Case contract

Corrections are [timestamp seconds, per-day sequence, stat, corrected absolute value]. Apply corrections whose UTC day (timestamp // 86400) is on or before the deadline day, ordered by timestamp then sequence; each replaces the stat value (a later correction wins, a stat missing from the base line is added). Points are the weighted sum over the weight table using corrected stats. Return stats, points and the count of corrections applied.

Why this case matters

Official stat corrections change settled fantasy results days later; their ordering and cutoff rules must be exact.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
regression: ordering by per-day sequence	`{"applied": 4, "points": 97, "stats": {"rec": 5, "rush_yds": 72, "td": 0}}`	`{"applied": 4, "points": 50, "stats": {"rec": 5, "rush_yds": 25, "td": 0}}`	Failed
