Max Carlson · claude · Max Carlson · commit 9530c2027b56 · 2025-11-19T19:03:40.000+08:00
This commit includes documentation updates and configuration files from the Phase 4 implementation session: **New Files:** 1. `.env.example` - Environment variable template for Supabase integration - VITE_SUPABASE_URL and VITE_SUPABASE_ANON_KEY examples - Documentation for integration test setup 2. `docs/SUPABASE_REALTIME_TROUBLESHOOTING.md` - Debugging guide - Common Realtime connection issues and solutions - Channel subscription patterns - Connection state debugging 3. `docs/plans/2025-01-19-phase-3-declarative-api.md` - Phase 3 plan - Declarative API implementation details - SceneGraph, DataPipeline, Layout system design 4. `docs/plans/2025-11-19-phase-4-physics-magnets.md` - Phase 4 plan - Rapier physics engine integration - Magnet system with metadata filtering - 10 tasks with detailed implementation steps 5. `docs/gpgpu-physics-research-2025.md` - GPGPU research notes - GPU-accelerated physics options - WebGPU Compute Shaders vs WebAssembly comparison **Modified Files:** 1. `.gitignore` - Added manual test files and temp directories 2. `docs/supabase-setup.md` - Updated integration test instructions 3. `src/physics/PhysicsWorld.ts` - Minor formatting/comment updates from Phase 4 implementation 4. `src/transports/SupabaseTransport*.ts` - Transport implementation refinements and test updates 5. `docs/plans/2025-01-18-threejs-viewer-design.md` - Updated to reflect Phase 3 and Phase 4 completion 6. `.claude/settings.local.json` - Claude Code session settings **What This Represents:** This commit captures the documentation and configuration state after completing Phase 4 (Rapier physics + magnet system). All implementation files were committed in separate atomic commits during the Phase 4 work. This commit ensures: - Contributors can set up Supabase for integration tests - Troubleshooting documentation available for Realtime issues - Phase 3 and Phase 4 plans documented for future reference - GPGPU research notes preserved for future physics optimization 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

+# Supabase Realtime Troubleshooting Report
+
+**Date**: November 19, 2025
+**Project**: gwodhwyvuftyrvbymmvc.supabase.co
+**Issue**: Integration tests failing with connection timeouts
+
+## Summary
+
+Integration tests for `SupabaseTransport` are failing because the Supabase Realtime WebSocket connection returns **HTTP 403 Forbidden**. The REST API works correctly, confirming the project is active and credentials are valid.
+
+## Diagnostic Results
+
+### ✅ Working
+- REST API endpoint: `https://gwodhwyvuftyrvbymmvc.supabase.co/rest/v1/` returns 200
+- Project is active (not paused)
+- Credentials are valid
+- Supabase client library loads correctly (@supabase/supabase-js@2.83.0)
+
+### ❌ Not Working
+- Realtime WebSocket endpoint: `wss://gwodhwyvuftyrvbymmvc.supabase.co/realtime/v1/websocket` returns 403
+- Channel subscription never completes (no callback fired)
+- `subscribe()` callback receives no status updates (not even TIMED_OUT)
+
+## Configuration Checked
+
+1. **Dashboard Settings**:
+   - Realtime feature: Enabled
+   - "Allow public access": Enabled
+   - Feature was disabled and re-enabled (no effect)
+
+2. **Database**:
+   - `realtime.messages` table: **Does not exist**
+   - Note: This table is only needed for database-triggered broadcasts, not client-to-client
+
+3. **Client Configuration**:
+   - Using broadcast with `{ self: true, ack: false }`
+   - No private channel settings
+   - No authentication required
+
+## Root Cause Analysis
+
+The 403 error from the Realtime endpoint suggests:
+
+1. **Service Not Fully Initialized**: After enabling/disabling Realtime, the service may need 5-10 minutes to fully start
+2. **Plan/Billing Restriction**: Free tier or billing issue preventing Realtime access
+3. **Missing Internal Configuration**: Dashboard shows "enabled" but internal routing/permissions aren't set up
+4. **Regional/Network Issue**: Less likely since REST API works
+
+## Test Commands Used
+
+```bash
+# Test REST API (works)
+curl -I https://gwodhwyvuftyrvbymmvc.supabase.co/rest/v1/
+
+# Test Realtime endpoint (403)
+curl -I https://gwodhwyvuftyrvbymmvc.supabase.co/realtime/v1/websocket \
+  -H "apikey: <anon-key>"
+
+# JavaScript connection test
+node test-supabase.js           # Times out
+node test-broadcast-simple.js   # No callback
+```
+
+## Recommended Actions
+
+### For User
+1. Check **Settings → Billing** for any warnings or service restrictions
+2. Verify project plan includes Realtime (check quotas)
+3. Wait 10-15 minutes after toggling Realtime, then retry
+4. Try **Database → Realtime Inspector** in dashboard to test broadcast
+5. Consider creating a fresh Supabase project to verify Realtime works there
+
+### For Development
+1. Use mock transport for unit tests (don't require real Supabase)
+2. Make integration tests optional via environment variables
+3. Add clear skip messages when Supabase not configured
+4. Document Realtime setup requirements in README
+
+## Workaround Implemented
+
+Integration tests now:
+- Check for `VITE_SUPABASE_URL` and `VITE_SUPABASE_ANON_KEY` environment variables
+- Skip with clear message if not configured
+- Use mock transport for unit tests (always run)
+- Can be run with real Supabase when credentials are in `.env`

+Unit tests use `MockTransport` and don't require Supabase:

+### Integration Tests (Optional)
 
-```bash
-npm test -- --run SupabaseTransport.integration
-```
+Integration tests require a real Supabase instance with Realtime enabled. **They are automatically skipped** if credentials are not configured.
+
+**To enable integration tests:**
+
+1. Copy `.env.example` to `.env`:
+   ```bash
+   cp .env.example .env
+   ```
+
+2. Edit `.env` and add your credentials:
+   ```
+   VITE_SUPABASE_URL=https://gwodhwyvuftyrvbymmvc.supabase.co
+   VITE_SUPABASE_ANON_KEY=your-anon-key-here
+   ```
+
+3. Run integration tests:
+   ```bash
+   npm test -- SupabaseTransport.integration
+   ```
 
 **Note**: Integration tests may fail if:
-- Realtime broadcast is not enabled
-- Network connectivity issues
-- Supabase project is not properly configured
+- Realtime is not enabled (see Setup Steps above)
+- Realtime service is still initializing (wait 5-10 minutes after enabling)
+- Network/firewall blocking WebSocket connections
+- Project has billing/quota issues
+
+If integration tests fail, see `docs/SUPABASE_REALTIME_TROUBLESHOOTING.md`
