The PC push aborted before it ever tried Firebase whenever the GitHub PAT
was missing ("Workouts NOT synced: no sync token"), so once the PAT was lost
this machine published nothing although Firebase was configured and live.
The phone has not written the GitHub repo since 2026-08-21.
- sync_client() / sync_client_or_reason(): firebase_client_for("screen_locker")
only, proven with can_access_remote(), healed once from a sibling app's
session, else a warning naming what will not sync (push AND pull) plus a
recorded degraded source. No config -> warning, no fallback.
- _manual_push and scripts/tombstone_sync_record.py take their client from
sync_client_or_reason(); the push result carries the reason.
- Deleted: read_sync_token, remote_client, the mirror client, _push_outcome
(the half-landed-push case no longer exists), SYNC_TOKEN_FILE and
SYNC_REPO_OWNER/NAME, the sync_token test fixture. Status backend is
"firebase" or "none".
- crdt-sync pinned to v0.9.2 in pyproject, requirements.txt and
install_systemd.sh (the installer still said v0.9.0).
kuhyx/syncs/screen-locker-sync is left untouched as an archive; no code
reads it.

`flutter test` runs on a Linux host, so credentialStore()'s Platform.isLinux
branch wrote $HOME/.config/screen_locker/firebase_auth.json -- the refresh
token the screen-locker daemon signs in with. firebase_backend_google_test's
"stores the account under the email Firebase reports" case overwrote it with
the fixture token 'refresh' on every local run; the daemon only survived by
self-healing from a cached token.
Dart:
- lib/services/desktop_config_dir.dart: one resolver, desktopConfigRoot(),
for every desktop path (the credential file's read/write/delete and the
~/.config/crdt-sync account read). @visibleForTesting override; under
FLUTTER_TEST it throws StateError if the root is, or is inside, the real
$HOME/.config -- so a test that bypasses the override fails loudly instead
of writing. HOME unset now yields null instead of a cwd-relative .config.
- The crdt-sync read resolves the root outside its catch-all, so the guard
cannot be swallowed as "not connected".
- test/flutter_test_config.dart gives every test its own temp config root.
- The Google sign-in test now asserts the token landed in that temp root.
- path_provider is unbound under flutter test (MissingPluginException), so
the getApplicationSupportDirectory callers cannot reach live dirs.
Python (tests only): isolate_sync_token now patches every import-time
binding of SYNC_TOKEN_FILE (_constants, _manual_push, _sync_status were
missed), and test_home_isolation scans all runtime modules for any Path
still bound inside the real ~/.config/screen_locker.

`requires-python` and the CI pin already said 3.14, but ruff, mypy and pylint
were still grading against 3.10 -- three tools judging an interpreter nothing
runs any more, and ruff withholding the pyupgrade fixes that only become safe
at the newer target. `pin_ci_python.py` rewrites exactly these three knobs.
What the stale target was hiding: 118 sites on `datetime.timezone.utc` instead
of `datetime.UTC` (UP017), two classes still written with `Generic[...]` rather
than PEP 695 syntax, and ruff's stable formatter applying PEP 758 --
`except (A, B):` becomes `except A, B:`. That last one makes the source
3.14-only at the syntax level, which is what `requires-python = ">=3.14"`
already promised; kuhy chose it deliberately over holding ruff a release back
(2026-08-29).
The PEP 695 fix needed a hand: ruff rewrote `class WidgetGroup(Generic[_W])`
to `class WidgetGroup[W: tk.Misc]` but left the body annotated with the
module-level `_W`, a *different* type variable -- mypy caught it as "a function
returning TypeVar should receive at least one argument containing the same
TypeVar". Renamed the body to the new parameter, gave `FrameGroup.__init__`
the concrete `list[tk.Frame]` it always wrapped, and deleted the two now-dead
module-level TypeVars.
ruff, ruff-format, mypy --strict and both pylint passes clean at the new target.
