r.streamHandler(...)
Overview
Section titled “Overview”r.streamHandler(...) — registers a streaming read handler: name, Zod
input schema, async-generator handler closure, plus optional access,
rateLimit, and escapeHatch rules (StreamHandlerDef carries all three
at runtime). Same header/body split and opaque single-reference case as
QueryHandlerPattern.
