A Green Frontend Pipeline Is Not the Same as a Safe Release

There is a particular kind of confidence that only a green CI pipeline can produce.

The pull request is open. Unit tests pass. Browser tests pass. The deployment preview looks normal. Nobody has reported a problem in Slack.

So the change gets merged.

Then Safari users cannot scroll a modal. Arabic text overlaps a button. A returning user is sent back to the login page after an MFA redirect. The AI assistant inserts a partial response into the wrong panel. Or the application works perfectly until the CDN serves a mixture of old JavaScript and new CSS.

None of these failures contradict the green pipeline.
