# R&D Cleanup Post-verification entropy reduction. Runs after a task has passed verification. Detects code rot introduced during the build, applies mutations, re-verifies, and rolls back on failure. ## The Iron Laws ``` 1. NEVER MODIFY TEST FILES OR PRE-REGISTRATION DOCUMENTS 2. NEVER AUTO-COMMIT — CHANGES STAY IN THE WORKING TREE 3. ROLL BACK ALL TOUCHED FILES ON ANY NON-PASS VERDICT 4. EMPTY CANDIDATE LIST → SKIP IMMEDIATELY, NO NO-OP EDITS ``` ## Four Detection Categories Run all four on every task. ### 1. Dead Functions / Unused Exports Use language-specific tooling when available; fall back to LLM diff review for unsupported languages. | Language | Tool | |----------|------| | TypeScript / JS | `ts-prune`; or Grep for exported symbol with no inbound import | | Python | `ruff check --select F401,F841` on changed files | | Bash, Markdown, other | LLM diff review — reason about whether any function/variable introduced in this build is called from outside its own file | A finding: symbol defined in the diff with zero references from project entry points. ### 2. Orphan Files 1. Extract changed files from `$RND_DIR/builds/T<id>-manifest.md`. 2. Grep for each new file's basename and exported identifiers across the project. 3. A file is an orphan if no other file imports or references it AND it is not itself an entry point (`main`, `index`, `__main__`, CLI script in `package.json`/`pyproject.toml`). ### 3. Duplicate / Parallel Implementations LLM diff review only. R
