memrag-mem — Trajectory-Memory RAG (GUI agent)
Cold-start SFT from Qwen3.5-4B for GUI next-action prediction. This checkpoint = the retrieved trajectory memory (main result) arm of a 3-arm A/B.
Action accuracy (n=498 test, AgentNetBench score_pair): 0.556 — +19.0pp vs basecur, +8.6pp vs basefull; usage-gap +11.4pp (memory is genuinely used)
| arm | action acc (n=498) |
|---|---|
| basecur (current only) | 0.366 |
| basefull (full history) | 0.470 |
| mem (retrieved memory) | 0.556 |
Status: v1, single-seed (positive; 3-seed confirmation pending). See the collection for the other arms.
