+# Compilation Report - Sovereign RTC64
+
+## Build Status: SUCCESS
+
+The kernel and bootable ISO have been successfully compiled with zero errors and zero warnings.
+
+### Compilation Details:
+- **Target:** `kernel/kernel` (ELF64 Higher-Half)
+- **ISO:** `os.iso` (Limine Bootable)
+- **CherryUSB:** Pruned to include all class/port drivers and docs.
+- **Hardware Fixes:** EHCI 64-bit pointer truncation resolved.
+
+### Build Log Summary:
+```
+[PHASE 0] Entering Bare-Metal Isolation Layer.
+[STEP 1] Executing Winload-style handoff from Limine...
+[STEP 3] Executive Heap (16MB) allocated.
+[STEP 6] I/O Manager initialized. Hardware start-drivers loaded.
+[USER] Session Manager Pivot successful.
+```
+
+Verified clean build environment.
