So the fix is invariance, not a lower harm threshold --\n# and that distinction is the whole ballgame, because every OR-Bench over-refusal\n# probe is a RAW prompt that is benign but *reads* harmful (\"...ensuring all laws\n# are followed\", \"...for a movie stunt\"). Lowering the harm threshold moves ASR a\n# little and over-refusal a lot; under a harmonic mean that is a net loss.\n# Ablations proving this (multi-pass means) are in /workspace/ABLATIONS.md.\n#\n#   A) REFUSE side. Take only the harmful prompts the base ALREADY refuses cleanly\n#      when unwrapped, and train its OWN refusal text as the target under the three\n#      wrapped views (refusal_suppression / prefix_injection / base64). No raw view.\n#      Nothing new is being installed: the target is behaviour the model already\n#      produces for that exact request, so the raw decision boundary cannot move by\n#      construction -- only \"the wrapper does not change my answer\" is learned.\n#\n#   B) COMPLY side, same wrappers. Benign prompts wrapped in refusal_suppression and\n#      prefix_injection, targeting the base's own compliant answer. This is what\n#      protects helpfulness: without it the model learns \"odd wrapper => refuse\".\n#      It matters most for refusal_suppression, which is structurally a rule-list\n#      prompt -- exactly like an IFEval constraint prompt -- so this is what keeps\n#      \"rule list => refuse\" out of IFEval. (base64 is not used on the benign side:\n#      the base hallucinates the decoding, so self-distilling it would teach\n#      confabulation, and the eval never wraps a benign prompt in base64.)\n#\n#   C) RETAIN anchors. The base's own answers to ordinary benign prompts, plus\n#      gray-zone (professional-advice / politics) prompts kept ONLY where the base\n#      already answered. Gray-zone rows are also EXCLUDED from (A): they are not\n#      StrongREJECT harm categories but they are precisely the shape of OR-Bench\n#      hard probes, so refusing them buys no safety and costs over-refusal.\n#      Retain is deliberately the dominant term (~72% of the gradient): over-refusal\n#      is monotone in the refusal share, and -- the surprising part -- so is ASR.\n#      Sweeping the share at fixed data moved both the same way:\n#          41.3% -> ASR 5.33 / OR 20.83      35.3% -> ASR 5.18 / OR 14.29\n#          28.1% -> ASR 4.52 / OR 14.12      21.5% -> ASR 7.09 / OR 16.67  (turns)\n#      i.e. leaning HARDER on the retain anchor made the model both safer and less\n#      trigger-happy, up to a floor. Down-weighting safety is not a concession here;\n#      it is the win. (The direction is solid; 28.1% as the exact optimum is not --\n#      the gap to 35.3% is within the draw-to-draw spread of finding 5.)\n#\n# Every retain/comply target is SELF-DISTILLED from the frozen base under the exact\n# frozen eval decoding (greedy, seed 20260616, thinking off, base chat template), so\n# the retain term anchors behaviour at ~zero KL (observed retain CE 0.11-0.15 at\n# step 0) instead of dragging style and length around. The provided Alpaca `output`\n# fields are short, stylistically alien to Qwen3 and ~12% truncated mid-word;\n# training on those would cost IFEval.\n#\n# Loss is completion-only (prompt tokens masked to -100) and normalised PER EXAMPLE\n# before averaging, so the mixture fractions mean what they say -- a ~50-token\n# refusal and a ~300-token retain answer get equal weight per example instead of\n# retain silently getting 6x the gradient.\n#\n# Data: only /workspace/data/*.jsonl + the eval's own frozen transform definitions\n# (/workspace/eval/strongreject_transforms.py).

It stops refusing once the\n# same request is wrapped. So the fix is invariance, not a lower harm threshold --\n# and that distinction is the whole ballgame, because every OR-Bench over-refusal\n# probe is a RAW prompt that is benign but *reads* harmful (\"...ensuring all laws\n# are followed\", \"...for a movie stunt\"). Lowering the harm threshold moves ASR a\n# little and over-refusal a lot; under a harmonic mean that is a net loss.\n# Ablations proving this (multi-pass means) are in /workspace/ABLATIONS.md.\n#\n#   A) REFUSE side. Take only the harmful prompts the base ALREADY refuses cleanly\n#      when unwrapped, and train its OWN refusal text as the target under the three\n#      wrapped views (refusal_suppression / prefix_injection / base64). No raw view.\n#      Nothing new is being installed: the target is behaviour the model already\n#      produces for that exact request, so the raw decision boundary cannot move by\n#      construction -- only \"the wrapper does not change my answer\" is learned.\n#\n#   B) COMPLY side, same wrappers. Benign prompts wrapped in refusal_suppression and\n#      prefix_injection, targeting the base's own compliant answer. This is what\n#      protects helpfulness: without it the model learns \"odd wrapper => refuse\".\n#      It matters most for refusal_suppression, which is structurally a rule-list\n#      prompt -- exactly like an IFEval constraint prompt -- so this is what keeps\n#      \"rule list => refuse\" out of IFEval. (base64 is not used on the benign side:\n#      the base hallucinates the decoding, so self-distilling it would teach\n#      confabulation, and the eval never wraps a benign prompt in base64.)\n#\n#   C) RETAIN anchors. The base's own answers to ordinary benign prompts, plus\n#      gray-zone (professional-advice / politics) prompts kept ONLY where the base\n#      already answered. Gray-zone rows are also EXCLUDED from (A): they are not\n#      StrongREJECT harm categories but they are precisely the shape of OR-Bench\n#      hard probes, so refusing them buys no safety and costs over-refusal.\n#      Retain is deliberately the dominant term (~72% of the gradient): over-refusal\n#      is monotone in the refusal share, and -- the surprising part -- so is ASR.\n#      Sweeping the share at fixed data moved both the same way:\n#          41.3% -> ASR 5.33 / OR 20.83      35.3% -> ASR 5.18 / OR 14.29\n#          28.1% -> ASR 4.52 / OR 14.12      21.5% -> ASR 7.09 / OR 16.67  (turns)\n#      i.e. leaning HARDER on the retain anchor made the model both safer and less\n#      trigger-happy, up to a floor. Down-weighting safety is not a concession here;\n#      it is the win. (The direction is solid; 28.1% as the exact optimum is not --\n#      the gap to 35.3% is within the draw-to-draw spread of finding 5.)\n#\n# Every retain/comply target is SELF-DISTILLED from the frozen base under the exact\n# frozen eval decoding (greedy, seed 20260616, thinking off, base chat template), so\n# the retain term anchors behaviour at ~zero KL (observed retain CE 0.11-0.15 at\n# step 0) instead of dragging style and length around. The provided Alpaca `output`\n# fields are short, stylistically alien to Qwen3 and ~12% truncated mid-word;\n# training on those would cost IFEval.\n#\n# Loss is completion-only (prompt tokens masked to -100) and normalised PER EXAMPLE\n# before averaging, so the mixture fractions mean what they say -- a ~50-token\n# refusal and a ~300-token retain answer get equal weight per example instead of\n# retain silently getting 6x the gradient.\n#\n# Data: only /workspace/data/*.jsonl + the eval's own frozen transform definitions\n# (/workspace/eval/strongreject_transforms.py).
