Every claim — pointable to a live artefact.

KYE Protocol publishes its own evidence under the same discipline it asks of every adopter: signed, replayable, machine-verifiable from public keys alone. This page is the index. Every claim below links to a live receipt, a per-framework attestation, an open verifier, or a constitution lock.

Security posture

Every security claim → an implementation artefact.

  • Tenant isolation — D1 per-tenant database + R2 per-tenant bucket + KV per-tenant namespace. Cross-tenant traversal is structurally impossible at the binding layer.
  • Authentication — OIDC (Clerk by default; any standard provider supported). Per-request authorisation via Purpose Permission; no ambient runtime.
  • Evidence signing — EdDSA over canonical JSON (RFC 8785 / JCS). Customer-held private keys; KYE sees only the published JWKS.
  • Key rotation — 90-day default; KID-rotatable without breaking in-flight verification (previous-key window).
  • Audit logging — WORM-enforced at the D1 layer + Object-Lock-enforced at the R2 layer. Append-only by structure, not by policy.
  • Rate limiting — per-tenant + per-IP + per-action-class. Rate-cap exceeded emits a typed event into the audit chain.
  • Security headers — HSTS, CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy. Verified on every deploy.
  • Data residency — deploy to the customer's region; sovereign-cloud + BYOC supported. See sovereign-AI pages →
Responsible disclosure
