+### Test suite — what has been built
+
+- `packages/test-utils/` — shared test infrastructure (Vitest integration tests)
+  - `package.json` — `@colectivo/test-utils`; depends on `@supabase/supabase-js`, `jose`, `pg`
+  - `vitest.config.ts` — loads root `.env` via `loadEnv`; single-fork mode (no parallelism races)
+  - `src/seed-constants.ts` — fixed UUIDs for all 5 seed users + collective + seed list
+  - `src/supabase-clients.ts` — `createClientAs(userId)` signs HS256 JWT with `SUPABASE_JWT_SECRET`; `createAdminClient()` uses service role key
+  - `src/db-helpers.ts` — `sql()` via raw `pg` Pool for direct DB manipulation (bypasses RLS); used to set `deleted_at = 8 days ago` etc.
+  - `tests/rls-isolation.test.ts` — F-series: Eva (non-member) sees zero rows, all writes blocked
+  - `tests/rls-collective.test.ts` — B-series: collective read/update/invite by role
+  - `tests/rls-lists.test.ts` — C-series: list CRUD, soft-delete, trash window, cross-collective isolation
+  - `tests/rls-items.test.ts` — D-series: item CRUD by role, cross-collective item isolation
+  - `tests/rls-frequency.test.ts` — E-series: frequency read-only + trigger populates on INSERT
+- `supabase/tests/*.sql` each start with `CREATE EXTENSION IF NOT EXISTS pgtap;` so they're idempotent on a fresh DB
+  - `001_accept_invitation.sql` — `accept_invitation()` happy path + not_found / expired / already_used; uses `set_config('request.jwt.claim.sub', …)` to set `auth.uid()` for the test session, and looks up by `token` (not `id`)
+  - `002_item_frequency_trigger.sql` — trigger normalizes name with `lower(trim(...))` and increments `use_count` on repeat INSERTs. RLS write-blocks are covered by the Vitest suite instead (postgres superuser bypasses RLS here)
+  - `003_promote_on_admin_leave.sql` — deletes a synthetic admin from `public.users` to fire the `BEFORE DELETE` trigger and asserts the oldest remaining member is promoted
+- `apps/web/playwright.config.ts` — Playwright config; `globalSetup` is a Keycloak health check (not a session cache), `reuseExistingServer: true`
+- `apps/web/tests/fixtures/users.ts` — seed user constants (Ana, Borja, Carmen, David, Eva)
+- `apps/web/tests/fixtures/login.ts` — `loginAs(page, user)` runs the real OAuth flow (Keycloak → GoTrue PKCE) and waits for the session token to land in localStorage. Each test that needs auth calls this in `beforeEach`; cached `storageState` is NOT used (see gotcha #12)
+- `apps/web/tests/e2e/auth.test.ts` — A-series: unauthenticated redirect, full login, collective visible in sidebar, sign-out, guest login
+- `apps/web/tests/e2e/lists.test.ts` — C-series: create (with reload-persistence check), soft-delete → appears in trash drawer, archive, guest read-only
+- `apps/web/tests/e2e/items.test.ts` — D-series: seed list renders, add item (with reload-persistence check), toggle check, desktop-hover delete, frequency suggestions, guest read-only

 9. **CSS custom properties use RGB triplets — always use `rgb()`, never `hsl()`.** All design tokens in `app.css` store values as space-separated RGB triplets (e.g. `51 65 85`). Using `hsl(var(--token))` interprets the first value as a hue degree — `hsl(51 65% 85%)` renders as light yellow, not slate-700. The Tailwind config and any `background-color`/`color` declarations in `app.css` must use `rgb(var(--token) / <alpha>)`.
 
+11. **Supabase JS v2 + SvelteKit: `loadUserCollectives` (or any PostgREST query) inside `onAuthStateChange` must be deferred with `setTimeout(..., 0)`.** GoTrue's default `navigator.locks`-based auth lock is held while the `onAuthStateChange` callback runs. Any `supabase.from(...).select(...)` called inside that callback calls `getAccessToken() → getSession() → initializePromise → _acquireLock`, which is the same lock that's already held by the emit logic — the promise never resolves, the query hangs forever. Fix: schedule the query off the callback's microtask chain with `setTimeout(async () => { await loadUserCollectives(session.user.id); … }, 0)`. As a defensive extra, `$lib/supabase` passes a pass-through `auth.lock` option so the whole lock path is a no-op. Both are needed: without the defer, some browsers still deadlock; without the pass-through, others do. Removing either one breaks the Playwright E2E suite.
+
+12. **Playwright auth: do not cache Supabase sessions via `storageState`. Do a live Keycloak login per test.** `browser.newContext({ storageState })` restores localStorage + cookies, but Supabase's `_recoverAndRefresh` does not reliably re-fire `INITIAL_SESSION` from a restored context — the page hydrates without triggering `onAuthStateChange`, so `currentUser` / `currentCollective` stay empty. The working pattern is `await loginAs(page, USERS.ana)` at the top of each test (see `tests/fixtures/login.ts`), which exercises the real OAuth flow and waits for the session token to land in localStorage before returning. Adds ~1s per test but is deterministic.
+
 10. **PWA service worker: do not use `injectManifest` with a file named `service-worker.ts`.** SvelteKit intercepts any file at `src/service-worker.[jt]s` and enforces a hard restriction: only `$service-worker` and `$env/static/public` may be imported — Workbox modules are blocked. With `injectManifest`, `@vite-pwa/sveltekit` tries to find the compiled SW output at `.svelte-kit/output/client/service-worker.js`, but SvelteKit never produces it (compilation fails on the blocked imports). Fix for Fase 1–2a: use `generateSW` strategy (plugin auto-generates the SW, no custom source needed). Fix for Fase 2b when a custom SW is needed: name the file `src/sw.ts` — SvelteKit does not recognise it as a service worker — and set `strategies: 'injectManifest'`, `filename: 'sw.ts'` in `vite.config.ts`.

+
+## Metodología por fase (TDD)
+
+Desde la Fase 1 en adelante, cada fase está estructurada así:
+
+1. **`X.0 Tests primero`** — se escriben los tests (Vitest + pgTAP + Playwright) que definen el éxito de la fase, **antes** de cualquier implementación.
+2. **`X.1 … X.N`** — implementación en el orden que mejor sirva a los tests.
+3. **`X.Z Verificación final`** — `just test-all` debe devolver 0 failures. Sólo entonces la fase se considera cerrada.
+
+Las fases ya cerradas (0, 1, 2a) reflejan este patrón retroactivamente: la sección `X.0` enumera los tests que hoy cubren la fase, y `X.Z` confirma que `just test-all` pasa.
+

 ### Fase 2b — Sincronización en Tiempo Real y Modo Compra
+**Estado: ⏳ Pendiente**
 **Duración estimada: 2–3 semanas**  
 **Objetivo: el diferencial del producto. Es la fase más compleja técnicamente.**
 
+Esta fase sigue TDD: **primero los tests, al final la verificación.** Ninguna tarea de implementación se da por hecha hasta que todos los tests pasan (`just test-all`).

+- [ ] `realtime-presence.test.ts` — dos clientes (Ana + Borja) entran en la misma lista; ambos aparecen en el canal Presence; salir del canal elimina al usuario
+- [ ] `realtime-postgres-changes.test.ts` — Ana hace INSERT/UPDATE/DELETE en `shopping_items`; Borja (suscrito al canal) recibe el evento en < 1s
+- [ ] `realtime-isolation.test.ts` — Ana y David (guest del mismo colectivo) están suscritos a la misma lista; Eva (fuera del colectivo) NO recibe nada aunque intente suscribirse (RLS en `supabase_realtime.broadcast`)
+- [ ] `sync-queue.test.ts` (unit, con mock de `idb`) — cada mutación escribe en `pending_ops` antes de llamar a Supabase; al recibir la confirmación se elimina de la cola; si falla se mantiene para reintento
+- [ ] `sync-flush.test.ts` (unit) — al disparar el evento `online` se flushea la cola respetando el orden original; colisiones resueltas con last-write-wins

+- [ ] `session.test.ts` — S-01: abrir Modo Compra en `/lists/[id]/session` muestra el layout full-screen sin sidebar
+- [ ] `session.test.ts` — S-02: marcar un ítem lo mueve a la sección CHECKED con animación (no se duplica)
+- [ ] `session.test.ts` — S-03: botón "Finish shopping" → confirmación modal → lista pasa a `completed`, redirige a `/lists`
+- [ ] `realtime.test.ts` — R-01 (dos contextos de navegador): Ana crea ítem, Borja lo ve sin refrescar la página
+- [ ] `realtime.test.ts` — R-02: Ana marca ítem, avatar de Borja aparece en el indicador de Presence
+- [ ] `offline.test.ts` — O-01: con `context.setOffline(true)`, añadir/marcar ítems sigue funcionando localmente y aparece el banner "sin conexión"
+- [ ] `offline.test.ts` — O-02: al volver online (`setOffline(false)`), los cambios pendientes se sincronizan y el banner desaparece
