handler_contracts

Typed input/output contracts per handler type. When set, subscription staleness is driven by changes to these schemas rather than the handlers field. Contract fields are JSON Schema Draft 2020-12 documents.

training
object
input_schema

JSON Schema Draft 2020-12 document for the payload accepted by this handler. When set on inference, direct inference requests validate input against this schema before dispatch. Stored event-subscription payloads are validated against the target’s schema for the action (warnings-only on mismatch).

object
output_schema

JSON Schema Draft 2020-12 document for the handler’s successful output on job completion. Mismatches are logged as warnings but do not fail completion (external handlers may diverge).
