Circuit-breaker log (9 checks)
  • Rule 2 check passed: market line +104 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 53.2% vs de-vigged market 48.5%: 4.7-point divergence within the 12-point cap (blended to 50.9% at MODEL_WEIGHT=0.5).
  • Edge gate: model edge vs offered price is +1.9 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 0.329 vs league 0.314 (gap -0.015, threshold 0.035).
  • 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 x1.047. 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 0.769) 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.

✅ Watch pick (market-proving, paper, 0u staked): Under 8 (-104, FanDuel) — WIN (+0.96u paper).

✅ Watch pick (edge-band, paper, 0u staked): Detroit Tigers ML (+104, FanDuel) — WIN (+1.04u paper).

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