 - `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` relies on `packages.${system}.appimageDeps` producing an AppDir-like tree (bin/, lib/), letting the script populate dependencies with a single `cp`.
+- `appimage-scripts/build_appimage2.sh` relies on `packages.${system}.appimageDeps` producing an AppDir-like tree (bin/, lib/) with transitive libs resolved via `lddtree`, so a single `cp` seeds the AppDir.
