Provenance: a lease record that can show its work

Why it surfaced

This is unusually concrete product thinking: every proposed fact points to a document page, corrections are preserved in an append-only history, and deadlines recalculate when an amendment changes the underlying record. A public sample portfolio lets visitors walk through three properties and twelve leases without a sales call.

Provenance turns commercial leases and amendments into cited, verifiable facts, then derives obligations and deadlines from those records.
