Interval-censoring. Observation window from 2026-08-01 to 2026-09-11, with 40 dated observations. A state transition inside an unobserved span is dated to that interval, not to a single day. The dependent count is the value carried with the latest census (2026-09-11). Absence of an observation on a date is recorded as not observed, never as a state.
