Why a Retained Tax Record Should Remain Independently Verifiable
A recipient should be able to test whether the retained final bytes remain intact without needing the originating software to render or compare them.
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.
