+"""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()`.

+# 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 "managers" OR "ceo"
+#
+# Per the spec (internal#189), the hard gate here pairs with the

+#     _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

+# Ported from .github/workflows/ci.yml on 2026-05-11 per RFC internal#219 §1.
+# continue-on-error: true on every job; follow-up PR will flip required after
+# surfaced bugs are fixed (per RFC §1 — "surface broken workflows without
+# blocking"). The four-surface migration audit
+# (feedback_gitea_actions_migration_audit_pattern) was performed against this
+# port:
+#
+#   1. YAML — dropped `merge_group` trigger (no Gitea merge queue); no
+#      `workflow_dispatch.inputs` to drop (Gitea 1.22.6 rejects those —
+#      feedback_gitea_workflow_dispatch_inputs_unsupported); no `environment:`
+#      blocks; kept `runs-on: ubuntu-latest` (Gitea runner pool advertises
+#      this label per agent_labels in action_runner table). Workflow-level
+#      env.GITHUB_SERVER_URL set as belt-and-suspenders against runner
+#      defaults (feedback_act_runner_github_server_url).
+#
+#   2. Cache — `actions/upload-artifact@v3.2.2` was already pinned to v3 for
+#      Gitea act_runner v0.6 compatibility (a comment in the original called
+#      this out). v4+ is incompatible with Gitea 1.22.x. No `actions/cache`
+#      usage to audit. `actions/setup-python@v6` `cache: pip` is left in
+#      place — works against Gitea's built-in cache server when runner.cache
+#      is configured (currently is, /opt/molecule/runners/config.yaml).
+#
+#   3. Token — workflow uses no custom dispatch tokens. The auto-injected
+#      `GITHUB_TOKEN` (which Gitea aliases to a runner-scoped token) is
+#      sufficient for `actions/checkout` against this same repo.
+#
+#   4. Docs — no docs/scripts reference github.com URLs that need swapping.
+#      The canvas-deploy-reminder step writes a `ghcr.io/...` image
+#      reference into the step summary text — that's documentation prose
+#      pointing at the ECR-mirrored canvas image and stays unchanged for
+#      this port (a separate cleanup if ghcr→ECR sweep is in scope).

+# Cross-links:

+#   - Bugs that may surface immediately and are tracked separately:
+#     internal#214 (Go-side vanity-import / go.sum drift, if any)
+#   - Phase 4 (this PR's follow-up): flip `continue-on-error: false` once

+
+# 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.
+

+  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.

+# Ported from .github/workflows/e2e-api.yml on 2026-05-11 per RFC
+# internal#219 §1 sweep. Differences from the GitHub version:
+#   - Dropped `workflow_dispatch.inputs` (Gitea 1.22.6 parser rejects them
+#     per feedback_gitea_workflow_dispatch_inputs_unsupported).
+#   - Dropped `merge_group:` (no Gitea merge queue).
+#   - Dropped `environment:` blocks (Gitea has no environments).
+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#
+# 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.

+# Ported from .github/workflows/e2e-staging-saas.yml on 2026-05-11 per RFC
+# internal#219 §1 sweep. Differences from the GitHub version:
+#   - Dropped `workflow_dispatch.inputs` (Gitea 1.22.6 parser rejects them
+#     per feedback_gitea_workflow_dispatch_inputs_unsupported).
+#   - Dropped `merge_group:` (no Gitea merge queue).

+#   - Workflow-level env.GITHUB_SERVER_URL pinned per

+#
+
+# Dedicated workflow that provisions a fresh staging org per run, exercises
+# the full workspace lifecycle (register → heartbeat → A2A → delegation →
+# HMA memory → activity → peers), then tears down and asserts leak-free.
+#
+# Why a separate workflow (not folded into ci.yml):
+#   - The run takes ~25-35 min (EC2 boot + cloudflared DNS + provision sweeps +
+#     agent bootstrap), way too slow for every PR.
+#   - Needs its own concurrency group so two pushes don't fight over the
+#     same staging org slug prefix.
+#   - Has its own required secrets (session cookie, admin token) that most
+#     PRs don't need to read.
+#
+# Triggers:
+#   - Push to main (regression guard)
+#   - workflow_dispatch (manual re-run from UI)
+#   - Nightly cron (catches drift even when no pushes land)
+#   - Changes to any provisioning-critical file under PR review (opt-in

+#   - 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).

+#
+
+# 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.
+#
+# Cost: ~30s job (postgres pull from cache + go build + 4 tests).

+#   This file computes the next version from PyPI's latest, pushes a

+# 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.

+#     repeat-drift, close on clean run.
+#   - Workflow-level env.GITHUB_SERVER_URL set so the curl calls can

+# Auto-refresh prod tenant EC2s after every main merge.
+#
+# Why this workflow exists: publish-workspace-server-image builds and
+# pushes a new platform-tenant :<sha> to ECR on every merge to main,
+# but running tenants pulled their image once at boot and never re-pull.
+# Users see stale code indefinitely.
+#
+# This workflow closes the gap by calling the control-plane admin
+# endpoint that performs a canary-first, batched, health-gated rolling
+# redeploy across every live tenant. Implemented in molecule-ai/
+# molecule-controlplane as POST /cp/admin/tenants/redeploy-fleet
+# (feat/tenant-auto-redeploy, landing alongside this workflow).
+#
+# Registry: ECR (153263036946.dkr.ecr.us-east-2.amazonaws.com/

+#
+# Runtime ordering:
+#   1. publish-workspace-server-image completes → new :staging-<sha> in ECR.
+#   2. This workflow fires via workflow_run, calls redeploy-fleet with
+#      target_tag=staging-<sha>. No CDN propagation wait needed —
+#      ECR image manifest is consistent immediately after push.
+#   3. Calls redeploy-fleet with canary_slug (if set) and a soak
+#      period. Canary proves the image boots; batches follow.
+#   4. Any failure aborts the rollout and leaves older tenants on the
+#      prior image — safer default than half-and-half state.
+#
+# Rollback path: re-run this workflow with a specific SHA pinned via

+#   - **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

+# 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>

+# Ported from .github/workflows/runtime-prbuild-compat.yml on 2026-05-11
+# per RFC internal#219 §1 sweep.
+#
+# Differences from the GitHub version:
+#   - Dropped `merge_group:` (no Gitea merge queue) and `workflow_dispatch:`
+#     (Gitea 1.22.6 parser-rejects workflow_dispatch with inputs and is
+#     finicky without them).
+#   - `dorny/paths-filter@v4` replaced with inline `git diff` (per PR#372
+#     pattern for ci.yml port).
+#   - on.paths references .gitea/workflows/runtime-prbuild-compat.yml.
+#   - Workflow-level env.GITHUB_SERVER_URL set.
+#   - `continue-on-error: true` on every job (RFC §1 contract).
+#
+# Companion to `runtime-pin-compat.yml`. That workflow tests what's
+# CURRENTLY PUBLISHED on PyPI; this workflow tests what WOULD BE
+# PUBLISHED if THIS PR merges.
+#
+# Why two workflows: the chicken-and-egg #128 fix added a "PR-built
+# wheel" job to the original runtime-pin-compat.yml, but both jobs
+# shared a `paths:` filter that was the union of their needs
+# (`workspace/**`). That meant the PyPI-latest job ran on every doc
+# edit even though the upstream PyPI artifact can't change with our
+# workspace/ source. Splitting the two means each gets a narrow
+# `paths:` filter that matches the inputs it actually depends on.
+#
+# Catches the failure mode where a PR adds an import requiring a newer
+# SDK than `workspace/requirements.txt` pins:
+#   1. Pip resolves the existing PyPI wheel + the old SDK pin -> smoke
+#      passes (it imports the OLD main.py from the wheel, not the PR's
+#      new main.py).
+#   2. Merge -> publish-runtime.yml ships a wheel WITH the new import.
+#   3. Tenant images redeploy -> all crash on first boot with ImportError.

+# sop-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"
+# guard prevents comment-spam from thrashing the status. See the script.

+#     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).

+# Minimum viable health check: provisions one Hermes workspace on a fresh
+# staging org, sends one A2A message, verifies PONG, tears down. ~8 min
+# wall clock. Pages on failure by opening a GitHub issue; auto-closes the

+# Renamed from canary-verify.yml on 2026-05-11 per Hongming directive
+# ("canary naming changed to staging for all"). Originally ported from
+# .github/workflows/canary-verify.yml on 2026-05-11 per RFC
+# internal#219 §1 sweep. Differences from the GitHub version:
+#   - Dropped `workflow_dispatch.inputs` (Gitea 1.22.6 parser rejects them
+#     per feedback_gitea_workflow_dispatch_inputs_unsupported).
+#   - Dropped `merge_group:` (no Gitea merge queue).
+#   - Dropped `environment:` blocks (Gitea has no environments).
+#   - Workflow-level env.GITHUB_SERVER_URL pinned per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on each job (RFC §1 contract).
+#   - **Gitea workflow_run trigger limitation**: 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.

+#
+# 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.

+# IAM principal: AWS_JANITOR_ACCESS_KEY_ID / AWS_JANITOR_SECRET_ACCESS_KEY.
+# This is a DEDICATED principal — the production `molecule-cp` IAM
+# user lacks `secretsmanager:ListSecrets` (it only has
+# Get/Create/Update/Delete on specific resources, scoped to its
+# operational needs). The janitor needs ListSecrets across the
+# `molecule/tenant/*` prefix, which warrants a separate principal so
+# we don't broaden the prod-CP policy.

+# 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

+#     itself never knew about the tenant (canary scratch, manual ops

+#     leaks the CP-driven sweep can't.
+#
+# Safety: the script's own MAX_DELETE_PCT gate refuses to nuke more

+# CI cancellations, runner crashes, transient AWS errors mid-cascade,
+# bash trap missed (signal 9), etc. Without this loop, every failed
+# teardown leaks an EC2 + DNS + DB row until manual ops cleanup —
+# 2026-04-23 staging hit the 64 vCPU AWS quota from ~27 such orphans.
+#
+# Why not rely on per-test-run teardown:
+#   - Per-run teardown is best-effort by definition. Any process death
+#     after the test starts but before the trap fires leaves debris.
+#   - GH Actions cancellation kills the runner without grace period.
+#     The workflow's `if: always()` step usually catches this, but it
+#     too can fail (CP transient 5xx, runner network issue at the
+#     wrong moment).
+#   - Even when teardown runs, the CP cascade is best-effort in places
+#     (cascadeTerminateWorkspaces logs+continues; DNS deletion same).
+#   - This sweep is the catch-all that converges staging back to clean
+#     regardless of which specific path leaked.
+#
+# The PROPER fix is making CP cleanup transactional + verify-after-
+# terminate (filed separately as cleanup-correctness work). This

-name: Auto-promote :latest after main image build
-
-# Retags `ghcr.io/molecule-ai/{platform,platform-tenant}:staging-<sha>`
-# → `:latest` after either the image build or E2E completes on a `main`
-# push, gated on E2E Staging SaaS not being red for that SHA.
-#
-# Why two triggers:
-#
-#   `publish-workspace-server-image` and `e2e-staging-saas` are both
-#   paths-filtered, but with DIFFERENT path sets:
-#
-#     publish-workspace-server-image:
-#       workspace-server/**, canvas/**, manifest.json
-#
-#     e2e-staging-saas (full lifecycle):
-#       workspace-server/internal/handlers/{registry,workspace_provision,
-#       a2a_proxy}.go, workspace-server/internal/middleware/**,
-#       workspace-server/internal/provisioner/**, tests/e2e/test_staging_full_saas.sh
-#
-#   The E2E set is a strict SUBSET of the publish set. So:
-#     - canvas/** changes → publish fires, E2E does not
-#     - workspace-server/cmd/** changes → publish fires, E2E does not
-#     - workspace-server/internal/sweep/** → publish fires, E2E does not
-#
-#   The previous version triggered ONLY on E2E completion, which meant
-#   non-E2E-path changes (canvas, cmd, sweep, etc.) rebuilt the image
-#   but never advanced `:latest`. Result: as of 2026-04-28 this workflow
-#   had run zero times since merge despite eight main pushes — `:latest`
-#   was ~7 hours / 9 PRs behind main with no human realising. See
-#   `molecule-core` Slack discussion 2026-04-28.
-#
-#   Adding `publish-workspace-server-image` as a second trigger closes
-#   the gap: any image rebuild on main eligibly advances `:latest`.
-#
-# Why E2E remains a kill-switch (not the trigger):
-#
-#   When E2E DID run for this SHA and ended red, we abort — `:latest`
-#   stays on the prior known-good digest. When E2E didn't run (paths
-#   filtered out), we proceed: pre-merge gates already validated this
-#   SHA on staging via auto-promote-staging requiring CI + E2E Canvas +
-#   E2E API + CodeQL all green. Image content for non-E2E-paths
-#   (canvas, cmd, sweep) is exercised by those staging gates.
-#
-# Why `main` only:
-#
-#   `:latest` is what prod tenants pull. We only want SHAs that have
-#   reached main (via auto-promote-staging) to advance `:latest`.
-#   Triggering on staging would let a staging-only revert advance
-#   `:latest` to a SHA that never reaches main, breaking the "production
-#   runs what's on main" invariant.
-#
-# Idempotency:
-#
-#   When a SHA touches paths that match BOTH publish and E2E, both
-#   workflows fire and complete. Both trigger this workflow on
-#   completion → two runs race. Both retag `:staging-<sha>` →
-#   `:latest`. crane tag is idempotent (re-tagging the same digest is a
-#   no-op), so the second run is harmless. concurrency group serializes
-#   them anyway.

-name: Auto-promote staging → main
-
-# Fires after any of the staging-branch quality gates complete. When ALL
-# required gates are green on the same staging SHA, opens (or re-uses)
-# a PR `staging → main` and schedules Gitea auto-merge so the PR lands
-# automatically once approval + status checks are satisfied.
-#
-# ============================================================
-# What this workflow does
-# ============================================================
-#
-# 1. On a workflow_run completion event for one of the staging gate
-#    workflows (CI, E2E Staging Canvas, E2E API Smoke, CodeQL),
-#    checks if the combined status on the staging head SHA is green.
-# 2. If green, opens (or re-uses) a PR `head: staging → base: main`
-#    via Gitea REST `POST /api/v1/repos/.../pulls`.
-# 3. Schedules auto-merge via `POST /api/v1/repos/.../pulls/{index}/merge`
-#    with `merge_when_checks_succeed: true`. Gitea waits for the
-#    approval requirement on `main` (`required_approvals: 1`) and
-#    the status-check gates, then merges.
-# 4. The merge commit lands on `main` and fires
-#    `publish-workspace-server-image.yml` naturally via its
-#    `on: push: branches: [main]` trigger — no explicit dispatch
-#    needed (see "Why no workflow_dispatch tail" below).
-#
-# `auto-sync-main-to-staging.yml` is the reverse-direction
-# counterpart (main → staging, fast-forward push). Together they
-# keep the staging-superset-of-main invariant tight.
-#
-# ============================================================
-# Why Gitea REST (and not `gh pr create`)
-# ============================================================
-#
-# Pre-2026-05-06 this workflow used `gh pr create`, `gh pr merge --auto`,
-# `gh run list`, and `gh workflow run` against GitHub. After the
-# GitHub→Gitea cutover those calls fail because:
-#
-#   - `gh pr create / merge / view / list` route to GitHub GraphQL
-#     (`/api/graphql`). Gitea does not expose a GraphQL endpoint;
-#     every call returns `HTTP 405 Method Not Allowed` — same root
-#     cause as #65 (auto-sync) which PR #66 fixed by dropping `gh`
-#     entirely.
-#   - `gh run list --workflow=...` GitHub-shape; Gitea has the
-#     simpler `GET /repos/.../commits/{ref}/status` combined-status
-#     endpoint instead.
-#   - `gh workflow run X.yml` calls `POST /repos/.../actions/workflows/{id}/dispatches`,
-#     which does NOT exist on Gitea 1.22.6 (verified via swagger.v1.json).
-#
-# So this workflow uses direct `curl` calls to Gitea REST. No `gh`
-# CLI dependency, no GraphQL, no missing-endpoint footgun.
-#
-# ============================================================
-# Why no workflow_dispatch tail (was load-bearing on GitHub, dead on Gitea)
-# ============================================================
-#
-# The GitHub-era version had a 60-line polling step that waited for
-# the promote PR to merge, then explicitly dispatched
-# `publish-workspace-server-image.yml` on `--ref main`. That step
-# existed because GitHub's GITHUB_TOKEN-initiated merges suppress
-# downstream `on: push` workflows (the documented "no recursion" rule
-# — https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow).
-# The explicit dispatch was the workaround.
-#
-# Gitea Actions does NOT have this no-recursion rule. PR #66's auto-
-# sync merge to main fired `auto-promote-staging` on the next push
-# trigger naturally. So the cascade fires on the natural push event;
-# the explicit dispatch is dead code. (And even if we wanted to
-# preserve it, Gitea has no `workflow_dispatch` REST endpoint.)
-#
-# Removed in this rewrite. If we ever observe the cascade misfire,
-# operator can push an empty commit to `main` to wake it.
-#
-# ============================================================
-# Why open a PR (and not direct push)
-# ============================================================
-#
-# `main` branch protection has `enable_push: false` with NO
-# `push_whitelist_usernames`. Direct push is impossible for any
-# persona, including admins. PR-mediated merge is the only path,
-# which is intentional: prod state mutations (and staging→main IS a
-# prod mutation, since the next deploy fans out to tenants) require
-# Hongming's approval per `feedback_prod_apply_needs_hongming_chat_go`.
-#
-# The auto-merge schedule preserves this gate: `merge_when_checks_succeed`
-# does NOT bypass `required_approvals: 1`. Gitea waits for BOTH
-# approval AND green checks before merging. Hongming reviews via the
-# canvas/chat-handle of the PR notification, approves, and Gitea
-# auto-merges within seconds.
-#
-# ============================================================
-# Identity + token (anti-bot-ring per saved-memory
-# `feedback_per_agent_gitea_identity_default`)
-# ============================================================
-#
-# This workflow uses `secrets.AUTO_SYNC_TOKEN` — a personal access
-# token issued to the `devops-engineer` Gitea persona. NOT the
-# founder PAT. The bot-ring fingerprint that triggered the GitHub
-# org suspension on 2026-05-06 was characterised by founder PAT
-# acting as CI at machine speed.
-#
-# Token scope: `push: true` (read+write) on this repo. The persona
-# can: open PRs, comment on PRs, schedule auto-merge. The persona
-# CANNOT bypass main's branch protection (`required_approvals: 1`
-# still applies — only Hongming's review unblocks merge).
-#
-# Authorship: the PR is opened by `devops-engineer`; the merge
-# commit credits Hongming-as-approver and `devops-engineer` as
-# the merger.
-#
-# ============================================================
-# Failure modes & operational notes
-# ============================================================
-#
-# A — staging gates not all green at trigger time:
-#     - The combined-status check returns `state: pending|failure`.
-#       Workflow exits 0 with a step-summary "not all green; staying
-#       on current main". Re-fires on the next gate completion.
-#
-# B — Gitea PR-create returns non-201 (e.g. 422 already-exists):
-#     - Idempotent: the workflow first GETs the existing open
-#       staging→main PR. If found, reuse it; if not, POST a new one.
-#       422 should never surface; if it does (race), step summary
-#       captures the body and the next workflow_run picks up.
-#
-# C — `merge_when_checks_succeed` schedule fails:
-#     - 422 with "Pull request is not mergeable" if there are
-#       conflicts or stale base. Step summary surfaces it; operator
-#       (or `auto-sync-main-to-staging`) needs to bring staging up
-#       to date with main first. Workflow exits 1 to surface red.
-#
-# D — `AUTO_SYNC_TOKEN` rotated / wrong scope:
-#     - 401/403 on first REST call. Step summary surfaces it.
-#       Re-issue the token from `~/.molecule-ai/personas/` on the
-#       operator host and update the repo Actions secret.
-#
-# ============================================================
-# Loop safety
-# ============================================================
-#
-# When the promote PR merges to main, `auto-sync-main-to-staging.yml`
-# fires (on:push:main) and pushes the merge commit back to staging.
-# That push to staging is by `devops-engineer`, NOT this workflow's
-# token, and triggers the staging gate workflows. When they all
-# complete, we end up back here — but the tree-diff guard catches
-# it: staging tree == main tree (the merge commit changes nothing),
-# so we skip and the cycle terminates.

-name: Auto-sync canary — AUTO_SYNC_TOKEN rotation drift
-
-# Synthetic health check for the AUTO_SYNC_TOKEN secret consumed by
-# auto-sync-main-to-staging.yml (PR #66) and publish-workspace-server-image.yml.
-#
-# ============================================================
-# Why this workflow exists
-# ============================================================
-#
-# PR #66 fixed auto-sync (replaced GitHub-era `gh pr create` — which
-# 405s on Gitea's GraphQL endpoint — with a direct git push from the
-# `devops-engineer` persona's `AUTO_SYNC_TOKEN`). Hostile self-review
-# weakest spot #3 of that PR:
-#
-#   "Token rotation silently breaks auto-sync. If AUTO_SYNC_TOKEN is
-#    rotated without updating the repo secret, every push to main
-#    fails red on the auto-sync push step. The workflow surfaces the
-#    failure mode in the step summary (failure mode B in the header),
-#    but there's no proactive monitoring."
-#
-# Detection latency under the status quo: rotation is only caught on
-# the next push to `main`. During quiet periods (no main push for
-# many hours) the staging-superset-of-main invariant silently breaks.
-#
-# This workflow closes the gap: every 6 hours, it fires the auth
-# surface that auto-sync depends on and emits a red workflow status
-# if AUTO_SYNC_TOKEN has drifted out of validity.
-#
-# ============================================================
-# What this checks (Option B — read-only verify)
-# ============================================================
-#
-# 1. `GET /api/v1/user` against Gitea with the token → validates the
-#    token authenticates AND resolves to `devops-engineer` (catches
-#    the case where the token was regenerated under a different
-#    persona by mistake).
-# 2. `GET /api/v1/repos/molecule-ai/molecule-core` with the token →
-#    validates the token has `read:repository` scope on this repo
-#    (the v2 scope contract — see saved memory
-#    `reference_persona_token_v2_scope`).
-# 3. `git push --dry-run` of the current staging SHA back to
-#    `refs/heads/staging` via `https://oauth2:<token>@<gitea>/...`
-#    → validates the EXACT HTTPS basic-auth path that
-#    `actions/checkout` + `git push origin staging` use inside
-#    auto-sync-main-to-staging.yml. NOP by construction (push the
-#    current tip to itself = "Everything up-to-date"); auth is
-#    checked at the smart-protocol handshake BEFORE the empty-diff
-#    computation, so bad token → exit 128 with "Authentication
-#    failed". `git ls-remote` is NOT used here because Gitea
-#    falls back to anonymous read on public repos and would
-#    silently green-light a rotated token.
-#
-# Each step exits non-zero with an actionable error message if it
-# fails. The workflow status itself is the operator-facing surface.
-#
-# ============================================================
-# What this does NOT check (intentional)
-# ============================================================
-#
-# - **Branch-protection authz** (failure mode C in auto-sync header):
-#   would require an actual write to staging. Already monitored by
-#   `branch-protection-drift.yml` daily. Don't duplicate.
-# - **Conflict resolution** (failure mode A): a real conflict is data-
-#   driven, not auth-driven; can't synthesise it without polluting
-#   staging. Already surfaces immediately on the next main push.
-# - **Concurrency** (failure mode D): handled by workflow concurrency
-#   group on auto-sync, not a credential issue.
-#
-# ============================================================
-# Why Option B (read-only) and not the alternatives
-# ============================================================
-#
-# Considered + rejected (see issue #72 for full write-up):
-#
-# - **Option A — full auto-sync on schedule**: every run creates a
-#   no-op merge commit on staging when main hasn't advanced. 4 noise
-#   commits/day. And races the real `push:` trigger when main has
-#   advanced. Rejected.
-#
-# - **Option C — push to dedicated `auto-sync-canary` branch**: would
-#   exercise authz too, but adds branch noise on Gitea AND requires
-#   maintaining a second branch protection (or expanding staging's
-#   whitelist to a junk branch). Authz already covered by
-#   `branch-protection-drift.yml`. Rejected.
-#
-# Prior art for the chosen Option B shape:
-#   - Cloudflare's `/user/tokens/verify` endpoint (read-only auth
-#     probe explicitly designed for credential canaries).
-#   - AWS Secrets Manager rotation Lambda's `testSecret` step (auth
-#     probe before promoting AWSPENDING → AWSCURRENT).
-#   - HashiCorp Vault's `vault token lookup` for renewal canaries.
-#
-# ============================================================
-# Operator runbook — what to do when this workflow goes RED
-# ============================================================
-#
-# 1. **Identify which step failed**:
-#    - Step "Verify token authenticates as devops-engineer" red →
-#      token is invalid OR resolves to wrong persona.
-#    - Step "Verify token has repo read scope" red → token valid but
-#      stripped of `read:repository` scope (or repo perms changed).
-#    - Step "Verify git HTTPS auth path via no-op dry-run push to
-#      staging" red → token rotated/revoked OR Gitea git-HTTPS
-#      surface is broken (rare). Auth check happens on the
-#      smart-protocol handshake, separate from the API path.
-#
-# 2. **Re-issue the token** on the operator host:
-#    ```
-#    ssh root@5.78.80.188 'docker exec --user git molecule-gitea-1 \
-#      gitea admin user generate-access-token \
-#      --username devops-engineer \
-#      --token-name persona-devops-engineer-vN \
-#      --scopes "read:repository,write:repository,read:user,read:organization,read:issue,write:issue,read:notification,read:misc"'
-#    ```
-#    Update `/etc/molecule-bootstrap/agent-secrets.env` in place
-#    (per `feedback_unified_credentials_file`). The previous token
-#    file lands at `.bak.<date>`.
-#
-# 3. **Update the repo Actions secret** at:
-#    Settings → Secrets and variables → Actions → AUTO_SYNC_TOKEN
-#    Paste the new token. (Don't echo it in chat — but per
-#    `feedback_passwords_in_chat_are_burned`, a paste in a 1:1
-#    Claude session is within trust boundary.)
-#
-# 4. **Re-run this canary** via workflow_dispatch. Confirm GREEN.
-#

-# - Token usage: read-only (`GET /api/v1/user`, `GET /api/v1/repos/...`,
-#   `git ls-remote`). No write paths. Same blast-radius profile as
-#   `actions/checkout` on a public repo.
-# - The token NEVER appears in logs: every `curl` uses a header
-#   variable, never inline; the `git ls-remote` URL builds the
-#   `oauth2:$TOKEN@host` form into a single env var that's not
-#   echoed. GitHub Actions secret-masking covers anything that does
-#   slip through.
-# - No new token introduced — same `AUTO_SYNC_TOKEN` the workflow
-#   under monitor uses. Per least-privilege we deliberately do NOT
-#   broaden scope for the canary.

-name: Auto-sync main → staging
-
-# Reflects every push to `main` back onto `staging` so the
-# staging-as-superset-of-main invariant holds.
-#
-# ============================================================
-# What this workflow does
-# ============================================================
-#
-# On every push to `main`:
-#   1. Checks if staging already contains main → no-op.
-#   2. Fetches both branches, merges main into staging in the
-#      runner workspace (fast-forward if possible, else
-#      `--no-ff` merge commit).
-#   3. Pushes staging directly to origin via the
-#      `devops-engineer` persona's `AUTO_SYNC_TOKEN`.
-#
-# Authoritative path: a single `git push origin staging` from
-# inside this workflow is the SSOT for advancing staging after
-# a main push. No PR, no merge queue, no human approval —
-# staging is mechanically maintained as a superset of main.
-#
-# `auto-promote-staging.yml` is the reverse-direction
-# counterpart (staging → main, gated on green CI). Together
-# they keep the staging-superset-of-main invariant tight.
-#
-# ============================================================
-# Why direct push (and not "open a PR")
-# ============================================================
-#
-# Pre-2026-05-06 the canonical SCM was GitHub.com, where:
-#   - The `staging` branch had a `merge_queue` ruleset that
-#     blocked ALL direct pushes (no bypass even for org
-#     admins or the GitHub Actions integration).
-#   - Therefore this workflow opened a PR via `gh pr create`
-#     and let auto-merge land it through the queue.
-#
-# Post-2026-05-06 the canonical SCM is Gitea
-# (`git.moleculesai.app/molecule-ai/molecule-core`). Gitea:
-#   - Has no `merge_queue` concept.
-#   - Allows direct push to protected branches via per-user
-#     `push_whitelist_usernames` on the branch protection.
-#   - Does not expose a GraphQL endpoint, so `gh pr create`
-#     returns `HTTP 405 Method Not Allowed
-#     (https://git.moleculesai.app/api/graphql)` — the
-#     pre-suspension architecture cannot work on Gitea.
-#
-# The molecule-ai/molecule-core staging branch protection
-# (verified via `GET /api/v1/repos/.../branch_protections`)
-# whitelists `devops-engineer` for direct push. So the
-# correct Gitea-shape architecture is: authenticate as
-# `devops-engineer`, merge locally, push staging directly.
-#
-# This is structurally simpler than the GitHub-era PR dance
-# and removes the dependence on `gh` CLI / GraphQL entirely.
-#
-# ============================================================
-# Identity + token (anti-bot-ring per saved-memory
-# `feedback_per_agent_gitea_identity_default`)
-# ============================================================
-#
-# This workflow uses `secrets.AUTO_SYNC_TOKEN`, which is a
-# personal access token issued to the `devops-engineer`
-# persona on Gitea — NOT the founder PAT. The bot-ring
-# fingerprint that triggered the GitHub org suspension on
-# 2026-05-06 was characterised by founder PAT acting as CI
-# at machine speed; per-persona identities split the
-# attribution honestly.
-#
-# Token scope on Gitea: repo write. Push target restricted
-# to `staging` (this workflow is the only writer; main is
-# untouched). Compromise blast radius: bounded to staging
-# branch + this repo's read surface.
-#
-# Commits are authored by the persona email
-# `devops-engineer@agents.moleculesai.app` so commit history
-# reflects which automation produced the merge.
-#
-# ============================================================
-# Failure modes & operational notes
-# ============================================================
-#
-# A — staging has commits main doesn't, and the merge
-#     conflicts:
-#     - The `--no-ff` merge step exits non-zero. Workflow
-#       fails red. Operator (devops-engineer or human)
-#       resolves manually:
-#         git fetch origin
-#         git checkout staging
-#         git merge --no-ff origin/main
-#         # resolve conflicts
-#         git push origin staging
-#     - Step summary surfaces the conflict so the failed run
-#       is self-explanatory.
-#
-# B — `AUTO_SYNC_TOKEN` rotated / wrong scope:
-#     - `git push` step exits non-zero with `HTTP 401` /
-#       `403`. Step summary surfaces the failed push.
-#     - Re-issue the token from `~/.molecule-ai/personas/`
-#       on the operator host and update the repo Actions
-#       secret. Re-run the workflow.
-#
-# C — staging branch protection no longer whitelists
-#     `devops-engineer`:
-#     - `git push` exits non-zero with a Gitea protected-
-#       branch rejection. Step summary surfaces it.
-#     - Re-add `devops-engineer` to
-#       `push_whitelist_usernames` on the staging
-#       protection (Settings → Branches → staging).
-#
-# D — concurrent push to main while a sync is in flight:
-#     - The `concurrency` group below serialises runs.
-#       The second waits for the first; if main advances
-#       again while we're syncing, the second run picks
-#       up the new tip on its own fetch.
-#
-# ============================================================
-# Loop safety
-# ============================================================
-#
-# The push to staging from this workflow does NOT itself
-# fire a `push: branches: [main]` event (different branch),
-# so there's no risk of self-recursion. `auto-promote-staging.yml`
-# fires on `workflow_run` of CI etc. — it sees the new
-# staging tip on its next gate-completion event, NOT on this
-# push directly. No loop.

-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
-# replacement plan is tracked in #156.

-# 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.

-name: Retarget main PRs to staging
-
-# Mechanical enforcement of SHARED_RULES rule 8 ("Staging-first
-# workflow, no exceptions"). When a bot opens a PR against `main`,
-# retarget it to `staging` automatically and leave an explanatory
-# comment. Human / CEO-authored PRs (the staging→main promotion
-# PRs, etc.) are left alone — they're the authorised exception
-# to the rule.
-#
-# ============================================================
-# What this workflow does
-# ============================================================
-#
-# On `pull_request_target` opened/reopened against `main`:
-#   1. If the PR head is `staging`, skip (the auto-promote PRs
-#      MUST stay base=main).
-#   2. If the PR author is a bot, retarget the PR base to
-#      `staging` via Gitea REST `PATCH /pulls/{N}` body
-#      `{"base":"staging"}`.
-#   3. If the retarget returns 422 "pull request already exists
-#      for base branch 'staging'" (issue #1884 case: another PR
-#      on the same head already targets staging), close the
-#      now-redundant main-PR via Gitea REST instead of failing
-#      red.
-#   4. Post an explainer comment on the retargeted PR via
-#      Gitea REST `POST /issues/{N}/comments`.
-#
-# ============================================================
-# Why Gitea REST (and not `gh api / gh pr close / gh pr comment`)
-# ============================================================
-#
-# Pre-2026-05-06 this workflow used `gh api -X PATCH "repos/{owner}/{repo}/pulls/{N}" -f base=staging`
-# plus `gh pr close` and `gh pr comment`. After the GitHub→Gitea
-# cutover those calls fail because:
-#
-#   - `gh` CLI defaults to `api.github.com`. Even with `GH_HOST`
-#     pointing at Gitea, `gh pr close / comment` route through
-#     GraphQL (`/api/graphql`) which Gitea does not expose.
-#     Empirical: every `gh pr *` call returns
-#     `HTTP 405 Method Not Allowed (https://git.moleculesai.app/api/graphql)`
-#     — same root cause as #65 (auto-sync, fixed in PR #66) and
-#     #73/#195 (auto-promote, fixed in PR #78).
-#   - `gh api -X PATCH /pulls/{N}` happens to use a REST path
-#     that Gitea also has, but the `gh` host-resolution layer
-#     and pagination/retry logic don't always hit Gitea cleanly,
-#     and the cost of switching to direct `curl` is one extra
-#     line of code.
-#
-# So this workflow uses direct `curl` calls to Gitea REST. No
-# `gh` CLI dependency, no GraphQL, no flaky host-resolution.
-#
-# ============================================================
-# Identity + token (anti-bot-ring per saved-memory
-# `feedback_per_agent_gitea_identity_default`)
-# ============================================================
-#
-# Pre-fix this workflow used the per-job ephemeral
-# `secrets.GITHUB_TOKEN`. On Gitea Actions that token has
-# narrow scope and unpredictable cross-PR write capability.
-#
-# Post-fix: `secrets.AUTO_SYNC_TOKEN` (the `devops-engineer`
-# Gitea persona). Same persona used by `auto-sync-main-to-staging.yml`
-# (PR #66) and `auto-promote-staging.yml` (PR #78). Token scope:
-# `push: true` repo write, sufficient for PR-edit + close + comment.
-#
-# Why this token does NOT need branch-protection bypass:
-# patching a PR's base ref is a PR-level operation that does not
-# require push perms on either branch (the PR's own commits stay
-# put; only the metadata changes).
-#
-# ============================================================
-# Failure modes & operational notes
-# ============================================================
-#
-# A — PATCH base→staging returns 422 "pull request already exists"
-#     (issue #1884 case):
-#     - Detected by string-match on response body. Workflow
-#       falls through to closing the now-redundant main-PR
-#       (Gitea REST `PATCH /pulls/{N}` with `state: closed`)
-#       and posts an explanation comment. Step summary surfaces.
-#
-# B — `AUTO_SYNC_TOKEN` rotated / wrong scope:
-#     - First REST call returns 401/403. Step summary surfaces.
-#       Re-issue token from `~/.molecule-ai/personas/` on the
-#       operator host and update repo Actions secret.
-#
-# C — PR was deleted between trigger and run:
-#     - REST call returns 404. Workflow exits 0 with a notice
-#       (the rule was already enforced or the PR is gone).
-#
-# D — author is not actually a bot but the filter mis-fires:
-#     - Filter is conservative: only triggers on
-#       `user.type == 'Bot'`, `login` ends with `[bot]`, or
-#       known bot logins (`molecule-ai[bot]`, `app/molecule-ai`).
-#       Human PRs slip through unaffected. If a NEW bot login
-#       starts shipping main-PRs, add it to the filter.
