+# 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 "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

+# MEMBER/OWNER/COLLABORATOR comments `/refire-tier-check` on a PR.

+#
+# 1. Resolve PR head SHA + author from PR_NUMBER.
+# 2. Rate-limit: if the sop-tier-check context has been POSTed in the

+# 3. Invoke `.gitea/scripts/sop-tier-check.sh` with the same env the
+#    canonical workflow provides. This is DRY: we re-use the exact AND-
+#    composition gate logic, not a watered-down approving-count check.
+# 4. POST the resulting status (success on exit 0, failure on non-zero)
+#    to `/repos/.../statuses/{HEAD_SHA}` with context
+#    "sop-tier-check / tier-check (pull_request)" — the same context name
+#    branch protection requires.

-"""Live-fire regression test for #2159 — gate auto-fire runtime verification.
-
-Static tests (test_gate_review_auto_fire.py) validate that the workflow YAML
-is structurally correct. This test validates the *runtime* path: submitting an
-APPROVED review to a PR whose head contains the current gate workflows causes
-Gitea Actions to queue the qa-review + security-review workflows and POST the
-branch-protection-required (pull_request_target) contexts within a reasonable
-window.
-
-Skipped when Gitea API credentials are not available. Intended for:
-  - manual developer verification
-  - CI jobs provisioned with a service-account token
-
-Environment:
-  GITEA_HOST            — default: git.moleculesai.app
-  GITEA_TOKEN           — token with read:repository + write:issues (for review POST)
-  REPO                  — default: molecule-ai/molecule-core
-  LIVEFIRE_PR_NUMBER    — optional; if omitted the test tries to find a
-                          suitable open PR automatically, or skips.

+# Regression test for #229 — sop-tier-check tier:low OR-clause splitter.
+#
+# 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

-"""umbrella-reaper — auto-recovery for stale CI umbrella statuses on PRs.
-
-Tracking: molecule-core#1780.
-
-Sibling to status-reaper.py (default-branch push-suffix compensation),
-but scoped to pull_request umbrellas instead of main-branch contexts.
-
-What this script does, per `.gitea/workflows/umbrella-reaper.yml` invocation:
-
-  1. List open PRs via GET /repos/{o}/{r}/pulls?state=open&limit={N}.
-  2. For EACH PR:
-     - GET combined commit status for PR head SHA.
-     - Look for the umbrella context (default: "CI / all-required (pull_request)").
-     - If umbrella state is "failure":
-         - Verify ALL required sub-job contexts are "success".
-         - If yes → POST compensating success to /statuses/{sha} with the
-           same umbrella context and an honest description.
-         - If any required sub-job is NOT success → skip (umbrella correctly
-           reflects reality; do NOT lie).
-     - If umbrella state is "success" or "pending" → skip.
-  3. Exit 0. Re-running is idempotent — Gitea de-dups by context.
-
-What it does NOT do:
-  - Touch non-umbrella contexts.
-  - Compensate when ANY required sub-job is missing, pending, failure, or
-    cancelled. Only the "all sub-jobs green, umbrella stale" race.
-  - Merge PRs. It only posts a status; branch protection still requires
-    human approval.
-  - Run on closed PRs.
-
-Halt conditions:
-  - Missing required env vars → exit 1 with ::error:: message.
-  - API 5xx on PR list → fail-loud (can't assess state).
-  - API 5xx on an individual PR's status → ::warning:: + continue to next PR.

-          This canvas-touching main push triggers `publish-canvas-image`, which now
-          runs an ORDERED, CI-gated deploy (core#2226) — the same shape as the
-          platform's deploy-production:
+          The `publish-canvas-image` workflow is now building a fresh Docker image
+          (`ghcr.io/molecule-ai/canvas:latest`) in the background.

-          1. Build → push `molecule-ai/canvas:staging-<sha>` + `:staging-latest`.
-          2. Wait for green main CI on this SHA.
-          3. Promote `:latest` to the verified `:staging-<sha>` by digest.
+          Once it completes (~3–5 min), apply on the host machine with:
+          ```bash
+          cd <runner-workspace>
+          git pull origin main
+          docker compose pull canvas && docker compose up -d canvas
+          ```

-          Tenants/hosts pin via `CANVAS_IMAGE_TAG` (default `latest` = the last
-          CI-green build), so a deploy is reproducible — no hand-run
-          `docker compose pull` needed. Watch the run in the canvas publish workflow.
+          If you need to rebuild from local source instead (e.g. testing unreleased
+          changes or a new `NEXT_PUBLIC_*` URL), use:

-  #
-  # The REAL-boot complement to the deterministic unit suite
-  # (workspace_provision_platform_boot_test.go). Provisions a REAL staging
-  # claude-code workspace on the PLATFORM-managed path — provider=platform,
-  # model=moonshot/kimi-k2.6, NO tenant LLM key — and asserts it reaches
-  # status=online (NOT not_configured) and a completion returns 200, via the same
-  # online-wait + completion-assert the BYOK job uses.
-  #
-  # Why a SEPARATE job (not a matrix leg of e2e-staging-saas): the platform path
-  # injects NO secret and pins a different model, so its env block diverges from
-  # the BYOK job's. A dedicated job keeps each path's "verify key present" preflight
-  # honest (BYOK requires a key; platform requires its ABSENCE not to matter) and
-  # gives the regression its own named commit-status for branch protection.
-  #
-  # Add `E2E Staging Platform Boot` to branch protection after 3 consecutive
-  # green runs on main (de-flake window; this path shares the cp#245
-  # boot-timeout flake surface the BYOK job has, so it must prove stable before

-# container. This drives the Go staginge2e suite
-# (workspace-server/internal/staginge2e/workspace_lifecycle_test.go) which

-# ADVISORY-BY-INFRA. It needs a live staging tenant (~30+ min cold EC2 path), so
-# the real run is workflow_dispatch / schedule only — NOT per-PR and NOT a
-# required check. Promotion to a required branch-protection context is a separate
-# CTO decision (mirrors the cp internal/staginge2e suite, cp#386, and the

+# sop-tier-refire — manual fallback for sop-tier-check refire.
+#
+# 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`).
+#
+# Comment-triggered refires now live in `review-refire-comments.yml`. Gitea
+# queues issue_comment workflows before evaluating job-level `if:`, so having
+# qa-review, security-review, sop-checklist, and sop-tier-refire all subscribe
+# to every comment caused queue storms on SOP-heavy PRs. This workflow is a
+# non-automatic breadcrumb only; Gitea 1.22.6 does not support
+# workflow_dispatch inputs, so real refires must use `/refire-tier-check`.
+#
+# 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"
+# guard prevents comment-spam from thrashing the status. See the script.

-/**
- * Staging canvas E2E — desktop take-control RECONNECT + LEASE-RENEWAL path
- * (core#2332 "P0.7", the e2e gap left by core#2216).
- *
- * Sibling to staging-display.spec.ts. That spec proves the happy path
- * (acquire → noVNC WS upgrade → first framebuffer frame). It does NOT cover
- * the two behaviours core#2216 added on top of that happy path:
- *
- *   (A) RECONNECT re-acquires a FRESH token. When the live WS drops uncleanly
- *       (idle/network blip), DisplayTab.tsx:391-446 calls connect(reacquire=true),
- *       which first awaits reacquireSession() (DisplayTab.tsx:83-99 →
- *       POST /display/control/acquire) to mint a NON-stale lease+token before
- *       reopening the socket. Without this, the cached ~300s token can be past
- *       its expiry and the reconnect would 401 — a dead session that LOOKS like
- *       a reconnect. We assert the reconnect path yields a token bound to a NEW
- *       expires_at AND that a NEW WS opened with that fresh token resumes the
- *       framebuffer (a real frame, not a 1006/403).
- *
- *   (B) The lease SURVIVES past the 300s window via the renewal cadence.
- *       The lock is a 300s lease with NO server-side auto-renewal
- *       (workspace_display_control.go:27 displayControlDefaultTTLSeconds=300;
- *       loadActiveDisplayControl filters `expires_at > now()`). DisplayTab.tsx:105-111
- *       runs a 120_000ms setInterval that re-acquires as the same holder, which
- *       the server's ON-CONFLICT upsert (workspace_display_control.go:116-123,
- *       `controlled_by = EXCLUDED.controlled_by`) treats as a lease EXTENSION:
- *       expires_at moves forward by a fresh 300s each renewal. We do NOT sleep
- *       300s of wall-clock to prove this — we drive the renewal CALL the timer
- *       fires (reacquireSession === the same POST) and assert it pushes
- *       expires_at strictly past the ORIGINAL lease window, then confirm the
- *       lock is still live (GET /display/control returns the holder) after a
- *       point in time at which the original, un-renewed lease would already be
- *       expired. That is the observable, deterministic proxy for "the 120s
- *       timer keeps the user from being kicked every ~5 min."
- *
- * Auth model, gating, and fail-closed philosophy are IDENTICAL to
- * staging-display.spec.ts — see that file's header for the full rationale
- * (same-origin-canvas Origin for the WS upgrade; per-tenant admin bearer for
- * the acquire/GET POSTs; STAGING_DISPLAY_WORKSPACE_ID is the single activation
- * knob and a standing desktop EC2 is a CTO cost item; any failure once the gate
- * env is present is a HARD error, never a silent green, no "flaky" disposition).
- *
- * Promote-to-required is a CTO call: like its sibling this only runs when a
- * standing desktop-capable staging workspace exists, so it cannot be a blanket
- * required context until that workspace is funded and STAGING_DISPLAY_* is wired
- * into the e2e-staging-canvas workflow.

-/**
- * Staging canvas E2E — REAL desktop take-control path (core#2261 "Gap 1").
- *
- * This is the live-e2e gate that the existing staging-tabs.spec.ts does NOT
- * provide. staging-tabs only opens the 13 declared workspace-panel tabs
- * (TAB_IDS at staging-tabs.spec.ts:24-38 — `display` is NOT among them) and
- * asserts they render without a "Failed to load" toast. It never acquires
- * display control, never opens the noVNC WebSocket, and never asserts a
- * framebuffer frame arrives. The companion unit test
- * canvas/src/components/tabs/__tests__/DisplayTab.test.tsx mocks the RFB
- * constructor (vi.mock("@novnc/novnc"), see its lines 8/20-39) so NO real
- * WebSocket is ever opened there either. Result: a broken take-control path
- * (acquire → noVNC WS upgrade → ws-proxy → EIC → websockify → x11vnc → Xvfb)
- * ships GREEN. This spec closes that gap by exercising the REAL wire path
- * end to end against a live, desktop-capable staging workspace.
- *
- * What it asserts (the real path, no mocks):
- *   1. POST /workspaces/<id>/display/control/acquire returns 200 with a
- *      session_url that carries the signed token in its `#token=` fragment
- *      (mirrors workspace_display_control.go:signedDisplaySessionURL).
- *   2. Opening the noVNC WebSocket at session_url with the subprotocols
- *      ["binary", "molecule-display-token.<token>"] (exactly what the canvas
- *      sends — DisplayTab.tsx:339) UPGRADES (onopen fires, readyState===OPEN,
- *      no immediate 1006 abnormal close). A 1006 / 403 means the handshake
- *      failed somewhere in the proxy chain.
- *   3. At least one BINARY framebuffer message arrives on that socket — a
- *      real frame off x11vnc, not just a panel mount. RFB sends a
- *      ProtocolVersion banner ("RFB 003.00x\n") as the first server message,
- *      which proves the upstream VNC server is live behind the EIC tunnel.
- *
- * Auth model (important): the WS upgrade is gated by workspace-server
- * middleware.AdminAuth. A browser WebSocket CANNOT set an Authorization
- * header, so in production the canvas WS upgrade passes AdminAuth via the
- * same-origin-canvas path (wsauth_middleware.go:isSameOriginCanvas, which
- * keys off the Origin header the browser sets automatically on a same-origin
- * WS upgrade). We therefore open the socket from inside the browser page via
- * page.evaluate AFTER navigating to the tenant origin — so the browser sends
- * `Origin: https://<slug>.staging.moleculesai.app`, exactly as production
- * does. The acquire POST (which CAN carry a header) uses the per-tenant admin
- * bearer set on the context. This is the faithful production handshake, not a
- * synthetic one.
- *
- * Gate / cost: this test only runs when STAGING_DISPLAY_WORKSPACE_ID points
- * at a STANDING desktop-capable workspace (compute.display.mode ==
- * "desktop-control"). We deliberately do NOT provision one in the shared
- * staging-setup.ts: a desktop AMI boots in ~12-15 min and would tax the
- * existing tabs harness on every run. Standing that workspace up is a cost
- * item for the CTO (one always-on desktop EC2 on staging). Until that exists,
- * the test SKIPS loud. When the env IS present, any failure in
- * provision/acquire/upgrade is a HARD error — fail-closed, never silently
- * green (no "flaky" disposition: a 1006 names a broken proxy hop).

- *     both other error phrasings and role-less error divs).

- * STILL BLOCKS PROMOTION-TO-REQUIRED (do NOT flip continue-on-error here —
- * CTO-owned, RFC internal#219 §1):
- *   - INFRA DEPENDENCY: each run provisions a real staging EC2 tenant
- *     (12-20 min cold boot). Required-gate latency + AWS/Cloudflare/CP
- *     availability become merge-blockers. A staging outage would freeze
- *     main even though the code is fine — unacceptable for a required check
- *     until staging has an SLA or this runs against a warm pre-provisioned
- *     pool.
- *   - SHARED-RESOURCE FLAKE SURFACE: TLS/DNS/ACME propagation on a shared
- *     staging zone (staging-setup TLS_TIMEOUT_MS) is outside this repo's
- *     control. Deterministic here ≠ deterministic upstream.
- *   - SECRET DEPENDENCY: CP_STAGING_ADMIN_API_TOKEN must be present on the
- *     runner. The workflow's skip-if-absent (core#2225) keeps a missing
- *     secret from painting red — correct for non-gating, but a REQUIRED
- *     check must instead guarantee the secret is always present, else it
- *     skip-greens the very thing it is supposed to enforce.
- *   - SINGLE-WORKSPACE COVERAGE: one hermes/platform_managed workspace that
- *     does NOT boot an agent on staging (no CP LLM proxy env, workspace-
- *     server #2162). Tabs render, but agent-dependent content paths (live
- *     chat round-trip, traces from a real run) are not exercised.
- *
- * PROMOTION CHECKLIST (when CTO signs off on making this required):
- *   1. Warm pre-provisioned tenant pool OR a staging SLA bounding boot time.
- *   2. Guarantee CP_STAGING_ADMIN_API_TOKEN on the gating runner; turn the
- *      skip-if-absent into a hard error for the required path.
- *   3. Decide whether agent-dependent tabs need a wired LLM proxy on the
- *      staging tenant (covers chat/traces real content) before gating them.
