"""Calendar-driven in-process scheduler. Non-trading days skip EOD fetches.
EOD datasets that failed to publish (e.g. upstream not ready at 15:05)

``eod_retry_start`` and ``eod_retry_cutoff``. Progress is persisted in
``eod_progress`` so a container restart catches up instead of waiting
for the next day, and completed days are never re-fetched.
