 # Training
 
-LoRA fine-tuning pipeline for Timmy's sovereign model. No custom harness — just config files for existing tools.
+Transitional training recipes for Timmy's sovereign model. These files are
+useful as reference configs and export helpers, but they are not the canonical

-Replaces the `autolora` repo (1,500 lines of custom code → config + `make`).
+Canonical data should live in `timmy-home` under gameplay trajectories,
+research artifacts, and `training-data/` exports such as DPO pairs.

+## Status
+
+This directory exists to avoid re-growing a bespoke training harness while the
+system boundary is being cleaned up.
+
+- Keep thin recipes and export helpers here only when they directly support the
+  Hermes sidecar.
+- Keep generated data, DPO pairs, and other lived artifacts in `timmy-home`.
+- Prefer deleting stale pipeline code over expanding it.
