# Review by Principal Systems Engineer (Google/Stripe caliber) (Round 2)

There's a redundant local import at line 2240 (`run_ceo`). The function already has `generate_repo_map` available from the top-level import at line 47. The local import is harmless (Python caches it) but it's dead code — someone might later remove the top-level import thinking the local one is the canonical source, or vice versa.

Now let me write the review:

## Review: Principal Systems Engineer

I've reviewed the full diff (2,497 lines added across 11 files), the PRD's 19 functional requirements, and run the test suite (655 tests, all passing).

### Checklist Assessment

**Completeness:**
- ✅ FR-1 through FR-14: Core map generation, extraction, config — all implemented
- ✅ FR-15: Pipeline injection in Plan, Implement (sequential + parallel), Review, Fix, Deliver, CEO — 7 injection sites
- ⚠️ FR-15: Decision Gate phase inside `_run_pipeline()` (line 4680) is **not** injected. `repo_map_text` is in scope but `_inject_repo_map` is never called between `_build_decision_prompt` and `run_phase_sync`.
- ✅ FR-16 through FR-19: Injection pattern, enabled guard, formatting, CLI — all correct

**Quality:**
- ✅ 655 tests pass, zero regressions
- ✅ No linter issues observed
- ✅ Follows existing conventions (`_inject_memory_block` pattern, Click CLI, config dataclass)
- ✅ Zero new dependencies
- ⚠️ Redundant `from colonyos.repo_map import generate_repo_map` at line 2240 (already imported at line 47)

**Safety:**
- ✅ No secrets in code
- ✅ Hardcoded sensitive denylist applied before user patterns (can't be overridden)
- ✅ `ast.parse()` only, never `eval`/`exec`
- ✅ 30s subprocess timeout, graceful degradation on all I/O errors
- ⚠️ `read_text()` has no file size bound — a pathological tracked file (e.g., generated 200MB Python file) would be fully loaded into memory. Low probability but high blast radius at 3am.

VERDICT: request-changes

FINDINGS:
- [src/colonyos/orchestrator.py:4680]: Decision Gate phase in `_run_pipeline()` missing `_inject_repo_map(system, repo_map_text)` call. FR-15 requires all phases; `repo_map_text` is in scope but unused here. The Decision Gate reads code to assess merge-readiness — structural context is arguably *more* valuable here than in Deliver. Two-line fix: add `system = _inject_repo_map(system, repo_map_text)` after line 4680.
- [src/colonyos/orchestrator.py:2240]: Redundant local `from colonyos.repo_map import generate_repo_map` inside `run_ceo()` — the same symbol is already imported at module level (line 47). Remove the local import to avoid confusion about the canonical import site.
- [src/colonyos/repo_map.py:159,330]: `file_path.read_text()` has no size guard. A tracked Python/JS file larger than ~10MB (e.g., generated code, vendored bundles) would cause memory pressure. Recommend skipping files where `file_path.stat().st_size > 1_000_000` before calling `read_text()`, returning a size-only `FileSymbols` instead. Non-blocking for V1 but should be addressed before monorepo deployments.

SYNTHESIS:
This is a well-engineered module that solves a real cold-start problem with the right architectural choices: deterministic extraction, zero dependencies, programmatic injection, and fail-open error handling. The test coverage is strong (101+ repo map tests including real `git init` integration tests), the config follows existing patterns exactly, and the injection sites are comprehensive across 7 of 8 pipeline phases. The one blocking gap is the Decision Gate — a two-line fix. The unbounded `read_text()` is the kind of thing that works fine on normal repos but creates a silent OOM at 3am on a monorepo with a vendored 50MB generated file; adding a 1MB size guard before parsing would close that operational risk. Overall, this is close to ship-ready — one fix and it's good to go.
