## Issues in Your Changes (BLOCKING)

### CRITICAL
(none)

### HIGH
(none)

### MEDIUM

**test:tmux scripts not included in test:all** - `package.json:20`
**Confidence**: 85%
- Problem: The new `test:tmux` and `test:tmux:integration` scripts are defined but not included in the `test:all` aggregate. While the tmux unit tests are already covered by `test:implementations` (which scans the full `tests/unit/implementations/` directory) and tmux integration tests are covered by `test:integration` (which scans `tests/integration/`), this creates a confusing contract: the dedicated scripts exist as convenience aliases but are invisible to the CI validation gate.
- Fix: Either (a) document that these are convenience-only aliases (not part of CI), or (b) add them to `test:all` and exclude the tmux subdirectory from `test:implementations`/`test:integration` to avoid double-running. Option (a) is simpler given the current overlap:
```json
// No code change needed — just document in CLAUDE.md that test:tmux 
// and test:tmux:integration are convenience aliases already covered 
// by test:implementations and test:integration respectively.
```

## Suggestions (Lower Confidence)

- **Test script overlap** - `package.json:32-33` (Confidence: 65%) — The tmux unit tests will run twice if a developer executes both `npm run test:implementations` and `npm run test:tmux` in sequence. Consider adding `--exclude='**/tmux/**'` to `test:implementations` for cleaner separation.

## Analysis Summary

This PR adds zero new npm dependencies — confirmed by:
1. No changes to `dependencies` or `devDependencies` in `package.json`
2. No changes to `package-lock.json`
3. All source imports are Node.js built-ins (`fs`, `path`, `os`, `child_process`) or existing internal modules
4. Test imports use only `vitest` (already a devDependency)
5. The runtime dependency on `tmux` is a system-level binary, appropriately handled via the injected `ExecFn` pattern with validation checks

The only package.json changes are two new test script entries (`test:tmux`, `test:tmux:integration`), which are convenience aliases. The feature knowledge explicitly states "zero new npm dependencies added" and the code confirms this claim. (avoids PF-001 — all findings surfaced rather than deferred)
