 ## 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.

+## 2026-02-28 - Interactive Progress Bars for Suppressed Logs
+**Learning:** When users pass a '--quiet' flag to suppress verbose logging in a CLI app, long-running processes can appear frozen or broken, causing confusion.
+**Action:** When suppressing daily or detailed logs, implement a dynamic, single-line progress bar (guarded by checking if stdout is a TTY) to provide visual assurance that the process is still running.
