# Phase 2: Code Review Report -- Task 1 OCR Structured Pipeline

**Reviewed:** 2026-06-04T15:30:00Z
**Depth:** standard
**Files Reviewed:** 2
**Status:** issues_found

## Summary

This task creates three TDD contract tests across two files that lock the Phase 1 OCR artifact contract (directory layout, version payload schema, postprocess artifact emission) in a failing state, exactly as specified in the plan. The tests will be made to pass by subsequent tasks.

The implementation is correct in intent and faithfully follows the plan. However, one code quality defect was found: a missing `Path` import in `tests/test_ocr.py` that creates a fragility when the annotation is evaluated on Python < 3.14 and violates the project's established convention (every other test file imports `Path`).

All 3 new tests fail as expected in the current environment:
- 2 fail with `ModuleNotFoundError` (target module does not exist yet) -- correct
- 1 fails with `AssertionError` (artifact files not written yet) -- correct

All 4 pre-existing tests in `tests/test_ocr.py` continue to pass -- no regression detected.

### Test Failure Diagnostics

| Test | Failure Type | Expected? |
|------|-------------|-----------|
| `test_phase1_artifact_layout_is_paper_local` | `ModuleNotFoundError: No module named 'paperforge.worker.ocr_artifacts'` | YES -- TDD contract, module not yet created |
| `test_raw_and_derived_version_payloads_have_separate_namespaces` | `ModuleNotFoundError: No module named 'paperforge.worker.ocr_artifacts'` | YES -- TDD contract, module not yet created |
| `test_postprocess_writes_phase1_artifacts` | `AssertionError: assert False` at line 169 | YES -- `postprocess_ocr_result()` does not yet write Phase 1 artifacts |

## Warnings

### WR-01: Missing `Path` import in `test_ocr.py` creates annotation fragility

**File:** `tests/test_ocr.py:154`
**Issue:** The function signature `def test_postprocess_writes_phase1_artifacts(tmp_path: Path) -> None:` references `Path` in a type annotation, but `Path` is not imported in `tests/test_ocr.py`. This file has zero module-level imports -- the only test file in the project with this characteristic. Every other test file consistently uses `from pathlib import Path`.

This works in Python 3.14 due to PEP 649 (deferred annotation evaluation), but it:
- **Fails with `NameError` on Python < 3.14** if the module is imported without `from __future__ import annotations`
- Creates a hidden dependency on the conftest's import order and PEP 649 being active
- Violates the project's established convention (all other test files with `Path` annotations import it explicitly)

**Fix:** Add `from pathlib import Path` to `tests/test_ocr.py` at module level. This is consistent with the pattern used in `tests/test_ocr_redo.py`, `tests/test_ocr_artifacts.py`, `tests/test_context.py`, and every other test file in the project.

```python
# Add to tests/test_ocr.py, before the first test function:
from pathlib import Path
```

Alternatively, if the project intentionally uses annotation-only mode for all test files, add `from __future__ import annotations` at the top of `tests/test_ocr.py` (matching `tests/test_ocr_artifacts.py` and `tests/conftest.py`).

## Assessment

### Strengths

1. **Plan alignment:** The implementation matches the plan exactly -- both `test_ocr_artifacts.py` tests and the `test_ocr.py` addition are verbatim from the spec.

2. **Design alignment:** The contract tests correctly reflect the design spec (`docs/superpowers/specs/2026-06-04-ocr-structured-pipeline-design.md`):
   - `raw/raw_meta.json` and `raw/source_metadata.json` match Layer 0/1 artifacts
   - `canonical/blocks.raw.jsonl` matches Layer 2
   - `structure/blocks.structured.jsonl` matches Layer 3
   - `raw_version`/`derived_version` payloads match Section 6 version model

3. **Well-scoped scope:** The task did not leak into implementation work -- no production source files were modified, no `ocr_artifacts.py` was prematurely stubbed.

4. **Explicit path assertions:** Using `.as_posix().endswith(...)` in `test_ocr_artifacts.py` correctly handles Windows vs POSIX path separators, making the tests cross-platform.

5. **Clean new file:** `tests/test_ocr_artifacts.py` is small (29 lines), has a single responsibility (contract tests), and is independently importable.

### Defects

| ID | Severity | Description | File:Line |
|----|----------|-------------|-----------|
| WR-01 | Warning | Missing `Path` import in `test_ocr.py` | `tests/test_ocr.py:154` |

### Verification

- Module-level imports absent from `tests/test_ocr.py`: confirmed by `rg` (zero results)
- All other 21 test files import `Path` from `pathlib`: confirmed by `Select-String` across `tests/*.py`
- All 3 new tests fail as expected: confirmed by running `pytest` against both files
- All 4 pre-existing tests still pass: confirmed by `pytest` output
- Design spec alignment: confirmed by reading the design doc
