jakman85andClaude Opus 5 4b31f97486 docs(decisions-log): addendum — detector armed, and why an agent cannot merge here
gate / gate (pull_request) Successful in 1m34s
gate / conformance (pull_request) Has been skipped
Records two findings from the unattended session.

The drift detector was INERT: set-ci-token.sh stored the secret under a name Gitea
reserves (GITEA_ prefix, HTTP 400 "invalid secret name"), sent the PUT to /dev/null,
and printed success anyway. A token existed; no secret did. Enabling
REQUIRE_GITEA_SETTINGS on top of that would have blocked every PR including its own
fix. PR #15 fixes it and its CI is green WITH require active, which is the only
proof that counts.

And: merging as gitea-admin returns HTTP 405 "Does not have enough approvals".
required_approvals:1 + block_admin_merge_override:true + an author who cannot
self-approve means "merge on green CI" is not executable by an agent. Recorded as
the control working rather than a fault, and deliberately not circumvented --
self-approval would hollow out the boundary just built. The choice of what to do
about it is the operator s, and whatever is chosen must also change the declaration
in expected-branch-protection.json or the detector will correctly fail on the drift.

jakman85andClaude Opus 5 911ead5fbd docs(decisions-log): end-of-session PM handoff — six PRs open, and what a new machine needs
gate / gate (pull_request) Successful in 1m33s
gate / conformance (pull_request) Has been skipped
Written for a different session on a different computer. Lists the three open gated
PRs with their risk, the one command that must follow #11 (the drift detector skips
until its token exists, and a skipped detector detects nothing), and the three
credentials that are deliberately NOT in git and without which the toolbox and
cluster are unreachable: the age private key, prod.kubeconfig, and a Gitea
credential.

Records the measured platform state while telling the reader to re-measure it rather
than trust this log -- which is the whole point of CLAUDE.md section 2b, and which
this log earned by being confidently wrong for a month.

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.

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.**
## 2026-09-29 (end of session) — **PM HANDOFF.** Six PRs open; read this before touching anything.
The session that began "set a SOPS secret" ended having rebuilt the delivery pipeline. Plex is
claimed and scanning. `main` is genuinely protected and the gate genuinely enforces. What is
open is listed below with the reason each is not merged.
### MERGE THESE — both gated green
| PR | What | Risk |
|---|---|---|
| #12 | `CLUSTER_AVAILABLE=true` would have FAKED A GREEN over 54 skipped tests — now blocks | low; makes a wrong state loud |
| #13 | Admission boundary constraining the conformance CI trigger (R-SEC-02) + a fail-open fix in `ci/l0.sh` | medium; touches Kyverno + adds a Flux Kustomization |
(#11, the Gitea drift detector, was merged during this session — hence the action below.)
Order does not matter for correctness; if a later one conflicts, rebase and the gate re-runs
(~1m35s in CI, 76s local). **Each was gated in the pinned toolbox, not on a host.**
### DO THIS FIRST — #11 is merged and its detector is currently INERT
`ci/gitea-settings.sh` SKIPS until its token exists, and **a skipped detector detects nothing**:
./infra/gitea/set-ci-token.sh # mints + stores GITEA_SETTINGS_TOKEN, never prints it
Then open any PR and confirm the gate prints `gitea-settings: green`. ONLY THEN uncomment
`REQUIRE_GITEA_SETTINGS: "true"` in `.gitea/workflows/gate.yml`, so a future missing token blocks
instead of skipping. Doing that before seeing it green locks the repo.
Until then every gate run ends `MERGE GATE: UNDETERMINED` (exit 3) naming `gitea-settings` as
unrun. That is BY DESIGN and `gate.yml` tolerates exit 3, so PRs still pass — but it is not a
green run, and it is saying so honestly. The token is what turns it green.
### A DIFFERENT COMPUTER NEEDS THREE THINGS THAT ARE NOT IN GIT
This is the part that will silently waste an hour otherwise. None of these are in the repo, by
design, and without them the toolbox and the cluster are unreachable:
1. **`~/.config/sops/age/keys.txt`** — the age PRIVATE key. Without it NO `*.sops.yaml` can be
read or edited, and `sops` will fail in a way that looks like a broken file. Copy it from this
workstation; the public recipient in `.sops.yaml` is only half the pair.
2. **`infra/ansible/.cache/prod.kubeconfig`** — untracked, so it exists only in the main checkout
on this machine. Without it `dev.sh` refuses to start. In a git WORKTREE it is absent even
here: use `DEV_KUBECONFIG=/dev/null` for anything that needs no cluster (see `CLAUDE.md` §3).
3. **A Gitea credential** for `gitea.home.keithjackson.dev` (this session used the stored
`~/.git-credentials`). `git push` and every `infra/gitea/*.sh` script needs it.
### STATE, MEASURED — do not re-derive it from this log, re-measure it
`CLAUDE.md` §2b exists because this log was confidently wrong for a month. Verify before relying:
protected:true user_can_push:false enable_status_check:true
status_check_contexts:["gate / gate (pull_request)"] required_approvals:1
block_admin_merge_override:true runner incluster-dind: online gate ~1m35s
### NEXT WORK, in priority order
1. **Finish the L2/L3 wiring** now that the credential model is decided and #13 lands the
boundary. Still missing (`docs/plans/l2-l3-conformance-ci-wiring.md` §3): a runner image with
bash/python3/kubectl/git/chainsaw, an init-container cloning the repo at the PR SHA, results
collection via a base64 tar on stdout, and the `ci/conformance.sh` rewrite to drive the Job.
**Tighten the admission policy's image pattern to the literal digest when that image exists.**
2. **Do NOT set `vars.CLUSTER_AVAILABLE=true`** until step 1 is done. It does not enable L2/L3; it
only changes which way the stage fails (see #12).
3. The `gitea-settings` detector covers branch protection + runners. It does NOT yet cover Gitea
Actions **variables and secrets** — the next-nearest invisible surface.
4. `required_approvals: 1` with two accounts means a PR authored by `jakman85` needs `gitea-admin`
to approve. The operator holds ultimate authority and does not require that review; revisit if
it becomes friction.
### THE LESSON, because it caused every finding here
Four times this session the repository was treated as evidence about the live platform, and four
times it was wrong: the push that would "be rejected" (it would not have been), the token that
"could not survive the pipeline" (~2m45s, it fits), the required check that would "deadlock" (a
skipped Gitea job reports SUCCESS), and enforcement that was "on" (admins overrode it). Two
fail-opens in the gate itself were found the same way — `kyverno test` certifying policies that do
not load, and `CLUSTER_AVAILABLE` certifying 54 skipped tests as passed.
**Measure, then assert. `CLAUDE.md` §2b is the rule; this entry is the evidence for it.**
## 2026-09-29 (addendum, unattended) — the detector is armed; **I CANNOT MERGE, and that is correct**
Operator ran `set-ci-token.sh`, uncommented `REQUIRE_GITEA_SETTINGS` locally on `main`, and left
instructions to continue unattended and merge on green CI. Two things came out of that.
### 1. The detector was INERT, and would have stayed inert silently
`set-ci-token.sh` PUT the secret as `GITEA_SETTINGS_TOKEN`. **Gitea reserves the `GITEA_`
prefix** for secret names (as GitHub reserves `GITHUB_`) and rejected it:
HTTP 400 {"message":"invalid secret name"}
The script sent that PUT to `/dev/null` and printed `==> stored.` unconditionally; `curl -sS`
exits 0 on an HTTP error. **A token existed; no secret did.** So `ci/gitea-settings.sh` would
have skipped on every run forever — and enabling `REQUIRE_GITEA_SETTINGS` on top of that would
have BLOCKED EVERY PR, including the one fixing it. That is the exact lock-out this repo has now
nearly walked into three times.
Fixed in **PR #15**: the secret is `SETTINGS_API_TOKEN`, and `set-ci-token.sh` now checks the HTTP
status AND reads the secret back before claiming success. The missing verification was the real
defect; the illegal name is only what it hid. The secret is stored and verified present, and
**PR #15's CI is GREEN with `REQUIRE_GITEA_SETTINGS=true`** — which is the only proof that
matters, because a skip would have made it red.
The operator's local edit could not be pushed to `main` (protected). It is carried in PR #15.
### 2. No agent-authored PR can be merged without the operator — by design
Merging PR #12 as `gitea-admin` returned:
HTTP 405 {"message":"Does not have enough approvals"}
`required_approvals: 1` + `block_admin_merge_override: true` + two accounts, one of which
(`gitea-admin`) authors every agent PR and cannot self-approve. **So "merge on green CI" is not
something an agent can execute here.** That is the control working, not a fault — and it was
deliberately not circumvented. Self-approving would hollow out the boundary that was just built
and verified.
**This is an operator decision, not a bug to fix:** either accept that every agent PR waits for a
human approval (the honest reading of the control), or add a second human reviewer account, or
lower `required_approvals` to 0 and rely on the status check — which is the gate that actually
verifies something. Whichever, change the DECLARATION in
`infra/gitea/expected-branch-protection.json` in the same commit, or `gitea-settings` will
correctly fail the gate on the drift.
### Open PRs, all gated green, none mergeable by an agent
| PR | What |
|---|---|
| #12 | `CLUSTER_AVAILABLE=true` would have faked a green over 54 skipped tests — now blocks |
| #13 | Conformance-trigger admission boundary (R-SEC-02) + `kyverno test` fail-open fix |
| #14 | This handoff |
| #15 | Secret-name fix + `REQUIRE_GITEA_SETTINGS` enabled — **CI green with REQUIRE active** |
Suggested order: #15 first (it arms the detector and its CI already proved it), then #12, #13,
#14. If a later one conflicts, rebase; the gate re-runs in ~1m36s.
### Deliberately NOT done while unattended
No new feature work was started. Five unmerged PRs already stack review burden, and building the
next L2/L3 piece on top of unmerged branches would create a rebase tangle for no gain — the work
cannot land any faster. The next piece is specified and ready to start once these are merged:
`docs/plans/l2-l3-conformance-ci-wiring.md` §3, with §4's credential model now decided and its
boundary landed in #13.

# ci/gitea-settings.sh — Stage: the Gitea platform settings that gate this repo still
# match what git declares.
#
# WHY THIS STAGE EXISTS AT ALL
# ----------------------------
# Every other check in this repo reads the repository, the rendered manifests, or the
# cluster. NONE of them can see Gitea's own database — and that is where branch
# protection and runner registration live. On 2026-09-29 that blind spot was measured:
#
# * `main` had NO branch protection, and
# * ZERO Actions runners were registered,
#
# for roughly a month, while DECISIONS-LOG.md recorded both as working and every agent
# and human in the loop repeated that claim because the repository said so. PR #1 — the
# first pull request this repo ever had — sat `pending` for 30.6 minutes with nothing to
# execute it. Later the same day `enable_status_check` and `required_approvals` were turned
# on and STILL did not bite, because `block_admin_merge_override` was false; PRs #5-#9
# merged with zero approvals recorded against `required_approvals: 1`.
#
# Three separate failures, one shape: a setting that READ as enforced while not being, with
# no mechanism anywhere that could notice. Scripts that ASSERT the desired state
# (infra/gitea/*.sh) do not detect drift from it. This stage is the detector.
#
# WHAT IT ASSERTS
# 1. every key in infra/gitea/expected-branch-protection.json `.protection` matches the
# LIVE rule at /repos/{repo}/branch_protections/{branch}, exactly;
# 2. at least `.runners_online_min` Actions runners report status "online".
#
# (2) is not decoration. A required status check with no runner is the deadlock this repo
# nearly walked into: every PR pends forever, including the one that would fix it.
#
# READ THE RULE OBJECT, NOT THE BRANCH VIEW. /repos/{repo}/branches/{branch} reports
# `protected`, `enable_status_check` and `required_approvals` but NOT
# `block_admin_merge_override` — it showed all-green while the rule was overridable by the
# only account that merges. This stage queries /branch_protections/ deliberately.
#
# EXIT CODES (the gate contract)
# 0 live Gitea matches the declaration
# 1 DIVERGENCE — something drifted, or was never applied. Blocks the merge.
# 3 SKIP — no token, or Gitea unreachable. Never a pass; see gate.sh, which treats this
# skip like spec-immutability's (UNDETERMINED, exit 3) rather than a hard block, so
# that an unwired credential cannot lock the repository.
#
# TO WIRE IT: create a Gitea repo secret GITEA_SETTINGS_TOKEN (a token that can read repo
# settings) — infra/gitea/set-ci-token.sh does it. Until then this stage skips LOUDLY and
# the drift it exists to catch is still undetected.

# THE TRIGGER IDENTITY — deliberately NOT conformance-runner.
#
# THE ESCALATION THIS EXISTS TO CLOSE (docs/plans/l2-l3-conformance-ci-wiring.md §4):
# Kubernetes places NO `use` check on a Pod/Job's `serviceAccountName`. So any principal
# that can `create jobs` in this namespace can create a Job with
# `serviceAccountName: conformance-runner` and an ARBITRARY command — i.e. run arbitrary
# code with the runner's privileges (nodes/patch, pods/exec, namespaces/patch, jobs).
# A CI-held token with plain `create jobs` therefore IS the privileged identity, no matter
# how narrow its own RBAC looks. That would break R-SEC-02 ("CI holds no broad cluster
# access") while appearing to satisfy it.
#
# RBAC ALONE CANNOT FIX THIS. The real boundary is the admission policy
# platform/kyverno/admission/conformance-trigger-job-shape.yaml, which admits Jobs from
# THIS ServiceAccount only when they match the committed conformance shape. This Role is
# the necessary half; that policy is the sufficient half. Neither works alone — do not
# grant this Role without that policy reconciled and ENFORCING.

### `expected-branch-protection.json` + `ci/gitea-settings.sh` — the detector
`expected-branch-protection.json` **declares** the desired rule. `ci/gitea-settings.sh` runs as
a merge-gate stage, reads the LIVE rule, and **fails the gate on any divergence** — plus asserts
at least one runner is online. It is the only thing in this repository that can see Gitea's own
database.
It reads `/branch_protections/main`, not `/branches/main`: the branch view does **not** expose
`block_admin_merge_override`, and it showed all-green for hours while the rule was overridable.
Behaviour, proven by test rather than assumed:
| Situation | Exit | Effect |
|---|---|---|
| live matches the declaration | 0 | green |
| any key drifted, or no runner online | 1 | **blocks the merge** |
| no `GITEA_SETTINGS_TOKEN`, or Gitea unreachable | 3 | skips **loudly**; never a pass, never a block |
The skip is deliberately *not* a block: an unwired credential blocking every PR is the
lock-yourself-out failure this repo keeps hitting. Wire the token with `set-ci-token.sh`, confirm
the stage goes **green on a real PR**, and only then set `REQUIRE_GITEA_SETTINGS=true` in
`gate.yml` so a future missing token blocks instead of skipping.
**Changing the declaration is how you change policy.** If the live state is what you now want,
edit this JSON in the same commit — deliberately, in review — rather than letting the two drift.

# Kubernetes places NO `use` check on a Pod/Job's `serviceAccountName`. Any principal that can
# `create jobs` in namespace `conformance` can therefore create a Job that runs as
# `conformance-runner` — a privileged SA (nodes/patch, pods/exec, namespaces/patch) — with an
# arbitrary command. So the CI trigger credential, however narrow its own Role looks, IS the
# privileged identity unless something constrains the SHAPE of what it may create.
#
# That is what this does: for Jobs created by `conformance-trigger` ONLY, admit exactly the
# committed conformance run and deny everything else. The operator chose this model
# (docs/plans/l2-l3-conformance-ci-wiring.md §4, primary model) over the zero-credential

# ${KYVERNO_VALIDATION_ACTION} like the other admission policies: a security boundary that an
# environment overlay can downgrade to Audit is not a boundary. `failurePolicy: Fail` means a
# Kyverno outage blocks conformance Jobs rather than silently admitting unconstrained ones.
# Blocking CI is the correct failure direction here; admitting arbitrary privileged code is not.
