    "summary": "Giustina and colleagues reported a violation of a Bell inequality using entangled photons, rapid setting choices and high-efficiency transition-edge detectors in a Vienna experiment. The analysis reported a local-realism p-value no greater than 3.74 × 10⁻³¹ under its stated statistical and predictability assumptions.",
    "boundary": "The source measures photons at stations about 58 m apart and uses locally defined trials and detection windows; its spacelike separation depends on calibrated timing and the assumption that the measurement outcome is fixed at photon absorption. Random-setting independence is an assumption, not an experimentally complete exclusion of every hidden-variable explanation. The small p-value concerns the specified local-realism hypothesis and does not eliminate systematic or human errors. Supplementary timing and statistical derivations and raw data have not been replayed.",
