# `[2026-09-11]` BabyYarros COMPLETE — both arms trained AND evaluated; the voice moved toward Yarros above the measured noise

⭐⭐ **BabyYarros COMPLETE — both arms trained AND evaluated; the voice moved toward Yarros above the measured noise floor, and the instruct arm renders beats 9/10.** Training: **Base best held-out 2.5263 @ ckpt-125** (overfits within the epoch — best is the checkpoint, not the shipped step-178 adapter), **Instruct 2.6114 @ 178** (still descending, undertrained if anything). Base-wins-held-out / Instruct-holds-instruction replicates Brontë at a near-identical **0.085-nat** gap. **Eval (gx10, seat-free, done during the Anaheim outage):** three voice arms + instruct beat→paragraph. `delta_cb` (Burrows over char-bigrams vs held-out Yarros) ordering **base-125 0.549 < instruct 0.631 < base-unadapted 0.706**, same-author target 0.463; both adapters clear the **0.046 measured noise floor** (within-arm seed spread, not the same-author distance — first cut mis-framed that) — base **+0.157**, instruct **+0.076** vs control. ⚠ One seed-pair per arm, so the ordering CORROBORATES the independent held-out-loss ordering rather than settling it. **Beats (instruct, chat template, Yarros SYS): on-beat 9/10** (it takes direction after raw-text training — the Skaldsong question, answered yes), in-band 5/10, ran-on 7/10 (length + clean-close discipline is the weak axis, same trade as Brontë). Booth: **http://10.100.10.50:8090/b/babyyarros-voice/**. Tooling `scripts/r49-corpus/{voice_prompts_yarros.json,gen_beats_chat_yarros.py,voice_distance.py,build_booth_yarros.py}`, commit `5558d9c`. ⛔ **DEFERRED to power-return** (needs the ana-ml2 gen seat): the frozen adjudication's romantasy control panel, a 2nd seed, and the beat-incumbent leg.
