+
+### Pending Hardware Tests
+
+| Platform | Status | Blocker |
+|----------|--------|---------|
+| Intel NUC | NOT TESTED | Requires physical hardware |
+| Raspberry Pi 5 (ARM64) | NOT TESTED | Requires ARM64 device + ARM64 ISO |
+| Generic x86_64 PC | PARTIAL | Dev server is the test platform |
+
+## Summary
+
+x86_64 platform fully validated on dev server. ARM64 and additional x86_64 hardware testing requires physical devices.
