- For detecting legacy data shape (pre-migration), pass a flag from the server component (page.tsx) to the client component, since only the server reads raw DB data.
- Collaboration tables: `project_collaborators` (roles), `collaboration_sessions` (presence), `audit_trail` (history) — all with RLS scoped by project ownership or collaborator membership
- RLS pattern for shared resources: check `projects.user_id = auth.uid()` OR `project_collaborators.user_id = auth.uid()` to cover both owners and collaborators
- `RealtimeConnection` class at `src/lib/collaboration/realtime.ts` manages Supabase Realtime channel lifecycle (connect, heartbeat, reconnect, disconnect). Instantiate with (projectId, userId, callbacks).
- FlowchartEditor receives `userId` prop from page.tsx server component for collaboration features
- Toolbar accepts optional `connectionState` prop to show green/yellow/red connection indicator
- `collaboration_sessions` table has UNIQUE(project_id, user_id) constraint to support upsert-based session management

- `collaboration_sessions.cursor_position` is JSONB to store flexible coordinate data (x, y, and potentially viewport info)
- `collaboration_sessions.selected_node_id` is nullable text since a user may not have any node selected

## 2026-01-23 - US-045
- What was implemented: Supabase Realtime channel and connection management with connection lifecycle, heartbeat, auto-reconnect, and toolbar status indicator
- Files changed:
- `src/lib/collaboration/realtime.ts` - New module: `RealtimeConnection` class with connect/disconnect, heartbeat (30s interval), exponential backoff reconnect, session upsert/delete, presence sync callback
- `src/components/editor/Toolbar.tsx` - Added `connectionState` optional prop with color-coded indicator (green=connected, yellow=connecting/reconnecting, red=disconnected)
- `src/app/editor/[projectId]/FlowchartEditor.tsx` - Added `userId` prop, imported `RealtimeConnection`, added `connectionState` state + `useEffect` for connection lifecycle, passed `connectionState` to Toolbar
- `src/app/editor/[projectId]/page.tsx` - Passed `userId={user.id}` to FlowchartEditor component
- `supabase/migrations/20260123200000_add_collaboration_sessions_unique_constraint.sql` - Added UNIQUE(project_id, user_id) constraint for upsert support
- **Learnings for future iterations:**
- Supabase Realtime channel subscription statuses are: `SUBSCRIBED`, `CHANNEL_ERROR`, `TIMED_OUT`, `CLOSED`. Handle each for connection state tracking.
- The `RealtimeConnection` class creates its own Supabase client instance via `createClient()` since the browser client is stateless and cheap to create
- `useRef` is used to hold the connection instance across renders without triggering re-renders. The `useEffect` cleanup calls `disconnect()` to properly clean up.
- The Supabase channel name is `project:{projectId}` — future stories (presence, CRDT) should join the same channel via `realtimeRef.current.getChannel()`
- The `collaboration_sessions` table needed a UNIQUE constraint on (project_id, user_id) for the upsert pattern to work; this was added as a separate migration
- Pre-existing lint errors in ConditionEditor.tsx and OptionConditionEditor.tsx (React Compiler `preserve-manual-memoization`) are unrelated to this story
- No browser testing tools are available; manual verification is needed.
