Circuit-breaker log (7 checks)
  • Rule 2 check passed: market line -156 within the night-game juice cap (-180; night -180, day -170, day = first pitch before 17:00 venue-local).
  • Rule 8 check passed: raw model 53.3% vs de-vigged market 60.0%: 6.7-point divergence within the 12-point cap (blended to 56.6% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -4.3 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 check passed: both starters carry full-season workloads.
  • Rule 6 check passed: away 14-day wOBA 0.347 vs league 0.315 (gap -0.032, threshold 0.035).
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 71°F at first pitch: run environment x1.003. Applied to the paper totals pick; the staked board ignores weather entirely.

The close is the last pre-first-pitch capture. Movement toward a side after we post is the fastest honest read on pick quality — see the CLV column on the ledger.

✅ Watch pick (market-proving, paper, 0u staked): Over 8 (-110, BetRivers) — WIN (+0.91u paper).

No stake rode on this game. The lean and its failed gates above are the whole position: passing is a position too.
