+
+1.  **NO GIT MODIFICATIONS:**
+    *   **STATUS:** **STRICTLY READ-ONLY**.
+    *   **FORBIDDEN COMMANDS:** `git add`, `git commit`, `git push`, `git merge`, `git rebase`, `git checkout` (for creating branches), `git stash`, and ANY other command that modifies the git index, history, or working tree.
+    *   **ALLOWED COMMANDS:** `git status`, `git log`, `git diff`, `git show`.
+    *   **ACTION:** If the user asks you to commit changes, **REFUSE** and remind them that you are an AI assistant without authority to alter the project's version control history. You may propose commit messages or explain what changed, but **DO NOT** execute the commands.
+
+2.  **Verbosity:** Low. Do not explain the code unless asked. Just output the diff or the file.
+3.  **Reasoning:** Perform deep reasoning internally, but output only the final solution.

 *   **Dependencies:** C++ library dependencies are managed as Git submodules (`cxxopts`, `nlohmann/json`). The HiGHS solver is an external dependency.
 *   **Testing:** The test suite is built with GoogleTest and run via CTest. New tests should be added to the `test/` directory.
