## Known Gaps / Not Yet Implemented

### In Phase 1 (minor gaps)

| Item | Priority | Notes |
|------|----------|-------|
| `store.save_analysis()` is a no-op | Medium | Method exists but doesn't persist analysis results to SQLite |
| Supabase credentials are placeholders | Medium | URL and anon key need real values; env var overrides work |
| `hints.yaml` not created | Low | Hints are in Python code directly — works fine, YAML was optional |
| No `.gitignore` | Low | Should add to exclude __pycache__, .db files, etc. |
| No `README.md` | Low | Plan puts this in Phase 4 |
| No git commits | Low | Project is unversioned |

### Phase 2: Remaining Rigol Devices — NOT STARTED

| Device | Module Path | USB Product ID |
|--------|-------------|----------------|
| Rigol DP832 (power supply) | `hardware_agent/devices/rigol_dp832/module.py` | TBD from lsusb |
| Rigol DL3021 (electronic load) | `hardware_agent/devices/rigol_dl3021/module.py` | TBD from lsusb |
| Rigol M300 (DAQ/switching) | `hardware_agent/devices/rigol_m300/module.py` | TBD from lsusb |

Each is ~60-80 lines + test file. Architecture supports this — just set class attributes and override hooks.

### Phase 3: Non-Rigol Devices — NOT STARTED

| Device | Module Path | Notes |
|--------|-------------|-------|
| Siglent SDS1104X-E | `hardware_agent/devices/siglent_sds1104xe/module.py` | New vendor, tests cross-manufacturer support |
| Keithley 2400 | `hardware_agent/devices/keithley_2400/module.py` | May need GPIB resource string handling in VisaDevice |

### Phase 4: Polish — NOT STARTED

- Real hardware validation against all 4 physical Rigol devices
- Fix product IDs, hints, quirks discovered during testing
- `--verbose` / `--debug` flags
- Cost/token tracking display
- API key validation improvements
- Network error handling edge cases
- `README.md`
