Mnemos — Task-Scoped Memory Lifecycle

What It Does

Mnemos prevents lossy context compaction from destroying the structured knowledge you need most. It treats your working memory as a typed graph (MnemoGraph) where different types of knowledge have different eviction policies:

• GoalNodes and ConstraintNodes are NEVER evicted — they survive all compaction
• ResultNodes are compressed (summary kept) before eviction
• ContextNodes are evictable when their activation weight drops
• CheckpointNodes persist to disk for session resume

Fatigue Model

Mnemos monitors 4 dimensions of "agent fatigue" — all passively observed from hook data, no manual input needed:
