Summary

• Add an opt-in macOS interaction host that runs the real Studio workbench against a disposable scene project.
• Run the same YAML with adastudio-flow or the AdaMCP tool editor.ui.run_flow. Resolve rendered gizmo anchors and AdaUI selectors, then dispatch through the window input queue.
• Cover X-axis gizmo drag, one-step undo, mid-gesture cancellation, hierarchy reparenting, and cycle rejection. Return a step trace and a screenshot when available.
• Fix the Swift and Metal startup blockers encountered while building and launching the host.

Validation

Every failing check in the local validation reproduced on main.

• Swift 6.3.2 built the macOS host. The same 14-step fixture passed through CLI and AdaMCP. A deliberately wrong transform failed at step 4. Closing MCP stdin shut the host down cleanly.
• The WebGPU distance-field and Hybrid IBL/SSR suites passed. The full run reported 24 issues across 326 tests. The control reproduced all 24 diagnostics and all 21 failing PNGs byte for byte. The control used the renderer, tests, and goldens from main at 5d811820a and needed the one-line Swift exclusivity fix to build.
• The scoped comparison reproduced all 178 SwiftLint diagnostics, five Ruff B023 findings, and two secret-scanner matches on main. The scanner matches were unchanged public Git revision pins for AdaMCP and SwiftTerm.

Run the fixture.
