+- `alef-sync-versions`: pass `--no-regen` so the hook only writes version-stamped manifest files. Without the flag, `alef sync-versions` also fires a full `alef generate` pass — desirable for `task set-version` but the wrong shape for a per-commit hook (the regen is slow and any unrelated codegen drift surfaces as "files modified by this hook" on every commit, causing the hook to fail even when no real sync work needs doing).
