SME payment authority: pre-execution demonstrator

sme payments · agentic finance · authority before the rail An AI payment assistant prepares supplier payments for a synthetic Armenian SME. Resolve each instruction against the live decision endpoint before the synthetic rail: the IoDE core denial (threshold exceeded, bank details changed, approval covers the old payee, execution grant expired), plus the ALLOW and REQUIRE_APPROVAL paths, each sealed as an Evidence Pack™ you replay from published keys. 6 instructions 4 conditions 1 synthetic rail

AI SRE rollback authority

sre · devops · production action authority An AI SRE agent proposes a production rollback. Walk the action-authority check, delegation resolution, §36 two-person sign-off on the irreversible change, and the sealed Evidence Pack™ + Replay-Proof™. Autoheal finds the fix; KYE™ proves the fix had authority. 4 mitigations 4 gates 2 refused

Consumer chatbot authority

conversational AI · US state chatbot laws A companion chatbot at Lumen Companion Inc under the US state AI-chatbot laws (jurisdiction=California).

telecom · customer consent · live PDP

Telecom Consent Authority

telecom · customer consent · live PDP Pick a telecom-consent scenario and run it live against the sandbox PDP. Verify-consent is admitted, an irreversible line-disconnect is held for approval, and an agent self-escalation is denied — each with a real decision id, replay seed, and sealed Evidence Pack. 3 scenarios 3 outcomes live decide

Collision Marketplace Authority

auto-parts marketplace · cross-vendor fulfilment · live PDP Pick a collision / auto-parts marketplace scenario and run it live against the sandbox PDP. A listing provenance check is admitted, an irreversible cross-vendor parts-order release is held for approval (registered but unauthorised), and an agent self-escalation to pricing admin is denied — each with a real decision id, replay seed, and sealed Evidence Pack. 3 scenarios 3 outcomes live decide

live endpoint

MCP playground

live endpoint Connect from Claude Desktop, Cursor, or Cline. The sandbox exposes a live Model Context Protocol endpoint at mcp.sandbox.kyeprotocol.com with all 12 KYE™ tools mounted.

interactive

KYE™ Reporting Engine™

interactive Per-framework compliance reports. Signed kye.report.v1 envelope, replayable offline from the per-tenant public keys alone. Sub-engine of the Evidence Engine. Mechanism is part of the patent track and is not disclosed in this repository.

What you can do here

One sentence. Plain words. No jargon.

Inspect Evidence Packs

Every observed action is bound to a signed Evidence Pack. Open one to see the authority chain, scope check, drift score, and transparency-log sequence.

Reproduce a decision

Take any fixture action, modify its context (raise the risk score, flip external_export to true), see the verdict change live.

Bring it to your CISO

Every artefact is shareable. Take a screenshot, link to the scenario, or follow Apply for pilot → to bring KYE™ to your real AI-agent traffic.
