팀 이직률에서 살아남는 시스템 구축

I have taken over codebases and had codebases taken from me. The experience in both directions has converged on one principle: a durable system communicates intent, not just implementation.

What durable looks like

Naming that explains purpose. Architecture that encodes constraints. Tests that document behavior, not implementation. The goal is a codebase where a newcomer can form a correct mental model in an afternoon.

The hardest part

Documentation rots. Comments lie. The only truthful documentation is the code itself — which is why naming and structure matter more than any README.
