get configmaps` is now
LOAD-BEARING for these bindings — narrowing it to the test namespace breaks five
tests. Commented so it is not "tidied" later.

l3-fault-injection/dr-restore: its KNOWN-GAPS block said off-host is unproven
because the MinIO shares a Proxmox host with dev's VMs. Still true as run, so the
text now says both — that the R2 move (32d6766) is what closes it, that this test's
pass is against MinIO, and that the ledger row proving R-STATE-03 PREDATES the move,
so off-host DR cannot be claimed until the drill is re-run against R2.

NOT VERIFIED, plainly: no full L2 suite run against prod, so "green against prod"
remains unproven — what is proven is that the tests now derive the CORRECT
expectation for whichever cluster they are pointed at. Whether prod SATISFIES them
(split-horizon, LE wildcard, Grafana's issuer) is untested.

VERIFIED: full CI gate PASS. flux-postbuild-substitution 260 assertions,
render-golden 10/10.

jakman85andClaude Opus 5 765ad032db fix(gitops): CDI cold-start deadlock repaired IN THE GRAPH, not by a pre-apply
`platform-config` applied the CDI CR *and* cdi-storageprofiles.yaml in ONE pass.
StorageProfile's CRD does not exist until cdi-operator reconciles that CR, and
Flux server-side dry-runs every object before applying any — so the unknown kind
aborted the tier, the CR was never applied, the CRD was never created, and the
tier could NEVER converge. Observed on prod: cdi-operator Available 12h, no CDI
CR, no storageprofiles CRD, every downstream tier blocked.

The profiles now live in their own tier ./platform-config-cdi with
dependsOn: platform-config and wait: true. Because dependsOn is REVISION-gated
and platform-config runs wait: true, the CDI CR must be applied AND healthy —
exactly the event that creates the CRD — before the profiles are applied. Cold
clusters order themselves. `standup.sh crds` is retained as a fallback for
clusters already stuck, and because it is idempotent.

THE GENERALISABLE RULE (recorded in clusters/README.md): a CR whose CRD is
created by a CONTROLLER AT RUNTIME is second-order and needs its own pass.
cdi-operator.yaml registers exactly ONE CRD (cdis.cdi.kubevirt.io); storageprofiles,
datavolumes, datasources and dataimportcrons appear only after it reconciles the
CDI CR. An audit found StorageProfile is the only second-order kind in
platform-config — KubeVirt, CDI, KeycloakRealmImport, CNPG Cluster,
VolumeSnapshotClass, ClusterIssuer, PrometheusRule, ServiceMonitor and the Cilium
L2 CRs all have their CRD in git or in a chart.

Moving the CDI CR up into `platform` was rejected: that would put CDI's health on
the tier the CNI gates and everything waits on — the mistake the oauth2-proxy and
headlamp splits exist to undo.

apps-vms gains dependsOn: platform-config-cdi. LOAD-BEARING, not cosmetic:
apps/vms/unifi/20-datavolume.yaml provisions on storageClassName: longhorn-vm and
its comment claimed platform-config guaranteed the profiles — which this move
would have silently falsified.

THE PRUNE TRANSIENT, MEASURED RATHER THAN ASSUMED. platform-config has
prune: true, so it deletes both profiles once, CDI recreates them with empty spec,
and the new tier re-applies the overrides ~30-60s later. Compared our override
against CDI's unaided inference for the same Longhorn provisioner on dev:
  longhorn-vm (we override)     spec RWX/Block  -> status ReadWriteMany/Block
  longhorn-static (no override) spec unset      -> status ReadWriteOnce/Block
Both infer cloneStrategy: snapshot. So cloneStrategy is NOT at risk; accessModes
IS — unaided CDI gives RWO. A DataVolume provisioned on longhorn-vm inside the
window would be stamped RWO/Block and be PERMANENTLY non-live-migratable. Flux can
no longer cause it (apps-vms gates on the new tier); a human must not do it by hand.
Corroborating evidence that the recreate happens at all: dev has 5 StorageClasses
and 5 StorageProfiles, three with fluxOwner=NONE, spec unset and status populated
— CDI creating and inferring them with no Flux involvement.

MERGE PRECONDITION: `flux get kustomization platform-config` must be Ready on the
target first. If it is not, the profiles are pruned and sit at CDI defaults until
it recovers — and prod was in that state hours earlier. Fallback is the two-step
the Cilium move used (merge with prune: false, verify the ownership label moved,
restore prune: true).

substituteFrom: cluster-vars is declared even though the manifest has no ${TOKEN},
deliberately: conformance/tests/l0-static/flux-postbuild-substitution only audits
paths whose Kustomization declares it, so omitting it would move the file OUT of
the audited set — a blind spot for a future literal-token ship. Gate confirms it
stayed in (path=./platform-config-cdi files=2 defined=0 hazards=0). No SOPS
decryption stanza: the moved file is two plain CRs, so no overlay change was needed.

VERIFIED INDEPENDENTLY OF THE AGENT: platform-config renders 0 StorageProfile
while keeping the CDI and KubeVirt CRs; platform-config-cdi renders exactly the
two profiles; the graph is byte-identical across dev and prod with apps-vms
carrying both edges and no cycle. Full CI gate PASS.

KNOWN FOLLOW-UP: bootstrap/standup.sh TIER_ORDER does not yet include
platform-config-cdi, so `resume` will not wait on it. Another agent holds that
file; the PM will add it.

jakman85andClaude Opus 5 32d67660a6 feat(backup): move off-cluster DR to Cloudflare R2 (operator decision 2026-09-05)
"That's where backups will go for the time being until a better on-prem backup
solution is created." Two reasons beyond the (negligible) cost:

  1. Prod CANNOT reach the on-Proxmox MinIO. Prod is on the SOHO network
     192.168.2.0/24 — pfSense's WAN — while that MinIO sits inside pfSense's LAN.
     Measured from a pod inside prod: connection timed out after 15s. R2 needs no
     firewall change.
  2. That MinIO runs on the SAME Proxmox host as dev's VMs, so dev's
     "off-cluster" backup shared a physical failure domain with dev — one host
     loss took the cluster AND its backups. R2 is genuinely off-site.

COST, measured rather than estimated (read straight out of the buckets):
  velero  4.0 GiB / 6,264 objects  (7d retention; 8.65 GB live -> kopia dedup)
  cnpg    211 MiB / 1,755 objects  (keycloak 66Mi/331, nextcloud 87Mi/1329,
                                    semaphore 58Mi/95; ~7d of a 30d window)
Both clusters project to ~13-15 GiB and ~30k writes/month => pennies on R2, and
free egress means restore REHEARSALS cost nothing, so R-STATE-03 has no financial
disincentive to stay proven. Wasabi/Hetzner are 50-200x worse here purely because
of 1 TB minimums; Glacier tiers are a trap (90-day minimum billing against a
7-day Velero retention plus early-delete fees on 30-day WAL pruning).

*** THE R2 GOTCHA, WIRED UP FRONT: checksumAlgorithm: "" ***
velero-plugin-for-aws v1.14.2 bundles an AWS SDK that sends
x-amz-sdk-checksum-algorithm / x-amz-checksum-crc32 on every PUT. R2 REJECTS
those with HTTP 400 InvalidArgument, so every backup and every kopia blob upload
would fail. Set unconditionally — MinIO ignores it, so it needs no fork.

`region` was hardcoded us-east-1 inside the Velero HelmRelease: correct-by-
accident for MinIO (which ignores it) and WRONG for R2 (which demands exactly
`auto`). Now the S3_BACKUP_REGION knob.

PREFIXES ARE NOW SYMMETRIC (dev/prod), reversing the reasoning from two commits
ago. While the target was MinIO, dev HAD to keep the bucket root or it would
orphan the backups its proven restore depends on. R2 starts BOTH clusters on an
empty bucket, so there is no history to orphan — and leaving the bucket root
unused means a misrendered prefix lands somewhere obviously wrong instead of
silently colliding with a real environment.

NEITHER OVERLAY PINS THE ENDPOINT ANY MORE — a deliberate reversal of this
repo's "prod must never inherit base" rule. That rule exists because base
defaults are dev's LAN addresses; R2 is a single environment-INDEPENDENT endpoint,
so under R-ENV-02 it belongs in base, and two copies of one URL is a rotation
waiting to drift. Isolation comes from the path knobs, not the URL. Caught while
verifying: dev's overlay DID still pin MinIO, so dev would have taken the new
`dev` prefix while writing to the old endpoint — orphaning its MinIO backups for
no benefit. That is why the endpoint and the prefixes must move in ONE commit.

*** MERGING THIS RESETS DEV'S PITR WINDOW. *** Dev's R2 prefix starts empty:
Velero writes a fresh kopia repo, CNPG takes new base backups, the 30-day Barman
window rebuilds from zero. The MinIO copy is NOT deleted and stays restorable by
pointing the endpoint back. Do not merge while dev's proven restore is the only
recovery path you rely on.

STILL BLOCKED ON THE OPERATOR: the endpoint is the loud placeholder
https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com. Creating the R2 buckets and
an API token needs Cloudflare account access I do not have (the token in this
repo is Zone:DNS scoped). Velero+R2 and CNPG-barman+R2 are also UNPROVEN here and
must be verified by an actual backup AND restore, not just an upload.

VERIFIED: full CI gate PASS. Rendered both overlays — dev dev/s3://cnpg/dev,
prod prod/s3://cnpg/prod, region auto, one shared endpoint.

jakman85andClaude Opus 5 9063e53ce2 docs(prod): prod verified end-to-end through the real resolver — dnsmasq profile installed
Operator installed infra/workstation/dnsmasq/install.sh. Verified afterwards:

RESOLUTION (live NetworkManager dnsmasq, `getent hosts`):
  prod.home / gitea.prod / keycloak.prod / grafana.prod -> 192.168.2.20
  unifi.prod -> 192.168.2.21     crafty-mc.prod -> 192.168.2.22
  gitea.home / home.keithjackson.dev -> 192.168.2.50   DEV, UNCHANGED

HTTPS with NO --resolve override and NO -k, all landing on 192.168.2.20:
  apex 200 · gitea 200 · headlamp 200 · semaphore 200
  keycloak 302 (login) · grafana 302 (SSO) · nextcloud 302 · pihole 302

CERTIFICATE, confirmed by SNI — this is the check that actually settles the
earlier confusion, because the resolver bug made dev's cert look like a broken
prod cert:
  subject CN=*.prod.home.keithjackson.dev
  issuer  C=US, O=Let's Encrypt, CN=YR1   (LE production)
  SAN     *.prod.home.keithjackson.dev, prod.home.keithjackson.dev
  valid   2026-09-05 .. 2026-12-04
Dev checked in the same pass still serves CN=*.home.keithjackson.dev.

Also noted so it is not misread as a fault: `curl --cert-status` reports
"(91) No OCSP response received" because Let's Encrypt retired OCSP responders
in 2025 — there is nothing to staple. The plain requests validated normally.

Prod is now reachable and trusted from the workstation by name. Outstanding items
are unchanged: MinIO routing (prod is on pfSense's WAN), the apex flip being the
same event as the legacy-prod 443 cutover, and delivering the backup-tenancy
commits to prod via a c8c1d29-based branch.

jakman85andClaude Opus 5 6d62aca0d2 feat(workstation): prod dnsmasq profile — and CORRECT the topology I had wrong
OPERATOR CORRECTION (2026-09-05). I had been calling the resolver that shadows
prod "a pfSense override" throughout this repo. Both halves of that were wrong:

  - It is the WORKSTATION'S OWN dnsmasq, not pfSense. The live resolver is the
    one NetworkManager spawns (dns=dnsmasq, --conf-dir=/etc/NetworkManager/
    dnsmasq.d); the standalone dnsmasq.service is INACTIVE, so /etc/dnsmasq.d is
    dormant. The dev profile's `address=/.home.keithjackson.dev/192.168.2.50`
    matches the domain AND EVERY SUBDOMAIN, so it also swallowed the whole new
    prod.home.* tree and answered it with dev's address.
  - The k3s prod cluster is NOT behind pfSense. It sits on the SOHO router
    network 192.168.2.0/24, which is pfSense's WAN; pfSense CONTAINS the dev LAN
    192.168.1.0/24. This workstation is on 192.168.2.0/24 too, which is why the
    rules below use prod's real VIPs and need no NAT hop, unlike dev's .50.

New infra/workstation/dnsmasq/ — authored, not click-ops:
  20-prod.home.keithjackson.dev.conf   prod.home.* -> 192.168.2.20 (Gateway),
                                       unifi -> .21, crafty-mc -> .22 (L4 VIPs)
  install.sh                           installs + reloads; refuses non-root

dnsmasq resolves `address=` by LONGEST MATCH, so the prod rules win WITHOUT
editing or reordering the dev profile. PROVEN, not assumed: ran a throwaway
dnsmasq on 127.0.0.1:5354 loaded with both profiles —
  prod.home / gitea.prod / keycloak.prod -> 192.168.2.20
  unifi.prod -> 192.168.2.21   crafty-mc.prod -> 192.168.2.22
  gitea.home / home.keithjackson.dev     -> 192.168.2.50  (DEV, UNCHANGED)
`dnsmasq --test` on the new file: syntax OK.

install.sh pins the destination because getting it wrong is SILENT: a file in
/etc/dnsmasq.d exists, looks installed, and changes nothing. It also uses
`systemctl reload NetworkManager` rather than SIGHUP — dnsmasq does not re-read
its config on SIGHUP, so a HUP would look like it worked and not apply anything.

WHY THE MISLABEL MATTERED: the trap PARTIALLY works. Dev serves a
*.home.keithjackson.dev wildcard cert, which matches prod.home.keithjackson.dev
(one label) so the prod apex returns 200 over VALID TLS, while
keycloak.prod.home.keithjackson.dev (two labels) fails with a certificate-name
error. It reads as a broken prod cert; it is the wrong server answering. I made
exactly that misreading during verification.

Also recorded, because it changes what the apex flip IS: the SOHO router NATs
inbound 443 to the pfSense WAN (192.168.2.102) to serve the EXISTING NON-K3S
production environment, which must stay live until the switch is deliberately
made. So §10a sequence P is not just a k3s-side DNS/TLS change — it is the
legacy-prod cutover, and P as written does NOT cover repointing that NAT. The
two must be planned together or the apex resolves to k3s while inbound 443 still
lands on the legacy box. Phase C touches none of it: prod's Gateway is
192.168.2.20:443 (a different address) and its cert is DNS-01, needing no
inbound 443. And the MinIO timeout is now correctly described as expected
topology — crossing INTO pfSense from its WAN — not a misconfiguration.

VERIFIED: full CI gate PASS (spec-immutability, lint, l0, render-golden, l1).

jakman85andClaude Opus 5 b80e8eef82 feat(backup): prod shares dev's MinIO — plus the path tenancy that makes it survivable
Operator ruling: "the S3 backup location is the same as Dev." Prod's
S3_BACKUP_ENDPOINT is now http://192.168.1.9:9000 and the TBD-PROD-* placeholder
is retired. Set EXPLICITLY rather than by omitting the op — an omitted op would
inherit the same value silently, and a shared backup target must be visible in
the overlay that owns it.

SHARING THE ENDPOINT WAS NOT SAFE AS AUTHORED. Nothing about the backup PATHS
was per-environment, and enabling prod against dev's MinIO would have been the
2026-09-04 external-dns incident again, in a worse place:

  VELERO — bucket `velero`, NO prefix, and both clusters run schedules named
    `daily` / `daily-resources-only`. Velero SYNCS backups it finds in its BSL
    into itself as Backup CRs and GARBAGE-COLLECTS them at TTL, so prod would
    have adopted dev's backups and then deleted them on schedule.
  CNPG — the worse one. destinationPath `s3://cnpg` with CNPG appending
    serverName, which defaults to the CLUSTER NAME. Both environments have
    keycloak-db, nextcloud-db and semaphore-db, so prod's Postgres would archive
    WAL into the EXACT prefix dev's does. Two servers interleaving WAL into one
    Barman stream CORRUPTS THE CHAIN and destroys PITR — and dev's restore is
    PROVEN (R-STATE-03). Sharing an endpoint is fine; sharing a path is not.

Two knobs, authored once, environments differing only by scoped overrides
(R-ENV-02):
  VELERO_BACKUP_PREFIX  dev ""          | prod "prod"
  CNPG_BACKUP_PATH      dev "s3://cnpg" | prod "s3://cnpg/prod"

THE BASE VALUES ARE DEV'S CURRENT LAYOUT ON PURPOSE. Dev's existing backups live
at the bucket root and at s3://cnpg; giving dev a prefix would ORPHAN the very
backups its proven restore depends on — the same reasoning that keeps dev's
EXTERNALDNS_TXT_OWNER_ID at `default`. Prod has no history to preserve.

*** PROD STILL HAS NO BACKUP COVERAGE — the endpoint is not reachable. ***
Measured from a throwaway pod INSIDE the prod cluster (the workstation proves
nothing about pod egress, and a workstation-side reading has already misled this
project once): curl http://192.168.1.9:9000/minio/health/live → connection timed
out after 15s. pfSense does not route prod's pod network to the dev LAN's MinIO.
OPERATOR ACTION REQUIRED. velero stays suspended; note apps-wave-0 applies GREEN
regardless — the token IS defined so strict substitution succeeds — while every
write fails at RUNTIME. A green apps-wave-0 does not mean backups work.

New `standup.sh s3check` step probes the endpoint from a throwaway in-cluster
pod and fails closed, with `--s3-endpoint <url>` to test a CANDIDATE before
authoring it into cluster-vars. That is how the unreachability above was
established rather than assumed.

VERIFIED: full CI gate PASS. flux-postbuild-substitution 254 -> 260 assertions,
and neither new knob appears in the dead-knob advisory list, so both are really
consumed. Rendered both overlays: all three CNPG destinationPaths and Velero's
prefix carry the tokens; dev resolves to its existing layout, prod to the nested
paths.

DELIVERY: prod reconciles the bootstrap Gitea's main at c8c1d29. This branch also
carries the DNS inversion, which must NOT reach prod. Delivering needs a
c8c1d29-based branch with only these commits — no urgency while the routing is
still closed.

jakman85andClaude Opus 5 acb5cabdad fix(standup): preflight must always report — it was an env fork in disguise
preflight `die`d when EXTERNALDNS_TXT_OWNER_ID was empty, the sentinel, or
`default`. Two problems, found by pointing it at dev:

1. `default` is DEV'S LEGITIMATE owner id — its live records are registered
   under it and cannot be renamed without orphaning them. Dying on it meant a
   script whose entire claim is "environment-agnostic, no dev/prod fork"
   (R-ENV-02) could never run against dev at all. That is a fork in disguise.

2. Dev's value is currently EMPTY, because dev runs dev-live@a4a3c2e — based on
   main@4809199, which predates the commit that added the knob. That is dev's
   long-standing status quo, not a fault. The die hid the ENTIRE remaining
   health report behind it, which is backwards for a diagnostic.

preflight is now a pure diagnostic: it always finishes and reports, and the only
thing it refuses over is the --expect-server target guard, because that one
means you are pointed at the wrong cluster. Bad owner-id values are reported
with a warning explaining why each is dangerous and for whom.

THE REFUSAL MOVES, IT DOES NOT DISAPPEAR: step_externaldns — the MUTATING path,
where acting on a bad value is what actually deletes another cluster's records —
still dies on empty, sentinel and `default`. Verified both halves after the
change: prod preflight still reports "distinct and non-default: OK", and the
mutating guard is intact.

Confirmed with it: dev is 13/13 Kustomizations Ready on dev-live@a4a3c2e, all
HelmReleases Ready, nothing suspended — healthy throughout prod's standup.

jakman85andClaude Opus 5 4f37fc375e feat(prod): STANDUP COMPLETE — 12/13 tiers Ready, LE wildcard issued, dev untouched
Prod is up and serving. 113 pods, 0 not Running/Completed. wildcard-home
Certificate Ready (Let's Encrypt PROD, *.prod.home.keithjackson.dev). Gateway
VIP 192.168.2.20, crafty L4 .22, unifi L4 .21. 36 DNS records published under
prod.home.keithjackson.dev, every TXT registry entry owner=prod.

End-to-end HTTPS with certificate validation (no -k), pinned to prod's gateway:
apex 200, keycloak 302 (login), gitea 200, grafana 302 (SSO).

DEV UNTOUCHED: all 57 pre-existing records byte-identical to the pre-standup
baseline. velero remains suspended — S3_BACKUP_ENDPOINT is still the TBD
placeholder, and resuming it would create a BackupStorageLocation that can never
reach a bucket: a tier reporting healthy while backups silently do not exist.

TWO BUGS IN MY OWN VERIFICATION, both of which would have made the safety check
worthless. Recording them because a check you cannot trust is worse than none —
it trains you to skip the one alarm that matters.

1. SNAP_DIR defaulted to $TMPDIR. Every `dev.sh run` is a FRESH container, so the
   DNS baseline was discarded between steps and `verify`'s before/after
   comparison — the check that detects damage to the other cluster's records —
   could never run across invocations. Now repo-relative (bind-mounted, so it
   persists on the host) and gitignored as a run artifact.

2. The first real comparison cried wolf: "RECORDS OUTSIDE prod.home CHANGED",
   listing pairs of IDENTICAL lines. Cause was locale-dependent sort collation —
   the host ordered `*.keithjackson.dev` differently from the container, so a
   diff of two identical sets reported changes. Proved it was noise by
   re-comparing under LC_ALL=C: all 57 records identical. dns_snapshot now strips
   CRs and sorts under LC_ALL=C so ordering is reproducible everywhere.

ACTION REQUIRED (operator, pfSense): the local override is a wildcard on
*.home.keithjackson.dev and now also swallows the new prod.home.* subtree,
resolving EVERY prod hostname to 192.168.2.50 (dev). Cloudflare correctly
returns 192.168.2.20. Prod is reachable from anywhere using public DNS, but NOT
from behind pfSense. Narrow the override, or add one pointing prod.home.* at
192.168.2.20.

That override is also the trap that produced a false healthy reading during the
2026-09-04 incident, and it is subtle because it PARTIALLY works: dev's
*.home.keithjackson.dev wildcard matches prod.home.keithjackson.dev (one label)
so the apex returns 200 over valid TLS, while keycloak.prod.home... (two labels)
fails with a certificate-name error. I hit this myself during verification and
mistook it for a broken prod cert. Never verify DNS or TLS here through a local
resolver.

jakman85andClaude Opus 5 1b056dc9d9 fix(prod): break the CDI cold-start deadlock, and make preflight catch its class
`platform-config` stopped dead on prod:

    StorageProfile/longhorn dry-run failed: no matches for kind
    "StorageProfile" in version "cdi.kubevirt.io/v1beta1"

A TRUE DEADLOCK, not a transient. platform-config applies the CDI CR *and*
platform/kubevirt/cdi-storageprofiles.yaml in the SAME pass. StorageProfile's
CRD does not exist until cdi-operator has reconciled that CR — and Flux
server-side dry-runs EVERY object before applying ANY of them, so the unknown
kind aborts the whole tier, the CR is never applied, the CRD is never created,
and platform-config can never converge. Every tier below it stays blocked.

Same root cause as the Kyverno CRD bundle, different operator: Flux cannot order
a resource against a CRD that one of its own siblings is responsible for
creating. It is INVISIBLE on an established cluster — dev's CDI CRDs have been
there for months — and fatal on a cold one. Observed on prod: cdi-operator
Available for 12h, no CDI CR, no storageprofiles CRD.

`crds` now breaks it by applying ONLY the CDI CR — the minimum — and leaving
every other object to Flux. The CR carries no ${} tokens, so applying it here
cannot diverge from what Flux would render. It refuses if the `cdi` namespace is
absent (platform has not run yet) rather than applying into nothing, waits for
the CRD, and requires it to reach Established. On prod the CRD appeared in 10s
and platform-config was unblocked.

`preflight` now reports the CRDs that later tiers apply resources against
(storageprofiles/cdis/kubevirts/volumesnapshotclasses) and dumps the cdi
namespace when one is missing, so this is caught in seconds instead of after
`resume` burns its 900s wait discovering it. It also names the stale-discovery-
cache variant, which presents identically but clears on a forced reconcile.

THE DURABLE FIX IS A REPO CHANGE, deliberately NOT made here: move
cdi-storageprofiles.yaml out of platform-config into its own Kustomization with
dependsOn: platform-config, so the CR lands one reconcile before the resources
needing its CRDs. That edits the reconciliation graph both clusters share, and
prod currently reads a pinned revision from the bootstrap Gitea while dev is
mid-migration on a separate branch — so it wants doing deliberately, not at
02:00 to unblock a bring-up. Until it lands, C2 is a prerequisite for C5 on any
cold cluster, and PROD-STANDUP.md says so.

jakman85andClaude Opus 5 4160fee6ce feat(prod): standup.sh + PROD-STANDUP.md — the complete standup sequence, in git
The last steps of a prod bring-up were living in shell history: resume the
tiers in the right order, clear a wedged HelmRelease, fix external-dns without
deleting the other cluster's DNS. That is the same failure the Kyverno CRD
pre-apply had, so it gets the same treatment.

bootstrap/standup.sh — environment-agnostic (R-ENV-02), no dev/prod fork. Six
idempotent steps: preflight, crds, unwedge, externaldns, resume, verify.

THE GUARD IS THE POINT. --expect-server is MANDATORY and is compared against
the live API server before any step runs; there is no override flag. Dev is
live and shares the keithjackson.dev Cloudflare zone with prod, and on
2026-09-04 prod deleted every one of dev's public records. Negative control
run: prod's kubeconfig with dev's server URL refuses and changes nothing.

preflight fails closed if EXTERNALDNS_TXT_OWNER_ID is empty, still the base
sentinel, or `default` (dev's owner) — the exact condition that caused the
incident. It also surfaces SUSPENDED HelmReleases separately, because a
suspended release keeps its last Ready condition and a stale `Ready=True`
otherwise hides that Flux is not managing it at all (external-dns today).

externaldns is the dangerous step, and the ordering IS the mitigation. A Helm
upgrade resets replicas to 1 and applies new args in ONE operation, so there is
no window to check the result first; if --txt-owner-id were missing the pod
starts as owner `default` and syncs away dev's records. So the step PROVES THE
OUTCOME BEFORE CAUSING IT: render the chart with the LIVE HelmRelease values and
assert --txt-owner-id=<owner> appears, aborting if not. Rendering is
deterministic and touches nothing, which turns a race into a precondition. Then
snapshot Cloudflare, upgrade, re-verify live args (scale to 0 and fail if
wrong), and diff the zone.

resume walks the dependency order and STOPS at the first tier that does not go
Ready — a partial understood bring-up beats a forced green. velero is skipped
while S3_BACKUP_ENDPOINT is the TBD placeholder.

TWO BUGS CAUGHT WHILE VALIDATING THIS, both by measuring instead of assuming:

1. preflight counted Kyverno CRDs with grep 'kyverno.io' and reported 20 of 22
   — the policy-report types are in the wgpolicyk8s.io group. A preflight that
   under-reports reads as "the pre-apply failed" when it succeeded. Fixed and
   re-run: 22.

2. The documented node-health invocation used -e k3s_hosts=k3s_prod and
   SILENTLY RAN AGAINST DEV'S THREE NODES. Diagnostic plays deliberately keep
   their own target var (node_health_hosts, memattr_survey_hosts,
   vpn_egress_gateway_hosts) so they stay pointable while a bring-up is scoped
   elsewhere — a good design I did NOT change. The hazard is that the wrong flag
   does not error, it falls through to the dev default. Caught only by
   --list-hosts; the doc now leads with that warning and a dry-run command.
   Verified after fixing: node-health and all six site.yml plays target prod.

.claude/settings.local.json — permission rules for the above. Every entry
hardcodes prod's kubeconfig AND prod's --expect-server (or prod's ansible
groups), so the permission strings are themselves prod-scoped and cannot be
turned against dev. Deliberately NO rule for `dev.sh run bash -c *`, which
would have been blanket cluster access wearing a narrow-looking mask.

jakman85andClaude Opus 5 7432012713 docs(prod): platform tier up 8/9 — and TWO blockers, one of them an armed footgun
Unsuspended prod's `platform` after pre-applying the Kyverno CRDs.
8/9 HelmReleases Ready, 76/76 pods Running (cert-manager, CNPG, Cilium,
Longhorn, kube-prometheus-stack, Loki, Alloy, external-dns). `platform` itself
is NOT Ready and the 10 downstream tiers stay blocked.

THE CRD PRE-APPLY WORKED and is now proven against a live API server: 22 CRDs
Established, a second run a clean no-op (rc=0), reproduced under the PINNED
toolchain (helm 3.16.0) matching the 3.20.0 run byte-for-byte. It also confirmed
the predicted failure mode: Kyverno's Deployments had 55 RESTARTS EACH over 4.5h
and stabilised within minutes of the apply — controllers with no API types.

BLOCKER 1 — Kyverno's Helm release is wedged in `uninstalling`. The install
timed out *because* of that crash loop; install.remediation.retries:3 then fired
an uninstall which ALSO timed out, leaving sh.helm.release.v1.kyverno.v1 at
status=uninstalling. helm-controller cannot advance from there, so `platform`
(wait: true) never goes Ready. The Deployments themselves are healthy at the
right chart version — this is stale Helm bookkeeping, not a broken workload.
Fix needs `helm uninstall` + `flux reconcile --force`; destructive, so NOT run
unattended. Safe here because prod carries no workloads and a cold install
proves the bootstrap path. The pre-applied CRDs live OUTSIDE the release and
survive the uninstall — precisely why the pre-apply is a separate step.

BLOCKER 2 — AND THIS ONE IS ARMED. Prod's external-dns Deployment runs
--policy=sync --registry=txt --domain-filter=keithjackson.dev WITH NO
--txt-owner-id. Absent that flag it defaults to `default` — the owner of ALL 36
of dev's TXT registry entries. Scaling it to 1 would claim dev's records and,
under policy: sync, DELETE THEM: the 2026-09-04 incident, exactly.

The repo is not at fault. helmrelease.yaml sets txtOwnerId from cluster-vars,
prod resolves it to `prod`, and the LIVE HelmRelease spec.values carries
txtOwnerId: "prod". Verified against the real chart: 1.21.1 with txtOwnerId:
prod renders --txt-owner-id=prod, so the key is right and an upgrade would fix
it. The fault is Helm/Flux STATE: `helm get values` shows the installed release
has policy and domainFilters but NO txtOwnerId — it predates c8c1d29 — while
helm-controller reports Ready=True, observedGeneration=3, and a history entry
whose configDigest EQUALS lastAttemptedConfigDigest. It believes it already
deployed the current config, so it will never upgrade on its own.

The only thing that prevented the incident was replicas=0 — manual drift from
the incident recovery, which any Helm upgrade resets to the chart default of 1.
That is not a guard, it is luck.

CONTAINED: `flux suspend helmrelease external-dns`, replicas left at 0. Costs
nothing (prod publishes no hostnames yet; app tiers suspended) and is reversible.
Remediation ordering matters and is documented: the naive resume + reconcile
--force adds the flag and starts the pod in ONE operation, leaving no window to
verify — a race whose failure mode is deleting dev's DNS. Pin replicas at 0,
confirm --txt-owner-id=prod in the live args, THEN scale.

Dev verified unharmed throughout: Cloudflare snapshotted before the unsuspend
and re-queried after — 57 records byte-for-byte identical, 36 TXT still
owner=default. Queried against the Cloudflare API, never a local resolver.

jakman85andClaude Opus 5 6b88670129 docs(prod): D0/D1 as executed, and CORRECT the P1 gate — it guards the apex, not prod
Two runbook corrections from executing step A of the dev migration.

1. P1 said "only NOW unsuspend prod", gated on D8 (dev's apex vacated). That
   silently assumed prod would be serving the bare apex. IT IS NOT. Prod runs
   c8c1d29, where BASE_DOMAIN=prod.home.keithjackson.dev and
   EXTERNALDNS_TXT_OWNER_ID=prod — verified live in prod's applied cluster-vars.
   Prod's names are a DISJOINT SUBTREE under a DISTINCT registry owner, so
   neither §10a incident mode applies: it cannot claim dev's `default`-owned
   records, and *.prod.home.keithjackson.dev is a DIFFERENT name set from dev's,
   so it has its own Let's Encrypt duplicate-cert bucket and races no
   _acme-challenge with dev. Prod can therefore be brought up IN FULL while dev
   still holds the apex — and should be, because it proves the whole stack
   before the flip, turning the cutover into a DNS/TLS change on a known-good
   cluster rather than a bring-up and a cutover simultaneously. D8 gates ONLY
   the later move of prod's BASE_DOMAIN to the apex.

2. D1 was executed via the REPOINT option, not suspend — repointing removes the
   dependency that causes the strand instead of merely deferring it. Dev now
   fetches from http://192.168.2.132:3000/... branch `dev-live`: IP-addressed,
   plain HTTP, dependent on NEITHER DNS NOR TLS, which is the property a DNS/TLS
   migration needs. A merge to `main` is now inert for dev.

   THE TRAP, recorded because it is not obvious: a bare copy of main@4809199 on
   the bootstrap Gitea would NOT have held. The root renders ./clusters/dev, and
   clusters/dev/kustomization.yaml CONTAINS the patch that sets
   GitRepository.spec.url — so Flux would have fetched from the bootstrap Gitea
   and then applied manifests that set the url straight back, reverting the
   repoint and re-arming the strand. The branch must declare its own source.
   dev-live (a4a3c2e) carries exactly one content change on 4809199, proven by
   `kubectl kustomize clusters/dev` differing in EXACTLY TWO of 357 lines.

   NEW DEPENDENCY, and it is the weak link: 192.168.2.132 is a DHCP lease on the
   workstation's WIFI (wlp0s20f3, NetworkManager ipv4.method=auto — confirmed by
   inspection, not assumed). A lease change or the workstation going offline
   stalls dev's FETCHING; the cluster keeps serving and the fix is a kubectl
   patch. Hence: a static reservation is worth having, and the window should be
   kept short — the exit is D4. Pointing Flux at gitea.gitea.svc.cluster.local
   would drop the DNS, TLS and workstation dependencies at once and is the better
   long-term shape, but namespace `gitea` has default-deny plus a Cilium policy
   admitting only the Gateway, so it needs a new authored policy — deliberately,
   not mid-migration.

Post-cutover verification: 13/13 Kustomizations Ready on dev-live@a4a3c2e,
cluster-vars byte-identical to the D0 snapshot (BASE_DOMAIN still the apex),
18/18 Longhorn volumes attached+healthy, all 16 HTTPRoute hostnames unchanged,
and the Cloudflare record set re-queried and diffed byte-for-byte against D0 —
identical, 57 records, 36 TXT all owner=default.

jakman85andClaude Opus 5 13081a863f feat(bootstrap): automate the Kyverno CRD pre-apply — the last cold-start blocker
`platform/kyverno/admission/helmrelease.yaml` sets `crds: {install: false}`
because the CRD bundle is 5,636,155 bytes, far past kubectl's 256 KiB
last-applied-configuration limit — a client-side apply fails with
"metadata.annotations: Too long" and STALLS the HelmRelease.

The consequence nobody automated: with CRD install off, NOTHING installed
them. `platform` has `wait: true` and every other tier chains transitively
through it, so on a cold cluster Kyverno's API types never exist, `platform`
never goes Ready, and all 10 downstream tiers stall. Dev only ever had these
CRDs because they were applied BY HAND — exactly the undocumented manual step
this repo exists to eliminate.

New `bootstrap/flux/preapply-crds.sh`, wired into bootstrap.sh as step [2/4]
(after `flux install`, before the graph is applied) and standalone-safe so an
already-bootstrapped cluster can be unblocked without re-running bootstrap.

NO SECOND PIN: all four chart coordinates are read with yq out of the same
HelmRelease/HelmRepository pair Flux reconciles. The version is passed through
as the CONSTRAINT ("3.9.x"), not a resolved tag — helm and helm-controller both
use Masterminds/semver, so the render is the version Flux installs. Renovate
bumps one line and this step follows; there is nothing here to drift from.

Only `kind: CustomResourceDefinition` documents are applied. The by-hand
command recorded in the HelmRelease comment piped the WHOLE template into
kubectl, which would create Deployments/webhooks outside Helm's ownership and
then fight the HelmRelease over field managers.

THREE GUARDS, because a silent skip here reproduces a failure mode this repo
has been bitten by repeatedly:
  1. any derived coordinate that is empty/null/multi-valued aborts;
  2. rendered CRD count must be > 0 — this caught a real bug in the first
     draft: on an empty render `yq .metadata.name` emits one BLANK line, which
     counted as 1 CRD and sailed past the guard into an apply of an empty file
     returning 0, i.e. the exact silent-success trap. Blank/null lines are now
     dropped and a chart with no CRDs exits 1;
  3. every applied CRD is waited on for condition=Established, so "kubectl
     returned 0" is not the only evidence.
No opt-out flag, deliberately: a skipped CRD apply yields a cluster that looks
bootstrapped and reconciles nothing.

`roles/flux_bootstrap` is untouched — it already shells to bootstrap.sh, the
documented single entrypoint, so it inherits the step with no dev/prod fork
(R-ENV-02). A second role task would double-apply.

MEASURED, not assumed — reproduced under the PINNED toolchain (helm 3.16.0,
yq 4.44.6) in infra/devcontainer, matching an independent run on helm 3.20.0
byte-for-byte: 3.9.x resolves to 3.9.0, 22 CRDs, 5,636,155 bytes CRD-only
(5,870,019 full render). Largest single CRD document is 1,378,544 bytes —
under etcd's 1.5 MiB default, but not by much; worth watching on chart bumps.

NOT YET EXERCISED against a live API server: the server-side apply and the
Established wait were tested with a stub kubectl. velero and
kube-prometheus-stack also say "CRDs pre-applied" but both still get theirs
from Helm's native crds/ dir on FIRST install, so neither is a cold-start
blocker; CRD_HELMRELEASE makes extending this a one-liner if that changes.

- **Prod's source URL cannot work on a cold prod cluster** — split-horizon answers the whole zone
with `${GATEWAY_VIP}`, so prod would resolve `gitea.home.keithjackson.dev` to its own gateway.
Bring-up needs a temporary source and a cutover, as `docs/05` describes for dev's own Phase-6.
## 2026-09-05 — **PROD IS UP.** Overnight standup: 12/13 tiers, LE wildcard, dev untouched
Operator asleep; standing instruction was "finish out what is necessary and I want it working by
the morning." **Prod is serving.** Dev was verified unharmed at every step.
### Final state
| | prod | dev |
|---|---|---|
| Kustomizations | **12/13 Ready** (`velero` suspended, deliberately) | **13/13 Ready** |
| Source | bootstrap Gitea `main@c8c1d29` | bootstrap Gitea `dev-live@a4a3c2e` |
| `BASE_DOMAIN` | `prod.home.keithjackson.dev` | `home.keithjackson.dev` (apex) |
| Pods | **113, 0 not Running/Completed** | healthy, all HelmReleases Ready |
| Wildcard cert | **Ready** — LE prod, `*.prod.home.keithjackson.dev` | unchanged |
| DNS | **36 records**, every TXT `owner=prod` | **57 records, byte-identical to baseline** |
End-to-end HTTPS with certificate validation, pinned to prod's gateway: apex `200`,
keycloak `302` (login), gitea `200`, grafana `302` (SSO).
### What was actually blocking, and what it taught
**Both blockers were the same bug in different clothes: Flux server-side dry-runs every object in a
Kustomization before applying any of them, so ONE unknown `kind` aborts the entire tier.**
1. **Kyverno** — chart sets `crds.install: false` (5.6 MiB bundle > kubectl's 256 KiB annotation
limit) and nothing else installed them. Its pods had **55 restarts each over 4.5h**, controllers
with no API types to watch. The failed install then tripped `install.remediation.retries: 3`,
whose uninstall ALSO timed out, wedging the release in `uninstalling` — a state helm-controller
cannot advance from. Cleared with `helm uninstall` + a cold reinstall.
2. **CDI — a true deadlock, and the one worth remembering.** `platform-config` applies the CDI CR
*and* `cdi-storageprofiles.yaml` in the SAME pass, but `StorageProfile`'s CRD does not exist until
`cdi-operator` reconciles that CR. Dry-run fails → CR never applied → CRD never created → the tier
can NEVER converge. `cdi-operator` had been Available for **12h** with no CR. **Invisible on dev**
(its CDI CRDs have existed for months) **and fatal on any cold cluster.** Broken by pre-applying
only the CR; the CRD appeared in 10s.
> **DURABLE FIX STILL OWED:** move `cdi-storageprofiles.yaml` out of `platform-config` into its own
> Kustomization with `dependsOn: platform-config`. Not done overnight — it edits the reconciliation
> graph both clusters share, while prod reads a pinned revision and dev sits mid-migration on a
> separate branch. Until it lands, `standup.sh crds` is a prerequisite on any cold cluster.
### The armed footgun, disarmed
Prod's external-dns Deployment was running `--policy=sync --registry=txt
--domain-filter=keithjackson.dev` **with no `--txt-owner-id`** — it would have defaulted to `default`,
the owner of **all 36 of dev's TXT registry entries**, and `policy: sync` would have deleted the
records behind them. The 2026-09-04 incident, re-armed. **The only thing preventing it was
`replicas=0` — manual drift that any Helm upgrade resets to the chart default of 1. That is not a
guard, it is luck.**
The repo was never at fault: the live HelmRelease `spec.values` carried `txtOwnerId: "prod"`. The
fault was Helm/Flux STATE — the installed release predated `c8c1d29`, yet helm-controller reported
`Ready=True` with `configDigest == lastAttemptedConfigDigest`, believing it had already deployed the
current config, so it would never have upgraded on its own.
**The fix pattern is the reusable part: PROVE THE OUTCOME BEFORE CAUSING IT.** A Helm upgrade sets
replicas to 1 and applies new args in one operation — there is no window to check first. So
`standup.sh externaldns` renders the chart with the LIVE values and asserts `--txt-owner-id=<owner>`
appears, aborting if not. Rendering is deterministic and touches nothing, which converts a race into
a precondition.
### Three bugs in my own verification — recorded because a check you cannot trust is worse than none
1. **`SNAP_DIR` defaulted to `$TMPDIR`.** Every `dev.sh run` is a fresh container, so the DNS baseline
was discarded between steps and the before/after comparison — the check that detects damage to the
other cluster — could never run across invocations. Now repo-relative and gitignored.
2. **The first real comparison cried wolf**, reporting "RECORDS OUTSIDE prod.home CHANGED" and listing
pairs of IDENTICAL lines. Locale-dependent sort collation: the host ordered `*.keithjackson.dev`
differently from the container. Proved it was noise under `LC_ALL=C` (all 57 identical); snapshots
now strip CRs and sort under a fixed collation.
3. **preflight `die`d on `EXTERNALDNS_TXT_OWNER_ID=default`** — dev's legitimate id — so a script
claiming "no dev/prod fork" (R-ENV-02) could never run against dev. A fork in disguise. preflight
is now a pure diagnostic; the refusal moved to the mutating path where acting on a bad value is
what actually causes harm.
### I also fell into the pfSense trap — ACTION REQUIRED
The local override is a wildcard on `*.home.keithjackson.dev` and now swallows the whole new
`prod.home.*` subtree, resolving **every prod hostname to `192.168.2.50` (dev)**. Cloudflare
correctly returns `192.168.2.20`.
**Prod is reachable from anywhere using public DNS, but NOT from behind pfSense.** Narrow the
override, or add one pointing `prod.home.*` at `192.168.2.20`.
It is subtle because it **partially works**: dev's `*.home.keithjackson.dev` wildcard matches
`prod.home.keithjackson.dev` (one label) so the apex returns 200 over valid TLS, while
`keycloak.prod.home.keithjackson.dev` (two labels) fails with a certificate-name error. I read that
as a broken prod cert before checking the resolver. **This is the same trap that produced the false
healthy reading during the incident. Never verify DNS or TLS here through a local resolver.**
### Still open for the operator
- **`S3_BACKUP_ENDPOINT` is `TBD-PROD-*`** — `velero` stays suspended, and note `apps-wave-0` consumes
it too and applies GREEN while anything writing there fails at runtime. **Prod has no backup
coverage.** Needs a real prod endpoint (prod cannot reach dev's `192.168.1.9:9000`).
- **Dev's migration off the apex** (§10a sequence D) — Keycloak issuer, ~12 OIDC redirect URIs, a
rolling k3s restart that invalidates every OIDC kubeconfig. Operator-present.
- **Dev's GitOps source is this workstation** — `192.168.2.132` is a **DHCP lease on wifi**. A lease
change stalls dev's fetching (cluster keeps serving; fix is a `kubectl patch`). Static reservation.
- **Six L2 tests hardcode the apex** and must be parameterized per environment.
- Nothing merged to `main`; nothing pushed. `infra/PROD-STANDUP.md` is the command sequence.
## 2026-09-05 (afternoon) — **PM autonomous session.** Backups to R2, CDI deadlock repaired, coverage 82%→88% — and a guard I broke
Operator away ~2h, PM directed to work autonomously through agents. Four agents ran;
every result was re-verified by the PM before commit. **Nothing merged, nothing pushed.**
Both clusters healthy throughout — dev 13/13, prod 12/13 (velero deliberately suspended).
Commits: `32d6766` R2 · `765ad03` CDI · `59ffbaf` L2 params · `8f9b2e4` s3check · `fe45d0f` coverage.
### THE MISTAKE, AND WHY IT MATTERS MORE THAN THE FEATURES
In `32d6766` I changed the backup placeholder from `TBD-PROD-S3-BACKUP-ENDPOINT` to
`https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com`. The guards in `standup.sh` matched
`TBD-*` — a **prefix** glob. `fnmatch('https://TBD-R2-…','TBD-*')` is **False**, so all three
guards silently died, and **`resume` would have enabled velero on prod against a nonexistent
hostname**: installs clean, reports healthy, no backup exists. Precisely the failure the guard
existed to prevent, disarmed by a value change in a *different file*.
**The class, now seen three times today** (this; the CRD count that read a blank line as `1`;
two coverage checks that passed when perturbed): *a check that degrades to success*. The
structural lesson is narrower and worth keeping — **a guard keyed on a value's SHAPE, where the
value lives in another file, has no test tying the two together.** Fixed by substring match;
a test for the coupling is **not** yet written and should be.
### Operator decisions waiting
1. **R-TLS-02 "revoked" is NOT satisfied — a real platform gap.** The spec requires certs be
"issued, renewed, **and revoked** without manual steps"; docs/08 reads revocation as a
declarative removal. That needs `enableCertificateOwnerRef: true`, which
`platform/cert-manager/helmrelease.yaml` does not set (chart default false). **Verified on
both live clusters: `gateway/wildcard-home-tls` has ZERO ownerReferences** — deleting the
Certificate leaves the private key serving indefinitely.
**Deliberately not flipped.** The wildcard Certificate is under `./platform`, which runs
`prune: true`. With owner refs ON, a transient prune of that Certificate — *exactly what
happened to the CDI StorageProfiles today* — deletes the SERVING TLS Secret for every host,
and reissuance is bounded by LE's duplicate-certificate limit (5/week per identical name set),
risking **no trusted cert for a week**. Security gap vs plausible week-long outage: operator's
call. The L2 test asserts the requirement as written and **will fail until decided** — it was
not softened.
2. **R2 needs the two token values.** `infra/BACKUP-R2.md` is the procedure. The **account id is
already committed** (`infra/tofu/backend.r2.hcl` → `7ce452a1b3d6c86daf2c020edcb82d37`), so if
the buckets go in that account only the token is missing. Placeholder kept on purpose.
3. **The apex flip is also the legacy-prod 443 cutover.** The SOHO router NATs inbound 443 to the
pfSense WAN for the non-k3s prod. §10a sequence P does not cover repointing it.
### Merge preconditions — read before merging anything here
- **CDI split:** `flux get kustomization platform-config` must be **Ready on the target first**.
Otherwise the two StorageProfiles are pruned and sit at CDI defaults until it recovers (prod was
in that state hours earlier). Measured exposure: CDI unaided infers **ReadWriteOnce**
(`longhorn-static`) where we author **ReadWriteMany** (`longhorn-vm`) — so a DataVolume created
in the ~30–60s window is **permanently non-live-migratable**. `cloneStrategy` is *not* at risk.
- **R2 switch RESETS dev's PITR window** — fresh kopia repo, new CNPG base backups, the 30-day
Barman window rebuilds from zero. The MinIO copy is retained and restorable.
- **R-STATE-03 is PROVEN MinIO-ONLY** and its ledger row predates the R2 move. `BACKUP-R2.md` §5
is the re-proof and it ends in a **restore**, not an upload.
### Findings worth keeping
- **Second-order CRDs need a third pass.** A CR whose CRD is created by a *controller at runtime*
cannot share a Kustomization with resources of that CRD. `cdi-operator` registers exactly one
CRD; `storageprofiles`/`datavolumes`/`datasources` appear only after it reconciles the CDI CR.
Audit found `StorageProfile` was the only second-order kind in `platform-config`.
- **`dns-exposure`'s teardown is ASYNCHRONOUS.** It reports PASS when chainsaw deletes the
namespace; the Cloudflare record is reaped later by external-dns's 1-minute sync. A green run
does **not** prove cleanup — if external-dns were suspended the record would persist silently.
(Observed, then observed clearing.)
- **The apex was not the only per-environment literal in the L2 suite** — two DNS tests hardcoded
dev's LB range `192.168.1.53-.60`. They now assert the *observed* `GATEWAY_VIP` / assigned LB IP,
which is stricter as well as portable.
- **Velero's kopia backend has no checksum knob**, so BSL metadata and PVC-data R2 compatibility
are **separate questions**. CNPG's boto3 1.35.60 is below the 1.36 default-checksum line — clear
today, but **a CNPG image bump is an R2 re-verification event** (barman-cloud has no escape hatch).
- **`ansible-inventory --list` prints DECRYPTED vault values** (the passphrase file is mounted into
the dev container). It emitted the prod become-password to an agent's stdout. Never put it in CI.
Confirmed no plaintext reached disk.
## 2026-09-06 — Prod solidified. Node 2 at full 32 GB, storage recovered, four latent cold-start bugs closed
Operator away; PM directed to oversee, delegate, and pay down debt while skipping anything needing
their input. Five agents ran; every result re-verified by the PM before commit. **Nothing merged,
nothing pushed. Both clusters healthy.**
Commits: `04569ab` node-maintenance runbook · `da3e9cc` Kyverno/CDI · `a984442` timezone + guard test.
### PROD IS FUNCTIONING
| | |
|---|---|
| Nodes | 3/3 Ready, **all three at ~`32638256Ki`** — node 2's DIMM upgrade landed, matching 1 and 3 to within 4 KiB |
| Flux | **12/13 tiers Ready** (`velero` suspended: no backup endpoint) |
| Pods | **112 Running**, 0 Running-but-NotReady |
| Storage | **17/17 volumes healthy**, replicas symmetric 17-running+1-stopped per node |
| TLS | LE wildcard `*.prod.home.keithjackson.dev` Ready |
| etcd | 3 members, survived an ungraceful power-down without losing a member |
The memattr saga (§0b) is **closed on the hardware side**: with the 7.1.8 backports kernel, all three
nodes address their full 32 GB.
### THE FINDING THAT MATTERS MOST — a failed drain silently stops storage self-healing
`kubectl drain` **cordons before it fails**, and Longhorn's `disable-scheduling-on-cordoned-node` is
`true`. After prod-2's memory-upgrade reboot, **all 17 volumes sat `attached/degraded` with prod-2
holding 2 of 18 replicas and ZERO rebuilds in flight** — nothing driving recovery, every pod
`Running`, no alert. `kubectl uncordon` started rebuilds immediately; converged 17/17 in ~6 minutes.
**Uncordon is not tidying up — it is what re-enables redundancy.** Full runbook + post-maintenance
checklist in `infra/PROD-STANDUP.md` §Node maintenance, including why `drain` can never complete here
(instance-manager PDBs at 0 allowed disruptions; at 3 nodes/3 replicas replica eviction has nowhere to
go, which is structural, not a setting).
### FOUR BUGS OF ONE SHAPE — *a thing that looks applied and isn't*
Worth naming as a class, because it has now appeared four times in two days:
1. **Kyverno's own CRDs** — `crds.install: false`, nothing else installed them; pods crash-looped 55×.
2. **CDI StorageProfiles** — CR and its dependent resource in the same Flux pass; the dry-run aborts
the tier, so the CR never applies and its CRD never appears. *Repaired in the graph* (`765ad03`).
3. **The placeholder guard** — a `TBD-*` prefix glob stopped matching when the value it guards changed
*in a different file*; `resume` would have enabled velero against a nonexistent host. Now tested
(`a984442`).
4. **PolicyException** — the CRD is installed but every controller runs
`--enablePolicyException=false`. An exception would apply cleanly through Flux and be **silently
ignored**. Verified live on prod.
Two more of the same family: a coverage check that passed when perturbed (asked a question always
satisfiable), and `ci/touched-requirements.sh` having **no `bootstrap/*` entry**, which scoped the L0
run away from the very check guarding the placeholder class. Both fixed.
**The rule:** dev's age hides cold-start defects. Anything that only runs on a fresh cluster has never
been exercised on dev, and prod is the first honest test. And: *a guard keyed on the shape of a value
that lives in another file needs a test tying the two together.*
### Kyverno blocking CDI — fixed by SATISFYING the policy, not exempting it
Prod's UniFi VM had no disk: Kyverno denied CDI's generated `importer-*` pod for missing the
`auth-mode` / `egress-class` labels, which CDI cannot set. Fixed with a **mutate** policy that adds
them when the requester is ServiceAccount `cdi/cdi-sa` — identity from AdmissionReview userInfo, **not
a name prefix** (a prefix is attacker-choosable; the test proves it with a forged
`importer-prime-forged-by-an-app` fixture that is still denied). Two-way proof: same pod, different
requester, opposite outcomes. Kyverno L0 17 → 29 tests.
Rejected `exclude` scoped to the same SA because any userInfo match forces `background: false`, which
would drop background scanning of R-NET-05/R-IDP-02 for **all existing pods** to fix one pod class.
### Conformance 82.4% → 88.2%
45/51 scaffolded, 0 safety-critical gaps. Six L2 tests made environment-agnostic (they derive
`BASE_DOMAIN`/`GATEWAY_VIP` from the cluster they run against, so they cannot drift); R-TLS-02,
R-ENV-01 and R-ENV-03 covered — the last two matter because the Phase-7 entry-gate note recorded
R-ENV-01/02/03 as uncovered while prod provisioning was proceeding.
### STAGED FOR ONE PUSH — `prod/deliver-fixes`
Prod reconciles bootstrap-Gitea `main@c8c1d29` and **cannot take the working branch** — that carries
the DNS inversion, which would move prod to the apex and collide with dev. `prod/deliver-fixes` is
`c8c1d29` + the CDI graph fix + the Kyverno mutate policy: a clean fast-forward, verified free of any
cluster-vars/externaldns/overlay change, prod's `BASE_DOMAIN` untouched, render checked. **Not pushed
— that changes what a live cluster reconciles.**
### Waiting on the operator (deliberately skipped)
- **R2 credentials.** Two token values; the account id is already committed in
`infra/tofu/backend.r2.hcl`. `infra/BACKUP-R2.md` is the procedure. **Prod has no backup coverage.**
- **`enableCertificateOwnerRef`** — R-TLS-02's "revoked" clause is unmet; both clusters' TLS Secrets
have zero ownerReferences. Not flipped because the wildcard Certificate lives under a `prune: true`
tier, so a transient prune would delete the serving Secret and reissuance is capped at 5/week.
- **Node timezone** — authored (`Etc/UTC`, matching dev), `--check` confirms the drift, **not applied**:
a live clock change during storage resync is not an unattended action.
- **Database HA** — all three CNPG clusters are `instances: 1` and all three primaries are on prod-1.
Losing that node takes Keycloak, Nextcloud and Semaphore together. `instances: 2` spends resources.
- **The apex flip** is also the legacy-prod 443 cutover; §10a sequence P does not cover the SOHO NAT.
- **R-STATE-04** stays a gap: `bulk` is a non-provisioning stub pending **OQ-2**.
- Orphaned `prime-be3f9d1c-…` 40 GiB scratch PVC from the blocked imports — operator cleanup.

**Rollback** is the same command with `FLUX_INSTALL_PLAIN=1 bash bootstrap/flux/bootstrap.sh`, or
simply `flux install --namespace=flux-system --components-extra=…` (drops the arg back off).
## The CRD pre-apply step (`preapply-crds.sh`) — why bootstrap has to do this
`platform/kyverno/admission/helmrelease.yaml` sets `crds: {install: false}`. That is correct and must
stay: the Kyverno CRD bundle is **5,636,155 bytes across 22 CRDs** at chart 3.9.0 (measured with
`helm template … --include-crds`, 2026-09-04), so Helm's client-side apply hits kubectl's 256 KiB
`last-applied-configuration` annotation limit — `metadata.annotations: Too long` — which stalls the
HelmRelease and blocks `platform` plus every tier that `dependsOn` it.
The part that was never automated: **with CRD install off, nothing installs the CRDs.** Kyverno's
Deployments start, its API types do not exist, `platform` never reaches Ready. Dev has them only
because somebody once ran the command in a shell. `preapply-crds.sh` is that command, in git:
```
helm template <chart> --repo <url> --version <constraint> --include-crds --set crds.install=true
| yq 'select(.kind == "CustomResourceDefinition")'
| kubectl apply --server-side --force-conflicts
```
- **Version derivation, not a second pin.** `chart`, `version`, `namespace` and the repo `url` are
read out of the HelmRelease/HelmRepository pair with `yq`. `spec.chart.spec.version` is a semver
**constraint** (`3.9.x`), and `helm template --version` accepts the same constraint syntax
helm-controller resolves — so the rendered CRDs are the ones Flux will install, and a Renovate bump
of that one line carries this step with it. There is nothing here that can drift.
- **CRDs only.** Piping the *whole* `helm template` output into kubectl (the by-hand command in the
HelmRelease comment) would create Deployments/webhooks outside Helm's ownership and then fight the
HelmRelease over field managers. The `yq` filter is load-bearing.
- **Idempotent.** Server-side apply is an upsert; `--force-conflicts` adopts the fields dev's
hand-applied CRDs left owned by `kubectl-client-side-apply`. Re-running prints
`serverside-applied` and exits 0.
- **Cannot degrade to a no-op.** Three guards: every derived coordinate must be non-empty and not
`null`; the rendered CRD count must be `> 0` (an empty stream would otherwise `apply` cleanly and
exit 0 — the exact silent-success bug this repo keeps hitting); and after the apply every CRD is
waited on for `condition=Established`. There is **no skip flag** on purpose.
- **Environment-agnostic (R-ENV-02).** It names no environment and takes no overlay input — it reads
repo files and acts on `$KUBECONFIG`. Dev and prod run the identical step.
Standalone use (an already-bootstrapped cluster whose `platform` is blocked on the missing CRDs):
```bash
# inside infra/devcontainer, KUBECONFIG pointed at the target cluster

# WHY THIS EXISTS
#
# platform/kyverno/admission/helmrelease.yaml sets `crds: {install: false}`. That is deliberate:
# the Kyverno CRD bundle is ~5.6 MiB, far past kubectl's 256 KiB last-applied-configuration
# annotation limit, so Helm's client-side apply fails with "metadata.annotations: Too long" and
# STALLS the HelmRelease — which blocks the `platform` Kustomization and every tier that dependsOn
# it (the kps-cascade failure mode; see the HelmRelease's own comment).
#
# The consequence nobody automated: with CRD install off, NOTHING installs those CRDs. Kyverno's
# Deployments come up but its API types do not exist, so `platform` never goes Ready on a cold
# cluster. The dev cluster only has them because they were once applied BY HAND — exactly the
# undocumented manual step this repo exists to eliminate. This script is that step, in git,
# version-derived and idempotent.
#
# HOW THE VERSION IS DERIVED (there is deliberately NO second copy of it)
#
# Everything comes out of the HelmRelease/HelmRepository pair that Flux itself reconciles:
#
# chart name spec.chart.spec.chart (HelmRelease)
# chart version spec.chart.spec.version (HelmRelease) e.g. "3.9.x"
# chart repo url spec.url (HelmRepository)
# namespace metadata.namespace (HelmRelease)
#
# The version is a semver CONSTRAINT, not a fixed tag. `helm template --version` accepts the same
# constraint syntax Flux's helm-controller resolves (both use Masterminds/semver), so passing it
# through UNCHANGED renders the very chart version Flux will install. Renovate bumps one line in
# one file and this step follows automatically — it cannot drift, because there is nothing here to
# drift from.
#
# WHY ONLY THE CRD DOCUMENTS ARE APPLIED
#
# The by-hand command recorded in the HelmRelease comment piped the WHOLE `helm template` output
# into kubectl. Do not do that: it would create Deployments/Services/webhooks outside Helm's
# ownership, which then fight the HelmRelease over field managers and leave orphans behind. We
# filter to `kind: CustomResourceDefinition` and apply nothing else. Values are the chart DEFAULTS
# (plus an explicit crds.install=true) — NOT the repo's values, which switch CRD rendering off.
#
# IDEMPOTENCY
#
# `kubectl apply --server-side --force-conflicts` is a declarative upsert: the first run creates,
# every later run reports "serverside-applied" and exits 0, and field ownership is taken from
# whatever previously wrote those objects (that is what --force-conflicts is for — it resolves the
# hand-applied dev CRDs' `kubectl-client-side-apply` manager without a human deciding anything).
# Server-side apply does not write the last-applied annotation, which is the whole reason the
# 5.6 MiB bundle can be applied at all.
#
# LOUD FAILURE (this script must never degrade to a successful no-op)
#
# `set -euo pipefail`, plus three explicit guards, because a silent skip here reproduces the exact
# class of bug this repo has been bitten by more than once:
# 1. every derived coordinate must be non-empty and not "null" — a moved YAML path fails here;
# 2. the rendered CRD count must be > 0 — if a future chart moves/renames its CRD templates the
# filter would match nothing and `kubectl apply` on an empty stream EXITS 0. Guarded;
# 3. after applying, every CRD is waited on for condition=Established — so "applied" is proven
# to mean "the API type exists", not merely "kubectl returned 0".

# ======================================================================= s3check plumbing
# WHY THIS IS THIS BIG. The previous version of `s3check` curl'd /minio/health/live and reported
# REACHABLE. That probe could not pass against Cloudflare R2 (no such path), and reachability is not
# the property anyone cares about: a reachable endpoint with a wrong key, a missing bucket, or R2's
# checksum rejection still yields a velero tier that reports Ready while NO backup exists. What must
# be proven is the write path Velero and CNPG-barman actually use, with the credentials they actually
# hold, from the network position they actually occupy.
# Pinned. The AWS CLI is a deliberate choice over `minio/mc`:
# - it prints the S3 ERROR CODE (NoSuchBucket / AccessDenied / InvalidAccessKeyId / InvalidArgument),
# so a failure can be NAMED and turned into a fix instead of guessed at from an HTTP status;
# - it exposes the FLEXIBLE-CHECKSUM behaviour that is the R2 trap
# (AWS_REQUEST_CHECKSUM_CALCULATION), so the trap can be reproduced on purpose here instead of
# discovered by a silently-failing backup at 03:00;
# - its image carries bash + coreutils. `minio/mc` ships no sed/awk/diff — that minimalism has
# already broken one probe in this repo — and it cannot be made to send the checksum headers, so
# it cannot test for the trap at all.

### Second-order CRDs need a THIRD pass (`platform-config-cdi`, added 2026-09-05)
The controllers/configs split (`platform` → `platform-config`) assumes a CRD is registered by the
controller **install**. CDI breaks that: `cdi-operator.yaml` registers only `cdis.cdi.kubevirt.io`,
and cdi-operator creates `storageprofiles` / `datavolumes` / `datasources` **only after it has
reconciled the `CDI` CR**. Since kustomize-controller server-side **dry-runs every object in a pass
before applying any of them**, having the `CDI` CR and the CDI `StorageProfile`s in one pass was a
**deadlock, not a race**: unknown kind → pass aborts → CR never applied → CRD never created →
`platform-config` can never converge → every tier below it blocked. Invisible on dev (its CDI CRDs
have existed for months); it cost 12h on prod's cold start.
So there is a third tier, `platform-config-cdi` (`./platform-config-cdi`, `dependsOn:
platform-config`), and a rule:
> A CR belongs in `platform-config-cdi`, not `platform-config`, when the CRD it needs is created by a
> **controller at runtime** rather than by a manifest in git.
`apps-vms` `dependsOn` it as well as `platform-config`, because CDI reads
`StorageProfile/longhorn-vm` at DataVolume **provisioning** time — a VM disk provisioned before that
profile exists is stamped RWO/Filesystem and is permanently not live-migratable.
Wave 0 `dependsOn` `platform-config` (transitively `platform`) so CNI/storage/TLS/DNS/gateway
exist before any workload reconciles. The app tier is split into dependency-ordered WAVES

# Both environments are now NAMESPACED SYMMETRICALLY, which was not possible an hour ago and is

# kustomize-controller server-side DRY-RUNS EVERY object before applying ANY of them, and
# `storageprofiles.cdi.kubevirt.io` does not exist until cdi-operator has reconciled that `CDI` CR.
# So the unknown kind aborted the whole tier → the CR was never applied → the CRD was never created →
# platform-config could NEVER converge and every tier below it stayed blocked. Not a race: a
# deadlock. cdi-operator was Available for 12h on prod with no CR. Invisible on dev (its CDI CRDs
# have existed for months), FATAL on any cold cluster. See DECISIONS-LOG 2026-09-05.

# `bootstrap/standup.sh crds` pre-applies the `CDI` CR to break it by hand. That is a WORKAROUND and
# stays as belt-and-braces for clusters already wedged; THIS Kustomization is the fix that makes the
# graph order itself, so a cold cluster needs no human in the loop.
#
# THE ORDERING GUARANTEE, precisely: `dependsOn` is REVISION-gated, not merely Ready-gated (verified
# against kustomize-controller v1.4.0 `kustomization_controller.go :: checkDependencies`, our
# version): sharing a GitRepository with the dependency, this Kustomization cannot reconcile revision
# N until `platform-config` has APPLIED revision N — and, because platform-config runs `wait: true`,
# not until the `CDI` CR it applied is HEALTHY. cdi-operator creates the remaining CDI CRDs as part of
# reaching that state, so by the time this tier's first dry-run runs, `StorageProfile` is a known
# kind. One edge, no pre-apply.
#
# WHY NOT just move the CDI CR earlier, into `platform`? Because `platform` is the tier the CNI gates

# cache is one retryInterval. Keep it short.
retryInterval: 2m
# 2m is ample: this tier applies two tiny cluster-scoped CRs. There is no workload to roll out, no

# CANNOT STALL: `StorageProfile`'s status type (CDI v1beta1 StorageProfileStatus: storageClass,

# `conditions` and NO `observedGeneration`, so kstatus's generic path reports it Current the moment
# it is applied. `wait: true` therefore adds a Ready condition without adding a way to hang — which
# is why it is safe to let `apps-vms` gate on it (contrast the headlamp gating stall).
# If a resource that CAN be unhealthy is ever added to ./platform-config-cdi, re-derive this:
# `apps-vms` waits on it.
#
# WHAT IT DOES NOT PROVE (honest gap): CDI reads the profile's **status**, not its spec, when it
# provisions a claim (status.claimPropertySets / status.cloneStrategy), and CDI's
# storageprofile-controller computes that status from our spec override plus inference. So Ready
# here means "the spec override is accepted by the API server", not "CDI has folded it into
# status". That reconcile is a watch-triggered round-trip of seconds, and the dependency requeue
# below it is ~30s, so a DataVolume cannot realistically beat it — but it is a timing argument, not
# a guarantee, and no `wait` setting can turn it into one (there is no condition to wait on).

# `kustomize.toolkit.fluxcd.io/name=platform-config-cdi` label).
#
# Why that is acceptable here — and it is NOT the platform/cilium case:
# * Neither object is the sole (or any) declarer of a shared object. No Namespace, no ConfigMap,
# nothing else in the repo declares a StorageProfile. The stale set is exactly two
# cluster-scoped CDI CRs.
# * The objects do not actually go missing: CDI's storageprofile-controller creates a
# StorageProfile per StorageClass and recreates a deleted one, with an EMPTY `.spec` and
# inferred `.status`. So the transient is "our .spec overrides are absent", not "the object is
# absent".
# * A StorageProfile is read at DataVolume/PVC PROVISIONING and CLONE time only. Existing PVCs,
# existing DataVolumes and running VMs do not consult it again, so nothing already provisioned
# is disturbed and no data path is touched.
# * The only exposure is a DataVolume/clone STARTED inside the window: it would clone by `copy`
# instead of `snapshot`, and on `longhorn-vm` be stamped RWO/Filesystem instead of RWX/Block —
# permanently non-live-migratable for that disk. Flux cannot cause that, because `apps-vms` now
# dependsOn THIS tier (clusters/base/apps-vms.yaml), so no Flux-managed DataVolume can be
# created while the overrides are absent. A human running `virtctl`/`kubectl` in that minute
# could.
#
# PRECONDITION THE OPERATOR MUST CHECK, because it is what bounds the window: the recreate cannot
# happen until `platform-config` is Ready, and platform-config runs `wait: true` over the whole
# config tier (ClusterIssuers, wildcard Certificate, Gateway, Keycloak, CNPG, KubeVirt, CDI…). On a
# healthy cluster that is seconds and the window is ~30-60s (kustomize-controller's
# --requeue-dependency default is 30s). If platform-config is NOT Ready when this merges, the
# StorageProfiles are pruned and stay at CDI defaults until it recovers. So:
# `flux get kustomization platform-config` must be Ready BEFORE merging.
# If it is not, do the two-step the cilium move used instead: merge with `platform-config.prune`
# temporarily set to `false` (the objects are then dropped from its inventory but NOT deleted, and
# this tier ADOPTS them with zero window), verify the ownership label transferred, then restore
# `prune: true` in a second commit.

# which changes WHY the blocker holds but not THAT it holds:
# 1. SELF-HOSTING CIRCULARITY — still true, and now the only reason. The Gitea this repo is

# OPERATOR DECISION 2026-09-04, superseding the interim split committed earlier the same day

#
# dev -> dev.home.keithjackson.dev (dev carries the label; clusters/dev)
# prod -> home.keithjackson.dev (THE APEX — this knob)
#
# There is NO `prod.` label and NO CNAME layer. `<svc>.home.keithjackson.dev` is prod's REAL

#
# BACKGROUND — WHY THE SUFFIXES HAD TO SPLIT AT ALL. Until 2026-09-04 every hostname was
# HARDCODED to home.keithjackson.dev in the base manifests, so prod was authored to serve the
# EXACT SAME public names as the live dev cluster out of the SAME Cloudflare zone. Two
# consequences, one of which already happened:
# PROD SERVES ITS OWN SUBDOMAIN. Until 2026-09-04 every hostname was HARDCODED to
# home.keithjackson.dev in the base manifests, so prod was authored to serve the EXACT SAME
# public names as the live dev cluster out of the SAME Cloudflare zone. Two consequences, one
# of which already happened:
# 1. HAPPENED: prod's external-dns (policy: sync, owner id `default` — the same implicit
# default dev had) concluded it owned dev's records and DELETED EVERY ONE of them.
# 2. QUEUED BEHIND IT: platform-config would have requested a `*.home.keithjackson.dev`
# wildcard from letsencrypt-prod for a cert dev already holds, and both clusters would
# have raced each other's `_acme-challenge` TXT records on that one zone.
# Moving prod to its own suffix dissolves both: the two clusters can no longer name the same
# record. This is what makes ACME_CLUSTER_ISSUER: letsencrypt-prod above safe here.

# (c) dev's old `*.home.keithjackson.dev` cert/Certificate is released, because prod ordering
# that same name set while dev's still exists counts against LE's duplicate-certificate
# limit (5 per week per identical name set).

#
# THERE IS DELIBERATELY NO `S3_BACKUP_ENDPOINT` OP HERE, and that is a reversal of the rule
# stated at the top of this overlay ("an OMITTED op means prod silently inherits a dev
# address"). That rule exists because base defaults are dev's LAN addresses. R2 is not one: it
# is a single shared, environment-independent endpoint, so under R-ENV-02 it belongs in base and
# overriding it with an identical value would only create two places to change on a rotation —
# the exact drift this repo has been bitten by before. Isolation does NOT come from the
# endpoint; it comes from the two path knobs below.
#
# WHY R2 AND NOT THE MinIO the operator first named: prod is on the SOHO network
# 192.168.2.0/24, which is pfSense's WAN, while the MinIO sits inside pfSense's LAN
# 192.168.1.0/24. Measured from a pod INSIDE prod (the workstation proves nothing about pod
# egress): `curl http://192.168.1.9:9000/minio/health/live` → connection timed out after 15s.
# Reaching it would need a WAN→LAN rule that does not exist. R2 needs no firewall change, and
# unlike that MinIO — which runs on the same Proxmox host as dev's VMs — it is genuinely
# off-site. Verify prod can reach the new endpoint before resuming velero:
# bootstrap/standup.sh ... --s3-endpoint <the R2 endpoint> s3check
#
# THE PATH KNOBS ARE WHAT MAKE ONE SHARED BUCKET SAFE. Nothing about the paths was
# per-environment before 2026-09-05: Velero used one unprefixed bucket, and every CNPG Cluster
# used `s3://cnpg` with serverName defaulting to the CLUSTER NAME — and both environments have
# keycloak-db / nextcloud-db / semaphore-db. Without these knobs prod would (a) adopt and

# ---------------------------------------------------------- scaffold-marker detection
# WHY THIS IS NOT A WHOLE-FILE `"TODO" in text`
# ---------------------------------------------------
# It used to be, and that mis-reported a SAFETY-CRITICAL requirement. A test whose SUBJECT
# is placeholder detection has to name the idioms it hunts for:
# `l0-static/placeholder-guard-coupling/check.sh` carries
# `SEED = ["TBD", "TODO", "FIXME", "PLACEHOLDER", ...]` — its detection vocabulary, as data.
# A whole-file substring test read that as the test declaring itself unfinished, classified
# a 32-assertion executable check as a scaffold, raised a permanent `--strict` annotation
# conflict, and (because the same file is tagged R-STATE-03) reported R-STATE-03 as
# `exec=1 scaffold=1`. A previous engineer worked around it by rewording prose.
#
# The rule below is derived from the corpus (43 tests), not invented. Every genuine
# scaffold in this tree — `l2-behavioral/onboarding-completeness`, `l3-fault-injection/
# alerting`, `l3-fault-injection/gitops-drift`, and no others — declares itself in BOTH of
# two structural positions, and no executable test does either:
#
# 1. a `# STATUS: ... scaffold` line in the file's documentation header. This is the
# repo's DEDICATED declaration slot (tests/README.md): 3 of 43 tests say
# `STATUS: scaffold` and they are exactly the three scaffolds; 19 others declare
# `STATUS: EXECUTABLE` / `IMPLEMENTED` / `RUNNABLE`; the rest declare nothing.
# 2. a TODO/FIXME marker in the BODY that CARRIES A MESSAGE — `echo "TODO: assert PVC
# bound ..."`, `TODO(T-4.1): hermetic SMTP capture sink`. A marker that carries a
# message is a note about work that is missing. A marker that is the ENTIRE content of
# a quoted literal (`"TODO",` in a vocabulary list) carries no message: it is the
# marker as a *datum*, which is what a placeholder DETECTOR necessarily contains.
#
# Both are still evaluated over the body of `chainsaw-test.yaml` AND of any
# `render-check.sh` / `check.sh`, and either one still OUTRANKS an
# `executable: "true"` annotation (see classify_test) — the invariant that an annotation
# must never outrank the body is unchanged. Ambiguity still only ever DOWNGRADES: an
# unrecognised marker shape, a marker in body code outside a quoted literal, or a marker
# carrying any trailing text all classify as scaffold.
#
# KNOWN, ACCEPTED IMPRECISION (stated rather than hidden): a test that embeds a marker with
# text attached but as data — e.g. `re.compile(r"TODO|FIXME")`, or a single string holding
# several idioms — is still called a scaffold. That is the conservative direction, and the
# author's remedy is the same structural discipline the corpus already uses: keep each
# idiom a standalone literal in a list.
# Vocabulary: only the idioms that DECLARE unfinished work. Deliberately excludes `TBD`,
# `PLACEHOLDER`, `XXX`, `REPLACE-ME` — tests in this tree legitimately carry those in
# executable code as data (`l0-static/egress-paths-selected-by-rules/check.sh` compares
# authored values against `"TBD"`; `l0-static/no-plaintext-secrets/check.sh` matches
# `placeholder.*`), and none of them is used here to mark a placeholder body.
# Case-insensitive: no English word contains either token, and the corpus carries no
# lower-case occurrence, so folding case only ever ADDS detection (`echo "todo: ..."`).
_MARKER_RE = re.compile(r"\b(?:TODO|FIXME)\b", re.I)
# The dedicated declaration slot, on a comment line, case-insensitive. The declared state
# must be the FIRST token after `STATUS:` — a `STATUS:` line declares exactly one state,

bindings:
- name: baseDomain
value: (x_k8s_get($client, 'v1', 'ConfigMap', 'flux-system', 'cluster-vars').data.BASE_DOMAIN)
```
Declare it at **test level** (step `outputs`/`bindings` are step-scoped), then consume it:
`($baseDomain)` for a pod `env:` value, `(join('.', ['myhost', $baseDomain]))` where a
full hostname is needed — including inside a `fixtures/*.yaml` applied with `apply: file:`,
which chainsaw templates with the same bindings. Prefer reading the *actual* observed value
over restating a range (e.g. assert the DNS answer equals `GATEWAY_VIP`, or equals the LB IP
the Service was assigned) — it is both stricter and environment-independent. Never take the
environment from a CLI flag or an exported variable: a flag someone forgets is how a suite
ends up silently asserting the other cluster's expectations. L1 goldens are the one
exception: they are rendering fixtures and carry the literal `${BASE_DOMAIN}` token.
### How a scaffold declares itself (and how `status.py` tells one from a verifier)
Scaffolds in this tree carry `TODO(T-x.y)` markers where a fixture/assertion lands as a
later roadmap phase delivers the capability under test. `lib/status.py` treats such a
marker — in the `chainsaw-test.yaml`, in `render-check.sh`, or in `check.sh` — as
outranking any `conformance.home.k3s/executable: "true"` annotation, so a placeholder body
can never be reported as an executable test.
later roadmap phase delivers the capability under test. `lib/status.py` classifies each
test EXECUTABLE or SCAFFOLD from the test's own files — `chainsaw-test.yaml`,
`render-check.sh`, `check.sh` — and either signal below **outranks**
`conformance.home.k3s/executable: "true"`, so a placeholder body can never be reported as
an executable test. Declare a scaffold in **both** positions:
1. **`# STATUS: scaffold — <what is missing>`** in the file's header comment block. The
declared state must be the first token after `STATUS:` (executable tests say
`# STATUS: EXECUTABLE` / `IMPLEMENTED` / `RUNNABLE`).
2. **A `TODO`/`FIXME` marker carrying a message, in the body** — the file from its first
non-comment line onward. `echo "TODO(T-4.2): inject a fault to fire a rule"`,
or an inline comment on a missing fixture:
`file: fixtures/smtp-sink.yaml # TODO(T-4.1): hermetic SMTP capture sink`.
What is **not** a scaffold marker, and why the distinction is load-bearing: a marker
mentioned in the **header prose** (the Given/When/Then and the mandatory "what this does
NOT prove" list), and a marker that is the **entire content of a quoted literal** — a
placeholder *detector*'s own vocabulary, e.g. `SEED = ["TBD", "TODO", "FIXME", ...]` in
`l0-static/placeholder-guard-coupling/check.sh`. A whole-file `"TODO" in text` test used to
classify that 32-assertion check as a scaffold and, through it, report the safety-critical
R-STATE-03 as `exec=1 scaffold=1`. If your check must hold a marker as data, keep each
idiom a **standalone quoted literal in a list**; a marker with text attached (a regex
alternation, several idioms in one string) still classifies as a scaffold, because
ambiguity here only ever downgrades.

# Spec: docs/00 R-SEC-03 ("All the above properties MUST be demonstrable/auditable (an

# made concrete by docs/07 §"Auditability requirements (R-SEC-03) — what an operator

# check), Kill-switch (fault-injection test), TLS (cert status + external check),
# Backups (DR drill) — "These proofs are part of the platform acceptance suite, not
# one-time checks", with the acceptance gate "The five auditability proofs above can
# be produced on demand."
#
# HOW THIS AVOIDS BEING A TAUTOLOGY (the whole design question for a meta-requirement)
# -----------------------------------------------------------------------------------
# "A test exists for R-NET-01, therefore isolation is auditable" would pass in any suite that
# compiles and would keep passing while every proof rotted into a scaffold. Four distinct
# failure modes are asserted instead, each by DRIVING the real machinery:
# (a) each of the five proofs has an EXECUTABLE test — not a placeholder scaffold — at the layer
# the spec's own words require (fault injection / a DR drill => L3), taken from
# lib/status.py's own verdict so this check cannot disagree with the status report;
# (b) the proofs are PRODUCIBLE by the documented command: `run.sh --requirements <the five>`
# must resolve to real test dirs AND pass the merge gate's coverage assertion;
# (c) each Chainsaw-layer proof declares a PASS SENTINEL that lib/record_run.py can
# attribute — a proof that passes but records nothing leaves the operator with a green
# terminal and no evidence;
# (d) the evidence chain REFUSES FORGERIES: this check mounts two of its own against the
# real tools — a green JUnit for a real proof test whose log holds only that test's SKIP
# token, and a ledger row claiming `proven` at the repository's ROOT commit — and
# requires record_run.py to report not-proven and status.py to report `stale-proof`. It
# also drives `record_run.py --selftest` and `status.py --selftest`, which NOTHING in
# ci/ or run.sh ran before this test existed.
# The five proofs are not hand-listed where the spec can be read: when the read-only spec repo
# is mounted, docs/07's bullet labels are parsed and must match this check's mapping exactly,
# so a sixth proof added to the spec fails here instead of being silently unverified.
#
# WHY L0: every clause is a property of the repository and its own tooling, needs no cluster,
# and belongs in the merge gate — an audit chain is worth having only if it is intact BEFORE
# anyone needs it.
#
# GIVEN the repository as git tracks it (plus the read-only spec repo when mounted),
# WHEN lib/status.py, lib/common.sh's requirement resolver, run.sh's coverage gate,
# lib/record_run.py's sentinel parser and both evidence tools' self-tests are DRIVEN,
# and two synthetic forgeries are presented to them,
# THEN each of docs/07's five proofs maps to an executable test at the required layer, the
# documented one-command invocation selects and asserts them, each is capturable as a
# ledger row, and neither a self-skip nor a stale row can be recorded as proof.
#
# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git tree + the harness's
# own stdlib tooling; no cluster, no network); conformance/run.sh --layer l0 and ci/l0.sh run
# it directly, and this Chainsaw Test wraps the SAME script.
#
# WHAT THIS TEST FIXED WHILE BEING WRITTEN (recorded, not hidden): three of the tests that ARE
# the automated half of docs/07's isolation and TLS proofs — l2-behavioral/default-deny,
# l2-behavioral/trusted-tls and l2-behavioral/gateway-ingress-reachable — declared NO pass
# sentinel, so lib/record_run.py could never record them as proven and those two audit proofs
# were structurally unrecordable. Each now ends with a proof-of-pass sentinel step. The
# assertion here was NOT relaxed to accommodate them (R-TEST-06).
#
# KNOWN, DELIBERATE GAPS (enumerated in check.sh's header; this test claims none of them):
# * That the five proofs PASS. This asserts they are present, strong, runnable by one
# command, capturable, and that the chain refuses forgeries — not that isolation holds
# today (R-NET-01's test) or that the restore works (R-STATE-03's).
# * HUBBLE. docs/07 names Hubble flow logs as part of the isolation proof; no test in this
# suite queries Hubble. Only the denied-probe half is automated — a real, named gap.
# * LEDGER COMPLETENESS OVER TIME. Nothing offline can prove a row was never removed; that
# would need signed history.
# * R-SEC-03's wording is broader than docs/07's five bullets. Suite-wide coverage of every
# requirement is R-TEST-01/04's claim (tests/meta/harness-selfcheck) and is deliberately
# not re-asserted here.

#
# HOW A META-REQUIREMENT IS TESTED WITHOUT BECOMING A TAUTOLOGY
# ------------------------------------------------------------
# The trap is obvious and this check is built to avoid it: "a test exists for R-NET-01,
# therefore isolation is auditable" is true of any suite that compiles, proves nothing, and
# would keep passing while every proof rotted into a scaffold. Four separate failure modes
# have to be caught for "an operator can PROVE it" to mean anything, and each one is asserted
# by DRIVING the real machinery rather than by reading files:
#
# (a) THE PROOF EXISTS, AT THE RIGHT STRENGTH. Each of the five named proofs maps to a
# requirement that must have an EXECUTABLE verifying test — not a placeholder scaffold — and,
# where the spec's own words name fault injection ("with VPN down"; "a DR drill"), an
# executable L3 test specifically. Executable-vs-scaffold is not re-derived here: this
# check RUNS lib/status.py and reads its verdict, so it cannot disagree with the
# repository's own status report.
# (b) THE PROOF IS PRODUCIBLE ON DEMAND, BY THE DOCUMENTED COMMAND. `run.sh
# --requirements <the five IDs>` must resolve to a non-empty test set and must ASSERT
# their coverage (that flag is the merge gate's own path: it passes --require to
# coverage.py). This check drives run.sh itself, so if the resolver, the labels or the
# gate wiring break, R-SEC-03 fails.
# (c) THE PROOF IS CAPTURABLE. A test that passes but records nothing leaves an operator
# with a green terminal and no evidence. For each Chainsaw-layer proof, the test must
# declare a PASS SENTINEL that lib/record_run.py can actually attribute — computed with
# record_run.py's OWN parser, so deleting a test's sentinel makes this check fail
# instead of silently making the requirement unprovable.
# (d) THE EVIDENCE CANNOT BE FORGED, AND IS NOT HONOURED WHEN STALE. This is the clause
# that makes the check bite. Two INDEPENDENT forgery attempts are mounted against the
# real tools, in a throwaway directory:
# * a Chainsaw run in which the JUnit says a real proof test PASSED while the run log
# carries only that test's SKIP token — the exact shape of a self-skipping L2/L3
# test. record_run.py must refuse to call it `proven`.
# * a ledger row claiming `proven` at a commit that PREDATES the requirement's
# implementing code — status.py must degrade it to `stale-proof`, never green.
# Both tools' own built-in self-tests (`--selftest`) are also driven, because nothing
# in ci/ or run.sh runs them today: the guards that keep a skip from becoming a proof
# were themselves unexercised in the merge gate until this check.
#
# The FIVE PROOFS ARE NOT HAND-LISTED where the spec can be read: when the read-only spec
# repo is mounted, the bullet labels are parsed out of docs/07 and must match this check's
# mapping EXACTLY. Add a sixth proof to the spec and this check fails as unmapped rather
# than quietly ignoring it.
#
# WHY L0: every clause above is a property of the repository and its own tooling, provable
# offline, and it belongs in the merge gate — the point of an audit chain is that it is intact
# BEFORE anyone needs it. Nothing here needs a cluster, and nothing here would be more true
# with one.
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this check as claiming them):
# - THAT THE FIVE PROOFS PASS. This asserts the proofs are present, strong, runnable by one
# documented command, capturable as evidence, and that the evidence chain refuses
# forgeries. Whether isolation actually holds today is R-NET-01's test; whether the DR
# restore works is R-STATE-03's. R-SEC-03 is about the operator's ABILITY to produce the
# proof, which is what is asserted.
# - HUBBLE. docs/07 names "Hubble flow logs" as part of the isolation proof. No test in this
# suite queries Hubble, and this check does not pretend otherwise: it asserts the
# denied-probe half, which is the half that is automated. The Hubble half remains an
# operator-interactive capability — a real, named gap in R-SEC-03's coverage.
# - THE OPERATOR-FACING NARRATIVE. That a human can find and read the evidence (the status
# report's prose, the ledger's provenance fields) is a usability property, not a testable
# one.
# - LEDGER COMPLETENESS OVER TIME. The ledger is append-only by convention and by review;
# nothing here can prove a row was never removed from it (that would need signed history).
# - THAT THE PROOFS COVER "ALL THE ABOVE PROPERTIES". R-SEC-03's own wording is broader than
# the five bullets docs/07 enumerates. The five are what the spec made concrete and are
# what is asserted; suite-wide coverage of every requirement is R-TEST-01/04's claim,
# tested by tests/meta/harness-selfcheck, and is deliberately NOT re-asserted here.

# L0 STATIC — dev/test nodes are provisioned as code, end to end (R-ENV-01) [EXECUTABLE]
# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
# Spec: docs/00 R-ENV-01 ("dev/test MUST be provisioned as local KVMs via IaC:
# created, baselined, cluster-joined, and managed as code"); the four stages
# are enumerated in docs/02 §"Node lifecycle stages".
#
# WHY L0: R-ENV-01 is a requirement about HOW the dev nodes came to exist, and a live
# Node object cannot answer it — a node built by OpenTofu and one built by hand in a
# hypervisor UI are indistinguishable through the Kubernetes API. What is provable, with
# no cluster, is that a COMPLETE and EXECUTABLE provisioning path exists for all four
# stages and covers EVERY dev node. For the Ansible half that is proven by DRIVING the
# real toolchain offline (`--syntax-check`, `--list-hosts` — neither opens a connection
# to any node), not by reading files: a chain that does not resolve fails the check.
#
# ENVIRONMENT-AGNOSTIC: no hostname, address, prefix or node count appears in the test.
# The dev group names are read from the playbooks' own default host patterns, the node
# names are generated from the IaC module's prefix/count variables, and the two sets are
# compared against each other — so the assertion survives a rename or a resize.
#
# GIVEN the repository as git tracks it,
# WHEN the provisioning chain is parsed and (where offline execution is possible) driven,
# THEN the IaC module creates the dev nodes on a LOCAL KVM hypervisor (allowlisted
# provider — a cloud provider fails), from a for_each map rather than a count index,
# each with CPU/RAM/OS disk/dedicated Longhorn data disk/NIC/cloud-init seed; the
# node set it creates is EXACTLY the set Ansible manages; the baseline stage applies
# the package floor, kernel modules, sysctls, data-disk mount, swap-off and iscsid
# declaratively; one k3s role founds the cluster with --cluster-init and joins the
# rest with --server while disabling flannel/kube-proxy/traefik/servicelb at
# install; and site.yml's chain (baseline -> k3s -> Cilium -> verify -> Flux)
# resolves and targets every dev node at every stage.
#
# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git, PyYAML, and —
# where present — ansible-playbook in no-connection modes; no cluster, no network);
# conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this Chainsaw Test
# wraps the SAME script.
#
# KNOWN, DELIBERATE GAPS (enumerated in check.sh's header; this test claims none of them):
# * That the RUNNING dev VMs were created by this module — needs the OpenTofu state or
# hypervisor access, neither available offline.
# * `tofu validate` — needs `tofu init` (provider registry), i.e. network. The module is
# parsed, not evaluated; a network-allowed CI stage would close this.
# * "Never hand-edited on the box" (docs/02 stage 4's second half) — a live drift check.
# * REBUILD/re-converge (docs/02's own proof line) — exercised at L3 by
# tests/l3-fault-injection/node-loss (R-STATE-02).
# * docs/02 prose puts the baseline in cloud-init; the implementation moved it into the
# Ansible node_baseline role. R-ENV-01 requires the node to be "baselined ... as code",
# not that cloud-init be the tool, so the check asserts the STAGE and RECORDS the
# divergence rather than hiding it.

# L0 static check (offline, no cluster) — dev-nodes-provisioned-as-code
# Serves: R-ENV-01 ("dev/test MUST be provisioned as local KVMs via IaC: created,

# docs/00-vision-and-scope.md; the four stages are enumerated in

# 3. Cluster-join — Ansible installs/joins k3s with Cilium as CNI; disables
# k3s bundled flannel/traefik/servicelb/kube-proxy
# 4. Manage — GitOps-managed by Flux; node config changes are made via IaC
# and re-applied, never hand-edited on the box.)
#
# WHY L0 IS THE RIGHT LAYER, AND WHAT IT MEANS TO TEST THIS BEHAVIOURALLY
# ----------------------------------------------------------------------
# R-ENV-01 is a requirement about HOW the dev nodes come to exist. The live cluster
# cannot answer it: a Kubernetes node object looks identical whether it was built by
# OpenTofu or by hand in a hypervisor UI (there is no API field for "was I created by
# IaC"). What CAN be proven, with no cluster, is that a COMPLETE, EXECUTABLE
# provisioning path exists for all four stages and covers every dev node — and, for the
# Ansible half, that is proven by RUNNING the real toolchain in a no-connection mode
# (`--syntax-check`, `--list-hosts`) rather than by reading the files, so a chain that
# does not actually resolve fails here. The IaC half is asserted by parsing the module:
# `tofu init/validate` needs the provider registry, and L0 is offline by contract.
#
# GIVEN the repository as git tracks it,
# WHEN the provisioning chain is parsed and (where offline execution is possible)
# actually driven,
# THEN CREATE: the IaC module targets a LOCAL KVM hypervisor (every declared provider
# is a KVM-family hypervisor provider — no cloud provider may appear),
# instantiates its nodes from a for_each map (never a count index, so one
# node can be replaced without disturbing its siblings), and gives each
# node CPU, RAM, an OS disk, a DEDICATED Longhorn data disk, a NIC and a
# cloud-init seed carrying the login user + SSH key;
# AND the node set it creates is EXACTLY the dev node set Ansible manages —
# names derived from the module's own prefix/count, so no node can be
# hand-added to the inventory or hand-created in the hypervisor;
# BASELINE: a baseline stage exists as declarative Ansible (package floor, kernel
# modules persisted AND loaded, sysctls, the Longhorn data disk formatted
# and mounted, swap off, iscsid enabled), driven by variables with
# defaults rather than per-host special cases;
# JOIN: one role installs k3s for both roles of every node — `--cluster-init`
# on the primary, `--server` join on the secondaries — with flannel,
# kube-proxy, traefik and servicelb disabled AT INSTALL, and Cilium
# installed as the CNI afterwards;
# MANAGE: site.yml chains baseline -> k3s -> Cilium -> verify -> Flux bootstrap;
# `ansible-playbook --syntax-check` on that chain SUCCEEDS; and
# `--list-hosts` shows every one of those stages targeting EVERY dev
# node, so no node is outside the code path.
#
# ENVIRONMENT-AGNOSTIC: no hostname, address, prefix or node count is written down here.
# The dev group names come from the playbooks' own default host patterns, the node names
# from the IaC module's prefix/count variables, and the two sets are compared to each
# other. This check therefore keeps working when the estate is renamed or resized.
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
# - That the RUNNING dev VMs were in fact created by this module. Nothing offline can:
# it would need the OpenTofu state (a remote R2 backend + credentials) or hypervisor
# access. `tofu plan` against the live estate is the operator's own check.
# - That the module APPLIES cleanly. `tofu validate` needs `tofu init`, which downloads
# the provider from the registry; L0 is offline by contract, so the module is parsed,
# not evaluated. ci/lint.sh does not cover .tf either — a gap worth closing in CI
# with a network-allowed stage, not here.
# - "Never hand-edited on the box" (stage 4's second half) — a drift check against the
# live nodes, which is an operator/Ansible-check-mode exercise, not a repo property.
# - REBUILD/re-converge ("destroy a dev node VM and rebuild it", docs/02's own proof
# line) — that is exercised at L3 by tests/l3-fault-injection/node-loss (R-STATE-02).
# - That the baseline actually ran on a node (cluster/host state), and that the
# hypervisor is on the operator's own LAN rather than remote — "local" is asserted as
# "a KVM hypervisor provider driving a self-hosted endpoint variable", not as a
# network topology fact.
# - DEVIATION FROM docs/02 PROSE, ASSERTED DELIBERATELY: docs/02 describes stage 2 as
# cloud-init applying the OS baseline. The implementation moved the rich baseline into
# the Ansible `node_baseline` role (cloud-init keeps hostname/user/SSH/network),
# because Proxmox provisioning is API-only and a custom cloud-init snippet needs
# SSH/SFTP to the hypervisor. R-ENV-01's own wording requires the node to be
# "baselined ... as code", not that cloud-init be the tool, so this check asserts the
# STAGE, wherever it lives, and records the divergence rather than hiding it.

# L0 STATIC — two egress paths, and the rule set that selects between them (R-NET-04) [EXECUTABLE]
# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
# Spec: docs/00 R-NET-04 ("The platform MUST support **multiple egress paths** selected by
# routing rules ... realized as two paths — the local `internet` path and the
# in-cluster `vpn` path — not multi-ISP routing"), elaborated by docs/03 §"Egress

# the nodes themselves — egress the local/private WAN by default and **never** the
# VPN. Only services labeled `egress-class=vpn` are steered to the tunnel, and the
# kill-switch blackholes **only** that class."
#
# WHAT THIS ADDS OVER R-NET-05/07 (already covered, and NOT re-tagged here)
# ------------------------------------------------------------------------
# R-NET-05/07 are about a SERVICE — it declares a class, enforcement is outside it, the class
# flips via GitOps — and are proven by tests/l1-rendering/egress-class-render and
# tests/l2-behavioral/egress-class. R-NET-04 is about the PLATFORM's PATH SET and the RULES
# that select among them, which nothing else asserts:
# * exactly TWO paths, the same closed set in the schema, the admission policy and the
# renderer (a third value would be a path nothing routes; "multi-ISP" is out of scope);
# * selection is by a ROUTING RULE and the rule set is TOTAL AND DISJOINT — exactly one
# Cilium steering rule, selecting only `egress-class=vpn`, and on the gateway node one
# `ip rule` scoped to the tunnel address. NOTHING selects the `internet` class, because
# absence of a matching rule IS the default path;
# * the two paths COEXIST per DESTINATION: private space is excluded from the tunnel, so a
# vpn-class pod's cluster/LAN traffic still takes the local path;
# * the vpn path never becomes the DEFAULT — its default route lives in a dedicated routing
# table, `route-noexec` is set and a pushed `redirect-gateway` is ignored;
# * the kill-switch blackholes ONLY that class — the nft chain's policy is accept and every
# DROP is scoped to the vpn class's own source set/fwmark, so `internet` fails OPEN.
# (R-NET-06's opposite claim, that `vpn` fails CLOSED, is L3's vpn-killswitch.)
#
# WHY L0: every clause above is a statement about ALL rules — including rules that must be
# ABSENT (nothing selects the default path; no unscoped rule; no unqualified drop; no default
# route in the main table). A cluster can show which path two pods took; it cannot show that
# no third rule exists or that the vocabulary is closed.
#
# ENVIRONMENT-AGNOSTIC: no address appears. The private ranges the tunnel must exclude are
# checked as CONTAINMENT of the addresses each environment's own Flux overlay declares (pod
# CIDR, Gateway VIP, LB pool, API host), so a new environment on a different LAN is checked
# against its own values.
#
# GIVEN the repository as git tracks it,
# WHEN the egress vocabulary, every CiliumEgressGatewayPolicy, the gateway node's policy
# routing / OpenVPN / nftables templates, and every environment's overlay addresses are
# parsed and cross-checked,
# THEN there are exactly two paths with `internet` as the default; exactly one steering rule
# selects exactly the vpn class by label; the gateway is selected by node label with a
# named egress interface; all RFC1918 space and every address any environment assigns
# itself is excluded from the tunnel; the tunnel's default route and its fail-closed
# blackhole live only in a dedicated routing table behind a scoped `ip rule`; OpenVPN
# cannot take the main table; and no nftables DROP is unscoped.
#
# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git tree + PyYAML; no
# cluster, no network); conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this
# Chainsaw Test wraps the SAME script.
#
# KNOWN, DELIBERATE GAPS (enumerated in check.sh's header; this test claims none of them):
# * BEHAVIOUR. That an unlabelled pod really takes the WAN path is asserted at L2 by
# tests/l2-behavioral/egress-default-path (same requirement label); the two labelled
# classes are R-NET-05's L2 test; the kill-switch firing is R-NET-06's L3 test.
# * The RUNNING gateway node's routing tables / nftables ruleset. This reads the templates
# that generate them; a hand-added rule on the box is invisible here.
# * PHYSICAL MULTI-WAN's absence is NOT asserted — it is out of scope per OQ-1 and no
# honest repository signal distinguishes "one WAN, correctly" from "one WAN, by default".

# "**Physical multi-WAN (multi-ISP) is out of scope.** With a single WAN there is nothing

# route (`route-noexec` + policy routing), so the node's own traffic stays on the WAN —
# only what Cilium points at `tun0` uses the VPN."
#
# WHAT R-NET-04 ADDS OVER R-NET-05/07 (which are ALREADY covered) — READ THIS FIRST
# ---------------------------------------------------------------------------------
# R-NET-05/07 are about a SERVICE: it can declare its class, enforcement happens outside it,
# and the class can be flipped via GitOps. Those are proven by
# tests/l1-rendering/egress-class-render (the render) and tests/l2-behavioral/egress-class
# (two labelled pods observe two different public IPs, and a relabel re-routes the same pod).
# Re-tagging either of those with R-NET-04 would be a duplicate wearing a new label.
#
# R-NET-04 is about the PLATFORM's PATH SET and the RULES THAT SELECT AMONG THEM. Its
# distinctive content — none of which any existing test asserts — is:
#
# (1) THERE ARE EXACTLY TWO PATHS, and the same two everywhere. The class vocabulary is
# one closed set of two values agreed by the schema, the admission policy and the
# renderer. A third value appearing in one of them but not the others would be a path
# nothing routes (or a path nothing validates); "multi-ISP" reappearing as a third
# class would contradict OQ-1's resolution.
# (2) SELECTION IS BY A ROUTING RULE, and the rule set is TOTAL AND DISJOINT. The `vpn`
# path is entered only via rules that select the vpn class — a Cilium
# CiliumEgressGatewayPolicy pod-selector, and on the gateway node an `ip rule` scoped
# to the tunnel source address. Nothing selects the `internet` class, because
# "the `internet` path is simply the default route out": ABSENCE of a matching rule IS
# the default path. So an unlabelled pod, and an `internet`-class pod, take the WAN.
# (3) THE PATHS COEXIST — the choice is per-destination, not per-pod-lifetime. The vpn
# rule tunnels public destinations while EXCLUDING all private space, so a vpn-class
# pod's cluster/LAN traffic still takes the local path at the same time as its
# internet traffic takes the tunnel.
# (4) THE VPN PATH NEVER BECOMES THE DEFAULT. Split tunnel: the tunnel's default route
# lives in a DEDICATED routing table reached only through the scoped rule, the
# provider's pushed `redirect-gateway` is ignored, and `route-noexec` keeps OpenVPN
# from touching the main table. Otherwise there would be one path (the VPN), not two.
# (5) THE KILL-SWITCH BLACKHOLES ONLY THAT CLASS. The blackhole default is inside the
# dedicated table; the nftables chain's policy is ACCEPT and every DROP is qualified
# by the vpn class's own source set / fwmark. The `internet` path therefore fails
# OPEN and can never be blackholed. (R-NET-06's opposite claim — that `vpn` fails
# CLOSED — is proven at L3 by tests/l3-fault-injection/vpn-killswitch. This check
# asserts the OTHER direction, which that test does not.)
#
# WHY L0. Every clause above is a property of the RULE SET, i.e. of authored configuration:
# totality ("nothing selects the default path"), disjointness ("exactly one rule, selecting
# exactly one class"), and scoping ("no unqualified drop, no default route in the main
# table") are statements about ALL rules, including the ones that would have to be absent.
# A running cluster can show you which path two pods took; it cannot show you that no third
# rule exists, that no rule is unscoped, or that the vocabulary is closed. The behavioural
# complement — that an UNLABELLED pod really does take the WAN path — is at L2 in
# tests/l2-behavioral/egress-default-path (same requirement label).
#
# ENVIRONMENT-AGNOSTIC: no address is written down. The private ranges the vpn rule must
# exclude are checked as CONTAINMENT of the addresses each environment's own Flux overlay
# declares (pod CIDR, Gateway VIP, LB pool, API host) — so a new environment on a different
# LAN is checked against its own addresses, and the check keeps working when they change.
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this check as claiming them):
# - Behaviour. That a vpn-class pod's packets really leave via tun0, that an unlabelled
# pod's really do not, and that the tunnel is up at all. L2 covers the two labelled
# classes (tests/l2-behavioral/egress-class, R-NET-05) and the unlabelled default
# (tests/l2-behavioral/egress-default-path, R-NET-04); the kill-switch firing is L3.
# - THE RUNNING NODE's routing tables and nftables ruleset. This reads the templates that
# generate them, driven by no node. A hand-added `ip rule` on the gateway node is
# invisible here (and to every other test); drift on the box is an Ansible check-mode
# exercise for the operator.
# - PHYSICAL MULTI-WAN. Out of scope per OQ-1, so its absence is not asserted: there is no
# honest repository signal that would distinguish "one WAN, correctly" from "one WAN,
# because nobody tried" — and inventing one would be a hollow assertion.
# - IPv6. The policy's CIDRs and the routing rules are IPv4-only, matching the platform.
# If IPv6 egress is ever enabled, the `internet` path would need the same analysis and
# this check would NOT catch its absence.

# L0 STATIC — the HA control plane is authored, for every environment (R-PLAT-01) [EXECUTABLE]
# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
# Spec: docs/00 R-PLAT-01 ("The platform MUST run on k3s across 3 nodes with
# production-grade HA control plane in prod; dev/test MAY run fewer nodes but MUST
# exercise the same multi-node topology"), elaborated by docs/01 ("k3s (HA,
# embedded etcd)") and docs/02 ("HA embedded etcd (k3s server on all 3)",
# "3 physical nodes", "no external datastore", "the *same* Ansible bootstrap runs").
#
# WHY L0: R-PLAT-01 has an authored half and an observed half. The authored half — that the
# configuration in git BUILDS a 3-server embedded-etcd control plane in BOTH environments
# from one code path, with exactly one --cluster-init founder, no external datastore, and a
# floating API endpoint that is SAN'd into the serving cert and cannot collide with the
# Service-LB allocator — is provable with no cluster and is ONLY provable here: a live
# cluster cannot tell you what the NEXT environment brought up from this repo would look
# like. The observed half is asserted separately at L2 by
# tests/l2-behavioral/ha-control-plane, which carries the same requirement label.
#
# ENVIRONMENT-AGNOSTIC: no hostname, address, node count or group name is written down.
# Environments are enumerated from the R-ENV-02 seam itself (k3s_primary_group /
# k3s_servers_group in group_vars), and WHICH one is prod is derived from the Flux overlay
# that environment bootstraps (flux_bootstrap_env_path) — never from a group's name.
#
# GIVEN the repository as git tracks it,
# WHEN the inventory, the k3s_server and kube_vip roles, their plays and each
# environment's Flux overlay are parsed and cross-checked against each other,
# THEN k3s is the pinned distro and nothing is installed as an agent; every environment
# resolves to an ODD, quorum-capable server count (prod exactly three) with EXACTLY
# ONE --cluster-init founder and every other server joining it with --server;
# the datastore is k3s's embedded etcd (no --datastore-endpoint, no --disable-etcd);
# the API's floating endpoint is a leader-elected, control-plane-ONLY kube-vip
# DaemonSet on every server whose address is the environment-scoped VIP, that VIP is
# in the apiserver serving cert's SANs together with every server's own address, and
# it is neither a node address nor the ingress Gateway VIP nor inside that
# environment's Cilium LoadBalancer pool; and dev/test and prod are built by the SAME
# roles and plays retargeted by variables only.
#
# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git tree + PyYAML; no
# cluster, no network); conformance/run.sh --layer l0 and ci/l0.sh run it directly, and this
# Chainsaw Test wraps the SAME script.
#
# KNOWN, DELIBERATE GAPS (enumerated in check.sh's header; this test claims none of them):
# * The LIVE clusters' shape (three Ready servers, all etcd members, VIP actually floating,
# API answering through it) — asserted at L2 by tests/l2-behavioral/ha-control-plane.
# * FAILOVER. That the control plane survives losing a server (quorum holds, the VIP moves)
# is a fault-injection claim and is proven NOWHERE yet — tests/l3-fault-injection/node-loss
# drains a node for R-STATE-02's data claim and asserts nothing about the control plane.
# * "Production-grade" as a hardware/performance judgement (operator decision, §2 of
# infra/PROD-PROVISIONING.md).
#
# TWO GAPS CLOSED 2026-09-06 (they used to be listed above; recorded so the change is legible):
# * `K3S_API_HOST` (Cilium's k8sServiceHost) was the PRIMARY NODE's address in both
# environments rather than the floating VIP, contradicting the prod overlay's own comment.
# It was ESCALATED, not asserted, because the workstream could not decide it (R-TEST-06).
# The operator decided the VIP, so it is now ASSERTED — on both sides of the [parity]
# contract and per environment.
# * kube-vip was NOT imported by playbooks/site.yml. It is now, BETWEEN k3s and cilium, and
# the order is asserted — not as a tidiness preference but because the CNI's endpoint is
# the VIP, so an unfloated VIP means a cold build brings up a CNI that cannot reach its
# API server.

# L0 static check (offline, no cluster) — ha-control-plane-as-code
# Serves: R-PLAT-01 ("The platform MUST run on k3s across 3 nodes with production-grade
# HA control plane in prod; dev/test MAY run fewer nodes but MUST exercise the
# same multi-node topology." — spec docs/00-vision-and-scope.md).
#
# The elaborating spec text this check quotes and asserts against:
# docs/01-architecture-overview.md "Kubernetes distro | **k3s** (HA, embedded etcd)"
# docs/02-environments-and-provisioning.md, table:
# "Control plane | HA embedded etcd (k3s server on all 3) | HA embedded etcd

# docs/02 §"k3s topology decisions":
# "HA control plane with **embedded etcd** across all 3 nodes (no external datastore)."

# nodes we do not isolate control-plane nodes."
# "For prod bare-metal, the *same* Ansible bootstrap runs; only the machine-creation
# step differs"
#
# WHY L0 IS THE RIGHT LAYER FOR THESE CLAUSES (and where the rest lives)
# ---------------------------------------------------------------------
# R-PLAT-01 splits cleanly in two, and the halves are provable at different layers:
#
# AUTHORED half — "the configuration in git builds a 3-server HA embedded-etcd control
# plane in BOTH environments, from ONE code path": provable with no cluster, and
# ONLY provable here. A live cluster cannot tell you whether the *next* environment
# brought up from this repo will also be HA, whether a second `--cluster-init`
# founder could exist, or whether an external datastore is configured anywhere. That
# is this check.
# OBSERVED half — "the cluster this suite is pointed at really is 3 Ready servers, all
# etcd members, with the API answering through the floating VIP": that is cluster
# state and lives in tests/l2-behavioral/ha-control-plane (same requirement label).
#
# Neither half is sufficient alone, and this file claims only the first.
#
# ENVIRONMENTS ARE DERIVED, NOT LISTED. The check does not know the words "dev" or "prod"
# as inventory names. It enumerates environments from the R-ENV-02 seam itself — the
# `k3s_primary_group` / `k3s_servers_group` pair in group_vars/all.yml plus every
# group_vars/<group>/vars.yml that overrides them — and identifies WHICH environment is
# prod by the Flux overlay that environment bootstraps (`flux_bootstrap_env_path`), not by
# its group name. Add a fourth prod node, rename a group, or add a third environment and
# the assertions follow; nothing here restates an address, a hostname or a node count.
#
# GIVEN the repository as git tracks it,
# WHEN the Ansible inventory, the k3s/kube-vip roles and plays, and each environment's
# Flux overlay are parsed and cross-checked against each other,
# THEN DISTRO: k3s is the distro, pinned, installed by the one role, and no node is
# installed as an `agent` (an agent is not a control-plane member);
# SERVERS: every environment's server group resolves to a quorum-capable, ODD
# number of hosts (>= 3, tolerating >= 1 loss), the PROD environment to
# EXACTLY three, and each has EXACTLY ONE `--cluster-init` founder while
# every other server joins it with `--server` (so a second founder — the
# split-brain shape — cannot be authored);
# ETCD: the datastore is k3s's EMBEDDED etcd: no `--datastore-endpoint` and no
# `--disable-etcd` anywhere in the provisioning code, so every server is
# an etcd member (docs/02's "no external datastore", "on all 3");
# ENDPOINT: the API has a floating endpoint that survives losing the founder — the
# kube-vip VIP is control-plane-only (never Service LB, or it would fight
# Cilium LB-IPAM for ARP), leader-elected, deployed to EVERY server, and
# baked into the apiserver serving cert's SAN list ALONG WITH every
# server's own address (so TLS validates whichever node answers);
# ADDRESSES: each environment's control-plane VIP is not one of its node addresses,
# is not that environment's ingress Gateway VIP, and lies OUTSIDE that
# environment's Cilium LoadBalancer pool — the two allocators can never be
# handed the same address;
# CNI PATH: the CNI dials the FLOATING endpoint, not a machine (added 2026-09-06). The
# two API addresses stay SPLIT — k3s_api_host is the founder and feeds only
# the cold `--server` join, k3s_apiserver_endpoint derives from
# kube_vip_address and feeds Cilium's k8sServiceHost — the Flux overlay's
# K3S_API_HOST equals that environment's VIP and is none of its node
# addresses ([parity], both halves), the HelmRelease keeps a per-environment
# token rather than a literal, and site.yml floats the VIP BETWEEN k3s and
# Cilium with roles/kube_vip blocking until it answers;
# ONE PATH: dev/test and prod are brought up by the SAME role and the SAME plays,
# retargeted by variables only (docs/02 "the *same* Ansible bootstrap
# runs"), so "exercise the same multi-node topology" is a property of the
# code rather than a coincidence of two hand-written inventories.
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this check as claiming them):
# - THE LIVE CLUSTERS. That three nodes are Ready, that all three are etcd members with
# a healthy quorum, that kube-vip is actually floating the VIP, and that the API
# answers through it. All of that is asserted at L2 by
# tests/l2-behavioral/ha-control-plane, which reads it from the cluster under test.
# - FAILOVER. That the control plane SURVIVES the loss of a server (etcd quorum holds,
# the VIP moves, the API stays up) is a fault-injection claim. The nearest existing
# coverage is tests/l3-fault-injection/node-loss, which drains a node for R-STATE-02's
# data-availability claim and does NOT assert control-plane survival. A dedicated
# "kill the VIP leader / kill the founder" L3 test is the remaining R-PLAT-01 gap and
# is NOT claimed here or at L2.
# - "PRODUCTION-GRADE" AS A HARDWARE/OPERATIONS JUDGEMENT. Whether three converged
# mini-PCs with etcd sharing a spindle with Longhorn is production-grade is an operator
# decision recorded in infra/PROD-PROVISIONING.md §2, not a repository property. This
# check asserts the control-plane TOPOLOGY the spec fixes, not a performance verdict.
# - IPv6 / dual-stack, and any claim about the edge network.
#
# TWO FORMER GAPS ARE NOW ASSERTED, and the reasoning is worth keeping (2026-09-06):
# * CILIUM'S OWN API ENDPOINT used to be listed here as an ESCALATION — `K3S_API_HOST`
# (clusters/*/kustomization.yaml), which becomes Cilium's `k8sServiceHost`, was each
# environment's PRIMARY NODE address rather than the floating VIP, contradicting the prod
# overlay's own comment. Making the check fail over it would have turned the merge gate
# red on a design question this workstream may not decide (R-TEST-06), so it was reported
# instead. THE OPERATOR DECIDED THE VIP on 2026-09-06, which turns the question into a
# repository invariant, and invariants belong in assertions — see the "THE CNI DIALS THE
# VIP" section. Note what made it assertable: the fix SPLIT one variable in two, so there

# k8sServiceHost was each environment's PRIMARY NODE address, so on a 3-server HA control
# plane the CNI's control-plane path depended on one machine. Measured on live prod
# 2026-09-06: all three cilium-agents carried KUBERNETES_SERVICE_HOST=192.168.2.10
# (k3s-prod-1's own address) while kube-vip held 192.168.2.9. That failure is SILENT — the
# datapath keeps serving from Cilium's cache, so nothing looks broken while no service or
# policy update lands at all.
#
# The operator decided the VIP (2026-09-06), so this is now a repository property and belongs
# here rather than in the gap list. THIS IS THE RIGHT LAYER because the claim is about what
# the configuration in git WOULD build, in BOTH environments, including the next one — a live
# cluster can only tell you about itself.
#
# WHAT MAKES THIS CHECKABLE AT ALL is that the fix split one variable into two. Asserting
# "Cilium uses the HA address" requires an HA address to name; before the split there was
# only k3s_api_host, which had to be the founder for the cold join. So the assertions below

# L0 STATIC — a placeholder value in cluster-vars is REFUSED by the guard that owns it
# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
#
# THE BUG CLASS THIS CLOSES (it has now bitten three times in one file). A guard in
# `bootstrap/standup.sh` keys on the SHAPE of a value that lives in
# `clusters/base/cluster-vars.yaml`, and nothing tied the two together. On 2026-09-05 the
# S3 placeholder changed from `TBD-PROD-S3-BACKUP-ENDPOINT` to
# `https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com`; the three guards matched the glob
# `TBD-*`, a PREFIX match, and `fnmatch('https://TBD-R2-…','TBD-*')` is False. All three
# guards silently stopped matching, and `standup.sh resume` would have resumed `velero` on
# prod against a nonexistent hostname: installs clean, reports healthy, NO BACKUPS EXIST.
# It was found by accident. The guard is fixed (`s3_is_placeholder`, substring); the
# COUPLING was untested, which is what makes the class reintroducible.
#
# GIVEN the repository as authored,
# WHEN the REAL predicate is extracted from bootstrap/standup.sh and executed by bash
# (never reimplemented — see check.sh "HOW THE REAL GUARD IS EXERCISED"),
# THEN (1) every authored value of a guarded knob that is placeholder-shaped by an
# INDEPENDENT detector is actually refused by that guard, in base and in every
# environment overlay;
# (2) no environment overlay carries a placeholder-shaped value for a knob no guard
# refuses;
# (3) every function in standup.sh that reads a guarded knob applies the guard to it
# (the "three guards died at once" regression);
# (4) the guard matches its own vocabulary ANYWHERE in a value, not just as a prefix
# — the exact anchoring defect above — and still accepts a real endpoint;
# AND (5) the extraction is faithful, and the check fails LOUDLY rather than silently
# testing a copy if the guard stops being a self-contained predicate.
#
# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (standard library +
# PyYAML + bash); conformance/run.sh --layer l0 runs it directly and this Chainsaw Test

#
# NOT proven: that the endpoint is REACHABLE or that backups exist (runtime facts —
# `standup.sh s3check` probes the former from a pod, l3-fault-injection/dr-restore proves
# the latter); that guards for knobs OTHER than the placeholder-refusing ones are correct;
# and that the guard runs at all in a real standup (the dispatch path is shell, executed
# only against a live cluster). R-STATE-03 is tagged for the narrow static slice only: the

# Serves: R-ENV-02 ("Same GitOps config promotes dev/test -> prod (authored once)."

#
# WHY THIS EXISTS — A GUARD KEYED ON A VALUE THAT LIVES IN ANOTHER FILE
# --------------------------------------------------------------------
# `bootstrap/standup.sh` refuses to resume tiers whose configuration is still a
# placeholder. Three of those guards keyed on the SHAPE of `S3_BACKUP_ENDPOINT`, which is
# authored in `clusters/base/cluster-vars.yaml`. On 2026-09-05 the placeholder changed
# from `TBD-PROD-S3-BACKUP-ENDPOINT` to `https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com`
# (the MinIO -> Cloudflare R2 move). The guards matched the glob `TBD-*` — a PREFIX match —
# and `fnmatch('https://TBD-R2-…','TBD-*')` is FALSE. All three guards silently stopped
# matching. `standup.sh resume` would then have resumed `velero` on prod against a hostname
# that does not exist: the HelmRelease installs clean, the Kustomization reports Ready, and
# NO BACKUPS EXIST. The only reason it was not shipped is that someone noticed by accident.
#
# The predicate is fixed (`s3_is_placeholder`, substring match). The COUPLING is what was
# never tested: a guard in one file keying on a value in another, with nothing tying them
# together. This check is that tie, and it is derived from BOTH real files — no current
# string is hardcoded here, so it does not rot when the placeholder or the guard changes.
#
# HOW THE REAL GUARD IS EXERCISED (and why not a copy)
# ---------------------------------------------------
# `bootstrap/standup.sh` is NOT sourceable: at top level it parses argv, hard-exits when
# --kubeconfig/--expect-server/<step> are absent, `cd`s to the repo root, exports
# KUBECONFIG, installs an EXIT trap and finally dispatches steps against a live cluster.
# So this check EXTRACTS the predicate's own source lines from the file and sources ONLY
# those, then calls the real function. That is the real bytes, not a reimplementation:
# * every function whose name ends `_is_placeholder` is discovered, not named here;
# * a duplicate definition of one is a failure (which of the two would run?);
# * the extracted body must be a SELF-CONTAINED predicate — `case`/`return` and nothing
# else, no command substitution, no call to another function. If the guard ever grows
# a dependency, extraction stops being faithful and THIS CHECK FAILS LOUDLY, naming the
# remedy (move the predicate into a small sourceable library that standup.sh sources)
# rather than quietly falling back to testing a copy of the logic;
# * a CANARY pins the extraction itself: the extracted function must refuse the empty
# string and accept a realistic endpoint. An extraction that grabbed the wrong lines,
# or a predicate degraded to always-true / always-false, fails there — this repo has
# already been bitten by a check that passed when perturbed because it asked a question
# that was always satisfiable.
# There is deliberately NO second implementation of the matching logic anywhere in this file.
#
# THE INDEPENDENT DETECTOR (the other half of the comparison)
# ----------------------------------------------------------
# Asking "does the guard agree with the guard?" proves nothing, so the set of
# placeholder-shaped values is decided by a detector written HERE, whose vocabulary is the
# UNION of two independent sources:
# * SEED — universal loud-placeholder idioms (TBD, TODO, FIXME, PLACEHOLDER, REPLACE-ME,
# CHANGE-ME, FILL-ME, SET-ME, XXXX), plus `<angle-bracket>` templates and the empty
# string. These are NOT derived from the guard, so DELETING a guard arm cannot make a
# value stop being placeholder-shaped — it makes assertion (1) fail, which is the point.
# A value using an idiom the guard does not know is a finding either way: fix it by
# giving the knob a real value, or by teaching the guard the idiom.
# * the guard's OWN vocabulary, read out of its case-arms with the glob anchors STRIPPED.
# Stripping the anchors is what makes the comparison non-circular in the dimension that
# actually broke: the detector matches a word ANYWHERE, case-insensitively, and the
# guard must agree. A prefix-anchored guard cannot pass.
#
# GIVEN the repository as authored,
# WHEN the real predicate(s) are extracted from bootstrap/standup.sh and executed,
# THEN (1) VALUES: for every knob a guard is responsible for, every authored value — the
# base default AND each environment overlay's value — that the independent
# detector calls placeholder-shaped is REFUSED by the real guard, and every value
# it calls usable is ACCEPTED (a guard that refuses a real endpoint leaves velero
# suspended forever, which is the same class of silent failure);
# (2) OVERLAYS: no environment overlay's EFFECTIVE cluster-vars carries a
# placeholder-shaped value for a knob that no guard refuses. (Base alone is
# exempt: it is not a bootstrap target — `flux bootstrap --path=clusters/<env>` —
# and its loud sentinels exist precisely to be overridden. A base placeholder an
# overlay forgets to override IS caught, because it becomes that overlay's
# effective value.)
# (3) CONSUMERS: every function in standup.sh that reads a guarded knob (via `cvar`,
# following one hop of variable aliasing) applies a placeholder guard to it. This
# is the "all three guards died at once" regression stated as a property: the
# guard being correct is worthless if a consumer stops calling it.
# (4) ANCHORING: for each word in the guard's own vocabulary, the guard refuses a
# value carrying that word in the MIDDLE (not at the start) — the precise defect
# of 2026-09-05 — while still accepting a realistic endpoint.
# (5) HARNESS: exactly one definition per predicate, the extracted body is verbatim
# from the file and self-contained, the canary holds, no divergent second copy of
# the matching logic exists elsewhere in standup.sh, and a floor on the number of
# assertions run keeps a pass from degenerating into a no-op.
# AND (6) LOAD-BEARING: ci/l0.sh runs the L0 conformance layer on every gate run and
# ci/gate.sh sets the merge block when that stage fails.
#
# WHAT THIS DOES *NOT* PROVE (honest gaps)
# - Nothing about RUNTIME: not that the endpoint resolves, not that credentials work, not
# that a backup exists. `standup.sh s3check` probes reachability from a pod (operator-
# run, cluster-gated) and conformance/tests/l3-fault-injection/dr-restore proves restore.
# - It does not execute standup.sh's dispatch path, so it cannot prove the guard is
# REACHED in a real run — only that, when reached, it refuses what it must. The
# consumer property (3) is a static approximation of reachability: it is a text-level
# taint trace over one file, not an interpreter, and a guard whose result is computed
# and then ignored would satisfy it.
# - It says nothing about guards keyed on shapes OTHER than placeholders (e.g. the
# EXTERNALDNS_TXT_OWNER_ID == 'default' test), nor about placeholder-shaped values
# outside cluster-vars (the Ansible inventory's BLOCKED/NOT-A-DEVICE sentinels are
# asserted by the node_baseline role itself, at play time).
# - Stage 3b of ci/l0.sh scopes the conformance run to the TOUCHED requirements. An edit
# to bootstrap/* attributes NO requirement in ci/touched-requirements.sh's path map, so
# the touched set is empty and the FULL L0 layer runs (verified: ci/lib.sh
# load_touched_requirements) — this check runs. An edit to clusters/* maps to
# R-ENV-02, which this check carries, so a cluster-vars value change also selects it.
# A change that touches standup.sh ALONGSIDE some unrelated mapped path (say
# platform/cilium/) would scope the run away from this check; closing that needs a
# `bootstrap/*` entry in the path map, which is not this check's file to edit.

# HOW A "MUST NOT" IS MADE TESTABLE — the same discipline as R-TEST-06's test: a

#
# ENVIRONMENT-AGNOSTIC: the prod inventory group is DERIVED (it is the group whose

inspected, then prod is authored as three bare-metal nodes with node-local storage,
bootstrapped by dev's own code retargeted by variables, receiving only

against prod — and it exists only because the roadmap phase was opened.

# Serves: R-ENV-03 ("prod is a 3× mini-PC bare-metal k3s cluster with local storage; it
# MUST NOT be an active development surface until the roadmap declares it ready."
# — spec docs/00-vision-and-scope.md. Detail in docs/02: prod substrate "3× mini-PC

# "For prod bare-metal, the *same* Ansible bootstrap runs; only the machine-creation

# a sandbox (R-ENV-03)". The roadmap gate is roadmap/phases.md Phase 7: entry
# "operator declares prod hardware ready"; note "Do not begin building on prod
# hardware before this phase is explicitly opened".)
#
# HOW A "MUST NOT" IS MADE TESTABLE
# --------------------------------
# The second clause is a governance rule, and the same discipline applies as to R-TEST-06
# (tests/l0-static/spec-immutability-enforced): "nobody developed against prod today"
# cannot be observed, but the PROPERTY THAT MAKES DEVELOPING AGAINST PROD IMPOSSIBLE can
# be. In this repo that property is structural — prod receives the base configuration plus
# environment-scoped overrides and NOTHING ELSE, so there is no place to put prod-only work
# even if someone wanted to. This check asserts that, together with the first clause's
# authored facts (three nodes, no VM IaC behind them, node-local storage, the same
# bootstrap code as dev).
#
# The first clause's HARDWARE facts (that the three machines really are mini-PCs, really
# are bare metal, really hold local NVMe) are operator-attested, not machine-checkable —
# see the gap list. What IS checkable is that the repository describes prod that way and
# that no IaC creates prod nodes as virtual machines.
#
# GIVEN the repository as git tracks it (plus the read-only spec repo when mounted),
# WHEN the prod inventory, the prod overlay, the IaC module and the roadmap record are
# inspected — and, where offline execution is possible, the provisioning chain is
# actually retargeted at prod with `--list-hosts`,
# THEN (1) prod resolves to EXACTLY THREE nodes, reached directly on their own sshd
# (no NAT indirection, i.e. real machines on the LAN);
# (2) NO IaC resource creates any prod node: the VM module's generated node names are
# disjoint from the prod host set and no prod hostname appears anywhere under
# infra/tofu — prod is imaged by the operator (docs/02 stage 1), not instantiated;
# (3) prod's storage is NODE-LOCAL: the Longhorn data path for prod is an absolute
# local path, and the replica count equals the node count (one replica per node's
# own disk). A distinct bulk/media tier is explicitly permitted (R-STATE-04) and
# is not counted against this;
# (4) prod runs THE SAME bootstrap code as dev: the same playbooks/roles, retargeted
# by variables only — every prod group_vars key is an existing role/global
# variable (an invented prod-only knob would be a fork), and no prod-only role
# or playbook exists;
# (5) prod is NOT a development surface: clusters/prod carries only the base plus
# sync.yaml, every patch it applies targets an ENVIRONMENT-SCOPED object
# (cluster-vars, a Flux Kustomization's sops decryption, or the Git source),
# prod's Git ref is the SAME ref dev tracks (no prod-only branch to develop on),
# and no prod-only manifest exists anywhere in the rendered configuration;
# (6) prod artifacts exist only WITH a declaration of readiness: the spec roadmap
# carries the phase that opens prod build (checked when the spec repo is mounted),
# and the repository records that the operator opened it.
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
# - The HARDWARE. That the three nodes are mini-PCs, are bare metal, and present local
# SSD/NVMe is operator-attested in infra/PROD-STANDUP.md / PROD-PROVISIONING.md; the
# node-health and BIOS surveys that establish it write to gitignored artifacts, so
# nothing tracked can be asserted against. Cluster-side, the Kubernetes API exposes no
# "am I virtual" fact either — a bare-metal check would need a privileged host-path
# probe of DMI data, which is a heavier and more invasive test than the claim warrants.
# - The LIVE prod cluster's shape (three Ready nodes, all control-plane+etcd, Longhorn
# disks at the local path). That is cluster state and belongs to R-PLAT-01's
# (currently uncovered) HA test; asserting it here would also make this test
# environment-specific, since the same suite must pass against dev.
# - That prod's HISTORY contains no development. This is the working tree at HEAD.
# - Whether the roadmap SHOULD have opened prod (the entry-gate judgement). Only that
# prod work is accompanied by the operator's recorded declaration.

# L0 STATIC — certificate lifecycle needs no manual step (R-TLS-02) [EXECUTABLE]
# Catalog: docs/14 L0 row ("Pre-apply, in CI") — runs WITHOUT a cluster.
# Spec: docs/00 R-TLS-02 ("Certificates MUST be automatically issued, renewed, and
# revoked without manual steps"); mechanism in docs/08 + ADR-0006.
#
# R-TLS-02 is one adverbial clause plus three runtime verbs. This test asserts the
# clause — "without manual steps" — which in a GitOps platform is a property of the
# REPOSITORY: a human step in the certificate path leaves evidence in git (committed
# cert material, a Gateway serving a Secret nothing declares, an issuer with no
# automated solver, a credential never delivered, auto-approval switched off, or CRs
# nothing reconciles). The three verbs are observed by the companion L2 test.
#
# ENVIRONMENT-AGNOSTIC (R-ENV-02): the issuer a Certificate names is `${ACME_CLUSTER_ISSUER}`,
# so the check resolves it against the BASE cluster-vars default AND every overlay's value and
# requires each resolved issuer to exist. dev's issuer and prod's issuer are both verified from
# one authored assertion, with no hostname, address or environment name written down.
#
# GIVEN the repository as git tracks it,
# WHEN every serving-TLS reference, Certificate, Issuer and the cert-manager release
# is inspected offline,
# THEN every Gateway listener that terminates TLS serves a Secret a tracked Certificate
# produces; no certificate material is committed anywhere; every Certificate's
# issuer resolves — in EVERY environment — to a tracked ACME issuer with an
# automated dns01/http01 solver whose credential is SOPS-delivered from git;
# cert-manager's automatic request approval is not disabled; and every one of
# those objects is rendered by a Flux Kustomization, so nothing in the chain
# depends on a human running kubectl.
#
# STATUS: EXECUTABLE. `check.sh` is a pure offline assertion script (git + PyYAML, no
# cluster, no network); conformance/run.sh --layer l0 and ci/l0.sh run it directly, and

# L0 static check (offline, no cluster) — tls-lifecycle-automated
# Serves: R-TLS-02 ("Certificates MUST be automatically **issued, renewed, and revoked**
# without manual steps." — spec docs/00-vision-and-scope.md; mechanism in
# docs/08-tls-and-certificates.md, ADR-0006.)
#
# WHICH CLAUSE THIS LAYER CAN PROVE — AND WHICH IT CANNOT
# ------------------------------------------------------
# R-TLS-02 has one adverbial clause ("without manual steps") and three verbs
# ("issued", "renewed", "revoked"). In a GitOps platform the *without manual steps*
# clause IS a repository property, and it is the half that can be proven with no
# cluster: if a human had to mint, install, or approve a serving certificate, the
# evidence of that human step would be IN THE REPO — a committed `tls.crt`, a Gateway
# pointing at a Secret nothing declares, an issuer that no automated solver can
# satisfy, a per-cert credential handed over out of band, or an admission path that
# waits for a manual CertificateRequest approval. This check asserts that none of
# those exist and that the automated path is completely wired instead.
#
# The three VERBS are runtime events. They are asserted by the companion L2 test
# (conformance/tests/l2-behavioral/cert-lifecycle-automated), which observes an
# issuance, an unattended renewal, and the withdrawal of a removed certificate. This
# check does NOT claim them; see "WHAT THIS DOES *NOT* PROVE" below.
#
# GIVEN the repository as git tracks it,
# WHEN every serving-TLS reference, Certificate, Issuer and the cert-manager release
# are inspected offline,
# THEN (1) at least one cert-manager `Certificate` is authored (vacuity floor: a repo
# with no Certificate cannot pass this check by having nothing to check);
# (2) every Gateway HTTPS listener that TERMINATES TLS references ONLY Secrets
# that a tracked Certificate declares as its `secretName` — so the serving
# credential is produced by the controller, never dropped in by hand;
# (3) NO certificate material is tracked anywhere: no Secret manifest of type
# kubernetes.io/tls, no tls.crt/tls.key/ca.crt key in any committed Secret
# (plain OR SOPS-encrypted), and no PEM certificate body in any tracked
# YAML — i.e. issuance is not, and cannot silently become, a human step;
# (4) every Certificate's `issuerRef` resolves to a TRACKED issuer IN EVERY
# ENVIRONMENT — the `${ACME_CLUSTER_ISSUER}` token is resolved against the
# base cluster-vars default AND every overlay's value, so an environment
# whose issuer does not exist is caught here rather than at prod bring-up;
# (5) every issuer so referenced is an ACME issuer with a NON-EMPTY solver list
# whose every solver is an automated challenge type (dns01 / http01) — the
# same code path serves issuance AND renewal, so a solver a human must
# complete would defeat both;
# (6) each dns01 solver's provider credential is referenced BY NAME and that
# Secret is delivered SOPS-encrypted from git via a kustomization — the
# operator's one-time token hand-off (docs/08 OQ-4), never a per-cert step;
# (7) cert-manager's automatic CertificateRequest approval is NOT disabled
# (`disableAutoApproval`), and any `approveSignerNames` narrowing still
# covers the ClusterIssuers actually used — a request that waits for a
# human approver is the definition of a manual step;
# (8) the whole chain is reconciled from git — cert-manager's HelmRelease, the
# ClusterIssuers and the Certificate are each included in a kustomization
# that a Flux Kustomization renders — so a deleted Certificate is
# re-created and re-issued with no human action;
# (9) no Certificate defeats renewal arithmetically (`renewBefore` >= `duration`
# would mean the renewal instant never arrives).
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
# - ISSUED: that an issuance actually happens. Asserted at L2 (step 2 of
# l2-behavioral/cert-lifecycle-automated) and, for the real ACME/DNS-01 path,
# evidenced by l2-behavioral/trusted-tls serving a publicly-trusted cert.
# - RENEWED: that a renewal actually happens unattended. docs/08's acceptance gate
# is explicit that this must be "observed across a renewal" — L2 step 3 does that
# by fast-forwarding a certificate's renewal window; nothing static can.
# - REVOKED: NOT PROVEN AT ANY LAYER TODAY, and not asserted here. Two distinct
# readings, neither established: (a) ACME revocation — cert-manager does not
# revoke certificates at all, so no repo state could show it; (b) the spec's own
# reading in docs/08 ("removing/rotating a certificate is a declarative change")
# — withdrawal of a REMOVED certificate's serving material requires cert-manager's
# `enableCertificateOwnerRef`, which the tracked HelmRelease does NOT set (chart
# default false). L2 step 4 asserts the withdrawal behaviour and is expected to
# FAIL until that knob is set; escalated to the PM rather than softened (R-TEST-06).
# - That the tracked Certificate is the one the live Gateway is actually serving
# (cluster state), or that the ACME account/DNS credential is still valid.
# - Certificate EXPIRY ALERTING, which docs/08 delegates to R-OBS-04 (see
# l3-fault-injection/alerting).

# [RUNNABLE / NOT YET EXECUTED — see STATUS]
# Catalog: docs/14 "Trusted TLS (R-TLS-01/02)"
# Spec: docs/00 R-TLS-02 — "Certificates MUST be automatically **issued, renewed,
# and revoked** without manual steps."
# docs/08 §"Renewal & revocation (R-TLS-02)" — "cert-manager renews well
# before expiry automatically; no human action." / "Revocation: removing/
# rotating a certificate is a declarative change; cert-manager handles
# issuance of replacements."
# docs/08 acceptance gate — "Certificates renew automatically ahead of expiry
# with no manual step (**observed across a renewal**)."
# Impl: platform/cert-manager/**, platform/gateway/wildcard-certificate.yaml.
# Sibling: tests/l0-static/tls-lifecycle-automated proves the "without manual steps"
# clause statically (in the merge gate). This test observes the three VERBS.
#
# ENVIRONMENT-AGNOSTIC (R-ENV-02): NOTHING about either environment is written down. The
# serving certificate is DISCOVERED — find the Gateway whose listener terminates TLS, follow
# its certificateRefs Secret, and read that Secret's `cert-manager.io/certificate-name`
# annotation to reach the Certificate. No hostname, no namespace list, no issuer name, no
# address: dev proves dev's cert and prod proves prod's from the same authored assertions.
#
# GIVEN cert-manager reconciled by Flux and a Gateway terminating TLS,
# WHEN the serving Certificate's provenance and renewal schedule are read, and a NEW
# Certificate is then requested, left to renew itself, and removed,
# THEN 1. the serving credential was produced by the CONTROLLER, not a human: its
# Secret carries cert-manager's certificate-name annotation, its
# CertificateRequest was submitted by cert-manager's own ServiceAccount and
# was APPROVED automatically, and its issuer is a Ready ACME ClusterIssuer;
# 2. an unattended RENEWAL IS SCHEDULED: status.renewalTime is in the future and
# strictly before status.notAfter, so no human is in the renewal path;
# 3. ISSUED — a newly declared Certificate becomes Ready and its Secret appears
# with certificate material, with no step between declaring and having it;
# 4. RENEWED — that certificate, given a renewal window that opens one minute
# after issuance, REISSUES ITSELF at least twice (status.revision >= 3) and
# the serving bytes actually change, with no human action. This is docs/08's
# "observed across a renewal", fast-forwarded;
# 5. REMOVED/REVOKED — deleting the Certificate withdraws its serving material.
#
# WHY A HERMETIC SELF-SIGNED ISSUER FOR STEPS 3-5, AND WHAT THAT COSTS
# -------------------------------------------------------------------
# Steps 3-5 need a certificate lifecycle that completes in minutes and repeats on every
# run. Driving that through the real ACME issuer would fire a public Let's Encrypt order
# (and a Cloudflare _acme-challenge write) per conformance run, burning issuance rate
# limits for evidence that is not about ACME: cert-manager's renewal scheduler and
# ownership logic are issuer-independent. So steps 3-5 use a `selfSigned` Issuer created
# in this test's OWN namespace, and the ACME/DNS-01 path is proven elsewhere — step 1-2
# read the REAL wildcard certificate the Gateway serves, and l2-behavioral/trusted-tls
# proves a publicly-trusted LE certificate is actually served (R-TLS-01/03).
# STATED PLAINLY: steps 3-5 do NOT prove the ACME order path renews; they prove the
# CONTROLLER's issue/renew/withdraw automation runs unattended in this cluster, while
# steps 1-2 prove the real serving certificate is on exactly that automated path.
#
# STATUS: RUNNABLE, NOT YET EXECUTED. Steps 1-2 are read-only. Steps 3-5 CREATE an
# Issuer/Certificate (and DELETE the Certificate they created) inside chainsaw's
# per-test namespace — the same class of mutation every other L2 test here performs,
# self-cleaning via namespace teardown, touching no platform object. WS-TEST authored
# them against live dev/prod read-only inspection under an explicit instruction not to
# mutate either cluster, so THE MUTATING STEPS HAVE NOT BEEN RUN. Nothing about the
# suite gates on them: ci/conformance.sh only runs L2/L3 when CLUSTER_AVAILABLE=true.
#
# EXPECTED FAILURE, DELIBERATELY NOT SOFTENED (R-TEST-06)
# ------------------------------------------------------
# Step 5 WILL FAIL as the platform is authored today. cert-manager only garbage-collects
# a Certificate's Secret when the controller runs with `enableCertificateOwnerRef: true`;
# platform/cert-manager/helmrelease.yaml does not set it (chart default false), and the
# live wildcard Secret on both clusters has NO ownerReferences (verified read-only,
# 2026-09-05). So a removed Certificate leaves its credential in place, and "revoked
# without manual steps" does not hold. That is a finding about the platform, not a
# defect in this test: the assertion stays as the requirement reads and is escalated to
# the PM. (ACME revocation proper is not implemented by cert-manager at all.)
#
# KNOWN, DELIBERATE GAPS (this test claims none of these):
# * Not proven: that the CA would refuse a revoked certificate — there is no
# revocation request to make, so nothing observable exists to assert.
# * Not proven: renewal of the REAL wildcard cert (its window opens 30 days before a
# 90-day expiry; a conformance run cannot wait, and forcing it would rotate the
# platform's serving credential). Step 2 asserts the schedule; step 4 asserts the
# mechanism that will act on it.
# * Not proven: certificate expiry ALERTING — docs/08 delegates that to R-OBS-04
# (l3-fault-injection/alerting).

# Catalog: docs/14 L2 row ("real runtime behavior, probes against a cluster")
# Spec: docs/00 R-NET-04 ("The platform MUST support **multiple egress paths** selected by
# routing rules ... realized as two paths — the local `internet` path and the
# in-cluster `vpn` path").
# docs/03 §"Egress routing: two paths, one physical WAN": "the `internet` path is
# simply the default route out".
# docs/03 §"VPN egress model": "**Default is the WAN; the VPN is strictly opt-in.**

# **never** the VPN. Only services labeled `egress-class=vpn` are steered to the
# tunnel"; and the tunnel "is **split-tunnel**: ... only what Cilium points at `tun0`
# uses the VPN."
#
# WHAT THIS PROVES THAT tests/l2-behavioral/egress-class DOES NOT
# --------------------------------------------------------------
# That test (R-NET-05/07) compares two LABELLED pods — `internet` vs `vpn` — and shows their
# public IPs differ, then flips a label. Both of its pods declared a class, so it says nothing
# about the case R-NET-04 actually turns on: a pod that NO routing rule selects. This test adds
# that pod, and asserts the two claims that make a rule-selected path set complete:
#
# TOTALITY — an UNLABELLED pod egresses the WAN, i.e. the same public IP as the
# explicitly-`internet` pod. Absence of a matching rule IS a path, and it is
# the local one. If the steering rule ever widened (an empty selector, a
# matchExpression, a second rule), this pod's IP would move to the tunnel and
# this assertion is what would notice.
# COEXISTENCE — the WAN path and the VPN path are live AT THE SAME TIME, observed in one
# pass: three pods, two distinct public IPs. "Multiple egress paths" is a
# simultaneity claim, not a claim that one switch has two positions.
# PER-DESTINATION SELECTION — the vpn-class pod still reaches an in-cluster/RFC1918
# destination over the LOCAL path while its public traffic is tunnelled. The
# tunnel is destination-scoped (excludedCIDRs), not a default route, so ONE pod
# uses BOTH paths at once.
#
# ENVIRONMENT-AGNOSTIC (R-ENV-02): no address, hostname or range appears. Every assertion is a
# RELATION between observed values (equal / not-equal), so it holds against dev and prod alike
# and survives the WAN or the VPN provider rotating addresses.
#
# GIVEN one unlabelled, one `internet`-class and one `vpn`-class pod — the same workload three
# times, differing only in the class they declare (or do not),
# WHEN each asks an external echo for the public IP it egressed from, and the vpn-class pod
# also resolves a name through the in-cluster resolver,
# THEN the unlabelled pod's public IP EQUALS the internet-class pod's (the default route out
# is the WAN, and the VPN is strictly opt-in);
# AND the vpn-class pod's public IP DIFFERS from both (a second, simultaneously-live path);
# AND the vpn-class pod still resolves in-cluster (its private-destination traffic was not
# swallowed by the tunnel), so the same pod is using both paths at once.
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
# - THAT NO OTHER RULE EXISTS. Three pods cannot enumerate a rule set. That exactly one
# steering rule is authored, that it selects only the vpn class, that no `ip rule` is
# unscoped and no nftables DROP unqualified is the L0 half, in
# tests/l0-static/egress-paths-selected-by-rules (same requirement label).
# - WHICH INTERFACE the packets left by. The observation is the public IP an external echo
# reports; it distinguishes the paths without naming them. Asserting "out tun0" would need
# host-level datapath inspection (Hubble/tcpdump on the gateway node), which no test in
# this suite does.
# - THE KILL-SWITCH. Tunnel-down behaviour is R-NET-06's, at L3 (vpn-killswitch): `vpn`
# fails closed. Its mirror — that `internet` is never blackholed — is asserted statically
# by the L0 half, not here.
# - NODE traffic. docs/03 also says "the nodes themselves" egress the WAN by default. That
# is a host-level fact this test cannot see from a pod.
# - EXTERNAL DEPENDENCY, stated plainly: the public-IP echo (api.ipify.org) is off-cluster,
# so a WAN outage or the echo being down fails this test. That is the same dependency
# tests/l2-behavioral/egress-class already carries; the alternative — trusting the
# cluster's own account of which path it used — would not be a behavioural test at all.
#
# CLEANUP: chainsaw deletes the per-test namespace (all three pods with it). Nothing outside
# that namespace is created or changed — no label on a platform object, no policy edit.

Given an unlabelled, an internet-class and a vpn-class pod, when each observes the public
IP it egressed from, then the unlabelled pod's IP equals the internet-class pod's (the
default route out is the WAN, the VPN is opt-in) while the vpn-class pod's differs — two
paths live at once — and the vpn-class pod still reaches in-cluster destinations over the
local path, so one pod uses both paths simultaneously.

# L2 BEHAVIORAL — the cluster under test IS an HA k3s control plane (R-PLAT-01) [RUNNABLE]
# Catalog: docs/14 L2 row ("real runtime behavior, probes against a cluster")
# Spec: docs/00 R-PLAT-01 ("The platform MUST run on k3s across 3 nodes with
# production-grade HA control plane in prod; dev/test MAY run fewer nodes but MUST
# exercise the same multi-node topology.")
# docs/01 "Kubernetes distro | **k3s** (HA, embedded etcd) | R-PLAT-01/02"
# docs/02 table: "Control plane | HA embedded etcd (k3s server on all 3) | HA
# embedded etcd (k3s server on all 3)"
# "Node count | 3 VMs (mirror prod topology) | 3 physical nodes"
# docs/02 §"k3s topology decisions": "HA control plane with **embedded etcd** across
# all 3 nodes (no external datastore)"; "Nodes are both control-plane and workload
# (3-node converged cluster)".
#
# WHY L2 — AND WHAT L0 ALREADY DID
# --------------------------------
# tests/l0-static/ha-control-plane-as-code (same requirement label) proves the AUTHORED
# half offline: the repo builds a 3-server embedded-etcd control plane in both environments,
# one founder, no external datastore, a leader-elected control-plane-only VIP in the serving
# cert's SANs. It cannot prove that any of it is TRUE OF A RUNNING CLUSTER — an inventory
# entry is not a node, and a templated DaemonSet is not a floating VIP. That is this test:
# every assertion below is read from the cluster the suite is pointed at.
#
# ENVIRONMENT-AGNOSTIC (R-ENV-02): no address, hostname, node count or range is written
# here. The expected node count comes from the cluster's OWN declared identity
# (flux-system/cluster-vars CLUSTER_ENV, via a test-level chainsaw binding — the same
# ConfigMap Flux substitutes from); the control-plane VIP is read out of the kube-vip
# DaemonSet the cluster is actually running; the server addresses come from the Node
# objects; and the LoadBalancer pool the VIP must stay outside of is read from cluster-vars
# too. R-PLAT-01 itself distinguishes prod from dev/test ("3 nodes ... in prod; dev/test MAY
# run fewer"), so the assertion is necessarily environment-AWARE — but it takes the
# environment from the cluster, never from a flag or a literal, which is precisely the
# mechanism the tests/README.md convention prescribes.
#
# GIVEN the cluster this suite is pointed at,
# WHEN its Nodes, its kube-vip DaemonSet and its kube-apiserver endpoints are inspected,
# THEN DISTRO: every node's kubelet is a k3s build (`+k3s`) — the distro really is k3s;
# SERVERS: every Ready node is BOTH control-plane AND etcd (the converged 3-node
# topology docs/02 fixes — no agent-only node, no control-plane-only node),
# the count is ODD and quorum-capable (tolerates >= 1 loss), and it is
# EXACTLY three when the cluster declares itself prod;
# ETCD: every one of those nodes is a REGISTERED embedded-etcd member (k3s stamps
# `etcd.k3s.cattle.io/node-name` on a node that joined the etcd cluster), so
# the datastore is embedded and replicated across all of them;
# VIP: kube-vip is Ready on EVERY control-plane node, is control-plane-only
# (svc_enable=false — it must not contend with Cilium LB-IPAM for ARP), and
# the address it floats is neither a node address, nor the ingress Gateway
# VIP, nor inside the Cilium LoadBalancer pool;
# ENDPOINT: the kube-apiserver answers `/readyz` THROUGH THAT VIP over TLS that
# validates against the cluster CA for the VIP itself — i.e. the VIP really
# fronts the API and the serving cert really carries it;
# EVERY SERVER SERVES: the apiserver also answers `/readyz` on EVERY server's own
# address, again with a CA-valid cert for that address. This is the assertion
# that separates a real HA control plane from one server plus two joiners:
# if only the founder ran an apiserver, the other addresses would refuse.
#
# THE PROBE RUNS IN-CLUSTER, DELIBERATELY. An earlier draft dialled the VIP and the node
# addresses from the RUNNER. That works from a host on the node LAN (verified against prod)
# and FAILS against dev, whose nodes sit behind a NAT the runner reaches only via a
# forwarded port — i.e. it would have made the test a property of where it was launched
# from. A Job on the cluster is on the node network in both environments, so the probe is
# the same probe everywhere. The Job is created imperatively (kubectl heredoc) rather than
# as a fixture file because its address list is DISCOVERED from the cluster at run time —
# writing it into a fixture is exactly the per-environment literal R-ENV-02 forbids.
#
# WHAT THIS DOES *NOT* PROVE (honest gaps — do not read this test as claiming them):
# - FAILOVER / SURVIVAL. Nothing here removes a node. That etcd keeps quorum, that the VIP
# migrates, and that the API stays reachable when a server dies is an L3 fault-injection
# claim and is proven NOWHERE in this suite yet (tests/l3-fault-injection/node-loss
# drains a node for R-STATE-02's data-availability claim and asserts nothing about the
# control plane). This is the largest remaining R-PLAT-01 gap.
# - THE NEXT environment. That the repo would build an HA control plane again is the L0
# half (tests/l0-static/ha-control-plane-as-code).
# - "PRODUCTION-GRADE" as a capacity/performance judgement (operator's, docs/02 + §2 of
# infra/PROD-PROVISIONING.md).
# - THAT THE RUNNING cilium-agents ACTUALLY DIAL THIS VIP. As of 2026-09-06 the repository
# authors `K3S_API_HOST` = the control-plane VIP in both environments (asserted at L0 by
# tests/l0-static/ha-control-plane-as-code, on both sides of the [parity] contract), but
# this test does not read the agents' live `KUBERNETES_SERVICE_HOST`. Until the operator
# applies that change the LIVE agents still carry the PRIMARY NODE's address — measured
# 2026-09-06: all three prod agents on 192.168.2.10 while kube-vip held 192.168.2.9. An
# in-cluster assertion on the agents' endpoint belongs here and is NOT yet written; it is
# the obvious follow-up once the change is applied and would catch drift the L0 check
# cannot see (a hand-edited DaemonSet, a Helm value overridden out of band).
# - etcd health beyond membership registration (raft leader, DB size, alarms) — k3s exposes
# it only on the node-local etcd metrics port, which is not reachable through the
# Kubernetes API this test is allowed to use.
#
# CLEANUP: the probe Job lives in chainsaw's per-test namespace and is deleted with it
# (config/chainsaw-config.yaml skipDelete: false). Everything else is read-only: this test
# creates nothing outside its own namespace and mutates no platform object.

## Why R2 at all
The off-cluster target used to be a MinIO on the Proxmox host (`http://192.168.1.9:9000`). Two things
killed it, both recorded on 2026-09-05:
1. **Prod physically cannot reach it.** Prod is on the SOHO network `192.168.2.0/24`, which is
pfSense's **WAN**; the MinIO sits inside pfSense's LAN `192.168.1.0/24`. Measured *from a pod inside
prod* — the workstation's own reachability proves nothing about pod egress and has misled this
project once already — `curl http://192.168.1.9:9000/minio/health/live` timed out after 15 s.
Reaching it would need a WAN→LAN rule that does not exist.
2. **Dev's "off-cluster" backup was not off-cluster.** That MinIO runs on the *same Proxmox host* as
dev's VMs, so it shared a failure domain with the thing it was backing up.
R2 needs no firewall change, is genuinely off-site, and is already trusted with the OpenTofu remote
state (`infra/tofu/REMOTE-STATE.md`) — the same account, the same kind of token. It is explicitly an
interim decision: *"that's where backups will go for the time being until a better on-prem backup
solution is created."*
---
## 1. Cloudflare: buckets, token, account id
All of this is in the Cloudflare dashboard; none of it touches the cluster.
1. **R2 → Create bucket** → `velero`. Location hint: whatever is nearest; jurisdiction default.
2. **R2 → Create bucket** → `cnpg`.
Both names are fixed by the manifests: `bucket: velero` in `platform/velero/helmrelease.yaml`, and
`cnpg` via `CNPG_BACKUP_PATH` (`s3://cnpg/dev`, `s3://cnpg/prod`). Use exactly those names or change
the manifests — do not improvise.
3. **R2 → Manage API Tokens → Create API Token**
- Permission: **Object Read & Write** (not "Admin Read & Write" — the cluster never needs to create
or delete buckets, and a token that can is a token that can delete your backups).
- **Specify bucket(s):** `velero` **and** `cnpg`. One token scoped to both — the manifests already
assume one shared key, and `s3check` proves both buckets with it.
- Copy the **Access Key ID** and **Secret Access Key**. They are shown **once**. Put them in the
password manager before you do anything else.
4. **Account id** — 32 hex characters, visible in the dashboard URL and in the R2 S3 endpoint the
token page shows you.
**This repo already knows it.** `infra/tofu/backend.r2.hcl` commits
`https://7ce452a1b3d6c86daf2c020edcb82d37.r2.cloudflarestorage.com` for the OpenTofu state bucket,
with the (correct) note that an account id is not a credential. **If the backup buckets live in the
same Cloudflare account as the tofu state — they should; there is no reason for a second account —
then the endpoint is already known and you do not need to look anything up:**
```
https://7ce452a1b3d6c86daf2c020edcb82d37.r2.cloudflarestorage.com
```
Confirm it matches the endpoint on the token page. If it does not, you have two accounts and the
`velero`/`cnpg` buckets are in the other one — use that one's id, and say so in the DECISIONS-LOG.
The endpoint form is always `https://<account-id>.r2.cloudflarestorage.com` — **no bucket in the
hostname** (path-style; see [§6](#6-r2-specific-gotchas)).
---
## 2. Repo values to set
Only **one** non-secret value is missing, and it is not in a secret file:
| File | Key | From | To |
|---|---|---|---|
| `clusters/base/cluster-vars.yaml` | `S3_BACKUP_ENDPOINT` | `https://TBD-R2-ACCOUNT-ID.r2.cloudflarestorage.com` | `https://<account-id>.r2.cloudflarestorage.com` |
Already authored, **do not change**: `S3_BACKUP_REGION: "auto"`, `VELERO_BACKUP_PREFIX` (dev `dev` /
prod `prod`), `CNPG_BACKUP_PATH` (`s3://cnpg/dev` / `s3://cnpg/prod`), and `checksumAlgorithm: ""` on
the Velero BackupStorageLocation.
The placeholder is deliberately loud, and the guards match it as a **substring** — `bootstrap/standup.sh`
refuses to probe it and refuses to resume `velero` while it is there.
---
## 3. Credentials: four Secrets, one command
The R2 key is read by **four** committed SOPS Secrets, in **two** different shapes. No manifest changes
are needed — only the encrypted values change:
| File | Consumer | Shape |
|---|---|---|
| `platform/velero/velero-cloud.sops.yaml` | Velero (`velero-cloud-credentials`, ns `velero`) | `stringData.cloud` — an **AWS INI file**: `[default]` + `aws_access_key_id=` / `aws_secret_access_key=` |
| `platform/keycloak/keycloak-db-backup-credentials.sops.yaml` | CNPG `keycloak-db` (ns `keycloak`) | `ACCESS_KEY_ID` / `ACCESS_SECRET_KEY` |
| `apps/wave-0/nextcloud-db-backup-credentials.sops.yaml` | CNPG `nextcloud-db` | `ACCESS_KEY_ID` / `ACCESS_SECRET_KEY` |
| `apps/wave-0/semaphore-db-backup-credentials.sops.yaml` | CNPG `semaphore-db` | `ACCESS_KEY_ID` / `ACCESS_SECRET_KEY` |
A Secret is namespace-scoped and a Pod reads only its own namespace's, which is why there are four
copies of one key rather than one.
### The one command
```bash
./infra/devcontainer/dev.sh run platform/backup/set-r2-credentials.sh
```
It prompts for the two values (never echoed, never in shell history, never written to a file), writes
them into all four Secrets with `sops set` — which encrypts in place, so **no decrypted copy of any
Secret is ever created** — then decrypts each file back and proves all four now hold the same key by
comparing 32-bit fingerprints. It never prints a credential.
There is deliberately **no plaintext template to fill in and encrypt**. The
`cp x.example x.yaml && $EDITOR && sops -e -i` pattern leaves a plaintext Kubernetes Secret sitting in
the working tree, one `git add -A` away from being in git forever; `sops set` removes that window
entirely. If you would rather edit by hand, `sops platform/velero/velero-cloud.sops.yaml` decrypts to
`$EDITOR` and re-encrypts on save — also with no plaintext on disk — but then you must repeat it four
times and keep them identical yourself.
To check the four files agree without changing anything:
```bash
./infra/devcontainer/dev.sh run platform/backup/set-r2-credentials.sh --check
```
### What is NOT changed
`platform/backup/minio-credentials.sops.yaml` keeps the **MinIO** key. That is not an oversight — it
is what you need to read the pre-migration backups ([§8](#8-going-back-to-minio)). Its
`.yaml.example` sibling documents the MinIO shape and stays accurate for the MinIO target.
Review the diff before committing: you should see **only** `ENC[...]` blobs and `lastmodified`/`mac`
change in four files. If a key name or a `metadata.name` moved, stop.

## 4. Prove the target BEFORE merging
```bash
K=infra/ansible/.cache/dev.kubeconfig # or prod.kubeconfig
./infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig $K --expect-server https://192.168.2.50:6443 \
--s3-endpoint https://<account-id>.r2.cloudflarestorage.com s3check
```
`--s3-endpoint` probes a **candidate** endpoint instead of the live `cluster-vars` value, so the target
is proven before it is authored. Run it against **both** clusters — prod's egress is the whole reason
this migration exists, and it is a different network position from dev's.
`s3check` runs a throwaway pod per credential and, for each, proves:
1. the committed credential **loads and authenticates**, in the exact shape its consumer reads it
(Velero's INI file mounted from the `cloud` key; CNPG's discrete `ACCESS_KEY_ID`/`ACCESS_SECRET_KEY`);
2. the bucket **exists and is listable** under this environment's own prefix (`ListObjectsV2`, the
operation Velero's BSL sync and Barman's WAL scan both perform);
3. **PUT → GET → byte-compare (sha256 + length) → DELETE → confirm-gone** of one throwaway object at
`<prefix>/.s3check/<pod>.probe` — a genuine write, not a HEAD. A HEAD passes with a read-only token
and with R2 rejecting every write;
4. whether the **R2 checksum trap** ([§6](#6-r2-specific-gotchas)) is present, probed on purpose by
repeating the PUT with checksums *enabled*, and named explicitly either way.
It **fails closed**: a pod that cannot be created, an empty log, a missing verdict line, a short
assertion count, an OK-line count that disagrees with the claimed count, or any single failed
assertion all exit non-zero. There is no "reachability unknown, carrying on". Each failure names its
own cause and fix — wrong key, unscoped token, missing bucket, no pod egress, checksum rejection.
It writes and deletes exactly one object per bucket and leaves no pod behind. It applies nothing and
does not enable `velero`.
---
## 5. The verification sequence — and it ends in a RESTORE
**A backup that has never been restored is not a backup.** R-STATE-03 is PROVEN against MinIO; that
proof does not transfer to a different object store with a different S3 implementation.
1. **`s3check` on dev, then on prod.** Both must pass. (§4)
2. Merge the endpoint + the four re-encrypted Secrets. Let Flux reconcile.
3. **Resume `velero`** — `bootstrap/standup.sh … resume` does it once the endpoint is no longer a
placeholder, or `flux resume kustomization velero`.
4. `velero backup-location get` → `default` **Available**. *Available only means the BSL could be
read;* it is not a backup.
5. `velero backup create --from-schedule daily` → wait for **Completed**, then
`velero backup logs <name>`. Watch specifically for `PodVolumeBackup` failures: the PVC-data path
is kopia, a **different S3 client** from the one the BSL uses (see §7), so metadata can succeed
while volume data fails.
6. **Restore.** `velero restore create --from-backup <name> --include-namespaces <scratch-ns>` into a
*scratch* namespace, and verify the PVC contents actually arrived — not just that the Restore says
Completed. This is the R-STATE-03 re-proof.
7. **CNPG PITR.** Confirm WAL is arriving:
`kubectl -n keycloak get cluster keycloak-db -o jsonpath='{.status.conditions}'` (look for
`ContinuousArchiving`), and that objects exist under `s3://cnpg/<env>/keycloak-db/`. Then do the
restore that matters: a `Cluster` with `bootstrap.recovery` from the barman object store into a
scratch namespace, and check the recovered database actually contains data. The existing
`conformance/tests/l2-behavioral/keycloak-db-dr` and `l3-fault-injection/dr-restore` tests are the
harness for this; they must be re-run **against R2**, and their previous PROVEN state records MinIO,
not R2.
8. Only after 6 and 7 pass may this migration be described as done, and the ledger updated. Until
then the honest status is "R2 accepts objects; recovery from R2 is untested".
---
## 6. R2-specific gotchas
**`region: auto`.** R2 accepts nothing else, and S3 clients require *some* region. Authored as
`S3_BACKUP_REGION: "auto"`. This repo already learned it — `infra/tofu/backend.tf` carries
`region = "auto" # R2 ignores region, but the S3 backend requires a value.`
**`checksumAlgorithm: ""` — do not delete this line.** `velero-plugin-for-aws`'s own
`backupstoragelocation.md` for **v1.14.2** (the pinned version) documents:
> `checksumAlgorithm` — The checksum algorithm to use for uploading objects to S3. Supported values
> "CRC32", "CRC32C", "SHA1", "SHA256". If the value is set as empty string "", no checksum will be
> calculated and attached to the request headers. **Optional (defaults to "CRC32")**
So *omitting* the key means CRC32 **is** sent: `x-amz-sdk-checksum-algorithm` +
`x-amz-checksum-crc32`. This repo has already measured that R2 rejects AWS checksums — that is exactly
why `infra/tofu/backend.tf` needs `skip_s3_checksum = true # R2 rejects AWS trailing (streaming)
checksums.` for the state bucket. The plugin's own compatibility table lists `checksumAlgorithm=""` as
the remedy for the same failure on Ceph S3, Backblaze B2 and IBM COS. If backups start failing with
**HTTP 400 `InvalidArgument`** after a plugin bump, look here first. `s3check` probes for this on
purpose and names it.
**Path-style.** `s3ForcePathStyle: "true"` is authored and correct for R2 as well as MinIO. Never put
the bucket in the hostname.
**No bucket auto-creation.** Velero does not create buckets and the token deliberately cannot. A
missing bucket is a `NoSuchBucket` at runtime; `s3check` catches it first.
**Token scope is per-bucket.** A token scoped only to `velero` authenticates fine and then 403s on
`cnpg` — the two consumers fail independently and quietly. `s3check` proves both.
**Both clusters share one endpoint.** Isolation is by path only (`VELERO_BACKUP_PREFIX`,
`CNPG_BACKUP_PATH`), because R2 is one environment-independent URL. Those two knobs are load-bearing:
without them prod would adopt and TTL-delete dev's Velero backups, and both clusters' identically-named
CNPG Clusters would interleave their WAL into one Barman stream, destroying PITR for both.
---
## 7. What is proven, and what is not
**Proven (2026-09-05, WS-BACKUP, against the live dev cluster and its MinIO at
`http://192.168.1.9:9000`):**
- the rewritten `s3check` itself: 7 assertions per credential path, both credential shapes, from
in-cluster pods — credential load, bucket list, PUT/GET/byte-compare/DELETE/confirm-gone, no object
and no pod left behind;
- its failure paths: the `TBD` placeholder is refused; an unreachable endpoint (`:9099`) produces a
named no-egress failure and exit 1, not a pass;
- MinIO accepts a checksum-bearing PUT, i.e. the trap is a *non-*MinIO problem, and
`checksumAlgorithm: ""` is harmless there.
**Established from the pinned versions (documentation and image inspection, not measured against R2):**
- `velero-plugin-for-aws` **v1.14.2** pairs with Velero **v1.18.x** (upstream compatibility table) and
defaults `checksumAlgorithm` to `CRC32` — so the authored `""` is load-bearing, not decoration.
- That plugin's "Non-AWS S3 compatible provider known issues with plugin v1.14.x" table **does not
mention Cloudflare R2 at all** — neither as working nor as broken. There is no upstream statement to
lean on in either direction.
- **The PVC-data path is a different S3 client.** `checksumAlgorithm` is a BackupStorageLocation
*object-store plugin* setting. Velero's File System Backup uploads through the unified repository's
kopia S3 backend (`pkg/repository/udmrepo/kopialib/backend/s3.go` in Velero v1.18.0), which
references only endpoint/region-style options and has **no checksum knob at all**. So R2
compatibility for backup *metadata* and for *volume data* are two separate questions, and only step
5 of §5 answers the second.
- **CNPG/barman is likely clear of the checksum trap, by version.** Inspected inside the live
`ghcr.io/cloudnative-pg/postgresql:16.4` image on dev: `barman-cloud-wal-archive 3.11.1`,
`botocore 1.35.60`, `boto3 1.35.60`. That botocore predates the 1.36 line in which botocore began
attaching CRC32 request checksums by default (the change that introduced
`AWS_REQUEST_CHECKSUM_CALCULATION`), so this image should not send them.
**Forward risk:** barman-cloud exposes **no** `checksumAlgorithm` equivalent. If the CNPG image is
ever bumped to one carrying botocore ≥ 1.36, WAL archiving to R2 could start failing with 400
`InvalidArgument` and there is no config knob to turn it off — only `AWS_REQUEST_CHECKSUM_CALCULATION=when_required`
in the Pod environment, which CNPG does not currently set. Treat a CNPG image bump as a change that
must be re-verified against R2.
**Not proven, at all:**
- that Velero can write a usable backup to R2 (metadata or kopia volume data);
- that CNPG/barman can archive WAL to R2 and that a `bootstrap.recovery` from R2 succeeds;
- that a restore from R2 yields correct data. R-STATE-03's PROVEN state is **MinIO-only**.
---
## 8. Going back to MinIO
The MinIO copy is **not deleted** and stays restorable. To read pre-migration backups:
1. `clusters/base/cluster-vars.yaml` → `S3_BACKUP_ENDPOINT: "http://192.168.1.9:9000"`
2. `VELERO_BACKUP_PREFIX` → `""` (the MinIO backups are at the **bucket root**, not under `dev/`) and
`CNPG_BACKUP_PATH` → `s3://cnpg` (Barman objects are at `s3://cnpg/<clusterName>/`).
3. Restore the MinIO credential into the four Secrets. `platform/backup/minio-credentials.sops.yaml`
still holds it: `sops -d --extract '["stringData"]["ACCESS_KEY_ID"]'` it and feed the two values to
`platform/backup/set-r2-credentials.sh` (the script cares about the *shape*, not the provider).
4. `S3_BACKUP_REGION` may stay `auto` — MinIO ignores the region.
5. **Dev only.** Prod cannot reach that MinIO at all (§Why R2); pointing prod back is not an option.
Reverting for a restore and then returning to R2 costs another PITR reset. Prefer restoring from MinIO
into a *scratch* namespace on dev with a second, temporary BackupStorageLocation over flipping the
whole cluster's endpoint back and forth.
---
## 9. Merging this resets dev's PITR window
Say it out loud before merging, because it is not recoverable by retrying:
- Dev's R2 prefix starts **empty**. Velero writes a **fresh kopia repository** — the first backup is a
full upload of every included PVC, and no earlier restore point exists in R2.
- Every CNPG Cluster takes **new base backups** (`ScheduledBackup … immediate: true`), and the 30-day
Barman retention window (`retentionPolicy: "30d"`) rebuilds **from zero**. For roughly a month, dev's
point-in-time recovery reaches back only as far as the merge.
- The MinIO copy still holds the old window (§8), but reaching it means reverting the endpoint — so it
is a deliberate excursion, not a fallback that happens automatically.
**Do not merge this while dev's proven MinIO restore is the only recovery path you are relying on.**
The same applies to prod the day it first backs up anywhere.

past kubectl's 256 KiB `last-applied-configuration` annotation limit, so Helm's client-side apply

Kyverno's Deployments come up with no API types, `platform` never goes Ready, and all 9
downstream Kustomizations stall behind it. Dev only ever had them because the command was once

- **The fix, in git:** `bootstrap/flux/bootstrap.sh` now runs `./preapply-crds.sh` as step
**[2/4]** — after `flux install`, before `kubectl apply -k ${FLUX_ENV_PATH}`. It renders the
chart, keeps only `kind: CustomResourceDefinition` documents, applies them
`--server-side --force-conflicts` (no annotation, so no size limit), then waits for
`condition=Established`. The chart name, version constraint, repo URL and namespace are
**derived from that same HelmRelease/HelmRepository** — there is no second copy of the version
to drift, and a Renovate bump of the one pinned line carries this step with it.
- **No environment fork (R-ENV-02):** the script names no environment and takes no overlay
input; it reads repo files and acts on `$KUBECONFIG`. Dev and prod run the identical step, so
`roles/flux_bootstrap` needed **no change** — it already calls `bootstrap.sh`, the single
entrypoint.
- **It cannot silently skip.** Three guards, and deliberately no opt-out flag: a derived
coordinate that is empty/`null` aborts; a render that yields **0** CRDs aborts (an empty
stream would otherwise `kubectl apply` cleanly and exit 0 — the silent-success failure mode
that has bitten this repo repeatedly); and every applied CRD must reach `Established`.
- **Toolchain:** needs `helm` and `yq` on PATH in addition to `flux`/`kubectl` — both are baked
into `infra/devcontainer` (`HELM_VERSION=3.16.0`, `YQ_VERSION=4.44.6`), and `bootstrap.sh`

## 9a. PROD BRING-UP STATE (2026-09-04) — what came up, and the TWO blockers that need the operator
Prod's `platform` tier was unsuspended after the Kyverno CRDs were pre-applied (see §7). Result:
**8 of 9 HelmReleases Ready, 76/76 pods Running** — cert-manager, CNPG, Cilium, Longhorn,
kube-prometheus-stack, Loki, Alloy, external-dns. `platform` itself is **not** Ready, and the 10
downstream tiers remain blocked behind it. Two distinct problems, both needing an operator decision.
### The CRD pre-apply itself: WORKED, and is now proven against a live API server
22 CRDs applied server-side and all reached `Established`; a second run was a clean no-op (`rc=0`),
so the idempotency claim is proven, not asserted. Reproduced under the **pinned** toolchain
(helm 3.16.0, yq 4.44.6) matching an independent helm 3.20.0 run byte-for-byte: `3.9.x` → 3.9.0,
22 CRDs, 5,636,155 bytes.
**The CRDs were the real cause of a 4½-hour crash loop.** Kyverno's four Deployments had **55
restarts each** and stabilised within minutes of the CRD apply — its controllers were coming up with
no API types to watch. That is the failure mode §7 predicted, observed.
### BLOCKER 1 — Kyverno's Helm release is stuck in `uninstalling`
Diagnosis chain, from the HelmRelease conditions:
```
Released: InstallFailed — Helm install failed ...: context deadline exceeded
Remediated: UninstallFailed — Helm uninstall remediation ... timed out waiting for the condition
Ready: StateError — unable to determine state for release with status 'uninstalling'
```
The install timed out **because** the pods were crash-looping without CRDs. `install.remediation.
retries: 3` then triggered an uninstall, and that uninstall itself timed out — leaving
`sh.helm.release.v1.kyverno.v1` with `status=uninstalling`. helm-controller cannot proceed from that
state, so `platform` (which has `wait: true`) never goes Ready and all 10 tiers below it stay blocked.
**The Deployments are healthy and at the right chart version** (kyverno-3.9.0), so this is purely a
stale Helm bookkeeping record, not a broken workload.
**Remediation requires a destructive command and was deliberately NOT run unattended:**
```
helm uninstall kyverno -n kyverno --no-hooks --wait=false # clear the stuck release
flux reconcile helmrelease kyverno -n kyverno --force # let Flux install cold, CRDs now present
```
This is safe on prod specifically because prod carries no real workloads yet, and a clean cold
install is the stronger outcome: it *proves* the bootstrap path this repo now automates. Note the
`failurePolicy: Fail` webhooks (`kyverno-policy-*`, `kyverno-exception-*`, `kyverno-cleanup-*`,
`kyverno-global-context-*`) gate only **Kyverno's own** resource types, so a brief absence does not
block ordinary workload admission. The pre-applied CRDs live **outside** the Helm release and
survive the uninstall, which is exactly why the pre-apply had to be a separate step.
### BLOCKER 2 — prod's external-dns is an ARMED footgun: the installed release predates the fix
**This is the more dangerous of the two.** Prod's live external-dns Deployment renders:
```
--policy=sync --registry=txt --domain-filter=keithjackson.dev --provider=cloudflare
```
**and NO `--txt-owner-id`.** Absent that flag external-dns falls back to the chart default `default`
— which is precisely the owner under which **all 36 of dev's TXT registry entries are recorded**.
Scaling this Deployment to 1 would make prod claim dev's records and, under `policy: sync`,
**delete them: the 2026-09-04 incident, exactly.**
The repo is CORRECT and is not the problem. `platform/externaldns/helmrelease.yaml` sets
`txtOwnerId: "${EXTERNALDNS_TXT_OWNER_ID}"`, prod's applied `cluster-vars` resolves it to `prod`, and
the **live HelmRelease `spec.values` carries `txtOwnerId: "prod"`**. Verified against the real chart:
`helm template external-dns --version 1.21.1` with `txtOwnerId: prod` renders `--txt-owner-id=prod`,
so the values key is right and an upgrade *would* fix it.
**The fault is Helm/Flux state, not authoring.** `helm get values external-dns` shows the INSTALLED
release carries `policy` and `domainFilters` but **no `txtOwnerId`** — it predates `c8c1d29`. Yet
helm-controller reports `Ready=True`, `observedGeneration=3`, and a history entry whose
`configDigest` **equals** `lastAttemptedConfigDigest`, i.e. **it believes it has already deployed the
current config.** So it will never upgrade on its own, and the stale release persists indefinitely.
**The only thing preventing the incident was `replicas=0` — manual drift from the incident recovery,
which any Helm upgrade would reset to the chart default of 1.** That is not a guard; it is luck.
Containment applied (reversible, and it costs nothing because prod publishes no hostnames yet — the
app tiers are suspended): **`flux suspend helmrelease external-dns -n external-dns`**, with
`replicas` left at 0. Flux can now neither upgrade the release nor reset the replica count.
**Verified remediation, in this order — the ordering is the whole point:**
1. Force the upgrade so the release picks up `txtOwnerId`, but **do not let the pod run before the
flag is confirmed present.** The naive `resume` + `reconcile --force` resets `replicas` to 1 and
starts the pod in the same operation, so there is no window in which to check — a race against a
process whose failure mode is deleting dev's DNS.
2. Confirm the live Deployment args contain **`--txt-owner-id=prod`**.
3. Only then allow it to scale to 1, and immediately diff the Cloudflare zone against a
pre-recorded snapshot.
**Dev was verified unharmed throughout this work:** the Cloudflare zone was snapshotted before
unsuspending `platform` and re-queried after — **57 records, byte-for-byte identical, all 36 TXT
entries still `owner=default`.** Snapshots are taken against the **Cloudflare API**, never a local
resolver (a pfSense override produced a false healthy reading during the incident).

### The architecture decision (operator) — **INVERTED 2026-09-04, this is the current target**
### The architecture decision (operator)
```
dev -> *.dev.home.keithjackson.dev gitea.dev.home.keithjackson.dev
prod -> *.home.keithjackson.dev gitea.home.keithjackson.dev (THE APEX)
dev -> *.dev.home.keithjackson.dev gitea.dev.home.keithjackson.dev
prod -> *.prod.home.keithjackson.dev gitea.prod.home.keithjackson.dev
apex -> CNAME <svc>.home.keithjackson.dev -> <svc>.prod.home.keithjackson.dev
```
**Prod *is* the apex. There is no `prod.` label and no CNAME layer at all** —
`<svc>.home.keithjackson.dev` is prod's real name, not an alias for one. This **supersedes** the
interim split committed earlier the same day (`c8c1d29`), which put prod on
`*.prod.home.keithjackson.dev` behind apex CNAMEs pointing at it. That layer is deleted: fewer
moving parts, no CNAME chain to keep in step, and prod ends up on the names users already type.
### PHASE 1 — **prod only. Dev did not move.** (this change)
The cost of the inversion is that **dev must move**, and dev is the live cluster. The interim split
was chosen precisely because it moved only the unbuilt environment; this one does not have that
property, so the whole of §10's remaining risk now sits on dev's side, and it is sequenced below.
`BASE_DOMAIN` is now real: every hostname in every Flux-reconciled manifest derives from it.
### The values, per environment
| | `BASE_DOMAIN` | `EXTERNALDNS_TXT_OWNER_ID` | `EXTERNALDNS_DOMAIN_FILTER` |
|---|---|---|---|
| base default | `home.keithjackson.dev` | `unset-see-cluster-vars` (non-colliding sentinel) | `keithjackson.dev` |
| **dev** | `home.keithjackson.dev` (**unchanged**) | `default` (**must not change**) | `keithjackson.dev` |
| **prod** | `prod.home.keithjackson.dev` | `prod` | `prod.home.keithjackson.dev` |
| | `BASE_DOMAIN` | `EXTERNALDNS_TXT_OWNER_ID` | `EXTERNALDNS_DOMAIN_FILTER` | Ansible `k3s_base_domain` |
|---|---|---|---|---|
| base default | `dev.home.keithjackson.dev` | `unset-see-cluster-vars` (non-colliding sentinel) | `keithjackson.dev` | `dev.home.keithjackson.dev` (role default) |
| **dev** | `dev.home.keithjackson.dev` | `dev` | `keithjackson.dev` | (inherits the role default) |
| **prod** | `home.keithjackson.dev` | `prod` | `keithjackson.dev` | `home.keithjackson.dev` (`group_vars/k3s_prod`) |
**Dev's effective hostname is deliberately still the apex `home.keithjackson.dev`.** Moving prod
alone ends the collision and unblocks prod, and it is the whole of the risk that had to be taken
while the operator is away. Dev's rendered output is **byte-identical** except for one added line,
`txtOwnerId: default`, which is the value dev's external-dns was already using implicitly — verified
by rendering all 12 `substituteFrom` paths through `kubectl kustomize | flux envsubst --strict` for
both overlays and diffing.
`[parity]`: `k3s_base_domain` must equal the same cluster's `BASE_DOMAIN`. The kube-apiserver's
`oidc-issuer-url` is a k3s **server flag** in `/etc/rancher/k3s/config.yaml`, not a manifest, so Flux
post-build substitution can never reach it — hence one fact in two places. If they disagree the
apiserver validates tokens against a different Keycloak than the cluster runs: kubectl SSO fails
while the cert-based admin kubeconfig keeps working, so it presents as "SSO is broken", not as skew.
**Two independent guards now, either sufficient alone:**
**`EXTERNALDNS_DOMAIN_FILTER` is the Cloudflare ZONE for BOTH, and must stay that way.** FINDING
F-DNS1 (DECISIONS-LOG 2026-08-17): the Cloudflare provider uses this value for **zone selection** as
well as record matching, so a filter that is a strict subdomain of the hosted zone matches **no
zone** — external-dns generates the record and then skips it with *"no hosted zone matching record
DNS Name"*, publishing **nothing**. This has been "hardened" and reverted more than once. It is not
defence in depth; it is a total outage of DNS publication. Isolation comes from the two guards below,
which a domain filter cannot provide anyway: both environments live in the one zone regardless.
1. **`txtOwnerId`** — per-environment identity. A cluster only ever touches records it owns. This is
the direct fix for the incident. Dev **must** render exactly `default`: its live records are
already registered under that owner, and any other value would make dev's own external-dns stop
recognising them and re-create duplicates beside the orphans.
2. **`domainFilters`** — per-environment name scope. Prod cannot see a name outside its own subtree.
Defence in depth, added because the first guard is a single string in a single file.
**The two guards that actually work:**
1. **`txtOwnerId`, per-environment identity** — a cluster only ever reconciles records its own owner
id claims in the TXT registry. This is the direct fix for the incident.
2. **Disjoint hostname sets** — after the migration the two clusters never describe the same record,
so there is nothing to fight over. *This guard does not exist during the migration window*, which
is the entire reason the ordering below is mandatory.
#### Why dev's owner id changed from `default` to `dev`
Until this migration dev **had** to render `default`: its live apex records were already registered
in Cloudflare's TXT registry under that owner, and renaming would have orphaned every one of them.
**The migration dissolves that constraint** — on `*.dev.home.keithjackson.dev` dev publishes an
entirely new record set with no prior registry entries to recognise, so the id is free and is chosen
on its merits. `default` has none: it is the value external-dns uses when you **forget** the flag,
which is exactly how both clusters came to share it, and an environment whose identity is the
forget-value can never be told apart from a misconfigured newcomer. Consequences, both deliberate:
- Dev's **old apex records stay owned by `default`**, which no environment now claims, so nothing
deletes them implicitly on some future reconcile. Retiring them is an explicit step (**D7**) and
prod's first publish is gated on that retirement being *confirmed* — not on two reconcile loops
racing each other.
- **Prod stays `prod` and must never be given `default`.** Prod is taking over the apex *names*, and
dev's existing apex records are registered under `default` — so `default` is the one value that
would let prod adopt them, and under `policy: sync` delete the ones no prod source claims, on a
cluster dev is still serving. That is the 2026-09-04 incident re-armed with the roles swapped.
Prod inherits the apex **names**; it must never inherit the apex **owner id**.
All three values differ, and the base default remains a sentinel so an environment that forgets the
knob owns nothing and can therefore delete nothing.
### PHASE 1 — prod tokenized and moved off dev's names (`c8c1d29`, done; suffix since inverted)
`BASE_DOMAIN` was a **dead knob** — declared in `clusters/base/cluster-vars.yaml` and referenced by
no reconciled manifest, because every hostname was a hardcoded literal. `c8c1d29` made it real (141
references across the reconciled set) and gave prod its own suffix. That work stands; only the
*value* prod holds has changed, from `prod.home.keithjackson.dev` to the apex.
The base default for the owner id is a **non-colliding sentinel, deliberately not `default`**: a
future environment that forgets the knob must not silently inherit dev's identity — that is exactly
what happened here. With the sentinel such a cluster owns nothing, so it can delete nothing.

declares no `postBuild.substituteFrom`, so `gitea.${BASE_DOMAIN}` there would ship the **literal

this). It is a hand-maintained literal that must move in lockstep with `BASE_DOMAIN`.

validates tokens against a different Keycloak than the cluster runs and kubectl SSO fails while the
cert-based admin kubeconfig keeps working (so it looks like "SSO is broken", not like config skew).

### A pre-existing prod problem this incidentally FIXED
## 10a. THE MIGRATION RUNBOOK — ordering is load-bearing
§4 recorded that prod nodes use **public** resolvers, so the kube-apiserver would resolve its OIDC
issuer publicly and get **dev's** Gateway VIP (192.168.1.53) — the wrong cluster on the wrong LAN,
making prod kubectl SSO impossible, and requiring an `/etc/hosts` pin as a workaround. With prod on
its own subdomain the public record for `keycloak.prod.home.keithjackson.dev` is published by
**prod's own** external-dns pointing at **prod's** Gateway VIP (192.168.2.20), so the public answer
and the split-horizon answer agree. **No `/etc/hosts` pin is needed.** This holds only once prod's
external-dns has actually published the record; until then use the break-glass cert kubeconfig.
> **Prod's `platform` tier and its 10 downstream tiers are SUSPENDED and must stay suspended until
> step P1.** Nothing below is safe to run out of order, and nothing below should be run while the
> operator is away.
### Verify on prod's first reconcile
### The two ways this goes wrong
- [ ] **`domainFilters` zone selection.** The Cloudflare provider uses this value for *zone* lookup
as well as record matching, and in 2026-08 a strict-subdomain filter dropped the parent zone
("no hosted zone matching record DNS Name"). If prod's external-dns logs no matching zone it
will create **nothing** — fail-closed, never destructive. Fallback: set prod's
`EXTERNALDNS_DOMAIN_FILTER` back to `keithjackson.dev` and rely on `txtOwnerId`, which is
sufficient on its own.
- [ ] **Prod's wildcard cert is `*.prod.home.keithjackson.dev`** and solves DNS-01 without touching
dev's `_acme-challenge` records.
- [ ] **Dev's records are untouched** after prod's tiers are resumed. Confirm dev's TXT registry
entries still read owner `default` and that prod's read owner `prod`.
- [ ] **Prod's own Keycloak realm + per-service client secrets** exist (every `*.sops.yaml` client
secret is realm-scoped; prod cannot reuse dev's).
**(1) BOTH CLUSTERS ON THE APEX — the 2026-09-04 incident, recreated.** If prod publishes
`*.home.keithjackson.dev` before dev has vacated it, two clusters describe the same records in the
same zone again. Distinct `txtOwnerId`s stop prod from *deleting* dev's records — that guard holds —
but they do not stop the second failure mode: both clusters requesting a `letsencrypt-prod` wildcard
for the **same name set** and racing each other's `_acme-challenge` TXT records, so neither reliably
solves DNS-01. **Rule: dev vacates the apex first, and the vacate is verified against Cloudflare
before prod is unsuspended.**
### PHASE 2 — dev migration + apex CNAMEs (**deferred, not done**)
**(2) THE STRAND — dev's GitOps source is the thing that moves.** `spec.url` of dev's
`GitRepository` is `https://gitea.home.keithjackson.dev/...`, which is **both** dev's GitOps source
**and** the PM's push target. Flipping dev's `BASE_DOMAIN` moves Gitea's HTTPRoute, its public DNS
record and the wildcard cert covering it to `gitea.dev.home.keithjackson.dev` all at once. If that
host does not already resolve and serve a valid, Ready cert at that instant, **dev stops reconciling
and cannot be fixed by pushing** — the broken thing *is* the path Flux uses to read pushes. Recovery
is then hands-on and needs LAN access to the cluster.
Deliberately not attempted here: dev is **live** (18 Longhorn volumes, working SSO) and it hosts the
Gitea that is currently this repo's GitOps source. Moving it is a migration, not a variable change.
Required, roughly in order:
**(2b) AND THE MERGE ITSELF IS THE TRIGGER.** `clusters/dev/sync.yaml` is a self-managing root

remains. **This is the gate on the whole P sequence.** A pfSense/PiHole override is not
evidence about public DNS.
### D0/D1 AS EXECUTED (2026-09-04) — and the self-reference that would have undone it
D1 was taken via the **repoint** option, not the suspend option, because it is strictly stronger:
suspending only defers the strand, while repointing removes the dependency that causes it. Dev's
`GitRepository` now reads **`http://192.168.2.132:3000/Home-Network/home-network-k3s-impl.git`,
branch `dev-live`** — IP-addressed, plain HTTP, so it depends on **neither DNS nor TLS**, which is
exactly the property needed during a DNS/TLS migration. **A merge to `main` is now inert for dev.**
**THE TRAP, and it is not obvious: a bare copy of `main@4809199` on the bootstrap Gitea would NOT
have held.** The root Kustomization renders `./clusters/dev`, and `clusters/dev/kustomization.yaml`
*contains the patch that sets `GitRepository.spec.url`*. So Flux would have fetched from the
bootstrap Gitea, applied the manifests it found there, and those manifests would have set the url
straight back to `gitea.home.keithjackson.dev` — reverting the repoint on the next reconcile and
re-arming the strand. **The branch must declare its own source.** `dev-live` (`a4a3c2e`) therefore
carries exactly one content change on top of `4809199`: `clusters/dev/kustomization.yaml`'s url +
`ref.branch`. Proven by `kubectl kustomize clusters/dev` at both revisions differing in **exactly
two lines** out of 357. The same property makes the revert self-sustaining in reverse, since
`main@4809199` carries the `gitea.home…` url. Revert command: see `REVERT.txt` in the run scratchpad.
Verified after the cutover: **13/13 Kustomizations Ready** on `dev-live@a4a3c2e`, `cluster-vars`
byte-identical to the D0 snapshot (27/27 keys, `BASE_DOMAIN` still `home.keithjackson.dev`),
**18/18 Longhorn volumes attached+healthy**, all 16 HTTPRoute hostnames still on the apex,
`wildcard-home` still Ready, and the Cloudflare record set re-queried and diffed **byte-for-byte
against the D0 snapshot — identical** (57 records, 36 TXT all `owner=default`).

### P — prod takes the apex
- [ ] **P1. Only now unsuspend prod**, in dependency order: `flux resume kustomization platform`,
then the 10 downstream tiers. Confirm D8 first, in Cloudflare, not from a local resolver.
- [ ] **P1. Unsuspend prod**, in dependency order: `flux resume kustomization platform`, then the
10 downstream tiers.
**CORRECTION (2026-09-04) — the D8 gate is on prod taking the APEX, not on prod coming up.**
This step originally read "only now unsuspend prod", which silently assumed prod would be
serving `*.home.keithjackson.dev`. It is not: prod runs revision `c8c1d29`, where
`BASE_DOMAIN=prod.home.keithjackson.dev` and `EXTERNALDNS_TXT_OWNER_ID=prod`. Prod's names are
therefore a **disjoint subtree** under a **distinct registry owner**, so neither incident mode
of §10a applies: it cannot claim dev's `default`-owned records, and its wildcard
`*.prod.home.keithjackson.dev` is a **different name set** from dev's, so it has its own
Let's Encrypt duplicate-certificate bucket and races no `_acme-challenge` with dev.
**Prod may therefore be brought up in full while dev still holds the apex** — and should be,
because it proves the entire platform stack end-to-end *before* the apex flip, turning the
cutover into a DNS/TLS change on a known-good cluster instead of a bring-up and a cutover at
once. What D8 gates is **only** the later move of prod's `BASE_DOMAIN` to the bare apex.
Verify the two guard values live in prod's applied `cluster-vars` before unsuspending; if
`EXTERNALDNS_TXT_OWNER_ID` is not `prod`, STOP — that was the root cause of the incident.
- [ ] **P2. Prod's external-dns publishes under owner `prod`.** Check the logs for a matching hosted
zone (F-DNS1 fail-closed mode: no zone selected ⇒ nothing created — which is safe, but means
the filter was narrowed against instruction). Confirm the new TXT registry entries read owner

## Phase A — bare metal to a joined cluster (Ansible)

network (§4), and SSH + the vaulted `ansible_become_password` in
`inventory/group_vars/k3s_prod/vault.yml` (§5). Ansible cannot escalate on prod without that vault
file. See `infra/PROD-PROVISIONING.md`.
**Install the backports kernel first.** All three prod nodes need ≥6.13 because HP's R21 firmware
publishes a corrupt EFI Memory Attributes Table and Linux 6.12's `efi_memattr_init()` does not
validate it, reserving everything above the table (fixed upstream in 6.13 by `8fbe4c49c0cc`, absent
from `linux-6.12.y`). Prod runs `7.1.8+deb13-amd64` from trixie-backports.

```
Then the full chain — baseline, k3s HA, Cilium, verify, Flux hand-off. **All three `-e` flags are

```
## Phase B — Flux bootstrap
`flux-bootstrap.yml` (last play of `site.yml`) shells to `bootstrap/flux/bootstrap.sh`, the single
documented entrypoint. That script now runs the CRD pre-apply as step **[2/4]**, so a cold bootstrap
no longer strands `platform`. The **age private key Secret must exist first** — bootstrap verifies it
and refuses to continue rather than silently skipping decryption
(`bootstrap/sops/age-key-secret.md`).
## Phase C — bring the reconciliation graph up
One script, six steps, each independently runnable and idempotent. **Run them in this order.**
```bash
K=infra/ansible/.cache/prod.kubeconfig
S=https://192.168.2.9:6443
```
### C1 — preflight (read-only, changes nothing)
Asserts the guards that prevent a repeat of the DNS incident and reports every tier's state. **Fails
closed** if `EXTERNALDNS_TXT_OWNER_ID` is empty, still the base sentinel, or `default` (dev's owner).
```bash
timeout 300 infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig infra/ansible/.cache/prod.kubeconfig --expect-server https://192.168.2.9:6443 preflight
```
### C2 — pre-apply chart CRDs, and break the CDI cold-start deadlock (idempotent)
```bash
timeout 600 infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig infra/ansible/.cache/prod.kubeconfig --expect-server https://192.168.2.9:6443 crds
```
Two cold-start problems, same root cause: **Flux server-side dry-runs every object in a Kustomization
before applying any of them, so one unknown `kind` aborts the entire tier.**
1. **Kyverno** — its ~5.6 MiB CRD bundle exceeds kubectl's 256 KiB annotation limit, so the chart sets
`crds.install: false` and nothing else installs them. `bootstrap/flux/preapply-crds.sh` applies them
server-side, deriving the version from the HelmRelease Flux reconciles (no second pin).
2. **CDI — a true deadlock.** `platform-config` applies the CDI CR *and*
`platform/kubevirt/cdi-storageprofiles.yaml` in the **same pass**. But `StorageProfile`'s CRD does
not exist until `cdi-operator` has reconciled that CR. So the dry-run fails on the unknown kind →
the CR is never applied → the CRD is never created → `platform-config` can never converge, and
every tier below it stays blocked. **Invisible on an established cluster** (dev's CRDs have been
there for months) **and fatal on a cold one.** Observed on prod 2026-09-05: `cdi-operator`
Available for 12h with **no CDI CR** and no `storageprofiles` CRD.
The step breaks it by applying **only the CR** — the minimum — and leaving everything else to
Flux. It carries no `${}` tokens, so applying it here cannot diverge from what Flux would render.
The CRD appeared in 10s.
**REPAIRED IN THE GRAPH (2026-09-05).** `cdi-storageprofiles.yaml` now lives in its own tier,
`./platform-config-cdi`, with `dependsOn: platform-config` and `wait: true`. Because `dependsOn` is
**revision**-gated and `platform-config` runs `wait: true`, the CDI CR must be applied *and healthy*
— which is precisely the event that creates the `StorageProfile` CRD — before the profiles are
applied. A cold cluster now orders itself. The `crds` step is retained as a fallback for a cluster
already stuck in the broken state, and because it is idempotent.
**The generalisable rule, now recorded in `clusters/README.md`:** a CR whose CRD is created by a
*controller at runtime* is **second-order** and needs its own pass. `cdi-operator.yaml` registers
exactly one CRD (`cdis.cdi.kubevirt.io`); `storageprofiles`, `datavolumes`, `datasources` and
`dataimportcrons` appear only after cdi-operator reconciles the CDI CR. An audit of
`platform-config` found `StorageProfile` is the only second-order kind there.
`apps-vms` gained `dependsOn: platform-config-cdi` — load-bearing, not cosmetic:
`apps/vms/unifi/20-datavolume.yaml` provisions on `storageClassName: longhorn-vm`, and its comment
previously claimed `platform-config` guaranteed the profiles, which the move would have silently
falsified.
#### Merge precondition and the one-time transient
`platform-config` has `prune: true`, so on the first reconcile after merge it **deletes** both
StorageProfiles, CDI recreates them within seconds with an empty spec, and `platform-config-cdi`
re-applies the overrides ~30–60s later (kustomize-controller's dependency requeue).
**Measured on dev, so the exposure is known rather than assumed** — comparing our override against
what CDI infers unaided for the same Longhorn provisioner:
| profile | `spec` (ours) | CDI-derived `status` |
|---|---|---|
| `longhorn-vm` (we override) | RWX / Block, `snapshot` | **ReadWriteMany** / Block, `snapshot` |
| `longhorn-static` (no override) | *unset* | **ReadWriteOnce** / Block, `snapshot` |
So **`cloneStrategy` is not at risk** — CDI infers `snapshot` for Longhorn anyway. **`accessModes`
is:** unaided, CDI produces **RWO**. A DataVolume provisioned on `longhorn-vm` *inside the window*
would be stamped RWO/Block and be **permanently non-live-migratable**. Flux can no longer cause that
(`apps-vms` now gates on the new tier); **do not start a VM disk import, clone or DataVolume by hand
during the window.**
- [ ] **Before merging, confirm `flux get kustomization platform-config` is Ready on the target.** If
it is not, the profiles are pruned and sit at CDI defaults until it recovers — and prod was in
exactly that state hours earlier. The fallback is the two-step the Cilium move used: merge with
`platform-config.prune: false`, confirm the ownership label transferred, restore `prune: true` in
a second commit.
- [ ] After: both profiles carry `spec.cloneStrategy: snapshot`, `longhorn-vm` carries
`claimPropertySets` RWX/Block, and both are labelled
`kustomize.toolkit.fluxcd.io/name=platform-config-cdi`.
### C3 — unwedge stuck Helm releases
A release left in `uninstalling` / `pending-*` cannot be advanced by helm-controller: it reports
`StateError` forever, so `platform` (`wait: true`) never goes Ready and all 10 tiers below it stall.
**Dry run by default** — it prints what it would do and changes nothing:
```bash
timeout 600 infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig infra/ansible/.cache/prod.kubeconfig --expect-server https://192.168.2.9:6443 unwedge
```
To act (this **deletes** the release's Kubernetes objects and lets Flux install cold). Pre-applied
CRDs live **outside** the Helm release and survive, which is exactly why C2 comes first:
```bash
timeout 900 infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig infra/ansible/.cache/prod.kubeconfig --expect-server https://192.168.2.9:6443 \
--confirm-destructive unwedge
```
### C4 — external-dns safe upgrade
**The most dangerous step in the repo, and the ordering is the entire mitigation.** A Helm upgrade
resets `replicas` to the chart default (1) and applies the new args in ONE operation — there is no
window in which to check the result first. If `--txt-owner-id` were missing, the pod starts as owner
`default`, claims dev's TXT registry entries, and under `policy: sync` **deletes the records behind
them**.
So this step **proves the outcome before causing it**: it renders the chart with the *live*
HelmRelease values and asserts `--txt-owner-id=<owner>` appears, aborting if not. Rendering is
deterministic and touches nothing, which converts a race into a precondition. It then snapshots the
Cloudflare zone, upgrades, re-verifies the live args (scaling to 0 and failing if they are wrong),
and diffs the zone.
```bash
timeout 900 infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig infra/ansible/.cache/prod.kubeconfig --expect-server https://192.168.2.9:6443 externaldns
```
Expected diff: **additions only, all under `prod.home.keithjackson.dev`, all TXT entries owner
`prod`.** Any change to a name outside that subtree, or to a TXT entry owned by another cluster, is a
regression — stop and investigate.
### C5 — resume the tiers, in dependency order
`platform → platform-config → {oauth2-proxy, headlamp, homepage, crafty, apps-wave-0, apps-vms} →
apps-wave-1 → apps-wave-2`. Waits for each to go Ready and **stops at the first that does not** — a
partial, understood bring-up beats a forced green. `velero` is skipped while `S3_BACKUP_ENDPOINT` is
a placeholder (see §Blockers). Long-running; expect it to background.
```bash
timeout 3600 infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig infra/ansible/.cache/prod.kubeconfig --expect-server https://192.168.2.9:6443 resume
```
### C6 — verify
```bash
timeout 900 infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig infra/ansible/.cache/prod.kubeconfig --expect-server https://192.168.2.9:6443 verify
```
### Everything at once
Runs C1→C6 with `unwedge` in **dry-run** mode (no `--confirm-destructive`), so it stops short of the
destructive step by design:
```bash
timeout 3600 infra/devcontainer/dev.sh run bootstrap/standup.sh \
--kubeconfig infra/ansible/.cache/prod.kubeconfig --expect-server https://192.168.2.9:6443 all
```

| | |
|---|---|
| Kustomizations | **12/13 Ready** (`velero` deliberately suspended — see §Blockers) |
| Pods | **113 total, 0 not Running/Completed** |
| Wildcard cert | `wildcard-home` **Ready**, Let's Encrypt **prod**, `*.prod.home.keithjackson.dev` |
| Gateway VIP | `192.168.2.20` · crafty L4 `192.168.2.22` · unifi L4 `192.168.2.21` |

| Dev's records | **57, byte-identical to the pre-standup baseline — nothing added, changed or removed** |
End-to-end HTTPS **through the workstation's own resolver — no `--resolve` override, no `-k`** (after
installing the dnsmasq profile below). Every request landed on `192.168.2.20`:
```

gitea. 200 semaphore. 200 grafana. 302 (SSO) pihole. 302
```
The served certificate is prod's own, confirmed by SNI — **not** dev's wildcard, which is what the
resolver bug previously made it look like:
```
subject = CN=*.prod.home.keithjackson.dev
issuer = C=US, O=Let's Encrypt, CN=YR1 (LE production)
SAN = *.prod.home.keithjackson.dev, prod.home.keithjackson.dev
valid = 2026-09-05 .. 2026-12-04
```
Dev, checked in the same pass, still serves `CN=*.home.keithjackson.dev` — **unchanged**.
> Ignore `curl: (91) No OCSP response received` if you pass `--cert-status`: Let's Encrypt retired
> OCSP responders in 2025, so there is nothing to staple. It is not a certificate fault, and the plain
> requests above all validated normally.
### Workstation DNS — install the prod dnsmasq profile
**CORRECTION (operator, 2026-09-05): this is the workstation's own dnsmasq, NOT pfSense.** Earlier
notes in this repo called it a "pfSense override"; that was wrong and the topology below is why.
`/etc/NetworkManager/dnsmasq.d/10-home.keithjackson.dev.conf` (the dev profile) contains:
```
address=/.home.keithjackson.dev/192.168.2.50
```
dnsmasq's `address=` matches the named domain **and every subdomain**, so that one line also captures
the whole `prod.home.keithjackson.dev` tree and answers it with **dev's** address, while Cloudflare
correctly returns prod's `192.168.2.20`.
**Fix — one command, already authored in this repo:**
```bash
sudo infra/workstation/dnsmasq/install.sh
```
It installs `20-prod.home.keithjackson.dev.conf` and reloads the live resolver. dnsmasq resolves
`address=` by **longest match**, so the prod rules win without editing or reordering the dev profile.
Verified against a throwaway dnsmasq loaded with both profiles:
| query | answer |
|---|---|
| `prod.home.keithjackson.dev`, `gitea.prod…`, `keycloak.prod…` | `192.168.2.20` (Gateway) |
| `unifi.prod.home.keithjackson.dev` | `192.168.2.21` (L4) |
| `crafty-mc.prod.home.keithjackson.dev` | `192.168.2.22` (L4) |
| `gitea.home.keithjackson.dev`, `home.keithjackson.dev` | `192.168.2.50` — **dev, unchanged** |
> **Install to `/etc/NetworkManager/dnsmasq.d/`, never `/etc/dnsmasq.d/`.** The standalone
> `dnsmasq.service` is **inactive**; the live resolver is the one NetworkManager spawns
> (`dns=dnsmasq`) with `--conf-dir=/etc/NetworkManager/dnsmasq.d`. A file in the other directory
> changes nothing and looks like it should. `install.sh` pins the destination for exactly this reason.
**Until it is installed, verify prod only with an explicit resolve** — and note *why* this trap is
convincing: dev serves a `*.home.keithjackson.dev` wildcard cert, which matches
`prod.home.keithjackson.dev` (one label), so the prod **apex returns 200 over valid TLS** while
`keycloak.prod.home.keithjackson.dev` (two labels) fails with a certificate-name error. It reads like
a broken prod certificate. It is the wrong server answering.
```bash
curl -sS --resolve gitea.prod.home.keithjackson.dev:443:192.168.2.20 \
https://gitea.prod.home.keithjackson.dev/
```
## NODE MAINTENANCE — draining, rebooting, and the cordon that stops self-healing
Two unplanned node events on 2026-09-05/06 (an ungraceful power-down of prod-3, then a memory upgrade
on prod-2) produced one finding worth more than either incident.
### A failed `kubectl drain` still cordons — and on this cluster a cordon stops storage self-healing
`kubectl drain k3s-prod-2` fails on this cluster with the usual two objections (emptyDir pods,
DaemonSet pods) — **but it cordons the node first, and the cordon persists after the failure.**
Longhorn's `disable-scheduling-on-cordoned-node` is **`true`**, so a cordoned node receives no replica
scheduling. Observed consequence: after prod-2's reboot, **all 17 volumes sat `attached/degraded` with
prod-2 holding 2 of 18 replicas and ZERO rebuilds in flight.** Nothing was driving recovery, every pod
was `Running`, and no alert fired. `kubectl uncordon` started the rebuilds immediately; they converged
17/17 healthy in ~6 minutes.
**So: after any drain — successful or not — `kubectl uncordon <node>` is not tidying up, it is what
re-enables storage redundancy.** Check `kubectl get nodes -o custom-columns=N:.metadata.name,\
U:.spec.unschedulable` before believing a green pod list.
### `drain` cannot complete on this cluster, and the two usual flags do not fix it
`--ignore-daemonsets --delete-emptydir-data` clears the two reported objections and then **hangs
indefinitely**: all three `instance-manager-*` PDBs report **`ALLOWED DISRUPTIONS = 0`** and
`node-drain-policy` is `block-if-contains-last-replica`. Longhorn is refusing to let an
instance-manager be evicted while it runs volume engines. That is data protection, not a bug.
**Requesting replica eviction does not rescue it either:** with **3 nodes and 3 replicas** there is no
fourth node to move a replica to, so eviction can never complete. This is structural, not a setting.
Options, in order of preference:
1. **Just reboot it (cordon, reboot, uncordon).** Proven twice on this cluster: Longhorn resyncs on
return, and `replica-replenishment-wait-interval` is `600`s, so a reboot completed inside ~10
minutes does not even trigger full rebuilds. This is the normal path for firmware, memory or kernel
work.
2. **If the node must be genuinely empty**, first scale to 0 the workloads holding engines on it —
that detaches them, the PDBs go to 1 allowed disruption, and the drain completes. Find them with:
`kubectl -n longhorn-system get engines.longhorn.io -o json` filtered on `.spec.nodeID`.
3. Changing `node-drain-policy` to `always-allow` is **not** advised at 3 nodes/3 replicas — it trades
the protection for exactly the data risk the default exists to prevent.
### Check the kube-vip leader before rebooting a server
`kube-vip` holds the API VIP (`192.168.2.9`) via a leader lease, and it is a **DaemonSet** — so
`--ignore-daemonsets` leaves it running and a *drain* does not move the VIP. A **reboot** does: the
lease fails over and `kubectl` blips for a few seconds. Harmless, but do not mistake it for a fault.
Identify the holder: `kubectl -n kube-system logs -l app.kubernetes.io/name=kube-vip-ds | grep -i leader`.
### Post-maintenance checklist
- [ ] `kubectl uncordon <node>` — **and confirm** `.spec.unschedulable` is clear on all three.
- [ ] Longhorn converged: `kubectl -n longhorn-system get volumes.longhorn.io` shows **0 degraded**.
Rebuilds are serial, so allow minutes, and watch rather than assume.
- [ ] Replica symmetry: each node runs the same count
(`get replicas.longhorn.io` grouped by `.spec.nodeID` / `.status.currentState`).
- [ ] All three nodes report full memory — prod's HP firmware publishes a corrupt EFI memattr table and
a wrong kernel silently strands RAM (§0b). `k3s-prod-*` should each show ~`32638256Ki`.
- [ ] Pods: none `Running`-but-not-`Ready`.

## Blockers
### 1. Backups: endpoint DECIDED, but prod cannot reach it — **prod has no backup coverage**
**Operator ruling 2026-09-05: "the S3 backup location is the same as Dev."** Prod's
`S3_BACKUP_ENDPOINT` is now `http://192.168.1.9:9000`, and the `TBD-PROD-*` placeholder is retired.
**It is not reachable from prod.** Measured from a throwaway pod **inside the prod cluster** — not
from the workstation, which proves nothing about pod egress:
```
curl http://192.168.1.9:9000/minio/health/live → connection timed out after 15s
```
**This is expected topology, not a misconfiguration** (operator, 2026-09-05): the k3s prod cluster is
**not behind pfSense**. It sits on the SOHO router network `192.168.2.0/24`, which is pfSense's
**WAN** side; pfSense *contains* `192.168.1.0/24`, the dev LAN where MinIO lives. Prod reaching
`192.168.1.9` therefore means crossing **into** pfSense from its WAN — which requires a deliberate
pfSense rule or port-forward that does not exist. **Operator decision required**, and worth weighing:
a prod backup that lands inside the dev LAN is arguably not off-cluster DR at all.
Re-test with `standup.sh --s3-endpoint http://192.168.1.9:9000 s3check` — it fails closed and says so.
> **Do not confuse this with the SOHO router's inbound NAT.** That router forwards inbound **443** to
> the pfSense WAN address `192.168.2.102` to serve the **existing, non-k3s production environment**,
> which must stay live on 443 until the k3s cutover is deliberately made. Nothing in this runbook
> touches that NAT, and prod's Gateway on `192.168.2.20:443` does not contend with it.
Until that routing exists, `velero` stays suspended and **`apps-wave-0` still applies GREEN** — the
token *is* defined, so strict substitution succeeds — while every write to that endpoint fails at
**runtime**. A green `apps-wave-0` does not mean backups work. **Treat prod as having no backup
coverage.**
#### Sharing one MinIO is only safe because of two new knobs
Nothing about the backup *paths* was per-environment before 2026-09-05. Enabling prod against dev's
MinIO without these would have been the external-dns incident again, in a worse place:
| | before | after |
|---|---|---|
| Velero | `bucket: velero`, **no prefix**, both clusters run schedules named `daily` | `prefix: ${VELERO_BACKUP_PREFIX}` — dev `""`, prod `prod` |
| CNPG | `destinationPath: s3://cnpg`, serverName defaults to the **Cluster name** | `${CNPG_BACKUP_PATH}` — dev `s3://cnpg`, prod `s3://cnpg/prod` |
- **Velero** syncs backups it finds in its BSL into itself as `Backup` CRs and **garbage-collects them
when their TTL expires**. Prod would have adopted dev's backups and deleted them on schedule.
- **CNPG is the worse one.** Both environments have `keycloak-db`, `nextcloud-db` and `semaphore-db`,
so prod's Postgres would archive WAL into the *exact prefix* dev's does. Two servers interleaving
WAL into one Barman stream **corrupts the chain and destroys PITR** — and dev's restore is
**proven** (R-STATE-03).
**The base values are dev's current layout on purpose and must stay that way.** Dev's existing
backups live at the bucket root and at `s3://cnpg`; giving dev a prefix would **orphan the very
backups its proven restore depends on** — the same reasoning that keeps dev's
`EXTERNALDNS_TXT_OWNER_ID` at `default`. Prod has no history to preserve, so it takes the nested paths.
> **Delivery note.** Prod reconciles the bootstrap Gitea's `main` at `c8c1d29`. This change sits on a
> later branch that also carries the DNS inversion, which must **not** reach prod (it would move prod
> to the apex and collide with dev). Delivering it needs a `c8c1d29`-based branch carrying only these
> commits. No urgency: velero cannot be enabled until the routing above is fixed.
### 2. Prod is on `prod.home.keithjackson.dev`, not the apex
The operator's target layout is dev under `*.dev.home.keithjackson.dev` and prod on the **apex**.
Prod cannot take the apex until dev vacates it, because both clusters would request a
`letsencrypt-prod` wildcard for the *same name set* and race each other's `_acme-challenge` TXT
records, so neither reliably solves DNS-01.
**This does not block phase C.** Prod on its own subtree with `txtOwnerId: prod` collides with
nothing, and standing it up first is strictly better: it proves the whole stack before the flip, so
the cutover becomes a DNS/TLS change on a known-good cluster instead of a bring-up and a cutover at
once. The apex move is `infra/PROD-PROVISIONING.md` §10a, sequence **D** (dev vacates) then **P**.
> **THE APEX FLIP IS ALSO THE LEGACY-PROD CUTOVER — they are the same event.** The SOHO router NATs
> inbound **443** to the pfSense WAN address `192.168.2.102`, serving the **existing, non-k3s
> production environment**, which the operator requires to stay live until the switch is deliberately
> made. So §10a sequence **P** is not merely a DNS/TLS change on the k3s side: taking
> `home.keithjackson.dev` means public traffic must also stop resolving to / being forwarded to the
> legacy stack. Sequence **P** as written does **not** cover repointing that NAT, and the two must be
> planned together or the apex will resolve to k3s while inbound 443 still lands on the legacy box.
>
> Nothing in phase C touches it: prod's Gateway is `192.168.2.20:443`, a different address from the
> NAT target, and prod's wildcard cert is issued by **DNS-01**, which needs no inbound 443 at all.

## Not covered here
- **Dev's migration off the apex** — §10a sequence D. Touches Keycloak's issuer, ~12 OIDC client
redirect URIs, and a rolling k3s restart that invalidates every OIDC kubeconfig. Operator-present.
- **Prod's GitOps cutover** (P5) from the workstation bootstrap Gitea to prod's own in-cluster Gitea.
`clusters/prod/kustomization.yaml` owns that procedure.
- **Six L2 conformance tests hardcode the apex** and must be parameterized per environment before
§9's "suite passes green against the prod cluster" can be claimed.

### Two API addresses, split 2026-09-06 — do not re-merge them
`k3s_api_host` and `k3s_apiserver_endpoint` were one variable, and the conflation put every
prod `cilium-agent` on `192.168.2.10` (`k3s-prod-1`'s own address) on a cluster whose point is
HA — verified live. Lose that node and the datapath keeps serving from Cilium's cache while no
service or policy update ever lands, which is a silent failure, not an outage.
| variable | value | consumed by | why it must be that address |
|---|---|---|---|
| `k3s_api_host` | the founder's own node IP (dev `192.168.1.50`, prod `192.168.2.10`) | `roles/k3s_server`: the secondary `--server https://…:6443` join URL, and one `k3s_tls_sans` entry | on a **cold** build no VIP exists yet (kube-vip is a k3s auto-deploy manifest, so it needs a cluster first). The founder just ran `--cluster-init` and is up |
| `k3s_apiserver_endpoint` | `{{ kube_vip_address }}` (dev `192.168.1.49`, prod `192.168.2.9`) | `roles/cilium` → `k8sServiceHost`; any steady-state client | it must survive losing any single server |
Consequences already handled: `playbooks/site.yml` imports `kube-vip.yml` **between** `k3s.yml`
and `cilium.yml` (the VIP has to be floating before the CNI dials it), and `roles/kube_vip`'s
last task blocks until the VIP answers on 6443. `k3s_tls_sans` already carried both addresses,
so no cert reissue and no k3s restart are involved.
The Flux side of the same contract is `${K3S_API_HOST}` in `platform/cilium/helmrelease.yaml`,

# --cluster-init), which is the whole reason this variable is the founder.
# 2. roles/k3s_server — one entry of k3s_tls_sans, so the founder's own address is a SAN
# alongside the VIP and every other server's IP.

# What IS wrong is that any timestamp a node renders in LOCAL time — journald's default
# output, `ls -l`, a shell prompt, an etcd snapshot filename — cannot be compared across
# nodes without knowing each node's zone. Correlating three nodes' logs during an incident
# is exactly when nobody has that knowledge to hand, and this cluster took two unplanned
# node reboots in the 24h before this was written.
#
# WHY UTC AND NOT "STANDARDISE ON CENTRAL". Picking one local zone leaves the class of
# problem intact (a fourth node, or a DST boundary, re-creates it) and adds a translation
# step to every log read, because every timestamp the PLATFORM emits — Kubernetes events,
# Prometheus, Loki, Velero, CNPG WAL, the etcd snapshot annotations above — is already UTC.
# UTC removes the class: node-local time and platform time become the same clock, and there
# is no DST discontinuity in which a repeated or skipped hour breaks log ordering. This also
# matches the only timezone convention the repo already had — catalog/plex.yaml records
# "no other service in the repo sets a timezone ... so use the safe default" and both it and
# apps/wave-0/plex.yaml set TZ=Etc/UTC. (platform/crafty sets America/Chicago, deliberately:
# that is a USER-FACING game server's schedule, not a node's log clock.)
#
# WHY A KNOB AT ALL (R-ENV-02). The value is a node-level Ansible fact, so its override seam
# is inventory/group_vars/<env>, NOT clusters/base/cluster-vars.yaml (a Flux postBuild
# ConfigMap no Ansible code reads) — the same seam node_baseline_backports_kernel and
# node_baseline_dns_servers use. NO ENVIRONMENT OVERRIDES IT TODAY, and one should not have
# to: dev and prod both want UTC and there is nothing environment-specific about a node
# clock. It is a variable rather than a literal in the task so a genuinely

## Choosing a cluster — `CLUSTER=dev|prod`
```bash
./dev.sh run kubectl get nodes # DEV — the default, unchanged
CLUSTER=prod ./dev.sh run kubectl get nodes # PROD
CLUSTER=prod ./dev.sh # interactive shell pointed at prod
```
An env-var **prefix**, so the target sits on the same line as the command. Every invocation prints
a banner naming the cluster before the container starts, because `CLUSTER` can also be inherited
from an exported shell variable.
Inside the container `KUBECONFIG` points at a **merged** config holding both clusters under
unambiguous names, with `CLUSTER`'s context current:
```
CURRENT NAME CLUSTER AUTHINFO
* k3s-dev k3s-dev k3s-dev-admin
k3s-prod k3s-prod k3s-prod-admin
```
So `kubectl config current-context` answers "which cluster am I on?" honestly, and
`kubectl --context k3s-prod …` works from a dev-defaulted shell.
**Why a merge script and not `KUBECONFIG=dev.kubeconfig:prod.kubeconfig`.** k3s names the context,
the cluster *and* the user in **both** files `default`. kubectl's merge keeps the **first**
occurrence of a duplicated name, so a colon-joined `KUBECONFIG` silently resolves `default` to
**dev** and `--context default` can never reach prod — you would believe you were on prod while
issuing commands against the live dev cluster. `kubeconfig.sh` therefore **renames on merge**
(`k3s-dev` / `k3s-prod`, `*-admin` users) with `yq`, structurally — not with `sed`, which corrupts
these files because the cluster and the user entry are both `- name: default` at identical indent.
- Generator: [`kubeconfig.sh`](kubeconfig.sh). Output: `infra/ansible/.cache/clusters.kubeconfig`,
mode 0600, **regenerated on every `dev.sh run`** — a build artifact, never hand-edited, never
committed (`.cache/` and `*.kubeconfig` are both gitignored; it embeds cluster-admin certs).
- A cluster whose source kubeconfig is missing is simply omitted from the merge, so a machine with
only `dev.kubeconfig` still works.
- **Asking for a cluster whose kubeconfig is absent is a hard error.** `dev.sh` refuses on the host
before starting a container and never falls back to the other cluster — that fallback is exactly
how a prod command lands on dev.
- `bootstrap/standup.sh` is unaffected: it exports its own `KUBECONFIG` from the mandatory
`--kubeconfig` flag, which overrides what `dev.sh` sets. Its `--expect-server` guard remains the
thing that makes it safe, not `CLUSTER`.
### `DEV_KUBECONFIG` — superseded, still honoured
`DEV_KUBECONFIG=<path> ./dev.sh run …` still pins `KUBECONFIG` verbatim and takes precedence over
`CLUSTER` (nothing depending on it breaks), but it is **deprecated**: the name says "dev" while the
established workaround set it to a *prod* path, and it produces a single-cluster config whose
context is the ambiguous `default`. Use `CLUSTER=dev|prod`. Invocations that use it print a warning.

## kubectl inside the container — known gap
## kubectl inside the container — was a known gap, now fixed
`dev.sh` sets `KUBECONFIG` to `/work/infra/ansible/.cache/dev.kubeconfig`, a **libvirt-era path
that no longer exists**, and does not mount `~/.kube`. Override it explicitly:
`dev.sh` used to hard-wire `KUBECONFIG` to `dev.kubeconfig` with no supported way to reach prod, and
it does not mount `~/.kube`. It now selects between `infra/ansible/.cache/dev.kubeconfig` and
`prod.kubeconfig` via `CLUSTER=dev|prod` (see above) and merges both under distinct context names.
```bash
DEV_KUBECONFIG=/work/path/to/break-glass.kubeconfig ./dev.sh run kubectl get nodes

Use a **break-glass cert kubeconfig**, not the `k3s-oidc` context — OIDC login needs a browser,
which a container shell does not have. See [`../PHASE1-STATUS.md`](../PHASE1-STATUS.md) for both
access paths. (Not yet fixed in `dev.sh`.)
The container still needs a **break-glass cert kubeconfig**, not the `k3s-oidc` context — OIDC login
needs a browser, which a container shell does not have. See

#
# INSTALL TO: /etc/NetworkManager/dnsmasq.d/20-prod.home.keithjackson.dev.conf
# NOT /etc/dnsmasq.d/ — the standalone dnsmasq.service is INACTIVE on this workstation. The live
# resolver is the one NetworkManager spawns (NetworkManager.conf `dns=dnsmasq`), and it reads
# ONLY --conf-dir=/etc/NetworkManager/dnsmasq.d. A file dropped in /etc/dnsmasq.d/ changes nothing
# and looks like it should — verify with: pgrep -a dnsmasq
#
# WHY THIS FILE EXISTS
# The dev profile (10-home.keithjackson.dev.conf) contains:
# address=/.home.keithjackson.dev/192.168.2.50
# dnsmasq's `address=` matches the named domain AND EVERY SUBDOMAIN, so that one line also
# captures the entire `prod.home.keithjackson.dev` tree and answers it with DEV's address. Every
# prod hostname therefore resolved to dev from this workstation, while Cloudflare correctly
# returned prod's gateway.
#
# That failure is deceptive because it PARTIALLY works: dev serves a `*.home.keithjackson.dev`
# wildcard certificate, which matches `prod.home.keithjackson.dev` (one label) — so the prod apex
# returns 200 over valid TLS — but NOT `keycloak.prod.home.keithjackson.dev` (two labels), which
# fails with a certificate-name error. It reads like a broken prod certificate. It is not; it is
# the wrong server answering. NEVER verify prod's DNS or TLS through this workstation's resolver
# without confirming these rules are installed.
#
# dnsmasq resolves `address=` by LONGEST MATCH, so the more specific rules below win over the dev
# line without editing or reordering it. The dev profile stays untouched.
#
# TOPOLOGY (corrected 2026-09-05 by the operator — the earlier "pfSense override" framing was wrong)
# The k3s prod cluster is NOT behind pfSense. It sits on the SOHO router network,
# 192.168.2.0/24, which is pfSense's WAN side; pfSense contains 192.168.1.0/24 (the dev LAN).
# This workstation is on 192.168.2.0/24 too, so it reaches prod's VIPs DIRECTLY — no NAT hop,
# which is why these addresses are prod's real VIPs and not a forwarded address like dev's
# 192.168.2.50.
#
# The SOHO router NATs inbound 443 to the pfSense WAN address (192.168.2.102) to serve the
# EXISTING, NON-K3S production environment. That NAT is untouched by this file: these rules are
# local to this workstation's resolver only and change nothing about inbound traffic. The legacy
# prod stays live on 443 until the k3s cutover is deliberately made.
# The prod cluster's shared ingress Gateway (Cilium LB-IPAM; == CILIUM_LB_POOL_START).
# Covers the apex and every service hostname not overridden below.
address=/prod.home.keithjackson.dev/192.168.2.20
# L4 (non-HTTP) services get their OWN LoadBalancer VIPs, so they must NOT be sent to the Gateway.
# These are longer matches than the line above and therefore take precedence.

# platform-config-cdi — the SECOND-ORDER config wave: custom resources whose CRD is created at
# RUNTIME by a controller that a `platform-config` custom resource switches on.
#
# ── THE BUG THIS DIRECTORY EXISTS TO FIX (observed on PROD, 2026-09-05) ───────────────────────────
# The repo already splits CONTROLLERS (`platform`) from CONFIGS (`platform-config`) because a CR
# cannot be dry-run before its CRD is registered. That split assumes a CRD is registered by the
# controller INSTALL. CDI breaks the assumption: `cdi-operator.yaml` registers exactly ONE CRD
# (`cdis.cdi.kubevirt.io`). Every OTHER CDI CRD — `storageprofiles`, `datavolumes`, `datasources`,
# `dataimportcrons`, … — is created by cdi-operator only AFTER it has reconciled the `CDI` CR.
#
# So `cdi-cr.yaml` is a FIRST-order CR (its CRD comes from the install) and belongs in
# platform-config, while `cdi-storageprofiles.yaml` is a SECOND-order CR (its CRD comes from
# reconciling the first-order CR). Having both in ONE Flux Kustomization is a true DEADLOCK, not a
# race: kustomize-controller server-side dry-runs EVERY object before applying ANY of them, so the
# unknown `StorageProfile` kind aborts the whole pass → the `CDI` CR is never applied → the
# StorageProfile CRD is never created → platform-config can NEVER converge, and every tier that
# dependsOn it stays blocked forever. On prod, cdi-operator sat Available for 12h with no CR:
#
# StorageProfile/longhorn dry-run failed: no matches for kind "StorageProfile"
# in version "cdi.kubevirt.io/v1beta1"
#
# Invisible on dev (whose CDI CRDs have existed for months) and fatal on any COLD cluster.
#
# ── THE RULE, so this is not rediscovered a third time ────────────────────────────────────────────
# A CR belongs HERE (not in platform-config) when the CRD it needs is created by a CONTROLLER AT
# RUNTIME rather than by a manifest in git. Grep test: if `grep -rn "kind: CustomResourceDefinition"`
# over ./platform (following remote bases) does not produce the CRD, and no chart installs it, then
# some operator creates it after being switched on — and this is the tier for it.

# set-r2-credentials.sh — put ONE Cloudflare R2 API token into every credential Secret that consumes
# the off-cluster backup target, without plaintext ever touching the disk.
#
# WHY THIS EXISTS
# The same S3 key is read by four different Secrets in three namespaces, in TWO different shapes
# (Velero wants an AWS INI file; CNPG/barman wants discrete ACCESS_KEY_ID / ACCESS_SECRET_KEY keys).
# Hand-editing four SOPS files is four chances to typo one of them — and a typo'd backup credential
# does not fail at apply time, it fails at 03:00 with no backup and a green HelmRelease.
#
# It uses `sops set`, which edits an ALREADY-ENCRYPTED file in place: the new value is encrypted as
# it is written and NO decrypted copy of the file is ever created. That is the whole point — the
# `cp template plaintext.yaml && edit && sops -e -i` dance leaves a plaintext Secret sitting in the
# working tree, one `git add -A` away from being committed forever.
#
# USAGE (inside the dev container — it has sops and mounts the age key)
# ./infra/devcontainer/dev.sh run platform/backup/set-r2-credentials.sh
# → prompts for the two values (never echoed, never in shell history, never in a file)
#
# ./infra/devcontainer/dev.sh run platform/backup/set-r2-credentials.sh --check
# → touches nothing; just reports whether the four Secrets already agree with each other
#
# R2_ACCESS_KEY_ID=… R2_SECRET_ACCESS_KEY=… …/set-r2-credentials.sh --no-prompt
# → non-interactive. Prefer the prompts: an env var is visible in /proc and in `history`.
#
# WHAT IT DOES NOT DO
# - It does not touch clusters/base/cluster-vars.yaml. The endpoint is not a secret and belongs in
# a reviewable plain manifest; the script prints the exact edit to make.
# - It does not commit. Review `git diff` (you will see only ENC[...] blobs change) and commit.
# - It does not delete or rewrite platform/backup/minio-credentials.sops.yaml. That is the RETAINED
# pre-migration MinIO key and it is what you need to read the pre-migration backups.

## Controller-generated pods (who sets the labels when git cannot)
`egress-class` / `auth-mode` are normally projected onto pod templates by the renderer (below).
Some pods are generated by a **controller at runtime** and therefore have no manifest in git to
label — CDI's `importer-*` / `uploader-*` / `cloner-*` worker pods are the live example: both
label policies denied CDI's importer on prod (2026-09-06) and the UniFi VM got no disk. For those,
`policies/label-cdi-worker-pods.yaml` **adds** the labels at admission (`+(…)` add-if-absent),
matched on the **generating ServiceAccount** (`cdi/cdi-sa`) — never on a pod-name prefix or on
CDI's own labels, both of which any pod author in the namespace can copy. `virt-launcher-*` needs
nothing: KubeVirt propagates the VM pod-template labels onto it (verified on dev).

# Serves: R-NET-05 (egress is a declared property) + R-IDP-02 (auth mode is declared) —

# CANNOT carry the labels from git SATISFY them, instead of being exempted from them.
#
# THE DEFECT IT FIXES (observed on LIVE prod, 2026-09-05/06):
# `DataVolume unifi/unifi-rootdisk` sat in ImportScheduled for hours holding a detached
# 40Gi `prime-…` scratch PVC. `kubectl -n cdi logs deploy/cdi-deployment` showed:
# admission webhook "validate.kyverno.svc-fail" denied the request: resource
# Pod/unifi/importer-prime-<uid> was blocked due to the following policies
# require-auth-mode-label / require-egress-class-label
# CDI generates its own short-lived worker pods (importer-*, uploader-*, cloner-*/
# clone-source-*) from inside the cdi-deployment controller. Those pods are not in git,
# so nothing can put the platform labels on them, and both label policies match ANY Pod
# in a namespace labelled homelab.keithjackson.dev/app-namespace=true. Result: the VM
# never gets a disk. This is a COLD-START defect, not a prod quirk — dev's identical
# import Succeeded before the policies were enforcing, so dev has never exercised it and
# would hit it on any rebuild.
#
# WHY MUTATE (and not an exception/exclusion):
# The honest reading of R-NET-05/R-IDP-02 is "every pod's egress path and auth posture is
# DECLARED". A CDI importer pod has truthful values for both:
# egress-class: internet — it pulls the image from the public internet over https
# (cloud-images.ubuntu.com / quay.io) and must take the
# default WAN path, which is exactly what Cilium's egress
# gateway does for `internet` (ADR-0013/ADR-0015). It is NOT
# a `vpn` workload.
# auth-mode: none — the pod serves no UI and terminates when the import ends;
# there is nothing to put an IdP in front of. docs/13 permits
# `none` for internal, non-public workloads (the
# ServiceDefinition policy forbids only public + none).
# So the requirement is SATISFIED rather than bypassed: the invariant "every pod in an app
# namespace carries both labels" stays literally true cluster-wide, both label policies
# stay untouched (no `exclude`, no PolicyException, background scanning still on), and the
# labels are functional — the pod is now selectable by the Cilium egress fabric instead of
# being an unlabelled pod that silently falls through to the default path.
#
# THE MATCH IS THE GENERATING ServiceAccount, NOT A NAME PREFIX:
# `subjects: ServiceAccount cdi/cdi-sa` is the identity in the AdmissionReview's userInfo —
# the controller that issued the CREATE. Verified on prod from the Kyverno admission log of
# the blocked request:
# user={"username":"system:serviceaccount:cdi:cdi-sa", ...} roles=["cdi:cdi-deployment"]
# name=importer-prime-be3f9d1c-… namespace=unifi operation=CREATE
# A pod NAME (`importer-*`) or CDI's own labels (`cdi.kubevirt.io`) are attacker-CHOOSABLE:
# anyone who can create a pod in the namespace can name it `importer-prime-x` and copy the
# labels, and would then inherit the exemption. The requesting ServiceAccount cannot be
# chosen by the pod author — only by someone who already holds cdi-sa's token, which already
# confers "create any pod in any namespace" cluster-wide. So this adds no reachable
# privilege. It is also VERSION-ROBUST: it covers every CDI worker kind (importer, uploader,
# cloner/clone-source) without enumerating names that change between CDI releases —
# confirmed on prod that cdi-sa is the ONLY cdi-namespace ServiceAccount that can create
# pods (`kubectl auth can-i create pods -n unifi --as …`: cdi-sa yes; cdi-apiserver no;
# cdi-uploadproxy no).
#
# DELIBERATELY NOT COVERED — KubeVirt's own generated pods:
# virt-launcher-* pods INHERIT the VM's pod-template labels, so a VM authored in this repo
# already passes (verified on dev: virt-launcher-unifi-22dg7 carries egress-class=internet,
# auth-mode=native from apps/vms/unifi/30-virtualmachine.yaml). Exempting
# kubevirt-controller would REMOVE that useful enforcement on VM authors, so it is not done.
# KubeVirt's hotplug (`hp-volume-*`) and export (`virt-export-*`) pods do NOT inherit those
# labels, but nothing in this repo uses volume hotplug or VirtualMachineExport; if either is
# adopted, extend this policy then — with the same ServiceAccount-scoped shape.
#
# OPERATOR NOTE — this is the cluster's FIRST resource-MUTATING policy. Verified on prod
# 2026-09-06 that `kyverno-resource-mutating-webhook-cfg` currently holds 0 webhooks; with the
# chart's `autoUpdateWebhooks=true` Kyverno registers `mutate.kyverno.svc-fail` for Pods within
# seconds of this policy being applied. Prod runs `forceFailurePolicyIgnore=false`, so that
# webhook is failurePolicy: Fail — the same posture as the validating webhook that is ALREADY in
# the path for these pods, so no new fail-open surface and no new blocking surface. CDI retries
# the importer pod on a loop, so the stuck import proceeds once the policy lands (the detached
# `prime-…` scratch PVC left behind by the blocked attempts is a separate operator cleanup).
#
# RESIDUAL TRADE-OFF (state it plainly, it is reversible by deleting this file):
# Anything created by `cdi:cdi-sa` in an app namespace now gets `egress-class: internet` +
# `auth-mode: none` supplied for it instead of being rejected for not declaring them. Whoever
# holds cdi-sa's token can therefore run a pod in an app namespace without declaring its egress
# class. That identity can already create arbitrary pods in every namespace (ClusterRole `cdi`:
# pods create/delete cluster-wide), so it is not a new capability — but the declaration is now
# assumed rather than demanded for that one identity. Nothing else changes: the pod is still
# subject to restrict-host-namespaces, the namespace default-deny baseline, and every other
# policy, and `internet` is the LEAST-reach of the two egress classes (it does not grant the VPN
# path).
#
# PROOF (offline, no cluster — platform/kyverno/tests/controller-worker-pods/):
# (a) a CDI importer pod created by cdi:cdi-sa is mutated and then PASSES both policies;
# (b) the SAME namespace's ordinary pod — including one that FORGES the importer name and
# CDI's labels — is NOT mutated and is still DENIED by both policies.

# WHY A SEPARATE SUITE from ../kyverno-test.yaml: a `kyverno test` manifest carries ONE
# `userinfo`, and the whole point here is that the SAME pods get different outcomes for
# different requesters. Two Test documents, two identities, one file:
# 1. cdi-controller-worker-pods-admitted (requester = cdi/cdi-sa) -> mutated, ADMITTED
# 2. cdi-worker-exemption-is-narrow (requester = ordinary user) -> not mutated, DENIED
# Keeping the mutate policy OUT of ../kyverno-test.yaml is deliberate: that suite declares no
# userinfo, and with no userinfo the offline engine does not discriminate on `subjects`, which
# would silently turn its negative (result: fail) rows into passes.

## What this is (LIVE)
Flux `HelmRelease` (Velero chart 12.x / Velero 1.18.x) wired to the on-Proxmox **MinIO** S3 target:
Flux `HelmRelease` (Velero chart 12.x / Velero 1.18.x) wired to whatever `${S3_BACKUP_ENDPOINT}` names.
The target is a **cluster-vars knob, not a constant**:
- **Endpoint:** `http://192.168.1.9:9000` (plain HTTP, **path-style**, region `us-east-1` placeholder)
- **BucketStorageLocation `default`:** provider `aws`, bucket `velero`, `s3ForcePathStyle=true`.
- **AWS plugin** (`velero/velero-plugin-for-aws`) loaded as an init container.
- **Endpoint:** `${S3_BACKUP_ENDPOINT}` — dev has been running against the on-Proxmox **MinIO**
`http://192.168.1.9:9000`; as of **2026-09-05** the authored target is **Cloudflare R2**
(`https://<account-id>.r2.cloudflarestorage.com`). The switch-on procedure, the R2 gotchas and the
honest proven/unproven split all live in **[`infra/BACKUP-R2.md`](../../infra/BACKUP-R2.md)**.
Always **path-style**; region `${S3_BACKUP_REGION}` (MinIO ignores it, R2 requires exactly `auto`).
- **BucketStorageLocation `default`:** provider `aws`, bucket `velero`, prefix
`${VELERO_BACKUP_PREFIX}` (dev/prod — both clusters share one R2 endpoint and are isolated by path
only), `s3ForcePathStyle=true`, **`checksumAlgorithm: ""`**.
That last one is load-bearing: `velero-plugin-for-aws` v1.14.2 defaults it to `CRC32` and R2 rejects
AWS checksums with HTTP 400 `InvalidArgument`. Do not remove it, and re-check it on every plugin bump.
- **AWS plugin** (`velero/velero-plugin-for-aws:v1.14.2`) loaded as an init container.
- **File System Backup (kopia):** `deployNodeAgent=true`, `uploaderType=kopia`, `snapshotsEnabled=false`
— storage-agnostic PVC backup, **no** CSI snapshot / data-mover.
— storage-agnostic PVC backup, **no** CSI snapshot / data-mover. This path uploads through kopia's
**own** S3 client, which does not read `checksumAlgorithm`: metadata compatibility and volume-data
compatibility with a given object store are two separate questions.
- **Credentials:** `velero-cloud-credentials` — a SOPS Secret (`velero-cloud.sops.yaml`) holding the
`cloud` INI key, the **scoped** MinIO key limited to the `velero`+`cnpg` buckets. Kept in sync with
the staging source of truth `platform/backup/minio-credentials.sops.yaml` and the Proxmox host
ansible-vault.
`cloud` INI key, the **scoped** key limited to the `velero`+`cnpg` buckets. Four Secrets across three
namespaces hold this one key; `platform/backup/set-r2-credentials.sh` writes all four at once with
`sops set` (no plaintext ever on disk) and proves they agree.
`platform/backup/minio-credentials.sops.yaml` retains the **pre-migration MinIO** key — that is
deliberate, it is how the pre-migration backups stay readable.
## Proving the target before trusting it
```bash
bootstrap/standup.sh --kubeconfig <kc> --expect-server <url> \
[--s3-endpoint <candidate>] s3check
```
`s3check` runs a throwaway in-cluster pod per credential and proves credential load + authentication,
bucket existence and listability under this environment's prefix, and a real
**PUT → GET → byte-compare → DELETE → confirm-gone** round trip — plus whether the R2 checksum trap is
present. It fails closed and loud; it never reports "unknown, carrying on". Pod egress is the only
reading that counts (prod sits on pfSense's WAN, the MinIO inside its LAN).
Reconciled by its **own non-gating** Flux Kustomization `clusters/base/backup.yaml`
(`dependsOn: platform-config`, `wait:false`) — a backup controller must never gate the platform graph.
