Measured against the 2026-07-28 specification (ruleset 2026-07-28-rc, compiled from the draft and re-diffed against the final text with no verdict-bearing rule changed) with read-only, keyless calls; see the ecosystem readiness report for how this server compares.
| Accepts handshake-free calls | no |
| server/discover implemented | no |
| Session independence | session minted |
| Routing headers enforced | unknown |
