### Round 1 findings — status

| # | Finding | Status |
|---|---------|--------|
| 1 | Redundant inline import in `run_ceo()` | **Fixed** — removed, module-level import at line 47 is canonical |
| 2 | `type(repo_map_config)(...)` in cli.py should be `dataclasses.replace()` | **Accepted** — still present but functionally correct; cosmetic |
| 3 | Greedy truncation leaves ~5-10% budget slack | **Accepted** — design trade-off for V1 |

### Round 2 fixes verified

| # | Finding (from other reviewers) | Fix verified |
|---|-------------------------------|--------------|
| 1 | Decision Gate phase missing `_inject_repo_map()` | ✅ Present at line 4676 |
| 2 | `read_text()` has no file size guard | ✅ `_MAX_PARSE_SIZE = 1_000_000` guards both Python and JS/TS extractors |
| 3 | Redundant local import in `run_ceo()` | ✅ Removed |

### Non-blocking observations

1. **`type(repo_map_config)(...)` in cli.py line 1283**: Still using `type(x)(...)` instead of `dataclasses.replace()`. Not wrong, just ugly. The kind of thing that makes a reader pause and ask "why?" when `replace(repo_map_config, max_tokens=max_tokens)` says exactly what it means. Style, not correctness.

2. **Duplicated comment on line 27-28 of repo_map.py**: The "Hardcoded sensitive file patterns" comment appears twice — once as a stale fragment above `_MAX_PARSE_SIZE` and once correctly above `SENSITIVE_PATTERNS`. Copy-paste artifact.

### Test results

- **660 tests passing**, zero failures
- Integration tests use real `git init` — no mock theater
- Size guard tests for both Python and JS/TS extractors present

VERDICT: approve

FINDINGS:
- [src/colonyos/cli.py:1283]: `type(repo_map_config)(...)` should be `dataclasses.replace()` for clarity — cosmetic, not blocking
- [src/colonyos/repo_map.py:27]: Duplicated "Hardcoded sensitive file patterns" comment (copy-paste artifact) — cosmetic

SYNTHESIS:
All Round 1 findings are resolved or accepted. The code is correct, simple, and follows every pattern in the existing codebase. The data structures are right — `FileSymbols` with a flat list of `Symbol` that has recursive `children` for class methods. The pipeline is linear and stateless: walk → parse → rank → truncate. No hidden state, no premature abstractions, no dependency gymnastics. The `_MAX_PARSE_SIZE` guard closes the OOM vector on large files. All 8 pipeline phases now have `_inject_repo_map()` calls. The `try/except` wrapper around `generate_repo_map` in the orchestrator means a bug in the map module can never crash a pipeline run — fail-closed, as it should be. 660 tests pass with real git repos, not mocked garbage. The two remaining cosmetic issues (the `type()` constructor and a duplicated comment) are not worth blocking a ship. This is ready.
