8.8c Who owns a red build?
| Situation | First owner |
|---|---|
| New test assertion failed after your PR | You (author) |
| Infra runner outage | Platform / DevOps shared |
| Flaky test without recent code change | Team — quarantine + ticket |
| Prod deploy health fail | On-call + immediate rollback habit |
Ownership is culture (Chapter 1) applied to the conveyor.
