/// **Annex I note (c) of Commission Implementing Regulation (EU) 2026/2:** "In
/// the case of a consolidated disclosure, the subsidiaries discarding unsold
/// consumer products **shall be listed** in addition to the parent undertaking.
/// In the case of other groups consisting of independent undertakings and a
/// central organisation supporting the group … with a common brand name,
/// consolidated disclosure may take place on a shared website, provided that the
/// member undertakings are listed."

/// The list is not optional decoration on the consolidated arm — without it a
/// reader cannot tell which undertakings a figure covers, and the same tonnage
/// could be disclosed by a parent and omitted by every subsidiary with nothing
/// visible. So it is a field of the variant, and a standalone disclosure has no
/// place to put one.
///
/// Note also what note (a) does to the name: for a subsidiary in a consolidated
/// disclosure, the entity name is **the parent's**, not the subsidiary's.
