# decay demo 1. A few exchanges set goals, make decisions, and leave one task half done. 2. `/compact`: Decay replaces Pi's summary with structured memory, classifying what happened into atoms: goal, decision, constraint, state, blocker. 3. The compaction summary that lands in context is terse, structured, and recency-weighted: the latest decision wins, superseded ones are marked. 4. The context meter drops; the next prompt still knows the open task and the decisions. Protagonist: decay. Supporting: context-size for the meter, continuity picks up the unfinished task. Point: compaction that keeps decisions and state, not prose.
