ApproveChainWitness

The research confirms an enterprise approval product, general audit platforms, signing and policy primitives, and no reviewed federal delegation-graph product. One of two referenced interfaces remains unverified and no structural incumbent copying cost is evidenced. The proposed public-sector wedge is plausible but must not be presented as an accepted federal standard before an agency and counsel validate it.

A cryptographic signature proves control of a credential under a system; it does not prove the signer had appointment, funds, warrant, delegation, subject-matter authority, current role, absence of conflict, or legal capacity for the action. Delegations can be conditional, revocable, time-bound, amount-bound, program-specific, and affected by succession, emergency rules, separation of duties, and native system state.

ApproveChainWitness should preserve the authoritative source of delegation, version, effective dates, limits, prerequisites, exceptions, reviewer, and revocation. A failed check blocks only where the agency has explicitly authorized the control. Dossiers can use structured formats after validation, but no export is automatically FAR-, DCAA-, GAO-, protest-, discovery-, CMMC-, or OSCAL-defensible.

Government procurement offices and public-sector contractors that need source-linked delegation, approval, exception, and correction evidence around existing systems of record.
