How do you deploy a hotfix during a multi-stage canary release?
TESTS: if you decouple deploy from release with flags to patch without killing canary metrics. OUTLINE: dark-launch the fix to the canary cohort, preserve metrics, then jointly promote.
TESTS: whether you understand that Progressive Delivery and feature flags decouple deploy from release, letting you ship a hotfix without destroying ongoing canary signals or rolling back the whole release. OUTLINE: first, dark-launch the hotfix behind a separate flag and deploy it to the current canary cohort; second, continue collecting canary signals so the fix validates alongside the original change; third, jointly promote the combined release once you confirm no errors in production.
