Module data 

Data product filename, cache path, and archive URL catalog.

This module is sans-IO: it performs no network access, reads no files, and writes no cache entries. It only turns cataloged product inputs into canonical archive filenames, URLs, cache relative paths, and deterministic converted bytes for pure terrain ingestion.
