Manifest format

For a TS realm, generated by embabel-build-manifest (provided by @embabel/runtime-types) — never hand-authored. A wasm realm with no TS build hand-authors the same format (see Execution hosts). The host reads it at install time.

Field	Source	Purpose
namespace	src/api/<filename>.ts (kebab-case → snake)	Gateway namespace; LLM sees this camelCased (docs_editor → docsEditor).
name	exported function name	Method name on the namespace.
description	first JSDoc paragraph	LLM-visible documentation.
inputSchema	TS type of args parameter	JSON Schema; drives the typed surface on the LLM side.
outputSchema	TS type of the unwrapped Promise<T>	Same.
schedule	manifest author	Optional cron expression (Spring 6-field); the host also runs the Realm Function on this cadence. See Execution hosts.
onType	export class X extends Entity methods (or manifest author)	The entry is a method on a declared type, surfaced as <obj>.<name>(args) rather than a bare gateway function.
className	exported class name	Set for class-based type methods; the class to instantiate before invoking name. Absent for the function form.
