 ## 2025-02-28 - Structured CLI Reports
 **Learning:** Dense numerical data in CLI output is hard to parse. Using ASCII box-drawing characters and alignment to create a "dashboard" or "invoice" style summary significantly improves readability and perceived quality.
 **Action:** When summarizing simulation or batch job results, always format the final report as a structured table or box rather than a list of print statements.

+## 2025-03-16 - Interactive CLI Progress Indicators
+**Learning:** For long-running CLI processes that suppress verbose logging (e.g., `--quiet` mode), users can become anxious and terminate the script prematurely if there is no visual feedback.
+**Action:** Implement a dynamic progress bar using `\r` and `flush=True` (conditional on `sys.stdout.isatty()`) to provide system status visibility without polluting standard output logs or breaking non-interactive environments.
