5. ~~**Hosting & deployment**~~ — ✅ Complete. Alpine Docker image (131 MB), Fly.io config, release overlays, health check endpoint, hardcoded path fixes for releases. Observability: LiveDashboard in prod behind admin auth, ErrorTracker for exception capture, JSON structured logging, Oban/LiveView telemetry metrics, os_mon for CPU/disk/memory. 5. ~~**Hosting & deployment**~~ — ✅ Complete.

6. **Litestream / SQLite replication** — Litestream for continuous SQLite backup to S3-compatible storage. Point-in-time recovery. Simple sidecar process, no code changes needed, works with vanilla SQLite. For the hosted platform (Tier 5), evaluate [Turso](https://turso.tech/) (libSQL fork of SQLite) with embedded read replicas via [ecto_libsql](https://github.com/ocean/ecto_libsql) adapter — gives multi-node reads without a separate replication daemon, but adds a dependency on the libSQL fork. 6. **Litestream / SQLite replication** — Litestream for continuous SQLite backup to S3-compatible storage.

7. ~~**CI pipeline**~~ — ✅ Complete. `mix ci` alias: compile --warning-as-errors, deps.unlock --unused, format --check-formatted, credo, dialyzer, test. Credo configured with sensible defaults. Dialyzer with ignore file for false positives (Stripe types, Mix tasks, ExUnit internals). 612 tests, 0 failures. 7. ~~**CI pipeline**~~ — ✅ Complete. `mix ci` alias: compile --warning-as-errors, deps.unlock --unused, format --check-formatted, credo, dialyzer, test.

8. **PageSpeed in CI** — Lighthouse CI to catch regressions. Fail the build if score drops below threshold. Protects the current 100% score. 8. ~~**PageSpeed in CI**~~ — ✅ Complete. `mix lighthouse` task runs Google Lighthouse against the shop with configurable thresholds. Builds production assets (minified + digested + gzipped), waits for image variant cache, checks all 4 categories. Mobile: 99-100, Desktop: 97-100 across all pages. Unconditional gzip on Plug.Static.
9. **End-to-end tests** — Wallaby or similar for browser-based tests of critical flows: browse → add to cart → checkout → order confirmation. Covers the full happy path plus key error cases. 9. **End-to-end tests** — Wallaby or similar for browser-based tests of critical flows: browse → add to cart → checkout → order confirmation.
