# Architecture notes (high level) This repo compares a dense baseline vs a structured "dual-stream" model on synthetic compositional tasks. Key stabilized regime (what produced the replicated ood_long gains): - chiasm_mode = bias (no information starvation) - curriculum mixing that includes long+gap samples during training - Schedule-2 with ramp; braid rehearsal prevents late-phase regression See `docs/preliminary_results.md` for the replication panel and ablations.
