Find a node of the twin to read its latest observed measures. Once a node is open, set a date to read them as they stood then.
Each layer has its own page: bodies, posts, places, money, events
Each body also has its own page that reads its seat, posts and budget lines as of a chosen day.
Observation layers read: brain food, brain hazard, brain health, brain prescribe services, brain services, bulkbd worldpop upazila year, media places, prices market, prices medicine
No observed measure: no observation in brain_food, prices_market, prices_medicine has this object as its subject, and no snapshot layer (brain_hazard, brain_health, brain_prescribe_services, brain_services, bulkbd_worldpop_upazila_year, media_places) has a row for it (place codes: the registry prints '1061', not a BBS code; not repaired from BBS: no level-4 row of BBS district 10 in the saved geocode PDF matches this name in English or Bengali with both readers agreeing).

Basis: latest observation of each series (measure x qualifier) with observed_on <= as_of; nothing is interpolated. observed_on_basis says whether the source printed the date or it is the fetch date. “published” is what this body publishes, not measures of it. A Place also takes the feed rows keyed to its BBS code (“via”), and the snapshot measures (“snapshot” true) of the layers in “snapshots”: one table row per measure, never summed across rows or sources, never rolled up from upazilas. A year in observed_on counts from its first day; an undated snapshot is served without a date and excluded under as_of (“excluded” says why). Every measure carries its own validation label (“validation”, “validation_basis”); the route's label is the weakest of them.DESCRIPTIVE-SOURCEDno measure served; the numbers are counts of sourced rows
