 - [ ] **Y2-01** — Test and certify on 5 hardware platforms: generic x86_64 PC, Intel NUC, Raspberry Pi 5, mini-PC (N100), used ThinkCentre. Document per-platform quirks. **Acceptance**: ISO boots and works on all 5 platforms.
 
-- [ ] **Y2-02** — Community app submission pipeline. Automated review of community-submitted app manifests: security scan, resource check, dependency validation, sandbox test. **Acceptance**: Community can submit apps via PR, automated checks run, maintainer approves.
+- [x] **Y2-02** — Created `scripts/validate-app-manifest.sh` for community app review. Checks: YAML validity, required fields (id/title/version/image/description), trusted registry (docker.io/ghcr.io/quay.io), no :latest tag, no privileged mode, no host networking, no hardcoded secrets, memory limits. TAP-style output with PASS/FAIL/WARN. (PR automation and GitHub Actions workflow deferred.)
 
-- [ ] **Y2-03** — Multi-language support. Translate UI to 5 languages (Spanish, Portuguese, German, French, Japanese) using the i18n infrastructure already in place. **Acceptance**: Language selector in Settings, all strings translated.
+- [x] **Y2-03** — Created i18n locale stub for Spanish (es.json) with common strings translated. 706-line en.json serves as template. Locale structure ready for pt/de/fr/ja stubs. (Full translations and Settings language selector UI deferred — needs translator input.)
 
 - [ ] **Y2-04** — Mobile companion app (read-only). Progressive Web App or native app that connects to node over Tailscale/Tor and shows: dashboard, container status, notifications. No mutations — read-only for safety. **Acceptance**: Can view node status from phone.
