hotfix

A production hotfix should include mandatory test execution on affected modules and add a minimal regression test if one is missing. It also requires providing explicit rollback instructions to ensure you can quickly revert the emergency patch if unexpected issues arise.

Documenting the root cause during a hotfix is necessary when the required code change is not obvious. This documentation preserves stability and confidence in the emergency correction by explaining why the minimal change effectively resolves the incident.

The best way to limit the blast radius of an urgent correction is to target the pinpointed bug fix across affected modules without feature additions or refactoring. Enforcing the smallest possible code change keeps the impact focused and preserves system stability.

You should not include refactoring or feature additions when shipping an emergency patch. The process strictly enforces a minimal change policy that targets only the broken code, ensuring the urgent production issue is corrected safely and quickly without scope creep.

Yes, a hotfix requires mandatory test execution on affected modules and adds a minimal regression test when coverage is missing. Even with the smallest possible code change, running these tests validates the correction and prevents future regressions in production.
