The store detail sheet now carries a data-source block for source.*
modules: publisher, upstream url, the terms in plain words, and any
attribution the operator has to carry with the output. It sits above
maintainers and above the install button, because it is a decision
input rather than a footnote.
The values are selectable: compliance notes get written by copying,
not retyping. A note names whose terms these are, so nobody reads them
as the module's own licence. Four guards, including that an empty
attribution renders no empty row.
