Read the record the day it appears
City open-data portals publish building permits daily, and council agenda systems publish land-use cases as soon as they are scheduled. Both are official government APIs, not scraped pages. Each metro has its own schema, so every field is mapped onto one canonical record before anything downstream sees it.
Freshness is measured rather than assumed. A dataset with nothing newer than 21 days is treated as abandoned, of seven candidate city datasets evaluated for this product, two had silently stopped updating years earlier while still serving hundreds of thousands of rows.
