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 9.5 (+103, LowVig.ag) — WIN (+1.03u paper).

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