Structured from the register

Reference, address, type, status, decision and dates come straight from the council. A field the council does not publish stays empty; we never fill it in.

Every change recorded

Each crawl diffs the record and stores what changed, old and new, with a timestamp. The API exposes the same history as a cursor feed.

Extracted fields show their source

Where a model reads a description or a decision notice, every value carries the quoted passage it rests on and a confidence. Quotes that cannot be found in the source are flagged.
