# Phase 10: Manual Ruff Leaf-to-Hub Verification Report

**Phase Goal:** Manually fix all remaining ruff violations that ruff --fix cannot auto-correct: E741 ambiguous names, E402 mid-file imports, B017 blind exceptions, and E501 line-length violations across the full non-cli.py codebase. All 281 tests must continue to pass.
**Verified:** 2026-02-24T07:00:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | No E741 ambiguous-name violations exist in database.py or chunked_processor.py | VERIFIED | `link.model_dump()` at db.py:150, `lnk` at db.py:313, `level_val` at chunked_processor.py:64-69; `ruff check` clean |
| 2 | No E402 import-ordering violations exist in llm/rewriter.py | VERIFIED | `import concurrent.futures` at line 3 of rewriter.py; `ruff check` reports zero E402 |
| 3 | No B017 blind-exception violations exist in tests/store/test_schema.py | VERIFIED | `from pydantic import ValidationError` at line 11; `pytest.raises(ValidationError)` at lines 149 and 154 |
| 4 | All 281 tests still pass after variable renames and import moves | VERIFIED | `uv run pytest` output: `281 passed in 3.38s` |
| 5 | scripts/ violations are eliminated by ruff auto-fix | VERIFIED | `uv run ruff check scripts/` → `All checks passed!` |
| 6 | All E501 violations in classifiers/, analyzers/, utils/, search/, and ingest/ are resolved | VERIFIED | `uv run ruff check src/corpus_analyzer/classifiers/ analyzers/ utils/ search/ ingest/` → `All checks passed!` |
| 7 | All E501 violations in core/database.py, generators/, and all test files are resolved | VERIFIED | `uv run ruff check src/corpus_analyzer/generators/ tests/` → `All checks passed!`; `is not None` ternary at db.py:323 confirmed |
| 8 | Zero ruff violations exist outside cli.py across all src/ and tests/ files | VERIFIED | `uv run ruff check . --output-format=concise` shows 47 errors, all exclusively in `cli.py` (Phase 11 scope) |

**Score:** 8/8 truths verified

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|----------|
| RUFF-03 | 10-02, 10-03 | All E501 line-length violations in leaf modules fixed | SATISFIED | Zero E501 violations in all non-cli.py files; `ruff check . --output-format=concise` shows only cli.py violations |
| RUFF-04 | 10-01 | All B-series violations fixed (B017) | SATISFIED | `pytest.raises(ValidationError)` at test_schema.py lines 149/154; zero B017 anywhere |
| RUFF-05 | 10-01 | All F841/E741 violations fixed (ambiguous names) | SATISFIED | `link`/`lnk`/`level_val`/`line` renames in database.py and chunked_processor.py; zero E741 anywhere |
| RUFF-06 | 10-01 | All E402 import ordering violations in llm/rewriter.py fixed | SATISFIED | `import concurrent.futures` at line 3 of rewriter.py; zero E402 anywhere |

No orphaned requirements: RUFF-03, RUFF-04, RUFF-05, RUFF-06 are all claimed by plans and verified.

RUFF-07 (cli.py E501) correctly remains pending for Phase 11 — 45 violations in cli.py confirmed as Phase 11 scope.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| `src/corpus_analyzer/generators/advanced_rewriter.py` | 177 | `# TODO: Add timestamp` | Info | Pre-existing TODO unrelated to Phase 10 changes; provenance generation uses placeholder `"timestamp_here"` string. Not introduced by this phase. |

No blockers. The PLACEHOLDER match at rewriter.py:15 is a legitimate regex constant (`PLACEHOLDER_PATTERN`) not a code stub. The advanced_rewriter.py:147 match is a dry-run placeholder string in generated output content, also pre-existing.

### Human Verification Required

None. All verification goals for this phase are programmatically verifiable via ruff and pytest.

### Gaps Summary

No gaps. All 8 observable truths are verified, all artifacts exist and are substantive and wired, all 4 requirement IDs are satisfied, and 281 tests pass. The only remaining ruff violations are 47 in `cli.py`, which are correctly scoped to Phase 11.

## Supporting Evidence

### Ruff Check Output (full run)
```
# uv run ruff check . --output-format=concise
# All 47 errors are exclusively in src/corpus_analyzer/cli.py
# Zero violations in any other file

# uv run ruff check . --output-format=concise | grep -E "E741|E402|B017"
# (empty — zero semantic violations anywhere)

# uv run ruff check . --output-format=concise | grep -v "cli.py" | grep -v "^Found"
# (empty — zero violations outside cli.py)
```

### Test Suite Output
```
============================= 281 passed in 3.38s ==============================
