_sync.py 498 -> 165, into siblings that each own one concern:
_sync_client.py picking a backend and building the remote store
_sync_banks.py pull/merge/push for the food bank and the budget
_sync_paths.py the kuhyx/syncs wire layout, shared by both
_sync_errors.py SyncError, so _sync and _sync_client need not import
each other
The patch targets moved with the code they guard, which is the whole risk of
this commit. unittest.mock.patch and monkeypatch.setattr both bind to a
*module object*, so a patch left pointing at _sync after CONFIG_FILE and
SYNC_TOKEN_FILE moved to _sync_client redirects nothing. That is not
hypothetical here: the first run of the suite took 9m18s instead of 7s and
raised 401s, because tests were reaching the real GitHub API with a fake
token. Repointed:
conftest SYNC_TOKEN_FILE, CONFIG_FILE -> _sync_client
test_sync* GitHubSyncClient (30 patch sites) -> _sync_client
test_backend mirror/firebase_client_for -> _sync_client
The repo's own _test_guard caught the same leak independently, which is the
behaviour worth keeping: two guards, both fail-closed.
test_sync.py 482 -> 205, splitting the budget and pull/revision classes into
siblings and the shared fakes into _sync_fakes.py.
conftest.py 284 -> 155, moving the Tk/gatelock fixtures to _gate_fixtures.py.
Importing them back is what registers them (pytest_plugins is an error in a
non-root conftest), and they are named in __all__ because ruff's autofix
otherwise deletes the "unused" import and silently disables Tk blocking --
it did exactly that once here. Verified afterwards with a canary asserting
_gatelock.tk is still a MagicMock, not merely that the suite passes.
Verified: 692 tests / 100% coverage unchanged; ~/.local/share/diet_guard
byte-identical before and after the run; cd /tmp && python3 -m diet_guard sync
-> 402 entries, exit 0. Gate 47 -> 44.
