A chmod by bifrost, which is not in the Persona's group, clears the setgid bit, so files would take bifrost's group and the Persona's reader could not open them. Directories and files are now created with exact modes (fixed umask around mkdir and open), the room directory must have inherited setgid from the installer's Persona directory or the image is refused (store-failed), and the Persona directory is never chmodded. Adds behavioural redirect-refused and fetch-timeout tests. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
