 ## 2025-02-14 - [ASCII Fallback for Tables]
 **Learning:** Using Unicode box drawing characters enhances the CLI experience, but a robust ASCII fallback is crucial for CI environments and piped outputs.
 **Action:** Always implement a fallback mechanism (like checking `sys.stderr.isatty()`) when using rich text or Unicode symbols.

+## 2025-02-28 - [Interactive Restart]
+**Learning:** Reconstructing command arguments manually for process restarts is brittle and breaks forward compatibility.
+**Action:** When restarting a CLI tool with modified flags (e.g., removing `--dry-run`), filter `sys.argv` instead of rebuilding the argument list from parsed args.
