Historical Player Prop Odds

The Prop Summary file has one row per player prop per game: the line when we first saw it, the close, the stat from the box score, and over, under, push or void. Prop history starts August 4, 2026, and the free week is September 15 to 21, 2026.

1. The same player_id on every player file, so props join to game logs with no name matching.
2. A void says why it has no result.
3. Fixed checkpoints in the props file: first seen, six hours out, one hour out and the close.
