# v1.2 Graph Linker — Milestone Audit

**Milestone:** v1.2 Graph Linker
**Audited:** 2026-02-24T03:20:00Z
**Status:** ✅ passed
**Scope:** Phases 7–8

## Requirements Coverage

| Requirement | Description | Phase | REQUIREMENTS.md | VERIFICATION.md | SUMMARY Frontmatter | Final Status |
|-------------|-------------|-------|-----------------|-----------------|---------------------|--------------|
| GRAPH-01 | Developer can query upstream relationships via `corpus graph <slug>` | 7 | `[x]` Complete | codebase-verified¹ | n/a¹ | **satisfied** |
| GRAPH-02 | Developer can query downstream relationships via `corpus graph <slug>` | 7 | `[x]` Complete | codebase-verified¹ | n/a¹ | **satisfied** |
| GRAPH-03 | `corpus index` auto-extracts and persists `## Related Skills/Files` edges | 7 | `[x]` Complete | codebase-verified¹ | n/a¹ | **satisfied** |
| GRAPH-04 | Slug ambiguity resolved by closest-prefix; duplicate slugs warned during index | 7 | `[x]` Complete | codebase-verified¹ | n/a¹ | **satisfied** |
| GRAPH-05 | Developer can list all duplicate slug collisions via `corpus graph --show-duplicates` | 7 | `[x]` Complete | codebase-verified¹ | n/a¹ | **satisfied** |
| CLEAN-01 | Dead `use_llm_classification` parameter removed from `index_source()` | 8 | `[x]` Complete | passed (4/4) | `[CLEAN-01]` | **satisfied** |

¹ Phase 7 was completed before GSD workflow was active (merged to main pre-GSD). No VERIFICATION.md or SUMMARY.md exists for Phase 7. Requirements verified directly against codebase and confirmed by integration checker (see below).

**Score: 6/6 requirements satisfied. No orphaned requirements.**

## Phase Verification Summary

### Phase 7: Graph Layer
**Note:** Completed before GSD workflow was active. No VERIFICATION.md.

**Codebase evidence (direct verification):**

| Artifact | Expected | Status | Evidence |
|----------|----------|--------|----------|
| `graph/extractor.py` | `extract_related_slugs()` function | VERIFIED | `src/corpus_analyzer/graph/extractor.py:27` |
| `graph/registry.py` | `SlugRegistry` with `.build()`, `.resolve()`, `.duplicates` | VERIFIED | `registry.py:170` — `resolve()` uses `os.path.commonpath` for closest-prefix |
| `graph/store.py` | `GraphStore` with `.write_edges()`, `.edges_from()`, `.edges_to()`, `.search_paths()` | VERIFIED | All methods present |
| `cli.py` | `corpus graph <slug>` command | VERIFIED | `cli.py:342` — `graph_command()` with upstream/downstream display |
| `cli.py` | `corpus graph --show-duplicates` flag | VERIFIED | `cli.py:337-353` |
| `ingest/indexer.py` | `extract_related_slugs` called during indexing | VERIFIED | `indexer.py:414` |
| `ingest/indexer.py` | `registry.resolve()` + `graph_store.write_edges()` per file | VERIFIED | `indexer.py:419,424` |
| `cli.py` | Duplicate slug warning during `corpus index` | VERIFIED | `cli.py:131` — `⚠️` yellow warning for within-source duplicates |

### Phase 8: Cleanup
**Verification:** PASSED (4/4 observable truths)

- ✅ Zero occurrences of `use_llm_classification` in `src/` and `tests/`
- ✅ Test suite: 281 passed, 0 failures (baseline 282 − 1 deleted test)
- ✅ `index_source()` signature: no `use_llm_classification` parameter
- ✅ `classify_file` called with `use_llm=False` (preserves rule-based classification)

## Cross-Phase Integration

**Integration checker result:** 6/6 requirements WIRED, 3/3 E2E flows COMPLETE

### Key Wiring Verified

| From | To | Via | Status |
|------|----|-----|--------|
| `graph/extractor.py` | `ingest/indexer.py` | `extract_related_slugs()` import | WIRED |
| `graph/registry.py` | `ingest/indexer.py` + `cli.py` | `SlugRegistry` import | WIRED |
| `graph/store.py` | `ingest/indexer.py` + `cli.py` | `GraphStore` import | WIRED |
| Phase 8 CLEAN-01 removal | Phase 7 graph wiring | `graph_store` + `registry` params survive intact | COMPATIBLE |

**Critical check:** Phase 8 removed `use_llm_classification` from `index_source()` without disturbing Phase 7's `graph_store` and `registry` keyword-only parameters. The `cli.py` call site at lines 191-196 passes both correctly.

### E2E Flows

| Flow | Description | Status |
|------|-------------|--------|
| **Index → Graph** | `corpus index` → extract slugs → resolve → write edges to `graph.sqlite` | ✅ COMPLETE |
| **Query graph** | `corpus graph <slug>` → `edges_to()` + `edges_from()` → upstream/downstream display | ✅ COMPLETE |
| **Show duplicates** | `corpus graph --show-duplicates` → `SlugRegistry.build()` → list all collisions | ✅ COMPLETE |

## Tech Debt

| Phase | Item | Severity |
|-------|------|----------|
| 08-cleanup | 42 pre-existing mypy errors (unrelated to modified files) | Low — future cleanup |
| 08-cleanup | 529 pre-existing ruff errors (unrelated to modified files) | Low — future cleanup |

**No critical tech debt. No blockers.**

---

## Audit Notes

- Phase 7 lacks a formal VERIFICATION.md (predates GSD workflow). All GRAPH requirements verified directly from codebase and confirmed by integration checker with 100% coverage.
- `corpus graph --show-duplicates` intentionally shows all duplicates (including cross-source) while `corpus index` warning shows only within-source duplicates. This asymmetry is by design and consistent.
- Test suite at 281 tests (Phase 8 deleted 1 test for the removed field).
