validate_extract_schema

Validate an extraction schema without creating a job or consuming credits.

Cost class: fast (pure validation, no I/O, no model inference).

Use this before submitting an extract job to catch schema errors up front. On success valid=True and normalized_schema carries the compiled form the extraction pipeline will use. On failure valid=False and errors lists every violation — the whole list, not just the first.

Args: body: Exactly one of schema_id or schema. Optional schema_version pins a registry version when schema_id is set. caller: Authenticated tenant used to resolve tenant/platform schemas. session: Database session.

Returns: An :class:ExtractSchemaValidationResponse.

Raises: PlatformError: schema_not_found when schema_id is unknown.
