Reproduce the report with Python 3.11, Logging, and colorlog under PM2, then compare how normal and error output is classified. The issue names no source file, entry point, or test, so first trace the PM2 log-handling path from the reported command-line setup. Done means normal logs are no longer displayed as errors and the behavior is covered by a regression test.
