The cleanup in setupSyncTestDB ran DELETE FROM sync_queue WHERE true —
a table-wide wipe that discards REAL devices' pending offline entries
on every suite run. Same class as the 2026-10-14 reading_history
incident the standing rules ban. The test's own queue items cascade
from its 'Test %'-named device, so the wipe is redundant for cleanup —
scoped it to those devices (defense in depth ahead of the cascade).
Flagged during H1 verification: the line executed during an in-
container suite run this session; any device with pending offline
queue entries at that moment should re-push on its next sync.
