Conformance you can replay with public keys alone.
Five tiers, 41 black-box fixtures, 266 control mappings across 13 frameworks. Every claim at every tier is a signed artefact a regulator or auditor can verify offline. The protocol is Apache 2.0; certification is the only commercial layer.
Three pressures, one artefact.
Five tiers, each one a public claim.
- L0Declared — you publish a profile statement. No verification, no listing. The honest baseline; useful for early-stage integrations and roadmaps.
- L1KYE Self-Tested™ — run the 41-fixture conformance pack locally and self-declare. Available today.
- L2KYE Self-Attested™ — signed self-attestation (Ed25519, JWS) bundled with fixture results. Available today; programme verifies the signature.
- L3KYE Conformant™ — programme review of schema + endpoint + behaviour + evidence shape + error codes + edge cases. Programme in development; opens with v1.1.
- L4KYE Certified™ — third-party-audited certification by an approved audit firm; annual revalidation. Programme in development; first audit firms onboarding with v1.1.
Capability-scoped Conformance badges
Within each tier, an implementation can carry capability-scoped marks. Each badge attests to a defined slice of the conformance pack — not the whole thing — so an implementation can grow its claims one capability at a time.
/badges/{badge_id}/verify showing implementation, profile version, test-suite version, issued / expires dates, and revocation status.
Black-box, deterministic, replayable.
The conformance pack is 41 black-box fixtures grouped into seven families. Each fixture takes a signed input, expects a deterministic output, and is replayable offline using the published key set. No fixture depends on hosted infrastructure; conformance is reproducible on a laptop.
- Identity & URN — entity creation, URN parsing, class taxonomy, alias resolution, trust-domain assertions.
- Delegation chain — chain construction, attenuation rules, parent ⊇ child enforcement, SCA-at-the-edge propagation.
- Authority grants — capability binding, scope predicate evaluation, revocation, time-bound expiry.
- State & lifecycle — state transitions, quarantine, suspension, replay, recovery.
- Decision & runtime —
/v1/runtime/authorizecontract, decision codes, constraint emission, latency envelope. - Evidence & audit — append-only chain integrity, evidence-pack composition, OSCAL projection, public-key replay.
- Cascade & recovery — cascade propagation properties (timing assertions only; mechanism is in the patent track).
13 frameworks, one rail.
Conformance projects through the KYE Compliance Mapping Rail™ into 266 named controls across 13 frameworks. The same evidence pack satisfies multiple frameworks; you do not run separate audits for the same artefact.

L4 audits, by firms a regulator already accepts.
L4 audits are run by independent firms approved by the KYE Protocol™ programme. Approval criteria: SOC 2 / ISO 27001 / EU AI Act-notified-body credentials, prior regulated-sector audit experience, and a signed audit-firm agreement that aligns scope, evidence handling, and report format. Audit firms do not pay to be listed; partners and end customers select from the published list.
The approved-audit-firm roster opens with the v1.1 release. Firms interested in joining should contact the programme via the link below.
Cadence + change-notification.
- M1L1 / L2 self-tiers. Re-run fixtures whenever your integration changes; resubmit signed report. No fixed cadence.
- M2L3 KYE Conformant™. Notify the programme on any breaking change. Programme spot-checks 10% of L3 partners per quarter. Listing flagged if checks fail.
- M3L4 KYE Certified™. Annual revalidation by your audit firm. Listing carries the last-revalidation date. Lapsed certifications drop to L3 status until refreshed.
- M4Spec version bumps. Major-version bumps (v1 → v2) require re-certification within 12 months. Minor bumps are additive; no re-cert.
Begin certification.
For most teams, the path is L1 first (run fixtures, find gaps), then L2 (sign + submit), then L3 (programme review). L4 is the destination, not the starting point.
