 * Permissions tab exposes the bindings as Agent access, while installs remain
 * a separate "always loaded" choice. If the profile has no bindings yet, the
 * install state remains the safest legacy fallback.
 *
 * That fallback is the important part. It used to return "all agents" for an
 * unbound profile, which turned any unrelated save into a silent company-wide
 * grant from a control the reader could not see. Installs authorize their
 * targets, so mirroring the install state is both the truthful reading and the
