 * - Entries are split on commas and trimmed. An empty entry (e.g. a trailing
 *   comma or `a,,b`) is a malformed `EMPTY_ENTRY`; a non-UUID entry is
 *   `INVALID_UUID`.
 * - Valid ids are lower-cased and de-duplicated, preserving first-seen order.
 *
 * Pure utility — does not consult auth state and is not wired into auth
 * decisions here.
