 3. **Orchestration & Playtesting (`/home/daddy/agp`)**:
    - PM Dashboard: `http://localhost:7070` (`agp-dashboard.service`).
-   - Checkpoint system: `pm/checkpoint_ops.py` controls playtest instances (`PC1` through `PC4`).
-   - Current active checkpoint: **PC4** (backend on `http://192.168.58.138:28004`, postgres on `25544`).
-   - Building Windows package: `PYTHONPATH=. /home/daddy/agp/venv/bin/python3 -c "import pm.checkpoint_ops as ops; ops.build_exe('PC4')"`

 4. **Testing Protocols**:
-   - Headless smoke tests: `AGP_API_BASE_URL=http://127.0.0.1:28004 ~/godot/godot --headless --path . --script res://scripts/smoke_test_<name>.gd`
+   - Headless smoke tests: `AGP_API_BASE_URL=http://127.0.0.1:28005 ~/godot/godot --headless --path . --script res://scripts/smoke_test_<name>.gd`
+   - Fast checkpoint tests: `PYTHONPATH=. /home/daddy/agp/venv/bin/python3 scripts/run_checkpoint_tests.py --skip-backend --filter <keyword>`
    - Backend pytest: `PYTHONPATH=. /home/daddy/agp/venv/bin/pytest backend/tests`
