classes.fresh chained WithContext onto a lazy NewDB session, which clones the
caller's statement with its conditions. A handle that carried a condition
made IsPrivilegedMember answer false for a member of a privileged group, so
the takeover guard would have let the request through. No caller passes such
a handle today: the admin hooks hand over the write's transaction handle.
- fresh builds the empty statement before anything is chained onto it
- IsPrivilegedMember and PrivilegedGroupIDs read through fresh
- permissions (the four Winter codes and manage_privileged_groups),
the user navigation item and the embedded admin YAML
- Users controller: list with deactivated users, row states, the
groups, created date and activated filters, and the form's name,
surname and email
- a member of a group in golem15.user.privileged_groups (default
admin) keeps their email, password and row unless the administrator
holds golem15.users.manage_privileged_groups; the refusal is a 403
that saves nothing
