Capabilities
Runtime proof
renderer-initacceptedAwait createTowerShipLabController(), which awaits renderer.init() before exposing labController.
backend-is-webgpuacceptedCapture getMetrics().nativeWebGPU === true from the initialized controller.
mechanism-reachableacceptedLoad every physical mechanism route and reconcile the locked path against the selected runtime mode.
semantic-object-contractacceptedCapture node, socket, collider, destruction-group, and 24-oar inventories from root.userData.sculptRuntime.
aligned-readbackacceptedCapture RGBA8 render-target pixels with the controller-reported integer 256-byte row stride.
render-or-compute-workacceptedAccepted publishable release-bundle proves render-or-compute-work for webgpu-tower-ship-sculptor.

}Limitations
- Performance and GPU attribution remain NOT_CLAIMED unless a hardware performance lane is present.
- Promoted media are native-WebGPU correctness readbacks bound by the accepted release-bundle ledger.
