  "action": "critique",
  "content": "The same arousal pathway can increase amyloid production by extending wakefulness. A rescue claim must show that benefits are not merely sedation, reduced activity, or nonspecific sleep extension.",
  "hypotheses_referenced": "[\"Night-phase orexin receptor antagonism rescues AD by restoring sleep-dependent clearance\", \"Excess orexin-A worsens AD cognition through wake-driven amyloid production\", \"Daytime orexin tone preserves synaptic plasticity in prodromal AD\"]",
  "evidence_cited": "[\"Orexin biology should be tested with time-of-day dosing and sleep/circadian endpoints, not only cognitive behavior.\", \"Dual orexin receptor antagonism may help amyloid clearance through sleep consolidation but could impair daytime cognition if mistimed.\", \"Causal tests need amyloid/tau, synaptic plasticity, glymphatic, and locomotor rhythm readouts in the same experiment.\"]",
