A defaulted build argument answers a question the caller failed to answer. The build then succeeds against a base image, version or path nobody chose, and the mistake surfaces as wrong behaviour at runtime instead of a failed build. web-app-bridgy-fed shows the cost: its metadata declared python 3.14 while the Dockerfile default silently built against 3.12. Both look plausible, so nothing pointed at the drift. It and web-app-postmarks now take the base image from the same services declaration the rest of the role reads. The lint walks every tracked Dockerfile, template variants and paths outside roles/ included, which the existing ARG-scope check does not. A second assertion fails when the scan finds no Dockerfile at all, so the rule cannot pass vacuously if the walk ever breaks. Touching the two Dockerfiles brought their pre-existing narration under the comment lint; what carried substance moved into the file header.
