Combat Lab is the authored actor and encounter lab at @shared/scenes/combat_lab.scene.yaml. It provides pressure for active-pawn control, NPC actor control, patrol/perception, ranged and melee combat, defeat/respawn, encounter behavior, and world/owned-view presentation.

Use BulletSketch Play in Viewport or Run Standalone through the generic scene runner. Combat Lab has no dedicated application wrapper and no runtime bundle.

Automated proof includes session_ai_combat_lab_sample_tests, related combat, actor-control, and presentation suites, plus editor_standalone_combat_lab_runner_tests for the generic-runner workflow.

The scene and its dependencies live in the full shared workspace depot. Combat Lab is a development pressure surface, not a product application.
