Release: 2026.10.29-relay-redesign.1 (LIVE_PRODUCTION)
Canonical registry: https://axiomrelay.io/api/v1/capabilities
Canonical Directory: https://axiomrelay.io/api/v1/directory
Registry version: 2026-09-10.registry-5
Registry digest: sha256:823d5caa77543be8182fc372e92933ffeec45c056c6f381ea00a5b52f293d86a
Lifecycle: LIVE_PRODUCTION/LIVE_SANDBOX describe verified reachability for the named surface; PUBLISHED contracts/read models are readable without execution authority; DEPLOYMENT_READY awaits guarded activation; REFERENCE is informational; GATED is unavailable.
Directory ordering is not an evidence-supported performance ranking. It has no first-party boost and ignores subscriptions, ads, fees, sponsorship, and settlement destinations.
Communication never grants identity, delegation, authorization, signing, payment, or provider authority.
