Identity and joins
Use exact BBL and one exact ordinary primary row per property/tax year; easement and REUC rows never silently replace it.
History
Retain accepted annual source archives and selected-field histories; rebuild from the exact official layout on source correction.
If the source fails
Suppress only the assessment block and preserve prior private evidence as historical, not current.
Storage boundary
Keep content-addressed archives and selected histories on the tower under the private research boundary; publish no values.
What must be resolved before broader use
An exact selected-field adapter must use or prove equivalence to Open Data 8y4t-faws, pass fresh completeness and identity gates, and retain the literal no-tax-advice wording before any value is displayed.
