Hazard volume

Ask: tick-damage | instant-kill | push-field.

Ownership

The hazard owns its gameplay volume and effect policy. Decorative art is not the oracle. Hit filtering remains compatible with hitbox-hurtbox / collision-layers; recovery or fall policy may delegate to fall-rules.

Contract

Publish:

• stable hazard_id
• authoritative volume shape/transform
• effect mode and project gameplay-clock policy
• target filters / immunity policy
• enter/stay/exit event identity
• cue/reference IDs used by presentation

For periodic effects, define the tick schedule from the project's gameplay clock and guarantee at-most-once application for one hazard/target/tick identity. Re-entering, pause/resume, streaming and rollback must not duplicate an already committed effect.
