Merge pull request 'fix(ci)(interim): disable status-reaper + main-red-watchdog crons (machinery-down)' (#645) from infra/interim-disable-reaper-watchdog-crons into main

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.

+"""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`).
+

+# status-reaper — Option B (compensating-status POST) for Gitea 1.22.6's
+# hardcoded `(push)` suffix on default-branch commit statuses.
+#
+# 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)
+# tracks the deletion as a follow-up sweep.

+"""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.

+# 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.
