fix(ci)(interim): disable status-reaper + main-red-watchdog crons
RFC#420 Option-C machinery has been down ~2.5h: - status-reaper rev2 (PR#633, merged 01:48Z): 0 'Compensated by status-reaper' status on the last 14 main commits. Schedule reds stranded on stale commits despite the rev2 sweep-last-10 design. - main-red-watchdog: 'Failing after 10m56s' with timeout-minutes:5 — runner saturation queue-lag pushed it past its own timeout. No [main-red] issues filed during the outage despite 5 reds on HEAD e7965a0f at the high watermark. Both workflows were themselves contributing to the red pileup on main + queuing the ubuntu-latest pool. Cheap-and-safe interim: comment out the schedule: blocks. workflow_dispatch: stays so they can be triggered manually for debugging. Re-enable after: 1. rev3 lands (likely scan_workflows() should LOG-and-skip rather than sys.exit on a malformed workflow; list_recent_commit_shas() should degrade gracefully) 2. Dedicated status-ops runner-label (route status-reaper + watchdog + ci-required-drift to it so they don't queue behind CI-merge-churn) Per hongming-pc2 02:31Z directive: 'pick one: rev3+raise-timeout OR temporarily disable the crons'. Choosing disable for safety while rev3 investigation proceeds.

+"""ci-required-drift — RFC internal#219 §4 + §6.
+
+Detects drift between three sources of "what counts as a required check"
+for this repo, files (or updates) a `[ci-drift]` Gitea issue when any
+pair diverges.
+
+Sources:
+  A. `.gitea/workflows/ci.yml` jobs  (CI source — the actual job set)
+  B. `status_check_contexts` in branch_protections (the merge gate)
+  C. `REQUIRED_CHECKS` env in audit-force-merge.yml (the audit env)
+
+Three failure classes:
+  F1  Job in (A) is not under the sentinel's `needs:` — sentinel
+      doesn't gate it, so a red job on that name can sneak through.
+      Ignores jobs whose `if:` references `github.event_name` (those
+      run only on specific events and may be `skipped` legitimately).
+  F2  Context in (B) corresponds to no emitter — i.e. there's no job
+      in ci.yml whose runtime status-name maps to that context.
+      A stale required-check name is silent: protection demands a
+      green it never receives, but Gitea treats absent-as-pending,
+      not absent-as-red. The gate degrades to advisory.
+  F3  (B) and (C) are not set-equal. Audit env wider than protection
+      → audit flags non-force-merges as force; narrower → real
+      force-merges are missed.
+
+Idempotency:
+  Searches OPEN issues by exact title prefix
+  `[ci-drift] {repo}/{branch}: ` and either edits the existing one
+  (if any) or POSTs a new one. Never spawns duplicates.
+
+Behavior-based AST gate per `feedback_behavior_based_ast_gates`:
+  - Job set comes from PyYAML parse of jobs:* keys
+  - Sentinel needs from PyYAML parse of jobs[sentinel].needs (a list)
+  - Audit env from PyYAML parse, NOT grep — so reformatting the YAML
+    (block-scalar `|` vs flow-style list) does not break the gate

+"""main-red-watchdog — Option C of the "main NEVER goes red" directive.
+
+Tracking: molecule-core#420.
+
+What it does (one cron tick):
+  1. GET /api/v1/repos/{owner}/{repo}/branches/{watch_branch}
+     → current HEAD SHA on the watched branch.
+  2. GET /api/v1/repos/{owner}/{repo}/commits/{SHA}/status
+     → combined status + per-context statuses.
+  3. If combined state is `failure` (or any individual status is
+     `failure`): open or PATCH an idempotent
+     `[main-red] {repo}: {SHA[:10]}` issue. Body lists each failed
+     status context with `target_url` + `description`.
+  4. If combined state is `success`: close any open `[main-red]
+     {repo}: ...` issue on a previous SHA with a
+     "main returned to green at SHA {current_SHA}" comment.
+  5. Emit one Loki-shaped JSON line via `logger -t main-red-watchdog`
+     so `reference_obs_stack_phase1`'s Vector → Loki path ingests an
+     alert event (queryable in Grafana as
+     `{tenant="operator-host"} |~ "main-red-watchdog"`).
+
+What it does NOT do:
+  - Auto-revert anything. Option B is explicitly rejected per
+    `feedback_no_such_thing_as_flakes` + `feedback_fix_root_not_symptom`.
+  - Page on its own failures. If api() raises ApiError (transient
+    Gitea outage), the workflow run fails LOUDLY by re-raise — exactly
+    the contract `feedback_api_helper_must_raise_not_return_dict`
+    enforces. Silent fallthrough would re-introduce the duplicate-issue
+    regression class.
+  - Exit non-zero on RED. The issue IS the alarm; failing the watchdog
+    on red would double-page (red workflow + open issue) and create
+    silent-loop risk if the watchdog itself flakes.
+
+Idempotency strategy:
+  Title is keyed on `{SHA[:10]}` (commit-scoped), NOT just `main`.
+  Rationale:
+    - A fix-forward changes HEAD → next cron tick sees a new SHA;
+      auto-close logic closes the prior `[main-red] OLD_SHA` issue and
+      (if the new HEAD is also red, e.g. a different test fails) files
+      a fresh `[main-red] NEW_SHA`. Lineage is preserved.
+    - A revert that happens to land back on a previously-red SHA
+      (rare) would refer to a CLOSED issue; the watchdog never reopens.
+      That's a deliberate trade-off — the operator will see the latest
+      open issue's `closed` event in the activity feed.
+
+This module is import-safe: tests import individual functions without
+invoking main(), so module-level reads use env-with-default and the
+runtime contract enforcement lives in `_require_runtime_env()`.

+# 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 (=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 (Phase 1+2 evidence: rev1 saw
+     `compensated:0` every tick across ~6 cycles).
+
+  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`).

+#
+# 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.
+#

+#
+#   /qa-recheck   — re-evaluate the gate (e.g. after an APPROVE lands)

+
+# Ported from .github/workflows/railway-pin-audit.yml on 2026-05-11 per
+# RFC internal#219 §1 sweep.
+#
+# Differences from the GitHub version:
+#   - Dropped `workflow_dispatch:` (Gitea 1.22.6 trigger handling).
+#     Manual runs go via cron-trigger bump or push the workflow file
+#     itself.
+#   - `actions/github-script@v9` blocks (which call github.rest.* — a
+#     GitHub-specific JS API) replaced with curl calls against the
+#     Gitea REST API (/api/v1/repos/.../issues, .../labels,
+#     .../comments). Same behaviour: open issue on drift, comment on
+#     repeat-drift, close on clean run.
+#   - Workflow-level env.GITHUB_SERVER_URL set so the curl calls can
+#     derive `git.moleculesai.app` from the runner env (with
+#     hard-coded fallback inside the steps).
+#   - `continue-on-error: true` on the job (RFC §1 contract).
+#
+# Daily audit of Railway env vars for drift-prone image-tag pins —
+# automation-cadence layer over the detection script + regression test
+# shipped in PR #2168 (#2001 closure).
+#
+# Background: on 2026-04-24 a stale `:staging-a14cf86` SHA pin in CP's
+# TENANT_IMAGE caused 3+ hours of E2E failure with the appearance that
+# "every fix didn't propagate" — really the tenant image was so old it
+# didn't read the env vars those fixes produced.
+#
+# Cadence: once a day, 13:00 UTC (06:00 PT).
+#
+# Secret hardening: per feedback_schedule_vs_dispatch_secrets_hardening,
+# the schedule trigger HARD-FAILS on missing RAILWAY_AUDIT_TOKEN.

+
+# Ported from .github/workflows/runtime-prbuild-compat.yml on 2026-05-11
+# per RFC internal#219 §1 sweep.
+#
+# Differences from the GitHub version:
+#   - Dropped `merge_group:` (no Gitea merge queue) and `workflow_dispatch:`
+#     (Gitea 1.22.6 parser-rejects workflow_dispatch with inputs and is
+#     finicky without them).
+#   - `dorny/paths-filter@v4` replaced with inline `git diff` (per PR#372
+#     pattern for ci.yml port).
+#   - on.paths references .gitea/workflows/runtime-prbuild-compat.yml.
+#   - Workflow-level env.GITHUB_SERVER_URL set.
+#   - `continue-on-error: true` on every job (RFC §1 contract).
+#
+# Companion to `runtime-pin-compat.yml`. That workflow tests what's
+# CURRENTLY PUBLISHED on PyPI; this workflow tests what WOULD BE
+# PUBLISHED if THIS PR merges.
+#
+# Why two workflows: the chicken-and-egg #128 fix added a "PR-built
+# wheel" job to the original runtime-pin-compat.yml, but both jobs
+# shared a `paths:` filter that was the union of their needs
+# (`workspace/**`). That meant the PyPI-latest job ran on every doc
+# edit even though the upstream PyPI artifact can't change with our
+# workspace/ source. Splitting the two means each gets a narrow
+# `paths:` filter that matches the inputs it actually depends on.
+#
+# Catches the failure mode where a PR adds an import requiring a newer
+# SDK than `workspace/requirements.txt` pins:
+#   1. Pip resolves the existing PyPI wheel + the old SDK pin -> smoke
+#      passes (it imports the OLD main.py from the wheel, not the PR's
+#      new main.py).
+#   2. Merge -> publish-runtime.yml ships a wheel WITH the new import.
+#   3. Tenant images redeploy -> all crash on first boot with ImportError.

+# workflow's review-event subscription is silently dead. The result:

+#    Without this gate, a drive-by commenter on a public-issue-tracker

+# 3. Comment body must contain `/refire-tier-check` — a slash-command-

+# 4. This workflow does NOT check out PR HEAD code. Like sop-tier-check,
+#    it only HTTP-calls the Gitea API. Trust boundary preserved.
+#
+# Note: `issue_comment` fires from the BASE branch's workflow file. There
+# is no `pull_request_target` equivalent to set; the trigger inherently
+# loads the workflow from the default branch.

+# Tracking: molecule-core#? (this PR), internal#327 (sibling publish-runtime-bot),
+# internal#328 (sibling mc-drift-bot), internal#80 (upstream RFC). Sister
+# bots already deployed under the same per-persona-identity contract
+# (`feedback_per_agent_gitea_identity_default`).
+#
+# Root cause:
+#   Gitea 1.22.6 emits commit-status context as
+#     `<workflow_name> / <job_name> (push)`
+#   for ANY workflow run on the default branch's HEAD commit, REGARDLESS
+#   of the trigger event. Schedule- and workflow_dispatch-triggered runs
+#   on `main` therefore appear as `(push)` failures on the latest main
+#   commit, painting main red via a fake-push status. Verified on runs
+#   14525 + 14526 via Phase 1 evidence (3 sub-agents). No upstream fix
+#   in 1.23-1.26.1 (sibling a6f20db1 research).
+#
+# Why a cron-driven reaper, not workflow_run:
+#   Gitea 1.22.6 does NOT support `on: workflow_run` (verified via
+#   modules/actions/workflows.go enumeration; sister a6f20db1). The
+#   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)

+ *
+ * Coverage:
+ *   - Renders nothing when info=null
+ *   - Opens dialog when info is provided
+ *   - Default tab: "Universal MCP" when universal_mcp_snippet present, else "Python SDK"
+ *   - Tab switching between all available tabs
+ *   - Snippets show with auth_token replacing placeholders
+ *   - Copy button: calls clipboard API, shows "Copied!", clears after 1.5s
+ *   - Copy failure: shows fallback textarea
+ *   - "I've saved it — close" calls onClose
+ *   - Security warning: one-time token display
+ *   - Fields tab shows raw values
+ *   - Tabs hidden when their snippet is absent
+ *
+ * Fake timers: applied per-describe to avoid mixing with waitFor. Tests that
+ * use waitFor (which needs real timers) run without fake timers. Tests that
