# Phase 22: Name Filtering Verification Report

**Phase Goal:** Add name-based filtering to hybrid search so users can narrow results to specific named constructs (functions, classes, methods) across all search interfaces.
**Verified:** 2026-02-24T17:40:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| #  | Truth | Status | Evidence |
|----|-------|--------|----------|
| 1  | `hybrid_search(name='foo')` returns only chunks whose `chunk_name` contains 'foo' (case-insensitive) | VERIFIED | `TestHybridSearchNameFilter::test_name_filter_returns_matching_chunks` passes; engine.py lines 136-141 implement the filter |
| 2  | `hybrid_search(name='ClassName.method')` returns only the matching method chunk | VERIFIED | `TestHybridSearchNameFilter::test_name_filter_dot_notation` passes; asserts `len(results) == 1` with exact match |
| 3  | `hybrid_search(query='')` with `name='foo'` returns name-matching chunks without requiring text match | VERIFIED | `TestHybridSearchNameFilter::test_empty_query_with_name_skips_text_filter` passes; engine.py line 82-99 implements table-scan fallback for empty query |
| 4  | `hybrid_search(name=None)` is unchanged from current behaviour | VERIFIED | `TestHybridSearchNameFilter::test_name_none_is_noop` passes; `if name:` guard at line 136 is falsy for None |
| 5  | `corpus search --name foo <query>` returns only results whose `chunk_name` contains 'foo' | VERIFIED | `test_search_name_filter_passed_to_engine` and `test_search_name_composes_with_source_filter` pass; cli.py line 404 passes `name=name_filter` |
| 6  | `corpus search --name foo` (no positional query) is valid and returns name-matching results | VERIFIED | `test_search_name_only_no_query_is_valid` and `test_search_name_only_passes_empty_query_to_engine` pass; cli.py lines 365-368 implement guard + `effective_query=""` |
| 7  | `corpus search` (no query, no `--name`) exits 1 with error message | VERIFIED | `test_search_no_query_no_name_exits_error` passes; cli.py lines 365-367 print error and raise Exit(1) |
| 8  | MCP `corpus_search` with `name='foo'` passes `name=` through to `hybrid_search` | VERIFIED | `test_corpus_search_name_forwarded_to_hybrid_search` and `test_corpus_search_name_none_forwards_none` pass; server.py line 93 passes `name=name` |

**Score:** 8/8 truths verified

### Required Artifacts

| Artifact | Provides | Exists | Substantive | Wired | Status |
|----------|----------|--------|-------------|-------|--------|
| `src/corpus_analyzer/search/engine.py` | `hybrid_search()` with `name` parameter; empty-query table-scan path | Yes | Yes — 191 lines, full implementation | Yes — called by CLI and MCP | VERIFIED |
| `tests/search/test_engine.py` | TDD tests for name filter and empty-query name-only search | Yes | Yes — `TestHybridSearchNameFilter` with 7 tests, `named_table` fixture | Yes — imported and run in test suite | VERIFIED |
| `src/corpus_analyzer/cli.py` | `--name/-N` CLI flag; `query` made Optional; guard clause | Yes | Yes — 1146 lines; `name_filter` at lines 354-362; guard at 365-368 | Yes — `name=name_filter` at line 404 | VERIFIED |
| `src/corpus_analyzer/mcp/server.py` | `name: Optional[str]` MCP parameter | Yes | Yes — `name: Optional[str] = None` at line 48; docstring updated | Yes — `name=name` at line 93 | VERIFIED |
| `tests/cli/test_search_status.py` | TDD tests for `--name` CLI flag and optional query | Yes | Yes — 6 new tests for name-filter scenarios | Yes — all pass in test suite | VERIFIED |
| `tests/mcp/test_server.py` | TDD tests for MCP `name` parameter | Yes | Yes — 3 new tests for NAME-02 | Yes — all pass in test suite | VERIFIED |

### Key Link Verification

| From | To | Via | Status | Evidence |
|------|----|-----|--------|----------|
| `tests/search/test_engine.py` | `src/corpus_analyzer/search/engine.py` | `CorpusSearch.hybrid_search(name=...)` | WIRED | Pattern `hybrid_search.*name=` found at lines 497, 504, 511, 518, 525, 531, 538 of test file |
| `src/corpus_analyzer/cli.py` | `src/corpus_analyzer/search/engine.py` | `search.hybrid_search(..., name=name_filter)` | WIRED | `name=name_filter` at cli.py line 404; `hybrid_search` called at line 396 |
| `src/corpus_analyzer/mcp/server.py` | `src/corpus_analyzer/search/engine.py` | `engine.hybrid_search(..., name=name)` | WIRED | `name=name` at server.py line 93; `engine.hybrid_search` called at line 86 |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| NAME-01 | 22-01, 22-02 | `corpus search --name <fragment>` CLI flag; case-insensitive substring match on `chunk_name`; composable with all existing filter flags | SATISFIED | `--name/-N` option in cli.py; `name_filter` forwarded to `hybrid_search()`; `test_search_name_composes_with_source_filter` passes |
| NAME-02 | 22-02 | MCP `corpus_search` accepts `name: Optional[str]` parameter; same case-insensitive substring match semantics | SATISFIED | `name: Optional[str] = None` in server.py; `name=name` forwarded; 3 MCP tests pass |
| NAME-03 | 22-01, 22-02 | `corpus search --name foo` (no positional query) is valid; lists all chunks matching the name filter | SATISFIED | Query made Optional in CLI; `effective_query=""` guard; `test_search_name_only_no_query_is_valid` passes; empty-query table-scan path in engine.py |

All three phase-22 requirements (NAME-01, NAME-02, NAME-03) are marked `[x]` complete in REQUIREMENTS.md traceability table.

No orphaned requirements: REQUIREMENTS.md maps NAME-01, NAME-02, NAME-03 exclusively to Phase 22. No additional IDs for Phase 22 are listed without a plan claiming them.

### Anti-Patterns Found

None. Scanned all modified files for TODO/FIXME, empty implementations, placeholder returns, and stub handlers.

- `engine.py`: Full implementation with `is_empty_query` branch, name filter block, and min_score/sort_by passes. No stubs.
- `cli.py`: Guard clause, `effective_query`, `name=name_filter` forwarded. No stubs.
- `server.py`: `name: Optional[str] = None` parameter; `name=name` forwarded to engine. No stubs.

### Human Verification Required

None. All phase-22 behaviours are programmatically verifiable:

- Name filter semantics are covered by unit tests with a real LanceDB table fixture.
- CLI `--name` option is verified via `typer.testing.CliRunner` (no live Ollama needed).
- MCP name forwarding is verified with mock engine.
- Full test suite (398 tests) passes with zero failures.
