fix(ci): add explicit utf-8 encoding to Python open() calls

Python 3's open() default encoding is platform-dependent (PEP 597).
On CI runners it happens to be UTF-8, but being explicit avoids
surprises on Windows dev boxes or custom runner images.

Files touched:
- sop-checklist.py: config loading (YAML + minimal parser)
- tests/_review_check_fixture.py: test fixture scenario loader
- tests/_refire_fixture.py: test fixture scenario loader

+# ci-arm64-advisory — Mac arm64 self-hosted ADVISORY fast-check lane.
+#
+# === WHY ===
+#
+# The amd64 Gitea runner pool (molecule-runner-1..20) is queue-contended
+# (internal#418). This lane offloads the *genuinely container-independent*
+# fast checks (Go build/vet/lint, shellcheck, Python lint) onto the Mac
+# arm64 self-hosted runner so developers get a fast arm64 signal WITHOUT
+# adding load to the starved amd64 pool — capability-honestly, as an
+# additive pilot. Pilot ② of the Mac-CI strategy (CTO-delegated 2026-05-17).
+#
+# === NON-NEGOTIABLE SAFETY CONTRACT (the prime directive) ===
+#
+# This lane is **ADVISORY ONLY**. It is provably incapable of hanging a
+# merge. Concretely:
+#
+#   1. It is a SEPARATE workflow file. `ci.yml` is byte-for-byte
+#      untouched by this PR. The `CI / all-required` aggregator sentinel
+#      and the five contexts it polls
+#      (`CI / Detect changes|Platform (Go)|Canvas (Next.js)|
+#      Shellcheck (E2E scripts)|Python Lint & Test (pull_request)`)
+#      are unchanged. The canonical required gate stays 100% on the
+#      existing amd64 pool.
+#
+#   2. The context this workflow emits is
+#      `ci-arm64-advisory / fast-checks (pull_request)`. That string is
+#      DELIBERATELY NOT present in, and this PR does NOT add it to:
+#        - branch_protections/{main,staging}.status_check_contexts
+#          (DB-verified pb 86/75 = exactly
+#           ["CI / all-required (pull_request)",
+#            "sop-checklist / all-items-acked (pull_request)"])
+#        - audit-force-merge.yml REQUIRED_CHECKS env
+#        - ci.yml `all-required` sentinel's hardcoded `required[]` list
+#      Branch protection therefore never waits on this context. If the
+#      Mac runner is absent / offline / removed, this workflow's status
+#      simply never appears — and because nothing requires it, every
+#      merge proceeds exactly as it does today. There is no path by
+#      which a missing/red arm64 status blocks a merge.
+#
+#   3. `continue-on-error: true` on the job — even a genuine arm64-only
+#      failure (toolchain drift, arch-specific test flake) is surfaced
+#      as information, never as a merge blocker, for the duration of
+#      the pilot.
+#
+#   4. The job carries a `github.event_name` `if:` gate. Beyond its
+#      functional purpose this also keeps the job OUT of
+#      `ci-required-drift.py:ci_job_names()` (which excludes
+#      `github.event_name`/`github.ref`-gated jobs), so the hourly
+#      ci-required-drift sentinel's F1 ("job not under sentinel needs")
+#      cannot ever flag this advisory job. F2/F3 are untouched because
+#      this context is absent from BP and from REQUIRED_CHECKS.
+#      `lint-bp-context-emit-match` only fails on BP→emitter gaps; an
+#      emitter without a BP context is explicitly informational there.
+#
+# === RUNNER TARGETING ===
+#
+# The Mac runner is `hongming-pc-runner-1`. The bare `self-hosted`
+# label is POLLUTED in this Gitea instance: molecule-runner-1..20
+# (the contended amd64 pool) also advertise `self-hosted`. Targeting
+# bare `self-hosted` would route back onto the very pool we are trying
+# to relieve — and onto amd64 hardware. We therefore require an
+# AND-set of labels that ONLY the Mac satisfies. `macos-self-hosted`
+# is Mac-exclusive (the amd64 pool does not carry it). Until the
+# label-install burst (a10862b2) lands `self-hosted`+`macos-self-hosted`
+# on the Mac, the runner's current unique label `hongming-pc-laptop`
+# is also listed; AND-semantics over the labels a runner advertises
+# means a job requiring [self-hosted, macos-self-hosted] can ONLY be
+# claimed once the Mac advertises both. If neither label set is yet
+# present on the Mac, the workflow stays queued harmlessly and is
+# garbage-collected by the normal stale-run reaper — it blocks nothing
+# (see safety contract point 2).
+#
+# === ROLLBACK ===
+#
+# Delete this single file (`git rm .gitea/workflows/ci-arm64-advisory.yml`)
+# and merge. No branch-protection edit, no ci.yml edit, no
+# REQUIRED_CHECKS edit is required to roll back, because none were made
+# to roll forward. Zero blast radius either direction.

-# Regression test for molecule-ai-workspace-runtime#61:

-# when stdout is a regular file (openclaw capture, CI tee, debugging).
-#
-# This workflow reproduces the exact failure mode and verifies the
-# fallback to direct buffer I/O works. It runs on every PR that

-#
-# Why a separate workflow (not folded into ci.yml python-lint):
-#   - The test needs to spawn the MCP server with stdout redirected
-#     to a regular file (not a TTY/pipe), which conflicts with
-#     pytest's own capture mechanism.
-#   - It exercises the actual process spawn path (python a2a_mcp_server.py)
-#     not just unit-test mocks — closer to the real openclaw integration.
-#   - A dedicated workflow surfaces stdio-specific regressions without
-#     coupling to the broader Python test suite's coverage gate.

-    # Three properties of this job each close a failure mode:
+    # This job deliberately has no `needs:`. Gitea 1.22/act_runner can mark a
+    # job-level `if: always()` + `needs:` sentinel as skipped before upstream
+    # jobs settle, leaving branch protection with a permanent pending
+    # `CI / all-required` context. Instead, this independent sentinel polls the
+    # required commit-status contexts for this SHA and fails if any fail, skip,
+    # or never emit. It runs the same path detector as `changes` and only waits
+    # for path-relevant jobs; Gitea can otherwise leave needs/output-skipped
+    # jobs permanently pending with "Blocked by required conditions". It runs on
+    # the dedicated `ci-meta` lane so the poller does not occupy the same
+    # general runner pool as the jobs it is waiting for.

-    #  1. `if: always()` — runs even when an upstream fails. Without it the
-    #     sentinel is `skipped` and protection treats that as missing → merge

+# Comprehensive Playwright E2E for the unified chat stack (desktop

+# outside the normal required PR path: PRs run it only after entering the
+# `merge-queue`, while push/main, nightly, and manual dispatch preserve
+# coverage without making every PR pay the full runtime/browser cost.
+#
+# Architecture:
+#   1. Ephemeral Postgres + Redis (docker, unique container names)
+#   2. workspace-server built from source, started with
+#      MOLECULE_ENV=development (fail-open auth)
+#   3. canvas dev server (npm run dev) on :3000
+#   4. Playwright tests create workspaces via API, point them at an
+#      in-process echo runtime, and exercise the full send/receive
+#      round-trip through the browser.
+#
+# Parallel-safety: same pattern as e2e-api.yml — per-run container names
+# and ephemeral host ports so concurrent jobs on the host-network runner

+name: E2E Peer Visibility (literal MCP list_peers)
+
+# WHY A DEDICATED WORKFLOW (not folded into e2e-staging-saas.yml)
+# --------------------------------------------------------------
+# This is the systemic fix for a real trust failure. Hermes and OpenClaw
+# were reported "fleet-verified / cascade-complete" because the *proxy*
+# signals were green (registry registration + heartbeat for Hermes; model
+# round-trip 200 for OpenClaw). A freshly-provisioned workspace asked on
+# canvas "can you see your peers" actually FAILS:
+#   - Hermes: 401 on the molecule MCP `list_peers` call
+#   - OpenClaw: native `sessions_list` fallback, sees no platform peers
+# Tasks #142/#159 were even marked "completed" under this proxy flaw.
+#
+# A dedicated workflow (vs extending e2e-staging-saas.yml) because:
+#   - It must provision MULTIPLE distinct runtimes (hermes, openclaw,
+#     claude-code) in ONE org and assert each sees the others. The
+#     full-saas script is single-runtime-per-run (E2E_RUNTIME) and folding
+#     a multi-runtime matrix into it would conflate concerns and bloat its
+#     already-45-min run.
+#   - It needs its own concurrency group so it doesn't fight full-saas /
+#     canvas for the staging org-creation quota.
+#   - It needs an independent, non-required status-context name so it can
+#     be RED today (the in-flight Hermes-401 / OpenClaw-MCP-wiring fixes
+#     have not landed) WITHOUT wedging unrelated merges — and flipped to
+#     REQUIRED in one branch-protection edit once it goes green
+#     (flip-to-required checklist: molecule-core#1296).
+#
+# THE ASSERTION IS NOT A PROXY. The driving script
+# tests/e2e/test_peer_visibility_mcp_staging.sh issues the byte-for-byte
+# JSON-RPC `tools/call name=list_peers` envelope to `POST
+# /workspaces/:id/mcp` using each workspace's OWN bearer token, through
+# the real WorkspaceAuth + MCPRateLimiter middleware chain — the exact
+# call mcp_molecule_list_peers makes from a canvas agent. It does NOT
+# read a registry row, /health, the heartbeat table, or
+# GET /registry/:id/peers.
+#
+# HONEST GATE — NO continue-on-error. Per feedback_fix_root_not_symptom a
+# fake-green mask would defeat the entire purpose. This workflow goes red
+# on today's broken behavior and green only when the root-cause fixes
+# actually land. It is intentionally NOT in branch_protections — see PR
+# body for the required-vs-not decision + flip tracking issue.
+#
+# Gitea 1.22.6 / act_runner notes honored:
+#   - No cross-repo `uses:` (feedback_gitea_cross_repo_uses_blocked). The
+#     actions/checkout SHA is the one e2e-staging-canvas.yml already uses
+#     successfully (a mirrored SHA — see #1277/PR#1292 root-cause).
+#   - 2026-05-21 retrigger: verify fresh platform-tenant image after the
+#     publish Buildx DOCKER_CONFIG fix restored staging-latest image updates.
+#   - Per-SHA concurrency, not global (feedback_concurrency_group_per_sha).
+#   - Workflow-level GITHUB_SERVER_URL pinned
+#     (feedback_act_runner_github_server_url).
+#   - pr-validate posts a status under the same check name so a
+#     workflow-only PR is not silently statusless and the context is
+#     flip-to-required-ready (mirrors e2e-staging-saas.yml's proven shape;
+#     real EC2-provisioning E2E is push/dispatch/cron only — it is 30+ min
+#     and cannot run per-PR-update).
+#
+# LOCAL BACKEND (added 2026-05-15 — feedback_local_must_mimic_production,
+# feedback_mandatory_local_e2e_before_ship, feedback_local_test_before_
+# staging_e2e)
+# --------------------------------------------------------------------
+# The standing rule is that the local prod-mimic stack runs a MANDATORY
+# local-Postgres E2E BEFORE staging E2E. A staging-only peer-visibility
+# gate caught regressions late + expensively (cold EC2). The
+# `peer-visibility-local` job below runs the SAME byte-identical
+# assertion (tests/e2e/lib/peer_visibility_assert.sh) against the local
+# docker-compose stack — built + booted exactly like e2e-api.yml's
+# proven E2E API Smoke Test job (ephemeral pg/redis ports, go build,
+# background platform-server). It runs on PR + push (local boot is
+# minutes, not the 30+ min cold-EC2 path), so peer-visibility is part of
+# the local gate that fires before the staging E2E.
+#
+# It is its OWN non-required status context `E2E Peer Visibility (local)`.
+# The local backend uses external-mode workspaces by default so it tests
+# the literal platform MCP list_peers path without depending on local
+# template container boot/heartbeat. Container-mode runtime boot remains
+# available via PV_LOCAL_PROVISION_MODE=container for targeted debugging.

+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.

-# Why this file exists (issue #351):
-#   Gitea Actions does not correctly disambiguate `paths:` from `tags:`
-#   when both are bundled under a single `on.push` key. The result is
-#   that tag pushes get filtered out and `publish-runtime.yml` never
-#   fires — `action_run` rows: 0. This was unnoticed pre-2026-05-11
-#   because PYPI_TOKEN was absent (publishes would have failed anyway).
-#
-#   Split design:
-#     - publish-runtime.yml         : on.push.tags only        (the publisher)
-#     - publish-runtime-autobump.yml: on.push.branches+paths   (this file — the version-bumper)
-#
-#   This file computes the next version from PyPI's latest, pushes a
-#   `runtime-v$VERSION` tag, and exits. The tag push then triggers
-#   publish-runtime.yml via its tags-only trigger.
-#
-# Concurrency: shares the `publish-runtime` group with publish-runtime.yml
-# so concurrent workspace pushes serialize at the bump step. Without

-# 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.

 # 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.

-name: canary-verify
-
-# 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.
-#
-# 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 canary-verify 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 CANARY_TENANT_URLS / CANARY_ADMIN_TOKENS /
-#     CANARY_CP_SHARED_SECRET are populated.

-# Structural gate: TEMPLATES list in publish-runtime.yml must match

-# Why a gate, not just discipline: PR #2536 pruned the manifest, but the

-# rebuilt on a runtime publish. A structural gate catches the drift
-# the same day either file changes.
-#
-# Triggers narrowly to keep CI quiet: only on PRs that actually change
-# one of the two files. The path-filtered split + always-emit-result
-# pattern (memory: "Required check names need a job that always runs")
-# is unnecessary here because the workflow IS the check name and PR
-# branch protection should require it directly. Future-proof: if this
-# becomes a required check, add a no-op aggregator with always() so the
-# name still emits when paths don't match.

-# 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.

-# 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.

-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).

-#
-# 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.

-# the schedule trigger HARD-FAILS on missing RAILWAY_AUDIT_TOKEN
-# (silent-success on schedule was the failure-mode class that bit the

-
-# 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 canary-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.

-# 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 canary-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.

-# 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.
-#
-# 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 +
-# PR + merge_group event with no top-level `paths:` filter, then uses a
-# detect-changes job + per-step `if:` gates inside ONE always-running
-# 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
-# e2e-api.yml — see its comment for the full rationale + the 2026-04-29

-#   - The proper fix (KindSecretsManagerSecret + recorder hook +

-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 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-
-# 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.

+### Workspace runtime SSOT
+
+Runtime code lives in
+[`molecule-ai-workspace-runtime`](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-runtime).
+Do not reintroduce `molecule-core/workspace/` or vendored `molecule_runtime/`
+copies in consumers. Core and templates consume the published runtime package
+from the Gitea package registry.
+
+For local external MCP agents, multi-workspace config is
+`MOLECULE_WORKSPACES=[{"id":"...","token":"...","platform_url":"..."}]`.
+`platform_url` selects the tenant; `org_id` is not part of this config.
+Workspace IDs can differ across orgs.
