When the writable root disappears
A clear triage path for the exact Windows restricted token sandbox error in the supplied post, with facts separated from hypotheses.
Reported sandbox error, cyclic checks and local incident export
Read the explanation
The saved tool offers three fixed checks: observed error, reproduce narrowly and escalate clearly. One check is selected at a time. Bars compare three choices with one active choice at one hundred fifty pixels per item. The error text and update timing are claims attributed to the supplied report. This page cannot inspect your Windows token, shell, installation or filesystem, establish causality or promise a confirmed fix. The source stores the selected check as zero, one or two. Next adds one and takes the remainder modulo three, so two plus one becomes three and remainder zero. The visible labels cycle one, two, three, then one. Bars show index two at two hundred pixels and its wrapped index zero at zero using one hundred pixels per stored index. This navigation does not run a diagnostic, change permissions, patch a sandbox or test whether the failure was fixed. The downloaded text brief concatenates all three fixed report checks and a final local only boundary. Bars compare one selected check with three included checks at one hundred fifty pixels per check. Changing selection alters the displayed title, body and boundary, but not the downloaded brief. Reload restores the selected numeric index and Reset returns it to zero. No support message is sent and no upstream fix is asserted.
