Overview

Package observation defines host-facing runtime observation DTOs.

Runtime events are presentation-neutral facts, and those facts may still be too low-level for a host UI or API response. Package observation projects selected events and narrow observation DTOs into stable, UI-neutral status records that a host can render without parsing assistant text, exposing prompt-cache storage records, or depending on internal inspection types.

Observation values are not raw debug records. They intentionally omit provider payloads, model deltas, reasoning, tool arguments, tool results, and local paths. Hosts that need raw local inspection should build that capability as an explicit privileged surface behind its own product boundary.
