test(tabs): add BudgetSection coverage (17 cases)

Covers all render states: loading, fetch error, 402 exceeded banner,
budget loaded (with/without limit, over-limit cap), progress bar
visibility, save success, save error, saving-in-flight button state,
and the isApiError402 helper's regex branches.

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

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

+# review-check — evaluate whether a PR satisfies a single team-review gate.
+#
+# RFC#324 Step 1 of 5 — qa-review + security-review check workflows.
+#
+# This is the shared evaluator invoked by:
+#   .gitea/workflows/qa-review.yml      (TEAM=qa,      TEAM_ID=20)
+#   .gitea/workflows/security-review.yml (TEAM=security, TEAM_ID=21)
+#
+# Pass condition (per RFC#324 v1.1 addendum):
+#   ≥ 1 review on the PR where:
+#     • state == APPROVED
+#     • review.dismissed == false
+#     • review.user.login != PR.user.login (non-author)
+#     • review.user.login ∈ team-members
+#
+# Strict mode (default OFF for v1; see RFC trade-off note):
+#   If REVIEW_CHECK_STRICT=1, additionally require review.commit_id == PR.head.sha.
+#   With dismiss_stale_reviews: true at the protection layer, stale reviews
+#   are already dismissed, so the additional commit_id check is belt-and-
+#   suspenders. Keeping it off in v1 simplifies semantics; flip in a follow-up
+#   PR if reviewer telemetry shows residual stale-APPROVE merges.
+#
+# Privilege gate (RFC#324 v1.3 §A1.1 — INFORMATIONAL ONLY):
+#   The /qa-recheck and /security-recheck slash-commands can be triggered
+#   by anyone who can comment on the PR. The workflow's privilege step
+#   logs collaborator-status but does NOT gate execution of this script.
+#   Why this is safe: this evaluator is read-only and idempotent —
+#   reading `pulls/{N}/reviews` and `teams/{id}/members/{u}` can't be
+#   influenced by who triggered the run. If a real team-member APPROVE
+#   exists the gate flips green; otherwise it stays red. A
+#   non-collaborator commenting /qa-recheck cannot manufacture a green
+#   gate. Original (v1.2) design with `if:`-gating of this step was
+#   fail-open (skipped-via-`if:` job still publishes the status as
+#   `success`) — corrected in v1.3 per hongming-pc review 1421.
+#
+# Trust boundary (RFC A4):
+#   This script is loaded from the BASE branch (sourced via .gitea/scripts/
+#   on the workflow's checkout-of-base). It does NOT execute any PR-HEAD
+#   code. It only reads PR review state via the Gitea API.
+#
+# Token scope (RFC A1-α):
+#   The job's own conclusion (exit 0 / exit 1) is what publishes the
+#   `qa-review / approved` / `security-review / approved` status context.
+#   NO `POST /statuses` call here → NO `write:repository` scope on the
+#   token. `read:organization` (for team-membership probe) and
+#   `read:repository` (for PR + reviews) are enough.
+#
+# Required env:
+#   GITEA_TOKEN — least-priv read:repository + read:organization. See note
+#                 below about the team-membership API requiring the token
+#                 owner to be in the queried team (Gitea 1.22.6 quirk).
+#   GITEA_HOST  — e.g. git.moleculesai.app
+#   REPO        — owner/name (from github.repository)
+#   PR_NUMBER   — int (from github.event.pull_request.number or
+#                 github.event.issue.number for issue_comment events)
+#   TEAM        — short team name (qa | security) for log lines

+"""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. GET combined status for HEAD of WATCH_BRANCH.
+
+  3. For each per-context status entry where:
+       state == "failure" AND context.endswith(" (push)")
+     Parse context as `<workflow_name> / <job_name> (push)`. Look up
+     workflow_name in the trigger map:
+       - missing → log ::notice:: and skip (conservative).
+       - has_push_trigger=True → preserve (would mask real 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 that
+         documents the workaround + this script's path.
+
+  4. Exit 0. Re-running is idempotent — Gitea's commit-status table
+     stores the LATEST state-per-context, so the success POST sticks
+     even if another tick happens before the runner finishes.
+
+What it does NOT do:
+  - Touch any context NOT ending in ` (push)`. The required-checks on
+    main (verified 2026-05-11) all have ` (pull_request)` suffixes;
+    they CANNOT be reached by this code path.
+  - Compensate `error`/`pending` states. Only `failure` — the only one
+    Gitea emits for the hardcoded-suffix bug.
+  - Write to non-default branches. WATCH_BRANCH is sourced from
+    `github.event.repository.default_branch` in the workflow.
+  - Mutate workflows or runs. The Actions UI still shows the
+    underlying schedule-triggered run as failed; this script edits
+    the commit-status surface only.
+
+Halt conditions (script-level — orchestrator-level halts are in the
+workflow comments):
+  - PyYAML missing → fail-loud at import (no fallback parse).
+  - Workflow `name:` collision → exit 1 with ::error:: message.
+  - Workflow `name:` containing `/` → exit 1 with ::error:: message.
+  - Ambiguous `on:` shape (e.g. neither str/list/dict) → treat as
+    "has_push_trigger=True" and log ::notice:: (preserve, never
+    compensate the unknown).
+  - api() non-2xx → raise ApiError, fail the workflow run loudly so
+    a subsequent tick retries (per
+    `feedback_api_helper_must_raise_not_return_dict`).

+    #     status_check_contexts will reference only `ci/all-required` (Step 5
+    #     follow-up — branch-protection PATCH is Owners-tier per

+    # Excluded from `needs:`: `canvas-deploy-reminder` — gated by

+    # explicitly excludes `github.event_name`-gated jobs from F1 (see
+    # `.gitea/scripts/ci-required-drift.py::ci_job_names`).
+    #
+    # Phase 3 (RFC #219 §1) safety: continue-on-error here so the sentinel
+    # does not hard-fail and block PRs while the underlying build jobs are
+    # still in Phase 3 (continue-on-error: true suppresses their status to null).

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

+  # minimal until that's actually wanted.
+
+# Serialize so two firings can never overlap. Cron firing every 20 min

+# 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

+#   - Needs its own concurrency group so two pushes don't fight over the
+#     same staging org slug prefix.
+#   - Has its own required secrets (session cookie, admin token) that most
+#     PRs don't need to read.
+#
+# Triggers:
+#   - Push to main (regression guard — fires on merges to main, not on PR updates)
+#   - pull_request: pr-validate always posts success; real E2E step runs only
+#     when provisioning-critical files change (detect-changes gates the step).
+#   - workflow_dispatch (manual re-run from UI)
+#   - Nightly cron (catches drift even when no pushes land)
+#
+# NOTE: A separate pr-validate job handles the pull_request path so this
+# workflow posts CI status for workflow-only PRs. Without it, a PR that
+# only touches the workflow file has no status check (workflow only fires
+# on push, not PR branches), which blocks merge under branch protection.
+# The E2E step itself only runs when provisioning-critical files change —
+# pr-validate always posts success, avoiding the double-fire that motivated
+# the pull_request-trigger removal in PRs #516/#530.

+# Ported from .github/workflows/handlers-postgres-integration.yml on 2026-05-11 per RFC

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

+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#
+
+# Real-Postgres integration tests for workspace-server/internal/handlers/.
+# Triggered on every PR/push that touches the handlers package.
+#
+# Why this workflow exists
+# ------------------------
+# Strict-sqlmock unit tests pin which SQL statements fire — they're fast
+# and let us iterate without a DB. But sqlmock CANNOT detect bugs that
+# depend on the row state AFTER the SQL runs. The result_preview-lost
+# bug shipped to staging in PR #2854 because every unit test was
+# satisfied with "an UPDATE statement fired" — none verified the row's
+# preview field actually landed. The local-postgres E2E that retrofit
+# self-review caught it took 2 minutes to set up and would have caught
+# the bug at PR-time.
+#
+# Why this workflow does NOT use `services: postgres:` (Class B fix)
+# ------------------------------------------------------------------
+# Our act_runner config has `container.network: host` (operator host
+# /opt/molecule/runners/config.yaml), which act_runner applies to BOTH
+# the job container AND every service container. With host-net, two
+# concurrent runs of this workflow both try to bind 0.0.0.0:5432 — the
+# second postgres FATALs with `could not create any TCP/IP sockets:
+# Address in use`, and Docker auto-removes it (act_runner sets
+# AutoRemove:true on service containers). By the time the migrations
+# step runs `psql`, the postgres container is gone, hence
+# `Connection refused` then `failed to remove container: No such
+# container` at cleanup time.
+#
+# Per-job `container.network` override is silently ignored by
+# act_runner — `--network and --net in the options will be ignored.`
+# appears in the runner log. Documented constraint.
+#
+# So we sidestep `services:` entirely. The job container still uses
+# host-net (inherited from runner config; required for cache server
+# discovery on the bridge IP 172.18.0.17:42631). We launch a sibling
+# postgres on the existing `molecule-core-net` bridge with a
+# UNIQUE name per run — `pg-handlers-${RUN_ID}-${RUN_ATTEMPT}` — and
+# read its bridge IP via `docker inspect`. A host-net job container
+# can reach a bridge-net container directly via the bridge IP (verified
+# manually on operator host 2026-05-08).
+#
+# Trade-offs vs. the original `services:` shape:
+#   + No host-port collision; N parallel runs share the bridge cleanly
+#   + `if: always()` cleanup runs even on test-step failure
+#   - One more step in the workflow (+~3 lines)
+#   - Requires `molecule-core-net` to exist on the operator host
+#     (it does; declared in docker-compose.yml + docker-compose.infra.yml)
+#
+# Class B Hongming-owned CICD red sweep, 2026-05-08.

+# Why this exists: 2026-04-30 we shipped #2398 which added /buildinfo as

+# 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.

+#
+# RFC#324 Step 1 of 5 (workflow-add). Pairs with `security-review.yml` and the
+# branch-protection flip in Step 2.
+#
+# === DESIGN (RFC#324 v1.1 addendum) ===
+#
+# A1-α (refire mechanism):
+#   Triggers on:
+#     - `pull_request_target`: opened, synchronize, reopened
+#         → initial status posts when PR opens / re-pushes
+#     - `issue_comment`: /qa-recheck slash-command on the PR
+#         → manual re-fire after a QA reviewer clicks APPROVE
+#           (Gitea 1.22.6 doesn't re-fire on pull_request_review, per
+#           go-gitea/gitea#33700 + feedback_pull_request_review_no_refire)
+#   Workflow name = `qa-review` ; job name = `approved`.
+#   The job's own pass/fail conclusion publishes the status context
+#   `qa-review / approved (<event>)` — NO `POST /statuses` call → NO
+#   write:repository token scope needed. Sidesteps internal#321 defect #2.
+#
+# A1.1 (privilege check on slash-comment — INFORMATIONAL ONLY, NOT a gate):
+#   The `issue_comment` event fires for ANY commenter, including
+#   non-collaborators. The original (v1.2) design gated the eval step
+#   behind a collaborator probe → if a non-collaborator commented
+#   /qa-recheck, the eval was `if:`-skipped → the job exited 0 anyway →
+#   the status context published `success` with ZERO real APPROVE.
+#   That was a fail-open: any visitor could green the gate.
+#
+#   RFC#324 v1.3 §A1.1 correction (option b per hongming-pc 1421):
+#   drop privilege-gating of the evaluation entirely. The eval is
+#   read-only and idempotent — it reads `pulls/{N}/reviews` and
+#   `teams/{id}/members/{u}` (both API-side state that a commenter can't
+#   change). Re-running it on a non-collaborator's comment is harmless
+#   AND correct: if a real team-member APPROVE exists, the eval flips
+#   green; if not, it stays red.
+#
+#   We KEEP the privilege step as a `::notice::` log line only — useful
+#   for griefer-spotting (one operator spamming /recheck) without
+#   touching the gate. If rate-limiting is needed later, add it as a
+#   separate concern (time-window throttle, not a privilege gate).
+#
+#   We MUST NOT use `github.event.comment.author_association` (the
+#   field doesn't exist on Gitea 1.22.6 webhook payload — this was
+#   sop-tier-refire's defect #1).
+#
+# A4 (no PR-head checkout under pull_request_target):
+#   We check out the BASE ref explicitly so the review-check.sh script is
+#   loaded from trusted source. We NEVER use `ref: ${{ github.event.pull_request.head.sha }}`.
+#   No PR-head code is executed in the runner. Trust boundary preserved.
+#
+# A5 (real Gitea team):
+#   `qa` team (id=20) verified by orchestrator preflight 2026-05-11; queried
+#   at run time via /api/v1/teams/20/members/{login}.
+#
+# === TOKEN ===
+#
+# The workflow reads PR state, PR reviews, and team membership.
+# Gitea 1.22.6's /api/v1/teams/{id}/members/{u} returns 403 ('Must be a
+# team member') for tokens whose owner is not in that team. The default
+# `secrets.GITHUB_TOKEN` is owned by a workflow-scoped identity that is
+# also not in qa/security teams → also 403.
+#
+# Resolution: a dedicated `RFC_324_TEAM_READ_TOKEN` secret, owned by an
+# identity that IS in both `qa` and `security` teams (Owners-tier
+# claude-ceo-assistant, or a new service-bot added to both teams).
+# Provisioning of this secret is tracked as a follow-up issue (filed by
+# core-devops at PR open).
+#
+# Until that secret is provisioned, the job will exit 1 with a clear
+# 403-on-team-probe error and the `qa-review / approved` status will
+# stay `failure`. This is the correct fail-closed behavior — the gate
+# blocks merge until both (a) a QA team member APPROVEs and (b) the
+# workflow has a token that can confirm their team membership.
+#
+# === SLASH-COMMAND CONTRACT ===
+#
+#   /qa-recheck   — re-evaluate the gate (e.g. after an APPROVE lands)
+#
+# Open to any PR commenter. The eval is read-only and idempotent, so
+# unprivileged refires are harmless (RFC#324 v1.3 §A1.1). Collaborator

+#     Manual runs go via cron-trigger bump or push the workflow file
+#     itself.
+#   - `actions/github-script@v9` blocks (which call github.rest.* — a

+#     Gitea REST API (/api/v1/repos/.../issues, .../labels,
+#     .../comments). Same behaviour: open issue on drift, comment on
+#     repeat-drift, close on clean run.
+#   - Workflow-level env.GITHUB_SERVER_URL set so the curl calls can
+#     derive `git.moleculesai.app` from the runner env (with

+# Why this workflow exists: publish-workspace-server-image builds and
+# pushes a new platform-tenant :<sha> to ECR on every merge to main,
+# but running tenants pulled their image once at boot and never re-pull.
+# Users see stale code indefinitely.
+#
+# This workflow closes the gap by calling the control-plane admin
+# endpoint that performs a canary-first, batched, health-gated rolling
+# redeploy across every live tenant. Implemented in molecule-ai/
+# molecule-controlplane as POST /cp/admin/tenants/redeploy-fleet
+# (feat/tenant-auto-redeploy, landing alongside this workflow).
+#
+# Registry: ECR (153263036946.dkr.ecr.us-east-2.amazonaws.com/

+#      ECR image manifest is consistent immediately after push.
+#   3. Calls redeploy-fleet with canary_slug (if set) and a soak
+#      period. Canary proves the image boots; batches follow.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.
+#
+# Rollback path: re-run this workflow with a specific SHA pinned via

+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#   - **Gitea workflow_run trigger limitation**: Gitea 1.22.6's support
+#     for the `workflow_run` event is partial. If this never fires on a
+#     real publish-workspace-server-image completion, the follow-up
+#     triage PR should replace the trigger with a push-with-paths-filter
+#     on .gitea/workflows/publish-workspace-server-image.yml. Until
+#     then continue-on-error+dead-workflow doesn't break anything.

+# Auto-refresh staging tenant EC2s after every staging-branch merge.
+#
+# Mirror of redeploy-tenants-on-main.yml, with the staging-CP host and
+# the :staging-latest tag. Sister workflow exists for prod (rolls
+# :latest after staging-verify). Both share the same shape — just
+# different CP_URL + target_tag + admin token secret.
+#
+# Why this workflow exists: publish-workspace-server-image now builds
+# on every staging-branch push (PR #2335), pushing
+# platform-tenant:staging-latest to GHCR. Existing tenants pulled
+# their image once at boot and never re-pull, so the new image just
+# sits unused until the tenant is reprovisioned.
+#
+# This workflow closes the gap by calling staging-CP's
+# /cp/admin/tenants/redeploy-fleet, which performs a canary-first,
+# batched, health-gated SSM redeploy across every live staging tenant.
+# Same endpoint shape as prod CP — only the host differs.
+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes on staging branch →
+#      new :staging-latest in GHCR.
+#   2. This workflow fires via workflow_run, waits 30s for GHCR's CDN
+#      to propagate the new tag.
+#   3. Calls redeploy-fleet with no canary (staging IS canary; we don't
+#      need a sub-canary inside it). Soak still applies to the first
+#      tenant in case of bad-deploy detection.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.

+# Rollback path: re-run with workflow_dispatch + target_tag=staging-<sha>

+# PUBLISHED if THIS PR merges.
+#
+# Why two workflows: the chicken-and-egg #128 fix added a "PR-built
+# wheel" job to the original runtime-pin-compat.yml, but both jobs
+# shared a `paths:` filter that was the union of their needs
+# (`workspace/**`). That meant the PyPI-latest job ran on every doc
+# edit even though the upstream PyPI artifact can't change with our
+# workspace/ source. Splitting the two means each gets a narrow
+# `paths:` filter that matches the inputs it actually depends on.
+#
+# Catches the failure mode where a PR adds an import requiring a newer
+# SDK than `workspace/requirements.txt` pins:
+#   1. Pip resolves the existing PyPI wheel + the old SDK pin -> smoke
+#      passes (it imports the OLD main.py from the wheel, not the PR's
+#      new main.py).
+#   2. Merge -> publish-runtime.yml ships a wheel WITH the new import.
+#   3. Tenant images redeploy -> all crash on first boot with ImportError.

+# sop-tier-refire — issue_comment-triggered refire of sop-tier-check.
+#
+# Closes internal#292. Gitea 1.22.6 doesn't refire workflows on the
+# `pull_request_review` event (go-gitea/gitea#33700); the `sop-tier-check`
+# workflow's review-event subscription is silently dead. The result:
+# PRs that get their approving review AFTER the tier-check ran on open/
+# synchronize keep their failing status check forever, and the only way
+# to merge is the admin force-merge path (audited via `audit-force-merge`
+# but the audit trail keeps growing; see `feedback_never_admin_merge_bypass`).
+#
+# Workaround pattern from `feedback_pull_request_review_no_refire`:
+# `issue_comment` events DO fire reliably on 1.22.6. When a repo
+# MEMBER/OWNER/COLLABORATOR comments `/refire-tier-check` on a PR, this
+# workflow re-runs the sop-tier-check logic and POSTs the resulting
+# status to the PR head SHA directly. No empty commit, no git history
+# bloat, no cascade re-fire of every other workflow on the PR.
+#
+# SECURITY MODEL:
+#
+# 1. `pull_request` exists on the issue (issue_comment fires on issues
+#    AND PRs; we only want PRs).
+# 2. `comment.author_association` must be MEMBER/OWNER/COLLABORATOR.
+#    Per the internal#292 core-security review (review#1066 ask): anyone
+#    can comment, but only repo collaborators+ can flip the status.
+#    Without this gate, a drive-by commenter on a public-issue-tracker
+#    surface could trigger a status flip.
+# 3. Comment body must contain `/refire-tier-check` — a slash-command-
+#    shaped trigger (not just any comment word). Prevents accidental
+#    triggering from prose like "we should refire tests" in a review.
+# 4. This workflow does NOT check out PR HEAD code. Like sop-tier-check,
+#    it only HTTP-calls the Gitea API. Trust boundary preserved.
+#
+# Note: `issue_comment` fires from the BASE branch's workflow file. There
+# is no `pull_request_target` equivalent to set; the trigger inherently
+# loads the workflow from the default branch.
+#
+# Rate-limit: a 1s pre-sleep + a "skip if status posted in last 30s"

+# internal#219 §1 sweep. Differences from the GitHub version:
+#   - Dropped `workflow_dispatch.inputs` (Gitea 1.22.6 parser rejects them
+#     per feedback_gitea_workflow_dispatch_inputs_unsupported).
+#   - Dropped `merge_group:` (no Gitea merge queue).
+#   - Dropped `environment:` blocks (Gitea has no environments).
+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#   - **Gitea workflow_run trigger limitation**: Gitea 1.22.6's support
+#     for the `workflow_run` event is partial. If this never fires on a
+#     real publish-workspace-server-image completion, the follow-up
+#     triage PR should replace the trigger with a push-with-paths-filter
+#     on the same publish workflow's path (i.e. `.gitea/workflows/publish-workspace-server-image.yml`).

+# Runs the canary smoke suite against the staging canary tenant fleet
+# after a new :staging-<sha> image lands in ECR. On green, calls the
+# CP redeploy-fleet endpoint to promote :staging-<sha> → :latest so
+# the prod tenant fleet's 5-minute auto-updater picks up the verified
+# digest. On red, :latest stays on the prior known-good digest and
+# prod is untouched.
+#
+# Terminology note (2026-05-11): The deployment STRATEGY here is still
+# called "canary release" (a small subset of tenants gets the new image
+# first, the rest follow on green). The "canary" word stays for the
+# pre-fan-out cohort concept (see docs/architecture/canary-release.md
+# and CANARY_SLUG in redeploy-tenants-on-*.yml). What changed is the
+# FILE NAME and the SECRETS feeding this workflow — both are renamed
+# to drop the redundant "canary-" prefix that conflated workflow
+# identity with deployment strategy.
+#
+# Registry note (2026-05-10): This workflow previously used GHCR
+# (ghcr.io/molecule-ai/platform-tenant) — that registry was retired
+# during the 2026-05-06 Gitea suspension migration when publish-
+# workspace-server-image.yml switched to the operator's ECR org
+# (153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/
+# platform-tenant). The GHCR → ECR migration was never applied to
+# this file, so this workflow was silently smoke-testing the stale
+# GHCR image while the actual staging/prod tenants ran the ECR image.
+# Result: smoke tests could not catch a broken ECR build. Fix:
+#   - Wait step: reads SHA from running canary /health (tenant-
+#     agnostic, works regardless of registry).
+#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=
+#     staging-<sha>, same mechanism as redeploy-tenants-on-main.yml.
+#     No longer attempts GHCR crane ops.
+#
+# Dependencies:
+#   - publish-workspace-server-image.yml publishes :staging-<sha>
+#     to ECR on staging and main merges.
+#   - Canary tenants are configured to pull :staging-<sha> from ECR
+#     (TENANT_IMAGE env set to the ECR :staging-<sha> tag).
+#   - Repo secrets MOLECULE_STAGING_TENANT_URLS /
+#     MOLECULE_STAGING_ADMIN_TOKENS / MOLECULE_STAGING_CP_SHARED_SECRET
+#     are populated.

+# 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

+# Why this exists separately from a long-term reconciler integration:
+#   - molecule-controlplane's tenant_resources audit table (mig 024)
+#     currently tracks four resource kinds: CloudflareTunnel,
+#     CloudflareDNS, EC2Instance, SecurityGroup. SecretsManager is
+#     not in the list, so the existing reconciler doesn't catch
+#     orphan secrets.
+#   - At ~$0.40/secret/month the cost grew to ~$19/month before this
+#     sweeper was written, indicating ~45+ orphan secrets from
+#     crashed provisions and incomplete deprovision flows.
+#   - The proper fix (KindSecretsManagerSecret + recorder hook +
+#     reconciler enumerator) is filed as a separate controlplane
+#     issue. This sweeper is the immediate cost-relief stopgap.

+# if ListSecrets is revoked in future, a dedicated janitor principal

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

-name: CodeQL
-
-# Stub workflow — CodeQL Action is structurally incompatible with Gitea
-# Actions (post-2026-05-06 SCM migration off GitHub).
-#
-# Why this is a stub, not a real CodeQL run:
-#
-# 1. github/codeql-action/init@v4 hits api.github.com endpoints
-#    (CodeQL CLI bundle download + query-pack registry + telemetry)
-#    that Gitea 1.22.x does NOT proxy. The act_runner has
-#    GITHUB_SERVER_URL=https://git.moleculesai.app correctly set
-#    (per saved memory feedback_act_runner_github_server_url and
-#    /config.yaml on the operator host), but the Gitea API surface
-#    simply does not implement the codeql-action bundle endpoints.
-#    Observed in run 1d/3101 (2026-05-07): "::error::404 page not
-#    found" inside the Initialize CodeQL step, before any analysis.
-#
-# 2. PR #35 attempted to mark `continue-on-error: true` at the JOB
-#    level (correct YAML structure). Gitea 1.22.6 does NOT propagate
-#    job-level continue-on-error to the commit-status API — every
-#    matrix leg still posts `failure` to the status surface, which
-#    keeps OVERALL=failure on every push to main + staging and
-#    blocks visual auto-promote signals (#156).
-#
-# 3. Hongming policy decision (2026-05-07, task #156): CodeQL is
-#    ADVISORY, not blocking, on Gitea Actions. We do not block PR
-#    merge or staging→main promotion on CodeQL findings until we
-#    have a Gitea-compatible static-analysis pipeline.
-#
-# What this stub preserves:
-#
-# - Workflow name `CodeQL` (referenced by auto-promote-staging.yml
-#   line 67 as a workflow_run gate — must stay stable).
-# - Job name template `Analyze (${{ matrix.language }})` and the
-#   3-leg matrix (go, javascript-typescript, python). Branch
-#   protection / required-check parity (#144) keys on these
-#   exact context names.
-# - merge_group + push + pull_request + schedule triggers, so the
-#   merge-queue check name still resolves (per saved memory
-#   feedback_branch_protection_check_name_parity).
-#
-# Re-enabling real analysis (future work):
-#
-# - Option A: self-hosted Semgrep / OpenGrep via a custom action
-#   that doesn't hit api.github.com. Tracked behind #156 follow-up.
-# - Option B: Sonatype Nexus IQ or similar, called from a step
-#   that uses the Gitea-issued token only.
-# - Option C: re-host this workflow on a small GitHub mirror used
-#   ONLY for SAST (push-mirrored from Gitea). Acceptable trade-off
-#   if/when payment is restored on a non-suspended GitHub org —
-#   but per saved memory feedback_no_single_source_of_truth, we
-#   should design for multi-vendor backup, not GitHub-only SAST.
-#
-# Until one of those lands, this stub keeps commit-status green so
-# the auto-promote chain isn't permanently red on a tool we cannot
-# actually run.
-#
-# Security policy: ADVISORY. We accept the residual risk of un-scanned
-# pushes during this window. Compensating controls in place:
-#   - secret-scan.yml runs on every push (active, blocks on hits)
-#   - block-internal-paths.yml blocks forbidden file paths
-#   - lint-curl-status-capture.yml catches one specific class of bug
-#   - branch-protection-drift.yml + the merge_group required-checks
-#     parity keep the gate surface stable
-# These are not equivalent to CodeQL coverage. Status of the

-# PR-time guards. Today the only guard is "disable auto-merge when a
-# new commit is pushed after auto-merge was enabled" — added 2026-04-27
-# after PR #2174 auto-merged with only its first commit because the
-# second commit was pushed after the merge queue had locked the PR's
-# SHA.
-#
-# Why this is inlined (not delegated to molecule-ci's reusable
-# workflow): the reusable workflow uses `gh pr merge --disable-auto`,
-# which calls GitHub's GraphQL API. Gitea has no GraphQL endpoint and
-# returns HTTP 405 on /api/graphql, so the job failed on every Gitea
-# PR push since the 2026-05-06 migration. Gitea also has no `--auto`
-# merge primitive that this job could be acting on, so the right
-# behaviour on Gitea is "no-op + green status" — not a 405.
-#
-# Inlining (vs. an `if:` on the `uses:` line) keeps the job ALWAYS
-# running, which matters for branch protection: required-check names
-# need a job that emits SUCCESS terminal state, not SKIPPED. See
-# `feedback_branch_protection_check_name_parity` and `feedback_pr_merge_safety_guards`.

-# DEPRECATED on Gitea Actions — this file is kept for reference only.
-# Gitea Actions reads .gitea/workflows/, not .github/workflows/.
-# The canonical version is now: .gitea/workflows/publish-runtime.yml
-# That port:
-#   - Drops OIDC trusted publisher (Gitea has no environments/OIDC)
-#   - Uses PYPI_TOKEN secret instead of gh-action-pypi-publish
-#   - Uses ${GITHUB_REF#refs/tags/} instead of github.ref_name
-#   - Drops staging branch trigger (staging branch does not exist)
-#   - Drops merge_group trigger (Gitea has no merge queue)
-#
-# Publishes molecule-ai-workspace-runtime to PyPI from monorepo workspace/.
-# Monorepo workspace/ is the only source-of-truth for runtime code; this
-# workflow is the bridge from monorepo edits to the PyPI artifact that
-# the 8 workspace-template-* repos depend on.
-#
-# Triggered by:
-#   - Pushing a tag matching `runtime-vX.Y.Z` (the version is derived from
-#     the tag — `runtime-v0.1.6` publishes `0.1.6`).
-#   - Manual workflow_dispatch with an explicit `version` input (useful for
-#     dev/test releases without tagging the repo).
-#   - Auto: any push to `staging` that touches `workspace/**`. The version
-#     is derived by querying PyPI for the current latest and bumping the
-#     patch component. This closes the human-in-loop gap that caused the
-#     2026-04-27 RuntimeCapabilities ImportError outage — adapter symbol
-#     additions in workspace/adapters/base.py used to require an operator
-#     to remember to publish; now the merge itself triggers the publish.
-#
-# The workflow:
-#   1. Runs scripts/build_runtime_package.py to copy workspace/ →
-#      build/molecule_runtime/ with imports rewritten (`a2a_client` →
-#      `molecule_runtime.a2a_client`).
-#   2. Builds wheel + sdist with `python -m build`.
-#   3. Publishes to PyPI via the PyPA Trusted Publisher action (OIDC).
-#      No static API token is stored — PyPI verifies the workflow's
-#      OIDC claim against the trusted-publisher config registered for
-#      molecule-ai-workspace-runtime (molecule-ai/molecule-core,
-#      publish-runtime.yml, environment pypi-publish).
-#
-# After publish: the 8 template repos pick up the new version on their
-# next image rebuild (their requirements.txt pin
-# `molecule-ai-workspace-runtime>=0.1.0`, so any new release is eligible).
-# To force-pull immediately, bump the pin in each template repo's
-# requirements.txt and merge — that triggers their own publish-image.yml.

-      # Canary-gated release flow:
-      #   - This step always publishes :staging-<sha> + :staging-latest.
-      #   - On staging push, staging-CP picks up :staging-latest immediately
-      #     (its TENANT_IMAGE pin is :staging-latest) — so staging-branch
-      #     code reaches staging tenants without waiting for main.
-      #   - On main push, canary-verify.yml runs smoke tests against
-      #     canary tenants (which pin :staging-<sha>), and on green retags
-      #     :staging-<sha> → :latest. Prod tenants pull :latest.
-      #   - On red, :latest stays on the prior good digest — prod is safe.
-      #
-      # Why :staging-latest is retagged on main push too: when main lands
-      # after a staging promote, staging-CP gets the post-promote code so
-      # the canary-on-staging-CP step still runs against the prod-bound
-      # digest. In a healthy flow the post-promote main code == the
-      # current staging code, so this is effectively a no-op except for
-      # the canary fleet pin handoff.
-      #
-      # Pre-fix history: this workflow used to only trigger on main. That
-      # meant staging-CP served "yesterday's main" indefinitely whenever
-      # staging→main was wedged. The 2026-04-30 dogfooding session
-      # surfaced this when RFC #2312 (chat upload HTTP-forward) landed on
-      # staging but staging tenants kept failing chat upload because they
-      # were running pre-RFC code. Adding the staging trigger above closes
-      # that gap. Earlier 2026-04-24 incident: a static :staging-<sha> pin

+ * Tests for ExternalConnectModal — the modal surfaced after creating a
+ * runtime="external" workspace. Surfaces workspace_auth_token + ready-to-paste
+ * snippets so the operator can configure their off-host agent.
+ *
+ * Coverage:
+ *   - Renders nothing when info=null
+ *   - Opens dialog when info is provided
+ *   - Default tab: "Universal MCP" when universal_mcp_snippet present, else "Python SDK"
+ *   - Tab switching between all available tabs
+ *   - Snippets show with auth_token replacing placeholders
+ *   - Copy button: calls clipboard API, shows "Copied!", clears after 1.5s
+ *   - Copy failure: shows fallback textarea
+ *   - "I've saved it — close" calls onClose
+ *   - Security warning: one-time token display
+ *   - Fields tab shows raw values
+ *   - Tabs hidden when their snippet is absent
+ *
+ * Fake timers: applied per-describe to avoid mixing with waitFor. Tests that
+ * use waitFor (which needs real timers) run without fake timers. Tests that
+ * verify setTimeout behavior use vi.useFakeTimers() + act(vi.advanceTimersByTime).
