Record definition and data status

Career records use countable coach-season rows. Zero-game placeholders are excluded from aggregates until a completed-game fallback can verify the record.

Completed-game fallback uses scored games joined by coach, team, and season; advanced ratings are left blank when the season summary has not supplied them.

Latest completed coached game in this dataset: Nov 23, 2007. Current and future zero-game placeholders are kept visible but excluded from headline records.
