Product
Siboga stores the raw public record, parses it, resolves the parcel and the owner, keeps the history, and distributes pinned snapshots. It is built for teams that must show their work.
Operator lead lists for real-estate investors are served by a separately licensed product. Siboga is the warehouse and the institutional channel.

How a record is built
The response body as the source gave it, stored write once with request shape, response headers, fetch time, and SHA-256. The normalized layer must be reconstructible from raw alone.
Typed, deduplicated rows with a reference back to the raw object. Each event is matched to a parcel by parcel ID first, coordinates second, and address last, and the match method and confidence are stored on the row.
Joins, flags, and cross-signal chains computed from normalized data. Always recomputable, never hand edited. A wrong derived value is fixed in the derivation, not in the row.
