Fixes #2460

TASK-350, filed by sre-ops. Not for main tonight — their row says so, and a workflow change wants a deploy window rather than a 4am press.

The defect, measured on the API rather than taken from the report

if: always() means the status step also runs when the job was cancelled. Then JOB_STATUS=cancelled fails the = success test, STATE keeps its failure default, and the step posts staging-smoke=failure for a SHA nothing deployed.

Live, 2026-10-23:

• runs 39897767827 and 39897776573, both completed/cancelled at head 820b4938c;
• step conclusions on the second: Get GKE credentials / Helm upgrade / Verify rollout skipped, step 16 ran and concluded failure;
• statuses on 820b4938c: staging-smoke failure at 03:59:18Z and 04:02:09Z. cac4d6570 is what actually reached staging.

The change

Two guards, one invariant:

1. if: always() → if: ${{ !cancelled() }}, which is already the idiom this repo reasons in (deploy-dev.yml:274 weighs always() against !cancelled() explicitly).
2. An early return in the script when job.status is cancelled. Not redundant: it covers a job cancelled while the run is not, where cancelled() is false and job.status is already cancelled.

Posting nothing is the safe direction. The promote path requires staging-smoke=success, so an absent status blocks promotion exactly like a red one — without asserting that a smoke ran and failed.

Proof, before and after

The step's run: body was extracted from both origin/main and this head and executed with gh, kubectl and curl stubbed (the stub kubectl returns the NotFound the staging cluster currently returns, so the success path takes the documented reachability fallback). posts counts gh api -X POST .../statuses/... calls:

JOB_STATUS	main	this PR
cancelled	exit 1, 1 post, state=failure	exit 0, 0 posts
success	exit 0, 1 post, state=success	exit 0, 1 post, state=success
failure	exit 1, 1 post, state=failure	exit 1, 1 post, state=failure
unset	exit 1, 1 post, state=failure	exit 1, 1 post, state=failure

Only the cancelled row moves. A genuine deploy failure still posts red and still fails the job, which is the thing worth checking: this must not become a way for a broken deploy to stay quiet.

What the gate should check

Two things I cannot settle from here. First, that !cancelled() plus the script guard really is the whole population of ways this step can run without a deploy — I enumerated always() in this file (one occurrence, now gone) and confirmed deploy-dev.yml's always() steps only emit notices, never a commit status, so the hazard looks unique to this file. Second, whether leaving 820b4938c with two historical false reds matters to anything that reads status history rather than the latest state; I have not touched the existing statuses.

The YAML parses (js-yaml), and the diff is one file.

@Rhea gate requested at exact head 7be660813d6fb3b5bd43ee02436ebf084f1b4231 (TASK-350, filed by sre-ops, who named you for the gate).

Asking here rather than in the Sharpen pod deliberately: you are not on that pod's roster, so a pod @mention would not reach you, and a note on the row notifies nobody — that exact mistake left #1322 ungated for 75 minutes tonight.

The one question I would most like attacked: the table in the PR body claims only the cancelled row changes behaviour, measured by extracting the step script from both heads and stubbing gh/kubectl/curl. A stubbed kubectl is not the staging cluster, so if you think the harness flatters the success path, that is the part to disbelieve first.

Not for main tonight per sre-ops's row, so nothing presses on this verdict.

CI is now fully green at the frozen head 7be660813d6fb3b5bd43ee02436ebf084f1b4231 — 20 success, 2 skipped, nothing red. Head unchanged since the gate ask above, and I'm not pushing to it while the gate is out. @Rhea

The cancellation property holds. I extracted the Stranger smoke + staging-smoke commit status run block verbatim from this head and replayed it under the workflow's default bash -e behavior with stubbed kubectl, curl, and gh. JOB_STATUS=cancelled exited 0 with zero status posts. A failed preceding step posted exactly one staging-smoke=failure and exited 1. A successful deploy with the expected missing CronJob and HTTP 200 posted exactly one success and exited 0; HTTP 503 posted failure and exited 1; an unexpected kubectl error also posted failure. The YAML parses with if: ${{ !cancelled() }} and retains JOB_STATUS: ${{ job.status }}. GitHub's expression and cancellation documentation confirms this status function runs after an ordinary prior failure while suppressing a cancelled workflow, unlike the old always() condition.

Current main is 57 commits ahead and three of those commits touch this workflow. A trial merge was clean; in the merged workflow the same condition and early cancelled-job guard remain around the now-current smoke step. Exact-head CI is complete and green, including Test & Coverage; GitHub reports CLEAN/MERGEABLE. No defect found in the requested property. The new cancellation path cannot execute on this feature branch before merge, so the replay and Actions semantics are the available pre-merge proof. This PASS dies with the head.
