Track all training data sync operations with detailed metrics:
- Add vision_training_sync_history table with SQLite schema
- Record sync start/end times, file counts, tombstone stats
- Prune tombstone entries for files that no longer exist on remote
- Show sync history indicator in ColumnClassifierDataPanel
New files:
- vision-training-sync-history.ts - DB schema for sync history
- sync/history/route.ts - API to query sync history
- SyncHistoryIndicator.tsx - UI component showing recent syncs
The tombstone pruning ensures local tombstone files don't grow unbounded -
after each sync, entries for files deleted on remote are removed since
there's no longer a risk of re-syncing them.

Next.js App Router caches GET route handlers by default when they
don't use request-based data. This caused /api/vision-training/samples
to return cached "no data" responses even after data was collected.
Added `export const dynamic = 'force-dynamic'` to all vision-training
API routes that read from disk or run system commands:
- samples/route.ts
- hardware/route.ts
- preflight/route.ts
- sync/route.ts
- train/route.ts

Research confirmed TensorFlow has wheels for Linux x86_64 (including
Synology NAS). The previous failures were due to:
1. Training scripts not being copied to Docker image
2. Venv path not being writable in container
Changes:
- Update isPlatformSupported() to include Linux ARM64 support
- Move venv to data/vision-training/.venv (mounted volume, writable)
- Add python3-venv to Docker image dependencies
- Copy training scripts to Docker image
- Create vision-training directories in Docker build
Sources:
- https://www.tensorflow.org/install/pip
- https://pypi.org/project/tensorflow/ (shows manylinux_2_17_aarch64 wheels)

The vision training APIs now automatically set up the Python
environment when first called:
1. Detects if venv exists with tensorflow installed
2. If not, finds best Python (ARM on Apple Silicon for Metal GPU)
3. Creates venv and installs tensorflow (with Metal on M-series Macs)
4. Caches result so subsequent calls are instant
This eliminates the need to manually set up the venv before deployment.
The setup happens lazily on first hardware detection or training request.
Also includes various other working tree changes that were in progress.

- Fix hook dependency issues in AbacusVisionBridge by using destructured

- Add proper container dimension tracking for remote camera calibration
overlay to fix coordinate mismatch
- Add rotate180 option to perspectiveTransform to support both Desk View
(camera pointing down, needs 180° rotation) and phone cameras (no rotation)
- Phone camera cropping now uses direct mapping without rotation
The main issues fixed:
1. Hook dependencies were causing effects to run repeatedly when navigating
to remote camera URL in a different window
2. CalibrationOverlay was using hardcoded fallback dimensions instead of
actual container dimensions for remote camera
3. Perspective transform was applying 180° rotation which is wrong for
phone cameras held at normal angles

**Problem:**
- player-ownership.ts imported drizzle-orm and @/db at top level
- When RoomMemoryPairsProvider imported client-safe utilities, Webpack bundled ALL imports including database code
- This caused hydration error: "The 'original' argument must be of type Function"
- Node.js util.promisify was being called in browser context
**Solution:**
1. Created player-ownership.client.ts with ONLY client-safe utilities
- No database imports
- Safe to import from 'use client' components
- Contains: buildPlayerOwnershipFromRoomData(), buildPlayerMetadata(), helper functions
2. Updated player-ownership.ts to re-export client utilities and add server-only functions
- Re-exports everything from .client.ts
- Adds buildPlayerOwnershipMap() (async, database-backed)
- Safe to import from server components/API routes
3. Updated RoomMemoryPairsProvider to import from .client.ts
**Result:**
- No more hydration errors on /arcade/room
- Client bundle doesn't include database code
- Server code can still use both client and server utilities

Implement hybrid database + application-level enforcement to ensure users
can only be in one room at a time, with graceful auto-leave behavior and
clear error messaging.
## Changes
### Database Layer
- Add unique index on `room_members.user_id` to enforce one room per user
- Migration includes cleanup of any existing duplicate memberships
- Constraint provides safety net if application logic fails
### Application Layer
- Auto-leave logic: when joining a room, automatically remove user from
all other rooms first
- Return `AutoLeaveResult` with metadata about rooms that were left
- Idempotent rejoining: rejoining the same room just updates status
### API Layer
- Join route returns auto-leave information in response
- Catches and handles constraint violations with 409 Conflict
- User-friendly error messages when conflicts occur
### Frontend
- Room list and detail pages handle ROOM_MEMBERSHIP_CONFLICT errors
- Show alerts when user needs to leave current room
- Refresh room list after conflicts to show current state
### Testing
- 7 integration tests for modal room behavior
- Tests cover: first join, auto-leave, rejoining, multi-user scenarios,
constraint enforcement, and metadata accuracy
- Updated existing unit tests for new return signature
## Technical Details
- `addRoomMember()` now returns `{ member, autoLeaveResult? }`
- Auto-leave happens before new room join, preventing race conditions
- Database unique constraint as ultimate safety net
- Socket events remain status-only (joining goes through API)
## Testing
- ✅ All modal room tests pass (7/7)
- ✅ All room API e2e tests pass (12/12)
- ✅ Format and lint checks pass

- Changed CreateSessionOptions.activePlayers from number[] to string[]
- Updated socket-server.ts fallback from [1] to [data.userId]
- Added debug logging to validateFlipCard to diagnose turn validation issues
This ensures that when a session is created without explicit activePlayers,
it uses the actual UUID of the requesting player instead of the numeric value 1.
Fix bug where new route passengers would appear on train cars before
all cars from the previous route had exited through the tunnel.
The issue occurred because passengers were switched when trainPosition < 0
(locomotive exits), but train cars trail behind by up to 35% (5 cars × 7%
spacing). This caused new passengers to briefly appear on the old cars that
were still fading out (positions 65-97%).
Solution: Calculate the last car's position and only switch passengers when:
1. Train has reset to start position (trainPosition < 0), OR
2. All cars have fully faded out (lastCarPosition >= 97%)
Changes:
- useTrackManagement: Added maxCars and carSpacing parameters
- Updated passenger display logic to check lastCarPosition >= fadeOutEnd
- SteamTrainJourney: Pass maxCars and carSpacing from useTrainTransforms
