@ -360,6 +360,14 @@ Thermotoggle target temperature is also daemon-owned behavior state. Authored
data seeds it, adjustable commands mutate it, and its high/low-pass predicate
gates the same ordered chain.
Within one combat step, authoritative equipment, online state, durability, and
catalog payloads are read once into a tick-local operational behavior set.
Deployable, charged, constant, and instant weapon projections derive from that
same set. It is not persisted and cannot outlive the step; mutations still land
on the referenced authoritative item and behavior state. This prevents each
weapon family from independently rebuilding the same equipment graph without
introducing a cache owner beside the entity snapshot.
Migration target:
- blueprint/catalog rows define base stat ids and default values;
