Structured Filing Data and Trustworthy Documents Solve Different Problems
Schemas and APIs support authority processing; a trustworthy portable document also needs human presentation, identity, lineage, finality and retained-copy verification.
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.
