Source text was not altered except for truncation to a realistic tool-result length, and surface augmentation (casing, punctuation, filler) applied to user turns in training copies only. ## Search queries — derived, not generated Every `` query in the training data is the subject of the question, derived mechanically from the human-written sources above. No language model wrote any training query or any training reply. No real user data was used. Model weights: MIT.
