Focus: the original gamma-ray microscope setup and assumptions; Heisenberg’s heuristic estimate versus Kennard’s formal state-preparation inequality; measurement disturbance versus state-preparation uncertainty; Heisenberg’s report of Bohr’s critique; and later measurement-disturbance work and experiment. Article prose revised only where necessary for source accuracy. This status records source traceability, not truth of disputed interpretations, consensus, exhaustive literature coverage, or expert approval.",
  "summary": "Heisenberg’s relevant 1927 passages, the SEP treatment, and the cited experiment support the revised distinctions between the microscope’s approximate δqδp ∼ h estimate, the Kennard state-preparation inequality, and error–disturbance relations. The article qualifies aperture, recoil direction, Bohr’s reported objection, and the experiment’s scope. Independent review found no material issue.",
