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 Institutional verdict: UNRESOLVED AT THE ORIGINAL COMPARISON POINT; LATER SUPERSEDED.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
2026-07-14FR-QE-0006IN-006 appended — composed logical Clifford operations via lattice surgery (arXiv:2607.01473), surfaced from Frontline Scout report 2026-07-03 during evidence-gap review as non-duplicate evidence stranded in the Scout archive. Instance-level append only, classified NEUTRAL: an active-computation building block advancing the fault-tolerant substrate beyond IN-003's application-ready-in-principle status, which does not demonstrate a practically useful algorithm beyond classical simulation (Clifford-only, distance-three, no target problem — BN-001 untouched). No assessment issued; pressureState ESCALATING, verificationStage VS-02, mechanisms, and openQuestions unchanged. The source retains its separate Scout FCIF-candidate status; this instance does not pre-decide that.Escalating
2026-07-03FR-QE-0004IN-006 added — Legg et al. Nature critique and Microsoft response, bearing on IN-005's pending-verification status. Initiation: Evidence Gap Scan Pilot 001 (Candidate 1). Scope: instance-level only; no Assessment issued; pressureState, verificationStage, and openQuestions unchanged.Resolving
