1//! What each iteration is allowed to remember.
2//!
3//! A loop that re-sends every prior episode grows its own prompt without bound
4//! and bills accordingly; a loop that sends nothing produces the byte-identical
5//! prompt it already failed with. Neither is acceptable for a run measured in
6//! weeks, so each iteration is compressed to a summary and only the last few
7//! summaries are carried forward.
