    about the people or their things and claiming actions beyond writing in the chat.
++  `chat.member.turn` is the same member with tools: a Chat Completions request (Chat's system message, the transcript,

    `overview.source` says which (`local_model`, `paid`, `extractive`), and `gaps` lists what is missing (no local
    model, no speech-to-text, no budget). The output is not cached: callers keep it. Live's grant names
