delegate_task gains caller-declared output contracts.
An optional output_schema (JSON Schema) per task item and on the single-goal form. The child receives it as an explicit OUTPUT CONTRACT block; the parent validates the final answer with jsonschema and, on failure, sends exactly one bounded retry turn carrying the validation errors verbatim. Result entries gain schema_valid, plus schema_errors and schema_retries when relevant -- only when a schema was requested, so schema-less delegations keep a byte-identical result shape. Malformed schemas fail loudly at dispatch before any child spawns.
Channel: tagged-release. Ancestry: merge_commit_sha 0ebaa490b515cc0a1cdaa6f8df7b20d94cf990b9; compare/0ebaa490...v2026.8.13 -> status=ahead, ahead_by=1154, behind_by=0 (ancestor of stable tag v2026.8.13).
Operator consequence: Try it wherever you currently parse subagent prose with regex. It converts 'the child returned something' into a checkable assertion with a bounded repair loop, and the wire shape for existing callers is unchanged, so adoption is per-call rather than a migration.
