Notes:
- First complete 100K full-pipeline run covering all three outcome
  tables: game_outcome_context, play_by_play, season_outcome_context.
  Total wall 2h 58m, cost ~$27.
- Memory: 46.6 GB peak vs 46.8 GB on the no-season 100K run —
  essentially unchanged. The refactor capped the season accumulator's
  footprint to ~1.3 GB regardless of world count (was projecting 270 GB
  on the original nested-dict implementation, which OOM'd at 100K).
- Sim phase +48% vs no-season (1,462s → 2,169s). Cause: season
  accumulator AccumulateGame + FinalizeWorld calls run under a global
  lock because the shared instance's internal dictionaries aren't
  thread-safe. 288 games × 100K worlds = 28.8M locked calls. A future
  follow-up could use per-worker accumulators + a merge step (same
  pattern the game accumulator uses), but 12 min of added wall time
  at 100K is well within budget for this gate.
- Row counts: 244,800 OC ✓ • 4,198,981,505 PBP ✓ (matches 10K ×10
  within stochastic variance) • 1,728 season ✓.
- Season write: 22.90s for 1,728 rows with 100,000-element arrays
  each. Scales roughly linearly from the 10K run's 7.08s.
