A while back I wrote about catching 3 bugs by making my AI review its own code as a skeptical stranger instead of trusting its own "done."
This time it happened again. Twice, in the same session, on two completely different kinds of work — and neither one was code.
First, a false alarm (so you know I don't cry wolf)
I was migrating my dev environment from one drive to another. Partway through, one folder was missing about 12,000 files. My assistant flagged it as a possible migration accident.
Turned out it wasn't. That folder was a virtual environment — a disposable toolbox rebuilt per project — and it was deliberately excluded from the move (it was sitting right there in .gitignore, with a note to rebuild it fresh at the new location). The files were missing because they were supposed to be missing; they were hardcoded to the old path and would've been dead weight anyway.
