auto-sync-main-to-staging.yml hasn't fired since 2026-04-29 despite
multiple staging→main promotes since. The promote PR #2442 (Phase 2)
has been wedged on `mergeStateStatus: BEHIND` for hours because
staging is missing the merge commit from PR #2437.
Three compounding bugs, all fixed here:
1. **GitHub no-recursion suppresses the `on: push` trigger.**
When the merge queue lands a staging→main promote, the resulting
push to main is "by GITHUB_TOKEN", and per
https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow
that push event does NOT fire any downstream workflows. Verified
empirically against SHA 76c604fb (PR #2437): exactly ONE workflow
fired on that push — `publish-workspace-server-image`, dispatched
explicitly by auto-promote-staging.yml's polling tail with an App
token (the documented #2357 workaround). Every other `on: push`
workflow on main, including auto-sync, was silently suppressed.
Same fix extended here: auto-promote-staging.yml's polling tail
now ALSO dispatches `auto-sync-main-to-staging.yml --ref main`
via the App token after the merge lands. App-initiated dispatch
propagates `workflow_run` cascades, which is what the publish
tail relies on too. Failure path: emits `::error::` with the
recovery command — operator runs it once and the next promote
self-heals.
auto-sync.yml gains `workflow_dispatch:` so it can be invoked
from the dispatch above + manually if a future promote also
misses (defense in depth).
2. **`runs-on: [self-hosted, macos, arm64]` was wrong for this repo.**
Comment claimed "matches the rest of this repo's workflows" — false:
this is the ONLY workflow in molecule-core/.github/workflows/ with
a non-ubuntu runs-on. Copy-paste artefact from molecule-controlplane
(which IS private and has a Mac runner). molecule-core has no Mac
runner registered, so even when the trigger DID fire (the 3 historic
manual-UI merges), the job would have sat unassigned if the runner
were offline. Switched to `ubuntu-latest` to match every other
workflow in this repo.
3. **The `on: push` trigger remains** as a defense-in-depth path for
the rare case of a manual UI merge by a real user (which uses
their PAT and DOES fire downstream workflows — confirmed via the
2026-04-29 d35a2420 run with `triggering_actor=HongmingWang-Rabbit`
that fired 16 workflows including auto-sync). Belt-and-suspenders.
Long-term: switching auto-promote's `gh pr merge --auto` call to use
the App token (instead of GITHUB_TOKEN) would let `on: push` triggers
fire naturally and obviate the need for the explicit dispatches in
the polling tail. Tracked in #2357 — out of scope here.
Operator recovery for the current Phase 2 wedge: after this lands on
staging, dispatch auto-sync once via
`gh workflow run auto-sync-main-to-staging.yml --ref main` to
backfill the missed sync from 76c604fb. PR #2442 will go from
BEHIND → CLEAN and auto-merge.

Brings the local harness from "single tenant covering the request path"
to "two tenants covering both the request path AND the per-tenant
isolation boundary" — the same shape production runs (one EC2 + one
Postgres + one MOLECULE_ORG_ID per tenant).
Why this matters: the four prior replays exercise the SaaS request
path against one tenant. They cannot prove that TenantGuard rejects
a misrouted request (production CF tunnel + AWS LB are the failure
surface), nor that two tenants doing legitimate work in parallel
keep their `activity_logs` / `workspaces` / connection-pool state
partitioned. Both are real bug classes — TenantGuard allowlist drift
shipped #2398, lib/pq prepared-statement cache collision is documented
as an org-wide hazard.
What changed:
1. compose.yml — split into two tenants.
tenant-alpha + postgres-alpha + tenant-beta + postgres-beta + the
shared cp-stub, redis, cf-proxy. Each tenant gets a distinct
ADMIN_TOKEN + MOLECULE_ORG_ID and its own Postgres database. cf-proxy
depends on both tenants becoming healthy.
2. cf-proxy/nginx.conf — Host-header → tenant routing.
`map $host $tenant_upstream` resolves the right backend per request.
Required `resolver 127.0.0.11 valid=30s ipv6=off;` because nginx
needs an explicit DNS resolver to use a variable in `proxy_pass`
(literal hostnames resolve once at startup; variables resolve per
request — without the resolver nginx fails closed with 502).
`server_name` lists both tenants + the legacy alias so unknown Host
headers don't silently route to a default and mask routing bugs.
3. _curl.sh — per-tenant + cross-tenant-negative helpers.
`curl_alpha_admin` / `curl_beta_admin` set the right
Host + Authorization + X-Molecule-Org-Id triple.
`curl_alpha_creds_at_beta` / `curl_beta_creds_at_alpha` exist
precisely to make WRONG requests (replays use them to assert
TenantGuard rejects). `psql_exec_alpha` / `psql_exec_beta` shell out
per-tenant Postgres exec. Legacy aliases (`curl_admin`, `psql_exec`)
keep the four pre-Phase-2 replays working without edits.
4. seed.sh — registers parent+child workspaces in BOTH tenants.
Captures server-generated IDs via `jq -r '.id'` (POST /workspaces
ignores body.id, so the older client-side mint silently desynced
from the workspaces table and broke FK-dependent replays). Stashes
`ALPHA_PARENT_ID` / `ALPHA_CHILD_ID` / `BETA_PARENT_ID` /
`BETA_CHILD_ID` to .seed.env, plus legacy `ALPHA_ID` / `BETA_ID`
aliases for backwards compat with chat-history / channel-envelope.
5. New replays.
tenant-isolation.sh (13 assertions) — TenantGuard 404s any request
whose X-Molecule-Org-Id doesn't match the container's
MOLECULE_ORG_ID. Asserts the 404 body has zero
tenant/org/forbidden/denied keywords (existence of a tenant must
not be probable from the outside). Covers cross-tenant routing
misconfigure + allowlist drift + missing-org-header.
per-tenant-independence.sh (12 assertions) — both tenants seed
activity_logs in parallel with distinct row counts (3 vs 5) and
confirm each tenant's history endpoint returns exactly its own
counts. Then a concurrent INSERT race (10 rows per tenant in
parallel via `&` + wait) catches shared-pool corruption +
prepared-statement cache poisoning + redis cross-keyspace bleed.
6. Bug fix: down.sh + dump-logs SECRETS_ENCRYPTION_KEY validation.
`docker compose down -v` validates the entire compose file even
though it doesn't read the env. up.sh generates a per-run key into
its own shell — down.sh runs in a fresh shell that wouldn't see it,
so without a placeholder `compose down` exited non-zero before
removing volumes. Workspaces silently leaked into the next
./up.sh + seed.sh boot. Caught when tenant-isolation.sh F1/F2 saw
3× duplicate alpha-parent rows accumulated across three prior runs.
Same fix applied to the workflow's dump-logs step.
7. requirements.txt — pin molecule-ai-workspace-runtime>=0.1.78.
channel-envelope-trust-boundary.sh imports from `molecule_runtime.*`
(the wheel-rewritten path) so it catches the failure mode where
the wheel build silently strips a fix that unit tests on local
source still pass. CI was failing this replay because the wheel
wasn't installed — caught in the staging push run from #2492.
8. .github/workflows/harness-replays.yml — Phase 2 plumbing.
* Removed /etc/hosts step (Host-header path eliminated the need;
scripts already source _curl.sh).
* Updated dump-logs to reference the new service names
(tenant-alpha + tenant-beta + postgres-alpha + postgres-beta).
* Added SECRETS_ENCRYPTION_KEY placeholder env on the dump step.
Verified: ./run-all-replays.sh from a clean state — 6/6 passed
(buildinfo-stale-image, channel-envelope-trust-boundary, chat-history,
peer-discovery-404, per-tenant-independence, tenant-isolation).
Roadmap section updated: Phase 2 marked shipped. Phase 3 promoted to
"replace cp-stub with real molecule-controlplane Docker build + env
coherence lint."

The previous header said `unittest discover from the scripts/ root
walks recursively`, contradicting the workflow body which runs two
passes precisely because discover does NOT recurse without
__init__.py. Fixed self-review feedback on PR #2440.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two small follow-ups to the PR #2433 → #2436 → #2439 incident chain.
1) `import inbox # noqa: F401` in workspace/a2a_mcp_server.py was
misleading — `inbox` IS used (at the bridge wiring inside main()).
F401 means "imported but unused", which would mask a real future
F401 if the usage is removed. Drop the noqa, keep the explanatory
block comment about the rewriter's `import X` → `import mr.X as X`
expansion (and the `import X as Y` → `import mr.X as X as Y` trap
the comment exists to prevent re-introducing).
2) scripts/test_build_runtime_package.py — 17 unit tests covering
`rewrite_imports()` and `build_import_rewriter()` in
scripts/build_runtime_package.py. Until now the function had zero
coverage despite the entire wheel build depending on it. Tests
pin: bare-import aliasing, dotted-import preservation, indented
imports, from-imports (simple + dotted + multi-symbol + block),
the `import X as Y` rejection added in PR #2436 (with comment-
stripping + indented + comma-not-alias edge cases), allowlist
anchoring (`a2a` ≠ `a2a_tools`), and end-to-end reproduction
of the PR #2433 failing pattern + the #2436 fix pattern.
3) Wire scripts/test_*.py into CI by adding a second discover pass
to test-ops-scripts.yml. Top-level scripts/ tests live alongside
their target file (parallels the scripts/ops/ test layout); the
existing scripts/ops/ pass keeps running because scripts/ops/
has no __init__.py so a single discover from scripts/ root
doesn't recurse. Two passes is simpler than retrofitting
namespace packages. Path filter widened from `scripts/ops/**`
to `scripts/**` so PRs touching the build script trigger the
new tests.

The `PR-built wheel + import smoke` gate caught the broken wheel from
PR #2433 (`import inbox as _inbox_module` collision) but couldn't block
the merge because it isn't a required check on staging. Promoting it to
required is the right move per the runtime publish pipeline gates note
(2026-04-27 RuntimeCapabilities ImportError outage), but the existing
`paths: [workspace/**, scripts/...]` filter blocks PRs that don't touch
those paths from ever generating the check run — branch protection
would deadlock waiting on a check that never fires.
Refactor (same shape as e2e-api.yml's e2e-api job):
- Drop top-level `paths:` filter — workflow runs on every push/PR/
merge_group event.
- Add `detect-changes` job using dorny/paths-filter to compute the
`wheel=true|false` output.
- Collapse to ONE always-running `local-build-install` job named
`PR-built wheel + import smoke`. Per-step `if:` gates on the
detect output. PRs untouched by wheel-relevant paths emit a
no-op SUCCESS step ("paths filter excluded this commit") so the
check passes without rebuilding the wheel.
- merge_group + workflow_dispatch unconditionally `wheel=true` so
the queue always validates the to-be-merged state, regardless of
which PR composed it.
Why one-job-with-step-gates instead of two-jobs-sharing-name: SKIPPED
check runs block branch protection even when SUCCESS siblings exist
(verified PR #2264 incident, 2026-04-29). Single always-run job emits
exactly one SUCCESS check run regardless of paths filter.
Follow-up: open a separate PR adding `PR-built wheel + import smoke`
to the staging branch protection's required_status_checks.contexts
once this lands. Doing both in one PR risks the protection update
firing before the workflow refactor merges, deadlocking unrelated PRs.

peer-discovery-404 imports workspace/a2a_client.py which depends on
httpx; the runner's stock Python doesn't have it, so the replay's
PARSE assertion (b) fails with ModuleNotFoundError on every run. The
WIRE assertion (a) — pure curl — passes, so the failure was masking
just enough to make the replay LOOK partially-broken when the tenant
side is fine.
Adding tests/harness/requirements.txt with only httpx instead of
sourcing workspace/requirements.txt: that file pulls a2a-sdk,
langchain-core, opentelemetry, sqlalchemy, temporalio, etc. — ~30s
of install for one replay's PARSE step. The harness's deps surface
should grow when a new replay introduces a new import, not by
default.
Workflow gains one step (`pip install -r tests/harness/requirements.txt`)
between the /etc/hosts setup and run-all-replays. No other changes.
First run on PR #2410 failed with 'container harness-tenant-1 is unhealthy'
but the dump-compose-logs step printed empty tenant logs because
run-all-replays.sh's trap-on-EXIT had already torn down the harness.
Setting KEEP_UP=1 leaves containers in place; the always-run Force
teardown step at the end owns cleanup explicitly. Now we'll actually
see why the tenant didn't become healthy.

Closes the gap between "the harness exists" and "the harness blocks bugs."
Phase 2 of the harness roadmap (per tests/harness/README.md): make
harness-based E2E a required CI check on every PR touching the tenant
binary or the harness itself.
Trigger: push + pull_request to staging+main, paths-filtered to
workspace-server/**, canvas/**, tests/harness/**, and this workflow.
merge_group support included so this becomes branch-protectable.
Single-job-with-conditional-steps pattern (matches e2e-api.yml). One
check run regardless of paths-filter outcome; satisfies branch
protection cleanly per the PR #2264 SKIPPED-in-set finding.
Why this exists: 2026-04-30 we shipped a TenantGuard allowlist gap
(/buildinfo added to router.go in #2398, never added to the allowlist)
that the existing buildinfo-stale-image.sh replay would have caught.
The harness was wired correctly; nobody ran it. Replays as a discipline
beat replays as a memory item.
The CI pipeline:
detect-changes (paths filter)
└ harness-replays (always)
├ no-op pass when paths-filter says no relevant change
└ otherwise: checkout + sibling plugin checkout +
/etc/hosts entry + run-all-replays.sh +
compose-logs-on-failure + force-teardown
Compose logs from tenant/cp-stub/cf-proxy/postgres are dumped on
failure so a CI red is debuggable without re-reproducing locally.
The trap in run-all-replays.sh handles teardown; the always-run
down.sh step is a belt-and-suspenders against trap-bypass kills.
Follow-ups (not in this PR):
- Add this check to staging branch protection once it's been green
for a few PRs (the new-workflow-instability hedge that other gates
followed).
- Eventually wire the buildx GHA cache to speed up tenant image
builds — currently every PR rebuilds the full Dockerfile.tenant
(Go + Next.js + template clones) from scratch. Acceptable for now;
optimize when the timeout-minutes:30 ceiling becomes painful.

publish-runtime.yml had a broad smoke (AgentCard call-shape, well-known
mount alignment, new_text_message) inline as a heredoc. runtime-prbuild-
compat.yml had a narrow inline smoke (just `from main import main_sync`).
Result: a PR could introduce SDK shape regressions that pass at PR time
and only fail at publish time, post-merge.
Extract the broad smoke into scripts/wheel_smoke.py and invoke it from
both workflows. PR-time gate now matches publish-time gate — same script,
same assertions. Eliminates the drift hazard of two heredocs that have
to be kept in lockstep manually.
Verified locally:
* Built wheel from workspace/ source, installed in venv, ran smoke → pass
* Simulated AgentCard kwarg-rename regression → smoke catches it as
`ValueError: Protocol message AgentCard has no "supported_interfaces"
field` (the exact failure mode of #2179 / supported_protocols incident)
Path filter for runtime-prbuild-compat extended to include
scripts/wheel_smoke.py so smoke-only edits get PR-validated. publish-
runtime path filter intentionally NOT extended — smoke-only edits should
not auto-trigger a PyPI version bump.
Subset of #131 (the broader "invoke main() against stub config" goal
remains pending — main() needs a config dir + stub platform server).

Self-review of #2403 caught a regression: with a 1-tenant fleet (the
exact case the original #2402 fix targeted), the new floor would
re-introduce the flake. Trace:
TOTAL=1, UNREACHABLE=1, $((1/2))=0
if 1 -gt 0 → TRUE → exit 1
The 50%-rule only meaningfully distinguishes "real outage" from
"teardown race" when the fleet is large enough that "half down" is
statistically meaningful. With 1-3 tenants, canary-verify is the
actual gate (it runs against the canary first and aborts the rollout
if the canary fails to come up).
Gate the floor on TOTAL_VERIFIED >= 4. Truth table:
TOTAL UNREACHABLE RESULT
1 1 soft-warn (original e2e flake case)
4 2 soft-warn (exactly half)
4 3 hard-fail (75% — real outage)
10 6 hard-fail (60% — real outage)
Mirrored across staging.yml + main.yml.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Belt-and-suspenders sanity floor on top of the unreachable-soft-warn
introduced earlier in this PR. Addresses the residual gap noted in
review: if a new image crashes on startup, every tenant ends up
unreachable, and the soft-warn alone would let that ship as a green
deploy. Canary-verify catches it on the canary tenant first, but this
guard is a fallback for canary-skip dispatches and same-batch races.
Threshold is 50% of healthz_ok-snapshotted tenants — comfortably above
the typical e2e-* teardown rate (5-10/hour, ~1 ephemeral tenant per
batch) but below any plausible real-outage scenario.
Mirrored across staging.yml + main.yml for shape parity.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The /buildinfo verify step (PR #2398) was treating "no /buildinfo response"
the same as "tenant returned wrong SHA" — both bumped MISMATCH_COUNT and
hard-failed the workflow. First post-merge run on staging caught a real
edge case: ephemeral E2E tenants (slug e2e-20260430-...) get torn down by
the E2E teardown trap between CP's healthz_ok snapshot and the verify step
running, so the verify step would dial into DNS that no longer resolves
and hard-fail on a benign condition.
The bug class we actually care about is STALE (tenant up + serving old
code, the #2395 root). UNREACHABLE post-redeploy is almost always a benign
teardown race; real "tenant up but unreachable" is caught by CP's own
healthz monitor + the alert pipeline, so double-counting it here was
making this workflow flaky on every staging push that overlapped E2E.
Wire:
- Split MISMATCH_COUNT into STALE_COUNT + UNREACHABLE_COUNT.
- STALE → hard-fail the workflow (the bug class we're guarding).
- UNREACHABLE → :⚠️:, don't fail. Reachable-mismatch still hard-fails.
- Job summary surfaces both lists separately so on-call can tell at a
glance which class fired.
Mirror in redeploy-tenants-on-main.yml for shape parity (prod has fewer
ephemeral tenants but identical asymmetry would be a gratuitous fork).

Closes the gap that let issue #2395 ship: redeploy-fleet workflows reported
ssm_status=Success based on SSM RPC return code alone, while EC2 tenants
silently kept serving the previous :latest digest because docker compose up
without an explicit pull is a no-op when the local tag already exists.
Wire:
- new buildinfo package exposes GitSHA, set at link time via -ldflags from
the GIT_SHA build-arg (default "dev" so test runs without ldflags fail
closed against an unset deploy)
- router exposes GET /buildinfo returning {git_sha} — public, no auth,
cheap enough to curl from CI for every tenant
- both Dockerfiles thread GIT_SHA into the Go build
- publish-workspace-server-image.yml passes GIT_SHA=github.sha for both
images
- redeploy-tenants-on-main.yml + redeploy-tenants-on-staging.yml curl each
tenant's /buildinfo after the redeploy SSM RPC and fail the workflow on
digest mismatch; staging treats both :latest and :staging-latest as
moving tags; verification is skipped only when an operator pinned a
specific tag via workflow_dispatch
Tests:
- TestGitSHA_DefaultDevSentinel pins the dev default
- TestBuildInfoEndpoint_ReturnsGitSHA pins the wire shape that the
workflow's jq lookup depends on
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
When gh run list returns [] (no E2E run on the main SHA — the common
case for canvas-only / cmd-only / sweep-only changes whose paths
don't trigger E2E), jq's `.[0]` is null and the interpolation
`"\(null)/\(null // "none")"` produces "null/none". The case
statement has no `null/none)` branch, so it falls into `*)` →
exit 1 → auto-promote-on-e2e fails → `:latest` doesn't get retagged
to the new SHA → tenants on `redeploy-tenants-on-main` end up
pulling the OLD `:latest` digest.
Surfaced 2026-04-30 17:00Z as the first observable consequence of
PR #2389 (App-token dispatch fix). Every prior auto-promote-on-e2e
run was triggered by E2E completion (the "Upstream is E2E itself"
short-circuit at line 151 fired before reaching the gate). #2389
made publish-image's completion event correctly fire workflow_run
listeners — auto-promote-on-e2e is one of those listeners — and
hit the latent jq bug on the first publish-upstream run.
Fix: change `.[0]` to `(.[0] // {})` in the jq filter so the empty-
array case becomes `none/none` (the documented "E2E paths-filtered
out for this SHA — proceed" branch) instead of the unhandled
`null/none`. Also default `.status` for the same defensive reason.
Verified the three input shapes locally:
[] → "none/none" ✓
[{status:completed,conclusion:success}] → "completed/success" ✓
[{status:in_progress,conclusion:null}] → "in_progress/none" ✓
Outer `|| echo "none/none"` fallback retained as defense-in-depth
for non-zero gh exits (network / auth failures).

Pins the four workspaces.status=awaiting_agent transitions on a real
staging tenant, end-to-end. Catches the class of silent enum failures
that migration 046 fix-forwarded — specifically:
1. workspace.go:333 — POST /workspaces with runtime=external + no URL
parks the row in 'awaiting_agent'. Pre-046 the UPDATE silently
failed and the row stuck on 'provisioning'.
2. registry.go:resolveDeliveryMode — registering an external workspace
defaults delivery_mode='poll' (PR #2382). The harness asserts the
poll default after register.
3. registry/healthsweep.go:sweepStaleRemoteWorkspaces — after
REMOTE_LIVENESS_STALE_AFTER (90s default) with no heartbeat, the
workspace transitions back to 'awaiting_agent'. Pre-046 the sweep
UPDATE silently failed and the workspace stuck on 'online' forever.
4. Re-register from awaiting_agent → 'online' confirms the state is
operator-recoverable, which is the whole reason for using
awaiting_agent (vs. 'offline') as the external-runtime stale state.
The harness mirrors test_staging_full_saas.sh: tenant create →
DNS/TLS wait → tenant token retrieve → exercise → idempotent teardown
via EXIT/INT/TERM trap. Exit codes match the documented contract
{0,1,2,3,4}; raw bash exit codes are normalized so the safety-net
sweeper doesn't open false-positive incident issues.
The companion workflow gates on the source files that touch this
lifecycle: workspace.go, registry.go, workspace_restart.go,
healthsweep.go, liveness.go, every migration, the static drift gate,
and the script + workflow themselves. Daily 07:30 UTC cron catches
infra drift on quiet days. cancel-in-progress=false because aborting
a half-rolled tenant leaves orphan resources for the safety-net to
clean.
Verification:
- bash -n: ok
- shellcheck: only the documented A && B || C pattern, identical to
test_staging_full_saas.sh.
- YAML parser: ok.
- Workflow path filter matches every site that writes to the
workspace_status enum (cross-checked against the drift gate's
UPDATE workspaces / INSERT INTO workspaces enumeration).

Root cause (verified 2026-04-30): GITHUB_TOKEN-initiated
workflow_dispatch creates the dispatched run, but the resulting run's
completion event does NOT fire downstream `workflow_run` triggers.
This is the documented "no recursion" rule:
https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow
Evidence (publish-workspace-server-image runs on main):
run_id | head_sha | triggering_actor | canary | redeploy
------------+-----------+-----------------------+--------+----------
25151545007 | 6ef562ee | HongmingWang-Rabbit | YES | YES
25171773918 | 21313dc | github-actions[bot] | NO | NO
25173801008 | 59dec57 | github-actions[bot] | NO | NO
The 06:52Z run that "worked" was an operator-fired dispatch from the
terminal — actor was the operator's PAT. The two runs that "dropped"
were dispatched by auto-promote-staging.yml's `gh workflow run` step
authenticated via `secrets.GITHUB_TOKEN`, so the actor became
`github-actions[bot]` and the workflow_run cascade was suppressed.
Same workflow file, same dispatch call, same successful publish run
— only the auth token differed.
Fix: mint a molecule-ai GitHub App installation token before the
dispatch step and use it as `GH_TOKEN`. App-initiated dispatches
DO propagate the workflow_run cascade (the App user is a real
identity, not the GITHUB_TOKEN bot pseudonym).
The molecule-ai App (app_id=3398844, installation 124443072) is
already installed on the org with `actions:write` — no new App
needed. Only secrets are missing.
## Required setup before merge
The following repo secrets must be added at
https://github.com/Molecule-AI/molecule-core/settings/secrets/actions
or auto-promote will hard-fail at the new "Mint App token" step:
- `MOLECULE_AI_APP_ID` = `3398844`
- `MOLECULE_AI_APP_PRIVATE_KEY` = contents of a .pem file generated at
https://github.com/organizations/Molecule-AI/settings/installations/124443072
(Click "Generate a private key" if one doesn't exist yet.)
## Long-term cleanup
The polling tail step still exists because the auto-merge call
itself uses GITHUB_TOKEN, so the FF push to main doesn't fire
publish-workspace-server-image's `push` trigger naturally. Switching
the auto-merge call to use the SAME App token would eliminate the
polling tail entirely. Tracked in #2357.

The check has been blocking the staging→main auto-promote PR (#2361)
since 2026-04-30T07:17Z with:
fatal: origin/main...<head>: no merge base
Root cause: the workflow does `git fetch origin <base> --depth=1`
which overwrites checkout@v4's full-history clone with a shallow
tip — destroying the ancestry the subsequent
`git diff origin/main...HEAD` (three-dot, merge-base form) needs.
This deadlocks every staging→main promote PR until manually fixed.
The auto-promote runs were succeeding at the gate-check phase but
the subsequent PR-merge step waited 30 min for the failing check
and timed out, skipping the publish + redeploy dispatch tail.
Fleet recovery for any production-only fix went through staging
fine but never reached main.
Fix: drop --depth=1 so the explicit fetch preserves full history.
The leading comment is updated to call out this trap so a future
maintainer doesn't re-add the flag thinking it's a perf win.
No test added: this is a workflow-config one-liner that the
existing PR check itself exercises end-to-end (the real signal is
PR #2361 going green after this lands).

Independent review of #2358 surfaced three gaps that the original
self-review missed. All three would manifest only on the FIRST real
staging→main promotion through the new tail step, so they'd silently
re-introduce the deploy-chain bug #2357 was supposed to fix.
1. **Missing `actions: write` permission.** `gh workflow run` POSTs to
`/repos/.../actions/workflows/.../dispatches`, which requires the
actions:write scope on GITHUB_TOKEN. The job had only contents:write
+ pull-requests:write, so the dispatch call would 403 on every run
and the publish chain would still not fire. Adding the scope.
2. **No workflow-level concurrency block.** When CI + E2E Staging
Canvas + E2E API Smoke + CodeQL all complete within seconds of each
other on a green staging push (the typical case), four separate
workflow_run events fire and four parallel auto-promote runs all
reach the dispatch tail. They poll the same PR, all observe the
same mergedAt, and all call `gh workflow run` — producing 2-4×
redundant publish builds racing for the same `:staging-latest`
retag and 2-4× canary-verify chains. Added
`concurrency.group: auto-promote-staging, cancel-in-progress: false`.
cancel-in-progress=false because killing a polling tail that's
about to dispatch would re-introduce the original bug.
3. **PR closed-without-merge ties up a runner for 30 min.** If the
merge queue rejects the PR (gates flip red post-approval), or an
operator closes it manually, mergedAt stays null forever and the
loop polls 60 × 30s burning a runner slot. Now also reads `state`
in the same `gh pr view` call and breaks early when STATE=CLOSED.
Verification on this PR is structural (workflow won't fire on a
staging→main promotion until this lands AND a subsequent staging
push triggers auto-promote). The actions:write fix in particular is
unverifiable until the next real run — the prior #2358 fix has
the same property, so we're stacking two unverifiable workflow
edits. That's intentional rather than risky: stage 1 (#2358) was
load-bearing for the deploy-chain restoration; stage 2 (this PR)
hardens it before it actually matters.

The auto-promote staging → main flow uses `gh pr merge --auto` with
GITHUB_TOKEN, which means GitHub suppresses downstream `push` events on
the resulting main commit. This is documented behavior — events created
by GITHUB_TOKEN do not trigger new workflow runs, with workflow_dispatch
and repository_dispatch as the only exceptions.
Effect: when the merge queue lands the auto-promote PR, the main push
DOES NOT fire publish-workspace-server-image. canary-verify + the
:staging-<sha> → :latest retag never run, so redeploy-tenants-on-main
also never fires. Tenants stay on stale code until someone manually
dispatches the chain (which is what just happened for issue #2339).
Fix here: after enqueuing auto-merge, poll for the PR to land, then
explicitly `gh workflow run publish-workspace-server-image.yml --ref
main`. workflow_dispatch is the documented exception, so the dispatch
event itself DOES create a new run. canary-verify and
redeploy-tenants-on-main chain via workflow_run as before.
Long-term (tracked in #2357): switch the auto-merge call above to a
GitHub App token (actions/create-github-app-token) so the merge event
itself can trigger the downstream chain naturally; the polling tail
becomes deletable.
Why a 30-min poll cap: merge queue typically lands a green promote PR
within 5-10 min. 30 min covers a slow CI run without hanging the
workflow indefinitely. If the merge times out, the step warns and
exits 0 — operator can manually dispatch as a fallback.

End-to-end coverage for the canvas-chat unblocker. Exercises every
moving part of the #2339 stack against a real platform instance:
Phase 1 — register a workspace as delivery_mode=poll WITHOUT a URL;
verify the response carries delivery_mode=poll.
Phase 2 — invalid delivery_mode rejected with 400 (typo defense).
Phase 3 — POST A2A to the poll-mode workspace; verify proxyA2ARequest
short-circuits and returns 200 {status:queued, delivery_mode:poll,
method:message/send} without ever resolving an agent URL.
Phase 4 — verify the queued message appears in /activity?type=a2a_receive
with the right method + payload (the polling agent reads from here).
Phase 5 — since_id cursor returns ASC-ordered rows STRICTLY AFTER the
cursor; the cursor row itself must NOT be replayed. Sends two
follow-up messages and asserts ordering: rows[0] is the older new
event, rows[-1] is the newer.
Phase 6 — unknown / pruned cursor returns 410 Gone with an explanation.
Phase 7 — cross-workspace cursor isolation: a UUID belonging to one
workspace cannot be used to peek at another workspace's feed (returns
410, same as pruned, no info leak).
Idempotent: per-run unique workspace ids (date+pid). Trap-based cleanup
deletes the test rows on exit; no e2e_cleanup_all_workspaces call (see
feedback_never_run_cluster_cleanup_tests_on_live_platform.md).
Wired into .github/workflows/e2e-api.yml so it runs on every PR that
touches workspace-server/, tests/e2e/, or the workflow file itself —
same gate as the existing test_a2a_e2e + test_notify_attachments suites.
Stacked on #2354 (PR 3: since_id cursor).

Hard gate Tier 2 item 2 of 4. 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.
Empirical motivation from today:
- #2345 (A2A v0.2 silent drop) — passed unit tests, broke at JSON-RPC
parse layer between sender + receiver. Visible only when a sender
exercises the full path. Now-fixed by PR #2349, but a continuous
E2E would have surfaced it within 20 min of the regression.
- RFC #2312 chat upload — landed staging-branch but never reached
staging tenants because publish-workspace-server-image was main-
only. Caught by manual dogfooding hours after deploy. Same pattern.
Both classes are invisible to PR-time CI. The continuous gate fires
every 20 min against a real staging tenant and surfaces regressions
within minutes.
Cadence: cron `0,20,40 * * * *` (3x/hour). Offsets the existing
sweep-cf-orphans (:15) and sweep-cf-tunnels (:45) so the three ops
don't burst CF/AWS APIs at the same minute. Concurrency group
prevents overlapping runs if one hangs.
Cost: ~$0.50-1/day GHA + pennies of staging tenant lifecycle.
Reuses existing tests/e2e/test_staging_full_saas.sh — no new harness
to maintain. Bounded at 10 min wall-clock (vs 15 min default) so
stuck runs fail fast rather than holding up the next firing.
Defaults to E2E_RUNTIME=langgraph (fastest cold start; the regression
classes this gate catches don't need hermes-specific paths). Operators
can dispatch with runtime=hermes when they want SDK-native coverage.
Schedule-vs-dispatch hardening: hard-fail on missing
CP_STAGING_ADMIN_API_TOKEN for cron firing (silent-skip would mask
real outages); soft-skip for operator dispatch.
Refs:
- #2342 hard-gates Tier 2 item 2
- #2345 (A2A v0.2 fix that this gate would have caught earlier)
- #2335 / #2337 (deployment-pipeline gaps that this gate also catches)
Two PRs targeting staging can each add a migration with the same
numeric prefix (e.g. 044_*.up.sql). Each passes CI independently.
They collide at merge time. Worst case: second migration silently
doesn't apply and prod schema drifts from what the code expects.
Caught manually 2026-04-30 during PR #2276 rebase: 044_runtime_image_pins
collided with 044_platform_inbound_secret from RFC #2312. This workflow
makes that detection automatic at PR-open time.
How it works:
scripts/ops/check_migration_collisions.py runs on every PR that
touches workspace-server/migrations/**. For each new/modified
migration filename, extracts the numeric prefix and checks:
1. Does the base branch already have a DIFFERENT migration file with
the same prefix? (PR branched off an old base, base advanced and
another PR landed the same number — needs rebase.)
2. Is another OPEN PR (not this one) also adding a migration with
the same prefix? (Race-window collision — both pass CI separately,
would collide at merge time.)
Either case → exit 1 with a clear ::error:: message naming the
conflicting PR(s) so the author knows what to renumber.
Implementation notes:
- Uses git ls-tree (not working-tree walk) so it works against any
base ref without checkout.
- Uses gh pr diff --name-only per open PR, bounded by `gh pr list
--limit 100`. ~30s worst case for a busy repo, <5s normally.
- --diff-filter=AM picks up Added or Modified — renaming a migration
in place is also flagged (intentional; renaming migrations isn't
safe).
- Same filename in both PR and base = no collision (PR is editing
in-place, fine).
Tests:
scripts/ops/test_check_migration_collisions.py — 9 cases on the
regex classifier (the load-bearing piece). End-to-end git/gh path
is exercised by running the workflow against real PRs.
Hard-gates Tier 1 item 1 (#2341). Cheapest, cleanest gate. Catches
one specific class of merge-time foot-gun automatically.
Refs hard-gates discussion 2026-04-30. Tier 1 of 4 (others tracked
in #2342, #2343, #2344).
Parity with #2337's redeploy-tenants-on-staging.yml. Both prod and
staging redeploys now have explicit serialization:
group: redeploy-tenants-on-main (per-workflow, global)
group: redeploy-tenants-on-staging (per-workflow, global)
cancel-in-progress: false on both — aborting a half-rolled-out fleet
would leave tenants stuck on whatever image they happened to be on
when cancelled. Better to finish the in-flight rollout before starting
the next one.
Pre-fix this workflow relied on GitHub's implicit workflow_run queueing,
which is "probably fine" but not defensible — explicit > implicit for
load-bearing pipeline behavior. Picked up as a #2337 review nit
(architecture finding 1: concurrency asymmetry between the two
redeploy workflows).
No behavior change in the common case. The change matters only when
two main pushes land within seconds AND the first redeploy is still
mid-rollout — currently rare; will become more common once #2335
(staging-trigger publish) feeds main more frequently via auto-promote.
Two follow-ups from #2335 review (tracked in #2336):
1. Add `concurrency:` block to publish-workspace-server-image.yml so
two rapid staging pushes don't race the same :staging-latest retag.
Group is per-branch (`${{ github.ref }}`) so staging and main can
build in parallel — they produce different :staging-<sha> tags and
last-write-wins on :staging-latest is acceptable across branches.
`cancel-in-progress: false` keeps in-flight builds — partially-pushed
images would break canary-fleet pin consistency.
2. Add redeploy-tenants-on-staging.yml. After #2335, every staging push
produces a fresh :staging-latest, but existing tenants only pick it
up on next reprovision. This workflow mirrors redeploy-tenants-on-
main but for staging:
- workflow_run-gated to branches: [staging]
- target_tag default 'staging-latest' (vs 'latest' for prod)
- CP_URL default https://staging-api.moleculesai.app
- CP_STAGING_ADMIN_API_TOKEN repo secret (operator must set)
- canary_slug empty by default — staging is itself the canary; no
sub-canary needed inside it. Soak still applies if operator
specifies a tenant for blast-radius control.
Schedule-vs-dispatch hardening matches sweep-cf-orphans/sweep-cf-
tunnels: hard-fail on auto-trigger when secret missing so misconfig
doesn't silently leave staging tenants on stale code; soft-skip on
operator dispatch.
Operator action required after merge:
Add CP_STAGING_ADMIN_API_TOKEN repo secret. Pull value from staging-
CP's CP_ADMIN_API_TOKEN env in Railway controlplane / staging
environment. Until set, the auto-trigger will fail the workflow run
(visible as red CI), surfacing the misconfiguration. Workflow runs
only on staging publish-workspace-server-image success, so no extra
load while it sits unconfigured.
Verification:
- YAML lint clean on both workflows.
- Reviewed redeploy-tenants-on-main as template; differences are scoped
to staging-specific values (URL, tag, secret name) + harden-on-missing-
secret pattern.
Refs #2335, #2336.
Root cause: this workflow only triggered on `branches: [main]`, but
staging-CP pins TENANT_IMAGE=:staging-latest (verified via Railway).
:staging-latest was only retagged on main push, so:
staging-branch code → never built → never reaches staging tenants
staging-CP serves → "yesterday's main" indefinitely
When staging→main was wedged (path-filter parity bug, canvas teardown
race — both fixed earlier today), :staging-latest stopped updating
entirely. RFC #2312 (chat upload HTTP-forward) landed on staging but
freshly-provisioned staging tenants kept failing chat upload because
they pulled pre-RFC-#2312 image. Verified by tearing down a fresh
tenant and observing the legacy "workspace container not running"
error from the docker-exec code path that RFC #2312 deleted.
Pre-2026-04-24 there was a related-but-different incident: TENANT_IMAGE
was a static :staging-<sha> pin that drifted 10 days behind. This new
incident is "the dynamic pin still drifts when its update workflow
doesn't fire."
Fix: add `staging` to the branches trigger. Tag policy is unchanged
(:staging-<sha> + :staging-latest on every push). canary-verify.yml
still runs on main push (workflow_run-gated to `branches: [main]`),
preserving the canary-verified :latest promotion for prod tenants.
Steady state after this:
- staging push → :staging-latest = staging-branch code → staging-CP
- main push → :staging-<sha> for canary, :staging-latest retag
(post-promote main code), and after canary green
→ :latest for prod tenants
What this does NOT change:
- canary-verify.yml flow (still main-only)
- redeploy-tenants-on-main.yml (still rolls prod fleet on main push)
- publish-canvas-image.yml (self-hosted standalone canvas; orthogonal)
- The :latest tag (canary-verified main, unchanged)
What this does fix:
- RFC #2312-class fixes that land on staging now actually reach
staging tenants without waiting for staging→main promote.
- The dogfooding observation "staging tenants seem to be running
yesterday's code" disappears as a class.
Drive-by: also fixed the typo in the path-filter list (was
`publish-platform-image.yml`, the actual file is
`publish-workspace-server-image.yml`).
CP's tenant-delete cascade removes the DNS record (with sweep-cf-orphans
as a backstop) but does NOT delete the underlying Cloudflare Tunnel.
Each E2E provision creates one Tunnel named `tenant-<slug>`; without
cleanup these accumulate indefinitely on the account, consuming the
tunnel quota and cluttering the dashboard.
Observed 2026-04-30: dozens of `tenant-e2e-canvas-*` tunnels in Down
state with zero replicas, weeks past their tenant's deletion. Same
class of bug as the DNS-records leak that drove sweep-cf-orphans
(controlplane#239).
Parallel-shape to sweep-cf-orphans:
- Same dry-run-by-default + --execute pattern
- Same MAX_DELETE_PCT safety gate (default 90% — higher than DNS
sweep's 50% because tenant-shaped tunnels are orphans by design)
- Same schedule/dispatch hardening (hard-fail on missing secrets
when scheduled, soft-skip when dispatched)
- Cron offset to :45 to avoid CF API bursts colliding with the DNS
sweep at :15
Decision rules (in order):
1. Name doesn't match `tenant-<slug>` → keep (unknown — never sweep
tunnels that might belong to platform infra).
2. Tunnel has active connections (status=healthy or non-empty
connections array) → keep (defense-in-depth: don't kill a live
tunnel even if CP forgot the org).
3. Slug ∈ {prod_slugs ∪ staging_slugs} → keep.
4. Otherwise → delete (orphan).
Verified by:
- shell syntax check (bash -n)
- YAML lint
- Decide-logic offline smoke (7 cases, all pass)
- End-to-end dry-run smoke with stubbed CP + CF APIs
Required secrets (added to existing org-secrets):
CF_API_TOKEN must include account:cloudflare_tunnel:edit
scope (separate from zone:dns:edit used by
sweep-cf-orphans — same token if scope is
broad, or a new token if narrowly scoped).
CF_ACCOUNT_ID account that owns the tunnels (visible in
dash.cloudflare.com URL path).
CP_PROD_ADMIN_TOKEN reused from sweep-cf-orphans.
CP_STAGING_ADMIN_TOKEN reused from sweep-cf-orphans.
Note: CP-side root cause (tenant-delete should cascade to tunnel
delete) is in molecule-controlplane and worth fixing separately. This
janitor is the operational backstop in the meantime — same pattern
applied to DNS records when the same root cause was unaddressed.
Setup wrote .playwright-staging-state.json at the END (step 7), only
after org create + provision-wait + TLS + workspace create + workspace-
online all succeeded. If setup crashed at steps 1-6, the org existed in
CP but the state file did not, so Playwright's globalTeardown bailed
out ("nothing to tear down") and the workflow safety-net pattern-swept
every e2e-canvas-<today>-* org to compensate. That sweep deleted
concurrent runs' live tenants — including their CF DNS records —
causing victims' next fetch to die with `getaddrinfo ENOTFOUND`.
Race observed 2026-04-30 on PR #2264 staging→main: three real-test
runs killed each other mid-test, blocking 68 commits of staging→main
promotion.
Fix: write the state file as setup's first action, right after slug
generation, before any CP call. Now:
- Crash before slug gen → no state file, no orphan to clean
- Crash during steps 1-6 → state file has slug; teardown deletes
it (DELETE 404s if org never created)
- Setup completes → state file has full state; teardown
deletes the slug
The workflow safety-net no longer pattern-sweeps; it reads the state
file and deletes only the recorded slug. Concurrent canvas-E2E runs no
longer poison each other.
Verified by:
- tsc --noEmit on staging-setup.ts + staging-teardown.ts
- YAML lint on e2e-staging-canvas.yml
- Code review: state file write moved to line 113 (post-makeSlug,
pre-CP) with the original line-249 write retained as a "promote
to full state" overwrite at the end
Acceptance criterion 3 of #2001 ("CI check that fails if TENANT_IMAGE
contains a SHA-shaped suffix") was deferred from PR #2168 because
querying Railway from a GitHub Actions runner needs RAILWAY_TOKEN
plumbed as a repo secret. The detection script + regression test in
#2168 cover detection; this is the automation-cadence layer.
Daily 13:00 UTC schedule (06:00 PT) + workflow_dispatch. 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.
Issue-on-failure pattern mirrors e2e-staging-sanity.yml — drift opens
a `railway-drift` priority-high issue (or comments on the open one),
and a subsequent clean run auto-closes it with a "drift resolved"
comment. No human-in-the-loop needed for the close.
Schedule-vs-dispatch secret hardening per
feedback_schedule_vs_dispatch_secrets_hardening:
- Schedule trigger HARD-FAILS on missing RAILWAY_AUDIT_TOKEN
(silent-success was the failure mode that bit us before)
- workflow_dispatch SOFT-SKIPS so an operator can dry-run the
workflow shape during initial token provisioning
Operator action required before this gate is live:
- Provision a Railway API token, read-only `variables` scope on the
molecule-platform project (id 7ccc8c68-61f4-42ab-9be5-586eeee11768)
- Store as repo secret RAILWAY_AUDIT_TOKEN
- Rotate per the standard 90-day schedule

Branch protection treats matching-name check runs as a SET — any SKIPPED
member fails the required-check eval, even with SUCCESS siblings. The
two-jobs-sharing-name pattern (no-op + real-job) emits one SKIPPED + one
SUCCESS check run per workflow run; with multiple runs at the same SHA
(detect-changes triggers + auto-promote re-runs) the SET fills with
SKIPPED entries that block branch protection.
Verified live on PR #2264 (staging→main auto-promote): mergeStateStatus
stayed BLOCKED for 18+ hours despite APPROVED + MERGEABLE + all gates
green at the workflow level. `gh pr merge` returned "base branch policy
prohibits the merge"; `enqueuePullRequest` returned "No merge queue
found for branch 'main'". The check-runs API showed `E2E API Smoke
Test` and `Canvas tabs E2E` each had 2 SKIPPED + 2 SUCCESS at head SHA
66142c1e.
Fix: collapse no-op + real-job into ONE job with no job-level `if:`,
gating real work via per-step `if: needs.detect-changes.outputs.X ==
'true'`. The job always runs and emits exactly one SUCCESS check run
under the required-check name regardless of paths-filter outcome —
branch-protection-clean.
Same pattern as ci.yml's earlier conversion of Canvas/Platform/Python/
Shellcheck (PR #2322). Closes the parity-fix that should have been
applied to all four path-filtered required checks at once.
Two rapid main pushes whose E2Es complete out-of-order can promote
:latest backwards: SHA-A merges, SHA-B merges, SHA-B's E2E completes
first → :latest = staging-B → SHA-A's E2E completes → :latest = staging-A.
Now :latest is older than main's tip and stays wrong until the next
main push lands. The orphan-reconciler "next run corrects it" pattern
doesn't apply because there's no auto-corrective re-promote.
Detection: read the current :latest's `org.opencontainers.image.revision`
label (set by publish-workspace-server-image.yml at build time) and ask
the GitHub compare API how the candidate SHA relates to current. Branch
on `.status`:
ahead → retag (target newer)
identical → retag is a no-op
behind → HARD FAIL (this is the race we're catching)
diverged → HARD FAIL (force-push or unusual history)
error → fail; manual dispatch can override
Hard-fail rather than soft-skip per the approved design — silent-bypass
is the class we're moving away from per
feedback_schedule_vs_dispatch_secrets_hardening. Workflow goes red,
oncall sees it, operator decides whether to retry, force-promote, or
investigate. Manual dispatch skips the check (operator override),
matching the gate-step's existing semantics.
Backward-compat: when current :latest carries no revision label
(legacy image), skip-with-warning. All :latest images on main are
post-label as of 2026-04-29, so this branch becomes dead within 90 days
— TODO note in the step explains the cleanup.
No tests — the race is hypothetical at our scale (<1 occurrence/year
expected for a fleet of ≤20 paying tenants), and the only way to
exercise the new branches is to construct production-shape image
state. The dry-fall path lands behind the existing E2E gate-check, so
a regression in this step would surface as a failed promote (visible),
not a silent advance (invisible).

Supersedes #2321 + #2322. Applies the same shape uniformly across every
required check that uses a path filter: Canvas (Next.js), Platform (Go),
Python Lint & Test, Shellcheck (E2E scripts).
The bug + fix in one paragraph:
GitHub registers a check run for every job whose `name:` matches the
required-check context, regardless of whether the job actually executed.
A job-level `if:` that evaluates false produces a SKIPPED check run.
Branch protection's "required check" rule looks at the SET of check
runs with the matching context name on the latest commit and treats
any conclusion other than SUCCESS as not-passed — including SKIPPED.
Adding a sibling no-op job under the same `name:` (PR #2321 / #2322
attempt) doesn't help: branch protection still sees the SKIPPED
sibling and stays BLOCKED.
The shape that works: ONE job per required check name, no job-level
`if:`, all real work gated per-step. The job always runs and reports
SUCCESS regardless of which paths changed.
This patch:
* Canvas (Next.js): drops the `canvas-build-noop` shadow added in
#2321 (which didn't actually clear merge state — verified live on
PR #2314). Refactors `canvas-build` to always run; gates checkout/
setup-node/install/build/test on `if: needs.changes.outputs.canvas
== 'true'`. Coverage upload step also gated.
* Platform (Go): drops job-level `if:`. Gates checkout/setup-go/
download/build/vet/lint/test/coverage-report/threshold-check on
per-step `if:`.
* Python Lint & Test: drops job-level `if:`. Gates checkout/setup-
python/install/pytest on per-step `if:`.
* Shellcheck (E2E scripts): drops job-level `if:`. Gates checkout/
shellcheck-run on per-step `if:`.
Each refactored job adds a leading no-op echo step with `working-directory: .`
override so the always-running spin-up doesn't fail when the path-
filter-true working-directory (workspace, workspace-server, canvas)
doesn't exist after no-op checkout.
Why all four in one PR: the bug shape is identical across all four,
and a future PR that only touches workspace-server (passing platform
filter, missing canvas/python/scripts) would hit the same BLOCKED state
on whichever filter it missed. PR-A and PR-2321 merged because their
diffs happened to trigger every filter; PR-B (#2314) only missed
canvas. Fixing one at a time means re-living this debugging cycle three
more times.
Cost: ~10s of always-on CI runtime per PR per job (the ubuntu-latest
spin-up + the no-op echo). 40s aggregate, negligible vs. the manual-
merge cost when BLOCKED catches us.
Memory `feedback_branch_protection_check_name_parity` already updated
(2026-04-29) to mark the original two-jobs-sharing-name pattern as
DO NOT FOLLOW and document the working shape this PR uses.
Refs PR #2321 (the misguided fix-attempt that this supersedes).
Supersedes PR #2321's two-jobs-sharing-a-name approach, which didn't
actually clear branch-protection's required-check evaluation. Live
test on PR #2314: GraphQL `isRequired` confirmed BOTH check runs
under "Canvas (Next.js)" name (one SUCCESS via no-op, one SKIPPED via
real job) registered, and the SKIPPED one kept mergeStateStatus =
BLOCKED despite the SUCCESS sibling. Branch protection's "set of
matching contexts" semantic is stricter than the durable feedback
memory documented — at least one passing isn't enough; SKIPPED
counts as not-passed regardless.
Real fix: ONE job that always runs (no job-level `if:`), with all
real work gated on the path filter via per-step `if:`. Produces
exactly one "Canvas (Next.js)" check run per commit, always SUCCEEDS,
regardless of which paths changed. Costs ~10s of always-on CI runtime
per PR — negligible vs. the manual-merge cost when the BLOCKED state
catches us.
This same anti-pattern probably affects Platform (Go) (`platform`
filter), Python Lint & Test (`python` filter), and Shellcheck (E2E
scripts) (`scripts` filter) — all required, all path-gated. PR-A and
PR-2321 merged because they happened to trigger every filter; PR-B
only missed canvas. File a follow-up issue to apply the same
single-job-conditional-steps pattern across those required jobs to
remove the latent merge-blocker.
Updates feedback memory: branch_protection_check_name_parity is wrong
about "two jobs sharing name + at-least-one-success works." Need to
correct the note.
PRs that don't touch canvas/** paths skip the Canvas (Next.js) job via
its `if: needs.changes.outputs.canvas == 'true'` guard. GitHub reports
SKIPPED for that conclusion. Branch protection on staging requires
Canvas (Next.js) — and treats SKIPPED as not-passed, blocking merge
on every workspace-server-only or migration-only PR.
This is the design pattern documented in feedback memory
"branch_protection_check_name_parity": split into a real job + a
no-op shadow that share the same `name:`. Exactly one runs per PR;
both report the same check context, and at least one always reports
SUCCESS, satisfying the required check.
The no-op job runs in a few seconds (single `echo` step) and produces
the right check context for any PR that has changes outside canvas/**.
Concrete blocker that prompted this: PR #2314 (RFC #2312 PR-B) sat
APPROVED + CI-green + UP-TO-DATE for half an hour with mergeStateStatus
BLOCKED, traced via the GraphQL `isRequired` field to a single
SKIPPED Canvas (Next.js) check. PRs #2319 (PR-F) and the rest of the
RFC #2312 stack would have hit the same wall.
Step 2 of #1815. Step 1 (instrumentation in canvas/vitest.config.ts)
already shipped — the inline comment there explicitly defers wiring
into CI to a follow-up because turning on a 70% threshold blind would
either fail CI immediately or paper over a real gap with an ad-hoc
exclude list.
This PR ships the observability half:
- Replaces `npx vitest run` with `npx vitest run --coverage` in the
canvas-build job. Coverage gets reported on every PR; no threshold
gate yet (vitest.config.ts intentionally doesn't set thresholds).
- Adds an artifact upload step for canvas/coverage/ (HTML + json-summary)
so reviewers can browse the coverage report from any PR. 7-day
retention; if-no-files-found=warn so a step skip doesn't fail.
Step 3 (thresholds + hard gate) is the natural follow-up — track in a
new sub-issue once we've seen ~5-10 PRs of baseline data and know
where current coverage sits. The issue body proposed lines:70 /
functions:70 / branches:65 / statements:70; that may need adjustment
once the baseline lands.
Closes the Step-2 portion of #1815. Step 3 stays open or gets a fresh
issue depending on your preference.

Add a comment block at the top of auto-promote-staging.yml naming the
load-bearing one-time repo setting that the workflow depends on:
Settings → Actions → General → Workflow permissions
→ ✅ Allow GitHub Actions to create and approve pull requests
Without this toggle, every workflow_run fails with
"GitHub Actions is not permitted to create or approve pull requests
(createPullRequest)". Observed 2026-04-29 01:43 UTC blocking the
fcd87b9 promotion (PRs #2248 + #2249); manually bridged via PR #2252.
The setting is invisible to anyone reading the workflow file, but the
workflow cannot do its job without it. Documenting here so the next
time it gets toggled off (org admin change, repo migration, audit
cleanup) the failure mode points at the cause rather than another
round of "why is auto-promote broken."

Mirror the sweep-cf-orphans hardening (#2248) on publish-runtime's
TEMPLATE_DISPATCH_TOKEN gate. The previous behaviour was to print
:⚠️:skipping cascade — templates will pick up the new version
on their own next rebuild and exit 0. That message is wrong: the 8
workspace-template repos only rebuild on this repository_dispatch
fanout. Without the dispatch they stay pinned to whatever runtime
version they last saw, and the gap is invisible until someone
notices a template several versions behind weeks later.
Behaviour after this PR:
- push (auto-trigger on workspace/runtime/** changes) → exit 1
- workflow_dispatch (manual operator) → exit 0
with a warning (operator already accepted state; let them rerun
after restoring the secret)
The token-missing path now also names the consequence concretely
("templates will NOT pick up the new version until this token is
restored") so future operators see the actionable line, not the
misleading "they'll catch up on their own" message.

Replace the soft-skip-with-warning behaviour for scheduled runs of the
hourly Cloudflare orphan sweeper with an explicit failure when the six
required secrets aren't set. Manual workflow_dispatch keeps the
soft-skip path so an operator can short-circuit a deliberate rerun
without redoing the secrets dance — they accepted the state when they
clicked the button.
Why: from some-date to 2026-04-28, all six secrets were unset on the
repo. Every hourly tick printed a yellow :⚠️: and exited 0,
which GitHub registers as "completed/success" — the sweeper was
indistinguishable from a healthy janitor with nothing to do. Cloudflare
orphans accumulated unobserved to 152/200 (~76% of the zone quota),
and only surfaced via a manual audit. The mechanism to catch this kind
of regression is to make the workflow loud: red runs prompt
investigation, green runs are presumed healthy.
Schedule/workflow_run/push paths now print three ::error:: lines
naming the missing secrets, the fix, and a one-line reference to this
incident, then exit 1.

Mirrors the fix#2234 applied to auto-sync-main-to-staging.yml in the
reverse direction. Both workflows now use the same merge-queue path
that humans use; no special-case bypass.
Why
Every tick of auto-promote-staging.yml since main's branch protection
went stricter has been failing with:
remote: error: GH006: Protected branch update failed for refs/heads/main.
remote: - Required status checks "Analyze (go)", "Analyze (javascript-typescript)",
"Analyze (python)", "Canvas (Next.js)", "Detect changes",
"E2E API Smoke Test", "Platform (Go)", "Python Lint & Test",
and "Shellcheck (E2E scripts)" were not set by the expected
GitHub apps.
remote: - Changes must be made through a pull request.
The previous version did `git merge --ff-only origin/staging &&
git push origin main` directly. That works against a permissive
branch — it doesn't work against a ruleset that requires checks
satisfied by the expected GitHub apps. Only PR merges through the
queue produce check runs from the right apps.
Result was that today's 12+ merges to staging never propagated to
main; the auto-promote ran every tick and failed every tick, while
operators had to keep opening manual `staging → main` bridges.
Fix
- Replace the direct git push step with a step that opens (or reuses)
a PR base=main head=staging and enables auto-merge. The merge queue
lands it once gates are green on the merge_group ref.
- The PR's head IS the staging branch (no per-SHA promote branch
needed) — the whole purpose is "advance main to staging's tip".
- Add `pull-requests: write` permission so the workflow can call
gh pr create + gh pr merge --auto.
- Drop the `git merge-base --is-ancestor` divergence check — the
merge queue itself enforces branch protection now, and rejects
the PR if main has diverged from staging history.
Loop safety preserved: when this PR's merge lands on main, it
triggers auto-sync-main-to-staging.yml which opens a sync PR back
to staging. That sync PR's eventual merge is by GITHUB_TOKEN (the
merge queue) which doesn't trigger downstream workflow_run events
— so auto-promote-staging.yml does NOT re-fire from its own merge
landing.

Consolidates the remaining safe-to-merge dependabot PRs from the
2026-04-28 wave into one consumable PR. Replaces three earlier
single-bump PRs (#2245, #2230, #2231) which were closed in favor of
this single batch — same pattern as #2235.
GitHub Actions majors (SHA-pinned per org convention):
github/codeql-action v3 → v4.35.2 (#2228)
actions/setup-node v4 → v6.4.0 (#2218)
actions/upload-artifact v4 → v7.0.1 (#2216)
actions/setup-python v5 → v6.2.0 (#2214)
npm dev deps (canvas/, lockfile regenerated in node:22-bookworm
container so @emnapi/* and other Linux-only optional deps are
properly resolved — Mac-native `npm install` strips them, which
caused the earlier #2235 batch to drop these two):
@types/node ^22 → ^25.6 (#2231)
jsdom ^25 → ^29.1 (#2230)
Why each is safe
setup-node v4 → v6 / setup-python v5 → v6:
Every consumer call pins node-version / python-version
explicitly. v5 / v6 changed defaults but pinned consumers
are unaffected. Confirmed via grep across .github/workflows/
— all setup-node call sites pin '20' or '22', all
setup-python call sites pin '3.11'.
codeql-action v3 → v4.35.2:
Used as init/autobuild/analyze sub-actions in codeql.yml.
v4 bundles a newer CodeQL CLI; ubuntu-latest auto-updates
so functional behavior is unchanged. The deprecated
CODEQL_ACTION_CLEANUP_TRAP_CACHES env var (per v4.35.2
release notes) is undocumented and we don't set it.
upload-artifact v4 → v7.0.1:
v6 introduced Node.js 24 runtime requiring Actions Runner
>= 2.327.1. All upload-artifact users (codeql.yml,
e2e-staging-canvas.yml) run on `ubuntu-latest` (GitHub-
hosted), which auto-updates the runner agent. Self-hosted
runners are NOT used for these jobs.
@types/node 22 → 25 / jsdom 25 → 29:
Both are dev-only — @types/node is type definitions,
jsdom backs vitest's DOM environment. Tests pass:
79 files / 1154 tests in node:22-bookworm container.
Verified locally (Linux container so the lockfile reflects what
CI's `npm ci` will install):
- cd canvas && npm install --include=optional → 169 packages
- npm test → 1154/1154 pass
- npm ci → clean install succeeds
- npm run build → Next.js prerendering succeeds
Closes when this lands (the 3 individual auto-merge PRs from earlier
were closed):
#2228#2218#2216#2214#2231#2230
NOT included (CI failing on dependabot's own run — major framework
bumps that need code-side migration tasks, not safe auto-bumps):
#2233 next 15 → 16
#2232 tailwindcss 3 → 4
#2226 typescript 5 → 6
