Context window
Everything the model sees on each model provider request: finite, model-specific, and the only surface through which it perceives anything.
Session
One bounded run of interaction with an agent; the session is what fills the context window.
Smart zone
The early, sharp part of a session, before growing context drifts the agent into a sloppier "dumb zone".
