Each step: specific file(s) to create/modify, what changes to make, why.\nKeep steps small enough to implement and verify independently.\n\n### Critical Files\n3\u20135 files the implementer MUST read before starting:\n- `path/to/file.rs`\n\n### Risks\nEdge cases, breaking changes, or tricky integration points to watch for.\n\nBe specific: name files, functions, types, line numbers where helpful.\nDo NOT include raw file contents \u2014 summarize and reference by path.",
