test(canvas): add Toolbar component test coverage (19 cases)

Covers:
- Workspace count display (0 and N workspaces)
- Status pills: online/offline/failed/provisioning (shown/hidden correctly)
- WebSocket status pill: Live/Reconnecting/Offline
- Stop All button visibility based on activeTasks
- Restart Pending button visibility based on needsRestart flag
- Help popover open/close
- A2A edges toggle
- Keyboard shortcut (?) opens shortcuts dialog, suppressed in inputs

Follows the vi.fn() + mockStoreState pattern from BatchActionBar.test.tsx
with beforeEach reset to prevent cross-test state leakage.

-"""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.

-"""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.
-  7. Production deploy/redeploy workflows may not rely on Gitea
-     `concurrency.cancel-in-progress: false` for serialization. Gitea
-     1.22.6 can cancel queued runs despite that setting.
-  8. Production deploy/redeploy workflows may not dump raw CP responses or
-     raw `.error` fields into CI logs/summaries.
-  9. Production deploy/redeploy workflows must expose an operational control:
-     kill switch for auto deploys or rollback tag for manual deploys.
-  10. Docker health checks must not run `docker info | head` under pipefail.
-      `head` closes the pipe early, `docker info` can exit nonzero from
-      SIGPIPE, and the step can falsely report Docker daemon failure.
-
-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.
-

-"""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`

-#!/usr/bin/env python3
-"""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 \\

-
-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.

-        /api/v1/repos/{o}/{r}/actions/jobs/{id}   → HTTP 404
-        /api/v1/repos/{o}/{r}/actions/tasks/{id}  → HTTP 404

-    The SPA backend (`/{repo}/actions/runs/{id}/jobs/{idx}` POST) requires
-    a session CSRF token, unreachable from a runner. The only authoritative
-    source today is direct DB access (`mol_action_status` on op-host,
-    `docker exec molecule-postgres-1 psql ...`), which the runner cannot

-
-    Therefore: this hook returns None on every call. Callers MUST fall

-#!/usr/bin/env bash
-# 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
-#   DEFAULT_BRANCH=main — branch this gate protects; non-default-base PRs no-op

-"""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 and description == "Has been cancelled"
-             → compensate cancelled/superseded push noise.
-           - has_push_trigger=True otherwise → 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 ` (pull_request)` contexts unless the exact same
-    workflow/job has a successful ` (push)` context on the same
-    default-branch SHA. That case is post-merge status pollution, not
-    an unproven PR gate.
-  - 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`).
-
-Local dry-run (no network):
-    GITEA_TOKEN=... GITEA_HOST=git.moleculesai.app REPO=owner/repo \\
-      WATCH_BRANCH=main WORKFLOWS_DIR=.gitea/workflows \\

-endpoint the review-check.sh script calls.
-Reads $FIXTURE_STATE_DIR/token_owner_in_teams to decide whether
-the team membership probe returns 200/204 (member) or 403 (not in team).
-
-Scenarios:
-  T1_pr_open          — open PR, author=alice, sha=deadbeef → continue
-  T2_pr_closed        — closed PR → script exits 0 (no-op)
-  T3_reviews_approved_non_author  — one APPROVED from non-author → candidates exist
-  T4_reviews_empty             — zero APPROVED non-author → exit 1 (no candidates)
-  T5_reviews_only_author        — only author reviews → exit 1 (no candidates)
-  T6_reviews_dismissed          — dismissed APPROVED → treated as no approval
-  T7_team_member              — team membership → 204 (member) → exit 0
-  T8_team_not_member          — team membership → 404 (not a member) → exit 1
-  T9_team_403                — team membership → 403 (token not in team) → exit 1
-  T14_non_default_base        — open PR targeting staging → script exits 0 (no-op)
-  T15_comments_agent_approval — reviews empty; comments have "[core-qa-agent] APPROVED" → exit 0
-  T16_comments_generic_approval — reviews empty; comments have "APPROVED" by team member → exit 0
-  T17_comments_no_approval   — reviews empty; comments have no approval keywords → exit 1

-# SOP-Checklist gate — per-item required reviewer teams.
-#
-# RFC#351 v1 starter set. Each item lists:
-#   slug              — canonical kebab-case form used in /sop-ack <slug>
-#   pr_section_marker — substring matched in the PR body to detect that
-#                       the author filled in this item (case-insensitive)
-#   required_teams    — list of Gitea team names; an ack from ANY one of
-#                       these teams (logical OR) satisfies the item.
-#                       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.

-#   For tier:medium — hard-fail (same as high; medium is non-trivial).
-#   For tier:low — soft-fail (status `pending` with `acked: N/M` in the
-#                  description). BP can choose to require the context
-#                  or not for low-tier PRs.
-# If no tier label is present, default to medium (hard-fail) — every PR
-# should have a tier label per sop-tier-check, and absence indicates
-# a missing-tier defect we should surface, not silently lower the bar.

-#
-# A PR is "high-risk" when ANY of the listed labels are applied OR when

-# High-risk items use `required_teams_high_risk` (when present on the

-# This closes the inconsistency that the SOP charter already mandates

-# sop-checklist's `root-cause` and `no-backwards-compat` items now
-# follow the same risk-classed two-eyes shape:
-#   - Default class (tier:low/medium, not high-risk): a non-author
-#     engineers/managers/ceo ack satisfies the item — 25+ live
-#     identities, no dependency on a dead/inactive senior persona
-#     token.
-#   - High-risk class (tier:high OR any high_risk_label): still

-# ci-arm64-advisory — Mac arm64 self-hosted ADVISORY fast-check lane.
-#
-# === WHY ===
-#
-# The amd64 Gitea runner pool (molecule-runner-1..20) is queue-contended
-# (internal#418). This lane offloads the *genuinely container-independent*
-# fast checks (Go build/vet/lint, shellcheck, Python lint) onto the Mac
-# arm64 self-hosted runner so developers get a fast arm64 signal WITHOUT
-# adding load to the starved amd64 pool — capability-honestly, as an
-# additive pilot. Pilot ② of the Mac-CI strategy (CTO-delegated 2026-05-17).
-#
-# === NON-NEGOTIABLE SAFETY CONTRACT (the prime directive) ===
-#
-# This lane is **ADVISORY ONLY**. It is provably incapable of hanging a
-# merge. Concretely:
-#
-#   1. It is a SEPARATE workflow file. `ci.yml` is byte-for-byte
-#      untouched by this PR. The `CI / all-required` aggregator sentinel
-#      and the five contexts it polls
-#      (`CI / Detect changes|Platform (Go)|Canvas (Next.js)|
-#      Shellcheck (E2E scripts)|Python Lint & Test (pull_request)`)
-#      are unchanged. The canonical required gate stays 100% on the
-#      existing amd64 pool.
-#
-#   2. The context this workflow emits is
-#      `ci-arm64-advisory / fast-checks (pull_request)`. That string is
-#      DELIBERATELY NOT present in, and this PR does NOT add it to:
-#        - branch_protections/{main,staging}.status_check_contexts
-#          (DB-verified pb 86/75 = exactly
-#           ["CI / all-required (pull_request)",
-#            "sop-checklist / all-items-acked (pull_request)"])
-#        - audit-force-merge.yml REQUIRED_CHECKS env
-#        - ci.yml `all-required` sentinel's hardcoded `required[]` list
-#      Branch protection therefore never waits on this context. If the
-#      Mac runner is absent / offline / removed, this workflow's status
-#      simply never appears — and because nothing requires it, every
-#      merge proceeds exactly as it does today. There is no path by
-#      which a missing/red arm64 status blocks a merge.
-#
-#   3. `continue-on-error: true` on the job — even a genuine arm64-only
-#      failure (toolchain drift, arch-specific test flake) is surfaced
-#      as information, never as a merge blocker, for the duration of
-#      the pilot.
-#
-#   4. The job carries a `github.event_name` `if:` gate. Beyond its
-#      functional purpose this also keeps the job OUT of
-#      `ci-required-drift.py:ci_job_names()` (which excludes
-#      `github.event_name`/`github.ref`-gated jobs), so the hourly
-#      ci-required-drift sentinel's F1 ("job not under sentinel needs")
-#      cannot ever flag this advisory job. F2/F3 are untouched because
-#      this context is absent from BP and from REQUIRED_CHECKS.
-#      `lint-bp-context-emit-match` only fails on BP→emitter gaps; an
-#      emitter without a BP context is explicitly informational there.
-#
-# === RUNNER TARGETING ===
-#
-# The Mac runner is `hongming-pc-runner-1`. The bare `self-hosted`
-# label is POLLUTED in this Gitea instance: molecule-runner-1..20
-# (the contended amd64 pool) also advertise `self-hosted`. Targeting
-# bare `self-hosted` would route back onto the very pool we are trying
-# to relieve — and onto amd64 hardware. We therefore require an
-# AND-set of labels that ONLY the Mac satisfies. `macos-self-hosted`
-# is Mac-exclusive (the amd64 pool does not carry it). Until the
-# label-install burst (a10862b2) lands `self-hosted`+`macos-self-hosted`
-# on the Mac, the runner's current unique label `hongming-pc-laptop`
-# is also listed; AND-semantics over the labels a runner advertises
-# means a job requiring [self-hosted, macos-self-hosted] can ONLY be
-# claimed once the Mac advertises both. If neither label set is yet
-# present on the Mac, the workflow stays queued harmlessly and is
-# garbage-collected by the normal stale-run reaper — it blocks nothing
-# (see safety contract point 2).
-#
-# === ROLLBACK ===
-#
-# Delete this single file (`git rm .gitea/workflows/ci-arm64-advisory.yml`)
-# and merge. No branch-protection edit, no ci.yml edit, no
-# REQUIRED_CHECKS edit is required to roll back, because none were made
-# to roll forward. Zero blast radius either direction.

-# Comprehensive Playwright E2E for the unified chat stack (desktop
-# ChatTab + mobile MobileChat). Heavy browser execution is intentionally
-# outside the normal required PR path: PRs run it only after entering the
-# `merge-queue`, while push/main, nightly, and manual dispatch preserve
-# coverage without making every PR pay the full runtime/browser cost.
-#
-# Architecture:
-#   1. Ephemeral Postgres + Redis (docker, unique container names)
-#   2. workspace-server built from source, started with
-#      MOLECULE_ENV=development (fail-open auth)
-#   3. canvas dev server (npm run dev) on :3000
-#   4. Playwright tests create workspaces via API, point them at an
-#      in-process echo runtime, and exercise the full send/receive
-#      round-trip through the browser.
-#
-# Parallel-safety: same pattern as e2e-api.yml — per-run container names
-# and ephemeral host ports so concurrent jobs on the host-network runner
-# don't collide.

-
-# WHY A DEDICATED WORKFLOW (not folded into e2e-staging-saas.yml)
-# --------------------------------------------------------------
-# This is the systemic fix for a real trust failure. Hermes and OpenClaw
-# were reported "fleet-verified / cascade-complete" because the *proxy*
-# signals were green (registry registration + heartbeat for Hermes; model
-# round-trip 200 for OpenClaw). A freshly-provisioned workspace asked on
-# canvas "can you see your peers" actually FAILS:
-#   - Hermes: 401 on the molecule MCP `list_peers` call
-#   - OpenClaw: native `sessions_list` fallback, sees no platform peers
-# Tasks #142/#159 were even marked "completed" under this proxy flaw.
-#
-# A dedicated workflow (vs extending e2e-staging-saas.yml) because:
-#   - It must provision MULTIPLE distinct runtimes (hermes, openclaw,
-#     claude-code) in ONE org and assert each sees the others. The
-#     full-saas script is single-runtime-per-run (E2E_RUNTIME) and folding
-#     a multi-runtime matrix into it would conflate concerns and bloat its
-#     already-45-min run.
-#   - It needs its own concurrency group so it doesn't fight full-saas /
-#     canvas for the staging org-creation quota.
-#   - It needs an independent, non-required status-context name so it can
-#     be RED today (the in-flight Hermes-401 / OpenClaw-MCP-wiring fixes
-#     have not landed) WITHOUT wedging unrelated merges — and flipped to
-#     REQUIRED in one branch-protection edit once it goes green
-#     (flip-to-required checklist: molecule-core#1296).
-#
-# THE ASSERTION IS NOT A PROXY. The driving script
-# tests/e2e/test_peer_visibility_mcp_staging.sh issues the byte-for-byte
-# JSON-RPC `tools/call name=list_peers` envelope to `POST
-# /workspaces/:id/mcp` using each workspace's OWN bearer token, through
-# the real WorkspaceAuth + MCPRateLimiter middleware chain — the exact
-# call mcp_molecule_list_peers makes from a canvas agent. It does NOT
-# read a registry row, /health, the heartbeat table, or
-# GET /registry/:id/peers.
-#
-# HONEST GATE — NO continue-on-error. Per feedback_fix_root_not_symptom a
-# fake-green mask would defeat the entire purpose. This workflow goes red
-# on today's broken behavior and green only when the root-cause fixes
-# actually land. It is intentionally NOT in branch_protections — see PR
-# body for the required-vs-not decision + flip tracking issue.
-#
-# Gitea 1.22.6 / act_runner notes honored:
-#   - No cross-repo `uses:` (feedback_gitea_cross_repo_uses_blocked). The
-#     actions/checkout SHA is the one e2e-staging-canvas.yml already uses
-#     successfully (a mirrored SHA — see #1277/PR#1292 root-cause).
-#   - 2026-05-21 retrigger: verify fresh platform-tenant image after the
-#     publish Buildx DOCKER_CONFIG fix restored staging-latest image updates.
-#   - Per-SHA concurrency, not global (feedback_concurrency_group_per_sha).
-#   - Workflow-level GITHUB_SERVER_URL pinned
-#     (feedback_act_runner_github_server_url).
-#   - pr-validate posts a status under the same check name so a
-#     workflow-only PR is not silently statusless and the context is
-#     flip-to-required-ready (mirrors e2e-staging-saas.yml's proven shape;
-#     real EC2-provisioning E2E is push/dispatch/cron only — it is 30+ min
-#     and cannot run per-PR-update).
-#
-# LOCAL BACKEND (added 2026-05-15 — feedback_local_must_mimic_production,
-# feedback_mandatory_local_e2e_before_ship, feedback_local_test_before_
-# staging_e2e)
-# --------------------------------------------------------------------
-# The standing rule is that the local prod-mimic stack runs a MANDATORY
-# local-Postgres E2E BEFORE staging E2E. A staging-only peer-visibility
-# gate caught regressions late + expensively (cold EC2). The
-# `peer-visibility-local` job below runs the SAME byte-identical
-# assertion (tests/e2e/lib/peer_visibility_assert.sh) against the local
-# docker-compose stack — built + booted exactly like e2e-api.yml's
-# proven E2E API Smoke Test job (ephemeral pg/redis ports, go build,
-# background platform-server). It runs on PR + push (local boot is
-# minutes, not the 30+ min cold-EC2 path), so peer-visibility is part of
-# the local gate that fires before the staging E2E.
-#
-# It is its OWN non-required status context `E2E Peer Visibility (local)`.
-# The local backend uses external-mode workspaces by default so it tests
-# the literal platform MCP list_peers path without depending on local
-# template container boot/heartbeat. Container-mode runtime boot remains
-# available via PV_LOCAL_PROVISION_MODE=container for targeted debugging.

-# 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.
-# Mirrors `ci-required-drift.py`'s contract.
-#
-# Phase contract (RFC internal#219 §1 ladder)
-# -------------------------------------------
-# Lands at `continue-on-error: true` (Phase 3). After 7 days of clean
-# scheduled runs on `main`, flip to `false` so a scheduled failure

-# 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.
-# Tracking: mc#774.

-# 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.
-#
-# Cross-links
-# -----------
-# - mc#774 (the RFC that specs this lint)
-# - PR#665 / PR#668 (the empirical split-pair)
-# - mc#774 (the main-red incident the split caused)

-name: Lint no tenant GITEA or GITHUB token write
-
-# Task #146 — CI guardrail companion to RFC#523's `lint-forbidden-env-keys.yml`.
-#
-# `lint-forbidden-env-keys.yml` (Layer 3) catches code that hardcodes a
-# forbidden env-var key NAME as a quoted literal in workspace_secrets
-# writer paths under workspace-server/internal/.
-#
-# This workflow catches a BROADER class: any code path that reads a
-# repo-host token (GITEA_TOKEN / GITHUB_TOKEN / GH_TOKEN) and then writes
-# it into a TENANT WORKSPACE's env, secret store, user-data, or
-# provision payload. This is the actual RFC#523 threat-model statement —
-# the goal is "no tenant workspace ever receives an operator-scope repo
-# token," not just "no _quoted_ literal `GITEA_TOKEN`." A future writer
-# could route the value via a variable, a struct field, or a config key
-# and slip past the existing literal scan; this lint catches those
-# routing patterns at PR review time.
-#
-# Scope
-#   Scans the WHOLE repo's Go sources (not just workspace-server/) for
-#   co-occurrences of:
-#     - a repo-host token NAME (GITEA_TOKEN / GITHUB_TOKEN / GH_TOKEN /
-#       GITEA_PAT / GITHUB_PAT) used as os.Getenv argument or string
-#       literal
-#     - within a file that ALSO references a tenant-writer surface
-#       (`tenant`, `workspace_secrets`, `global_secrets`, `seedAllowList`,
-#       `/settings/secrets`, `userData`, `provisionPayload`,
-#       `envVars[`, `containerEnv`).
-#
-#   Co-occurrence (not single-line) is the false-positive control: a
-#   file that just LOGS the variable name (e.g. "missing GITEA_TOKEN")
-#   without touching any tenant surface won't fire.
-#
-# Drift contract with lint-forbidden-env-keys.yml
-#   Both lints share the same FORBIDDEN_KEYS list (a subset — only the
-#   repo-host tokens, since this lint's threat model is "tenant gets
-#   write access to operator's git host"). If RFC#523's deny set grows,
-#   update BOTH this file AND lint-forbidden-env-keys.yml AND the Go
-#   source-of-truth in
-#   workspace-server/internal/handlers/workspace_provision_forbidden_env.go.
-#
-# Open-source-template-friendly
-#   The patterns scanned are generic (no MOLECULE_-prefix literals).
-#   A fork can copy this workflow as-is and adjust FORBIDDEN_KEYS.
-#
-# Path-filter discipline
-#   No `paths:` filter — required-status workflows must run on every PR
-#   per `feedback_path_filtered_workflow_cant_be_required`. Scan is

-name: Lint pre-flip continue-on-error
-
-# Pre-merge gate: blocks PRs that flip `continue-on-error: true → false`
-# 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.
-#

-# Tier 2g hard-gate lint (per mc#774) — diff-based PR-time
-# 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
-#   - `# bp-required: pending #NNN`  — acknowledged asymmetry + tracker
-#   - `# bp-exempt: <reason>`        — informational job, not a gate
-#
-# 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
-# the author added a `bp-required: pending` directive.
-#
-# 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
-# emitter so both PR-time (Tier 2g) and post-merge (Tier 2f)
-# readers consume the same source.
-#
-# Phase contract (RFC internal#219 §1 ladder)
-# -------------------------------------------
-# Lands at `continue-on-error: true` (Phase 3 — surface the
-# pattern without blocking PRs while the directive convention
-# beds in). After 7 days of clean runs on `main` with no false
-# positives, follow-up flips to `false`. Tracking: mc#774.

-# Fails the PR if ANY workflow whose status-check context appears in
-# `branch_protections/main.status_check_contexts` carries a
-# `paths:` or `paths-ignore:` filter in its `on:` block.
-#
-# Why this exists:
-#   A required-check workflow with a paths filter silently degrades the
-#   merge gate. If a PR's diff doesn't touch the filter, the workflow
-#   never fires; Gitea (1.22.6) reports the required context as
-#   `pending` (NOT `skipped == success`), so the PR cannot merge. For a
-#   docs-only PR against `paths: ['**.go']`, the PR is wedged forever.
-#
-#   Previously prevented only by reviewer vigilance + the saved memory
-#   `feedback_path_filtered_workflow_cant_be_required`. This workflow
-#   makes it a hard CI gate.
-#
-# Forward-compat scope:
-#   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

-#
-# IMPORTANT — Gitea 1.22.6 parser quirk per

+# 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.

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

+# Why two workflows: the chicken-and-egg #128 fix added a "PR-built

-# sop-checklist — peer-ack merge gate for SOP-checklist items.
-#
-# RFC#351 Step 2 of 6 (implementation MVP).
-#
-# === CONSOLIDATION (issue #1280) ===
-#
-# This workflow is the SINGLE `issue_comment` subscriber — the logic from
-# `review-refire-comments.yml` has been merged in. Before this change:
-#   - sop-checklist.yml (pre-2026-05-16) → issue_comment:[created,edited,deleted] → runner slot used, job no-oped
-#   - review-refire-comments.yml           → issue_comment:[created]            → runner slot used, job no-oped
-#   → every non-refire comment occupied 2 runner slots for ~800 s each
-#      (~650 no-op runs/day, ~1,300 runner-slot-occupancy-hours/day).
-#
-# Fix (PR #1345 / issue #1280):
-#   - ONE workflow, ONE issue_comment:[created] subscription (no edited/deleted)
-#   - all-items-acked job: pull_request_target OR sop slash-command comments
-#   - review-refire job: qa/security/tier refire slash commands
-#   → ~50% reduction in comment-triggered runner occupancy vs pre-fix.
-#
-# 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)

-# status-reaper — Option B (compensating-status POST) for Gitea 1.22.6's
-# hardcoded `(push)` suffix on default-branch commit statuses.
-#
-# Tracking: molecule-core#? (this PR), internal#327 (sibling publish-runtime-bot),
-# internal#328 (sibling mc-drift-bot), internal#80 (upstream RFC). Sister
-# bots already deployed under the same per-persona-identity contract
-# (`feedback_per_agent_gitea_identity_default`).
-#
-# Root cause:
-#   Gitea 1.22.6 emits commit-status context as
-#     `<workflow_name> / <job_name> (push)`
-#   for ANY workflow run on the default branch's HEAD commit, REGARDLESS
-#   of the trigger event. Schedule- and workflow_dispatch-triggered runs
-#   on `main` therefore appear as `(push)` failures on the latest main
-#   commit, painting main red via a fake-push status. Verified on runs
-#   14525 + 14526 via Phase 1 evidence (3 sub-agents). No upstream fix
-#   in 1.23-1.26.1 (sibling a6f20db1 research).
-#
-# Why a cron-driven reaper, not workflow_run:
-#   Gitea 1.22.6 does NOT support `on: workflow_run` (verified via
-#   modules/actions/workflows.go enumeration; sister a6f20db1). The
-#   only event-shaped option that fires is cron. 5min is chosen to
-#   sit BETWEEN ci-required-drift (`:17` hourly) and main-red-watchdog
-#   (`:05` hourly) so the reaper sweeps red before the watchdog files
-#   a `[main-red]` issue (would-be false-positive).
-#
-# What the reaper does each tick:
-#   1. Parse `.gitea/workflows/*.yml`, classify each by whether `on:`
-#      contains a `push:` trigger (see script for workflow_id resolution
-#      including `name:` collision and `/`-in-name fail-loud lints).
-#   2. GET combined status for main HEAD.
-#   3. For each `failure` status whose context ends ` (push)`:
-#      - if workflow has push trigger: PRESERVE (real defect signal).
-#      - if workflow has no push trigger: POST a compensating
-#        `state=success` with the same context and a description that
-#        documents the workaround.
-#
-# What it does NOT do:
-#   - Mutate non-`(push)`-suffix statuses (e.g. `(pull_request)` from
-#     branch_protections required-checks — verified safe 2026-05-11).
-#   - Auto-revert. Same reasoning as main-red-watchdog.
-#   - Cancel runs. The runs themselves stay visible in Actions UI; the
-#     fix is at the commit-status surface only.
-#
-# Removal path: drop this workflow when Gitea ≥ 1.24 ships with a
-# real fix for the hardcoded-suffix bug. Audit issue (filed post-merge)
-# tracks the deletion as a follow-up sweep.

+# 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.
+#
+# 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 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-
+#     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 CANARY_TENANT_URLS / CANARY_ADMIN_TOKENS /
+#     CANARY_CP_SHARED_SECRET are populated.

+# 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 API Smoke Test
+# Extracted from ci.yml so workflow-level concurrency can protect this job
+# from run-level cancellation (issue #458).
+#
+# 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.

+# 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.
