Found while fixing alkhttp's HTTP-side instance
(review-001-publish-schema-validation-robust): the identical
warn-and-skip pattern exists at src/protocol/dispatch.rs:352-366 — a
compile failure of a Pub op's publish_schema proceeds with
validator: None, so arbitrary unvalidated JSON reaches the sink
handler over the wire. Suggested direction: fail-closed + per-
registration validator cache (worked shape in alkhttp 1572a9d,
src/gateway/schema_cache.rs) + registration-time schema compilation.
Single compile site verified (both pump arms consume the one
InFlightSink.publish_validator).
