## 2) Verification Checklist

- [x] Functional correctness checks completed
- [x] Security checks completed (medium-risk quick checklist)
- [x] Spec compliance checks completed
- [x] Evidence captured

---

## 3) Functional Checks

### 3.1 Implementation Step Completion

- Section 7 statuses in `F006-IMPLEMENTATION_SPEC.md` reviewed.
- Steps 1.1, 1.2, 2.1, 2.2, 2.3, 3.1 are all marked **OK Completed**.
- Section 1a shows **Progress 6/6**, current step none, blockers none.

### 3.2 Test Execution

Evidence:

```bash
uv run --with pytest pytest tests/unit/test_grpo_config.py tests/unit/test_prompts.py tests/unit/test_rollout.py tests/unit/test_rewards.py tests/unit/test_error_handling.py tests/integration/test_training_pipeline.py tests/e2e/test_training_e2e.py -v
```

Result:
- **68 passed in 5.34s**

### 3.3 Training Dependency Import Check

Evidence:

```bash
uv run --extra training python -c "from trl import GRPOConfig, GRPOTrainer; print('ok')"
```

Result:
- **ok**

---

## 4) Security Checks (Medium Risk)

Quick checklist:
- [x] Input validation present (`training/config.py`, question loading checks)
- [x] API/interface changes reviewed (Python-call interfaces only)
- [x] Data validation appropriate (question file/path/JSON checks)
- [x] Quick secrets scan patterns checked (no hits for AWS/GitHub/OpenAI/private key signatures)

Security outcome: ✅ Clear (no findings)

---

## 5) Spec Compliance

### 5.1 Interface + Manifest Alignment

Confirmed files from change manifest exist:

- `training/__init__.py`
- `training/config.py`
- `training/prompts.py`
- `training/rollout.py`
- `training/rewards.py`
- `training/data_loading.py`
- `training/notebook_pipeline.py`
- `notebooks/train_grpo.ipynb`
- `tests/integration/test_training_pipeline.py`
- `tests/e2e/test_training_e2e.py`
- `tests/unit/test_error_handling.py`

`pyproject.toml` includes training optional deps (`trl`, `accelerate`) and import check passed.

### 5.2 Behavioral Updates

- Parse fallback warning behavior confirmed in `training/rollout.py` and validated by `test_action_parse_fallback_logged`.
- Behavior delta archived to `specs/behavior/training.md`.
- Implementation spec updated with Step 3.1 completion and execution status.

### 5.3 Scope Creep / Missing Implementation

- No missing implementation items found for F006 scope.
- No blocking scope creep found within F006 deliverables.

---

## 6) Evidence

- Branch: `feat/grpo-training-pipeline`
- Test suite command + output: 68/68 passed
- TRL import command + output: ok
- Key file checks performed for manifest compliance

---

## 7) Recommendations

- Keep unrelated in-progress files (if any) out of the F006 PR diff.
- After PR prep, mark implementation plan status flags (`Implementation Complete`, `Verification Passed`) as appropriate if your workflow expects those checkboxes to be final-gated.
