  "summary": "The record sealed on 31 July 2026 reports a replacement seven-hour laboratory soak with successful scheduled checkpoints and restoration of an older checkpoint. An earlier run exposed a defect that stopped repeated checkpointing; the record reports its correction and retest. It also discloses that cleanup destroyed the originally preserved checkpoint, so its restoration was not performed; the later restoration used a replacement artifact. One workload and one soak do not establish a general reliability rate. The separate 25-cycle sample supports only its stated confidence interval, not guaranteed success.",
