+### Fase 6 — what has been built
+
+**6.1 PWA `injectManifest` migration**
+- `apps/web/src/sw.ts` — minimal custom SW: `precacheAndRoute(self.__WB_MANIFEST)` + `skipWaiting`/`clients.claim`. Named `sw.ts` (not `service-worker.ts`) to dodge SvelteKit's built-in interception (see gotcha #10).
+- `apps/web/vite.config.ts` — switched `@vite-pwa/sveltekit` to `strategies: 'injectManifest'` with `srcDir: 'src'`, `filename: 'sw.ts'`, `injectManifest.globPatterns` for the built shell.
+- `apps/web/src/routes/+layout.svelte` — registers the SW via `onMount() → import('virtual:pwa-register').registerSW({ immediate: true })`. `@vite-pwa/sveltekit` does NOT auto-register; without this call the virtual module is a no-op and `navigator.serviceWorker.getRegistration()` returns `undefined`.
+- `apps/web/tests/e2e/pwa.test.ts` — P-01 (manifest shape) + P-02 (SW registration via `waitForFunction` poll).
+
+**6.2 Manifest + iOS meta tags + placeholder icons**
+- Manifest driven by `vite.config.ts` → `SvelteKitPWA({ manifest: {…} })`. Icons declared 192×192, 512×512, 512×512 maskable. `theme_color: #0f172a`, `background_color: #f7f9fb`, `display: standalone`.
+- `apps/web/static/icons/` — `icon-192.png`, `icon-512.png`, `icon-512-maskable.png`, `icon-180.png` placeholder PNGs (slate background + "C" glyph). Generator: `infra/scripts/generate-placeholder-icons.sh` (ImageMagick). Replace with final artwork before public launch — noted in `static/icons/README.md`.
+- `apps/web/src/app.html` — iOS PWA meta tags: `apple-mobile-web-app-capable`, `apple-mobile-web-app-status-bar-style`, `apple-mobile-web-app-title`, `apple-touch-icon`.
+
+**6.3 Kong rate-limit (invitations only)**
+- `infra/kong.yml` — `rest-v1-invitations` route: `POST /rest/v1/collective_invitations`, rate-limit `hour: 20, policy: local, limit_by: header (Authorization)`. `strip_path: true` on a full-table path sends `/` upstream which PostgREST rejects with `PGRST117`, so the route also carries a `request-transformer` plugin that rewrites the URI back to `/collective_invitations`.
+- `infra/docker-compose.dev.yml` — `KONG_PLUGINS` env var gains `rate-limiting` (was missing).
+- `packages/test-utils/tests/rate-limit.test.ts` — RL-02 only (21st invitation POST = 429). Gated behind `RUN_RATE_LIMIT_TESTS=1` so it's excluded from `just test-all` (Kong counters are shared state). Run via `just test-rate-limit`, which also `--force-recreate`s Kong to reset counters first.
+- **Scope dropped during execution:** Kong rate-limit on `/auth/v1/token` + `/auth/v1/authorize` removed. Reasoning: Keycloak already offers native brute-force protection on the realm (`bruteForceProtected: true`, `maxFailureWaitSeconds: 900`, `failureFactor: 30` in `keycloak/realm-export.json`), and stacking Kong on top throttles legitimate PKCE code exchanges during E2E (the same `/auth/v1/token` endpoint handles both password auth and code exchange — Kong can't distinguish). See `plan/fase-6-deploy-prep.md` §6.3 for the full rationale.
+
+**6.4 JWT rotation + production env template**
+- `infra/scripts/rotate-jwt.sh` — bash script signing HS256 `anon` + `service_role` JWTs with a freshly-generated 48-byte secret via `openssl dgst -sha256 -hmac + base64url`. Prints the three values (`SUPABASE_JWT_SECRET`, `PUBLIC_SUPABASE_ANON_KEY`, `SUPABASE_SERVICE_ROLE_KEY`) for the operator to paste into `.env`. Does NOT touch files.
+- Dev secret rotated as a dry-run of the procedure. `.env` + `apps/web/.env.development` updated together (see `project_env_keys_trap` memory — both files carry `PUBLIC_SUPABASE_ANON_KEY`). Deduped a pre-existing duplicate `PUBLIC_SUPABASE_ANON_KEY=` line in `.env`.
+- `.env.production.example` — committed template with placeholders + rotation cadence note.
+
+**6.5 Lighthouse + RLS audit tooling**
+- `Justfile` — `just lighthouse` recipe (prod build → node server on :3000 → `lighthouse --only-categories=pwa,accessibility,best-practices` → HTML report). Requires `just dev` to be up so the real Supabase stack is reachable.
+- `Justfile` — `just rls-audit` delegates to `infra/scripts/rls-audit.sh`.
+- `infra/scripts/rls-audit.sh` — signs an Eva JWT (non-member of the seed collective) with `SUPABASE_JWT_SECRET` and GETs eight REST endpoints (`collectives`, `shopping_lists`, `shopping_items`, `task_lists`, `tasks`, `notes`, `collective_members`, `collective_invitations`). Complements `rls-audit.test.ts`; all 8 must return `[]`.
+
+**Gotchas discovered during execution (do not remove):**
+
+13. **`strip_path: true` on a full-table Kong route strips too much.** With `paths: [/rest/v1/collective_invitations]` and `strip_path: true`, Kong forwards `/` upstream — PostgREST returns `PGRST117: Unsupported HTTP method: POST` because it tries to route root, not the table. Fix: add a `request-transformer` plugin that `replace.uri: /collective_invitations`. Applies identically to any route where the match path equals the full upstream resource path (as opposed to a prefix match like `/rest/v1/`).
+
+14. **Kong `KONG_PLUGINS` must explicitly list every plugin used in `kong.yml`.** Without `rate-limiting` (or any other non-default plugin) in the comma list, Kong boots with `plugin 'xxx' not enabled; add it to the 'plugins' configuration property`. `infra/docker-compose.dev.yml` currently lists `request-transformer,cors,key-auth,acl,basic-auth,rate-limiting`.
+
+15. **`@vite-pwa/sveltekit` does not auto-register the service worker.** The plugin provides a virtual module (`virtual:pwa-register`, `virtual:pwa-register/svelte`) but you have to call `registerSW()` (or `useRegisterSW()` for Svelte bindings) yourself. Without that call, the SW file is generated + served but never registered, and `navigator.serviceWorker.getRegistration()` returns `undefined`. The canonical place is `apps/web/src/routes/+layout.svelte`'s `onMount()`.
+

+- `icon-512-maskable.png` — 512×512, purpose `"maskable"`. Keep meaningful content inside the central 80% safe zone so iOS/Android rounded-mask crops don't cut the glyph.

 ### Fase 6 — Deploy readiness (PWA + rate-limit + secret rotation)
-**Estado: ⏳ Propuesta**
-**Duración estimada: 3–5 días**
+**Estado: ✅ Completa (2026-04-14)**
+**Duración real: 1 día.**
 **Objetivo: cerrar los ítems diferidos de Fase 4 que bloquean un despliegue público del MVP.**
 
+**Resultado:** 236 tests verdes (34 pgTAP + 140 Vitest integración + 15 Vitest unit + 46 Playwright + 1 rate-limit aislado), RLS audit manual OK, dev JWT rotado con éxito. Scope dropped durante la ejecución: rate-limit de `/auth/v1/token` + `/auth/v1/authorize` retirados — Keycloak ya ofrece brute-force protection nativa (`bruteForceProtected=true`, `maxFailureWaitSeconds=900`, `failureFactor=30`) y aplicar rate-limit adicional en Kong interfería con los intercambios PKCE legítimos durante E2E. El rate-limit crítico (anti-spam de invitaciones) sí se mantiene.
+
 Esta fase cierra los ítems que en Fase 4 se dejaron para "sprint de deploy": PWA real (SW custom, manifest, iconos), rate-limiting en Kong, rotación de JWT, y validación Lighthouse + auditoría RLS manual. Notificaciones push se retiran explícitamente del scope (decisión del 2026-04-14; sin caso de uso actual).
 
 Sigue el patrón TDD donde el cambio es programático (rate-limit, SW registration, manifest served). La auditoría Lighthouse + el chequeo manual de rotación quedan como tareas documentadas — no son test automatizables.

+| `/auth/v1/token` + `/auth/v1/authorize` | — | — | **dropped** — ver nota abajo |
+
+**Nota sobre el scope dropped de auth rate-limit:** el plan original apilaba rate-limits en Kong sobre `/auth/v1/token` (10/min IP) y `/auth/v1/authorize` (30/min IP). Al integrarlo con el flujo real de Playwright se vio que:
+
+1. El PKCE code exchange también golpea `/auth/v1/token` y 10/min es insuficiente para una batería E2E de ~50 logins. Se llena el cupo → 429 → fallos intermitentes.
+2. Brute-force de contraseñas lo protege Keycloak nativamente (`bruteForceProtected=true` en `realm-export.json`, 30 fallos por usuario antes de lockout de 15 min). Esa es la capa correcta.
+3. Añadir rate-limit en Kong duplicaría la protección y lo haría mal — Kong no puede distinguir entre "usuario intentando logear" y "cliente PKCE canjeando su code".
+
+→ Se retira Kong rate-limit de `/auth/v1/*`. El test `RL-01` se eliminó; solo queda `RL-02` (invitaciones).
 
 Kong ships with `rate-limiting` plugin; política `local` (sin Redis) es suficiente para single-instance. Config en `infra/kong.yml`:
