On "If in doubt, delete the uv.lock file"

Deleting lock files as a troubleshooting step is a band-aid that hides real dependency problems—and it trains you to ignore signals rather than read them. The uv ecosystem is still shaking out, and the fact that Python 3.15 compatibility is creating "occasional confusing errors" that require this workaround suggests tooling maturity issues that practitioners should know about before betting their workflows on it. If you're shipping libraries, skip uv.lock anyway, but if you're managing application dependencies, treating lock file deletion as a first resort means you're not actually solving anything—you're just resetting the board until the next mystery error shows up.
