Brain activity redirects where tau spreads in Alzheimer's

Epidemic model: firing neurons shift the threshold and course of pathology, and PET scans back the prediction.

Post-endpoint randomisation makes 'the past explains it' testable

A delay drawn after the endpoint is fixed becomes a probe; a surviving ordering rejects past-adapted sufficiency.
