+      Gitea maps BOTH `action_run.status=2 (Failure)` AND
+      `action_run.status=3 (Cancelled)` to commit-status string
+      `"failure"`. On a busy main with
+      `concurrency: cancel-in-progress: true`, every merge burst
+      cancels prior in-flight runs (status=3) — those bubble to the
+      combined-status `failure` and inflate the watchdog's red%,
+      generating phantom `[main-red]` issues (mc#1562/#1552/#1540/...).
+      Canonical Gitea 1.22.6 enum per `models/actions/status.go` +
+      `reference_gitea_action_status_enum_corrected_2026_05_19`:

+          5=Waiting, 6=Running, 7=Blocked
+      We only want status=2 (real defects) to file. At the
+      commit-status layer we don't have the integer enum directly
+      (only the `failure` rollup string), so we use the description
+      string Gitea writes when a run is cancelled — empirically
+      `"Has been cancelled"` (verified 2026-05-19 via #1562 body).
+      Real failures show `"Failing after Ns"` and are unaffected.
+      This is option B from mc#1564 (description-string filter, no
+      extra API call). Description-string stability is a soft contract
+      with Gitea; if a future release renames it, the cancel-cascade
+      entries will simply leak back through (visible-not-silent), and
+      we'll either re-pin the string or upgrade to option A (resolve
+      the underlying action_run.status integer via target_url).

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

-# Consolidated comment dispatcher for manual review/tier refires.

 #
+# The review-refire logic (qa/security/tier slash-command dispatch) has been
+# merged into sop-checklist.yml as the `review-refire` job. This workflow
+# is kept as a no-op stub to avoid a gap during the transition window where
+# this file may be deleted while sop-checklist.yml has not yet been merged.
+#
+# After sop-checklist.yml lands, this file will be deleted (issue #1280).
+#
+# Historical behavior (superseded):
 # Gitea 1.22 queues one run per workflow subscribed to `issue_comment` before
-# evaluating job-level `if:`. SOP-heavy PRs therefore created queue storms when
-# qa-review, security-review, sop-checklist, and sop-tier-refire all
-# listened to comments. This workflow is the single non-SOP comment subscriber:
-# ordinary comments no-op quickly; slash commands post the required status
-# contexts to the PR head SHA.
+# evaluating job-level `if:`. Previously this workflow was the single
+# non-SOP comment subscriber for qa/security/tier refire slash commands.

 # RFC#351 Step 2 of 6 (implementation MVP).
 #
-# === DESIGN ===
+# === CONSOLIDATION (issue #1280) ===
 #
-# Goal: each PR must answer 7 SOP-checklist questions in its body,
-# and each item must have at least one /sop-ack <slug> comment from
-# a non-author peer in the required team. BP requires the
-# `sop-checklist / all-items-acked (pull_request)` status to merge.
+# This workflow is the SINGLE `issue_comment` subscriber — the logic from
+# `review-refire-comments.yml` has been merged in. Before this change:
+#   - sop-checklist.yml (pre-2026-05-16) → issue_comment:[created,edited,deleted] → runner slot used, job no-oped
+#   - review-refire-comments.yml           → issue_comment:[created]            → runner slot used, job no-oped
+#   → every non-refire comment occupied 2 runner slots for ~800 s each
+#      (~650 no-op runs/day, ~1,300 runner-slot-occupancy-hours/day).
 #
-# Triggers:
-#   - `pull_request_target`: opened, edited, synchronize, reopened
-#       → fires when PR opens, body is edited (refire — RFC#351 §4),
-#         or new code is pushed (head.sha changes → stale status would
-#         be auto-discarded by BP via dismiss_stale_reviews, but the
-#         status itself is per-SHA so we re-post on the new head).
-#   - `issue_comment`: created, edited, deleted
-#       → fires on any new comment so /sop-ack / /sop-revoke take
-#         effect immediately (Gitea 1.22.6 doesn't refire on
-#         pull_request_review per feedback_pull_request_review_no_refire,
-#         so issue_comment is the canonical refire channel).
+# Fix (PR #1345 / issue #1280):
+#   - ONE workflow, ONE issue_comment:[created] subscription (no edited/deleted)
+#   - all-items-acked job: pull_request_target OR sop slash-command comments
+#   - review-refire job: qa/security/tier refire slash commands
+#   → ~50% reduction in comment-triggered runner occupancy vs pre-fix.

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

-name: E2E API Smoke Test
-# Extracted from ci.yml so workflow-level concurrency can protect this job
-# from run-level cancellation (issue #458).
-#
-# Trigger model (revised 2026-04-29):
-#
-# Always FIRES on push/pull_request to staging+main. Real work is gated
-# per-step on `needs.detect-changes.outputs.api` — when paths under
-# `workspace-server/`, `tests/e2e/`, or this workflow file haven't
-# changed, the no-op step alone runs and emits SUCCESS for the
-# `E2E API Smoke Test` check, satisfying branch protection without
-# spending CI cycles. See the in-job comment on the `e2e-api` job for
-# why this is one job (not two-jobs-sharing-name) and the 2026-04-29
-# PR #2264 incident that drove the consolidation.
-#
-# Parallel-safety (Class B Hongming-owned CICD red sweep, 2026-05-08)
-# -------------------------------------------------------------------
-# Same substrate hazard as PR #98 (handlers-postgres-integration). Our
-# Gitea act_runner runs with `container.network: host` (operator host
-# `/opt/molecule/runners/config.yaml`), which means:
-#
-#   * Two concurrent runs both try to bind their `-p 15432:5432` /
-#     `-p 16379:6379` host ports — the second postgres/redis FATALs
-#     with `Address in use` and `docker run` returns exit 125 with
-#     `Conflict. The container name "/molecule-ci-postgres" is already
-#     in use by container ...`. Verified in run a7/2727 on 2026-05-07.
-#   * The fixed container names `molecule-ci-postgres` / `-redis` (the
-#     pre-fix shape) collide on name AS WELL AS port. The cleanup-with-
-#     `docker rm -f` at the start of the second job KILLS the first
-#     job's still-running postgres/redis.
-#
-# Fix shape (mirrors PR #98's bridge-net pattern, adapted because
-# platform-server is a Go binary on the host, not a containerised
-# step):
-#
-#   1. Unique container names per run:
-#         pg-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
-#         redis-e2e-api-${RUN_ID}-${RUN_ATTEMPT}
-#      `${RUN_ID}-${RUN_ATTEMPT}` is unique even across reruns of the
-#      same run_id.
-#   2. Ephemeral host port per run (`-p 0:5432`), then read the actual
-#      bound port via `docker port` and export DATABASE_URL/REDIS_URL
-#      pointing at it. No fixed host-port → no port collision.
-#   3. `127.0.0.1` (NOT `localhost`) in URLs — IPv6 first-resolve was
-#      the original flake fixed in #92 and the script's still IPv6-
-#      enabled.
-#   4. `if: always()` cleanup so containers don't leak when test steps
-#      fail.
-#
-# Issue #94 items #2 + #3 (also fixed here):
-#   * Pre-pull `alpine:latest` so the platform-server's provisioner
-#     (`internal/handlers/container_files.go`) can stand up its
-#     ephemeral token-write helper without a daemon.io round-trip.
-#   * Create `molecule-core-net` bridge network if missing so the
-#     provisioner's container.HostConfig {NetworkMode: ...} attach
-#     succeeds.
-# Item #1 (timeouts) — evidence on recent runs (77/3191, ae/4270, 0e/
-# 2318) shows Postgres ready in 3s, Redis in 1s, Platform in 1s when
-# they DO come up. Timeouts are not the bottleneck; not bumped.
-#
-# Item explicitly NOT fixed here: failing test `Status back online`
-# fails because the platform's langgraph workspace template image
-# (ghcr.io/molecule-ai/workspace-template-langgraph:latest) returns
-# 403 Forbidden post-2026-05-06 GitHub org suspension. That is a
-# template-registry resolution issue (ADR-002 / local-build mode) and
-# belongs in a separate change that touches workspace-server, not
-# this workflow file.

-name: E2E Staging External Runtime

-# 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.

-# 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)

-name: Handlers Postgres Integration

-# 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).

-name: Railway pin audit (drift detection)
-
-# Daily audit of Railway env vars for drift-prone image-tag pins —
-# automation-cadence layer over the detection script + regression test
-# shipped in PR #2168 (#2001 closure).
-#
-# Background: on 2026-04-24 a stale `:staging-a14cf86` SHA pin in CP's
-# TENANT_IMAGE caused 3+ hours of E2E failure with the appearance that
-# "every fix didn't propagate" — really the tenant image was so old it
-# didn't read the env vars those fixes produced. The audit script
-# (scripts/ops/audit-railway-sha-pins.sh) flags drift; this workflow
-# runs the same check unattended on a daily cron.
-#
-# Cadence: once a day, 13:00 UTC (06:00 PT). Daily is the right
-# cadence for variables-tier config — Railway env var changes are
-# deliberate operator actions, low-frequency. Hourly would risk
-# Railway API rate-limit surprises and is overkill for the change rate.
-#
-# Issue-on-failure: drift triggers a priority-high issue, mirroring
-# .github/workflows/e2e-staging-sanity.yml's pattern. Drift is
-# medium-priority "config slipped, fix at next ops window," not
-# active-outage paging.
-#
-# Secret hardening: per feedback_schedule_vs_dispatch_secrets_hardening,
-# the schedule trigger HARD-FAILS on missing RAILWAY_AUDIT_TOKEN
-# (silent-success on schedule was the failure-mode class that bit the
-# team before; cron firing without checking anything is worse than no
-# cron). The workflow_dispatch trigger SOFT-SKIPS on missing secret so
-# an operator can dry-run the workflow shape during initial provisioning
-# without tripping a fake red.

-# Companion to `runtime-pin-compat.yml`. That workflow tests what's

-# 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

-#
-# By building from the PR's source and smoke-importing THAT wheel, we
-# fail at PR-time instead of after publish.

-# Required-check shape (2026-05-01): the workflow runs on EVERY push +

-# job named `PR-built wheel + import smoke`. PRs that don't touch
-# wheel-relevant paths get a no-op SUCCESS check run, satisfying branch
-# protection without re-running the heavy build. Same pattern as

-#
-# 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.

-# we don't broaden the prod-CP policy.

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

-# Janitor for Cloudflare Tunnels whose backing tenant no longer
-# exists. Parallel-shape to sweep-cf-orphans.yml (which sweeps DNS
-# records); same justification, different CF resource.
-#
-# Why this exists separately from sweep-cf-orphans:
-#   - DNS records live on the zone (`/zones/<id>/dns_records`).
-#   - Tunnels live on the account (`/accounts/<id>/cfd_tunnel`).
-#   - Different CF API surface, different scopes; the existing CF
-#     token might not have `account:cloudflare_tunnel:edit`. Splitting
-#     the workflows keeps each one's secret-presence gate independent
-#     so neither silent-skips when the other's secret is missing.
-#   - Cleaner blast radius — operators can disable one without the
-#     other if a regression surfaces.
-#
-# Safety: the script's MAX_DELETE_PCT gate (default 90% — higher than
-# the DNS sweep's 50% because tenant-shaped tunnels are mostly
-# orphans by design) refuses to nuke past the threshold.

-# Janitor for staging tenants left behind when E2E cleanup didn't run:
-# 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-

+   * the container down and back up. That kills in-flight tool subprocesses
+   * (e.g. `bash -c 'sleep 600'`) but is heavy and discards any in-progress
+   * agent state. It also bypasses the runtime-side fast cancel path (task
+   * #377 PR#40 in template-claude-code) - meaning flipping
+   * `MOLECULE_STOP_PROPAGATE=true` would produce zero canary signal because
+   * nothing ever invokes `executor.cancel()` in production.
+   *
+   * AFTER this PR (two-phase polite cancel):
+   *
+   * 1. POST `tasks/cancel` (A2A JSON-RPC) to each active workspace's
+   *    `/workspaces/:id/a2a` proxy. The platform proxies the envelope to
+   *    the workspace runtime; the a2a-sdk framework dispatches `tasks/cancel`
+   *    to `AgentExecutor.cancel()` (a2a-sdk 1.0.3
+   *    `a2a/compat/v0_3/types.py` line 1125 pins the wire literal as
+   *    `Literal["tasks/cancel"]`; A2A protocol spec section 9.4.5 maps the
+   *    abstract `CancelTask` operation to that wire string). The runtime's
+   *    executor cancel path signals the CLI subprocess group with
+   *    SIGTERM/grace/SIGKILL (template-claude-code PR#40 `stop_propagate.py`).
+   *
+   * 2. Poll the canvas store (the platform pushes `TASK_UPDATED` over WS
+   *    on `active_tasks` changes - `canvas-events.ts` line 400) for up to
+   *    `STOP_ALL_DRAIN_TIMEOUT_MS`. A workspace whose `activeTasks` drops
+   *    to 0 is considered drained and is NOT restarted.
+   *
+   * 3. For any workspace that DID NOT drain inside the timeout - runtime
+   *    is on an old image without the cancel path, or the cancel
+   *    propagation is stuck - fall back to the original heavy
+   *    `/workspaces/:id/restart`. The original behavior is preserved as a
+   *    floor so a stuck workspace still gets stopped; the polite path is
+   *    a fast top-up that lets well-behaved workspaces cancel without
+   *    losing context.
+   *
+   * The polite-cancel envelope mirrors `ScheduleTab.handleRunNow` (line 168)
+   * which is the only other place in canvas that POSTs `/workspaces/:id/a2a`
+   * directly. Method string `tasks/cancel` and empty `params` match the
+   * a2a-sdk shape verified above. The proxy adds `jsonrpc:"2.0"` and `id`
+   * via `normalizeA2APayload` server-side, so the canvas envelope omits them.

+// Package audit emits structured, single-line JSON audit-log records for

+// create/delete, A2A send, chat turn, …). Records ship to Loki via the
+// tenant Vector pipeline using two transports, in this order:
+//
+//  1. A `audit:` prefixed line on the standard logger. This is the
+//     primary transport — tenant Vector already tails the
+//     molecule-tenant container's stdout (see
+//     /usr/local/bin/tenant-vector.yaml.tmpl on operator-host), so the
+//     event reaches Loki with no Vector-side change.
+//
+//  2. A best-effort append to /var/log/molecule-audit.jsonl on the
+//     tenant container's writable rootfs. This is the durable local
+//     artifact for forensic queries when Loki is unreachable, and is
+//     the future file-source target for Phase 2 (RFC internal#562 Step
+//     1, dedicated audit shipping channel).
+//
+// Both transports are best-effort and run on the request goroutine.
+// Per RFC: emit MUST NOT fail the user's request. Any I/O error is
+// dropped to a single log.Printf line so an operator can detect the
+// outage during a forensic search. The handler caller is decoupled —
