AMC Summit 16

Preview dates are observation dates in UTC, independently of the show-date filter. One latest observation per showtime per day. Counts reflect sampled coverage, not a complete daily AMC inventory; a decline does not prove cancellations.

Bounded preview coverage: partial. 144 of 156 retained files loaded; 12 skipped and 3 invalid records. These limits apply to every metric below. This is not the exhaustive history index or AMC's full schedule.
