Auto-note //Sitting below zero-gamma (25.25) — dealer hedging chases moves below it. The 25.00 call wall is the nearest-expiry ceiling heuristic; 25.00 is the floor. Options price ±3.2% into Sep 18. Dark-pool short volume at 25% and easing vs its 20-day. The falling-knife screen has it turned after a 34% sell-off.

Composed from the nightly pipelines — every panel degrades independently when its dataset is missing. Heuristics labeled as heuristics; not investment advice.
