jakman85andClaude Opus 5 ff0533106b feat(prod): operator decisions — node DNS, service VIPs, become vault, collections path
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
1. PROD NODE DNS = 8.8.8.8 + 1.1.1.1 (operator, 2026-09-01). Two INDEPENDENT public
   upstreams, so the single-upstream SPOF that broke containerd pulls and CoreDNS
   forwarding on dev cannot recur. Prod deliberately differs from dev, which is
   PiHole-first because dev needs the local jackson.lan zone.

   SCOPE CORRECTED IN THE COMMENTS. Three resolvers answer *.home.keithjackson.dev and
   only one is configured here:
     pods  -> CoreDNS -> platform/coredns/coredns-custom.yaml, whose `template` plugin
              answers the WHOLE zone with ${GATEWAY_VIP}. Self-contained in-cluster;
              PiHole is NOT in this path. Prod is already correct (.20).
     LAN   -> PiHole. Not a cluster concern.
     nodes -> THIS FILE.
   The one thing public node DNS breaks: the k3s API SERVER is a node process carrying
   oidc-issuer-url=https://keycloak.home.keithjackson.dev/realms/homelab and reaches the
   issuer through the NODE resolver, so prod would get the PUBLIC record instead of the
   prod Gateway VIP — breaking kubectl OIDC SSO. Dev avoids this only because its node
   resolver IS PiHole. Not blocking (prod has no cluster or Keycloak yet); options are
   recorded in PROD-PROVISIONING.md §4 for the operator to pick.

2. SERVICE VIPs DECIDED: UNIFI_L4_VIP 192.168.2.21, CRAFTY_L4_VIP 192.168.2.22 — the
   first two addresses after GATEWAY_VIP (.20), mirroring dev's .53/.54/.55 ordering
   within the .20-.30 pool. S3_BACKUP_ENDPOINT stays TBD-PROD-* : no prod backup target
   exists, and dev's versitygw is across the pfSense boundary on the dev host, so it is
   not DR for prod.

3. PROD BECOME VAULT committed, ansible-vault encrypted, matching the hypervisor and
   proxmox_hosts pattern. Verified working: `ansible k3s_prod -m command -a 'id -un'
   --become` returns root. The L0 no-plaintext-secrets check asserts every ansible
   vault.yml starts with $ANSIBLE_VAULT, so this stays honest by gate.

4. TOOLCHAIN GAP FIXED: the devcontainer image does NOT ship the Galaxy collections, so
   EVERY ansible play died at parse time on community.general.modprobe. ansible.cfg now
   sets collections_path = collections, and the collections are installed there from the
   existing collections/requirements.yml (gitignored — pinned by requirements, fetched at
   setup, vendored bytes are not source).

5. DRIVE HEALTH MEASURED and recorded in §2 with the raw attribute table so the numbers
   are auditable. Verdict: usable, but not for production etcd/Longhorn state — 31% of
   rated life consumed, 15 grown bad blocks, 187 erase failures, and 32 unexpected power
   losses on a consumer drive with NO power-loss protection, in a single failure domain.
   etcd is the worst possible tenant: it fsyncs constantly and unclean power loss without
   PLP is exactly how a member corrupts.

6. NON-ECC RAM: RISK ACCEPTED by the operator, recorded as a CLOSED decision, not an open
   item — do not re-litigate. Rationale: 3-node k3s homelab, not enterprise; corruption on
   one node is outweighed by the other two and causes node ejection. That holds for the
   dominant mode (etcd raft CRC + quorum; Longhorn 3 replicas + hard anti-affinity +
   rebuild). Recorded residual: corruption introduced UPSTREAM of replication replicates
   faithfully to all three replicas, so quorum sees no disagreement — low probability, and
   the only mitigation is different hardware. Follow-up noted: Longhorn's
   snapshotDataIntegrity is left at the chart default rather than set explicitly, and it
   is the mechanism that operationalises the operator's own argument.

jakman85andClaude Opus 5 c1f24e4a6d fix(dns): resilient node resolvers — mechanism-detecting, per-environment (R-DNS-01/03)
Re-authors the fix stranded on origin/fix/node-dns-resilient-upstream (7a34590). That
commit was NOT landed: it wrote a netplan drop-in and ran `netplan apply`, but netplan
does not exist on these nodes any more (Debian 13 trixie generic cloud image; not in
node_baseline_packages). Landing it would have failed the handler with command-not-found
and BROKEN node-baseline.yml on every node — worse than not landing it. Its dev-LAN
literals also sat in role defaults, which prod inherits, pointing prod nodes at a PiHole
on a network they cannot reach.

The underlying problem is real and verified: a SINGLE upstream resolver is a hard SPOF.
PiHole answers jackson.lan instantly but its external recursion flaps — 0/25 for public
names (registry-1.docker.io, quay.io, ghcr.io) while gitea.jackson.lan resolved 5/5 —
breaking containerd image pulls and CoreDNS `forward . /etc/resolv.conf`.

MECHANISM DETECTION (new `dns` tag in node_baseline). Five read-only probes feed one
set_fact yielding three outcomes, because the two environments no longer share a resolver
stack (dev-1 is behind resolved's 127.0.0.53 stub; prod-1 has a direct resolv.conf and no
cloud-init at all):
  * systemd-resolved — resolved running AND owning /etc/resolv.conf (proven by the
    symlink pointing into /run/systemd/resolve/, or by every nameserver being a resolved
    loopback). Writes resolved.conf.d/99-k3s-dns.conf with an ordered DNS=, Domains=, and
    FallbackDNS= EXPLICITLY EMPTIED so systemd's compiled-in public resolvers can never
    silently bypass the local zone and ad-blocking.
  * resolv-conf-file — plain directly-managed file (prod's shape). Ordered nameserver
    lines + options timeout:2 attempts:2, backup: true. Deliberately NO `rotate`, which
    would destroy PiHole-first ordering.
  * contended — resolvconf/openresolv present or NetworkManager active. Writes NOTHING
    and fails loudly: a change that silently gets reverted is worse than no change.
Resolved-running-but-not-owning-resolv.conf correctly falls through to the file branch.
Ordering is the policy that keeps the local zone working — the second server is only
consulted after the first fails, so a gateway NXDOMAIN can never beat PiHole to a
jackson.lan answer.

SEAMS. Dev values in role defaults ([192.168.1.18, 192.168.1.1], search jackson.lan);
prod values in inventory/group_vars/k3s_prod/vars.yml. NOT cluster-vars — that ConfigMap
is consumed by Flux postBuild for platform/ and apps/, and no Ansible code reads it.

PROD'S SECOND UPSTREAM IS AN OPEN OPERATOR DECISION and is left as a loud
BLOCKED-pending-second-upstream placeholder, the same precedent as the node_baseline disk
devices, with a dns-tagged assert that stops the play before any file is written. A
public resolver was NOT invented as a default: it would bypass the local zone, which is a
decision, not a default. PROD-PROVISIONING.md §4 was rewritten (the old bullet pointed at
the now-dropped branch) to state the choice, including that prod routing to the dev
PiHole is unverified across the pfSense boundary.

tofu: servers = [var.dns_server, var.network_gateway] — the one hunk of the old branch
worth taking as-is. Dev-only by nature.

ALSO FIXES A FALSE WARN THIS WOULD OTHERWISE CREATE: node_health_collect.py parsed
/etc/resolv.conf only, so on dev it read the 127.0.0.53 stub and would report a permanent
single-upstream WARN even after a correct fix. It now asks resolvectl for the real
upstreams when it sees the stub — and if that fails, nameservers is NULL with the reason
recorded, never the stub and never a guess. assess.yml turns null into SKIP, not WARN and
not PASS. The honesty discipline is preserved exactly.

Verified with NO play run against any node: syntax-check + yamllint + tofu fmt clean;
--tags packages still selects ONLY the apt task (the prod package-floor escape hatch
bypasses DNS entirely); --list-hosts unchanged; -c local simulation driving the REAL
detection expression and REAL file bodies extracted from the role by script (so the test
cannot drift) passes all 5 scenarios — dev stub -> systemd-resolved, prod shape ->
resolv-conf-file, NetworkManager and resolvconf -> contended; dev defaults pass the
assert byte-identically while prod overrides fail it by name; collector unit-tested
against 8 resolver shapes.

jakman85andClaude Opus 5 e623d27e2d feat(ansible): parameterise target groups so prod reuses the roles unchanged (R-ENV-02)
roles/k3s_server, roles/cilium and every node-host playbook hardcoded the dev group
names k3s_primary/k3s_secondary/k3s_servers, so the prod inventory groups could not be
selected at all. That broke the R-ENV-02 promise that prod reuses the SAME roles, and
blocked PROD-PROVISIONING.md §6 outright.

TWO KNOBS, deliberately separate — Ansible templates a play's `hosts:` BEFORE any host
context exists, so group_vars is unreadable there, while roles run WITH host context:
  * which hosts a play RUNS ON — k3s_hosts, k3s_primary_hosts/k3s_secondary_hosts
    (k3s.yml's split), vpn_egress_gateway_hosts; each `| default(<dev group>)`, set by -e
    only. Follows node-health.yml's established `<name>_hosts | default(dev)` pattern.
  * which group a ROLE means by "my primary"/"my servers" — k3s_primary_group,
    k3s_servers_group in group_vars/all.yml (dev), overridden in group_vars/k3s_prod.
    Follows the k3s_api_host convention already in this repo. No per-run flag.

DEV IS UNCHANGED — the key evidence. --list-hosts/--list-tasks/--syntax-check captured
for all 9 playbooks at HEAD and after: sorted host lists IDENTICAL for all 9, same
primary/secondary split, same 6-play site.yml. (Raw --list-hosts PRINT ORDER varies run
to run; proven to be Ansible's own set ordering by running UNMODIFIED HEAD cilium.yml
four times -> 3,1,2 / 1,3,2 / 1,2,3 / 1,2,3. Hence sorted comparison.) --list-tasks
differs in exactly two files, only by added TAGS annotations and one new assert; no task
reordered, renamed or removed. Var resolution verified per environment with -c local:
dev -> k3s_primary/192.168.1.50/sans .50,.49,127.0.0.1,.51,.52; prod ->
k3s_prod_primary/192.168.2.10/vip .9/sans .10,.9,127.0.0.1,.11,.12.

BREAKS THE SMARTMONTOOLS CIRCULAR DEPENDENCY. node_baseline tasks are now tagged
packages/system/disks, so the package install can run alone:
  ansible-playbook playbooks/node-baseline.yml -e k3s_hosts=k3s_prod --tags packages
Skipping is the guard — no disks-tagged task is selected, so the
BLOCKED-pending-disk-decision paths are never templated, let alone passed to mkfs.
Belt-and-braces, a new disks-tagged assert fires first in a FULL run and names §2
explicitly instead of failing obscurely at mkfs. `tags: never` was deliberately NOT used
(it would change the default run).

FOOTGUN FOUND AND FIXED: roles/cilium, cluster_verify and flux_bootstrap all hardcoded
.cache/dev.kubeconfig — the exact file infra/devcontainer/dev.sh exports as $KUBECONFIG.
Once prod became targetable, a prod cilium/verify run would have SILENTLY OVERWRITTEN it,
leaving the operator's kubectl quietly answering from PROD. Now cluster_kubeconfig_name
(dev.kubeconfig -> prod.kubeconfig). Dev path byte-identical.

KNOWN, DOCUMENTED, NOT FIXED HERE: flux-bootstrap.yml retargets but roles/flux_bootstrap
shells out to bootstrap/flux/bootstrap.sh with a hardcoded --path=clusters/dev — a
bootstrap/ subtree change, not a target-group change (§6, cross-referenced to §7).
vpn.egress.gateway.yml is parameterised but prod has no egress group yet and would need
its own vaulted PIA credentials. --check against prod is still impossible until the prod
vault exists — even the packages-only run needs it.

Nothing was run against the dev cluster: --list-hosts/--list-tasks/--syntax-check, plus
debug/assert with -c local, only.

Serves: R-ENV-01, R-ENV-02, R-ENV-03. Task: T-7.1.

jakman85andClaude Opus 5 a1fb31a7ef docs(prod): record the decided prod address plan; packages-in-role correction
PROD-PROVISIONING.md §4 now carries the full operator-decided address table (nodes
.10/.11/.12, control-plane VIP .9, ingress Gateway VIP .20, Cilium LB pool .20-.30) with
the two invariants that make it safe: the control-plane VIP sits outside the LB pool so
kube-vip and LB-IPAM cannot contend, and GATEWAY_VIP is the FIRST address of the pool
because the shared Gateway pins nothing and LB-IPAM hands it the first free address.

§5 no longer tells the operator to hand-install smartmontools — package installation is
the node_baseline role's job (operator ruling). §0 gains the node 2/3 addresses.

Task: T-7.1. Gate: MERGE GATE: PASS.

jakman85andClaude Opus 5 e3c44368c8 docs(prod): correct sudo posture to vaulted become; record status-surface ruling
Two operator corrections:

1. PROD DOES NOT GET NOPASSWD SUDO. My initial checklist recommended mirroring dev's
   passwordless sudo onto prod — rejected, correctly. Dev's NOPASSWD is a convenience
   that must not propagate to production. Prod instead keeps a real sudo boundary and
   drives Ansible `become` with an ansible-vault-encrypted `ansible_become_password` in
   inventory/group_vars/k3s_prod/vault.yml, mirroring the EXISTING hypervisor and
   proxmox_hosts groups. The decrypting passphrase stays outside the repo at
   ~/.config/home-k3s/ansible-vault-pass (ansible.cfg :: vault_password_file), so plays
   still run unattended with no plaintext secret in git.

2. THE TASK BOARD IS NOT THE STATUS SURFACE — THE REPOSITORY IS. Operator ruling closes
   the escalation raised in the previous commit. Requirement/spec status is to be DERIVED
   from repo state (what is authored, reconciled, and covered by a green requirement-tagged
   test), not from a hand-maintained board. The spec board is left as a historical seed;
   no agent edits it and no SPEC_PIN churn is spent on it. ci/spec-immutability.sh keeps
   its full strictness — no path exception was added, since weakening an R-TEST-06 gate
   for a bookkeeping file would be a defect, not a fix. A repo-derived spec status report
   becomes the artifact of record alongside the coverage report and this log.

Serves: R-ENV-03 (prod provisioning posture), R-SEC-01 (no plaintext secrets), R-TEST-06.

jakman85andClaude Opus 5 574088dfeb docs(prod): open Phase 7 (prep only) + T-7.1 bare-metal provisioning checklist
The operator added the first production node (k3s-prod-1, 192.168.2.10 — HP EliteDesk
800 G5 Mini, i7-9700T/31GiB, Debian 13, VT-x + /dev/kvm) and opened roadmap Phase 7 for
PREP WORK ONLY: no k3s install until the R-ENV-02 blockers close and the gate is green.

Records the Phase-7 entry-gate position honestly: the operator has declared hardware
ready, but "Phases 1-6 proven in dev/test" is NOT met (37/51 conformance; R-ENV-01/02/03
themselves uncovered). Proceeding is an explicit, accepted risk — not an oversight.

Adds infra/PROD-PROVISIONING.md (T-7.1, design-only): firmware/BIOS, disk layout, OS,
network, access, Ansible reuse, repo blockers, build sequence, Phase-7 exit criteria.

Key findings recorded in DECISIONS-LOG:
- R-ENV-02 is violated in the base — dev LAN addresses hardcoded into base manifests
  (cilium k8sServiceHost, the Cilium LB pool, crafty/UniFi LB IPs, 3 S3 backup
  endpoints). Prod is on 192.168.2.x, so prod would build WRONG today.
- clusters/prod never sets GATEWAY_VIP -> would inherit the base default 10.73.0.240,
  an address on the RETIRED libvirt network.
- No NOPASSWD sudo on the prod node -> all Ansible fails at its first become.
- node_baseline device defaults are virtio (/dev/vdb,vdc) and absent on bare metal.
- ESCALATION: agents/task-board.md is structurally unmaintainable — AGENTS.md designates
  it the one agent-editable surface, but ci/spec-immutability.sh fails the gate on ANY
  spec-repo dirt with no path exception. Explains the all-todo board after six phases.
  NOT worked around: exempting it would weaken an R-TEST-06 gate. Operator decision.

Operator decisions: Phase 7 open (prep only); wait for all 3 nodes before cluster-init;
check drive health before choosing the single-SSD disk layout.

Serves: R-ENV-01, R-ENV-02, R-ENV-03, R-PLAT-01/03. Task: T-7.1.
Gate: MERGE GATE: PASS.
