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.
