Rev. Lett. 134, 133603 (2025)] which attributes interference phenomena to detector-coupled (bright) and detector-uncoupled (dark) states of light, we develop a continuous-mode extension of the bright- and dark-state framework. This extension addresses a conceptual distinction between interference and diffraction, that is, the transition from a finite set of discrete paths to a continuum of modes. Through the construction of a complete detector-oriented basis for single-slit diffraction, we demons"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"the observed diffraction pattern arises from projection of the photon state onto a single bright mode by identifying the detectable and undetectable modes, with photons detected at intensity minima having zero probability, as they reside in modes spanning an infinite-dimensional dark subspace.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"That the bright/dark distinction introduced for a finite number of discrete paths in the cited PRL paper extends without additional postulates to a complete, orthonormal, detector-oriented basis for the continuous-mode single-slit case (abstract and §2–3).","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Diffraction arises when photons project onto one bright mode in an infinite-dimensional detector basis while all intensity minima lie in an undetectable dark subspace.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"Diffraction patterns arise because photons project onto one bright mode while occupying an infinite dark subspace at minima.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"6c31f38961fc2fa3e39f09d0fb19dfabd1212315d8c93466e0654ddf1e98835e"},"source":{"id":"2510.16329","kind":"arxiv","version":4},"verdict":{"id":"52e2b5f9-feb7-41b5-96f6-fc7729834b38","model_set":{"reader":"grok-4.3"},"created_at":"2026-05-18T06:50:58.135194Z","strongest_claim":"the observed diffraction pattern arises from projection of the photon state onto a single bright mode by identifying the detectable and undetectable modes, with photons detected at intensity minima having zero probability, as they reside in modes spanning an infinite-dimensional dark subspace.","one_line_summary":"Diffraction arises when photons project onto one bright mode in an infinite-dimensional detector basis while all intensity minima lie in an undetectable dark subspace.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"That the bright/dark distinction introduced for a finite number of discrete paths in the cited PRL paper extends without additional postulates to a complete, orthonormal, detector-oriented basis for the continuous-mode single-slit case (abstract and §2–3).","pith_extraction_headline":"Diffraction patterns arise because photons project onto one bright mode while occupying an infinite dark subspace at minima."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/2510.16329/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":2,"snapshot_sha256":"1f8ba4e4cd1ec8f467975c68753c0289c0175539399d1de1e260b9c26f23dd39"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
