 - `ct record` verifies that `codetracer_python_recorder` is importable before launching the db backend and prints actionable guidance if the module is missing or broken.
 - Sudoku test-program datasets include intentionally invalid boards (e.g., examples #3 and #6) with duplicate digits inside a sub-grid; solvers should detect and report these gracefully.
 - `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.${system}.appimagePayload`, which layers the Rust binaries atop the dependency tree from `appimageDeps`, so the script just copies one derivation output into the AppDir.
+- `appimage-scripts/build_appimage2.sh` now consumes `packages.${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.
