Defined in:

Overview

One row per successful Llm::Client call: which provider/model actually served it, how many tokens it used, and what that cost at the time (using Llm::ProviderRegistry's pricing at the moment of the call, not whatever the registry says later — prices drift, history shouldn't).

Deliberately keyed by provider/model strings, not a credential_id — a credential can be reranked or removed, but its usage history shouldn't disappear with it.
