Deployment & Promotion

Deploy is decoupled from release. Promotion is manual and deliberate — nothing self-syncs to Prod.

What gets promoted

Every one of these changes must be applied to both Supabase projects (Dev first, then Prod):

• Migrations · Edge Functions · secrets · storage buckets · cron schedules.

Full procedure + parity-verification SQL + CLI connectivity gotchas: supabase/docs/PROMOTION_RUNBOOK.md.

Frontend deploy

• DEV: auto on green CI from develop → Cloudflare Pages DEV.
• UAT / PROD: manual workflow_dispatch from uat / main (after verify-ci).
• Each build injects its own VITE_SUPABASE_*.

Design sync — a required step of develop → uat (ADR-0015)

Promotion to UAT is where accumulated design drift is reconciled. It is attached to this gate deliberately: a "periodic" audit has no owner and no forcing function, whereas this promotion is manual and already happens.

1. Open the design drift ledger.
2. For every 🔴 open row: push the change into the Claude Design MCP project (via DesignSync) and mark it 🟢 synced — or mark it 🟡 deferred with a written reason on the row.
3. A row is never silently dropped. correction and none rows need no action (⚪).

Skipping this does not break the deploy — it breaks the next screen designed from the design project, which will be drawn against stale foundations. That failure has already occurred once here (the quarantined QR setu prototype-handoff/), so treat it as a real step, not paperwork.

Edge Function deploy

npm run functions:deploy -- --project-ref <ref> [--only fn-a,fn-b] [--dry-run]

• Explicit --project-ref always required (never relies on supabase link state).
• Skips _shared/utils (no index.ts).
• Deploy to Dev, verify, then Prod.

Rollback (DR runbooks now; PITR deferred)

Surface	Rollback
Frontend	Cloudflare Pages instant rollback to a previous deployment.
Backend (schema)	Compensating expand-contract migration (not an in-place revert).
Edge Function	git revert + redeploy.
Data safety net	Supabase managed daily backups (interim). PITR + RPO/RTO + restore drills = deferred decision.

Feature flags / kill-switches

Decouple deploy from release: land code dark behind a flag, flip it on when ready, flip it off to mitigate. (Target capability per CLAUDE.md.)

Post-deploy verification

• Verify end-to-end in-app, not just via tests — part of the Definition of Done.
• Deploy-smoke runs against the real URL (mind Cloudflare Bot Fight Mode 403s).
