Provenance first, in plain language
No estimate, no black box. Every field names its source and shows exactly one of four honest states — so a buyer, a bank, or a broker sees at a glance what is established and what is not.
Every field shows one of four states
Confirmed in an official Swiss register. Direct source.
Register queried; nothing on this parcel. The absence is documented.
Derived from a model or an API: real, but not directly from the register. Please verify.
Hit an edge case. Stated honestly at the boundary, never silently discarded.

Frequently asked questions
What does alpflo do?
alpflo resolves a Swiss address down to the parcel and, before a purchase, compiles a source-checked brief — in plain language, with proof of provenance on every field.
What do the four states mean?
Every field shows exactly one of four honest states: "On record" (confirmed in an official Swiss register), "None recorded" (register queried, nothing on this parcel — the absence is documented), "Modelled" (derived from a model or an API, please verify) and "Could not resolve" (an edge case, stated honestly rather than silently discarded).
Which fields does a brief cover?
Among others: building (GWR/EGID), building zone, public-transport quality (ARE), contaminated sites, and ÖREB restrictions. Each row carries its source and its state — presented as what the register states, not as guaranteed truth.
