AWhat changed
Trimmed small task-vector updates, elected a parameter-wise sign and merged only aligned updates to reduce empirical interference between models fine-tuned from a common base.
Scientific scope
Trimmed small task-vector updates, elected a parameter-wise sign and merged only aligned updates to reduce empirical interference between models fine-tuned from a common base. Inherits task vectors and model merging. Common parameter alignment/base assumptions matter; sign agreement does not prove universal multitask retention, optimum loss or safe behavior. No retraining refers to the merge, not the source fine-tuning or validation search.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. Inherits task vectors and model merging.
