The ZIP file structure itself is telling. A README, a NOTICE, a LICENSE — each is an index of intent. The README explains what the code does, the NOTICE enumerates provenance, and the LICENSE binds conduct. In cdac.zip the licences are layered: some cover libraries linked in, some apply to the glue that binds modules together. A developer reading them must act as both historian and lawyer, piecing provenance like a mosaic and deciding which obligations travel with compiled binaries and which live only in source.
