+**Use Danish GNU mirror and add loopback disk setup script**
+
+### Changes:
+- Updated `toolchain/scripts/000a-download-sources.sh`:
+  - Switched all GNU package URLs to use `http://ftp.klid.dk/ftp/gnu` mirror
+    (faster from Denmark than ftp.gnu.org)
+  - Added `GNU_MIRROR` variable at top for easy mirror switching
+  - Non-GNU packages (kernel, mpfr, gmp, xz, zstd, perl, python, etc.) still
+    use their canonical upstream URLs
+- Added `toolchain/scripts/000-setup-disk.sh`:
+  - Creates a 50GB loopback ext4 filesystem at /opt/darkforge.img
+  - Mounts it at /mnt/darkforge — acts exactly like a real partition
+  - Uses fallocate for instant allocation (no slow dd)
+  - Includes remount instructions and fstab entry
+  - Safe: no repartitioning needed, uses free space on root
+- Updated `toolchain/scripts/000-env-setup.sh`:
+  - Improved error message to point users to 000-setup-disk.sh
+
+### Plan deviation/changes:
+- Using loopback file instead of a dedicated partition (user has no spare
+  partition but has 1.5TB free on root)
+
+### What is missing/needs polish:
+- None
