Opaque provider continuation data preserved across AG-UI runs. Hashbrown does not inspect or display this value.

Provider metadata preserved across AG-UI runs.

Human-readable reasoning. When reasoningDetails is present, this value is derived from the ordered records' nonempty content.

Ordered AG-UI reasoning records, including opaque continuation data such as encrypted values, subagent run IDs, and metadata. When present, these records take precedence over reasoning.

Tool calls the agent server executed itself, in the order the model made them, as ServerToolCall records. Present only when the message carries at least one.
