The GEFS 35-day virtual update currently starts at 03:45 UTC, after the full extension was already available on 26 of 29 surveyed days. Start it at 02:15 UTC so the pod is polling before the previous cycle's final overnight dump, and extend its deadline to 8h30m to retain coverage of the new cycle's short leads and morning extension members.

Polling ends at 10:38 UTC with the existing seven-minute validation grace, covering the measured morning wave through 10:06 UTC. The init-relative CheckCurrentData allowance remains 3h50m; validation monitoring derives its timing from the new deadline, and the next-fire check still allows the validation retry. Update the arrival-pattern comment, timing tests, and documentation of latency during inactive gaps. Correct the recovery comment to describe one missed daily fire; the 72-hour update window is unchanged.

Validation: 210 affected dataset/shared tests passed, including the source-backed integration and freshness-deadline checks; Ruff format/check and ty passed. The change targets prompt full-set completion; it does not guarantee sub-minute visibility for every individual file.
