Give long-horizon agents unbounded working memory with typed, dependency-linked context eviction (CWL)

arXiv:2606.11213·medium signal

'Beyond Compaction' (arXiv:2606.11213) proposes Context Window Lifecycle, where the agent annotates its trajectory as typed, dependency-linked episodes and a deterministic, LLM-free policy evicts content in priority order whenever the token budget is exceeded. Unlike summarization-based compaction, eviction is cheap (no extra model call) and dependency-aware (it won't drop context a later step still needs). For builders running multi-hour agents, this is a concrete recipe for staying in-budget without paying a summarizer tax every turn.
