 "_method": "Each domain has a known launch date and one observation date, so age at observation is known. This is the epidemiological cross-sectional estimate, not a longitudinal one.",
 "_assumption": "⛔ LOAD-BEARING: launch cohorts are assumed EXCHANGEABLE — a Jan 2025 launch comparable to a Jun 2026 launch except for exposure time. Show HN volume grew sharply across this window, so later cohorts are larger and may differ in kind. If the population changed, this curve confounds AGE with COHORT. A longitudinal round 2 is what confirms or kills it.",
