+**Fix brace expansion failure in ISO build script causing missing directories**
+
+### Changes:
+- Fixed `src/iso/build-iso-arch.sh`: replaced all bash brace expansions in `mkdir -p`
+  with explicit individual `mkdir -p` calls. Brace expansion (`{a,b,c}`) was silently
+  not expanding when the script was invoked via `sudo bash`, causing critical directories
+  like `/var/lib/dpack/repos/` to never be created. This was the root cause of the
+  `iso.rootfs.repos` test failure — the repos `cp -a` had nowhere to copy into.
+  - Line 61: `${ISO_DIR}/{EFI/BOOT,LiveOS,boot}` → explicit mkdir calls
+  - Lines 67-70: `${ROOTFS}/{bin,boot,...}` and nested var/ structure → explicit calls
+- Previous V28 fixes (chmod a+rX, sudo test, debug logging) remain in place.
+
+### Plan deviation/changes:
+- None
+
+### What is missing/needs polish:
+- `qemu.kernel_boots` and `qemu.reaches_userspace` still expected failures — no real
+  kernel built yet (Phase 4 deliverable). ISO uses placeholder BOOTX64.EFI.
