/**
 * Project ownership edge cases (GHSA-wrg5, codex round 2).
 *
 * The first predicate union'd "any linked event I can see" with the stored
 * owner, which opened two holes:
 *   - a project owned by B containing ONE legacy ownerless event became
 *     readable by everyone (and /overview aggregates B's other events,
 *     invoices and emails);
 *   - migration 167 deliberately leaves multi-owner projects NULL, and a NULL
 *     owner was treated as "everyone's".
 * The stored owner is now authoritative, and a NULL owner only derives access
 * when EVERY linked event is accessible.
