This paper defines always-on agents as persistent-state LLM systems, proposing a framework with a 10-stage lifecycle and five invariants for robust state governance. It introduces the Always-On Evaluation Protocol (AOEP-v0) which reveals that existing memory systems often fail critical governance obligations despite strong recall.

Key insights

  • Current research exhibits a significant imbalance, heavily emphasizing state accumulation and retrieval ("forward arc") while neglecting governance, recovery, and relinquishment ("return arc") operations.
  • Existing memory augmentation mechanisms primarily optimize for accumulating competence (plasticity) but often lack robust stability operators like validation, audit, forgetting, and rollback.
  • Dominant memory substrates (e.g., vector stores) are efficient for write/read but inherently lack native support for explicit governance features like authority, recoverability, and comprehensive deletion propagation.
