"""IMA — Intelligent Memory Arbitration Engine.

5-stage pipeline that decides what to remember, how deeply, and at what cost:
  1. Classification (local heuristic) — filter trivial content (~70% eliminated)
  2. Duplicate Check (local embedding) — merge near-duplicates
  3. AI-Powered Depth Decision — ask user's chosen AI for importance/detail
  4. Smart Compression — store as full/summary/key_only
  5. Store + Link — persist and link related memories
