`CreateListModal.svelte` is the new entry point for "New list" — opens
on the masthead button click, prefills the input with
`currentCollective.default_list_title` (Fase 18.3.1), shows an inline
autocomplete dropdown via `fetchTitleSuggestions`, and renders a
"Sugerencia: Compra #6" chip when (a) the typed value exactly matches a
catalog-curated prefix case-insensitively and (b) `computeNextNumber`
resolves a value (Fase 18.3.2). Submit is disabled while the trimmed
value is empty or creation is in flight (Fase 18.3.3). On submit, if the
catalog match still holds, the modal auto-suffixes "#N" before
inserting and the lists page shows a transient toast confirming the
final name (Fase 18.3.4).
The prefill effect is gated by a `wasOpen` edge-tracker — a naive
`$effect(() => { if (open) value = default })` re-runs whenever
`$currentCollective` updates (e.g. a realtime UPDATE landing after the
user typed something), which clobbered the typed value and froze the
submit button as disabled. The edge guard limits the prefill to the
false→true transition.
`/lists/+page.svelte`: the masthead "New list" button now opens the
modal instead of calling `createList(collective, '', user)` and goto-ing
to the detail page for inline rename. The legacy flow was nice for
quick creates but couldn't enforce a required title or surface the
catalog. Existing per-list actions are unchanged.
15 new i18n strings (en + es) for the modal, the suggestion chip, the
auto-numbered toast, and the manage-page subsection that ships in the
next commit.
Updated existing e2e specs: `lists.test.ts`'s `createList()` helper +
the C-13 guest path now drive the modal instead of the legacy
placeholder input; `session.test.ts` S-03 uses the modal for the
fresh-list setup. New `tests/e2e/list-title-flow.test.ts` adds LTF-01
(default prefill end-to-end with a Supabase-driven setDefaultListTitle
since the manage UI lands in the next commit) and LTF-03 (empty input
keeps submit disabled, even with whitespace).
Tests: 4 lists + 3 session + 2 new LTF specs all green (9/9).

Remove the sticky bottom create input from /lists. The masthead now hosts
a primary "New list" button next to the Trash icon, styled identically to
the "New note" button on /notes. Click → createList with an empty name →
goto /lists/[id], where a prominent editable title input (above To buy /
Checked) autosaves on blur / input with a 500 ms debounce.
Changes
apps/web/src/routes/(app)/lists/+page.svelte
- remove `newListName`, `nameInput`, `handleKeydown`
- remove the absolute-positioned sticky bottom block
- handleCreate now creates with name = '' and navigates to the detail
- actions snippet gains the primary New list button; Trash button
demoted to ghost icon
apps/web/src/routes/(app)/lists/[id]/+page.svelte
- new listName / scheduleNameSave / flushNameSave state (mirrors the
/notes editor pattern)
- big editable title <input> at top of content, autosaves on blur
via renameList
- contextual header h1 trimmed to a secondary caption-size preview
on mobile (so the user still sees the list name at the top)
- flushNameSave on component destroy so unsaved renames commit
apps/web/messages/{en,es}.json: lists_new_list = "New list"/"Nueva lista"
Tests
apps/web/tests/e2e/lists.test.ts: createList helper now clicks the
button, fills the title input, blurs, waits for autosave, and goes
back to /lists to present the same "list-is-on-the-overview" state
that C-11 / C-12 expect. C-07 picks up the reload check.
apps/web/tests/e2e/session.test.ts: S-03 mirrors the new flow for its
fresh-list setup.
Verification
just test-e2e → 40 passed, 2 skipped (swipe-delete .skip remains).

Fase 2b closes the critical-path product differentiator. Two sessions on the
same list see each other's changes in real time, mutations survive network
drops and sync when reconnected, and a dedicated full-screen shopping view
optimises the in-store experience.
2b.1 Realtime
- `$lib/stores/realtimeSync.ts` wraps `postgres_changes` with an `applyItemEvent`
reducer (INSERT/UPDATE/DELETE → next items[]) and a `subscribeToList` helper
that awaits the SUBSCRIBED handshake before returning
- `/lists/[id]` subscribes in onMount, unsubscribes in onDestroy. Uses a
`pendingTempIds` set to deduplicate own-mutation echoes against optimistic
rows (matches by name+created_by+sort_order)
- Client-generated UUIDs for new inserts make the path idempotent: if the
server response is lost and we retry, the second POST hits PK-conflict
which the queue treats as success
- CHECKED section div now carries role="listitem" so Playwright locators
follow the item across sections
2b.2 Offline queue
- `$lib/sync/queue.ts` — SyncQueue class backed by IndexedDB (idb), FIFO flush,
MAX_ATTEMPTS=5 retry budget, PK-conflict-as-success short-circuit
- `$lib/sync/index.ts` — app-wide singleton, window.online listener flushes
automatically, hydrateSyncState() at page load restores pendingOpsCount
- `$lib/stores/syncStatus.ts` — derived store (offline | syncing | synced)
tracking navigator.onLine + queue depth
- SyncBanner component renders the offline/syncing indicator in the detail
and session views
- handleAdd enqueues on failure instead of reverting, so an offline mutation
keeps its optimistic row and syncs on reconnect
2b.3 Modo Compra
- `/lists/[id]/session/+page.svelte` — full-screen overlay (fixed inset-0
z-50) that covers the sidebar while keeping the normal auth routing.
56×56 toggles, flip animation shuffling items between TO BUY / CHECKED,
Finish Shopping confirmation modal → completeList → goto('/lists')
- Link from `/lists/[id]` header (data-testid=start-session) with the
new `list_start_session` message
Testing infra
- apps/web gets its own Vitest config (jsdom + fake-indexeddb/auto) and a
new `pnpm test:unit` script. `just test-all` now chains pgTAP → integration
→ unit → e2e so a single command is the gate.
- packages/test-utils/tests/sync-queue.test.ts (placeholder scaffold) removed —
replaced by `apps/web/src/lib/sync/queue.test.ts` co-located with the module
Totals: 103 tests green
16 pgTAP
59 Vitest integration (in packages/test-utils)
6 Vitest unit (in apps/web — the SyncQueue)
22 Playwright E2E (5 auth + 4 lists + 6 items + 2 realtime + 2 offline + 3 session)
2 skipped (realtime-presence — upstream bug, unchanged)
Documented in plan/fase-2b and CLAUDE.md.

Extend the 2b.0 red-phase coverage: presence, RLS isolation, offline-queue
contract, and Playwright scaffolds for the shopping-session UX. Only the
presence test is blocked on an upstream Realtime bug (documented below); all
other Realtime paths are proven end-to-end.
Tests
- realtime-postgres-changes.test.ts: now uses afterEach socket disconnect
(Vitest singleFork kept Phoenix sockets alive between files, leaking state)
- realtime-isolation.test.ts (new): R-I-01 David (guest, same collective)
receives events; R-I-02 Eva (non-member) receives NONE — RLS is enforced
server-side per subscribed JWT
- realtime-presence.test.ts (new, describe.skip): two-client roster + leave
assertions ready, gated on upstream bug
- sync-queue.test.ts (new, describe.skip): 7 placeholders pinning the
apps/web/src/lib/sync/queue.ts contract (Q-01..Q-04 enqueue / in-order
flush / retry; F-01..F-03 online-event flush + last-write-wins)
- apps/web/tests/e2e/{session,realtime,offline}.test.ts (new, describe.skip):
S-01..S-03, R-E-01, R-E-02, O-01, O-02 pinning the Modo Compra UI contract
- vitest.config.ts: fileParallelism=false, drop singleFork so each file gets
a fresh worker fork — prevents RealtimeClient singleton leakage
Infra
- db-init/00-role-passwords.sh: pre-create `realtime` schema with
AUTHORIZATION supabase_admin. Realtime's per-tenant migrator creates tables
INSIDE the schema but does not create the schema itself; without this the
first tenant connect fails with "schema realtime does not exist"
- docker-compose.dev.yml: adopt the upstream supabase/supabase Realtime env
shape — SEED_SELF_HOST=true + RUN_JANITOR=true + RLIMIT_NOFILE=10000 +
drop the custom `command: eval seeds` (that bypasses the normal supervisor
startup and was observed to cause GenServer crashes under load).
Version pinned to v2.76.5 to match the official docker-compose.
Known upstream bug
- Realtime v2.76.5 and v2.83.0 both crash on presence_diff:
`(UndefinedFunctionError) RealtimeChannel.handle_out/3 is undefined`.
postgres_changes + isolation unaffected (they don't traverse handle_out).
Presence tests stay `describe.skip` until a fixed upstream is released.
Totals: 59 Vitest passed (+ 9 skipped awaiting implementation/upstream),
16 pgTAP, 15 Playwright (+ 7 E2E scaffolded for 2b UI) = 90 green.
