I Lost a 3-Hour Debugging Session With Claude. So I Built a Fix.

It was a Friday afternoon. Going back and forth with Claude for almost three hours - tracking down a nasty async bug, refactoring a service layer, getting a solid explanation of why the race condition was happening in the first place. It wasn't just answers. It was a working session. The kind where the conversation itself becomes documentation - you can trace the thinking, see where things went wrong, read the clean explanation worth sharing with the team. Then the laptop died. No warning. Just black screen. When Chrome reopened, the tab was gone. Three hours of context, gone.
