Launch autonomous universal sports engine

[Chris-ObtuseAI]

What this delivers

Launches Universal Sports Engine 0.3.0: a deterministic, high-throughput,
multi-league simulation platform with exact replay, bounded recursive calibration,
online expert weighting, drift-aware shadow monitoring, and content-addressed
champion governance.

Why it matters

• Unifies MLB, NBA, WNBA, NCAA MBB, NFL, NCAA Football, and NHL behind a neutral kernel.
• Preserves sport-specific rules and mechanics in isolated league packs.
• Separates fast analytical distributions from interpretable event simulation.
• Makes every autonomous promotion, rejection, weight update, and rollback auditable.
• Fails closed when integrity, calibration, drift, or reproducibility gates fail.

Verified evidence

• Ruff passes.
• Strict MyPy passes.
• All 67 integration and invariant tests pass.
• Release evidence gates pass across all seven leagues.
• The 49-control negative and mechanism suite reports zero failures.
• The 14,000-game stress audit reports zero failures.
• The autonomy audit verifies champion, ledger, shadow-update, and rollback integrity.
• A clean wheel rebuild reproduces the expected package contents.

Evidence boundary

This release verifies mechanics, determinism, replay integrity, autonomy governance,
and measured local throughput. It does not claim real-world predictive supremacy.
That requires licensed point-in-time game, roster, injury, event, and tracking data
plus held-out and prospective validation.
