# Review by Linus Torvalds (Round 5)

All 291 tests pass. Now let me write the review.

VERDICT: approve

FINDINGS:
- [src/colonyos/repo_map.py:SENSITIVE_PATTERNS]: `.env`, `.env.*`, `.env*` — three patterns where one (`.env*`) covers all three cases. It's harmless redundancy, the kind of thing I'd point at and laugh but not block a merge over. The `fnmatch` library handles it fine.
- [src/colonyos/repo_map.py:truncate_to_budget]: Calls `format_tree([fs])` per file inside the greedy loop — that's O(n) string allocations for what is essentially a "can this fit?" check. For 2000 files of tiny tree output this is noise, but if someone ever bumps max_files to 10k it'll show up in a profile. Not a blocker — the 2000 cap saves you.
- [src/colonyos/repo_map.py:_format_args]: Skips `self`/`cls` by string comparison, which is correct for 99.9% of real Python code. Nobody's naming their regular parameter `self` and if they are, they deserve what they get.
- [src/colonyos/repo_map.py:rank_by_relevance]: The scoring function is simple, deterministic, and readable. No machine learning wizardry, no hidden state. I can read the weights and understand what it'll do. That's how scoring should work.
- [src/colonyos/repo_map.py:_format_expr]: Uses `ast.unparse()` with a fallback chain. Clean. The `except Exception` is broad but this is a formatting helper — crashing because of some weird AST node would be stupid.
- [src/colonyos/config.py:_parse_repo_map_config]: Validates `max_tokens >= 1` and `max_files >= 1` with clear error messages. Follows the exact same pattern as every other `_parse_*_config` function in this file. Good.
- [src/colonyos/orchestrator.py:_inject_repo_map]: Dead simple — 6 lines, checks for empty, appends formatted block. This is what an injection helper should look like. It follows `_inject_memory_block` exactly.
- [src/colonyos/orchestrator.py:_run_pipeline]: Single `generate_repo_map()` call at the top, result threaded through all 8 phases. Exception wrapped in try/except so a map failure never kills the pipeline. Correct.
- [src/colonyos/orchestrator.py:run_ceo]: CEO generates its own map independently because it runs outside `_run_pipeline()`. This is the right call — CEO is a separate entry point.
- [src/colonyos/cli.py:map]: Uses `dataclass_replace` for the `--max-tokens` override instead of mutating the config object. Clean.
- [tests/test_repo_map.py]: 95 tests using real `git init` repos, not mocking the filesystem. That's how you test code that talks to git.

SYNTHESIS:
This is straightforward, well-structured code that does exactly what the PRD says and nothing more. The data structures are right — `FileSymbols` contains what you need, `Symbol` is a simple tree node, `RepoMap` is a bag of both. The control flow is linear and obvious: walk files → extract symbols → rank → truncate → format. No premature abstraction, no clever metaprogramming, no unnecessary class hierarchies. The function boundaries are clean — each function does one thing, takes obvious parameters, returns an obvious type. The error handling is defensive without being paranoid — subprocess timeouts, file read failures, syntax errors, and large-file guards are all handled at the right layer. The orchestrator integration is minimal — one new helper function, one generation call, and consistent injection points across all phases. The test suite is comprehensive and tests real behavior against real git repos. The whole thing is 738 lines of module code and it reads like it could have been 738 lines — no bloat, no dead code, no unnecessary indirection. Ship it.
