Project/owner/date: Required presence/zone/coordinate/transition outcome: Required update and stale-data behavior: Exact tag, receiver, engine and application versions: For EACH boundary (tag/receiver, receiver/engine, engine/application): Standard number, part, edition, options and current catalog status: Vendor protocol/API version and supported product pair: Report/certificate scope and document reference: Identifier, units, coordinate frame, floor and timestamp definitions: Authentication, errors and unsupported-field behavior: Interface owner and upgrade-support policy: Test cases: known tag at known location; planned movement; unknown tag; reassigned tag; stale/delayed observation; missing update; supported restart. Case / expected / actual / evidence / pass-fail-pending / owner: Fictional units check: engine x=12.5 metres; application expects centimetres. Expected converted value is 1250 centimetres. A successful message exchange alone does not validate the coordinate meaning. Observation time versus receipt time verified: Asset identity lifecycle and mapping export verified: Location accuracy pilot reference (separate from interface compatibility): Remaining exceptions, acceptance owner and retest triggers: Public standards scope and related pilot guidance are in the companion.
