Time Series & Form (Sports)

Overview

Sports performance is ordered in time. This skill builds form features and simple trajectory forecasts that are legal at decision time T:

• rolling means
• expanding rates
• EWMA / decay
• rest gaps
• regime flags

The bundled helper constructs shifted EWMA features from a user-owned event table, and the comparison helper evaluates already-computed feature sets.

Non-negotiable: shift (or as-of) so the current game is never inside the feature.
