## Characterization test for the bull's damage reception. It pins the OBSERVABLE behaviour of
|
|
## take_sword_hit / apply_knock_up — pip loss, i-frame absorption, a single tagged death, and
|
|
## upward-only knock-up — before the WS2 slice reroutes them through DamageEvent, so the rewire can
|
|
## prove it changed nothing. When receive_damage(DamageEvent) lands, add a block that drives it and
|
|
## asserts the identical outcomes.
|
|
## Run: godot --headless --script tests/damage_pipeline_test.gd
