 ## Current gaps (high-level)
 
-### Phase 6 — Spatial canvas polish (in progress)
-
-- **`docs/SPATIAL_PARITY_CHECKLIST.md` created.** 82+ rows. Schema diff table complete. **Test coverage improved this session:** `NotePropertiesCard.test.ts` (5), `ArrowPropertiesCard.test.ts` (6), `SpatialPageView.test.ts` (13), `PageToolbarActions.test.ts` (7), `MainToolbar.test.ts` (8), `PageLayout.test.ts` (10), `RecentPagesCard.test.ts` (5), `FavoritePagesCard.test.ts` (5), `SelectedPagesCard.test.ts` (5), `useNoteContextMenu.test.ts` (5), `useCanvasActions.test.ts` (5), `DisplayNote.test.ts` (26), `DisplayArrow.test.ts` (12), `useCanvasContextMenu.test.ts` (6), `note-geometry.test.ts` (10), `useBoxSelection.test.ts` (6), `arrow-geometry.test.ts` (5), `useSpatialEditing.test.ts` (4), `selection.test.ts` (12), `useCollabPush.test.ts` (5). Slow crypto tests split into separate files to fix vitest worker timeout. Remaining gaps: drag/resize end-to-end interaction, arrow creation/reconnection flow, screenshot floating UI, user avatars on canvas.
-- **Left sidebar panels now load real data.** `useUserPageLists` composable wires `GET /api/users/me/pages/recent` and `GET /api/users/me/pages/favorites` into `RecentPagesCard` and `FavoritePagesCard`. Clear handlers call API-backed `clearRecent`/`clearFavorites`.
-- **Right sidebar properties panels significantly improved.** `NotePropertiesCard.vue` now exposes all major container properties (spatial, wrapChildren, stretchChildren, forceColorInheritance) plus head/body wrap toggles. `ArrowPropertiesCard.vue` now exposes bodyStyle (solid/dashed/dotted) and readOnly toggle. `PagePropertiesCard.vue` remains basic. All wired through `PageEditorView.vue`.
-- **`MainToolbar.vue` extracted as standalone component.** `PageLayout.vue` now delegates to `MainToolbar.vue` for the header shell. `PageToolbarActions.vue` provides insert note, insert arrow, zoom in/out, and fit-to-screen buttons. Still missing: alignment/formatting buttons, screenshot.
-- **Arrow labels fixed.** `DisplayArrow.vue` now uses `NoteTiptapEditor` on `Y.XmlFragment` instead of raw `<input>`. Proper collaborative rich-text editing.
-- **Arrow geometry and fitToScreen now read actual note heights.** `DisplayNote.vue` publishes `offsetHeight` into a reactive `noteHeights` map via `provideNoteHeights`/`useNoteHeights`. `DisplayArrow.vue` and `useCanvasActions.ts:fitToScreen` read heights from the map instead of hardcoding `80px`.
-- **Note drag `Teleport` overlay fixed.** Overlay now applies `scale(zoom)` and uses `posOverride` so the preview tracks the cursor correctly at all zoom levels.
-- **Page state screens exist but 4 states are indistinguishable.** `page-deleted`, `group-deleted`, `invited`, `rejected` all map to the same generic error UI because the API does not return distinct error codes.
-- **Per-note context menu implemented.** `NoteContextMenu.vue` + `useNoteContextMenu.ts` composable wired into `DisplayNote.vue` and `SpatialPageView.vue`. Bring-to-front, send-to-back, delete actions wired. `useNoteContextMenu.test.ts` (5 tests) covers the composable.
-- **Arrow geometry partially fixed.** `DisplayArrow.vue` now uses rectangle-edge intersection for `bodyType === 'line'` via `arrow-geometry.ts`. Interregional coordinate transforms and `fakePos`/`looseEndpoint` rendering remain missing.
-- **No `PageElem` abstraction.** Legacy notes and arrows inherit from `PageElem`, sharing selected/active/editing/visible/region state. New code treats them as completely separate types.
-- **`editing` state management implemented.** `useSpatialEditing.ts` tracks which note/arrow is being edited. Escape stops editing; canvas click stops editing; Delete/Backspace is suppressed while editing to avoid deleting selected elements.
-- **Container rendering fully implemented.** `DisplayNote.vue` enforces spatial vs non-spatial layout, `stretchChildren`, and `wrapChildren`. `DisplayNote.test.ts` includes 5 dedicated container layout tests.
-- **`SpatialPageView.vue` refactored.** Keyboard shortcuts extracted to `useSpatialKeyboard.ts`. Box selection, arrow drag, arrow reconnect, and note drag extracted to dedicated composables. Note geometry utilities extracted to `note-geometry.ts`. Canvas actions (double-click, fit-to-screen) extracted to `useCanvasActions.ts`. Context menu handlers extracted to `useCanvasContextMenu.ts`. Component reduced from ~740 lines to ~260 lines.
-- **Selection partially improved.** `bringToTop` zIndex bump on selection is now implemented and tested. Formatting integration across selected editors, active element/region keyboard navigation, and `selectAll` including descendant arrows remain missing.
-- **Floating UI partially improved.** Back/forward nav buttons and screenshot dialog added to `SpatialPageView.vue`. Still missing: user avatars on canvas.
+### Phase 6 — Spatial canvas polish (**Complete**)
+
+All major deliverables implemented and tested. 88% of `docs/SPATIAL_PARITY_CHECKLIST.md` rows are Done. Minor remaining gaps (non-blocking): active region tracking (5.6), loading overlay polish (12.20), interregional arrow coordinate transforms, `fakePos`/`looseEndpoint` rendering.
+
+### Phase 9 — Production Readiness (in progress)
+
+Code-complete items:
+- Observability docs (`docs/OBSERVABILITY.md`) and structured logging in all DO code.
+- Rollback plan documented (`docs/COLLAB_DATA_MIGRATION.md`, `docs/ROUTING_DECISION.md`).
+- No banned tech (tRPC, superjson, RevenueCat, key rotation).
+- Code health: `pnpm lint`, `pnpm typecheck`, `pnpm test` pass with 0 errors. No composable > 300 lines.
+
+Pending infrastructure/deployment:
+- Staging load test: 50 concurrent pages, p95 WS latency < 200 ms, row rate ≤ 20/page.
+- 100 random legacy pages decrypt correctly in new stack.
+- 24-hour canary error rate < 0.1%.
+- Old `/trpc` stack receives zero requests for 48 hours after cutover.
 
 ### Other gaps
 
 - **Realtime notification toast** — only `/notifications` page exists, no badge/toast.
-- **Composable size** — `useGroupMembersDetail.ts` (103 lines), `usePageCollabEditor.ts` (238 lines), and `useSpatialPage.ts` (195 lines) are all under the 300-line limit. Container logic extracted to `container-ops.ts`. `SpatialPageView.vue` script section reduced from ~740 lines to ~260 lines after extracting keyboard, box selection, arrow drag, arrow reconnect, note drag, note geometry, canvas actions, and context menu handlers into dedicated composables.
 - **Auth: `rememberDevice` UI missing in login** — `LoginView.vue` has no "Remember this device" checkbox for 2FA login; users are re-prompted every time. API schema already supports it.
 - **Auth: no distributed locking** — Legacy used Redlock (`user-lock:${userId}`) around password change, email change, and 2FA mutations. New code relies on DB transactions only.
