Report whether the queried address components correspond exactly to an entry in the official Swiss directory of building addresses (swisstopo) snapshot BUMIT holds, preserving the source status (planned / real / outdated), the separate ADR_OFFICIAL boolean and the federal identifiers ADR_EGAID, BDG_EGID, ADR_EDID, STR_ESID and COM_FOSNR independently and verbatim. Matching is deterministic exact equality on normalized street, house number, postcode and locality; normalization is formatting only and no fuzzy, edit-distance, scored, embedding, LLM, guessed or nearest-geographic matching exists. Results are OFFICIAL_ADDRESS / PLANNED_ADDRESS / OUTDATED_ADDRESS / NOT_FOUND / MULTIPLE_MATCHES / UNKNOWN from an explicitly versioned mapping; an unknown or future source status yields UNKNOWN. OFFICIAL_ADDRESS establishes correspondence with the official directory only: it never means a company is registered, domiciled or operating at the address, that mail is deliverable there, that any company is active, or that a transaction is safe, and no company register address is compared. NOT_FOUND is emitted only after a deterministic lookup against a usable, sufficiently current dataset and never means the address does not exist; MULTIPLE_MATCHES retains every match and resolves none. Live retrieval is not implemented and this deployment runs on synthetic fixtures.
