Audit Frozen vs Completed NAIL Context

Build the retrospective allocation audit for NAIL-RAPM v1.0:

uv run nba-audit-nail-context-stability

The default audit scores every observed regular-season stint in 2023-24 through 2025-26 twice: once with the context state available before the target season, and once with the completed target-season state.

Both scores use the same strictly lagged player profile. Actual target-season lineups and possessions are used only to aggregate those scores into observed lineup and player-exposure descriptions.

Use a narrower range or different display thresholds when needed:

uv run nba-audit-nail-context-stability \
  --seasons 2025-26 \
  --minimum-lineup-possessions 250 \
  --minimum-player-possessions 500

The artifact stores coefficient_stability.parquet, stint_nale_stability.parquet, lineup_nale_stability.parquet, player_nale_stability.parquet, and summary.parquet. See Frozen vs Completed NALE Stability for the published interpretation.
