HOLLOW SPIRAL — VANILLA MOB MODE / DAI 1.9.5

The Endless Survival experience intentionally defines no Hollow Spiral custom entity types.
Active room encounters, including Ruins, Castles, Witch Caverns, Volcanoes, Crypt Rituals and Ocean threats, summon ordinary minecraft:* entities.

DAI 1.9.5 native JSON entities, custom hitboxes and behavior_sequence AI are available to future Hollow Spiral revisions, but v0.3.7 does not force that migration because vanilla mob identity is currently intentional.

The Hollow Spiral companion resource pack may customize environmental blocks, UI/title presentation and namespaced assets while leaving vanilla entity render chains intact.
