Before each driver call, over compact_at (0.6) of the prompt budget, the same model is asked for notes over the very request it was about to get, plus one message, so the server's cache covers all but the notes. The notes, with code's list of the calls they replace, become a compaction event that renders in place of its range, keeping word for word what started the work and the last few turns. Rare, large steps keep the prompt's start unchanged between them. A later compaction folds in the earlier; one from an earlier run's view is hidden. Failed notes are logged and fitting takes over. Fitting now applies compactions before it measures, records what it cuts (Trim) and logs each cut as context.trimmed. Wired into both agents' drivers and the benchmark; nisse-dev's helper loop is a follow-up.
