Mirror the 3.3.5 client's own predicate on 1.12 data instead of pushing a placeholder false. The value is relative to the local player: the spellbook is folded into school masks of INTERRUPT_CAST spells and MOD_SILENCE spells (cached on Player::StatSignal), a cast is not interruptible when its PreventionType is not SILENCE or when the caster's immunity auras (effect / state / school / mechanic immunity) strip every mask, and the flag is never reported while the player knows no interrupt or silence at all. 1.12 differences, each documented in Spell::Interruptible: the vanilla server's interrupt effect also needs InterruptFlags 0x02 (channels: ChannelInterruptFlags 0x04), which silence ignores; SMSG_SPELL_START carries no immunity block, so creature_template interrupt immunity stays invisible; Feral Charge's interrupt lives on its triggered spell, so the capability walk follows one TRIGGER_SPELL hop. Verified in-game: a paladin's Holy Light reads false, flips to true while Divine Shield is up, and back to false when it drops. Also centralize SPELL_EFFECT_APPLY_AURA in Offsets.h (was local to Level.cpp).
