Will It Vibe?Deprecated MAINTAINER instruction
Part of Architecture & Best Practices, which counts for 15% of the overall score. When this check fires it deducts 4 points from that category, once per scan, no matter how many places it turns up.
What it detects
MAINTAINER is deprecated. Use a LABEL (for example org.opencontainers.image.authors) so tooling can read the metadata consistently.
Why it matters
MAINTAINER is deprecated and Docker recommends against it. Tooling that reads image metadata looks at LABELs, not MAINTAINER, so the information is effectively invisible where it counts.
How to fix it
Replace MAINTAINER with a LABEL, using the standard key org.opencontainers.image.authors="name <email>". You can add related OCI labels (source, description) at the same time.
