 ### Executive Summary
-All 562 tests passing. ISO built successfully (816 MB). PRD → Docs → Code → Tests fully aligned.
+786 tests passing (0 failures, 16 VM skips). ISO built successfully (824 MB) and validated via automated QEMU boot test. Critical build bugs fixed in previous sessions (self-contained hooks, correct UKI cmdline, missing PRD hardening).

+## ISO Validation Results
+
+### Phase 0: Pre-flight (6/6 PASS)
+- ISO exists (825M)
+- SHA256 checksum valid
+- MD5 checksum valid
+- QEMU available
+- OVMF firmware found
+- VM disk created
+
+### Phase 1: Static Analysis (4/4 PASS, 1 SKIP)
+- ISO size reasonable (824MB)
+- ISO is valid bootable image (ISO 9660)
+- ISO contains EFI boot files (BOOTX64.EFI, GRUBX64.EFI)
+- ISO contains Debian installer/repository (INSTALL/, VMLINUZ, INITRD.GZ)
+- SKIP: Cannot mount ISO (needs root/fuse)
+
+### Phase 2: QEMU Boot Test (1/1 PASS, 1 SKIP)
+- UEFI firmware booted ISO successfully
+- SKIP: GRUB/Linux serial output (GRUB uses VGA; add `console=ttyS0` for serial)
