> The evidence layer that makes legal accountability for AI agents possible. Subpoena response in 48h. Agent-as-contracting-party contracts enforceable. UNCITRAL MLES + FRE 901 + GDPR Art 22 + EU AI Act Art 13 — all answered by one signed Evidence Pack™.

Legal sector

# The evidence layer that makes legal accountability for AI agents possible.

Today there is no machine-enforceable answer to _“this agent acted on behalf of this principal under this delegation.”_ Disputes settle by deposition. Insurance excludes AI loss. Contracts say _“use commercially reasonable effort”_ because nothing better exists. KYE Protocol™ changes that — every privileged agent action carries a signed Authority Chain™ + Purpose Permission™ + Decision Map™, replayable from public keys alone by counsel, regulator, or arbitrator.

[Apply for the Legal Pack™ pilot](https://kyeprotocol.com/pilot-apply/) [Tier-1 / Custom — talk to the team](https://kyeprotocol.com/pilot-apply/) [See a real dispute pack](https://kyeprotocol.com/stakeholders/example-reports/dispute-resolution/)

**Refusal IS the exhibit.** KYE™ intercepts every AI-agent privileged action at the admissibility layer — out-of-scope actions are refused with a signed envelope counsel can submit as evidence. UNCITRAL MLES Art 6 + FRE 901(b)(9) verifiable offline against the published JWKS.

What it is

## A productised legal-pack workspace + the four primitives a contract needs.

- **Authority Chain™.** Every privileged agent action carries a signed chain back to the named human principal who delegated it. _"Agent X acted under delegation D from Principal P at time T"_ stops being an assertion and becomes a verifiable byte string. Replayable from public keys alone — counsel does not need vendor cooperation.
- **Purpose Permission™, scope, revocation.** The contract clause _"agent may act only for purpose P, scope Q, revocable within Z seconds"_ becomes literal URN-addressable primitives: `kye:purpose-permission:…` + `kye:delegation:…` + `kye:tenant:…`. A court enforces by reference to bytes, not by inferring intent from logs.
- **Evidence Pack™ + Replay-Proof™.** Per-decision signed envelope retrievable by ID: `GET /v1/evidence-packs/{decision_id}`. Ed25519 signature against the issuer's published JWKS — tamper-evident, vendor-cooperation-free, admissible under FRE 901(b)(9), satisfies UNCITRAL MLES Art 6/8 reliability presumption.
- **Multi-regime crosswalk.** The same signed envelope simultaneously answers UNCITRAL MLES + English CPR Pt 31 + US FRE 901 + NY Convention Art V + LCIA / ICC rules + EU AI Act Art 13 + GDPR Art 22 + Brussels I Recast Art 7(2). One artefact, every jurisdiction.

Why this matters now

## Agents are being deployed faster than the law that governs them.

A procurement agent makes a wire transfer to the wrong supplier. A clinical-AI agent recommends a treatment that turns out to be off-label. A customer-service agent commits a refund the company never authorised. Today, the answer to _“was the agent allowed to do that?”_ is a six-month forensic exercise across logs that were never designed to answer it. KYE™ is the first protocol that makes the answer a single API call — `GET /v1/evidence-packs/{decision_id}` — returning a signed envelope a court can verify offline without your cooperation.

Already proven on a regulated-casework adjacent — the legal pattern is identical

## See it working today — KYE™ Estate Planning Authority Console™.

Estate planning is the closest neighbour to dispute-resolution casework: regulated, evidence-bound, every matter ends in an authorised final state with a signed pack a regulator can audit. KYE™ already ships the Estate Planning Authority Console™ end-to-end — deterministic drafting, bounded AI Case Checker, six-state boundary engine (within-adviser-authority / manager-review / solicitor-review / outside-scope / authority-invalid / evidence-insufficient), authority finality, replayable envelopes. The same primitives drive the Legal Pack™.

The Legal Pack™ pilot uses the same governed-workspace shape: signed matter chain, bounded delegated AI, jurisdiction-bound authority, regulator-grade evidence envelope. Where EP draws on SRA + STEP + IHT; legal draws on UNCITRAL + CPR + FRE + LCIA + EU AI Act.

Two worked examples

## From six-month deposition to 48-hour settlement.

[**1. Supplier-payment dispute · settled pre-litigation** Acme Ltd's procurement agent paid €182,400 to Counterparty BV. Counterparty alleged wrong-supplier-impersonation. Acme issued one signed Evidence Pack™ proving the agent acted within its `kye:delegation:…-cfo` authority, on the supplier on file at decision time, to the correct IBAN. Counterparty counsel accepted as conclusive. **Settled in 48h. Zero depositions. Zero discovery cost above retainer.**](https://kyeprotocol.com/stakeholders/example-reports/dispute-resolution/) [**2. Agent-as-contracting-party** A SaaS vendor sells an “AI procurement agent on your behalf.” The vendor contract today says _“commercially reasonable effort”_ because no machine-enforceable concept of agent-scope exists. With KYE™, the contract clause becomes: `kye:purpose-permission:X` + `scope:Y` + `revocable-at:Z` — literal URN-addressable primitives. Insurance carriers (4 active AI E&O policies) recognise the same primitives as in-scope proof of _“Insured Event Demonstration.”_](https://kyeprotocol.com/stakeholders/example-reports/general-counsel/)

Who it is for

## Counsel, GC, litigators, arbitrators, and insurers.

- **General Counsel.** You sign off on AI-agent deployment across procurement, legal-ops, customer service. Today you accept a vendor's _"commercially reasonable effort"_ clause because nothing better exists. KYE™ replaces it with literal URN-addressable scope; refusals are signed exhibits you can submit without vendor cooperation.
- **Disputes / litigation partner.** You spend six months on discovery to answer _"was the agent allowed to do that?"_. KYE™ resolves it in one API call: `GET /v1/evidence-packs/{decision_id}` → signed envelope verifiable offline. Pre-litigation settlement becomes the default outcome.
- **Arbitrator / court-appointed expert.** You evaluate the reliability of electronic evidence under UNCITRAL MLES Art 8 or FRE 901(b)(9). KYE™'s Replay-Proof™ envelope clears the reliability presumption without expert testimony or vendor cross-examination.
- **AI E&O / cyber insurer.** You exclude AI-driven loss because you cannot price what you cannot verify. KYE™ gives the insured a per-incident signed envelope you can use as the _"Insured Event Demonstration."_ 4 active AI E&O carriers already recognise the primitives.
- **Compliance / DPO.** You report on GDPR Art 22 automated-decision compliance. KYE™'s per-decision Evidence Pack™ proves the human-in-the-loop step on every `require_approval` flow — no sampling, no log forensics.

Legal-framework crosswalk

## Every signed Evidence Pack™ simultaneously answers multiple legal regimes.

The same artefact — one signed envelope — satisfies the evidentiary bar across electronic-signature law, civil discovery rules, arbitration enforceability, automated-decision regulation, and AI-transparency obligations. One Evidence Pack™, all jurisdictions.

| Framework | Clause | How Evidence Pack™ answers it |
| --- | --- | --- |
| **UNCITRAL MLES** | Art 6 · Reliable electronic signature | Decision Map™ Ed25519 signature verifiable against published JWKS. |
| **UNCITRAL MLES** | Art 8 · Reliability presumption | Signed bytes + Replay-Proof™ against published JWKS → presumed reliable. |
| **English CPR** | Pt 31 + PD 31B · e-disclosure | Single `decision_id` resolves to full chain; no manual collection or pre-disclosure review. |
| **US Federal Rules of Evidence** | 901(b)(9) · System authentication | Public-key verification satisfies _“process or system that produces an accurate result.”_ |
| **NY Convention** | Art V(1)(b) · Enforceability | Signed evidence reduces “denial of opportunity to present case” risk. |
| **LCIA / ICC Arbitration** | Evidence rules | Signed Evidence Pack™ admitted as conclusive without expert testimony. |
| **EU AI Act** | Art 13 · Transparency obligations | Decision Map™ + Purpose Permission™ satisfy the “interpretable for the user” duty. |
| **GDPR** | Art 22 · Right not to be subject to automated decision | Per-decision Evidence Pack™ proves human-in-the-loop for `require_approval` flows. |
| **Brussels I Recast** | Art 7(2) · Jurisdiction | Decision-time jurisdiction binding supports counterparty's chosen forum. |

The legal primitives KYE™ ships

## What a contract clause looks like with KYE™.

Today, contracts governing agent behaviour are aspirational because the primitives don't exist. KYE™ ships every primitive a clause needs:

- **Authority Chain™** — _“Agent X may act only under a delegation traceable to a named human principal.”_ Enforceable: every action's signed chain is replayable.
- **Purpose Permission™** — _“Agent X may act only for purpose P, with scope Q, attenuable but never broadened.”_ Enforceable: the URN `kye:purpose-permission:…` is the contract term.
- **Scope attenuation** — _“Sub-agent Y inherits a strict subset of X's authority.”_ Enforceable: scope arithmetic is part of the Authority Engine.
- **Revocation** — _“Principal may revoke authority effective within Z seconds.”_ Enforceable: revocation propagation latency is measurable and signed.
- **Evidence Pack™** — _“Every action produces an admissible record.”_ Enforceable: each decision has a signed envelope retrievable by ID.
- **Replay-Proof™** — _“Records are tamper-evident and verifiable without vendor cooperation.”_ Enforceable: anyone with the published JWKS can verify offline.
- **Jurisdiction binding** — _“Agent X operates only within jurisdiction J.”_ Enforceable: signed cross-border-evidence envelope on every cross-border movement.

A contract that cites `kye:purpose-permission:…` + `kye:delegation:…` + `kye:tenant:…` is a contract a court can enforce _by reference to bytes_ — not by inferring intent from vendor logs that may or may not have been preserved.
