The three Python packages pinned ruff twice at different versions:
requirements.txt at 0.16.7, .pre-commit-config.yaml at v0.15.2. Only the
older one ever ran, so `select = ["ALL"]` was enforced two minor versions
behind. Measured before aligning: v0.15.2 reports 0 findings, every 0.16.x
reports CPY001 on each file -- 70 crdt-sync, 23 freedays, 71 gatelock, and
no other rule.
Resolved by adding the notice rather than ignoring the rule, so the gate
keeps its teeth.
Two gatelock modules sat at exactly the 250-line cap, so a one-line header
tipped them to 251. Both are split along a real seam rather than shaved:
_widget_fills.py colour arithmetic over LockConfig, no tkinter import
_surfaces_focus.py selects among existing surfaces, never mutates them
The focus split keeps _surfaces.py's documented containment (it stays the
only module that creates, moves or destroys windows), and the static guard
in test_recovery_invariants.py globs _surfaces*.py, so the new sibling is
covered with no list to extend. widgets.py re-exports the fills helpers,
which keeps gatelock.widgets the single public surface its tests import.

Cut at concern boundaries, not line counts: test_sync_skips.py holds the five
cases where a peer's pushed file is missing, corrupt, wrong-shaped or our own
— one story about what sync_log declines to merge — rather than an arbitrary
half of the original class.
