+# One-off, manually dispatched: prove the published x64 DMG on REAL Intel mac
+# hardware (the arm64 build host can't; Rosetta lacks AVX so the bundled Bun
+# claude CLI is untestable there). Downloads the live release asset, checks
+# every binary's arch, runs the bundled python + CLI, then boots the whole app
+# and polls backend health.
