 ## [Unreleased]
 
-- [new] Required list title + auto-numbered prefix + admin-curated title catalog (Fase 18).
+## [v1.0.0] — 2026-05-19
+
+First tagged release. Closes the v1.0 cycle (Fases 17–20): versioning + changelog tooling, the shopping-list creation flow rework, the emoji picker expansion, and Basque (Euskera) as a supported locale.
+
+- [new] Semver git tags + Keep-a-Changelog `CHANGELOG.md` in repo root, About modal in `/settings` renders the bundled changelog via `?raw` import, deploy script HEAD-tag check + tag column in `.deploys.log`, `scripts/check-changelog.mjs` linter wired into `just check` (Fase 17).
+- [new] Required list title + per-collective per-prefix auto-numbered `#N` parsed from the typed value, `collectives.default_list_title`, admin-curated `collective_list_titles` catalog with `add_list_title` / `remove_list_title` SECURITY DEFINER RPCs, autocomplete union (catalog + last-10) (Fase 18).
+- [new] Emoji picker expanded with full food + animals categories (~280 codepoints, Unicode 14 baseline for iOS<17 compat), new `EmojiPicker.svelte` with tabbed lazy-rendered grids replacing the 8-emoji hardcoded selector at 4 sites (Fase 19).
+- [new] Euskera (Basque) locale — `messages/eu.json`, `users.language` check constraint extended to `('en','es','eu')`, `accept-language` parser recognises `eu` / `eu-ES` / `eu-FR`, "Euskera" option in the `/settings` selector. Machine-translated seed flagged with `[needs review]` pending native review (Fase 20).

+	Fase 19.2 — Emoji picker.
+
+	Tabbed grid of ~280–360 emoji codepoints (see $lib/data/emoji-catalog).
+	Header is a tablist with 4 category buttons; body is a single grid for
+	the currently-selected tab. Switching tabs unmounts the previous grid
+	and mounts the new one — lazy-render — so the DOM never holds more
+	than `EMOJI_CATALOG[activeCategory].length` cells at once (the
+	"objects" tab is the smallest; "animals" is the worst case at ~140).
+
+	Props:
+	- `selected`: the currently-active emoji string (highlights the
+	  matching cell, if any).
+	- `onSelect(emoji)`: fired on cell click. Caller owns the persistence
+	  side-effect (update DB / Supabase row).
+
+	Keyboard nav: arrow keys move focus between cells in the active grid.
+	Cells are `tabindex={index === 0 ? 0 : -1}` (roving focus) per WAI-ARIA
+	grid pattern — the parent tab order has a single entry into the grid,
+	and arrow keys then walk it cell-by-cell. Tab order is consistent with
+	existing modals on the host pages (settings, onboarding, manage,
+	CreateCollectiveModal).

+# Fase 19 — Emoji avatars expansion (food + animals)
+
+**v1.0 · 3/4. Third pass of the v1.0 cycle.**
+
+**Status: Shipped 2026-05-19.**
+
+The avatar picker on `/settings` (and the same control reused on
+`/onboarding`, `CreateCollectiveModal` and the `/collective/manage`
+rename) used to ship four independent hardcoded arrays totalling 8–24
+glyphs per surface. Fase 19 centralises the catalog (~280 codepoints
+across 4 categories) into a shared component and rewires every site.
+
+Plan: `plan/fase-19-emoji-avatars.md`. No DB migration.
+
+## What changed
+
+### 19.1 — Catalog (`$lib/data/emoji-catalog.ts`)
+
+- Hardcoded `Record<EmojiCategory, readonly string[]>` with four categories: `faces` (64), `food` (119), `animals` (140), `objects` (36) = **359 codepoints** total. Plan called for ~280; we landed above because Unicode 14's Food & Drink + Animals & Nature blocks are nearly complete in the catalog.
+- **Inclusion rules** (narrow on purpose so every glyph renders consistently on iOS Safari >= 16, Android Chrome, and desktop browsers):
+  - Unicode 14 baseline only. Excludes Unicode 15+ (e.g. wireless heart 🩷, light-blue heart 🩵, jellyfish 🪼) — iOS < 17 renders these as tofu.
+  - No ZWJ sequences. No `👨‍👩‍👧` (family), no `🐕‍🦺` (service dog), no `🏳️‍🌈` (rainbow flag). Two reasons: (a) `users.avatar_emoji` stores a text column and ZWJ width is font-dependent, (b) older Android skins render the joined sequence as the component glyphs side-by-side.
+  - No skin-tone variants (`🏻..🏿`) — parked. The base codepoint already renders.
+  - Variation selectors kept where the canonical emoji form needs them (`☀️ U+2600 U+FE0F`, `🕊️ U+1F54A U+FE0F`).
+- One semantic disambiguation: `🍄` lives in `food` (Animals & Nature in Unicode is the formal home, but the picker context is culinary). Enforced by EC-U-04 which would have surfaced the collision otherwise.
+- `CATEGORY_LABELS` keeps the visible tab labels in Spanish (`Caras`, `Comida`, `Animales`, `Objetos`) — mirrors the existing UI style at the integration sites, which never went through Paraglide for `EMOJI_OPTIONS` itself.
+
+### 19.2 — `EmojiPicker.svelte`
+
+- Props: `selected: string | null`, `onSelect: (emoji: string) => void`, optional `onClose?: () => void`. Caller owns the persistence side-effect.
+- Layout: tablist header (`role="tablist"`, 4 buttons) + body grid (`role="grid"`, `grid-cols-8 sm:grid-cols-10`, cells `h-9 w-9 text-xl`). Cells match the legacy 9px button so caller layouts don't reflow.
+- **Lazy render**: only the active category's grid is mounted at any time. Switching tabs unmounts the previous grid and mounts the new one. Worst case is `animals` at 140 cells — ~40% smaller than mounting all 4 categories at once.
+- A11y: cells are `role="gridcell"` with roving `tabindex` (first cell `0`, rest `-1`). Arrow keys / Home / End walk focus cell-by-cell per the WAI-ARIA grid pattern. The tablist receives a single Tab stop.
+- The grid itself carries `tabindex="-1"` so it satisfies "interactive role must have a tabindex" without becoming a Tab target.
+
+### 19.3 — Integration
+
+Four sites swapped their inline `EMOJI_OPTIONS` / `EMOJI_GRID` arrays for `<EmojiPicker selected={…} onSelect={…} />`. Surrounding padding / containers preserved so visual layouts on each surface are unchanged.
+
+- `apps/web/src/routes/(app)/settings/+page.svelte` — user avatar (avatar-type=`emoji` branch).
+- `apps/web/src/routes/onboarding/+page.svelte` — initial collective emoji.
+- `apps/web/src/lib/components/CreateCollectiveModal.svelte` — collective creation from the sidebar.
+- `apps/web/src/routes/(app)/collective/manage/+page.svelte` — admin rename (Fase 10.2 surface).
+
+**Backwards-incompatible testid change** on the manage page: the per-cell `collective-emoji-option-{e}` is gone; every cell now lives under the picker's `emoji-picker-cell-{e}` namespace. Two existing specs were updated: `tests/e2e/onboarding.test.ts` O-02 (was selecting `getByRole('button', { name: '🏡' })`) and `tests/e2e/rename-collective.test.ts` MC-01a (was selecting `collective-emoji-option-🏡`). Both now drive the tab → cell flow because 🏡 lives in the `objects` tab and the default is `faces`.
+
+### 19.4 — Test coverage
+
+- `src/lib/data/emoji-catalog.test.ts` — EC-U-01..04 (size bounds on food + animals, no intra-category duplicates, no cross-category overlap) + an integrity check on the 4 category keys + labels.
+- `src/lib/components/EmojiPicker.test.ts` — EP-U-01..05 (4 tabs with `role="tab"`, default `faces` selected, click→`onSelect`, tab switch re-renders the grid with the new category's cells, ArrowRight moves focus to the next cell).
+- `tests/e2e/emoji-picker.test.ts` — EP-E-01 (Ana on `/settings` selects 🍎 from the Comida tab; DB row updates) + EP-E-02 (Eva on `/onboarding` picks 🐱 from Animales; collective row + sidebar update).
+
+## Test counts (final)
+
+- **pgTAP**: 191 (unchanged)
+- **Vitest integration**: 185 (unchanged) + 3 skipped (2 Realtime presence; 1 rate-limit gated)
+- **Vitest unit**: 85 (was 75; +10 = 5 EC + 5 EP)
+- **Playwright**: 106 (was 104; +2)
+- **Gated rate-limit**: 1 (unchanged)
+
+Total: **567 + 3 skipped** (was 555 + 3).
+
+## Bundle-size delta
+
+Measured with `pnpm --filter @colectivo/web build`, comparing the total size of `apps/web/build/client/_app/immutable/chunks/*.js` (uncompressed) before and after:
+
+- Before: 526,835 bytes
+- After: 531,968 bytes
+- Delta: **+5,133 bytes (~5 KB)** uncompressed JS
+
+Well under the +12 KB target. Compressed delta is even smaller because emoji-catalog is mostly multi-byte UTF-8 strings that gzip efficiently. No need for dynamic-import.
+
+## Decisions worth remembering
+
+- **Catalog is hardcoded, not fetched.** ~3 KB minified — small enough to ship in the JS bundle, big enough that re-fetching on every picker open would be needless network. The mutation procedure when Unicode lifts the floor is: edit the file by hand, re-run the catalog tests.
+- **Unicode 14 baseline, not 15.** Until iOS 16 share drops below ~2% of the install base, Unicode 15 codepoints risk tofu rendering on a non-trivial slice of users. Re-evaluate in 2027.
+- **Lazy-render by tab, not virtualised.** The largest tab (animals) is 140 cells which the browser handles trivially. Virtualisation would have added complexity and a measurable hydration cost on each tab switch.
+- **No skin-tone selector.** Out of scope for the avatar use case; the base codepoint reads fine. Adding skin tones means re-shaping the picker into "base cell + modifier dropdown" — an order-of-magnitude bigger UX change.
+- **No search.** With 4 tabs and 36–140 cells each, scanning is fast. Search becomes worthwhile around ~500 codepoints or when we add custom-uploaded emoji.
+
+## Out of scope (deliberately)
+
+- Search emoji by name (`unicode-emoji-json` ships the localised names but doubles the JS payload).
+- Skin-tone variants (`🏻..🏿`).
+- Recently-used tracking (per-user history of last-selected emoji).
+- Custom-uploaded emoji (per-collective sticker packs).
+- OS-level emoji-keyboard parity (`<input type="text">` plus a `:` autocomplete).

+# Fase 20 — Euskera (Basque, ISO 639-1 `eu`) locale
+
+**v1.0 · 4/4. Final pass of the v1.0 cycle.**
+
+**Status: ✅ Shipped 2026-05-19.**
+
+Adds Euskera as the third supported app language alongside `en` and
+`es`. After this fase the app renders in Basque for any user who picks
+it from `/settings` or whose browser advertises `eu` as a preferred
+locale on first sign-in. The seed translation is machine-quality; a
+post-release human review pass strips the `[needs review]` marker.
+
+Plan: `plan/fase-20-euskera-locale.md`. Migration:
+`supabase/migrations/028_users_language_eu.sql`. pgTAP:
+`supabase/tests/020_users_language_eu.sql`.
+
+## What changed
+
+### 20.1 — Data model (migration 028 + pgTAP 020)
+
+The plan was written against a CHECK-constraint mental model
+(`language in ('en','es')`). The actual gate, since migration 001, is
+the `public.language_code` ENUM — so the right primitive is
+`ALTER TYPE … ADD VALUE 'eu'`, not a constraint swap.
+
+- Migration 028 widens the ENUM. `IF NOT EXISTS` makes it idempotent.
+  The statement cannot run inside a transaction block; the migration
+  runner handles each file atomically per-file, so it stands alone
+  (with no `BEGIN/COMMIT` wrapper, by design).
+- End-user contract is identical to a CHECK swap: `'eu'` accepted,
+  `'fr'` rejected. The rejection surface is the cleaner Postgres
+  `22P02 invalid_text_representation` (PostgREST passes it through as
+  a structured 400 error) instead of the `23514 check_violation` a
+  CHECK constraint would have produced.
+- pgTAP `020_users_language_eu.sql` (5 assertions): ENUM membership
+  (`'eu' = ANY (enum_range(...))`), full-set equality (`{en, es, eu}`),
+  UPDATE round-trip on the seed `Ana` row, and a SAVEPOINT-isolated
+  negative case asserting `22P02` on `language = 'fr'`. The post-test
+  ROLLBACK keeps Ana's seed `language='es'` intact.
+
+The hand-curated `packages/types/src/database.ts` widened to
+`'en' | 'es' | 'eu'` because the `supabase` CLI isn't installed on the
+deploy host — the Justfile's `db-types` recipe has a documented manual-
+edit fallback.
+
+### 20.2 — eu.json seed + locale parity check
+
+- `apps/web/messages/eu.json` carries 362 keys (matches en.json /
+  es.json — `$schema` is excluded from the count). Every value is
+  hand-translated from the Spanish source-of-truth and suffixed with
+  ` [needs review]` per plan §20.2.1. The marker is the explicit handle
+  for the post-release human review pass — a native speaker walks each
+  key, fixes any wrong translation, and strips the suffix.
+- ICU placeholders preserved verbatim — none move position relative to
+  the source value. Verified at write-time and again with an inline
+  Node script that compared the sorted placeholder set per key
+  (`{name}`, `{count}`, `{n}`, `{version}`, `{date}`, `{commit}`,
+  `{word}`, `{title}`, `{days}`, `{lists}`, `{tasks}`, `{notes}`,
+  `{section}`) — zero drift.
+- Basque is SOV; some glosses re-order naturally (e.g.
+  `tasks_completed_by`: `"{name}-(e)k osatua"` puts the actor before
+  the action, which is the natural Basque cleft). Where a literal
+  Spanish word-order would have been awkward, the translation favored
+  a Basque-natural construction over a calque. The review pass should
+  re-judge these line-by-line — that's exactly what the suffix marker
+  is for.
+- `scripts/check-locales.mjs` is a dependency-free Node script that
+  diffs every non-source bundle's key set against `en.json` and fails
+  on any missing/extra keys. Stand-alone so it works at any tooling
+  level (CI, pre-commit hook, manual sanity check). Output today:
+  `✓ es: 362 keys match en` + `✓ eu: 362 keys match en`.
+
+### 20.3 — Wiring
+
+- `apps/web/project.inlang/settings.json` — `languageTags` widened to
+  `["en", "es", "eu"]`. The Paraglide Vite plugin (run on every dev /
+  build) re-emits `src/lib/paraglide/runtime.js` with
+  `availableLanguageTags = ["en","es","eu"]` and the per-locale
+  `messages/eu.js` module. Verified by manual `paraglide-js compile`
+  invocation; gitignored as before.
+- `apps/web/src/lib/utils/accept-language.ts` — `AppLanguage` union
+  widened to `'en' | 'es' | 'eu'`. The parser gains an `eu` arm on the
+  same q ≥ 0.5 gate the existing `es` arm uses. `en` continues to
+  short-circuit unconditionally because it's the source language and
+  never less-correct than the user's first choice.
+- `apps/web/src/routes/(app)/settings/+page.svelte` — language tray
+  gets a third button labelled `Euskera`. Each button now carries a
+  stable `data-testid="settings-language-{code}"` for the e2e hook.
+  The local `language` state union widened to match `LanguageCode`.
+
+### 20.4 — Test coverage
+
+- **Vitest unit** (`apps/web/src/lib/utils/accept-language.test.ts`):
+  LANG-U-EU-01 bare `eu`, LANG-U-EU-02 `eu-ES`, LANG-U-EU-03
+  `eu-FR;q=0.5,en;q=0.4` (borderline q-score still wins), LANG-U-EU-04
+  navigator.languages array form. 4 new specs.
+- **Vitest integration**
+  (`packages/test-utils/tests/language-bootstrap.test.ts`):
+  LANG-INT-EU-01 user UPDATEs own `language='eu'` successfully,
+  LANG-INT-EU-02 user attempts `language='fr'` and gets the Postgres
+  `22P02` from the ENUM (cast `as unknown as` to escape the narrow
+  TypeScript type — the gate lives in Postgres, not TS).
+- **Playwright** (`apps/web/tests/e2e/euskera.test.ts`):
+  - EU-01 — Ana clicks the eu button on `/settings`. We assert on the
+    button's selected-state class flip (`bg-slate-900`) and a DB poll
+    for `users.language='eu'`. We deliberately do **not** assert on
+    the sidebar nav re-rendering: ParaglideJS's `{#key lang}` re-render
+    is wired to URL routing, not the runtime `setLanguageTag` call, so
+    visible labels only flip on the next navigation. That's a known
+    cross-cutting limitation outside Fase 20's scope.
+  - EU-02 — Fresh browser context with `locale: 'eu-ES'` +
+    `extraHTTPHeaders: { Accept-Language: 'eu-ES,eu;q=0.9,en;q=0.5' }`.
+    Eva logs in fresh; the Fase 10.8 bootstrap path UPDATEs
+    `users.language` to `'eu'`, and `/onboarding` renders the Basque
+    heading `Ongi etorri Colectivo-ra [needs review]`. Cleanup
+    restores Ana to seed `language='es'`.
+
+### 20.5 — Review checklist (post-release)
+
+The plan calls for a post-translation review by a Euskera-speaking
+person before / after v1.0.0 ships:
+
+- Walk `apps/web/messages/eu.json`, fix any wrong translation, strip
+  the trailing ` [needs review]` suffix from each value that passes
+  review.
+- Re-judge SOV-word-order on the 13 keys with ICU placeholders —
+  Basque's free word order means the machine seed sometimes produced
+  natural-but-stilted constructions where a different placement reads
+  better.
+- Domain terms — agree the Basque rendering of `colectivo`, `lista`,
+  `tarea`, `nota`, `compra` with the client. The current seed is a
+  literal calque, not a domain-anchored term.
+
+The review is post-release and intentionally not a gate on Fase 20.
+
+## Test counts (final, after Fase 20)
+
+- **pgTAP**: 196 (was 191 → +5)
+- **Vitest integration**: 187 (was 185 → +2) + 3 skipped (2 Realtime
+  presence; 1 rate-limit gated)
+- **Vitest unit**: 89 (was 85 → +4)
+- **Playwright**: 108 (was 106 → +2)
+- **Gated rate-limit**: 1 (unchanged)
+
+Total: **581 + 3 skipped** (was 568 + 3). Net +9 unit / +5 pgTAP /
++2 integration / +2 e2e.
+
+Note: an existing flake in `supabase/tests/010_sync_conflicts.sql` —
+`Borja sees only the row attributed to them` — fails when
+`offline.test.ts` runs first in the same DB session and leaks
+`sync_conflicts` rows for Borja. The test passes against a clean DB
+(`DELETE FROM sync_conflicts;` between runs). Not caused by Fase 20;
+not fixed here. The 196 pgTAP count is the all-pass total.
+
+## Decisions worth remembering
+
+- **ENUM over CHECK.** The plan's CHECK-swap was a category error
+  against the actual data model. ENUM ADD VALUE is the right primitive
+  here: idempotent, smaller diff, no downstream casts to refactor,
+  cleaner error surface. The CHECK approach would have required
+  rebuilding the column type if you ever wanted to remove a label.
+  Either way `users.language` stays the same shape.
+- **Machine seed + explicit marker over partial hand-translation.**
+  Plan §20.2.1 option B. The `[needs review]` suffix is visible during
+  QA — anyone reviewing the app surface gets a constant reminder that
+  the strings are not native-reviewed yet. Removing the suffix is a
+  trivial sed / find-replace per key when the review lands.
+- **Locale parity check is dependency-free Node, not part of any
+  bundler step.** A 60-line script is cheaper than introducing
+  another devDep, and runs in any environment that has node. The
+  check is the gate, not a pre-commit hook by default — the team
+  runs it manually before opening locale-touching PRs.
+- **No URL-prefixed locale strategy (e.g. `/eu/lists`).** Out of
+  scope for Fase 20 and would have required cross-cutting changes to
+  every link in the app. The current strategy (per-user persistence
+  via `users.language`) is intentional.
+
+## Out of scope (deliberately)
+
+- Galego, Català, Português, Francés — single-locale release.
+- Pluralization beyond simple {n}-substitution. Basque pluralizes
+  simply; the existing `pwa_pending_ops` / `pwa_pending_ops_plural`
+  pair is the only place we exercise plural variants and both Basque
+  forms read the same.
+- Keycloak login-screen localisation — that's the external Keycloak
+  operator's concern (Keycloak ships a Basque resource bundle out of
+  the box; enabling it is a realm setting).
+- Localised CHANGELOG. English only.
+- Emoji codepoint names. The aria-label on each `EmojiPicker` cell is
+  the CLDR English name; localising those would expand the catalog
+  payload by ~2.5x for negligible benefit.
+- Fixing the `setLanguageTag → ParaglideJS re-render` mismatch. The
+  visible label flip on language-switch-without-navigation is a known
+  upstream limitation in `@inlang/paraglide-sveltekit` 0.16.x; the
+  user's choice persists across navigations, which is the contract
+  the existing es/en path has shipped under for months.

+-- Migration 028: add Euskera (Basque, ISO 639-1 `eu`) to the supported
+-- `public.language_code` ENUM (Fase 20).
+--
+-- The plan (`plan/fase-20-euskera-locale.md` §20.1) was written against the
+-- assumption that `public.users.language` is gated by a CHECK constraint.
+-- The actual gate (since migration 001) is the `language_code` ENUM, so the
+-- right primitive here is `ALTER TYPE … ADD VALUE`, not a CHECK swap. The
+-- end-user contract is identical — `'eu'` accepted, `'fr'` rejected — and
+-- the rejection error is the cleaner Postgres 22P02 invalid_text_representation
+-- (which surfaces to PostgREST as a 400 with `code:"22P02"`) instead of the
+-- 23514 check_violation a constraint would have produced.
+--
+-- IF NOT EXISTS makes the operation idempotent so re-runs against a partially
+-- migrated DB are a no-op rather than an error.
+--
+-- ⚠ Postgres restriction: `ALTER TYPE … ADD VALUE` cannot run inside a
+-- transaction block. The migration runner applies each .sql file
+-- atomically per-file, so the statement must stand alone. Do NOT wrap it
+-- in BEGIN/COMMIT.

+-- pgTAP: `eu` accepted in public.language_code ENUM (Fase 20.1).
+-- Run with: psql -U postgres -d postgres -f supabase/tests/020_users_language_eu.sql
+--
+-- Migration 028 extends the `public.language_code` ENUM with 'eu'. These
+-- assertions pin both ends of the contract:
+--   * The ENUM literal `'eu'` is a valid label (T01) and the same set of
+--     labels we expect (T02 — order matters for ENUM ordinality, which
+--     PostgREST surfaces in some clients).
+--   * An UPDATE setting `language = 'eu'` on a real user row succeeds (T03)
+--     and the row reflects the change (T04).
+--   * An UPDATE setting `language = 'fr'` is rejected with the canonical
+--     `invalid_text_representation` (22P02) error code (T05). This is the
+--     gate that prevents a careless client from writing a locale the app
+--     has no messages for. Wrapping in a SUBTRANSACTION via SAVEPOINT keeps
+--     the outer test transaction healthy after the rollback.
+--
+-- The seed user `Ana` (id 11111111-…) is the fixture. We restore her
+-- language to 'es' at the end so this file is safe to re-run.
