Minor correction in session_memory.ipynb #2187
Description
Love these kinds of explainers - they make the implementation details much easier to reason about.
Small issue:
In the example with keep_last_n_turns=2 and context_limit=4, the text says:
“everything before the earliest of the last 4 turns is summarized into a synthetic pair, and the last 2 turns remain verbatim.”
This wording is a bit misleading - it suggests that turns 3 and 4 are neither summarized nor kept verbatim.
Based on the code (user_starts[-keep_last_n_turns]), it seems the correct description is “earliest of the last 2 turns.”
Adjusting that line would make it clearer that no messages are dropped from both the summary and the preserved context.
