WeaponItemData.AirburstRange (slot 29) becomes BlastRadius, same slot and
type so CultCache opens the catalog as compatible drift. A new nullable
slot 32 (30 and 31 belong to EquippableItemData) carries WeaponFuse?
Fuse. FireControl.Fire now decides "detonates" once, from BlastRadius
and Fuse directly, and freezes Fuse only when BlastRadius > 0 -- the
WeaponModifiers.Airburst label no longer decides anything (Q12-6).
PendingShot.BurstRadius is renamed BlastRadius and gains a Fuse field
that nothing reads yet; Step's Splash/Apply dispatch is unchanged.
No shipped weapon carries a blast radius or the Airburst label (Cut 12's
Probe4, reconfirmed against GameData/Aetheria.cc), so this is
behaviour-neutral on shipped content. Apply's fuse switch and deleting
Splash are Cut 12.4(b).
