I've applied a set of corrections, on Bash4LLM core, to reduce redundancy and make the flow more deterministic. Optimized safe_mkdir to eliminate superfluous calls to chmod, simplify temp file management by removing a redundant pre‑validation, remove repeated controls on ensure_run_tmpdir, unified internal standards but with backward compatibility, to correct duplications on providers management caused by a second redundant scan of provider modules, preserved diagnostic mode (CLI and environment variables). These are small jobs, but useful for clean and consistent runtime.
