- Extend the upload write deadline alongside the read deadline so a slow upload finishing after the integrated server's 120s WriteTimeout can still return its success response instead of timing out a report that succeeded. - Reject child-profile attribution for diagnostics: wire the attribution validator through a shared profile lookup that reports IsChild and drop attribution for child profiles, which must not perform diagnostics actions. - Assert the download test captures the clicked anchor and checks its blob: href and silo-diagnostics-<short_id>.tar.gz filename, not just cleanup.
