// WHAT THIS PAGE WILL DO
- →PECOTA-style player similarity over a 38-feature vector.
- →Z-scored weighted Euclidean distance, every contribution explainable.
- →Hard bat-hand filter by default; Edge tier unlocks override.
- →Linear time decay over 4 historical seasons (1.0 / 0.7 / 0.4 / 0.2).
- →Hypothetical batter builder for Edge tier (project a custom player profile).
We don't ship features that aren't backed by methodology. This page goes live with full functionality — never a half-built version.
