The hook entry was an absolute /home/kuhy/utils path, copied from a config
written for ~/.claude where it only ever ran locally. On an Actions runner
that is exit code 127 — "No such file or directory" — so gatelock-precommit
and crdt-sync-precommit failed on every commit of this refactor while the
hook silently checked nothing. Now repo-relative, matching the sibling hooks
(`entry: scripts/check_subproject_scope.sh`): pre-commit always runs from the
git root, so it resolves the same in both places.
Fixing that made the CI configs runnable locally, and `--all-files` then found
what per-file runs had missed — ruff pruning imports that exist *for* their
re-export. `import crdt_sync` was broken three separate ways (FileSyncStateStore,
encode_key, FileCredentialStore). Each affected module now states an explicit
__all__ so the autofixer cannot take them again, and the two files that pushed
past the cap once __all__ was added are split further:
_firebase.py 260 -> 247 + _fberrors 25
_sync.py 257 -> 188 + _syncargs 91
Test patch targets followed the code they patch: gatelock._outputs.shutil ->
_xrandr.shutil, gatelock._arbiter.Path -> _claims.Path.
gatelock and crdt-sync both pass `pre-commit run --all-files` in full;
389 and 259 tests at 100% branch coverage; the root gate exits 0.

A refactor without a gate silently regrows, so this is the part that makes the
cap stick. Until now the repo had no root .pre-commit-config.yaml at all --
`git commit` ran zero hooks, and the five subproject configs only covered their
own directories.
Adds a root config wiring scripts/check_file_length.sh as a local hook, and
carries the same hook in each of the five subproject configs so committing
with one of those is gated too. Staged files only, so an unrelated commit
never breaks on a violation it did not introduce; exit 1, not a warning; no
baseline and no allowlist, since those are suppressions.
Verified in a throwaway worktree, both directions:
- a staged 261-line file fails the commit (exit 1, HEAD unchanged, no
commit object created)
- a staged 200-line file commits normally (exit 0)
The 44 files still over the cap cannot block this: the hook only ever sees
what a commit touches.
