# Review R004 — Plan Step 4

Verdict: approved with guardrails.

The Step 4 plan is appropriate for this task's quality gate: run the full suite with `make test`, run `make lint`, fix any failures, and confirm `make build` passes. The referenced Make targets exist and cover the expected commands.

Required execution notes:

- Treat any failure as a blocker; do not mark Step 4 complete until `make test`, `make lint`, and `make build` all pass in this worktree.
- If lint tooling is missing or environment-specific, record the exact failure in `STATUS.md` and resolve/install rather than skipping the check.
- If failures require code or snapshot changes, rerun the affected command and then the full Step 4 gate again.
- Record the final command outcomes in `STATUS.md` so Step 5 can summarize verification cleanly.

No plan blocker.
