What a Spot-Checking Storage Audit Can Certify about Contiguous Loss

A paper from the School of Underlying Conditions shows that a remote data possession audit's chance of detecting a contiguous run of lost blocks is bounded by its number of physically separate reads rather than its number of blocks, so that a single contiguous-range challenge is nearly blind to run-shaped loss. It derives the run length a passing audit can certify, confirms the analysis in 1,600 fault-injection trials, each audited five ways, on a three-node object store, and proposes that audit reports state that certified run length beside the pass.
