What Exactly Was Filed?
A useful retained record should identify the filing type, period, exact revision, supporting references and submission state—while keeping authority acceptance separate.
The bounded UD model
Existing tax software and authority systems continue calculation, validation, transmission and acceptance. UDR records a changing human-readable record; UDS preserves an exact final state; BrowserCarrier provides offline-readable delivery; amendment begins new lineage.
Claims boundary
Integrity does not prove identity, filing acceptance, tax correctness, legal sufficiency, compliance, admissibility or freedom from audit or penalties.
