Auto-note // The 60.00 call wall is the nearest-expiry ceiling heuristic; 65.00 is the floor. Options price ±6.3% into Sep 18. Dark-pool short volume at 38% and easing vs its 20-day.

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