Merge pull request 'fix(platform): install docker-cli in workspace-server image — unblocks RegistryModeLocal' (#765) from infra/dockerfile-add-docker-cli-for-local-build into main

JSON null unmarshals to []byte("null") (4 bytes), not nil, so
len(trace)==0 missed it. Empty array []byte("[]")==2 bytes was also
returned unchanged. Add explicit string checks for both cases.

Also fix TestExtractToolTrace_ValidNonEmpty: json.Marshal compacts
spacing, so byte-exact comparison against spaced literal fails on
round-trip. Use compact literal instead.

Fixes mc#669 (null tool_trace panic path).

+"""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

+"""lint-required-no-paths — structural enforcement of
+`feedback_path_filtered_workflow_cant_be_required`.
+
+For every workflow whose status-check context appears in
+`branch_protections/<branch>.status_check_contexts`, assert that the
+workflow's `on:` block has NO `paths:` and NO `paths-ignore:` filter.
+
+A required-check workflow with a paths filter silently degrades the
+merge gate:
+
+  - If the PR's diff doesn't match the `paths:` glob, the workflow
+    never fires.
+  - Gitea (1.22.6) reports the required context as `pending` (never as
+    `skipped == success`), so the PR cannot merge.
+  - For a docs-only PR against `paths: ['**.go']`, the PR is
+    blocked forever — no human action can produce a green.
+
+The class was previously prevented only by reviewer vigilance + the
+saved memory `feedback_path_filtered_workflow_cant_be_required`. This
+script makes it a hard CI gate so a future PR adding `paths:` to a
+required workflow fails fast at PR time, not after merge when the next
+docs PR wedges main.
+
+The lint runs as `.gitea/workflows/lint-required-no-paths.yml` on every
+PR. The lint workflow ITSELF must not have a paths-filter (otherwise it
+could be circumvented by a paths-non-matching PR) — that's enforced by
+self-reference and by the workflow's own `on:` block deliberately
+omitting filters.
+
+Sources of truth:
+  - `branch_protections/<branch>` `status_check_contexts` (the merge gate)
+  - `.gitea/workflows/*.yml` `name:` + `on:` (the workflow set)
+
+Context-format note (Gitea 1.22.6):
+  Status-check contexts are formatted `{workflow_name} / {job_name_or_key} ({event})`.
+  We parse the workflow_name prefix and walk `.gitea/workflows/*.yml` for
+  a file whose `name:` attr matches. (The filename is NOT the source of
+  truth; `name:` is, because Gitea formats the context from `name:`.)
+
+Exit codes:
+  0 — no required workflow has a paths/paths-ignore filter (clean) OR
+      branch_protections endpoint returned 403/404 (token-scope issue;
+      surfaced via ::error:: but non-fatal so a missing scope doesn't
+      red-X every PR — fix the token, not the lint).
+  1 — at least one required workflow has a paths/paths-ignore filter
+      (the gate-degrading defect class).
+  2 — env contract violation (missing GITEA_TOKEN/HOST/REPO/BRANCH).
+  3 — workflows directory missing or workflow YAML unparseable.
+  4 — protection response shape unexpected (non-dict body on 2xx).
+
+Auth note: `GET /repos/.../branch_protections/{branch}` requires
+repo-admin role in Gitea 1.22.6. The workflow-default `GITHUB_TOKEN`
+is non-admin; we re-use `DRIFT_BOT_TOKEN` (same persona that powers
+ci-required-drift.yml). If `DRIFT_BOT_TOKEN` is unavailable in a future

+"""lint-workflow-yaml — catch Gitea-1.22.6-hostile workflow YAML shapes.
+
+This script enforces six structural rules that have historically caused
+silent CI failures on Gitea Actions (1.22.6) — workflows that the server's
+YAML parser rejects with `[W] ignore invalid workflow ...` and registers
+for zero events, or shape conventions that produce ambiguous status
+contexts. Each rule maps to a documented incident in saved memory.
+
+Rules (4 fatal + 1 fatal cross-file + 1 heuristic-warn):
+  1. `workflow_dispatch.inputs:` block — Gitea 1.22.6 mis-parses the
+     `inputs` keys as sibling event types and rejects the whole file.
+     Memory: feedback_gitea_workflow_dispatch_inputs_unsupported.
+     Origin: 2026-05-11 PyPI freeze (publish-runtime).
+  2. `on: workflow_run:` event — not enumerated in Gitea 1.22.6's
+     supported event list (verified via modules/actions/workflows.go
+     enumeration; task #81). Workflow registers, fires for 0 events.
+  3. `name:` containing `/` — breaks the
+     `<workflow> / <job> (<event>)` commit-status context convention;
+     downstream parsers (sop-tier-check, status-reaper) tokenize on `/`.
+  4. `name:` collision across files — Gitea routes commit-status updates
+     by `name` and behavior on collision is undefined (status-reaper
+     rev1 fail-loud).
+  5. Cross-repo `uses: org/repo/path@ref` — blocked while
+     `[actions].DEFAULT_ACTIONS_URL=github` is the server default;
+     resolves to github.com/<org-suspended>/... and 404s.
+     Memory: feedback_gitea_cross_repo_uses_blocked. Cross-link: task #109.
+  6. (HEURISTIC, warn-not-fail) Steps reference `https://api.github.com`
+     or `https://github.com/.../releases/download` without a
+     workflow-level `env.GITHUB_SERVER_URL` set to the Gitea instance.
+     Memory: feedback_act_runner_github_server_url.
+
+Per `feedback_smoke_test_vendor_truth_not_shape_match`: fixtures used to
+validate this lint must mirror real Gitea 1.22.6 YAML semantics, not
+Python yaml-parser quirks. The test suite at tests/test_lint_workflow_yaml.py
+includes a vendor-truth fixture (the exact publish-runtime regression).
+
+Usage:
+  python3 .gitea/scripts/lint-workflow-yaml.py
+    Lint every `*.yml` in `.gitea/workflows/`.
+
+  python3 .gitea/scripts/lint-workflow-yaml.py --workflow-dir <path>
+    Lint a custom directory (used by tests/test_lint_workflow_yaml.py).
+
+Exit codes:
+  0 — clean OR only heuristic-warnings emitted.
+  1 — at least one fatal rule (1-5) violated.
+  2 — YAML parse error or argv usage error.

+"""lint_bp_context_emit_match — Tier 2f per internal#350.
+
+Rule
+----
+For a given protected branch, every context in
+`branch_protections/<branch>.status_check_contexts` MUST be emitted
+by at least one workflow in `.gitea/workflows/*.yml`. Two contexts
+match when:
+
+  1. The workflow's `name:` equals the context's workflow-part (the
+     prefix before ` / `).
+  2. Some job in that workflow has a `name:` (or default-fallback
+     job-key) equal to the context's job-part (between ` / ` and
+     ` (`).
+  3. The workflow's `on:` block includes the context's event-part
+     (in parens at the end), with Gitea's event-name mapping:
+        - `pull_request` and `pull_request_target` BOTH emit
+          `(pull_request)` contexts (verified empirically on
+          molecule-core/main).
+        - `push` emits `(push)`.
+
+A BP context with no emitter blocks merges forever — Gitea treats
+absent-as-`pending`, NOT absent-as-`skipped`-as-`success`. This is
+the phantom-required-check class
+(`feedback_phantom_required_check_after_gitea_migration`).
+
+The inverse direction (emitter without BP context) is INFORMATIONAL
+only — Tier 2g handles that direction at PR-time. Flagging it here
+on a daily schedule would falsely surface every transitional state
+during a BP rollout.
+
+How the gate works
+------------------
+Daily scheduled run + workflow_dispatch:
+
+  1. GET `branch_protections/{BRANCH}` (needs DRIFT_BOT_TOKEN with
+     repo-admin scope; same persona as ci-required-drift.yml).
+     Graceful-degrade on 403/404 per Tier 2a contract.
+
+  2. Walk `.gitea/workflows/*.yml` via PyYAML AST. For each workflow,
+     enumerate its emitted contexts: `{workflow.name} / {job.name or
+     job-key} ({event})` for each event in `on:` that emits a status.
+
+  3. For each BP context, look for an emitter match. Aggregate
+     orphans.
+
+  4. If orphans exist:
+     - File or PATCH a `[ci-bp-drift]` issue (idempotency contract:
+       search for exact title prefix, edit existing if open).
+     - Apply labels `tier:high` + `ci-bp-drift` (lookup IDs per
+       repo; per `feedback_tier_label_ids_are_per_repo`).
+     - Exit 1.
+
+  5. If no orphans:
+     - Close any existing `[ci-bp-drift]` issue with a clean-state
+       comment.
+     - Exit 0.
+
+Exit codes
+----------
+  0 — clean OR API 403/404 (graceful-degrade, surfaces ::error::).
+  1 — at least one BP context has no emitter.
+  2 — env contract violation, workflows-dir missing, or YAML parse
+      error.
+
+Env
+---
+  GITEA_TOKEN     — DRIFT_BOT_TOKEN (repo-admin for branch_protections)
+  GITEA_HOST      — e.g. git.moleculesai.app
+  REPO            — owner/name
+  BRANCH          — defaults to `main`
+  WORKFLOWS_DIR   — defaults to `.gitea/workflows`
+  DRIFT_LABEL     — defaults to `ci-bp-drift`

+"""lint_continue_on_error_tracking — Tier 2e per internal#350.
+
+Rule
+----
+Every `continue-on-error: true` directive in `.gitea/workflows/*.yml`
+must be accompanied by a tracker reference comment within 2 lines
+(above OR below the directive's line). The reference is one of:
+
+  * `# mc#NNNN`          — molecule-core issue
+  * `# internal#NNNN`    — molecule-ai/internal issue
+
+The referenced issue must satisfy ALL of:
+
+  1. Exists (HTTP 200 on `/repos/{owner}/{name}/issues/{num}`)
+  2. `state == "open"`
+  3. `created_at` is ≤ MAX_AGE_DAYS days ago (default 14)
+
+A passing reference establishes an audit trail and a forced renewal
+cadence — after 14 days the issue must either be CLOSED (the masked
+defect was fixed) or the comment must point at a NEW tracker
+(deliberate decision to keep masking, requires a paper-trail).
+
+The class this prevents
+-----------------------
+Phase-3-masked failures. `continue-on-error: true` on `platform-build`
+had been hiding mc#664-class regressions for ~3 weeks before #656
+surfaced them on 2026-05-12. A 14-day cap forces a tracker review
+cycle and surfaces mask-drift within at most 14 days of the original
+defect.
+
+Behaviour-based gate
+--------------------
+We parse via PyYAML AST (per `feedback_behavior_based_ast_gates`) to
+detect `continue-on-error: <truthy>` at job-key level, then map each
+location back to its source line via PyYAML's line-tracking loader.
+Comments are scanned from the raw text within a 2-line window of
+that source line. Reformatting (block-scalar vs flow-style) does not
+break the rule because the source-line anchor is the directive's
+own line.
+
+Exit codes
+----------
+  0 — every `continue-on-error: true` has a passing tracker, OR
+      the issue-API endpoint returned 403/404 (token-scope; graceful
+      degrade per Tier 2a contract — surface via ::error:: on stderr
+      but don't red-X every PR over auth).
+  1 — at least one violation (missing/closed/too-old/non-existent
+      tracker).
+  2 — env contract violation, YAML parse error, or workflows-dir
+      missing.
+
+Env
+---
+  GITEA_TOKEN     — read scope on the configured repos.
+                    Auto-injected `GITHUB_TOKEN` works for same-repo
+                    issue reads; for `internal#NNN` we need a token
+                    with `molecule-ai/internal` read scope. Use
+                    DRIFT_BOT_TOKEN (same persona as other Tier 2
+                    lints).
+  GITEA_HOST      — e.g. git.moleculesai.app
+  REPO            — `owner/name` for `mc#NNNN` lookups
+  INTERNAL_REPO   — `owner/name` for `internal#NNNN` lookups
+                    (defaults to derived `molecule-ai/internal`)
+  WORKFLOWS_DIR   — defaults to `.gitea/workflows`
+  MAX_AGE_DAYS    — defaults to 14

+"""lint_mask_pr_atomicity — Tier 2d structural enforcement per internal#350.
+
+Rule
+----
+A PR whose diff touches `.gitea/workflows/ci.yml` AND modifies EITHER:
+
+  - any `continue-on-error:` value, OR
+  - the `all-required` sentinel job's `needs:` block
+
+must EITHER:
+
+  - Touch BOTH atomically in the same PR (preferred), OR
+  - Cross-link the paired PR via a literal `Paired: #NNN` reference in
+    the PR body OR in any commit message between BASE_SHA and HEAD_SHA.
+
+The class this prevents
+-----------------------
+PR#665 (interim `continue-on-error: true` on `platform-build`) and
+PR#668 (sentinel-`needs` demotion of the same job) were designed as a
+pair but merged solo — #665 landed at 04:47Z 2026-05-12, #668 was still
+open at 05:07Z when the main-red watchdog (#674) fired. Result: ~20
+minutes of `main` red and a cascade of false-positives on unrelated PRs.
+
+The lint operates on the YAML AST (PyYAML), not grep, per
+`feedback_behavior_based_ast_gates`: a refactor that moves `continue-on-error`
+between job keys, or renames the `all-required` job, would still be
+detected because we walk the parsed structure.
+
+Why this works on Gitea 1.22.6
+------------------------------
+We don't use any 1.22.6-missing endpoints (no `/actions/runs/*`, no
+`branch_protections/*` — Tier 2f/g need those; Tier 2d does not). All
+required inputs come from the workflow `pull_request` event payload
+(BASE_SHA, HEAD_SHA, PR_BODY) and from local git via `git show`/`git log`.
+The auto-injected `GITHUB_TOKEN` is enough; we don't need
+DRIFT_BOT_TOKEN.
+
+Exit codes
+----------
+  0 — ci.yml not in diff, OR diff is no-op for the rule predicates,
+      OR atomicity satisfied (both touched), OR a valid `Paired: #NNN`
+      reference is present.
+  1 — exactly ONE of {coe, sentinel-needs} touched AND no valid
+      `Paired: #NNN` reference. The split-pair regression class.
+  2 — env contract violation (BASE_SHA / HEAD_SHA missing) or YAML
+      parse error on either side.
+
+Env
+---
+  BASE_SHA          — PR base (pull_request.base.sha)
+  HEAD_SHA          — PR head (pull_request.head.sha)
+  PR_BODY           — pull_request.body (may be empty)
+  CI_WORKFLOW_PATH  — defaults to `.gitea/workflows/ci.yml`
+  SENTINEL_JOB_KEY  — defaults to `all-required`
+
+Memory cross-links
+------------------
+  - internal#350 (the RFC that specs this lint)
+  - PR#665 / PR#668 (the empirical split-pair)
+  - mc#664 (the main-red incident)
+  - feedback_strict_root_only_after_class_a
+  - feedback_behavior_based_ast_gates

+"""lint-pre-flip-continue-on-error — block a PR that flips a job from
+``continue-on-error: true`` to ``continue-on-error: false`` (or removes
+the key while the base had it ``true``) without proof that the job's
+recent runs on the target branch are actually green.
+
+Empirical class — PR #656 / mc#664:
+  PR #656 (RFC internal#219 Phase 4) flipped 5 ``platform-build``-class
+  jobs ``continue-on-error: true → false`` on the basis of a
+  "verified green on main via combined-status check". But that "green"
+  was the LIE produced by the prior ``continue-on-error: true``:
+  Gitea Quirk #10 (internal#342 + dup #287) — when a step inside a
+  job marked ``continue-on-error: true`` fails, the job-level status
+  is still rolled up as ``success``. So the precondition the PR
+  claimed to verify was structurally fooled by the bug being
+  flipped.
+
+  mc#664 then captured the surfaced defects (2 unrelated, mutually-
+  masked regressions):
+
+    Class 1: sqlmock helper drift since 2f36bb9a (24 days old)
+    Class 2: OFFSEC-001 contract collision since 7d1a189f (1 day old)
+
+  Codified 04:35Z as hongming-pc2 charter §SOP-N rule (e)
+  "run-log-grep-before-flip": pull the actual run log + grep for
+  ``--- FAIL`` / ``FAIL\\s`` BEFORE flipping; don't trust the masked
+  combined-status.
+
+This script structurally enforces that rule at PR time.
+
+How it works (one PR tick):
+  1. Parse the diff: compare ``.gitea/workflows/*.yml`` at PR base
+     vs PR head. For each file present in both, parse the YAML AST
+     and walk ``jobs.<key>.continue-on-error`` on each side. A
+     "flip" is base ∈ {true} AND head ∈ {false, None/absent}. We
+     coerce truthy/falsy per YAML semantics (PyYAML normalizes
+     ``true``/``True``/``yes`` to ``True``).
+  2. For each flipped job, derive its commit-status context name as
+     ``"{workflow.name} / {job.name or job.key} (push)"`` — that's
+     how Gitea Actions emits the context for runs on
+     ``main``/``staging`` (push event, see also expected_context()
+     in ci-required-drift.py).
+  3. Pull the last N commits of the target branch (PR base), fetch
+     combined commit-status per commit, scan ``statuses[]`` for
+     contexts matching ANY of the flipped jobs. For each match,
+     fetch the actual run log via the web-UI route
+     ``{server_url}/{repo}/actions/runs/{run_id}/jobs/{job_idx}/logs``
+     (per memory ``reference_gitea_actions_log_fetch`` — Gitea 1.22.6
+     lacks REST ``/actions/runs/*`` endpoints; the web-UI route is the
+     only working path; see ``reference_gitea_1_22_6_lacks_rest_rerun_endpoints``).
+  4. Grep each log for the Go-test failure markers ``--- FAIL`` /
+     ``FAIL\\s+<package>`` AND the bash-step error sentinel
+     ``::error::``. If ANY recent log shows any of these AND the
+     status itself reads ``success``, the job was masked. ``::error::``
+     the flip with the offending test name + offending run URL +
+     the regression commit (HEAD of the run).
+  5. Exit 1 if any flips have at least one masked run; exit 0
+     otherwise.
+
+Halt-on-noise contract:
+  - If a recent log fetch 404s (already-pruned-via-act_runner-gc,
+     transient gitea-web outage): emit ``::warning::`` and treat the
+     run as "log unavailable" — does NOT block the flip; logged so
+     a curious reviewer can re-run.
+  - If a flipped job has ZERO recent runs on the target branch (newly
+     added workflow): emit ``::warning::`` "no run history to verify"
+     and allow the flip. This is the only way a NEW workflow can ever
+     ship with ``continue-on-error: false``; otherwise we'd have a
+     chicken-and-egg.
+
+Behavior-based AST gate per ``feedback_behavior_based_ast_gates``:
+  - YAML parsed via PyYAML safe_load on BOTH sides of the diff
+  - No grep-by-line — formatting changes (comment churn, key order)
+    don't false-positive a flip
+  - Job-key match — so a rename ``platform-build → core-be-build``
+    appears as a DELETE + an ADD, not a flip (the delete side has no
+    new value to compare against; the add side has no base side).
+
+Run locally (works against this repo, requires PyYAML + Gitea token
+that can read combined-commit-status):
+
+    GITEA_TOKEN=... GITEA_HOST=git.moleculesai.app \\
+      REPO=molecule-ai/molecule-core BASE_REF=main \\
+      BASE_SHA=$(git rev-parse origin/main) \\
+      HEAD_SHA=$(git rev-parse HEAD) \\
+      python3 .gitea/scripts/lint_pre_flip_continue_on_error.py \\

+"""lint_required_context_exists_in_bp — Tier 2g per internal#350.
+
+Rule
+----
+When a PR adds a NEW commit-status emission (a context that didn't
+exist on the base side), the workflow file must carry one of three
+directive comments adjacent to the new job:
+
+  (a) `# bp-required: yes`
+      The new context MUST already be in
+      `branch_protections/<branch>.status_check_contexts`. Verified
+      via Gitea API at PR time.
+
+  (b) `# bp-required: pending #NNN`
+      Acknowledged asymmetry; references an OPEN tracking issue that
+      will follow up with the BP PATCH.
+
+  (c) `# bp-exempt: <free-text reason>`
+      Informational job, not intended to be a required gate.
+
+No directive on a new emitter → FAIL with a 3-option fix-hint.
+
+The class this prevents
+-----------------------
+PR#656 added `CI / all-required (pull_request)` as a sentinel context
+that workflows emit, but BP did NOT list it. When `platform-build`
+failed, `all-required` failed, but BP let the PR merge anyway →
+cascade to mc#664. With this lint, PR#656 would have been blocked
+until either the BP PATCH ran alongside OR the author added a
+`bp-required: pending` directive.
+
+Why directives MUST live in the workflow YAML
+---------------------------------------------
+The directive comment lives with the emitter so a scheduled
+audit (Tier 2f, daily) can read the same source. PR-body-only
+directives invisibly evaporate on merge — the asymmetry would
+return to undetected. PR-body claims are advisory; workflow-file
+comments are the contract.
+
+How "new emission" is detected
+------------------------------
+Diff base..head over `.gitea/workflows/*.yml`. For each YAML file
+that's added or modified:
+  - Parse both base-side and head-side via PyYAML AST.
+  - Enumerate emitted contexts on each side using the same rules as
+    Tier 2f (workflow.name + job.name|key + event-mapping).
+  - `new_contexts = head_contexts - base_contexts`.
+
+If `new_contexts` is empty after de-dup, no rule applies → pass.
+
+Per `feedback_behavior_based_ast_gates`: comment scanning uses raw
+text in a small window around the job-key line, NOT regex over the
+full file. This avoids matching `bp-required:` mentioned in a
+comment unrelated to the new job.
+
+Exit codes
+----------
+  0 — no new emissions, all new emissions have valid directives,
+      or BP read errored (graceful-degrade per Tier 2a contract).
+  1 — at least one new emission lacks a directive, or has
+      `bp-required: yes` but the context is missing from BP.
+  2 — env contract violation or YAML parse error.
+
+Env
+---
+  BASE_SHA          — PR base SHA
+  HEAD_SHA          — PR head SHA
+  GITEA_TOKEN       — DRIFT_BOT_TOKEN (repo-admin for BP read)
+  GITEA_HOST        — e.g. git.moleculesai.app
+  REPO              — owner/name
+  BRANCH            — defaults to `main`
+  WORKFLOWS_DIR     — defaults to `.gitea/workflows`

+"""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)
+#
+# Optional:
+#   REVIEW_CHECK_DEBUG=1 — per-API-call diagnostic lines
+#   REVIEW_CHECK_STRICT=1 — also require review.commit_id == pr.head.sha

+#
+# Invoked by .gitea/workflows/sop-checklist-gate.yml on:
+#   - pull_request_target: [opened, edited, synchronize, reopened]
+#   - issue_comment:       [created, edited, deleted]
+#
+# Flow:
+#   1. Load .gitea/sop-checklist-config.yaml (from BASE ref — trusted).
+#   2. GET /repos/{R}/pulls/{N}          — author, head.sha, tier label
+#   3. GET /repos/{R}/issues/{N}/comments — extract /sop-ack and /sop-revoke
+#   4. For each checklist item:
+#        a. Is the section marker present in PR body? (author answered)
+#        b. Is there ≥1 unrevoked /sop-ack from a non-author whose
+#           team-membership matches required_teams?
+#   5. POST /repos/{R}/statuses/{sha}    — context
+#      `sop-checklist / all-items-acked (pull_request)`,
+#      state=success | failure | pending, description=`acked: N/M …`.
+#
+# Trust boundary (mirrors RFC#324 §A4):
+#   This script is loaded from the BASE branch. The workflow's
+#   actions/checkout step pins ref=base.sha. PR-HEAD code is never
+#   executed. We only HTTP-call the Gitea API.
+#
+# Token scope:
+#   - read:repository / read:organization to enumerate PR + comments
+#     + team membership (Gitea 1.22.6 quirk: team-membership endpoint
+#     returns 403 if token owner is not in the team; see review-check.sh
+#     for the same gotcha — we surface the same fail-closed message).
+#   - write:repository for `POST /repos/{R}/statuses/{sha}`. Unlike
+#     RFC#324's pattern (which uses the JOB's own pass/fail as the
+#     status), we POST the status explicitly because the gate posts
+#     a single multi-item status with a richer description than a
+#     bare success/failure context can carry.
+#
+# Slug normalization rules (canonical form: kebab-case):
+#   - Lowercase
+#   - Whitespace + underscores → single dash
+#   - Strip non [a-z0-9-] characters
+#   - Collapse adjacent dashes
+#   - Strip leading/trailing dashes
+#   - If the result is a digit string (e.g. "1"), look up via
+#     config.items[*].numeric_alias to get the kebab-case slug.
+#
+#   Examples:
+#       "Comprehensive_Testing"  → "comprehensive-testing"
+#       "comprehensive testing"  → "comprehensive-testing"
+#       "1"                      → "comprehensive-testing"
+#       "Five-Axis-Review"       → "five-axis-review"
+#
+# Revoke semantics:
+#   /sop-revoke <slug> [reason] — most-recent comment per (slug, user)
+#   wins. So if Alice posts /sop-ack X then later /sop-revoke X, her ack
+#   for X is invalidated. Bob's prior /sop-ack X is unaffected. If Alice
+#   posts /sop-revoke X then later /sop-ack X again, the ack is restored.

+# sop-tier-check — verify a Gitea PR satisfies the §SOP-6 approval gate.
+#
+# Reads the PR's tier label, walks approving reviewers, and checks team
+# membership against the tier's approval expression. Passes only when
+# ALL clauses in the expression are satisfied by the set of approving
+# reviewers (AND-composition; internal#189).
+#
+# Expression syntax:
+#   "team-a"          — OR-set: any ONE of the comma-separated teams
+#   "team-a AND team-b" — AND: BOTH must each have ≥1 approver
+#   "(a,b,c)"         — OR-set wrapped in parens; same as "a,b,c"
+#
+# Example: "qa AND security AND (managers,ceo)" means:
+#   ≥1 approver in team "qa"  AND
+#   ≥1 approver in team "security"  AND
+#   ≥1 approver in team "managers" OR "ceo"
+#
+# Per the spec (internal#189), the hard gate here pairs with the
+# advisory gate of sop-conformance LLM-judge (internal#188): each
+# required-team click must reflect real verification (visible in review
+# body or A2A messages), not rubber-stamp APPROVE. Both gates together
+# close the "teammate clicks APPROVE without verifying" gap.
+#

+"""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`).

+#
+# Bug (PR #225 → still broken after PR #231):
+#   Line ~289 of sop-tier-check.sh used:
+#     _clause=$(echo "$_raw_clause" | tr -d '()' | tr ',' '\n' | tr -d '[:space:]' | grep -v '^$')
+#   `tr -d '[:space:]'` strips the newlines that `tr ',' '\n'` just
+#   inserted, collapsing "engineers,managers,ceo" into a single token
+#   "engineersmanagersceo". The for-loop then iterates ONCE on a name
+#   that matches no team, so every tier:low PR fails:
+#     ::error::clause [engineers/managers/ceo]: FAIL — no approving
+#     reviewer belongs to any of these teamsengineersmanagersceo
+#   (note also: missing separators in the error string is bug #2 —
+#    `_clause_names` used "${var:+, }$x" which OVERWRITES per iteration).
+#
+# Fix shape (this PR):
+#   _no_parens=${_raw_clause//[()]/}
+#   _clause=${_no_parens//,/ }    # comma -> space, bash word-split iterates
+#   _clause_names="${_clause_names}${_clause_names:+, }${_t}"  # APPEND, not overwrite
+#
+# This test extracts the splitter logic and asserts it produces the right
+# token list for each of the three tier expressions live in the script.

+#   T1: PR open + APPROVED via tier:low → script invokes sop-tier-check
+#       and POSTs status=success.
+#   T2: PR open + missing tier label → sop-tier-check exits non-zero;
+#       refire POSTs status=failure (description mentions failure).
+#   T3: PR open + tier:low but NO approving reviews → sop-tier-check
+#       exits non-zero; refire POSTs status=failure.
+#   T4: PR CLOSED → refire exits 0 with no status POST (no-op on closed).
+#   T5: Rate-limit — recent status update within 30s → refire skips,
+#       no new POST.
+#   T6 (yaml-lint): workflow `if:` expression contains author_association
+#       gate + slash-command-trigger gate + PR-not-issue gate.
+#   T7 (yaml-lint): workflow file is parseable YAML.
+#
+# Tests T1-T5 run the real script against a local-fixture HTTP server
+# (python http.server with a stub handler — `tests/_refire_fixture.py`)
+# so the script's Gitea API calls hit the fixture, not the real Gitea.
+#
+# Tests T6/T7 are pure YAML checks against the workflow file.
+#
+# Hostile-self-review (per feedback_assert_exact_not_substring):

+#                       Membership is probed at gate-time via
+#                       GET /api/v1/teams/{id}/members/{login}.
+#                       Team-id resolution happens at script start via
+#                       GET /api/v1/orgs/{org}/teams (cheap, one call).
+#   numeric_alias     — 1..7; lets reviewers type `/sop-ack 3` as a
+#                       shortcut for `/sop-ack staging-smoke`.
+#
+# WHY THESE TEAM MAPPINGS:
+#   The RFC table referenced persona-role names like `core-qa`,
+#   `core-be`, `core-devops` — these are individual Gitea user logins,
+#   not teams. The Gitea team-membership API is /teams/{id}/members/{u},
+#   so we need actual teams. Orchestrator preflight 2026-05-12 verified
+#   only these teams exist on molecule-ai: ceo(5), engineers(2),
+#   managers(6), qa(20), security(21), Owners(1), and bot teams. We
+#   map the RFC roles to the closest existing team and surface the
+#   mapping explicitly so it's reviewable.
+#
+# HOW TO EDIT:
+#   - Tightening: replace `engineers` with a smaller team after creating
+#     it (e.g. a new `senior-engineers` team if needed).
+#   - Loosening: add another team to required_teams (OR semantics).
+#   - Add an item: append to items list and document the slug below.
+#
+# AUTHOR SELF-ACK IS FORBIDDEN regardless of which team contains them
+# — the gate script enforces commenter != PR author before checking
+# team membership.

+# Hard gate (#2342): cron-driven full-lifecycle E2E that catches
+# regressions visible only at runtime — schema drift, deployment-pipeline
+# gaps, vendor outages, env-var rotations, DNS / CF / Railway side-effects.
+#
+# Why this gate exists:
+#   PR-time CI catches code-level regressions but not deployment-time or
+#   integration-time ones. Today's empirical data:
+#     • #2345 (A2A v0.2 silent drop) — passed all unit tests, broke at
+#       JSON-RPC parse layer between sender and receiver. Visible only
+#       to a sender exercising the full path.
+#     • RFC #2312 chat upload — landed on staging-branch but never
+#       reached staging tenants because publish-workspace-server-image
+#       was main-only. Caught by manual dogfooding hours after deploy.
+#   Both would have surfaced within 15-20 min of regression if a
+#   continuous synth-E2E was running.
+#
+# Cadence: every 20 min (3x/hour). The script is conservatively
+# bounded at 10 min wall-clock; even on degraded staging it should
+# finish before the next firing. cron-overlap is guarded by the
+# concurrency group below.
+#
+# Cost: ~3 runs/hour × 5-10 min × $0.008/min GHA = ~$0.50-$1/day.
+# Plus a fresh tenant provisioned + torn down each run (Railway +
+# AWS pennies). Negligible.
+#
+# Failure handling: when the run fails, the workflow exits non-zero
+# and GitHub's standard email/notification path fires. Operators
+# can subscribe to this workflow's failure channel for paging-grade
+# alerting.
+
+on:
+  schedule:
+    # Every 10 minutes, on :02 :12 :22 :32 :42 :52. Three constraints:
+    #   1. Stay off the top-of-hour. GitHub Actions scheduler drops
+    #      :00 firings under high load (own docs:
+    #      https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#schedule).
+    #      Prior history: cron was '0,20,40' (2026-05-02) — only :00
+    #      ever survived. Bumped to '10,30,50' (2026-05-03) on the
+    #      theory that further-from-:00 wins. Empirically 2026-05-04
+    #      that ALSO dropped to ~60 min effective cadence (only ~1
+    #      schedule fire per hour — see molecule-core#2726). Detection
+    #      latency was claimed 20 min, actual 60 min.
+    #   2. Avoid colliding with the existing :15 sweep-cf-orphans
+    #      and :45 sweep-cf-tunnels — both hit the CF API and we
+    #      don't want to fight for rate-limit tokens.
+    #   3. Avoid the :30 heavy slot (staging-smoke /30, sweep-aws-
+    #      secrets, sweep-stale-e2e-orgs every :15) — multiple
+    #      overlapping cron registrations on the same minute is part
+    #      of what GH drops under load.
+    # Solution: bump fires-per-hour 3 → 6 AND keep all slots in clean
+    # lanes (1-3 min away from any other cron). Even with empirically-
+    # observed ~67% GH drop ratio, 6 attempts/hour yields ~2 effective
+    # fires = ~30 min cadence; closer to the 20-min target than the
+    # current shape and provides a real degradation alarm if drops
+    # get worse.

+#   - Dropped `workflow_dispatch.inputs` (Gitea 1.22.6 parser rejects them
+#     per feedback_gitea_workflow_dispatch_inputs_unsupported).
+#   - Dropped `merge_group:` (no Gitea merge queue).

+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#
+# Extracted from ci.yml so workflow-level concurrency can protect this job

+# Trigger model (revised 2026-04-29):
+#
+# Always FIRES on push/pull_request to staging+main. Real work is gated
+# per-step on `needs.detect-changes.outputs.api` — when paths under
+# `workspace-server/`, `tests/e2e/`, or this workflow file haven't
+# changed, the no-op step alone runs and emits SUCCESS for the
+# `E2E API Smoke Test` check, satisfying branch protection without
+# spending CI cycles. See the in-job comment on the `e2e-api` job for
+# why this is one job (not two-jobs-sharing-name) and the 2026-04-29
+# PR #2264 incident that drove the consolidation.
+#
+# Parallel-safety (Class B Hongming-owned CICD red sweep, 2026-05-08)
+# -------------------------------------------------------------------
+# Same substrate hazard as PR #98 (handlers-postgres-integration). Our
+# Gitea act_runner runs with `container.network: host` (operator host
+# `/opt/molecule/runners/config.yaml`), which means:
+#
+#   * Two concurrent runs both try to bind their `-p 15432:5432` /
+#     `-p 16379:6379` host ports — the second postgres/redis FATALs
+#     with `Address in use` and `docker run` returns exit 125 with
+#     `Conflict. The container name "/molecule-ci-postgres" is already
+#     in use by container ...`. Verified in run a7/2727 on 2026-05-07.
+#   * The fixed container names `molecule-ci-postgres` / `-redis` (the
+#     pre-fix shape) collide on name AS WELL AS port. The cleanup-with-
+#     `docker rm -f` at the start of the second job KILLS the first
+#     job's still-running postgres/redis.
+#
+# Fix shape (mirrors PR #98's bridge-net pattern, adapted because
+# platform-server is a Go binary on the host, not a containerised
+# step):
+#
+#   1. Unique container names per run:
+#         pg-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
+#         redis-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
+#      `${RUN_ID}-${RUN_ATTEMPT}` is unique even across reruns of the
+#      same run_id.
+#   2. Ephemeral host port per run (`-p 0:5432`), then read the actual
+#      bound port via `docker port` and export DATABASE_URL/REDIS_URL
+#      pointing at it. No fixed host-port → no port collision.
+#   3. `127.0.0.1` (NOT `localhost`) in URLs — IPv6 first-resolve was
+#      the original flake fixed in #92 and the script's still IPv6-
+#      enabled.
+#   4. `if: always()` cleanup so containers don't leak when test steps
+#      fail.
+#
+# Issue #94 items #2 + #3 (also fixed here):
+#   * Pre-pull `alpine:latest` so the platform-server's provisioner
+#     (`internal/handlers/container_files.go`) can stand up its
+#     ephemeral token-write helper without a daemon.io round-trip.
+#   * Create `molecule-core-net` bridge network if missing so the
+#     provisioner's container.HostConfig {NetworkMode: ...} attach
+#     succeeds.
+# Item #1 (timeouts) — evidence on recent runs (77/3191, ae/4270, 0e/
+# 2318) shows Postgres ready in 3s, Redis in 1s, Platform in 1s when
+# they DO come up. Timeouts are not the bottleneck; not bumped.
+#
+# Item explicitly NOT fixed here: failing test `Status back online`
+# fails because the platform's langgraph workspace template image
+# (ghcr.io/molecule-ai/workspace-template-langgraph:latest) returns
+# 403 Forbidden post-2026-05-06 GitHub org suspension. That is a
+# template-registry resolution issue (ADR-002 / local-build mode) and
+# belongs in a separate change that touches workspace-server, not
+# this workflow file.

+# that silently failed in production for five days before migration 046
+# extended the workspace_status enum (see
+# workspace-server/migrations/046_workspace_status_awaiting_agent.up.sql).
+#
+# Why this is its own workflow (not folded into e2e-staging-saas.yml):
+#   - The full-saas harness defaults to runtime=hermes, never exercises
+#     external-runtime. Adding an `external` parameter to that script
+#     would force every push to staging through both lifecycles in
+#     series, doubling the EC2 cold-start budget.
+#   - The external lifecycle has unique timing (REMOTE_LIVENESS_STALE_AFTER
+#     window, 90s default + sweep interval), which we wait through
+#     deliberately. Folding it into hermes would make the long path
+#     even longer.
+#   - It can run in parallel with the hermes E2E since both create
+#     fresh tenant orgs with distinct slug prefixes (`e2e-ext-...` vs
+#     `e2e-...`).
+#
+# Triggers:
+#   - Push to staging when any source affecting external runtime,
+#     hibernation, or the migration set changes.
+#   - PR review for the same set.
+#   - Manual workflow_dispatch.
+#   - Daily cron at 07:30 UTC (catches drift on quiet days; staggered
+#     30 min after e2e-staging-saas.yml's 07:00 UTC cron).
+#

+# Ported from .github/workflows/e2e-staging-saas.yml on 2026-05-11 per RFC
+# internal#219 §1 sweep. Differences from the GitHub version:
+#   - Dropped `workflow_dispatch.inputs` (Gitea 1.22.6 parser rejects them
+#     per feedback_gitea_workflow_dispatch_inputs_unsupported).
+#   - Dropped `merge_group:` (no Gitea merge queue).
+#   - Dropped `environment:` blocks (Gitea has no environments).
+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#
+
+# Dedicated workflow that provisions a fresh staging org per run, exercises
+# the full workspace lifecycle (register → heartbeat → A2A → delegation →
+# HMA memory → activity → peers), then tears down and asserts leak-free.
+#
+# Why a separate workflow (not folded into ci.yml):
+#   - The run takes ~25-35 min (EC2 boot + cloudflared DNS + provision sweeps +
+#     agent bootstrap), way too slow for every PR.
+#   - Needs its own concurrency group so two pushes don't fight over the
+#     same staging org slug prefix.
+#   - Has its own required secrets (session cookie, admin token) that most
+#     PRs don't need to read.
+#
+# Triggers:
+#   - Push to main (regression guard — fires on merges to main, not on PR updates)
+#   - pull_request: pr-validate always posts success; real E2E step runs only
+#     when provisioning-critical files change (detect-changes gates the step).
+#   - workflow_dispatch (manual re-run from UI)
+#   - Nightly cron (catches drift even when no pushes land)
+#
+# NOTE: A separate pr-validate job handles the pull_request path so this
+# workflow posts CI status for workflow-only PRs. Without it, a PR that
+# only touches the workflow file has no status check (workflow only fires
+# on push, not PR branches), which blocks merge under branch protection.
+# The E2E step itself only runs when provisioning-critical files change —
+# pr-validate always posts success, avoiding the double-fire that motivated
+# the pull_request-trigger removal in PRs #516/#530.

+#
+# Why this workflow exists
+# ------------------------
+# Strict-sqlmock unit tests pin which SQL statements fire — they're fast
+# and let us iterate without a DB. But sqlmock CANNOT detect bugs that
+# depend on the row state AFTER the SQL runs. The result_preview-lost
+# bug shipped to staging in PR #2854 because every unit test was
+# satisfied with "an UPDATE statement fired" — none verified the row's
+# preview field actually landed. The local-postgres E2E that retrofit
+# self-review caught it took 2 minutes to set up and would have caught
+# the bug at PR-time.
+#
+# Why this workflow does NOT use `services: postgres:` (Class B fix)
+# ------------------------------------------------------------------
+# Our act_runner config has `container.network: host` (operator host
+# /opt/molecule/runners/config.yaml), which act_runner applies to BOTH
+# the job container AND every service container. With host-net, two
+# concurrent runs of this workflow both try to bind 0.0.0.0:5432 — the
+# second postgres FATALs with `could not create any TCP/IP sockets:
+# Address in use`, and Docker auto-removes it (act_runner sets
+# AutoRemove:true on service containers). By the time the migrations
+# step runs `psql`, the postgres container is gone, hence
+# `Connection refused` then `failed to remove container: No such
+# container` at cleanup time.
+#
+# Per-job `container.network` override is silently ignored by
+# act_runner — `--network and --net in the options will be ignored.`
+# appears in the runner log. Documented constraint.
+#
+# So we sidestep `services:` entirely. The job container still uses
+# host-net (inherited from runner config; required for cache server

+# Boots tests/harness (production-shape compose topology with TenantGuard,
+# /cp/* proxy, canvas proxy, real production Dockerfile.tenant) and runs
+# every replay under tests/harness/replays/. Fails the PR if any replay
+# fails.
+#
+# Why this exists: 2026-04-30 we shipped #2398 which added /buildinfo as
+# a public route in router.go but forgot to add it to TenantGuard's
+# allowlist. The handler-level test in buildinfo_test.go constructed a
+# minimal gin engine without TenantGuard — green. The harness's
+# buildinfo-stale-image.sh replay would have caught it (cf-proxy doesn't
+# inject X-Molecule-Org-Id, so the curl path is identical to production's
+# redeploy verifier), but no one ran the harness pre-merge. The bug
+# shipped; the redeploy verifier silently soft-warned every tenant as
+# "unreachable" for ~1 day before being noticed.

+# Tier 2f scheduled lint (per mc#774) — detects drift between
+# `branch_protections/<branch>.status_check_contexts` and the set of
+# contexts emitted by `.gitea/workflows/*.yml`.
+#
+# Rule
+# ----
+# For each protected branch context (Source A — BP), there must exist
+# at least one emitting workflow + job pair (Source B — workflow YAML
+# + on:-event mapping) whose runtime status-name maps to it. The
+# inverse direction (emitter without BP context) is informational
+# only — Tier 2g handles that at PR-time.
+#
+# Why this exists
+# ---------------
+# A BP-required context with no emitter blocks merges forever — Gitea
+# 1.22.6 treats absent-as-`pending`, NOT absent-as-`skipped`. The
+# phantom-required-check class previously surfaced as
+# `feedback_phantom_required_check_after_gitea_migration` (a port
+# kept the GitHub context name after rename to Gitea, but no
+# workflow emitted under the new name).
+#
+# This lint catches the same class structurally + a forward case:
+# workflow renamed/deleted while still in BP.
+#
+# Scope
+# -----
+# Scheduled daily. We DON'T run on `pull_request` because (a) the
+# emitter side moves with PR diffs (transitional state false-flags)
+# and (b) Tier 2g handles emitter-side drift at PR-time.
+#
+# Cross-repo
+# ----------
+# Today this runs only on molecule-core/main. Per internal#349
+# (cross-repo BP sweep) Class-D repos will get the same lint after
+# their BP rollouts.
+#
+# Auth
+# ----
+# `GET /repos/.../branch_protections/{branch}` requires repo-admin
+# role on Gitea 1.22.6. We use DRIFT_BOT_TOKEN (same persona as
+# ci-required-drift.yml — `internal#329` provisioning trail).
+# Graceful-degrade per Tier 2a contract: 403/404 → exit 0 with
+# ::error::.
+#
+# Idempotency
+# -----------
+# The drift issue is filed with title prefix
+# `[ci-bp-drift] {repo}/{branch}: BP→emitter mismatch`. The script
+# searches OPEN issues for an exact title-prefix match and PATCHes
+# the existing issue (if any) instead of POSTing a duplicate.

+# Tier 2e hard-gate lint (per mc#774) — every
+# `continue-on-error: true` in `.gitea/workflows/*.yml` must carry a
+# `# mc#NNNN` or `# internal#NNNN` tracker comment within 2 lines,
+# the referenced issue must be OPEN, and ≤14 days old.
+#
+# Why this exists
+# ---------------
+# `continue-on-error: true` on `platform-build` had been hiding
+# mc#774-class regressions for ~3 weeks before #656 surfaced them on
+# 2026-05-12. A 14-day cap on tracker age forces a review cycle and
+# surfaces mask-drift within at most 14 days of the original defect.
+# Each `continue-on-error: true` gets a paper trail — close or renew.
+#
+# How the gate works
+# ------------------
+# 1. Walk `.gitea/workflows/*.yml` via PyYAML's line-tracking loader
+#    (per `feedback_behavior_based_ast_gates`) and find every job
+#    whose `continue-on-error` evaluates truthy (`true` or string
+#    `"true"` — Gitea's evaluator coerces strings).
+# 2. For each, scan ±2 lines of the directive's source line for a
+#    `# mc#NNNN` or `# internal#NNNN` comment. Inline-trailing
+#    comments on the directive line count.
+# 3. For each tracker reference, GET the issue from the Gitea API.
+#    Validate: exists, `state == open`, `created_at` ≤ MAX_AGE_DAYS.
+# 4. Aggregate ALL violations (not short-circuit) and exit 1 if any.
+#
+# Triggers
+# --------
+# Runs on PR events (paths-filter on `.gitea/workflows/**`) AND on
+# a daily schedule. PR runs catch the violation at introduction time.
+# Schedule runs catch the AGE-EXPIRY class: a tracker that was ≤14d
+# old when the PR landed but is now 20d old, with the underlying
+# defect still unfixed. Per `feedback_chained_defects_in_never_tested_workflows`,
+# scheduled drift detection is the second half of the gate.
+#
+# Phase contract (RFC internal#219 §1 ladder)
+# -------------------------------------------
+# Lands at `continue-on-error: true` (Phase 3 — surface broken shapes
+# without blocking). The pre-existing `continue-on-error: true`
+# directives on `main` will all violate this lint at first
+# (intentional — they're the masked defects this lint exists to
+# surface). Each must be triaged: file a fresh tracker comment,
+# close-and-flip, or document the deliberate keep-mask in a fresh
+# 14-day-renewable tracker. After main is clean for 3 days,
+# follow-up PR flips this workflow's continue-on-error to false.

+# Tier 2d hard-gate lint (per mc#774) — blocks PRs that touch
+# `.gitea/workflows/ci.yml` and modify ONLY ONE of {continue-on-error,
+# all-required.sentinel.needs} without a `Paired: #NNN` reference in
+# the PR body or in a commit message.
+#
+# Why this exists
+# ---------------
+# PR#665 (interim `continue-on-error: true` on `platform-build`) and
+# PR#668 (sentinel-`needs` demotion of the same job) were designed as a
+# pair but merged solo — #665 landed at 04:47Z 2026-05-12, #668 was
+# still open at 05:07Z when the main-red watchdog (#674) fired. Result:
+# ~20 minutes of `main` red and a cascade of false-positives on
+# unrelated PRs. This lint structurally prevents that class.
+#
+# How the gate works
+# ------------------
+# 1. The workflow runs on every PR whose diff touches ci.yml (paths
+#    filter). It is NOT a required check on `main` because the rule is
+#    diff-based — running it on PRs that don't touch ci.yml would
+#    produce a `pending` status forever (per
+#    `feedback_path_filtered_workflow_cant_be_required`).
+# 2. The script reads `BASE_SHA:ci.yml` and `HEAD_SHA:ci.yml`, parses
+#    both via PyYAML AST (per `feedback_behavior_based_ast_gates` — no
+#    grep, no regex on the raw text — so a YAML-shape refactor still
+#    detects).
+# 3. Walks `jobs.*.continue-on-error` on each side; flags any value
+#    diff. Reads `jobs.all-required.needs` on each side; flags any
+#    set diff (order-insensitive — `needs:` is engine-unordered).
+# 4. If both predicates fired → atomic, OK. If neither → no risk, OK.
+#    If exactly one fired → require `Paired: #NNN` in PR body OR in
+#    any commit message between base..head; else fail.
+#
+# Phase contract (RFC internal#219 §1 ladder)
+# -------------------------------------------
+# This workflow lands at `continue-on-error: true` (Phase 3 — surface
+# regressions without blocking PRs while the rule beds in).
+# Follow-up PR flips to `false` once we have ≥3 days of clean runs on
+# `main` and no false-positives. Tracking issue: mc#774.

+# on any job in `.gitea/workflows/*.yml` WITHOUT proof that the affected
+# job's recent runs on the target branch (PR base) are actually green.
+#
+# Empirical class: PR #656 / mc#774. PR #656 (RFC internal#219 Phase 4)
+# flipped 5 platform-build-class jobs `continue-on-error: true → false`
+# on the basis of a "verified green on main via combined-status check".
+# But that "green" was the LIE the prior `continue-on-error: true`
+# produced: Gitea Quirk #10 (internal#342 + dup #287) — a failed step
+# inside a `continue-on-error: true` job rolls up to a `success`
+# job-level status. The precondition the PR claimed to verify was
+# structurally fooled by the bug being flipped.
+#
+# mc#774 captured the surfaced defects (2 mutually-masked regressions):
+#   - Class 1: sqlmock helper drift since 2f36bb9a (24 days old)
+#   - Class 2: OFFSEC-001 contract collision since 7d1a189f (1 day old)
+#
+# Codified 04:35Z as hongming-pc2 charter §SOP-N rule (e)
+# "run-log-grep-before-flip" — now structurally enforced here at PR
+# time, ahead of merge.
+#
+# How the gate works:
+#   1. Read every `.gitea/workflows/*.yml` at the PR base SHA AND at
+#      the PR head SHA via `git show <sha>:<path>` (no checkout
+#      needed).
+#   2. Parse both sides via PyYAML AST (NOT grep — per
+#      `feedback_behavior_based_ast_gates`). Walk `jobs.<key>.
+#      continue-on-error` on each side. A flip is base=true,
+#      head=false.
+#   3. For each flipped job, render the commit-status context as
+#      `"{workflow.name} / {job.name or job.key} (push)"` — that's
+#      how Gitea Actions emits the per-context status on `main`/
+#      `staging` runs.
+#   4. Pull last 5 commits on the PR base branch, fetch combined
+#      commit-status per commit, scan for the target context. For
+#      each match, fetch the run log via the web-UI route
+#      `{server_url}/{repo}/actions/runs/{run_id}/jobs/{job_idx}/logs`
+#      (per `reference_gitea_actions_log_fetch` —
+#      Gitea 1.22.6 lacks REST `/actions/runs/*`; web-UI is the
+#      only working path, see also
+#      `reference_gitea_1_22_6_lacks_rest_rerun_endpoints`).
+#   5. Grep each log for `--- FAIL`, `FAIL\s`, `::error::`. If
+#      the status is `success` but the log shows any of these,
+#      the job was masked. Block the PR with `::error::`.
+#
+# Graceful-degrade contract (per task halt-conditions):
+#   - Log fetch 404 (act_runner pruned the log, transient outage):
+#     emit `::warning::` "log unavailable" — does NOT block.
+#   - Zero recent runs of the flipped job's context on the base
+#     branch (newly added workflow): emit `::warning::` "no run
+#     history to verify" — allow the flip. Chicken-and-egg
+#     exemption.
+#   - YAML parse error in one of the workflow files: warn-only,
+#     don't block — the YAML lint workflows catch this separately.

+# check. When a PR adds a NEW commit-status emission (workflow YAML
+# `name:` + job `name:`-or-key + on:-event), the workflow file must
+# carry one of three directives adjacent to the new job:
+#
+#   - `# bp-required: yes`           — and BP must list the context

+# Default (no directive on a new emitter) = FAIL.
+#
+# Why this exists
+# ---------------
+# PR#656 added `CI / all-required (pull_request)` as a sentinel
+# context that workflows emit, but BP did NOT list it. When
+# platform-build failed, all-required failed, but BP let the PR
+# merge anyway → cascade to mc#774. With this lint, PR#656 would
+# have been blocked until either the BP PATCH ran alongside OR

+#
+# Tier 2g vs Tier 2f
+# ------------------
+# Tier 2g runs at PR-time (diff-based) and BLOCKS the merge.
+# Tier 2f runs daily (scheduled) and FILES a drift issue. They
+# share the workflow-context enumeration helpers
+# (`_event_map`, `workflow_contexts`, `_job_display`) but the
+# semantics are intentionally distinct so they're separate scripts.
+# Co-design is documented in mc#774.
+#
+# Directive comment lives in the workflow file (NOT PR body)
+# ----------------------------------------------------------
+# A PR-body claim of "BP exempt" evaporates on merge — the
+# asymmetry returns to undetected state and Tier 2f's daily
+# scheduled audit can't see it. The directive must live with the

+#   Today (2026-05-11) molecule-core/main protects 3 contexts:
+#     - "Secret scan / Scan diff for credential-shaped strings (pull_request)"
+#     - "sop-tier-check / tier-check (pull_request)"
+#     - "CI / all-required (pull_request)"
+#   Per RFC#324 Step 2 the required-list expands to ~5 contexts
+#   (qa-review, security-review added). Each new required context's
+#   workflow must remain unconditional. This lint pins that contract.
+#
+# Meta-required-check:
+#   This workflow ITSELF deliberately has NO `paths:` filter on its `on:`
+#   block — otherwise a paths-non-matching PR could bypass the check.
+#   Self-evident from this file: only `pull_request` types + no paths.
+#
+# Auth:
+#   `GET /repos/.../branch_protections/{branch}` requires repo-admin
+#   role in Gitea 1.22.6. The workflow-default `GITHUB_TOKEN` is
+#   non-admin (read-only), so we re-use `DRIFT_BOT_TOKEN` (same persona
+#   that powers `ci-required-drift.yml` — verified working there).
+#   If `DRIFT_BOT_TOKEN` becomes unavailable, the script exits 0 with a
+#   loud `::error::` rather than red-X every PR — token-scope issues
+#   should be fixed at the token, not surfaced as a gate failure on
+#   every unrelated PR.
+#
+# Behavior-based gate per `feedback_behavior_based_ast_gates`:
+#   YAML AST walk (PyYAML), NOT grep. Workflow renames, formatting
+#   changes (block-scalar vs flow-style), or moving `paths:` between
+#   `pull_request:` and `pull_request_target:` all still detect.
+#
+# IMPORTANT — Gitea 1.22.6 parser quirk per
+# `feedback_gitea_workflow_dispatch_inputs_unsupported`: do NOT add an

+# Auto-bump-on-workspace-edit half of the publish pipeline.
+#
+# Why this file exists (issue #351):
+#   Gitea Actions does not correctly disambiguate `paths:` from `tags:`
+#   when both are bundled under a single `on.push` key. The result is
+#   that tag pushes get filtered out and `publish-runtime.yml` never
+#   fires — `action_run` rows: 0. This was unnoticed pre-2026-05-11
+#   because PYPI_TOKEN was absent (publishes would have failed anyway).
+#
+#   Split design:
+#     - publish-runtime.yml         : on.push.tags only        (the publisher)
+#     - publish-runtime-autobump.yml: on.push.branches+paths   (this file — the version-bumper)
+#
+#   This file computes the next version from PyPI's latest, pushes a
+#   `runtime-v$VERSION` tag, and exits. The tag push then triggers
+#   publish-runtime.yml via its tags-only trigger.
+#
+# Concurrency: shares the `publish-runtime` group with publish-runtime.yml
+# so concurrent workspace pushes serialize at the bump step. Without
+# this, two pushes minutes apart could both read PyPI latest=0.1.129
+# and try to tag 0.1.130 simultaneously, only one of which would land.

+# Gitea Actions port of .github/workflows/publish-runtime.yml.
+#
+# Ported 2026-05-10 (issue #206). Key differences from the GitHub version:
+#   - Gitea Actions reads .gitea/workflows/, not .github/workflows/
+#   - Dropped `environment: pypi-publish` — Gitea Actions does not support
+#     named environments or OIDC trusted publishers
+#   - Replaced `pypa/gh-action-pypi-publish@release/v1` (OIDC) with
+#     `twine upload` using PYPI_TOKEN secret — same mechanism as a local
+#     `python -m twine upload` with a PyPI token
+#   - Replaced `github.ref_name` (GitHub-only) with `${GITHUB_REF#refs/tags/}`
+#     — Gitea Actions exposes github.ref (the full ref) but not ref_name
+#   - Dropped `merge_group` trigger (Gitea has no merge queue)
+#
+# 2026-05-10 (issue #348): originally restored `staging`/`main` branch +
+# `workspace/**` path-filter trigger in PR #349.
+#
+# 2026-05-11 (issue #351): REVERTED the branches+paths trigger from THIS
+# file. Bundling `paths` with `tags` under a single `on.push` key caused
+# Gitea Actions to never dispatch the workflow for tag-push events (0
+# runs in `action_run` for workflow_id='publish-runtime.yml' since the
+# port, including the runtime-v1.0.0 tag — which is why PyPI is still at
+# 0.1.129 despite a v1.0.0 Gitea tag existing).
+#
+# The auto-bump-on-workspace-edit trigger now lives in
+# `.gitea/workflows/publish-runtime-autobump.yml`. That file computes the
+# next version from PyPI's latest and pushes a `runtime-v$VERSION` tag,
+# which THIS file then picks up via the tags-only trigger below.
+#
+# This decoupling means Gitea's path-vs-tag evaluator never has to
+# disambiguate — each file has a single unambiguous trigger shape.
+#
+# PyPI publishing: requires PYPI_TOKEN repository secret (or org-level secret).
+# Set via: repo Settings → Actions → Variables and Secrets → New Secret.
+# The token should be a PyPI API token scoped to molecule-ai-workspace-runtime.
+#
+# The DISPATCH_TOKEN cascade (git push to template repos) is unchanged —
+# it uses the Gitea API directly and was already Gitea-compatible.

+#   - Dropped `environment:` declarations — Gitea Actions does not support

+# 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

+# 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.

+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#   - ~~**Gitea workflow_run trigger limitation**~~ FIXED: replaced with
+#     push+paths filter per this PR. Gitea 1.22.6 does not support
+#     `workflow_run` (task #81). The push trigger fires on every
+#     commit to publish-workspace-server-image.yml which is the
+#     same signal (only successful runs commit to main).
+#
+
+# Auto-refresh prod tenant EC2s after every main merge.
+#
+# Why this workflow exists: publish-workspace-server-image builds and
+# pushes a new platform-tenant :<sha> to ECR on every merge to main,
+# but running tenants pulled their image once at boot and never re-pull.
+# Users see stale code indefinitely.
+#
+# This workflow closes the gap by calling the control-plane admin
+# endpoint that performs a canary-first, batched, health-gated rolling
+# redeploy across every live tenant. Implemented in molecule-ai/
+# molecule-controlplane as POST /cp/admin/tenants/redeploy-fleet
+# (feat/tenant-auto-redeploy, landing alongside this workflow).
+#
+# Registry: ECR (153263036946.dkr.ecr.us-east-2.amazonaws.com/
+# molecule-ai/platform-tenant). GHCR was retired 2026-05-07 during the
+# Gitea suspension migration. The staging-verify.yml promote step now
+# uses the same redeploy-fleet endpoint (fixes the silent-GHCR gap).
+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes → new :staging-<sha> in ECR.
+#   2. This workflow fires via workflow_run, calls redeploy-fleet with
+#      target_tag=staging-<sha>. No CDN propagation wait needed —
+#      ECR image manifest is consistent immediately after push.
+#   3. Calls redeploy-fleet with canary_slug (if set) and a soak
+#      period. Canary proves the image boots; batches follow.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.
+#
+# Rollback path: re-run this workflow with a specific SHA pinned via
+# the workflow_dispatch input. That calls redeploy-fleet with

+#   - Dropped `workflow_dispatch.inputs` (Gitea 1.22.6 parser rejects them
+#     per feedback_gitea_workflow_dispatch_inputs_unsupported).
+#   - Dropped `merge_group:` (no Gitea merge queue).
+#   - Dropped `environment:` blocks (Gitea has no environments).
+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#   - ~~**Gitea workflow_run trigger limitation**~~ FIXED: replaced with
+#     push+paths filter per this PR. Gitea 1.22.6 does not support
+#     `workflow_run` (task #81). The push trigger fires on every
+#     commit to publish-workspace-server-image.yml which is the
+#     same signal (only successful runs commit to main). Removed
+#     `workflow_run.conclusion==success` job if since push implies
+#     the workflow completed and committed.
+#
+
+# Auto-refresh staging tenant EC2s after every staging-branch merge.
+#
+# Mirror of redeploy-tenants-on-main.yml, with the staging-CP host and
+# the :staging-latest tag. Sister workflow exists for prod (rolls
+# :latest after staging-verify). Both share the same shape — just
+# different CP_URL + target_tag + admin token secret.
+#
+# Why this workflow exists: publish-workspace-server-image now builds
+# on every staging-branch push (PR #2335), pushing
+# platform-tenant:staging-latest to GHCR. Existing tenants pulled
+# their image once at boot and never re-pull, so the new image just
+# sits unused until the tenant is reprovisioned.
+#
+# This workflow closes the gap by calling staging-CP's
+# /cp/admin/tenants/redeploy-fleet, which performs a canary-first,
+# batched, health-gated SSM redeploy across every live staging tenant.
+# Same endpoint shape as prod CP — only the host differs.
+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes on staging branch →
+#      new :staging-latest in GHCR.
+#   2. This workflow fires via workflow_run, waits 30s for GHCR's CDN
+#      to propagate the new tag.
+#   3. Calls redeploy-fleet with no canary (staging IS canary; we don't
+#      need a sub-canary inside it). Soak still applies to the first
+#      tenant in case of bad-deploy detection.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.
+#
+# Rollback path: re-run with workflow_dispatch + target_tag=staging-<sha>

+name: Runtime PR-Built Compatibility
+
+# 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.

+# sop-checklist-gate — peer-ack merge gate for SOP-checklist items.
+#
+# RFC#351 Step 2 of 6 (implementation MVP).
+#
+# === DESIGN ===
+#
+# Goal: each PR must answer 7 SOP-checklist questions in its body,
+# and each item must have at least one /sop-ack <slug> comment from
+# a non-author peer in the required team. BP requires the
+# `sop-checklist / all-items-acked (pull_request)` status to merge.
+#
+# Triggers:
+#   - `pull_request_target`: opened, edited, synchronize, reopened
+#       → fires when PR opens, body is edited (refire — RFC#351 §4),
+#         or new code is pushed (head.sha changes → stale status would
+#         be auto-discarded by BP via dismiss_stale_reviews, but the
+#         status itself is per-SHA so we re-post on the new head).
+#   - `issue_comment`: created, edited, deleted
+#       → fires on any new comment so /sop-ack / /sop-revoke take
+#         effect immediately (Gitea 1.22.6 doesn't refire on
+#         pull_request_review per feedback_pull_request_review_no_refire,
+#         so issue_comment is the canonical refire channel).
+#
+# Trust boundary (mirrors RFC#324 §A4 + sop-tier-check security note):
+#   `pull_request_target` (not `pull_request`) — workflow def is loaded
+#   from BASE branch, so a PR cannot rewrite this workflow to exfiltrate
+#   the token. The `actions/checkout` step pins `ref: base.sha` so the
+#   script ALSO comes from BASE. PR-HEAD code is never executed in the
+#   runner.
+#
+# Token scope:
+#   - read:repository, read:organization for PR + comments + team probes
+#   - write:repository for POST /statuses/{sha}
+#   - The token owner MUST be a member of every team referenced by the
+#     config's required_teams (else /teams/{id}/members/{login} returns
+#     403 — see review-check.sh same-gotcha doc). For the MVP we use
+#     the dev-lead token (a member of engineers, managers, qa, security)
+#     via a repo secret `SOP_CHECKLIST_GATE_TOKEN`. Provisioning of that
+#     secret is a follow-up authorization step (separate from this PR).
+#
+# Failure mode: tier-aware (RFC#351 open question 2):
+#   - tier:high   → state=failure (hard-fail; BP blocks merge)
+#   - tier:medium → state=failure (hard-fail; same)
+#   - tier:low    → state=pending (soft-fail; BP can choose to require
+#                    this context or skip for low-tier PRs)
+#   - missing/no-tier → state=failure (default-mode: hard — never lower
+#                    the bar per feedback_fix_root_not_symptom)
+#
+# Slash-command contract (RFC#351 v1 + §A1.1-style notes from RFC#324):
+#
+#   /sop-ack <slug-or-numeric-alias> [optional note]
+#       — register a peer-ack for one checklist item.
+#       — slug accepts kebab-case, snake_case, or natural-spaces
+#         (all normalize to canonical kebab-case).
+#       — numeric 1..7 maps via config.items[*].numeric_alias.
+#       — most-recent (user, slug) directive wins.
+#
+#   /sop-revoke <slug-or-numeric-alias> [reason]
+#       — invalidate the commenter's own prior /sop-ack for this slug.
+#       — does NOT affect other peers' acks on the same slug.
+#       — most-recent (user, slug) directive wins, so a later /sop-ack
+#         re-restores the ack.
+#
+# The eval is read-only + idempotent (read PR + comments + team
+# membership, compute, post status). Re-running on any event is safe —
+# the new status overwrites the previous one for the same context.

+# sop-tier-refire — issue_comment-triggered refire of sop-tier-check.
+#
+# Closes internal#292. Gitea 1.22.6 doesn't refire workflows on the
+# `pull_request_review` event (go-gitea/gitea#33700); the `sop-tier-check`
+# workflow's review-event subscription is silently dead. The result:
+# PRs that get their approving review AFTER the tier-check ran on open/
+# synchronize keep their failing status check forever, and the only way
+# to merge is the admin force-merge path (audited via `audit-force-merge`
+# but the audit trail keeps growing; see `feedback_never_admin_merge_bypass`).
+#
+# Workaround pattern from `feedback_pull_request_review_no_refire`:
+# `issue_comment` events DO fire reliably on 1.22.6. When a repo
+# MEMBER/OWNER/COLLABORATOR comments `/refire-tier-check` on a PR, this
+# workflow re-runs the sop-tier-check logic and POSTs the resulting
+# status to the PR head SHA directly. No empty commit, no git history
+# bloat, no cascade re-fire of every other workflow on the PR.
+#
+# SECURITY MODEL:
+#
+# 1. `pull_request` exists on the issue (issue_comment fires on issues
+#    AND PRs; we only want PRs).
+# 2. `comment.author_association` must be MEMBER/OWNER/COLLABORATOR.
+#    Per the internal#292 core-security review (review#1066 ask): anyone
+#    can comment, but only repo collaborators+ can flip the status.
+#    Without this gate, a drive-by commenter on a public-issue-tracker
+#    surface could trigger a status flip.
+# 3. Comment body must contain `/refire-tier-check` — a slash-command-
+#    shaped trigger (not just any comment word). Prevents accidental
+#    triggering from prose like "we should refire tests" in a review.
+# 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.
+#
+# Rate-limit: a 1s pre-sleep + a "skip if status posted in last 30s"

+# Renamed from canary-verify.yml on 2026-05-11 per Hongming directive
+# ("canary naming changed to staging for all"). Originally ported from
+# .github/workflows/canary-verify.yml on 2026-05-11 per RFC
+# internal#219 §1 sweep. Differences from the GitHub version:
+#   - Dropped `workflow_dispatch.inputs` (Gitea 1.22.6 parser rejects them
+#     per feedback_gitea_workflow_dispatch_inputs_unsupported).
+#   - Dropped `merge_group:` (no Gitea merge queue).
+#   - Dropped `environment:` blocks (Gitea has no environments).
+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#   - ~~**Gitea workflow_run trigger limitation**~~ FIXED: replaced with
+#     push+paths filter per this PR. Gitea 1.22.6 does not support
+#     `workflow_run` (task #81). The push trigger fires on every
+#     commit to publish-workspace-server-image.yml. Removed the
+#     `workflow_run.conclusion==success` job if since the push trigger
+#     doesn't carry completion state — the smoke test is the safety net
+#     (it will detect and abort on a bad image regardless). Added
+#     workflow_dispatch for manual runs.
+#
+
+# Runs the canary smoke suite against the staging canary tenant fleet
+# after a new :staging-<sha> image lands in ECR. On green, calls the
+# CP redeploy-fleet endpoint to promote :staging-<sha> → :latest so
+# the prod tenant fleet's 5-minute auto-updater picks up the verified
+# digest. On red, :latest stays on the prior known-good digest and
+# prod is untouched.
+#
+# Terminology note (2026-05-11): The deployment STRATEGY here is still
+# called "canary release" (a small subset of tenants gets the new image
+# first, the rest follow on green). The "canary" word stays for the
+# pre-fan-out cohort concept (see docs/architecture/canary-release.md
+# and CANARY_SLUG in redeploy-tenants-on-*.yml). What changed is the
+# FILE NAME and the SECRETS feeding this workflow — both are renamed
+# to drop the redundant "canary-" prefix that conflated workflow
+# identity with deployment strategy.
+#
+# Registry note (2026-05-10): This workflow previously used GHCR
+# (ghcr.io/molecule-ai/platform-tenant) — that registry was retired
+# during the 2026-05-06 Gitea suspension migration when publish-
+# workspace-server-image.yml switched to the operator's ECR org
+# (153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/
+# platform-tenant). The GHCR → ECR migration was never applied to
+# this file, so this workflow was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
+#     agnostic, works regardless of registry).
+#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=
+#     staging-<sha>, same mechanism as redeploy-tenants-on-main.yml.
+#     No longer attempts GHCR crane ops.
+#
+# Dependencies:
+#   - publish-workspace-server-image.yml publishes :staging-<sha>
+#     to ECR on staging and main merges.
+#   - Canary tenants are configured to pull :staging-<sha> from ECR
+#     (TENANT_IMAGE env set to the ECR :staging-<sha> tag).
+#   - Repo secrets MOLECULE_STAGING_TENANT_URLS /
+#     MOLECULE_STAGING_ADMIN_TOKENS / MOLECULE_STAGING_CP_SHARED_SECRET
+#     are populated.

+#
+# 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)

+# (`molecule/tenant/<org_id>/bootstrap`) whose backing tenant no
+# longer exists. Parallel-shape to sweep-cf-tunnels.yml and
+# sweep-cf-orphans.yml — different cloud, same justification.
+#
+# Why this exists separately from a long-term reconciler integration:
+#   - molecule-controlplane's tenant_resources audit table (mig 024)
+#     currently tracks four resource kinds: CloudflareTunnel,
+#     CloudflareDNS, EC2Instance, SecurityGroup. SecretsManager is
+#     not in the list, so the existing reconciler doesn't catch
+#     orphan secrets.
+#   - At ~$0.40/secret/month the cost grew to ~$19/month before this
+#     sweeper was written, indicating ~45+ orphan secrets from
+#     crashed provisions and incomplete deprovision flows.
+#   - The proper fix (KindSecretsManagerSecret + recorder hook +
+#     reconciler enumerator) is filed as a separate controlplane
+#     issue. This sweeper is the immediate cost-relief stopgap.
+#
+# AWS credentials: use the dedicated Secrets Manager janitor principal.
+# Do not fall back to the molecule-cp application principal: it does
+# not need account-wide ListSecrets, and a 2026-05-12 CI failure proved
+# that using it here turns a least-privilege production credential into
+# a red scheduled janitor.
+#
+# Safety: the script's MAX_DELETE_PCT gate (default 50%, mirroring
+# sweep-cf-orphans.yml — tenant secrets are durable by design, unlike
+# the mostly-orphan tunnels) refuses to nuke past the threshold.
+
+on:
+  schedule:
+    # Hourly at :30 — offsets from sweep-cf-orphans (:15) and

+# Janitor for Cloudflare DNS records whose backing tenant/workspace no
+# longer exists. Without this loop, every short-lived E2E or canary
+# leaves a CF record on the moleculesai.app zone — the zone has a
+# 200-record quota (controlplane#239 hit it 2026-04-23+) and provisions
+# start failing with code 81045 once exhausted.
+#
+# Why a separate workflow vs sweep-stale-e2e-orgs.yml:
+#   - That workflow operates at the CP layer (DELETE /cp/admin/tenants/:slug
+#     drives the cascade). It assumes CP has the org row to drive the
+#     deprovision from. It doesn't catch records left behind when CP
+#     itself never knew about the tenant (canary scratch, manual ops
+#     experiments) or when the cascade's CF-delete branch failed.
+#   - sweep-cf-orphans.sh enumerates the CF zone directly and matches
+#     each record against live CP slugs + AWS EC2 names. It catches
+#     leaks the CP-driven sweep can't.
+#
+# Safety: the script's own MAX_DELETE_PCT gate refuses to nuke more
+# than 50% of records in a single run. If something has gone weird
+# (CP admin endpoint returns no orgs → every tenant looks orphan) the
+# gate halts before damage. Decision-function unit tests in
+# scripts/ops/test_sweep_cf_decide.py (#2027) cover the rule
+# classifier.
+#
+# Secrets: CF_API_TOKEN, CF_ZONE_ID, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY
+# are confirmed existing per issue #425 §425 audit. CP_ADMIN_API_TOKEN and
+# CP_STAGING_ADMIN_API_TOKEN are unconfirmed — if missing, the verify step
+# (schedule → hard-fail, dispatch → soft-skip) surfaces it clearly.

+# Dependabot — auto-bump pinned dependencies.
+#
+# Why this exists:
+#
+# All `uses:` references in .github/workflows/*.yml are pinned to commit
+# SHAs (with `# v<N>` comments for human readability) instead of mutable
+# tags like `@v4`. Tag pinning is a known supply-chain risk: a maintainer
+# (or compromised maintainer account) can repoint `@v4` to malicious code
+# and our pipelines silently pull it. SHA pinning closes that risk.
+#
+# But SHA pinning has a maintenance cost: each upstream legitimate fix
+# requires manually finding + bumping the SHA. Dependabot for Actions
+# closes that gap by opening PRs to bump pinned SHAs whenever upstream
+# tags a new version. Reviewer evaluates the bump like any other
+# dependency PR.

-name: Auto-sync main → staging
-
-# Reflects every push to `main` back onto `staging` so the
-# staging-as-superset-of-main invariant holds.
-#
-# Background:
-#
-# `auto-promote-staging.yml` advances main via `git merge --ff-only`
-# + `git push origin main` — that's a clean fast-forward, no merge
-# commit. But manual merges of `staging → main` PRs through the
-# GitHub UI / API create a merge commit on main that staging
-# doesn't have. The next `staging → main` PR then evaluates as
-# "BEHIND" because staging is missing that merge commit, requiring
-# a manual `gh pr update-branch` round-trip.
-#
-# This happened twice on 2026-04-28 (PRs #2202, #2205, both manual
-# bridges). Each time the bridge needed update-branch + a re-CI
-# round before merging. Operationally annoying and avoidable.
-#
-# This workflow closes the gap automatically:
-#
-#   1. Push to main fires (regardless of source: auto-promote, UI
-#      merge, API merge, direct push).
-#   2. Check whether main is already in staging's ancestry — if
-#      yes, no-op (auto-promote-staging already kept them in sync
-#      via fast-forward).
-#   3. If not, try fast-forward staging to main first (works when
-#      staging hasn't diverged with its own commits).
-#   4. If ff fails (staging has commits main doesn't — feature work
-#      in flight), do a real merge with a "chore: sync" commit so
-#      staging absorbs main's tip while keeping its own history.
-#   5. Push staging.
-#
-# Loop safety:
-#
-# `GITHUB_TOKEN`-authored pushes do NOT trigger downstream workflow
-# runs by default (GitHub Actions safety). So when this workflow
-# pushes the synced staging, `auto-promote-staging.yml` is NOT
-# triggered by that push. The next developer push to staging triggers
-# auto-promote normally. No loop is even theoretically possible.
-#
-# Concurrency:
-#
-# Two pushes to main in quick succession (e.g., manual UI merge
-# immediately followed by auto-promote-staging's ff-merge) would
-# otherwise race two auto-sync runs against the same staging branch
-# — second push fails non-fast-forward. The concurrency group
-# serializes them so the second run sees the first's result.

+# this file, so canary-verify was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-

+# Hard gate (#2342): cron-driven full-lifecycle E2E that catches
+# regressions visible only at runtime — schema drift, deployment-pipeline
+# gaps, vendor outages, env-var rotations, DNS / CF / Railway side-effects.
+#
+# Why this gate exists:
+#   PR-time CI catches code-level regressions but not deployment-time or
+#   integration-time ones. Today's empirical data:
+#     • #2345 (A2A v0.2 silent drop) — passed all unit tests, broke at
+#       JSON-RPC parse layer between sender and receiver. Visible only
+#       to a sender exercising the full path.
+#     • RFC #2312 chat upload — landed on staging-branch but never
+#       reached staging tenants because publish-workspace-server-image
+#       was main-only. Caught by manual dogfooding hours after deploy.
+#   Both would have surfaced within 15-20 min of regression if a
+#   continuous synth-E2E was running.
+#
+# Cadence: every 20 min (3x/hour). The script is conservatively
+# bounded at 10 min wall-clock; even on degraded staging it should
+# finish before the next firing. cron-overlap is guarded by the
+# concurrency group below.
+#
+# Cost: ~3 runs/hour × 5-10 min × $0.008/min GHA = ~$0.50-$1/day.
+# Plus a fresh tenant provisioned + torn down each run (Railway +
+# AWS pennies). Negligible.
+#
+# Failure handling: when the run fails, the workflow exits non-zero
+# and GitHub's standard email/notification path fires. Operators
+# can subscribe to this workflow's failure channel for paging-grade
+# alerting.
+
+on:
+  schedule:
+    # Every 10 minutes, on :02 :12 :22 :32 :42 :52. Three constraints:
+    #   1. Stay off the top-of-hour. GitHub Actions scheduler drops
+    #      :00 firings under high load (own docs:
+    #      https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#schedule).
+    #      Prior history: cron was '0,20,40' (2026-05-02) — only :00
+    #      ever survived. Bumped to '10,30,50' (2026-05-03) on the
+    #      theory that further-from-:00 wins. Empirically 2026-05-04
+    #      that ALSO dropped to ~60 min effective cadence (only ~1
+    #      schedule fire per hour — see molecule-core#2726). Detection
+    #      latency was claimed 20 min, actual 60 min.
+    #   2. Avoid colliding with the existing :15 sweep-cf-orphans
+    #      and :45 sweep-cf-tunnels — both hit the CF API and we
+    #      don't want to fight for rate-limit tokens.
+    #   3. Avoid the :30 heavy slot (canary-staging /30, sweep-aws-
+    #      secrets, sweep-stale-e2e-orgs every :15) — multiple
+    #      overlapping cron registrations on the same minute is part
+    #      of what GH drops under load.
+    # Solution: bump fires-per-hour 3 → 6 AND keep all slots in clean
+    # lanes (1-3 min away from any other cron). Even with empirically-
+    # observed ~67% GH drop ratio, 6 attempts/hour yields ~2 effective
+    # fires = ~30 min cadence; closer to the 20-min target than the
+    # current shape and provides a real degradation alarm if drops

+name: E2E Staging External Runtime
+
+# Regression for the four/five workspaces.status=awaiting_agent transitions
+# that silently failed in production for five days before migration 046
+# extended the workspace_status enum (see
+# workspace-server/migrations/046_workspace_status_awaiting_agent.up.sql).
+#
+# Why this is its own workflow (not folded into e2e-staging-saas.yml):
+#   - The full-saas harness defaults to runtime=hermes, never exercises
+#     external-runtime. Adding an `external` parameter to that script
+#     would force every push to staging through both lifecycles in
+#     series, doubling the EC2 cold-start budget.
+#   - The external lifecycle has unique timing (REMOTE_LIVENESS_STALE_AFTER
+#     window, 90s default + sweep interval), which we wait through
+#     deliberately. Folding it into hermes would make the long path
+#     even longer.
+#   - It can run in parallel with the hermes E2E since both create
+#     fresh tenant orgs with distinct slug prefixes (`e2e-ext-...` vs
+#     `e2e-...`).
+#
+# Triggers:
+#   - Push to staging when any source affecting external runtime,
+#     hibernation, or the migration set changes.
+#   - PR review for the same set.
+#   - Manual workflow_dispatch.
+#   - Daily cron at 07:30 UTC (catches drift on quiet days; staggered
+#     30 min after e2e-staging-saas.yml's 07:00 UTC cron).
+#
+# Concurrency: serialized so two staging pushes don't fight for the
+# same EC2 quota window. cancel-in-progress=false so a half-rolled
+# tenant always finishes its teardown.

+name: Handlers Postgres Integration
+
+# Real-Postgres integration tests for workspace-server/internal/handlers/.
+# Triggered on every PR/push that touches the handlers package.
+#
+# Why this workflow exists
+# ------------------------
+# Strict-sqlmock unit tests pin which SQL statements fire — they're fast
+# and let us iterate without a DB. But sqlmock CANNOT detect bugs that
+# depend on the row state AFTER the SQL runs. The result_preview-lost
+# bug shipped to staging in PR #2854 because every unit test was
+# satisfied with "an UPDATE statement fired" — none verified the row's
+# preview field actually landed. The local-postgres E2E that retrofit
+# self-review caught it took 2 minutes to set up and would have caught
+# the bug at PR-time.
+#
+# Why this workflow does NOT use `services: postgres:` (Class B fix)
+# ------------------------------------------------------------------
+# Our act_runner config has `container.network: host` (operator host
+# /opt/molecule/runners/config.yaml), which act_runner applies to BOTH
+# the job container AND every service container. With host-net, two
+# concurrent runs of this workflow both try to bind 0.0.0.0:5432 — the
+# second postgres FATALs with `could not create any TCP/IP sockets:
+# Address in use`, and Docker auto-removes it (act_runner sets
+# AutoRemove:true on service containers). By the time the migrations
+# step runs `psql`, the postgres container is gone, hence
+# `Connection refused` then `failed to remove container: No such
+# container` at cleanup time.
+#
+# Per-job `container.network` override is silently ignored by
+# act_runner — `--network and --net in the options will be ignored.`
+# appears in the runner log. Documented constraint.
+#
+# So we sidestep `services:` entirely. The job container still uses
+# host-net (inherited from runner config; required for cache server
+# discovery on the bridge IP 172.18.0.17:42631). We launch a sibling
+# postgres on the existing `molecule-core-net` bridge with a
+# UNIQUE name per run — `pg-handlers-${RUN_ID}-${RUN_ATTEMPT}` — and
+# read its bridge IP via `docker inspect`. A host-net job container
+# can reach a bridge-net container directly via the bridge IP (verified
+# manually on operator host 2026-05-08).
+#
+# Trade-offs vs. the original `services:` shape:
+#   + No host-port collision; N parallel runs share the bridge cleanly
+#   + `if: always()` cleanup runs even on test-step failure
+#   - One more step in the workflow (+~3 lines)
+#   - Requires `molecule-core-net` to exist on the operator host
+#     (it does; declared in docker-compose.yml + docker-compose.infra.yml)
+#
+# Class B Hongming-owned CICD red sweep, 2026-05-08.
