2026-10-03FR-QE-0008Normal Record Review of RR-2026-10-03-01 admitted Burt et al., arXiv:2610.01923v1, as distinct protocol-design evidence for loss-tolerant distributed lattice surgery. The 50% interface-erasure result assumes absent local noise; local errors mask the interface-distance advantage at 10^-3 circuit/resource error and gains strengthen at lower noise. This is not an experimental system-scale suppression result. AS-003 remains current; FR-QE-0008 stays RESOLVING / VS-04. No open question or claim change.Resolving
2026-09-26FR-QE-0008Normal Record Review of RR-2026-09-05-01 admitted Berthusen et al., arXiv:2609.03194v1, as distinct trapped-ion architecture evidence. The reported logical QEC cycle, Clifford benchmark and surface-code interface do not establish increasing-distance suppression, independent replication or useful fault-tolerant economics. AS-003 remains derived current assessment at RESOLVING / VS-04. The retrospectively incomplete Scout stated 4 September as first public date; arXiv v1 was submitted 2 September 2026, inside its review window.Resolving
2026-09-18FR-QE-0008Normal Record Review admitted Sivak et al., Nature 655 (2026), reinforcement-learning control of QEC. Experimental Willow results show continuous syndrome-driven control improves logical stability against injected drift and supports uninterrupted calibration; distance-15 evidence is simulation only. AS-003 appended; RESOLVING / VS-04 retained. RM-001 and AT-001 consistency wording completed from the authorised LPR-001-D20 correction and updated to reflect that drift mitigation does not remove correlated-error floors or satisfy the outcome-based attractor.Resolving
