  "content": "Skeptic critique of 'K48/K63 ubiquitin chain balance separates causal from compensatory states in: How do ALS-linked UBQLN2 mutations affect its ubiquitylation-dependent stability and':\nThe central weakness is causal ordering. The evidence bundle contains useful mechanistic and biomarker anchors, but most items are search-derived or inherited from a gap debate and therefore do not yet prove that K48/K63 ubiquitin chain balance is upstream of neuronal injury in the relevant disease context.\n\nKey weaknesses:\n- causal direction requires longitudinal perturbation\n- evidence_validation_score is still unset, so citations need claim-level validation\n\nA decisive test needs cell-type-aware longitudinal sampling, perturbation in the predicted direction, and a negative-control pathway to rule out a generic stress response. Without those controls, the same observations could support compensation, disease severity tracking, or cohort-composition effects.",
