United Kingdom

# Runtime authority for sovereign UK AI.

When a UK regulator, a clinical-AI panel, or a financial-services audit asks _who or what acted, on whose behalf, under what authority, inside what scope, in what state, with what decision and evidence_ — KYE Protocol™ answers from a record that existed at the moment of action. Not reconstructed after the audit, not assembled by counsel, not stored in a vendor's logs. Sealed at decision time. Verifiable from the customer's own JWKS.

UK AI Opportunities Action Plan · AISI · DSIT

## The UK is moving from principles to runtime accountability.

The UK's pro-innovation AI framework (DSIT 2023 White Paper), the AI Opportunities Action Plan, the AI Safety Institute, FCA + PRA model-risk discipline, MHRA's SaMD & AI Change Program, NHS DSPT and the Cabinet Office Algorithmic Transparency Recording Standard are converging on the same expectation: AI systems must **prove** their authority at runtime, not declare it in a policy document.

KYE Protocol™ is the runtime authority and evidence layer that lets a UK organisation answer the regulator's first question — _who or what acted_ — with a signed, replayable, machine-verifiable record. No vendor-lock-in on the evidence. The verifier is open; the customer holds the keys.

UK frameworks mapped to KYE™ ™

## Per-requirement bijection — not a checklist on a slide.

For each UK framework below, every substantive requirement is bijection-mapped to the actual KYE™ artefact that enforces it (schema, engine, agent, worker, PDP, evidence pack, audit event). Click a card to open the per-requirement map. The bijection gate fails the build if a citation drifts.

All UK framework cards above link to per-requirement bijection maps generated from the canonical coverage registry. The framework-coverage-bijection gate fails any merge where a citation drifts — the maps cannot lie about which KYE™ artefact enforces which requirement.

UK regulated sectors

## Where UK AI runtime authority matters first.

### UK financial services

FCA Consumer Duty + PRA model-risk discipline + FCA AI Live Testing. Every AI-assisted decision that touches a customer outcome needs a defensible authority chain. KYE™ provides the runtime evidence the FCA expects under SYSC and the PRA expects under SS1/23.

[NHS & clinical AI NHS Data Security and Protection Toolkit + MHRA SaMD + DCB 0129 / 0160 clinical-safety-case discipline + HAARF clinical agent oversight. KYE™ binds the authority chain at recommendation time so the clinical-safety case is contemporaneous, not reconstructed. See clinical AI →](https://kyeprotocol.com/clinical-ai/)

### Public sector

Cabinet Office Algorithmic Transparency Recording Standard (ATRS) + Data (Use and Access) Act 2025 + GDS service-standard accountability. KYE™ produces the ATRS-aligned signed records straight from the runtime decision — not from a quarterly catalogue refresh.

### Critical national infrastructure

NIS Regulations 2018 (post-Brexit) + NCSC CAF + critical-supplier obligations. KYE™ gives operators authority-attenuation, signed revocation and offline-verifiable evidence packs that survive a third-party-supplier audit.

UK-sovereign deployment

## UK data, UK keys, UK control.

KYE Protocol™ deploys to the customer's own Cloudflare account with UK-aligned data-locality (D1 + R2 + KV pinned to the customer's region), customer-held signing keys (BYOK / customer KMS), and an offline-verifiable evidence chain that doesn't depend on a vendor server staying up.

- **Data residency** — deploy to UK-region Cloudflare resources; configurable per-tenant.
- **Customer KMS** — signing keys live in the customer's HSM / KMS; KYE™ never has access to the private key material.
- **Open verifier** — any third party (auditor, regulator, dispute panel) can replay an Evidence Pack™ using only the published JWKS. No vendor dependency in the audit path.
- **UK GDPR alignment** — PII is referenced by URN, not embedded; UK records can stay UK; right-to-erasure is a first-class lifecycle state.
- **Apache 2.0 schemas + vocabulary** — the contracts the customer relies on are open. The patent-track runtime mechanism is paid; the proof formats are not.

UK pilot

## Start in shadow mode. Generate evidence before enforcing controls.

UK pilots run in shadow mode first — KYE™ observes the delegated-action chain and produces signed Evidence Packs™ without blocking any production decision. After the pre-agreed evaluation window, the customer promotes specific Guards from shadow to enforce, one at a time, via a signed Adoption Stage transition. Rollbacks are first-class.

1. **Identify the delegated-action pathway** — one AI-assisted workflow where a regulator's first-question audit would be costly.
2. **Bind KYE™ read-only** — observe the actor, principal, authority, purpose, scope and state at decision time. No IAM replacement, no production blocking.
3. **Identify authority gaps** — signed reports surface where the chain breaks (missing grant, out-of-scope action, stale delegation, etc).
4. **Produce signed Evidence Packs™** — per governed action, replayable offline from the customer's JWKS.
5. **Promote selected Guards to enforce** — one narrow class of action at a time, on the customer's schedule, with signed adoption-stage transitions and first-class rollback.
