nx_doc_envelope.nx -- LEGAL RUNG D2: the e-signature ENVELOPE workflow. module: nishi-core.legal.doc_envelope capability: LEGAL_ESIGN_ENVELOPE The "DocuSign but better" WORKFLOW core. It orchestrates one document through create -> send -> sign (per recipient, in routing order) -> complete, binding the three already-GREEN legal organs into one client-facing flow: D0 nx_legal_compliance -- classify the document + pick its legal regime at CREATE; REFUSE to route a void instrument into the e-sign flow at SEND (never-route-a-void-instrument). D5 nx_doc_seal -- each signer's signature is a REAL RFC-8032 Ed25519 seal; SIGN verifies it; an envelope can only COMPLETE when every required signer has a VERIFIED, non-refused, VALID-verdict seal (all-signers-or-not-complete). D1 nx_doc_vault -- (gate-composed) the completed, sealed version is attached to the per-tenant additive vault. THE s-class-exceed property, carried LIVE through the workflow (a generic e-sign product lacks every one of these): * a will / codicil / testamentary trust in a NON-e-wills jurisdiction can NEVER be sent for e-signature -- it would produce a legally VOID instrument (UETA 3(b) / ESIGN 7003(a)). The refusal is at the workflow boundary (SEND), not merely at the crypto. This is the legal analog of Rule 26. * routing order is enforced -- recipient N+1 cannot sign before recipient N. * a forged or tampered signature can never complete an envelope. * decline / void retain full history (Rule 13 additive-only). * we do NOT over-refuse: a properly-executed e-will (in an e-wills state) routes through the stricter regime and completes. Representation: caller-allocated flat i64 record arrays (substrate scale- agnostic, no internal allocation), mirroring nx_doc_vault. Pure logic core -> the gate is self-contained (no socket, no fork). Composes: nx_legal_compliance (D0 classify+regime+verdict), nx_doc_seal (D5 NxSeal + verify). Distinct from nx_doc_seal because: that produces ONE signature; this is the multi-recipient lifecycle + status + audit around it. license_tier: ORIGINAL lineage_id: nishi_doc_envelope_d2
