1.21.0

MCP-Registry federation returns one record per server name (the registry's isLatest marker wins; deterministic greatest-version fallback). Readiness checks of nessgate.com's own endpoints run through the in-process router instead of misreporting the service unreachable. Deterministic offline gate (npm run gate) now backs CI and both package publish workflows. Dual-era MCP support (2026-07-28 server/discover alongside initialize-based revisions), A2A v1 interfaces, and oversized-read honesty shipped in 1.20.0; library registry federation and declared-pointer delegation in 1.19.0. Companion package @nessgate/inspect 0.1.x: inbound-request inspection with hardened fetching (per-hop redirect validation, DNS checks, size and key caps) and the current Signature-Agent dictionary form.
