Codex checks its work for you

Javi walks through a logging refactor and shows why Codex's self-verification is a step change: the model runs the app, finds the right session, and proves logs still flow. Takeaways: Codex can validate its work by running tests and launching the app. It excels at broad refactors that touch many files. The model can find session IDs and query tools on its own. Verification collapses a risky manual loop into minutes. When the agent can prove correctness, you can move faster with less risk.
