_workout_sync.py (332) -> _sync_client.py token, Firebase/GitHub client
_sync_records.py payload predicates + log decoding
_sick_tracker.py (317) -> _sick_budget.py SickHistory + rolling budget
This one was not a pure move until the fixtures followed it. Three autouse
test guards patch names by module, and all three pointed at _workout_sync:
isolate_sync_token SYNC_TOKEN_FILE -> now also on _sync_client
_no_real_firebase_config CONFIG_FILE -> now on _sync_client
_firebase_config helper (7 call sites) -> now passed _sync_client
With them stale, sync_client built a REAL client: the suite went from 14s to
over 120s and test_workout_sync_part5 asserted against live workout data
pulled from the actual backend. Fixed, the same tests run in 0.7s. Both
modules keep SYNC_TOKEN_FILE so either patch point works, and every relocated
guard target is asserted to exist.
977 tests pass at 100% branch coverage; pylint back to 8.70 after fixing the
findings the split introduced (a dropped `return None` in _parse_iso and
leftover dead imports). `screen_lock --status` unchanged.

screen_locker pushed manual workouts as "pc" and the workout app as "phone".
A role constant collides the moment a second machine takes the same role, and
after a reinstall the new install inherits the previous one's CRDT identity.
Both halves now mint a uuid once and persist it: the PC in
~/.local/share/screen_locker/.device_id, the app under SharedPreferences
'crdt.nodeId' -- the same key every sibling app uses.
The old constant survives as the legacy id and is passed to sync_log /
syncLog, so devices/<legacy>/ is skipped as this device's own rather than
re-downloaded and re-merged as a peer's on every tick. It drops to None once
that path is reclaimed.
Note the *read* loop in _workout_sync deliberately still merges every device
including this one: the PC needs its own manual workouts in the merged view,
so "skip own" would be wrong there. Only the push path and the HLC node id
move.
The test fixture redirecting the new id file is added in the same change that
introduces the constant -- without it the first test that syncs mints a uuid
into the real state dir and this machine's live sync identity is decided by
whichever test ran first. Verified: ~/.local/share/screen_locker/ held no
.device_id after a full suite run.
Verified against the live backend, not just mocks: ran the real
push_pc_workouts, which minted 57582b3b and pushed 9 records. In the RTDB the
new device's log is a strict superset of both old paths -- 0 of devices/pc/'s
10 records and 0 of devices/phone/'s 9 are missing from it.
Python: 907 tests, 100% branch coverage. workout_app: 313 tests, analyzer
clean. Pins bumped to crdt-sync-v0.6.0 / crdt_sync_dart-v0.7.0.

The morning routine is started by systemd right after boot and right after
resume, so its sync ran seconds before DHCP/DNS were up. Every such run failed
outright — and said this:
Workout sync push FAILED for 6 workout(s): network error reading
screen-locker-sync/devices — a 403 here means the token lacks
contents:write on kuhyx/syncs
Both halves of that were wrong. It was not a 403, and the token was fine: the
same six workouts pushed successfully by hand minutes later on the same token,
which reports push=true on the repo. The message cost a real investigation
chasing a permissions bug that did not exist.
- _sync_retry.with_sync_retry wraps the three sync call sites in a bounded
retry (4 attempts, 2s/4s/8s backoff — ~14s, enough for the network to come
up, short enough not to drag the routine). Verified offline in a network
namespace: three retries, then an honest give-up.
- Any GitHubSyncError retries, deliberately including RepoNotFoundError.
Classifying transient vs permanent would couple us to which exception
crdt_sync chains where; a few wasted seconds on a genuinely bad token is the
cheaper mistake.
- The push failure log now reports what actually happened. The contents:write
hint survives only for RepoNotFoundError, which is the one error that
actually implicates the repo or the token.
Retry at the application layer rather than ordering the unit after
network-online.target: the same race hits on resume, where boot ordering does
not apply, and these are user units that cannot depend on a system target.
The tests' autouse no-sleep fixture patches the module-local `sleep` name
rather than `_sync_retry.time.sleep` — the latter mutates the shared time
module object and silently disabled sleep for the whole suite, breaking an
unrelated temperature timeout test.

Sync the workout log across devices using the shared crdt-sync /
crdt_sync_dart CRDT transport (same scheme as diet_guard).
- Python: new _workout_sync.py + _temperature_status_mixin.py; wire sync
into screen_lock.py / status_view.py; add the crdt-sync git dependency
and test_sync_fixtures / test_workout_sync suites.
- Dart (workout_app): new workout_sync_service.dart, github_device_auth.dart,
sync_settings.dart with tests + fakes; settings/workout screens updated.
- docs: workstream-d-shared-crdt-transport.md.
Verification: pytest 747 passed at 100% coverage; flutter analyze clean;
flutter test passed.
