Error responses from the websocket multiplexer were missing the
request ID and using a bare string format instead of the structured
error protocol. This caused clients to hang when a request failed
(e.g. unsupported service for a flow) because the error could not
be routed to the waiting caller.
Include request ID in all error paths, use structured error format
({message, type}) with complete flag, and extract the ID early in
receive() so even malformed requests get a routable error when
possible.
Updated tests - tests were coded against invalid protocol messages
The metadata field (list of triples) in the pipeline Metadata class
was redundant. Document metadata triples already flow directly from
librarian to triple-store via emit_document_provenance() - they don't
need to pass through the extraction pipeline.
Additionally, chunker and PDF decoder were overwriting metadata to []
anyway, so any metadata passed through the pipeline was being
discarded.
Changes:
- Remove metadata field from Metadata dataclass
(schema/core/metadata.py)
- Update all Metadata instantiations to remove metadata=[]
parameter
- Remove metadata handling from translators (document_loading,
knowledge)
- Remove metadata consumption from extractors (ontology, agent)
- Update gateway serializers and import handlers
- Update all unit, integration, and contract tests
