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.

The Python and Dart test suites each only verified round-tripping through
their own encoder/decoder, so a Record.to_dict()/toJson() key mismatch
between the two (deleted_hlc vs deletedHlc) would have gone undetected
despite being the exact thing this shared library exists to prevent. Pin
one canonical fixture in both suites so a future divergence fails loudly
on at least one side. Also add a test for a valid-JSON-but-wrong-shape
remote push, exercising the full (ValueError, KeyError, TypeError) skip
path, not just JSON syntax errors.

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.
