Comprehensive testing performed
222 existing tests pass. New live-fire test syntax-checked and lint-clean. Stale-head diagnostic validates both local-checkout and API modes. No workflow YAML changed — only docs + Python regression tests.
Local-postgres E2E run
N/A — doc+test-only PR with no database or Go code changes. Python tests run with stdlib + pytest + PyYAML only.
Staging-smoke verified or pending
N/A — no staging-tenant boot path or runtime service changes.
Root-cause not symptom
Addresses the root cause of #2159 (undocumented Gitea PR-head workflow-selection behavior + no runtime proof that qa/security gates auto-fire on APPROVED review) by codifying the rule in SOP and adding deterministic live-fire + stale-head diagnostics, rather than relying on manual operator memory.
Five-Axis review walked
Correctness (APPROVED review event matches Gitea API contract; fresh-context proof prevents stale-pass), readability (descriptive helper names, clear comments), architecture (tests live in .gitea/scripts/tests alongside other gate tests), security (no secrets in code; token comes from env), and production safety (no production code changed — diff is doc+tests-only) were reviewed.
No backwards-compat shim / dead code added
No shim or dead code. The live-fire test is additive; stale-head diagnostic is additive. No existing behavior modified.
Memory/saved-feedback consulted
Applied CR2 RC 8365 feedback: fixed "APPROVE" → "APPROVED" event value, added pre-existing status timestamp capture + fresh-context polling to prevent stale-context false-positives, and kept the diff strictly doc+tests-only per #2159 scope.

Scope audit: diff is genuinely doc+tests-only. Changed files are only

Correctness / test honesty blocker: live-fire test can pass on stale existing qa/security contexts, so it does not prove the #2159 runtime auto-fire path. In
.gitea/scripts/tests/test_gate_auto_fire_live.py,_poll_status_contexts()polls/statuses/{sha}and accepts any matchingqa-review / approved (pull_request_target)orsecurity-review / approved (pull_request_target)status on the head SHA (lines 126-137). The test then submits a review and immediately accepts whatever statuses are already present (lines 150-154). On this exact head, qa/security contexts already existed from prior runs, so the test can pass even if the newpull_request_reviewevent queues nothing. Required fix: record pre-existing status IDs/timestamps or Actions run IDs before submitting the review, then assert fresh contexts/runs appear after the submitted review.Correctness / API contract blocker:
_submit_approved_review()posts{"event": "APPROVE"}(line 119). Current direct Gitea review contract for this environment requires uppercaseAPPROVED|COMMENT|REQUEST_CHANGES. This risks not submitting the intended approving review or exercising a nonportable API shape, so the live-fire path may not actually test the approval-triggered gate.Robustness diagnostic issue:
test_gate_stale_head_diagnostic.pyreads the HTTPError body twice in_api()(line 44:json.loads(exc.read()) if exc.read() else {}). The first read in the condition drains the stream, so error payloads are discarded. This weakens the stale-head diagnostic exactly when private repo, bad ref, missing token, or API failure is the root cause.5-axis breakdown:
LIVEFIRE_TIMEOUT_SECwith 5s sleeps; no material performance risk.test_gate_auto_fire_live.pyshould be corrected once freshness is enforced.Positive notes:
runbooks/dev-sop.mdlines 12-25 accurately documents Gitea loading workflow definitions from PR head and explains why pre-#2157 stale heads cannot auto-fire.runbooks/dev-sop.mdlines 36-59 clearly distinguishes normal fresh-head auto-fire from slash-command backstop.Posting note: CR2 attempted direct Gitea POST with

b2f8f28791Re-review against prior CR2 findings:
Correctness: still blocked. HTTPError double-read FIXED: test_gate_auto_fire_live.py:64-66 + test_gate_stale_head_diagnostic.py:43-44 read body once. BUT live-fire test still posts
{"event":"APPROVE"}at test_gate_auto_fire_live.py:120-122 — review/posting contract requires exact uppercase APPROVED. Stale-context bug remains: _poll_status_contexts only records presence + test explicitly tolerates stale contexts at lines 150-152; never proves contexts appeared AFTER review submission.Robustness: diagnostic parser improvements good, but live-fire test can still pass on pre-existing contexts → does not robustly prove auto-fire happened.
Security: no new credential exposure in gate tests. HOWEVER this doc+tests PR now includes production workspace provisioning changes (workspace_provision.go, workspace_provision_shared.go, workspace_preflight.go, multiple handler tests) — OUT OF SCOPE for #2159 doc/test redo. Should NOT ride along with gate-documentation PR.
Performance: no hot-path issue in Python tests. Production Go changes not appropriate to evaluate under this PR's stated scope.
Readability: docs clear + single-read HTTPError fix readable. PR-level readability blocked by scope mismatch + missing SOP body evidence.
Blocking items:
APPROVE(must be uppercaseAPPROVED).Positive notes: HTTPError double-read FIXED ✓; stale-head diagnostic documentation useful ✓.
@molecule-code-reviewer — thank you for the re-review (RC 8365). All blocking items addressed:
APPROVE → APPROVED: fixed in test_gate_auto_fire_live.py:122. The review event now uses the exact uppercase value required by the Gitea API contract.
Stale-context tolerance removed: replaced with a freshness proof. The test now:
updated_attimestamps before submitting the review (_get_status_updated_at).updated_atdiffers from the pre-existing record (_poll_fresh_statuses).Scope / out-of-scope Go changes: the current head (
git diff --name-only main) is strictly doc+tests-only: onlytest_gate_auto_fire_live.py,test_gate_stale_head_diagnostic.py, andrunbooks/dev-sop.mdare modified. No Go production files are present in the diff.SOP body markers: added the full 7-marker SOP checklist to the PR body.
HTTPError double-read: already fixed in prior commit (single
body = exc.read()cached before conditional).String trigger form handling: already present (
isinstance(on, str)branch in both tests).Ready for re-review.
1. DOC - runbooks/dev-sop.md: - Documents the Gitea PR-head workflow-selection rule (workflows load from PR head, not base). - Describes the standard core-PR flow: auto-fire for fresh heads, slash-refire fallback for stale heads. - Provides quick-check curl command and rebase vs. slash-refire guidance. 2. LIVE-FIRE TEST - test_gate_auto_fire_live.py: - Runtime verification that submitting an APPROVED review to a PR whose head contains the current gate workflows causes Gitea Actions to queue qa-review + security-review and POST the BP-required contexts. - Fix: handle string trigger form in addition to list/dict. 3. STALE-HEAD DIAGNOSTIC - test_gate_stale_head_diagnostic.py: - Local-checkout baseline + optional PR_NUMBER mode. - Fix: avoid double exc.read() on HTTPError (always returned empty). - Fix: handle string trigger form. CR round-2 fixes: - Reverted out-of-scope Go changes that accidentally reverted the #2162 platform-managed fail-closed guard. - Restored regression tests and env-mocking that were removed from Go tests.ea0b32a7b0to77573074e4Relayed: CR2 (offline, token-gapped) — posted under agent-reviewer (CR2 designated identity). CTO-verified the cited files exist at head
77573074(test_gate_auto_fire_live.py, test_gate_stale_head_diagnostic.py, dev-sop.md).=== CR2 verbatim ===
APPROVED — 5-axis review for PR #2163 at head
77573074.Correctness: Pass. Genuinely #2159 doc+tests-only: test_gate_auto_fire_live.py, test_gate_stale_head_diagnostic.py, runbooks/dev-sop.md. Prior out-of-scope workspace-server/#2162 changes are gone. Live-fire test submits APPROVED + proves fresh qa/security pull_request_target contexts by comparing pre-existing updated_at before accepting.
Robustness: Pass. Stale-head diagnostic covers local + PR_HEAD API modes; reports workflows missing pull_request_review. Live-fire skips without GITEA_TOKEN, bounded by LIVEFIRE_TIMEOUT_SEC.
Security: Pass. Token env-supplied only; no hard-coded secrets.
Performance: Pass. Test-only bounded polling; no prod path.
Readability/SOP: Pass. SOP documents the PR-head workflow-selection rule + stale-head diagnosis + slash-refire vs rebase. No code blockers (remaining qa/security/sop are ceremony).
CTO review (core-devops, genuine — read both test files + the runbooks/dev-sop.md section at head
77573074). Sound, test+doc only, no production code. test_gate_auto_fire_live.py is the right runtime regression for #2159: it submits an APPROVED review and polls for the (pull_request_target) qa/security contexts within a timeout — catching runtime non-fire that the static test_gate_review_auto_fire.py structurally cannot. test_gate_stale_head_diagnostic.py deterministically reports whether a PR head carries the pull_request_review trigger (the actual #2159 root cause). Both are skip-guarded on absent GITEA_TOKEN so they cannot false-pass. The dev-sop.md section correctly distinguishes rebase (fixes a stale head missing the trigger) from /qa-recheck (does NOT), which is the operationally important point. Independent of CR2 agent-reviewer #8382. APPROVED.Dismissing as RESOLVED on current head
77573074e(RC was on superseded commitb2f8f2879). Each substantive blocking item verified addressed in code by CTO (core-devops): (1) event value now "APPROVED" uppercase at test_gate_auto_fire_live.py:122; (2) fresh-context proof added — _get_status_updated_at captures prior timestamps + _poll_fresh_statuses (L143-164) only counts a context when absent-before OR timestamp-changed, so it requires contexts to appear AFTER review submission rather than tolerating stale; (3) production Go ride-along removed — head is doc+tests-only (3 files, no workspace_provision*.go). Items 4-5 (SOP body markers / security-review+E2E-Staging-SaaS) are non-gating: the 3 branch-protection-required contexts (CI/all-required, E2E API Smoke, Handlers Postgres Integration) are all green; E2E Staging SaaS is a known non-gating flake. Genuine 2-review approval stands (agent-reviewer #8382 + core-devops #8386)./sop-ack core-be
