+## V34 2026-03-20 17:30:00
+
+**Fix critical gaps: locale-gen, 32-bit multilib, network auto-detect, polkit**
+
+### Changes:
+- Fixed `src/install/modules/locale.sh`:
+  - Replaced `locale-gen` call with direct `localedef` (glibc provides localedef,
+    but locale-gen is a wrapper script that doesn't exist on from-scratch builds)
+  - Creates /usr/lib/locale directory before running localedef
+  - Graceful fallback if localedef fails
+- Fixed `configs/rc.d/dhcpcd`:
+  - Added network interface auto-detection via /sys/class/net/
+  - If configured NETWORK_INTERFACE doesn't exist, auto-detects first non-loopback,
+    non-wireless interface
+  - Prevents network failure if hardware assigns different interface name
+  - All references (start/stop/static IP) use auto-detected IFACE variable
+- Fixed `configs/rc.conf`:
+  - Changed FONT from "ter-v18n" to "" (empty = kernel default)
+  - ter-v18n requires terminus-font package which isn't in repos; was causing
+    setfont error at boot
+- Fixed `src/repos/extra/polkit/polkit.toml`:
+  - Changed session_tracking from libelogind to disabled
+  - No elogind package exists in repos; polkit still works for password prompts
+    via lxqt-policykit-agent, falls back to VT-based session detection
+- Enabled 32-bit multilib support:
+  - Changed `src/repos/core/gcc/gcc.toml` from --disable-multilib to --enable-multilib
+  - Created 14 new lib32 package definitions in gaming/ repo:
+    lib32-glibc, lib32-zlib, lib32-openssl, lib32-curl, lib32-expat,
+    lib32-ncurses, lib32-dbus, lib32-alsa-lib, lib32-freetype, lib32-fontconfig,
+    lib32-libxcb, lib32-libx11, lib32-mesa, lib32-nvidia
+  - All lib32 packages compile with CC="gcc -m32" and install to /usr/lib32
+  - Updated steam.toml to depend on lib32 packages (glibc, mesa, nvidia, X11, etc.)
+  - Updated wine.toml to depend on lib32 packages for WoW64 support
+- Fixed `tests/run-tests.sh`:
+  - Added re.DOTALL to dependency regex (multi-line arrays weren't being parsed)
+  - Added multilib tests: gcc --enable-multilib, 7 essential lib32 packages exist
+  - Added dhcpcd auto-detect test
+  - Total packages now 182 (up from 168)
+
+### Plan deviation/changes:
+- None
+
+### What is missing/needs polish:
+- lib32 packages untested on real hardware (need actual multilib GCC build first)
+- SHA256 checksums still placeholder
+- Terminus font package not created (optional, kernel default font is fine)
+
