Build a 99 OVR squad. Show the math.

Every roster update. The hour it ships.
SDS publishes roster updates on a recurring cadence. 7th Inning polls the SDS roster-update API on the hour, captures every OVR change as soon as the next poll catches it, and writes per-card deltas with old → new. Confirmed-only — no prediction engine.
- Confirmed changes only · no rumor or prediction
- Per-card OVR delta with old → new
- Optional desktop notifications when a new update lands
