Yellow Build
A build that completes but with warnings or unstable tests, signaling caution rather than a clean pass or hard failure.

What is Yellow Build?
A yellow build is the ambiguous middle ground between green and red: the build finished and didn't hard-fail, but it raised warnings or contained flaky, unstable, or newly quarantined tests that warrant caution. Yellow builds are a warning sign that quality signal is degrading, and left unaddressed they slide toward a suite no one trusts. The cure is to treat instability seriously—diagnose flaky tests rather than ignore them. Deterministic, self-healing suites keep builds decisively green or red, so the state of the codebase is never in doubt.
