How I think
Principles
Tests should block bad code. Not report it after it ships.
Quality starts at the architecture review. Not the pull request.
A framework nobody uses is worthless. Clean, maintainable code engineers actually want to work with.
AI writes code faster than humans. That means more subtle bugs, not fewer. Someone has to catch them.
Zero coverage is a starting point. Not an excuse.
