"""The RunnerUp backfill credits each fill through the shared ``on_ingested``.

Regression for 2026-09-16: a run synced off the phone at 20:25 was appended
to the log but earned only the weekly-surplus bonus (+1h per workout above
the weekly minimum), which was 0 that early in the week -- the shutdown hour
stayed at 20:00 while the daily base reset would have derived 22:00 from the
very same log. Every fill now goes through the same credit callback as a
synced manual workout or StrongLifts session.
