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.

Two gaps against the 100% bar. The first is mine: --log-manual-workout's
dispatch branch had no test, so nothing checked that the flag's own name is
stripped before the args are forwarded, or that the exit code is the logger's.
The second predates this work. `_record_decision` annotates the DECISION line
with any backend it could not read, which is the thing that distinguishes
"weekly=0/5, measured" from "weekly=0/5, unreadable" -- the exact confusion
that hid the 2026-08 outage -- and that branch was never exercised. Now both
directions are: named when a source is degraded, absent when none are.
test_sync_degradation.py was at the 250-line cap, so the new class lives in
test_sync_degradation_part2.py.
