+- Complete the first-run, view-target prewarm, cockpit-plates and floor-hold
+  browser harness renderer portability fixes contributed by Tom-Neverwinter.
+  macOS retains Metal; other platforms default to SwiftShader. Cockpit renderer
+  assertions and evidence labels follow the actual selected mode. Floor-hold
+  keeps its mesh and terrain assertions; software runs are not real-GPU evidence.
+  First-run QA now checks the existing attribution Escape-close/focus-return
+  behavior while preserving the launcher-underneath regression checks.
+

 - Datacenter and dam factories are available through scoped package exports with
   explicit context, overlay and render callbacks. The standalone app uses the
   same implementation and bundled datasets.
