# 08 — Deploy and Runtime Verification

Enforce the mandatory typecheck→deploy→CDN-purge→prod-E2E→visual-verify loop after every code change; never mark done without a live PROD assertion.

## Mandatory deploy loop (every code change)

1. Build + typecheck
2. `wrangler deploy` (or platform equivalent)
3. Purge CDN (`wrangler cache purge` or `curl -X POST https://api.cloudflare.com/client/v4/zones/{id}/purge_cache`)
4. Fetch each changed route on PROD URL via curl + Playwright
5. Assert new content / headers / JSON-LD / status live
6. AI vision QA at 6 viewports (per `_kernel/standards.md#breakpoints`)
7. Fix-forward (max 3 redeploys) — never silently fail
8. Only then mark DONE

"Local typecheck + build pass" is NOT done. Per `rules/verification-loop.md`.

## Auth fallback chain

- `CLOUDFLARE_API_TOKEN` from `/Users/Apple/.local/bin/get-secret`
- On 401: `CLOUDFLARE_API_KEY` + `CLOUDFLARE_EMAIL`
- Both stale: prompt `! npx wrangler login`, resume deploy once fresh
- NEVER silently skip deploy because creds missing — surface as blocker

## Cloudflare `cf` CLI transition (beta — doctrine stays wrangler-first)

- `cf` CLI open beta since 2026-09-28: ~3,000 generated API commands (vs wrangler's ~280). Wrangler gets ONE final major redirecting to cf, then 18-month maintenance; config format moves `wrangler.jsonc` → `cloudflare.config.ts` with typed bindings. Wrangler now requires Node ≥22.
- Keep every deploy command wrangler-based while cf is beta; re-evaluate at cf GA.

## Workers Builds (native CI/CD)

- Configure in `wrangler.jsonc` `build` block
- Auto-deploys on push to `main` per `rules/main-only-branch.md`
- Runs `npm install` + `npm run build` + `wrangler deploy`
- Secrets injected via dashboard or `wrangler secret put` per `rules/secret-provisioning.md`

## Secrets management

- `wrangler secret put KEY` — runtime secrets; `wrangler secret list` — names only, never values
- Two-way mirror: every prod secret also in chezmoi (`~/.local/share/chezmoi/home/.chezmoitemplates/secrets/{KEY}`)
- `scripts/check-secrets.mjs --audit` runs before every deploy
- Per `rules/secret-provisioning.md` + `rules/secret-auto-provisioning.md`

## D1 backup strategy

- **Time Travel** — 30-day PIT, free: `wrangler d1 time-travel restore <db> --timestamp=<ts>`
- **D1 → R2 long-term** — `wrangler d1 export <db> --output=backup.sql` + upload to R2 daily via cron
- **Pre-migration safety** — `wrangler d1 export` BEFORE any destructive migration
- 1 TB storage limit per account, 10 GB per database

## Rollback procedures

- **Worker** — `wrangler rollback <version-id>` in <30s
- **D1** — Time Travel PIT to known-good timestamp
- **R2** — bucket versioning enabled; revert via object version
- **Combined deploy** — log `{commit, version_id, timestamp}` to D1 after every deploy; rollback target one query away

## Auto-rollback gates (gradual deployment)

- 1% → watch error rate 5 min → 10% → watch 5 min → 100%
- Auto-rollback at p99 error >1% or LCP regression >20%

## Browser console gate

Per `rules/verification-loop.md` § Console-error gate — all must be 0:

- Console errors / CSP report-uri violations / Trusted Types violations / Deprecation warnings / Third-party script errors

Run as part of `npm run e2e:prod` Playwright suite.

## Cross-browser smoke

Per `_kernel/standards.md#breakpoints` × 3 browsers (Chromium, Firefox, WebKit):

- Homepage loads; primary CTA clickable; form submit succeeds (Turnstile invisible)
- No console errors at any breakpoint
- Lighthouse Perf ≥75 + A11y ≥95

## Observability check post-deploy

Verify each is firing (missing = blocker):

- Sentry — recent events in dashboard
- PostHog — recent pageviews + captures
- Workers Tracing — recent traces in Axiom (Tier 2)
- AI Gateway — recent LLM calls logged (Tier 3)
- GA4 — recent events (Tier 2)

## GitHub auto-configuration

- New project: `gh repo create` with template
- Add CF Workers Builds via dashboard or API
- Wire OIDC + `cloudflare/wrangler-action@v3` for CI
- Trust policy: GitHub OIDC token verifies repo + branch — no long-lived `CLOUDFLARE_API_TOKEN` in repo secrets

## Per-deploy CHANGELOG entry

Every deploy logs to `CHANGELOG.md` (`## [version] — YYYY-MM-DD` / `### Added / Changed / Fixed`). Auto-generated by `changelog-generator` agent from conventional commits.
