The Rollback That the CDN Kept Serving for an Hour
The deploy was reverted in four minutes, and the incident lasted an hour, because the edge cache held the broken build and kept serving it to everyone the…

Reviewing the Silent Default That Hid the Missing Config
The loader fell back to a built-in value when the key was absent, so the service ran with the wrong setting for a week, and the startup log said the…

The Sandbox Checklist for Letting an Agent Touch Real Tools
The agent was given a shell and, eventually, a mistake. The boundary that made the mistake cheap was not the model's judgement but the sandbox: disposable…
