1 · Threshold exceeded
The amount is at or above the assistant’s delegated payment threshold and no recorded approval names this instruction. Held: payment_threshold_approval_required.
KYE™ SME Payment Authority Pack™
A payment rail decides whether a payment can settle. It cannot tell whether the agent that requested it was entitled to. KYE™ SME Payment Authority Pack™ sits between an AI payment assistant and the rail and resolves, at the moment of each instruction, whether this agent under this delegation at this moment may cause this payment: against the delegated threshold, the verified payee, the approval the approver actually saw, and a live execution grant. The decision is sealed first; an unauthorised instruction never reaches the rail.

What it is
The synthetic workflow
The core demonstrator scenario
The most persuasive demonstration is not a routine allowed payment but one the rail would happily process. Four conditions, each a rule in the pack, each with its own reason code on the sealed Decision Map™:
The amount is at or above the assistant’s delegated payment threshold and no recorded approval names this instruction. Held: payment_threshold_approval_required.
The payee account on the instruction differs from the supplier’s last verified record. This is the invoice-redirection pattern a rail cannot see. Denied: supplier_bank_details_changed.
An approval exists, but it was recorded before the payee changed. The approver consented to the verified payee, not this one. Denied: approval_superseded_by_payee_change.
The time-bounded authority to submit had lapsed when the instruction reached the gate. Absent authority denies however well-formed the instruction is. Denied: authority_expired.
All four together: DENY before rail submission, with all four reason codes on the record. Run it against the live decision endpoint, then replay the Evidence Pack™ yourself.
Honest scope
KYE™ does not settle payments, hold funds, verify a bank account, or operate a rail. Those remain the functions of the SME’s bank, its payment provider and its own finance controls. What KYE™ governs is the moment an AI agent acts: whether the instruction is admissible, under whose delegation, within which limits, covered by which approval, under which live grant, and with what evidence on the record. That maps to the duties your oversight already sets: strong customer authentication and payee verification under PSD2, operational control of AI systems within declared boundaries under ISO/IEC 42001, accountable and verifiable AI action under the NIST AI Risk Management Framework, data minimisation under the GDPR, and supplier information-security controls under ISO/IEC 27001 — each consumed as a governed authority-and-evidence boundary, never a claim that KYE™ replaces them.
The founding instance is a zero-budget applied-research pilot with a digital-economy institute in Armenia, run on synthetic data only: synthetic invoices, suppliers, purchase orders and instructions; no real SME records, no real customer data, no live bank integration, no real payment execution. No funding, procurement, regulatory approval or endorsement by any central bank, ministry or public body is requested or implied. Production-data admission is a separate, governed second phase with its own obligations: tenant isolation, write-once audit with framework-justified retention, a data-subject access and withdrawal route, a live rail only after authority-before-rail is proven, incident and kill-switch duties, and a monthly joint review.
The pilot
For an SME finance team, an open-finance platform, a payment provider or an accounting-software vendor putting an AI assistant on payment operations. Eight-week engagement; synthetic data only.
