2026-08-28FR-QE-0007IN-006 appended — Google Quantum Echoes and the connected molecular-geometry OTOC programme. Classified as partial evidence: reproducible beyond-classical performance and practical application relevance are both present within the programme but not at the same demonstrated scale. Instance logged before AS-002; no state or verification-stage change at this step.Fragmenting
2026-08-08FR-QE-0004IN-009 appended following operator approval of Post-Scout Human Record Review flag 2026-08-08-01. The D-Wave dual-rail entangling-gate result (Nature, DOI 10.1038/s41586-026-10822-y) is logged as bounded SUPPORTIVE component-level evidence for the scalable-architecture element of the claim. It preserves a favourable erasure-biased error hierarchy during an essential two-qubit operation, but does not demonstrate a logical qubit, integrated below-threshold error correction, measured logical suppression with increasing code distance, d=11-and-above scaling, or realistic full-system operation; favourable code-distance behaviour remains simulation-derived. Instance-level append only; no assessment issued; pressureState RESOLVING, verificationStage VS-04, mechanisms, openQuestions, and new-record disposition unchanged.Resolving
2026-07-22FR-QE-0001Append-only canonical reassessment issued after completion of the governed FR-QE-0001 inquiry. Institutional verdict: UNRESOLVED AT THE ORIGINAL COMPARISON POINT; LATER SUPERSEDED. Pressure State changed from FRAGMENTING to STABILISING because successor claims, including Willow, are outside the admitted claim's material commitments and the remaining uncertainty is bounded. Verification Stage changed from VS-03 to VS-04 under the canonical evidence-depth semantics because independent classical work directly reproduced and ultimately counter-performed the constitutive benchmark comparator. VS-04 is claim-level adversarial replication, not independent reproduction of Sycamore hardware. AS-001 and all earlier history remain preserved.Stabilising
