/**
|
|
* Every user belongs to exactly one group at all times — a real group, or the
|
|
* NOGRP placeholder if they haven't been assigned one yet. NOGRP is a normal
|
|
* row-backed group (not a computed "users with no group" view), so every
|
|
* writer that moves a user in or out of a real group must also keep their
|
|
* NOGRP row in sync. This util is the single place that invariant is
|
|
* enforced — see project memory "NOGRP dual-membership fix" (2026-07-15) for
|
|
* the bug this replaced (users silently stuck in both NOGRP and a real group).
