-      # CROSS-COMPILE WORKAROUNDS — packages that fail aarch64 cross-compile
-      #
-      # These packages need NATIVE COMPILATION on the uConsole itself (aarch64).
-      # They cannot cross-compile from x86_64 for various reasons listed below.
-      # We work around them in the overlay until we set up distributed builds
-      # with the uConsole as a native aarch64 builder.
-      #
-      # ==== Cross-compile failures ====
-      #
-      # libcamera / libcamera-rpi / libpisp:
-      #   meta.platforms excludes aarch64. pipewire hard-depends on them in nixos-25.11.
-      #   Fix: empty meta.platforms + strip from pipewire buildInputs.
-      #
-      # gjs:
-      #   Need native display (GTK3/4 tests) for cross-compile configure.
-      #   Fix: meson -Dskip_gtk_tests=true.
-      #
-      # hyprland:
-      #   Qt6Quick missing from aarch64 qtdeclarative, breaks hyprland-qt-support.
-      #   Fix: wrapRuntimeDeps=false (Qt UI components disabled, WM still works).
-      #
-      # boost.mpi:
-      #   Boost.Build has no b2 architecture alternatives for ARM.
-      #   Fix: useMpi=false.
-      #
-      # perl-ldap (perlPackages.perlldap):
-      #   Module::Install requires Perl dynamic loading (Fcntl) which is
-      #   unavailable in cross-compiled Perl.
-      #   Fix: stripped from john.s propagatedBuildInputs.
-      #
-      # john (John the Ripper):
-      #   Indirectly affected — depends on perl-ldap for perl utility scripts.
-      #   Fix: perl-ldap stripped from propagatedBuildInputs (john still works,
-      #   just loses sha-dump.pl etc. LDAP support).
-      #
-      # gss (GNU Generic Security Service):
-      #   autogen.sh fails cross-compile. Pulled by mailutils → emacs-pgtk.
-      #   Fix: emacs withMailutils=false.
-      #
-      # emacs-pgtk:
-      #   Indirectly affected — depends on mailutils which depends on gss.
-      #   Fix: withMailutils=false (no mail/IMAP within emacs).
-      #
-      # qtquick3d (Qt6):
-      #   Qt::Quick not available in aarch64 cross-compile qtdeclarative.
-      #   cmake skips build, ninja has no install target.
-      #   Fix: removed js8call, switched wireshark → wireshark-cli.
-      #
-      # js8call:
-      #   REMOVED from system packages. Depends on Qt6 multimedia → qtquick3d.
-      #
-      # wireshark-qt:
-      #   SWITCHED to wireshark-cli. Same Qt6 multimedia → qtquick3d chain.
-      #
-# neovim:
-#   `libnlua0.so` built for aarch64, luajit (x86_64) tries to load it
-#   during codegen (preload_nlua.lua). No clean override option.
-#   Fix: remove from system packages + install via native build
-#   once uConsole is set up as remote builder.
-#
-# clamav:
-#   cmake try_run() + Rust proc-macro can't find native linker in
-#   cross-compile (cc crate uses cross CC, no cc in PATH for build
-#   scripts). Chain: clamav → system-path → etc → dbus → polkit.
-#   Fix: remove from system packages; clamscan available from server.
-
-#
-# ==== Remote builder setup (bidirectional) — TODO ====
-# To eliminate cross-compile exceptions, set up distributed builds:
-# 1. Create a dedicated `builder` user on both hosts (no shell, home=/var/empty)
-# 2. Add the same SSH key to both hosts (symmetric)
-# 3. On lazyworkhorse — `nix.buildMachines` pointing to uConsole for aarch64-linux
-# 4. On uConsole — `nix.buildMachines` pointing to lazyworkhorse for x86_64-linux
-# 5. Remove the uconsoleCrossOverlay workarounds above
-# 6. Nix auto-dispatches derivations by `system` — no per-package exceptions needed
-# Example buildMachines config:
-# Server dispatches aarch64 builds to uConsole (4 cores, less power):
-#   nix.buildMachines = [{
-#     hostName = "uConsole.local";
-#     systems = ["aarch64-linux"];
-#     maxJobs = 4;
-#     sshUser = "builder";
-#     sshKey = "/etc/ssh/builder_key";
-#   }];
-# uConsole dispatches x86_64 builds to server (36 cores, 256GB RAM):
-#   nix.buildMachines = [{
-#     hostName = "lazyworkhorse.net";
-#     port = 2424;
-#     systems = ["x86_64-linux"];
-#     maxJobs = 36;
-#     sshUser = "builder";
-#     sshKey = "/etc/ssh/builder_key";
-#   }];
-
-      # ==== How to build natively on uConsole ====
-      # To native-compile these on the uConsole:
-      # 1. Add uConsole as a remote builder (nix.buildMachines)
-      # 2. Set nix.extra-platforms = [ "aarch64-linux" ] on server
-      # 3. Remove the overlay workarounds below
-      # 4. Packages will auto-dispatch to uConsole for native builds
