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.
