+/**
+ * Slice 2 van shaer-0j2 (FEP-7628, DRAFT): de UITGAANDE helft — deze Klonkt
+ * is het oude huis en kondigt het vertrek aan. Twee eisen voordat er iets
+ * de deur uit gaat:
+ *  1. Geen guardians: een warded account verhuizen zonder de guardianship
+ *     te hertargeten zou het vangnet van het kind stil breken; dat is
+ *     shaer-tge's gated beslissing, dus tot die er is weigert een bewaakt
+ *     account de verhuizing.
+ *  2. De NIEUWE actor claimt ons in alsoKnownAs — dezelfde back-reference
+ *     die elke ontvangende server (onze eigen slice 1 incluis) eist. Zonder
+ *     die claim is de Move overal dood bij aankomst.
+ * De Move gaat duurzaam naar elke volger-inbox; hun servers doen de
+ * re-follow. `moved_to` wordt hier vastgelegd; het SERVEREN ervan op de
+ * actor (en het beleid van de oude site) is slice 3.
+ * Deps injecteerbaar voor tests (geen netwerk in node:test).
