+
+Training prompts for score-conditioned SFT / RL and separate reward-model pair sets; nothing here is scored.
+`sft-prompts/train` and `rl-prompts/train`: the same prompt pool, deduplicated across sources with responses
+merged and HH/PKU test prompts removed. `rl-prompts` additionally marks `selection=pku_label_conflict` where PKU's
+better and safer labels disagree with opposite safety flags; `preference_pairs` indexes those responses.
+This is an annotation, not a filter or a sampling weight. Both configs are train-only; evaluation prompts are
+prepared by the evaluation processor. Strata are source proxies, not content labels: `benign` (HH helpful-*),
+`harmful` (HH harmless-base, PKU with an unsafe response), `unlabeled` (PKU with two safe responses).
+
+`helpful-rm` train: HH helpful pairs; PKU pairs whose two replies are both safe (better label, safety held
+constant); a small answer > refusal augmentation on Guard-Safe HH helpful-base prompts, negatives alternating
+fixed templates and transplanted HH harmless-base refusals. Test keeps every PKU pair. `harmless-rm`: HH
+harmless-base pairs and PKU pairs with one safe and one unsafe reply (safe > unsafe). Both heads receive
+the same benign answer > refusal pairs, at most 15% of the smaller final training split.
+Standard chosen/rejected pairs only: no judge labels, no ties, no label flips, no manufactured conflict.
+Harmless therefore includes appropriate responses to benign requests, rather than pure content safety.
+Guard screens requests only; it does not certify answer correctness. Native pairs are length-balanced
+(chosen longer by >20 words subsampled to match rejected longer), then shared augmentation is added.
+Augmentation can retain length bias; its length counts and realized shares are reported. Sources: Anthropic/hh-rlhf,
+PKU-Alignment/PKU-SafeRLHF.
