Two related workflow hygiene changes:
## (1) canary-verify: graceful-skip when canary secrets absent
Before: canary-verify hit `scripts/canary-smoke.sh` which exited
non-zero when CANARY_TENANT_URLS was empty. Every main publish
ran → canary-verify failed → red check on main CI signal (7/7 in
past 24h). Noise, no value.
After: smoke step detects the missing-secrets case, writes a
warning to the step summary, sets an output `smoke_ran=false`,
and exits 0. The workflow completes green without pretending to
have tested anything.
Gated downstream: `promote-to-latest` now requires BOTH
`needs.canary-smoke.result == success` AND
`needs.canary-smoke.outputs.smoke_ran == true`. A skip does NOT
auto-promote — manual `promote-latest.yml` remains the release
gate while Phase 2 canary is absent (see
molecule-controlplane/docs/canary-tenants.md for the fleet
stand-up plan + decision framework).
When the canary fleet is stood up and secrets populated: delete
the early-exit branch + the smoke_ran gate. The workflow goes back
to its original "smoke gates promotion" semantics.
## (2) auto-promote-staging.yml — draft
New workflow that fires after CI / E2E Staging Canvas / E2E API /
CodeQL complete on the staging branch, checks that ALL four are
green on the same SHA, and fast-forwards `main` to that SHA.
Shipped disabled: the promote step is gated behind repo variable
`AUTO_PROMOTE_ENABLED=true`. Until that's set, the workflow
dry-runs and logs what it would have done. Toggle via Settings →
Variables when staging CI has been reliably green for a few days.
Safety:
- workflow_run events only fire on push to staging (PRs into
staging don't promote).
- Every required gate must be `completed/success` on the same
head_sha. Pending / failed / skipped / cancelled → abort.
- `--ff-only` push. Refuses to advance main if it has diverged
from staging history (someone landed a direct-to-main commit
that's not on staging). Human resolves the fork.
- `workflow_dispatch` with `force=true` lets us test the flow
end-to-end before flipping the variable on.
Motivation: molecule-core#1496 has been open with 1172 commits
divergence between staging and main. Today that trapped PR #1526
(dynamic canvas runtime dropdown) on staging while prod users
hit the hardcoded-dropdown bug. Auto-promote retires the bulk
staging→main PR pattern once the staging CI it depends on is
reliable.

molecule-core is a public repo — GHA-hosted minutes are free. The
self-hosted Mac mini was only in play to dodge GHA rate limits
(memory feedback_selfhosted_runner), but for these specific
workflows it came with real costs:
- Docker-push workflows emulated linux/amd64 from arm64 via QEMU —
every canvas + platform image build ran ~2-3x slower than native.
- Six PRs worth of keychain-avoidance hacks in publish-* because
`docker login` on macOS writes to osxkeychain unconditionally,
and the Mac mini's launchd user-agent keychain is locked.
- Homebrew pin-down environment variables (HOMEBREW_NO_*) sprinkled
everywhere to work around the shared /opt/homebrew symlink mess
on the runner.
- Setup-python@v5 couldn't write to /Users/runner, so ci.yml
python-lint resorted to a hand-rolled Homebrew python3.11 dance.
- Single runner → fan-out contention; CodeQL's 45-min analysis
fought the canvas publish for the one slot.
Changes across the 7 workflows:
- runs-on: [self-hosted, macos, arm64] → ubuntu-latest (every job)
- publish-canvas-image + publish-workspace-server-image:
drop the hand-rolled auths-map step + QEMU setup + buildx v4
→ docker/login-action@v3 + setup-buildx@v3. Linux + amd64
target = native build.
- canary-verify + promote-latest: replace `brew install crane` +
HOMEBREW_NO_* incantations with imjasonh/setup-crane@v0.4.
- codeql.yml: drop `brew install jq` — jq is preinstalled on
ubuntu-latest.
- ci.yml shellcheck: drop the self-hosted existence check —
shellcheck is preinstalled via apt.
- ci.yml python-lint: replace the Homebrew python3.11 path dance
with actions/setup-python@v5 (which works fine on GHA-hosted),
add requirements.txt caching while we're there.
- Remove stale comments referencing "the self-hosted runner",
"Mac mini", keychain, osxkeychain etc.
The self-hosted Mac mini remains in service for private-repo
workflows only. Memory feedback_selfhosted_runner updated to
reflect the public-repo scope carve-out.
Net -96 lines across the 7 files.

The canary-verify workflow blocked the self-hosted runner for a fixed
6 minutes regardless of whether canaries had already updated. This
wastes the runner slot when canaries update in 2-3 minutes.
Fix: poll each canary's /health endpoint every 30s for up to 7 min.
Exit early when all canaries report the expected SHA. Falls back to
proceeding after timeout — the smoke suite validates regardless.
Typical time saving: ~3-4 minutes per canary verify run.

GitHub-hosted ubuntu-latest runs on this repo hit "recent account
payments have failed or your spending limit needs to be increased"
— same root cause as the publish + CodeQL + molecule-app workflow
moves earlier this quarter. canary-verify was the last one still on
ubuntu-latest.
Switches both jobs to [self-hosted, macos, arm64]. crane install
switched from Linux tarball to brew (matches promote-latest.yml's
install pattern + avoids /usr/local/bin write perms on the shared
mac mini).

Completes the canary release train. Before this, publish-workspace-
server-image.yml pushed both :staging-<sha> and :latest on every
main merge — meaning the prod tenant fleet auto-pulled every image
immediately, before any post-deploy smoke test. A broken image
(think: this morning's E2E current_task drift, but shipped at 3am
instead of caught in CI) would have fanned out to every running
tenant within 5 min.
Now:
- publish workflow pushes :staging-<sha> ONLY
- canary tenants are configured to track :staging-<sha>; they pick
up the new image on their next auto-update cycle
- canary-verify.yml runs the smoke suite (Phase 2) after the sleep
- on green: a new promote-to-latest job uses crane to remotely
retag :staging-<sha> → :latest for both platform and tenant images
- prod tenants auto-update to the newly-retagged :latest within
their usual 5-min window
- on red: :latest stays frozen on prior good digest; prod is untouched
crane is pulled onto the runner (~4 MB, GitHub release) rather than
docker-daemon retag so the workflow doesn't need a privileged runner.
Rollback: if canary passed but something surfaces post-promotion,
operator runs "crane tag ghcr.io/molecule-ai/platform:<prior-good-sha>
latest" manually. A follow-up can wrap that in a Phase 4 admin
endpoint / script.

Post-deploy verification for staging tenant images. Runs against the
canary fleet after each publish-workspace-server-image build — catches
auto-update breakage (a la today's E2E current_task drift) before it
propagates to the prod tenant fleet that auto-pulls :latest every 5 min.
scripts/canary-smoke.sh iterates a space-sep list of canary base URLs
(paired with their ADMIN_TOKENs) and checks:
- /admin/liveness reachable with admin bearer (tenant boot OK)
- /workspaces list responds (wsAuth + DB path OK)
- /memories/commit + /memories/search round-trip (encryption + scrubber)
- /events admin read (AdminAuth C4 path)
- /admin/liveness without bearer returns 401 (C4 fail-closed regression)
.github/workflows/canary-verify.yml runs after publish succeeds:
- 6-min sleep (tenant auto-updater pulls every 5 min)
- bash scripts/canary-smoke.sh with secrets pulled from repo settings
- on failure: writes a Step Summary flagging that :latest should be
rolled back to prior known-good digest
Phase 3 follow-up will split the publish workflow so only
:staging-<sha> ships initially, and canary-verify's green gate is
what promotes :staging-<sha> → :latest. This commit lays the test
gate alone so we have something running against tenants immediately.
Secrets to set in GitHub repo settings before this workflow can run:
- CANARY_TENANT_URLS (space-sep list)
- CANARY_ADMIN_TOKENS (same order as URLs)
- CANARY_CP_SHARED_SECRET (matches staging CP PROVISION_SHARED_SECRET)
