Circuit-breaker log (8 checks)
  • Rule 2 check passed: market line +108 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 55.5% vs de-vigged market 47.8%: 7.7-point divergence within the 12-point cap (blended to 51.6% at MODEL_WEIGHT=0.5).
  • Rule 4 check passed: both starters carry full-season workloads.
  • Rule 6 flag: away 14-day wOBA 0.279 trails league 0.317 by 0.037 (threshold 0.035). 8% run tax applied to the away run rate.
  • Rules 3/5 (velocity/spin telemetry): manual review required: Statcast feed not wired.
  • Weather (totals paper track ONLY): 82°F at first pitch: run environment x1.048. Applied to the paper totals pick; the staked board ignores weather entirely.
  • ✳ Best of Board: the gates left no held plays today, so this is the model's top remaining lean — 0 units, NOT staked, published for transparency. The checks above show exactly which gate it failed.
  • 🎯 Daily Pick (v0.15): the slate's top-ranked eligible candidate (score 0.790) under the always-on strategy's lower, precommitted bar. 0u through the proving window (ends 2026-09-08); separate public ledger, never mixed with the Qualified record.

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.
