## Success Criteria Verification

| Criterion | Status |
|-----------|--------|
| `docs/ux-contract.md` defines step sequences for install, sync, OCR, dashboard | PASS |
| Each step has single measurable outcome + error contract | PASS |
| `test_new_user_onboarding` completes full workflow | PASS |
| `test_existing_user_adds_paper` completes full workflow | PASS |
| All journey tests use `journey_vault` fixtures with isolation guards | PASS |
| `CHAOS_MATRIX.md` documents 15+ destructive scenarios | PASS |
| Corrupted input tests produce graceful error messages | PASS |
| Network failure tests produce actionable error messages | PASS |
| All chaos tests include `assert "tmp"/"temp" in str(vault)` | PASS |
| `ci-chaos.yml` with weekly schedule + manual trigger | PASS |
| `ci.yml` NOT modified — chaos excluded from PR gate | PASS |
| All journey/chaos tests marked with appropriate pytest markers | PASS |

## Isolation Guard Coverage

All 16 fixture definitions and inline assertions verified:
- `tests/journey/conftest.py`: journey_fresh_vault, journey_established_vault
- `tests/journey/test_onboarding.py`: inline guard
- `tests/journey/test_daily_workflow.py`: inline guard
- `tests/chaos/conftest.py`: chaos_vault, chaos_vault_standard
- `tests/chaos/test_corrupted_inputs.py`: 6 inline guards
- `tests/chaos/test_network_failures.py`: 4 inline guards
- `tests/chaos/test_filesystem_errors.py`: 4 inline guards

## Deferred Issues

1. **Malformed JSON causes traceback** (`test_malformed_bbt_json`): The `load_export_rows` function crashes with a full Python traceback when export JSON is truncated. The application logs a `WARNING` before crashing, which is partial grace, but the unhandled `JSONDecodeError` should be caught and converted to a clean error message.
