## VERDICT: approve

## Completeness

All 19 functional requirements verified and implemented. All 7 task groups (28 subtasks) marked complete. **101/101 tests pass** (92 repo_map + 5 CLI + 4 orchestrator).

## Findings

### 1. [src/colonyos/orchestrator.py] — Missing injection in 2 of 6 phases (Low)

`_inject_repo_map()` is called for Plan, Implement, Review, and Fix phases but **not** for Decision Gate (line 4668) or Deliver (line 4719). FR-15 says "pass it through to all prompt-building functions." Practical impact is low since those phases are less exploration-heavy, but it's a 2-line fix for consistency.

### 2. [src/colonyos/orchestrator.py] — Dead `repo_map_text` parameter (Low)

`_run_sequential_implement` accepts `repo_map_text: str = ""` (line 776) but no caller passes it. The main pipeline path handles injection at the call site, so this parameter is unused dead code.

### 3. [src/colonyos/repo_map.py] — `generate_repo_map()` ignores `config.enabled` (Informational)

By design: the `enabled` check lives in the orchestrator, not the generator. This is correct — the CLI `colonyos map` should work regardless of the injection toggle. Documented by `test_disabled_config_still_generates`.

### 4. [src/colonyos/repo_map.py] — Greedy truncation uses break instead of skip (Non-blocking, V1.1)

`truncate_to_budget` breaks on the first file that exceeds remaining budget. A skip-and-continue approach would pack more content. Since files are relevance-ranked, the most important files are already included, so practical impact is marginal.

### 5. [src/colonyos/repo_map.py] — JS/TS regex enforces top-level only (Informational)

`^export` with `re.MULTILINE` correctly matches only unindented exports, consistent with the PRD's "top-level exports only for V1" decision. Won't catch `declare module` nested exports — fine for V1.

## SYNTHESIS

This is a clean, well-structured module that solves the cold-start problem the right way: a deterministic, zero-dependency structural extraction pipeline that runs once per tick. The key architectural choice — programmatic injection instead of template placeholders — is correct and avoids the `str.format()` `KeyError` trap that would have hit immediately on any Python signature containing `{`. The test coverage is excellent (101 tests, ~2:1 test-to-code ratio), including real `git init` integration tests rather than just subprocess mocks. The two missing injection sites (Decision Gate, Deliver) are the only substantive gap, and they're low-impact since those phases are less exploration-dependent. The relevance ranking is appropriately simple — keyword overlap with scored tiers (path match > basename > symbol overlap) — and doesn't try to be clever with embeddings or TF-IDF, which is the right call for a static context artifact. Ship it.
