Spec 2026-07-28 readiness
No runtime readiness verdict: this server has no keylessly reachable conformant MCP endpoint (package-only, auth-gated, or down at census time), so its behavior against the 2026-07-28 revision cannot be measured without credentials. Absence of evidence is recorded as absence, never guessed. Ecosystem numbers: the readiness report.
