Summary

1 distinct market moments for the away side, fused from 3 raw per-provider trend chains and 40 1-minute market blocks.
22% of blocks tracked a real score/lead change, 33% coincided with a real high-drama play with no score change, 0% moved against the game, and the rest (45%) drifted with no notable event to compare against.
96% of this game's 99 scored plays (95 of them) had their base-runner state read directly from ESPN's structural data, not inferred from text — every other row in the game (pitches, at-bat markers) correctly inherits that same state rather than needing its own read. 4 scored play(s) had no readable base state from either source (a genuine ESPN coverage gap).
