jakman85andClaude Opus 5 e6f6e4febb feat(ci): detect Gitea settings drift -- the blind spot that hid a month of outage
gate / gate (pull_request) Successful in 1m34s
gate / conformance (pull_request) Has been skipped
Every check in this repo reads the repository, the rendered manifests, or the cluster.
NONE could see Gitea's own database, and that is where branch protection and runner
registration live. Three failures came out of that blind spot on 2026-09-29, all the same
shape -- a setting that READ as enforced while not being, with nothing able to notice:

  * main had NO branch protection for ~a month while DECISIONS-LOG recorded it as a
    required status check;
  * ZERO Actions runners were registered, so PR #1 -- the first PR this repo ever had --
    sat pending for 30.6 minutes with nothing to execute it;
  * after enable_status_check and required_approvals were turned on they STILL did not
    bite, because block_admin_merge_override was false: PRs #5-#9 merged with zero
    approvals recorded against required_approvals: 1.

infra/gitea/*.sh ASSERT the desired state. Nothing DETECTED drift from it. This is the
detector.

ci/gitea-settings.sh runs as a merge-gate stage: it diffs the live rule at
/branch_protections/main against infra/gitea/expected-branch-protection.json and asserts at
least one runner is online. It reads the RULE object, not /branches/main -- the branch view
does not expose block_admin_merge_override and showed all-green while the rule was
overridable by the only account that merges.

Verified by test, not assumed:
  no token            -> exit 3, skips loudly, does NOT block
  live == declaration -> exit 0
  injected drift      -> exit 1, blocks, naming both the drifted key and the runner count

The skip is DELIBERATELY not in gate.sh's strict-skips loop. Making an absent credential
block every PR is precisely the lock-yourself-out failure this repo keeps walking into, so
a skip denies a PASS (exit 3) and says loudly what is unverified. REQUIRE_GITEA_SETTINGS=true
upgrades it to a block once the token is wired.

gate.yml's `|| [ "$?" -eq 3 ]` tolerance now covers a second stage. That widening is
declared in the file rather than left to be discovered, and it narrows back the moment
REQUIRE_GITEA_SETTINGS is set.

infra/gitea/set-ci-token.sh mints the token and stores it as the repo Actions secret without
ever printing the value.

UNTIL THAT TOKEN EXISTS THIS STAGE SKIPS, AND A SKIPPED DETECTOR DETECTS NOTHING.

jakman85andClaude Opus 5 fcc66c7858 fix(gitea): admins could override the gate -- the enforcement was not enforcing
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.

jakman85andClaude Opus 5 b2d9883958 docs(ci): close out the hardening -- land the scripts, correct a claim that shipped wrong
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.

jakman85andClaude Opus 5 234cc6a71a docs(gitea): a skipped job reports SUCCESS, not pending -- correct the deadlock claim
gate / gate (push) Successful in 1m33s
gate / gate (pull_request) Successful in 1m32s
gate / conformance (push) Has been skipped
gate / conformance (pull_request) Has been skipped
The runner came up on 2026-09-29 and the first CI jobs this repo has ever run went
green, which falsified a claim merged in #2.

MEASURED:
  gate / gate (pull_request)          success   1m58s (PR 1), 1m34s (PR 2)
  gate / gate (push)                  success   1m32s (PR 2 only)
  gate / conformance (pull_request)   success   "Has been skipped"

#2 said listing the conformance context as a required check would deadlock every PR,
because the job is `if: false` and never runs. That is wrong. Gitea reports a skipped
job as SUCCESS. Requiring it would not deadlock anything -- it would pass VACUOUSLY,
forever, while nothing ran.

The conclusion is unchanged (never require it) but the reason inverts, and the corrected
reason matters more: under HARD RULE 4 a permanently-green check that verifies nothing is
worse than a deadlock. A deadlock is loud. This is the exact fail-open shape the
2026-09-18 audit and this one both keep finding.

Also records that the (push) contexts only appear for branches matching gate.yml's push
trigger -- feature/**, fix/**, docs/**, chore/** -- and NOT feat/**, which is why PR 1's
feat/ branch produced only pull_request contexts. Require the pull_request context alone,
or PRs from non-matching prefixes never satisfy the rule.

CLAUDE.md's enforcement table is updated: the runner half is genuinely fixed and observed
green, the branch-protection half is not. Adds the warning that a green tick is not by
itself evidence that anything ran.

jakman85andClaude Opus 5 fe862ab527 infra(gitea): recover the Actions runner before anything requires the gate
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
gate / gate (pull_request) Successful in 1m32s
gate / conformance (pull_request) Has been skipped
No runner is registered at repo, org or site level, so gate.yml has never executed.
PR #1 sat pending for 30.6 minutes across 122 polls and never reported. Requiring the
gate as a status check in that state would lock the repo permanently.

Adds runner-token-rotate.sh: mints a fresh instance-level registration token from the
Gitea API and writes it into the SOPS secret via sops set, without ever printing the
value.

Records the likely root cause, which a new token alone does NOT fix. act_runner
registers once and persists its identity in /data/.runner on the act-runner-data PVC.
If Gitea no longer holds a matching runner row, the pod starts, sees .runner, SKIPS
registration entirely, and polls with an identity Gitea does not recognise. Symptom:
zero runners, pod running, nothing obviously broken. Clearing the PVC is what forces a
genuine re-registration.

The README now sequences runner-first, enforcement-second, and requires CONFIRMING the
runner reports online rather than assuming it. That assumption is the whole defect:
DECISIONS-LOG recorded the runner as online on 2026-08-31 and nobody checked since.

jakman85andClaude Opus 5 a2665c0511 infra(gitea): script the branch protection that was never applied
gate / gate (push) Has been cancelled
gate / conformance (push) Has been cancelled
gate / gate (pull_request) Successful in 1m33s
gate / conformance (pull_request) Has been skipped
Gitea repo settings live in its own database, not in a manifest Flux reconciles, so
they are drift-prone and invisible to the conformance gate -- which is how main came
to accept direct pushes while the log recorded it as protected.

Adds infra/gitea/branch-protection.sh (blocks direct pushes to main) and a README
carrying the measured before-state and the ORDER the remaining steps must happen in.

The script deliberately leaves enable_status_check:false and required_approvals:0.
Both would deadlock today: there is no runner to satisfy a required context, and the
only human account is not yet a repo collaborator, so no one could supply an approval.
The README sequences both.

It prints a push probe to run afterwards. The API response is not proof -- Gitea may
let site admins bypass protection, and that has to be observed, not assumed.
