docs(fase-5): close-out — plan, CLAUDE.md, README status

Fase 5 is ✅ complete in automatable scope after the last five feature
commits (d6cea51, 4cc5f69, d14d6cd, 1cb408a, f3e8234). 228 tests green,
4 skipped. Deferred: WebKit-dependent swipe/long-press E2E, card
presence avatars, max-w-2xl reading width.

-### Fase 5 — what has been built (partial)
+### Fase 5 — what has been built (complete in scope)
+
+**5.8 big-button create (match /notes)**
+- `/lists` sticky bottom create bar removed; masthead gains a primary "New list" button next to the Trash ghost icon
+- `handleCreate` creates with empty name + `goto(/lists/[id])`; detail view shows a prominent editable title input (26–32px) with 500 ms autosave (`renameList`)
+- Matches `/notes` pattern end-to-end
+
+**5.10 row redesign (button-row + gesture toggle + overlay + drag handles)**
+- Shopping items have **no checkbox** in normal mode. Row is `drag-handle | name-button | qty stepper`. Checked items render strikethrough + muted.
+- **Swipe right on unchecked → mark checked** (green reveal), **swipe left on checked → uncheck** (neutral reveal). Opposite direction is a no-op snap-back. `SWIPE_COMMIT_THRESHOLD=120`, `SWIPE_REVEAL_WIDTH=96`. No undo toast — the gesture is symmetric and the inverse swipe reverses.
+- **Double-tap opens an overlay** (Dialog / bottom sheet) with: name input + Delete (red) + Confirm + X close. 300 ms tap-window. Delete still routes through `scheduleUndoable` → `UndoToast`.
+- **Drag handle** on the left, always visible on mobile, `md:opacity-0 md:group-hover:opacity-100` on desktop. Handle's `onpointerdown` flips a `dragEnabled` flag so dnd only kicks in from the handle, leaving row swipes untouched.
+- `unit` column **dropped** (migration `011_drop_shopping_items_unit.sql`). The double-tap overlay only edits name, so an unreachable `unit` would be stranded data. Users encode units inside the name (e.g. "Milk 1L"); seed updated accordingly.
+
+**5.11 selection mode + bulk actions**
+- **Entry**: long-press 500 ms on mobile or `data-testid="selection-toggle"` button in the desktop header. Preselects the row you pressed (mobile).
+- Inside selection mode: single-tap toggles selection, swipe + double-tap disabled, stepper + drag handle hidden. Row gains a checkbox on the left.
+- **Chrome**: header turns into `data-testid="selection-bar"` (dark slate-900 with "N selected" + Cancel + desktop-inline actions). Mobile bottom action bar (`data-testid="selection-action-bar"`) above BottomTabBar with Delete / Move / Mark-checked.
+- **Bulk actions** (one Supabase call each): `bulkDeleteItems` + single UndoToast with batch snapshot, `bulkMoveItems` via a list picker sheet (`data-testid="move-picker"`) listing the collective's other active lists + a "Create new list" row, `bulkCheckItems` filters `is_checked=false` so it only marks, never toggles.
+
+**5.12 detail-view chrome (hide MobileTopBar, sticky contextual bars)**
+- On `/lists/[id]`, `/tasks/[id]`, `/notes/[id]`, `/lists/[id]/session` the global `MobileTopBar` is hidden via an `isDetailRoute` regex check in `(app)/+layout.svelte`. The route's own contextual header (back + title + actions) becomes the only top chrome and is now `sticky top-0 z-30 bg-surface/80 backdrop-blur-xl`.
+- `BottomTabBar` stays visible so users can hop between sections.

+### Fase 5 — earlier sub-phases (still relevant)
 
 - `apps/web/src/lib/components/layout/DesktopSidebar.svelte` — desktop sidebar extracted from `(app)/+layout.svelte`, `data-testid="desktop-sidebar"`, `hidden md:flex`
 - `apps/web/src/lib/components/layout/MobileTopBar.svelte` — hamburger + collective name + avatar link; `md:hidden sticky top-0 z-30 backdrop-blur-xl`
