+# review-check — evaluate whether a PR satisfies a single team-review gate.
+#
+# RFC#324 Step 1 of 5 — qa-review + security-review check workflows.
+#
+# This is the shared evaluator invoked by:
+#   .gitea/workflows/qa-review.yml      (TEAM=qa,      TEAM_ID=20)
+#   .gitea/workflows/security-review.yml (TEAM=security, TEAM_ID=21)
+#
+# Pass condition (per RFC#324 v1.1 addendum):
+#   ≥ 1 review on the PR where:
+#     • state == APPROVED
+#     • review.dismissed == false
+#     • review.user.login != PR.user.login (non-author)
+#     • review.user.login ∈ team-members
+#
+# Strict mode (default OFF for v1; see RFC trade-off note):
+#   If REVIEW_CHECK_STRICT=1, additionally require review.commit_id == PR.head.sha.
+#   With dismiss_stale_reviews: true at the protection layer, stale reviews
+#   are already dismissed, so the additional commit_id check is belt-and-
+#   suspenders. Keeping it off in v1 simplifies semantics; flip in a follow-up
+#   PR if reviewer telemetry shows residual stale-APPROVE merges.
+#
+# Privilege gate (RFC#324 v1.3 §A1.1 — INFORMATIONAL ONLY):
+#   The /qa-recheck and /security-recheck slash-commands can be triggered
+#   by anyone who can comment on the PR. The workflow's privilege step
+#   logs collaborator-status but does NOT gate execution of this script.
+#   Why this is safe: this evaluator is read-only and idempotent —
+#   reading `pulls/{N}/reviews` and `teams/{id}/members/{u}` can't be
+#   influenced by who triggered the run. If a real team-member APPROVE
+#   exists the gate flips green; otherwise it stays red. A
+#   non-collaborator commenting /qa-recheck cannot manufacture a green
+#   gate. Original (v1.2) design with `if:`-gating of this step was
+#   fail-open (skipped-via-`if:` job still publishes the status as
+#   `success`) — corrected in v1.3 per hongming-pc review 1421.
+#
+# Trust boundary (RFC A4):
+#   This script is loaded from the BASE branch (sourced via .gitea/scripts/
+#   on the workflow's checkout-of-base). It does NOT execute any PR-HEAD
+#   code. It only reads PR review state via the Gitea API.
+#
+# Token scope (RFC A1-α):
+#   The job's own conclusion (exit 0 / exit 1) is what publishes the
+#   `qa-review / approved` / `security-review / approved` status context.
+#   NO `POST /statuses` call here → NO `write:repository` scope on the
+#   token. `read:organization` (for team-membership probe) and
+#   `read:repository` (for PR + reviews) are enough.
+#
+# Required env:
+#   GITEA_TOKEN — least-priv read:repository + read:organization. See note
+#                 below about the team-membership API requiring the token
+#                 owner to be in the queried team (Gitea 1.22.6 quirk).
+#   GITEA_HOST  — e.g. git.moleculesai.app
+#   REPO        — owner/name (from github.repository)
+#   PR_NUMBER   — int (from github.event.pull_request.number or
+#                 github.event.issue.number for issue_comment events)
+#   TEAM        — short team name (qa | security) for log lines
+#   TEAM_ID     — Gitea team id (20=qa, 21=security at time of writing)

+"""status-reaper — Option B compensating-status POST for Gitea 1.22.6's
+hardcoded `(push)` suffix on default-branch commit statuses.
+
+Tracking: this PR (workflow + script + tests + audit issue). Sibling
+bots: internal#327 (publish-runtime-bot), internal#328 (mc-drift-bot).
+Upstream RFC: internal#80. Persona provisioned by sub-agent aefaac1b
+(2026-05-11 21:39Z; Gitea uid 94, scope=write:repository).
+
+What this script does, per `.gitea/workflows/status-reaper.yml` invocation:
+
+  1. Walk `.gitea/workflows/*.yml`. For each file, build the workflow_id
+     using this resolution (per hongming-pc 22:08Z review):
+       - If YAML has top-level `name:` → use that.
+       - Else → use filename stem (basename minus `.yml`).
+     Fail-LOUD on:
+       - Two workflows resolving to the SAME identifier (collision).
+       - Any identifier containing `/` (it would break context parsing
+         downstream — Gitea uses ` / ` as the workflow/job separator).
+     Classify each by whether `on:` contains a `push:` trigger.
+
+  2. List the last N (=30, rev3 — widened from 10) commits on
+     WATCH_BRANCH via GET /repos/{o}/{r}/commits?sha={branch}&limit={N}.
+     rev2 sweeps N commits per tick instead of HEAD only — schedule
+     workflows post `failure` to whatever SHA was HEAD when they
+     COMPLETED, so by the next */5 tick main has often moved forward
+     and the red gets stranded on a stale commit. rev3 widens the
+     window from 10 → 30 because schedule workflows post `failure`
+     RETROACTIVELY (5-15 min after their merge); a 10-commit window
+     is narrower than the merge-cadence during a burst, so reds land
+     OUTSIDE the window before reaper sees them (Phase 1+2 evidence:
+     rev2 run 17057 at 02:46Z saw 185/0 contexts on 10 SHAs; direct
+     probe ~30min later showed ~25 fails on those same 10 SHAs).
+
+  3. For EACH SHA in the list:
+       - GET combined commit status. Per-SHA error isolation
+         (refinement #7): if this call raises ApiError or any 5xx,
+         LOG `::warning::` + continue to the next SHA. Different from
+         the single-HEAD pre-rev2 path where fail-loud was correct;
+         the sweep is best-effort across historical commits, so one
+         transient blip on a stale SHA must not strand reds on the
+         OTHER stale SHAs.
+       - If combined.state == "success": skip — cost optimization
+         (refinement #2), common case (most commits are green).
+       - Otherwise iterate per-context entries. For each entry where:
+           state == "failure" AND context.endswith(" (push)")
+         Parse context as `<workflow_name> / <job_name> (push)`.
+         Look up workflow_name in the trigger map:
+           - missing → log ::notice:: and skip (conservative).
+           - has_push_trigger=True → preserve (real defect signal).
+           - has_push_trigger=False → POST a compensating
+             `state=success` status to /statuses/{sha} with the same
+             context (Gitea de-dups by context) and a description
+             documenting the workaround + this script's path.
+
+  4. Exit 0. Re-running is idempotent — Gitea's commit-status table
+     stores the LATEST state-per-context, so the success POST sticks
+     even if another tick happens before the runner finishes.
+
+What it does NOT do:
+  - Touch any context NOT ending in ` (push)`. The required-checks on
+    main (verified 2026-05-11) all have ` (pull_request)` suffixes;
+    they CANNOT be reached by this code path.
+  - Compensate `error`/`pending` states. Only `failure` — the only one
+    Gitea emits for the hardcoded-suffix bug.
+  - Write to non-default branches. WATCH_BRANCH is sourced from
+    `github.event.repository.default_branch` in the workflow.
+  - Mutate workflows or runs. The Actions UI still shows the
+    underlying schedule-triggered run as failed; this script edits
+    the commit-status surface only.
+
+Halt conditions (script-level — orchestrator-level halts are in the
+workflow comments):
+  - PyYAML missing → fail-loud at import (no fallback parse).
+  - Workflow `name:` collision → exit 1 with ::error:: message.
+  - Workflow `name:` containing `/` → exit 1 with ::error:: message.
+  - Ambiguous `on:` shape (e.g. neither str/list/dict) → treat as
+    "has_push_trigger=True" and log ::notice:: (preserve, never
+    compensate the unknown).
+  - api() non-2xx → raise ApiError, fail the workflow run loudly so
+    a subsequent tick retries (per
+    `feedback_api_helper_must_raise_not_return_dict`).

+# SHAs ~30min later. Root cause: schedule workflows post `failure`

+# qa-review — non-author APPROVE from the `qa` Gitea team required to merge.
+#
+# RFC#324 Step 1 of 5 (workflow-add). Pairs with `security-review.yml` and the
+# branch-protection flip in Step 2.
+#
+# === DESIGN (RFC#324 v1.1 addendum) ===
+#
+# A1-α (refire mechanism):
+#   Triggers on:
+#     - `pull_request_target`: opened, synchronize, reopened
+#         → initial status posts when PR opens / re-pushes
+#     - `issue_comment`: /qa-recheck slash-command on the PR
+#         → manual re-fire after a QA reviewer clicks APPROVE
+#           (Gitea 1.22.6 doesn't re-fire on pull_request_review, per
+#           go-gitea/gitea#33700 + feedback_pull_request_review_no_refire)
+#   Workflow name = `qa-review` ; job name = `approved`.
+#   The job's own pass/fail conclusion publishes the status context
+#   `qa-review / approved (<event>)` — NO `POST /statuses` call → NO
+#   write:repository token scope needed. Sidesteps internal#321 defect #2.
+#
+# A1.1 (privilege check on slash-comment — INFORMATIONAL ONLY, NOT a gate):
+#   The `issue_comment` event fires for ANY commenter, including
+#   non-collaborators. The original (v1.2) design gated the eval step
+#   behind a collaborator probe → if a non-collaborator commented
+#   /qa-recheck, the eval was `if:`-skipped → the job exited 0 anyway →
+#   the status context published `success` with ZERO real APPROVE.
+#   That was a fail-open: any visitor could green the gate.
+#
+#   RFC#324 v1.3 §A1.1 correction (option b per hongming-pc 1421):
+#   drop privilege-gating of the evaluation entirely. The eval is
+#   read-only and idempotent — it reads `pulls/{N}/reviews` and
+#   `teams/{id}/members/{u}` (both API-side state that a commenter can't
+#   change). Re-running it on a non-collaborator's comment is harmless
+#   AND correct: if a real team-member APPROVE exists, the eval flips
+#   green; if not, it stays red.
+#
+#   We KEEP the privilege step as a `::notice::` log line only — useful
+#   for griefer-spotting (one operator spamming /recheck) without
+#   touching the gate. If rate-limiting is needed later, add it as a
+#   separate concern (time-window throttle, not a privilege gate).
+#
+#   We MUST NOT use `github.event.comment.author_association` (the
+#   field doesn't exist on Gitea 1.22.6 webhook payload — this was
+#   sop-tier-refire's defect #1).
+#
+# A4 (no PR-head checkout under pull_request_target):
+#   We check out the BASE ref explicitly so the review-check.sh script is
+#   loaded from trusted source. We NEVER use `ref: ${{ github.event.pull_request.head.sha }}`.
+#   No PR-head code is executed in the runner. Trust boundary preserved.
+#
+# A5 (real Gitea team):
+#   `qa` team (id=20) verified by orchestrator preflight 2026-05-11; queried
+#   at run time via /api/v1/teams/20/members/{login}.
+#
+# === TOKEN ===
+#
+# The workflow reads PR state, PR reviews, and team membership.
+# Gitea 1.22.6's /api/v1/teams/{id}/members/{u} returns 403 ('Must be a
+# team member') for tokens whose owner is not in that team. The default
+# `secrets.GITHUB_TOKEN` is owned by a workflow-scoped identity that is
+# also not in qa/security teams → also 403.
+#
+# Resolution: a dedicated `RFC_324_TEAM_READ_TOKEN` secret, owned by an
+# identity that IS in both `qa` and `security` teams (Owners-tier
+# claude-ceo-assistant, or a new service-bot added to both teams).
+# Provisioning of this secret is tracked as a follow-up issue (filed by
+# core-devops at PR open).
+#
+# Until that secret is provisioned, the job will exit 1 with a clear
+# 403-on-team-probe error and the `qa-review / approved` status will
+# stay `failure`. This is the correct fail-closed behavior — the gate
+# blocks merge until both (a) a QA team member APPROVEs and (b) the
+# workflow has a token that can confirm their team membership.
+#
+# === SLASH-COMMAND CONTRACT ===
+#
+#   /qa-recheck   — re-evaluate the gate (e.g. after an APPROVE lands)
+#
+# Open to any PR commenter. The eval is read-only and idempotent, so
+# unprivileged refires are harmless (RFC#324 v1.3 §A1.1). Collaborator
+# status is logged for griefer-spotting but does NOT gate execution.

+#   only event-shaped option that fires is cron. 5min is chosen to
+#   sit BETWEEN ci-required-drift (`:17` hourly) and main-red-watchdog
+#   (`:05` hourly) so the reaper sweeps red before the watchdog files
+#   a `[main-red]` issue (would-be false-positive).
+#
+# What the reaper does each tick:
+#   1. Parse `.gitea/workflows/*.yml`, classify each by whether `on:`
+#      contains a `push:` trigger (see script for workflow_id resolution
+#      including `name:` collision and `/`-in-name fail-loud lints).
+#   2. GET combined status for main HEAD.
+#   3. For each `failure` status whose context ends ` (push)`:
+#      - if workflow has push trigger: PRESERVE (real defect signal).
+#      - if workflow has no push trigger: POST a compensating
+#        `state=success` with the same context and a description that
+#        documents the workaround.
+#
+# What it does NOT do:
+#   - Mutate non-`(push)`-suffix statuses (e.g. `(pull_request)` from
+#     branch_protections required-checks — verified safe 2026-05-11).
+#   - Auto-revert. Same reasoning as main-red-watchdog.
+#   - Cancel runs. The runs themselves stay visible in Actions UI; the
+#     fix is at the commit-status surface only.
+#
+# Removal path: drop this workflow when Gitea ≥ 1.24 ships with a
+# real fix for the hardcoded-suffix bug. Audit issue (filed post-merge)
+# tracks the deletion as a follow-up sweep.

+ * Tests for ScheduleTab — cron-based task scheduling.
+ *
+ * Coverage:
+ *   - Loading state
+ *   - Empty state (no schedules)
+ *   - Schedule list rendering (single + multiple)
+ *   - Status dot color (error/ok/idle)
+ *   - Toggle enable/disable via status dot
+ *   - Delete via ConfirmDialog
+ *   - Run Now button triggers POST + POST
+ *   - Create schedule form open/close
+ *   - Edit schedule form pre-fills values
+ *   - Form validation (disabled when cron/prompt empty)
+ *   - Create POST with correct payload
+ *   - Edit PATCH with correct payload
+ *   - Error state surfaces API failures
+ *   - Auto-refresh every 10s (spy)
+ *   - cronToHuman formatting
+ *   - relativeTime formatting
+ *   - Reset form clears all fields
+ *   - Disabled schedules are visually dimmed

+## Quirk #10 — Gitea does NOT auto-populate `secrets.GITHUB_TOKEN`
+
+### Finding
+
+Gitea Actions (1.22.6) does **not** auto-populate `secrets.GITHUB_TOKEN`
+the way GitHub Actions does. A workflow that references `secrets.GITHUB_TOKEN`
+without explicitly provisioning a named secret gets an empty string — not a
+read-only token scoped to the repo.
+
+### Impact
+
+Workflows that call the Gitea REST API using `secrets.GITHUB_TOKEN` as auth
+receive **HTTP 401** on every API call. Affected workflows in molecule-core:
+
+| Workflow | Symptom | Workaround |
+|---|---|---|
+| `gate-check-v3.yml` | Reports BLOCKED on every PR | Provision `SOP_TIER_CHECK_TOKEN`; update workflow to use it |
+| `qa-review.yml` | Fails immediately on PR open | Same — needs named secret |
+| `security-review.yml` | Fails immediately on PR open | Same — needs named secret |
+
+### How to diagnose
+
+Add a debug step to the failing workflow:
+
+```yaml
+- name: Diagnose token
+  run: |
+    echo "Token present: ${{ secrets.GITHUB_TOKEN != '' }}"
+    curl -sS --fail -H "Authorization: token ${{ secrets.GITHUB_TOKEN }}" \
+      "$GITHUB_SERVER_URL/api/v1/user" | jq -r '.login'
+    # Expected (GitHub): prints your username.
+    # Actual (Gitea): HTTP 401 or empty string.
+```

+
+## Quirk #11 — PR-create event dispatcher races — only 1 of N workflows fires on `pull_request opened`
+
+### Finding
+
+When a PR is created via the Gitea web UI or API, the Gitea Actions event
+dispatcher may fire **only 1 of N eligible workflows** on the initial
+`pull_request opened` event. All other eligible workflows are silently dropped.
+
+This was observed on molecule-core PR #558 (created 2026-05-11T19:54:10Z):
+12+ workflows had no `paths:` filter and should have fired, but only
+`sop-tier-check.yml` dispatched.
+
+Concurrent PRs created within the same minute received 12–30 dispatches each,
+confirming this is specific to the PR-create event dispatch, not a general
+runner capacity issue.
+
+### Impact
+
+- PRs may not run the full CI suite on first open.
+- `gate-check-v3`, `secret-scan`, `qa-review`, and `security-review` can be
+  silently absent from the PR's status checks.
+- Branch protection may block merge even though CI is effectively green.
+
+### How to diagnose
+
+```bash
+# List workflow runs for the PR:
+gh run list --event pull_request --repo molecule-ai/molecule-core \
+  | grep "$(gh pr view $PR --json number --jq '.number')"
+
+# Expected: 12+ runs on PR open.
+# Actual (when race fires): only 1 run.
+```
+
+### Workaround
+
+Force a second dispatch by pushing a no-op synchronize commit:
+
+```bash
+git commit --allow-empty -m "chore: trigger workflows [skip ci]"
+git push
+```
+
+The synchronize event fires a second `pull_request` event, which reliably
+triggers all eligible workflows.

+"""Tests for `.gitea/scripts/status-reaper.py` — Option B compensating
+status POST for Gitea 1.22.6's hardcoded `(push)` suffix bug.
+
+Coverage (per hongming-pc 22:08Z review + brief):
+  1. test_workflow_with_name_field
+  2. test_workflow_without_name_field (filename stem fallback)
+  3. test_workflow_name_collision_fails_loud
+  4. test_workflow_name_with_slash_fails_loud
+  5. test_has_push_trigger_true (dict shape, list shape, str shape)
+  6. test_has_push_trigger_false (schedule-only, dispatch-only,
+     pull_request-only, workflow_run-only)
+  7. test_publish_workspace_server_image_preserved (explicit case)
+  8. test_compensating_post_payload (POST body shape verification)
+
+Plus regression coverage:
+  - parse_push_context strictness (only ` (push)` suffix with ` / `
+    separator triggers compensation).
+  - Class-O detection via end-to-end reap() with a stubbed api().
+  - ApiError propagation on non-2xx (mirror of main-red-watchdog's
+    `feedback_api_helper_must_raise_not_return_dict` test).
+  - Unknown-workflow conservatism: ::notice:: + skip, never POST.
+  - Non-`(push)`-suffix contexts (the `(pull_request)` required-checks
+    on main) are NEVER touched — verified safe 2026-05-11.
+
+Hostile self-review proof:
+  - test_required_check_pull_request_suffix_never_touched exercises
+    the safety contract: a pre-fix that compensated any failing
+    context would mask the Secret scan required-check. Verified by
+    stashing the `endswith(PUSH_SUFFIX)` guard and re-running: test
+    FAILS as required.
+  - test_workflow_name_collision_fails_loud asserts exit code 1; a
+    pre-fix that "first write wins" would silently misclassify a
+    renamed workflow.

+// sqlmock CANNOT verify the actual partial-unique-index
+// behaviour. The unit tests in workspace_create_name_test.go pin
+// the helper's retry contract under a fake driver error, but only
+// a real Postgres can confirm:
+//
+//   - The migration 20260506000000 actually created the index.
+//   - lib/pq emits SQLSTATE 23505 with Constraint =
+//     "workspaces_parent_name_uniq" (not a synonym, not the message
+//     fallback).
+//   - The COALESCE(parent_id, sentinel) target collapses NULL
+//     parent_ids so two root-level workspaces with the same name
+//     collide as the migration intends.
+//   - The WHERE status != 'removed' partial filter exempts
+//     tombstoned rows from blocking re-use.
+//
+// Per feedback_mandatory_local_e2e_before_ship: ship-mode requires
+// the helper to be exercised against a real Postgres before the PR
+// merges.

+# Publish-runtime pipeline verification — 2026-05-11
+
+Marker file for the canonical end-to-end pipeline verification after
+`publish-runtime-bot` provisioning (internal#327) + stale-tag drift
+resolution (`runtime-v0.1.131` deleted from main).
+
+## Purpose
+
+Triggers `workspace/**` path filter on `publish-runtime-autobump.yml`,
+exercising the full pipeline:
+
+1. `publish-runtime-autobump / bump-and-tag` reads PyPI version, computes
+   next, pushes tag `runtime-v0.1.131` (or higher) using new bot scope.
+2. `publish-runtime.yml` fires on tag, builds + publishes to PyPI.
+3. Cascade autobump: 9 template repos get their `.runtime-version`
+   pinned to the new version.
+
+## Acceptance criteria
+
+- [ ] autobump bump-and-tag context green on merged commit
+- [ ] tag `runtime-v0.1.131` (or computed next) exists on molecule-core
+- [ ] publish-runtime.yml run green
+- [ ] PyPI molecule-ai-workspace-runtime updated from 0.1.130
+- [ ] 9 template repos updated their pinned runtime version
+
+## Rollback
+
+This file is informational only — no code dependency. Safe to delete
+in any future PR once pipeline is proven stable.
