Auto-note //Sitting below zero-gamma (32.50) — dealer hedging chases moves below it. The 35.00 call wall is the nearest-expiry ceiling heuristic; 30.00 is the floor. Options price ±6.3% into Sep 18. Dark-pool short volume at 51% and above vs its 20-day. The falling-knife screen has it turned after a 50% sell-off.

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