Replay

Replay takes a captured real day, the load curve as it unfolded, and runs the exact production model over it, showing what WattMarkets would have said at each hour. The archive includes the famous June 30, 2024 Sunday peak that day-of-week models missed. Golden replay days are frozen in CI: a model change that flips one from HIT to MISS cannot ship without an explicit version bump.
