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.

pylint scored the suite at 8.58/10, and 277 of the ~300 findings were missing
docstrings -- every one of them in crdt_sync/tests/, none in library code.
ruff exempts tests from the docstring rules, so the two linters disagreed and
the score sat well below the bar.
Rather than silence pylint to match ruff, every test class, test function and
stub method now says what it pins. Stub arguments that exist only to match a
real signature are underscore-prefixed, which is the documented way to say
"deliberately unused" and clears the unused-argument findings too.
No behaviour change: 259 tests, still 100% branch coverage.

Extracted and generalized from diet_guard's existing tombstone-merge scheme
and GitHub Contents API client, extended with per-field HLC LWW so the same
library can also cover todo's mutable notes and wake_alarm's single-value
sync (Workstream D scoping decision, 2026-07-04). 100% branch coverage,
clean ruff/mypy/pylint/bandit.
