CapabilityCall

One capability invocation, addressed to a provider node.

Attributes: call_id: Caller-minted correlation id (opaque string, unique per call). capability_id: The capability's id from its descriptor. version: The exact negotiated semantic version. descriptor_revision: The revision digest the caller discovered, so the provider can reject a drifted contract (revision_mismatch). caller_node: Node id of the caller (identity, not authorization; the fabric is trusted). target_node: Node id of the provider being called. timeout_seconds: Deadline the provider must honor for this call. payload: The opaque call payload; validated against the descriptor's input_schema on the provider before the handler runs.
