Release Notes

Games: 570 game pages (2024–2025) — win-probability paths, validated drive ledgers with expected-points context, largest swings, source receipts on every page.
Teams: 64 team-season pages — situational offense/defense profiles, drive economics, game logs, and a research-labeled offensive-line continuity panel (a unit descriptor, never a player rating).
Players: 1,015 player fact pages — opportunity ledgers (passing/rushing/receiving/kicking/punting), participation snap counts, per-game logs. Conventional facts only; every page states plainly that no player ratings exist yet. Zero unmatched identities across both seasons.
EP/WP tournament v1 concluded: RETAIN_BASELINE. Under frozen, result-blind gates on 339,109 plays, no independent arm beat replaying the source model — so pages display source EP/WP with attribution, and independent arms remain research. The NULL result is published, not hidden.

First public shell. No player ratings exist yet, and none will appear until they pass result-blind evidence gates.
Source and rights system live: 87 immutable captures across play-by-play (2016–2025), participation (2016–2025), FTN charting (2022–2025), rosters, snap counts, NGS aggregates (2016–2024), schedules, players, officials, contracts.
Canonical play/drive pipeline with a conservation suite: all ten seasons PASS — ~484,000 plays, zero fatal, zero error findings; warnings recorded honestly (clock corrections; NGS-era participation rows listing more than 11 players).
Metric registry published with the full family at honest concept/scaffold status.
