Workflow Ship And Observe

workflow-ship-and-observe — Release, Verify, Observe, Roll Back

Degree of freedom: MIXED. Rollback-vs-hotfix [HIGH freedom]; pin target/SHA, prove revision, observe window [LOW freedom — run exactly].

Shipping is not merging. A release is done only when the intended revision is live on the confirmed target, production smoke checks pass, and a defined monitoring window elapses without crossing rollback thresholds — or a rollback/hotfix has been executed.

Prove the deployed revision, then watch it. A 200 from a URL is not proof that your code is live, and "it deployed" is not proof that it is healthy.

How to reason

1. Pin — SHA, environment, mechanism, rollback, signals
2. Ship — pipeline deploy; backend deps first
3. Prove — live revision equals SHA; smoke on critical flows
4. Watch — window elapsed under thresholds, or roll back

Worked example

Pin: a1b2c3d on Vercel production; rollback = previous promotion; Sentry + 5xx threshold set. Ship: migrations applied; vercel deploy --prod succeeded. Prove: /version returns a1b2c3d; checkout + login smoke 2xx. Watch: 2h window, error rate flat → STABLE. A 5xx spike would have promoted previous and re-smoked.

Self-critique before reporting

• Revision proven — a 200 is not "our SHA is live"
• Level honest — deployed-verified ≠ observed-stable
• Threshold acted — known-bad prod was not "monitored more"
• Right owner — smoke methodology only → deploy-verify; npm package → deploy-npm; not-yet-green → workflow-green-repo

Phase 0 — Pin the target and the revision [LOW freedom — run exactly]

Never guess where or what you are shipping. Establish:

1. Source revision — the exact commit SHA to release. Confirm it is merged and that the repository is green (route to workflow-green-repo / complete-everything if not). Record the SHA.
2. Target environment — which environment and provider. Discover from the repo, do not assume: vercel.json, netlify.toml, fly.toml, Dockerfile, render.yaml, Kubernetes manifests, GitHub Actions deploy workflows, app.json/EAS, supabase/config.toml, Terraform. Confirm the environment (staging vs production) with the user once and reuse it.
3. Deploy mechanism — CI-on-merge, a manual pipeline trigger, or a CLI command. Identify the exact command/workflow and how to read its status.
4. Backend dependencies — migrations, edge functions, RLS, buckets, secrets, cron. Per full-stack-ship-discipline, these must deploy and be verified alongside the frontend. Non-destructive schema required by the approved release ships without re-asking on a confirmed target; destructive data operations always ask first.
5. Rollback plan — the concrete, executable way to revert this target (previous deployment promotion, image/tag rollback, revert-and-redeploy, migration down-path). If no rollback exists, say so before shipping.
6. Signals — where errors and latency are observed (Sentry, provider logs, Supabase logs/advisors, uptime checks) and the thresholds that mean "roll back."

Write .cursor/ship-state.md:

# Ship & Observe: <app> → <environment>
Revision: <sha>
Target/provider: <name>
Deploy: <command/workflow>
Rollback: <exact procedure>
Monitor window: <duration> · thresholds: <error rate / latency / crash-free>

## Steps
- [ ] preflight: repo green + revision confirmed
- [ ] backend deps deployed + verified
- [ ] deploy triggered
- [ ] deployed revision matches <sha>
- [ ] production smoke: <critical flows>
- [ ] monitoring window elapsed within thresholds
- [ ] stable OR rollback/hotfix executed

## Evidence
- <step>: <command/result>

Phase 1 — Preflight [LOW freedom — run exactly]

• Confirm the release SHA is merged and green. Do not ship red or unmerged code.
• Deploy and verify backend dependencies first, so the frontend does not hit a missing table/function on first request. Verify objects exist as the role the client uses.
• Confirm the rollback procedure is real and, where possible, dry-run it.

Phase 2 — Deploy [LOW freedom — run exactly]

• Trigger the deploy via the identified mechanism. Never hand-edit production state outside the pipeline.
• Wait for the deploy to reach a terminal state; capture the build/deploy logs. A failed or partial deploy is a stop-and-fix, not a proceed.

Phase 3 — Verify the revision is live [LOW freedom — run exactly]

• Confirm the deployed revision equals the intended SHA — via the provider's deployment metadata, a /version/build-id endpoint, a build stamp, or asset hashes. A reachable URL alone is not proof.
• Run production smoke checks on the critical flows: real navigation, auth, a primary read and a primary write path. Capture console, network (2xx where expected), and screenshots as evidence. Keep artifacts under .playwright-mcp/.

Phase 4 — Observe the stability window [LOW freedom — run exactly]

• Watch the defined signals for the agreed window (scale it to release risk).
• Track error rate/new issues (Sentry), latency and 5xx (provider/Supabase logs), new ERROR advisors, and crash-free rate for mobile.
• Crossing a threshold triggers Phase 5. Not crossing it after the window elapses is the only path to a "stable" claim.

Phase 5 — Roll back or hotfix (only if a threshold is crossed) [HIGH freedom]

• If signals breach thresholds: execute the rollback procedure immediately, confirm the prior healthy revision is live, and re-verify smoke checks.
• If forward-fix is clearly faster and safer than rollback, ship a hotfix through the same pipeline and re-enter Phase 3. Record the decision and why.
• Never leave production in a known-bad state to "monitor more."

Phase 6 — Report [LOW freedom — do not skip]

## Ship & Observe — report
Released: <sha> → <environment/provider>
### Result: STABLE | ROLLED BACK | HOTFIXED | BLOCKED
### Evidence
- deploy: <log/status>
- revision live: <how confirmed> = <sha>
- smoke: <flows> → <result + artifacts>
- monitoring: <window> → error rate <x>, latency <y>, crash-free <z>
### Rollback/hotfix (if any)
- trigger: <threshold crossed> → action: <what ran> → outcome
### Follow-ups
- none | <tracked item>

Completion level is deployed-verified after Phase 3 and observed-stable only after Phase 4 passes. Do not claim stability from a single smoke test.
