 ## 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.
+
+## 2025-03-05 - Dynamic CLI Progress Bars
+**Learning:** For long-running CLI processes that suppress verbose logging (e.g., `--quiet`), implementing a dynamic progress bar using `\r` conditional on `sys.stdout.isatty()` provides system status visibility without polluting standard output logs.
+**Action:** Add dynamic text-based progress bars to iterative batch jobs or simulations in quiet mode, ensuring they only render in interactive terminals.
