## Identitäts-Vertrag, KOLLISION ALLER OBJEKTE (Military-Pack-Umstellung,
## 25.10.2026): JEDES Registry-Objekt läuft durch die Kollider-Bauer aller drei
## Projekte —
##   A) Editor  (KolliderBau.kollider)
##   B) Client  (SvmapWorld._collider)
##   C) Server  (SvmapLoader._object_body)
## und druckt je Objekt `IDENT k_<oid>=<Formen>|<Typ-Zähler>|<Gesamt-AABB>`
## (Maßstab 1.7, damit scale-Fehler auffallen). Der Runner
## (run_kollision_alle_identitaet.sh) verlangt IDENTISCHE Zeilen in allen drei
## Projekten — Editor-Playtest, Quest-Client und Server kollidieren dann überall
## gleich (Trimesh, Verbund, Stamm, none).
## Das Skript liegt im EDITOR-Repo und wird je Projekt gefahren:
##   godot4 --headless --path <projekt> -s <abs>/tests/probe_kollision_alle_ident.gd
## Bewusst load() statt class_name (läuft in DREI Projekten).
