## Track

## Verification Results

### Tests directly verified to pass post-fix

| Test File | Tests | Result | Notes |
|-----------|-------|--------|-------|
| `tests/test_mma_tier_usage_reset_fix.py` | 4 | 4/4 PASS | NEW regression tests (FR1-FR4) |
| `tests/test_reset_session_clears_mma_and_rag.py` | 3 | 3/3 PASS | Pre-existing fe240db4 regression tests |
| `tests/test_context_presets_manager.py` | 4 | 4/4 PASS | Includes test_app_controller_save_load (was failing pre-FR3) |
| `tests/test_project_switch_persona_preset.py` | 9 | 9/9 PASS | Includes test_load_active_project_creates_persona_manager and test_load_context_preset_missing_raises_keyerror (both failing pre-track) |
| `tests/test_handle_reset_session_clears_project.py` | 4 | 4/4 PASS | _handle_reset_session related |
| `tests/test_view_presets.py` | 5 | 5/5 PASS | Calls _flush_to_project at line 54 |
| `tests/test_tiered_aggregation.py` | 3 | 3/3 PASS | mma_tier_usage related |
| `tests/test_extended_sims.py` (live_gui) | 4 | 4/4 PASS | test_context_sim_live + 3 siblings; the original failure that motivated the track |

**Total: 36/36 directly-affected tests pass**

### What was failing pre-track
- `test_context_sim_live` (and 3 sibling sim tests) — `KeyError: 'model'` from `_flush_to_project` because `mma_tier_usage` was reset to empty dicts
- `test_app_controller_save_load` — `AttributeError: 'NoneType' object has no attribute 'save_preset'` (missing `self.context_preset_manager` init)
- `test_load_context_preset_missing_raises_keyerror` — same as above
- `test_load_active_project_creates_persona_manager` — `hasattr()` returned True for missing `persona_manager` because `__getattr__` returned None

### Commits Applied (atomic per-FR)
1. `d80c94b9` FR1: pre-populate `mma_tier_usage` on reset
2. `1919aa8a` FR2: `_flush_to_project` defensive `d.get("model")`
3. `bc4651d1` FR3: re-add `self.context_preset_manager = ContextPresetManager()` in `__init__`
4. `4284ec6e` FR4: remove `persona_manager` from `_LAZY_MANAGER_DEFAULTS` + fix misleading comment
5. `b96d709e` Regression tests

### Note on the test fixture
The test fixture in `tests/test_mma_tier_usage_reset_fix.py` sets 4 UI flags (`ui_project_preset_name`, `ui_word_wrap`, `ui_gemini_cli_path`, `ui_auto_add_history`) that `_flush_to_project` reads but `__init__` does not initialize. This is a test-only setup, not a production change. The pre-existing working tree (from a previous agent's WIP commit) had removed 7 entries from `_UI_FLAG_DEFAULTS` including 3 of these flags. Reverting the `_UI_FLAG_DEFAULTS` refactor was deemed out of scope for this track; the test fixture was extended instead. A follow-up to clean up `_UI_FLAG_DEFAULTS` is recommended.

### Note on full batch run
The full `scripts/run_tests_batched.py` run was aborted by the user after a partial run. The targeted test runs above cover all known affected code paths. The 4 sim tests, which were the primary motivation for the track, all pass.
