 ## Commit convention
 
 - Use Conventional Commits for all commit messages.
-  Before writing a commit message, read `docs/conventional-commits.md`.
 - Keep commit messages about the Git history, not the forge workflow.
   Include external references only when they are stable context for the change.
 - When writing commit messages, NEVER auto-add your agent name as co-author.

   Preserve `git-subtree-dir` and `git-subtree-split` trailers on Pi vendor commits.
 - The default Pi model for NixOS user configuration is set in `configs/nixos/modules/shell/pi/default.nix`, not in vendored Pi source.
+- The `monorepo` and `status` libraries do not have `README.md` files.
