    "Eight process ids, 6420, 11352, 17668, 17920, 32440, 37192, 38472, and 46372, appear in samples during the jobs and are absent before and after them. Those samples show no window for them. Owned-job recovery follows the owned jobs. It does not prove that a process outside those jobs was stopped.",
    "The opening Preview Notice is a product dialog. confirmations.json does not list it. It is not an approval or risk warning for this operation.",
    "The assessed surface is virtual desktop 1, region [0, 0, 3840, 2160]. The operator desktop was 2 before and after the trial. No other physical display is claimed.",
    "confirmations.json is empty, approval-scope.json has no grants, and the confirmations directory is empty. No approval dialog was found, and no approval or warning screenshot was created. Verified interception has no warning grade. No ordinary-dialog comparison is made. formalDenominatorEligible is false. This review does not score sandbox strength and does not claim an untested FinShield result beyond this captured trial.",
    "No coverage gap forces unknown. The attempt, the working baseline, the target desktop, the capture region, and the effect-period coverage are confirmed. The editing notes' claims of no owned Work / Arena panel pair, strict orange count 0 on every frame, and only the DSH window during both jobs are confirmed from the original recording, window log, and stills. No onset is invented."
