Compression Remembers the Detour: How Context Compression Amplifies Off-Task Content and Derails LLM Agents
This work formalizes CIGD via the drift amplification ratio (DAR), evaluates six compression strategies on a controlled injection benchmark ( per cell), and proposes Goal-Anchored Compression (GAC): a pinned goal anchor, a negation ledger, status-aware retention scoring, and drift re-anchoring.
