# Phase 8.5 Summary

## What Was Built

A fix phase that resolved 27 test failures from Phase 8:

### chmod Removal (3 files)
- `src/unfamiliar/config.py` — Removed `_has_strict_permissions()`, chmod on config file creation
- `src/unfamiliar/db/connection.py` — Removed chmod on database file
- `src/unfamiliar/db/__init__.py` — Removed chmod on .repo_path marker

### API Key Simplification
- `resolve_api_key()` now uses environment variables only
- Removed config file `[api_keys]` section support
- Updated error message to not mention config file

### Test Fixes
- `tests/test_config.py` — Removed 6 chmod-related tests, added 1 new test for ignored api_keys
- `tests/test_mission_generator.py` — Converted 19 tests from `mock_chat_model` to `mock_mission_chain`
- `tests/test_conftest_helpers.py` — Removed 4 dead helper tests

### Conftest Cleanup
- Removed `mock_chat_model()` helper
- Removed `mock_briefing_chain()` helper
- Updated `sample_config()` to have empty `api_keys`

## Test Results

- **717 tests passing** (up from 690 with 27 failures)
- **0 failures**
- All property-based tests stable after clearing Hypothesis cache

## Files Modified

| File | Change |
|------|--------|
| `src/unfamiliar/config.py` | Removed chmod, api_keys loading, _has_strict_permissions |
| `src/unfamiliar/db/connection.py` | Removed chmod block |
| `src/unfamiliar/db/__init__.py` | Removed chmod on marker |
| `tests/test_config.py` | Removed chmod tests, updated API key tests |
| `tests/test_mission_generator.py` | Fixed mock setup |
| `tests/test_conftest_helpers.py` | Removed dead helper tests |
| `tests/conftest.py` | Removed mock_chat_model, mock_briefing_chain |

## Security Impact

- **No more file-based secrets** — API keys must come from environment variables
- **No chmod needed** — App no longer requires permission modification
- **Cleaner attack surface** — Config files can't accidentally leak keys

## Next Steps

Phase 9: Campaign orchestration and CLI commands
