Walkthrough

Untagged agent image references now receive the subject version before Compose rendering. Explicit tags, digests, empty values, and registry ports retain their existing behavior. Table-driven tests cover these cases.

Poem

A rabbit tags images with care,
Adding versions only where bare.
Ports and digests stay in place,
Tests hop through each edge-case space.
Compose renders neat and bright!
