 On pushes, the `checks` matrix adds the push-only `compat-node22` lane. On pull requests, that lane is skipped and the matrix stays focused on the normal test/channel lanes.
 
-The slowest Node test families are split into include-file shards so each job stays small: channel contracts split registry and core coverage into eight weighted shards each, auto-reply reply command tests split into four include-pattern shards, and the other large auto-reply reply prefix groups split into two shards each. `check-additional` also separates package-boundary compile/canary work from runtime topology gateway/architecture work.
+The slowest Node test families are split or balanced so each job stays small: channel contracts split registry and core coverage into eight weighted shards each, auto-reply reply command tests split into four include-pattern shards, the other large auto-reply reply prefix groups split into two shards each, and agentic gateway configs are spread across the existing agentic Node jobs instead of running as one serial tail. `check-additional` also separates package-boundary compile/canary work from runtime topology gateway/architecture work.
 
 GitHub may mark superseded jobs as `cancelled` when a newer push lands on the same PR or `main` ref. Treat that as CI noise unless the newest run for the same ref is also failing. Aggregate shard checks use `!cancelled() && always()` so they still report normal shard failures but do not queue after the whole workflow has already been superseded.
 The CI concurrency key is versioned (`CI-v2-*`) so a GitHub-side zombie in an old queue group cannot indefinitely block newer main runs.
