**Architecture:** Local data pipeline turns SuttaCentral (Bilara) CC0 translations into (a) a LanceDB citation index and (b) synthetic instruction pairs generated with Claude Sonnet 5 (Batches API). `mlx_lm.lora` trains a QLoRA adapter on the M5. An eval harness collects responses from 4 systems and judges them with Claude Opus 5.
