Merge branch 'main' into ci/fix-detect-changes-commits-array

Gitea Compare API rejects SHA-to-branch comparisons (returns
"BaseNotExist"). The previous push-event fix (PR #497) used
github.event.before (SHA) as BASE and GITHUB_REF (branch name)
as HEAD — which fails.

Fix: for push events, extract changed files directly from
github.event.commits array (each commit has added/removed/
modified file lists). This is already in-memory from the push
event payload — no extra API call needed.

Pull request path continues to use Compare API (branch-to-branch
works fine).

+"""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()`.

+# 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

+# (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

+
+# 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.

+#   - 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

+#   - 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).

+# 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)

+#   - 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

+#
+
+# 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
+# a public route in router.go but forgot to add it to TenantGuard's
+# allowlist. The handler-level test in buildinfo_test.go constructed a

+# redeploy verifier), but no one ran the harness pre-merge. The bug
+# shipped; the redeploy verifier silently soft-warned every tenant as

+#
+# Differences from the GitHub version:
+#   - on.paths and the lint scanner target .gitea/workflows/**.yml (the
+#     active Gitea workflow directory) instead of .github/workflows/**.yml
+#     (which the rest of this sweep is emptying out).
+#   - Self-skip path updated to the .gitea/ version of this file.
+#   - Dropped `merge_group:` trigger.
+#   - Workflow-level env.GITHUB_SERVER_URL set per
+#     feedback_act_runner_github_server_url.
+#   - `continue-on-error: true` on the job (RFC §1 contract).
+#
+# Pins the workflow-bash anti-pattern that produced "HTTP 000000" on the
+# 2026-05-04 redeploy-tenants-on-main run for sha 2b862f6:
+#
+#   HTTP_CODE=$(curl ... -w '%{http_code}' ... || echo "000")
+#
+# When curl exits non-zero (connection reset -> 56, --fail-with-body 4xx/5xx
+# -> 22), the `-w '%{http_code}'` already wrote a status to stdout — usually
+# "000" for connection failures or the actual code for HTTP errors. The
+# `|| echo "000"` then fires AND appends ANOTHER "000" to the captured
+# stdout, producing values like "000000" or "409000" that fail string
+# comparisons against "200" while looking superficially right.
+#
+# Same class of bug the synth-E2E §7c gate hit twice (PRs #2779/#2783 +
+# #2797). Memory: feedback_curl_status_capture_pollution.md.

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

+# Ported from .github/workflows/redeploy-tenants-on-staging.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 .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>
+# of a known-good build.

+# 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.

+# Renamed from canary-staging.yml on 2026-05-11 per Hongming directive
+# ("canary naming changed to staging for all"). Originally ported from
+# .github/workflows/canary-staging.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).
+#
+
+# 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
+# issue on the next green run.
+#
+# The full-SaaS workflow (e2e-staging-saas.yml) covers the broader surface
+# but runs only on provisioning-critical pushes + nightly — this one
+# catches drift in the 30-min window between those runs (AMI health, CF
+# cert rotation, WorkOS session stability, etc.).
+#
+# Lean mode: E2E_MODE=smoke skips the child workspace + HMA memory +
+# peers/activity checks. One parent workspace + one A2A turn is enough
+# to signal "SaaS stack end-to-end is alive."

+#   - **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.

+# 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

+#   - sweep-cf-orphans.sh enumerates the CF zone directly and matches

+#     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

+# 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
+# workflow is the safety net that catches everything else AND any
+# future leak source we haven't yet identified.

-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

-#
-# Why this is inlined (not delegated to molecule-ci's reusable

-#
-# Inlining (vs. an `if:` on the `uses:` line) keeps the job ALWAYS

-# 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.

-      #     :staging-<sha> → :latest. Prod tenants pull :latest.

-      # Pre-fix history: this workflow used to only trigger on main. That
-      # meant staging-CP served "yesterday's main" indefinitely whenever

-      # surfaced this when RFC #2312 (chat upload HTTP-forward) landed on
