研究方向

The issue involves a non deterministic test failure in misc/output test.py related to progress output. Refer to the linked PR #1785 for context. The test assertion compares expected output, and the failure shows a mismatch in progress numbers and ANSI escape codes. Investigate the test file and the logic producing the output to identify the race condition or order dependency. Consider if the issue is resolved by the changes in PR #1785.
