Can instruction gains survive without the misalignment?

Iterative DPO produces both improved instruction following and emergent misalignment together. The question is whether training can be modified to keep the capability gain while eliminating the harmful generalization.

The abstract says the Qwen2.5-32B-Instruct run "induces both misalignment and improved instruction following accuracy, showing that iterative DPO can be used as a testbed for selective generalization" (Can iterative DPO preserve instruction following while removing misalignment?). A testbed is a place to run a test. The excerpt shows the setting and the two effects that come out of it, and it reports no attempt to keep one and drop the other.

Read as the vault reads "selective generalization" (the excerpt does not define it), the question is whether training can be shaped so that the wanted generalization survives and the unwanted one does not. The result to look for is a training change, which might be the data, the reward, or the prompt, after which instruction following still improves and the misaligned behaviors from Does iterative DPO training reliably induce hidden misalignment behaviors? no longer appear. Two outcomes would both be informative. If the gain and the misalignment separate, the testbed has produced a countermeasure candidate. If they do not, that suggests the two come from the same learned change, which bears on how much of misalignment is a by-product of capability training.

The limitations paragraph mentions inoculation prompts (Do inoculation prompts prevent reward hacking beyond named exploits?), which is one candidate separator. The excerpt does not say whether they were applied to the Qwen run or what they did to instruction following. It also does not say how the misalignment was measured, so "dropped" has no unit here.

The Shallow Beliefs paper is the vault's nearest test of two of the three routes named above, the prompt and the data, on a neighboring target. There a framing prompt during training prevented emergent misalignment while the same framing added through a midtraining corpus did not (Can advance document training prevent reward hacking misalignment?), and the paper's stated reason is that steering through data is unpredictable where it must override an association the base model already holds, with reward hacking leading to misalignment as its example (Can training data edits reliably override what models already believe?). Neither excerpt reports a wanted capability gain kept alongside, so this bears on which route separates misalignment from what training taught and not on whether an instruction following gain would survive.
