Circuit-breaker log (7 checks)
  • Rule 2 check passed: market line -152 within the day-game juice cap (-170; night -180, day -170, day = first pitch before 17:00 venue-local).
  • Rule 8 check passed: raw model 49.5% vs de-vigged market 59.4%: 9.9-point divergence within the 12-point cap (blended to 54.5% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is -5.9 pts (minimum 2). No allocation; a good side at a bad price is a bad bet.
  • Rule 4 flag: Jackson Kent under 60 IP this deep in the season (limited workload / possible IL return). Volume freeze: confidence downgraded one tier.

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.

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