 - `appimage-scripts/build_appimage.sh` assumes a devshell: it invokes `nix build`/`nix eval` directly and runs `npm install`/`npx yarn`, so it needs host network access and the git worktree metadata that a pure derivation build lacks.
 - `appimage-scripts/build_appimage2.sh` now consumes `packages.${system}.appimagePayload`, which layers the Rust binaries atop the dependency tree from `appimageDeps`; both derivations pre-run `patchelf`, so the script only patches the locally built Nim binaries and bundled Ruby while everything else already targets `/lib64/ld-linux…` (or `/lib/ld-linux-aarch64.so.1`) with `\$ORIGIN/../lib` rpaths. The Nim outputs are provided via dedicated derivations (`appimageCtUnwrapped`, `appimageDbBackendRecord`, etc.) so we can pinpoint issues per artifact.
 - `flake.nix` sets `self.submodules = true`, so `nix build` automatically materializes the git submodules under `libs/`, which is required for the Nim derivations to see their dependencies.
+- Stylus-based frontend stylesheets now come from the `packages.${system}.appimageCss` derivation; `build_css.sh` simply copies that output, and `appimagePayload` pulls the same artifacts, so the AppDir no longer depends on ad-hoc `node_modules` during assembly.
+- `appimagePayload` now stages the launch scripts (`bin/ct`, `bin/ruby`, `AppRun`), config/resources, and the Ruby recorder submodule directly; `build_appimage2.sh` just handles impure steps (installing Ruby/Electron, copying `node_modules`, updating `frontend_bundle.js`, and calling `appimagetool`).
+- Third-party frontend assets that were previously symlinks into `node_modules` (`@exuanbo`, `golden-layout/dist`, `monaco-editor/min`, `mousetrap`, `vex-js`, `xterm`) are now materialized from `node-modules-derivation` inside `appimagePayload`, preventing broken symlinks when the payload is copied out of the Nix store.
