  • Rule 8 check passed: raw model 52.5% vs de-vigged market 62.0%: 9.4-point divergence within the 12-point cap (blended to 40.3% at MODEL_WEIGHT=0.5).

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 7.5 (-113, LowVig.ag) — LOSS (-1.00u paper).

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