So that the project artifacts are traceable through the build process; in
order to (identify sources of variance) [Requirements Traceability, 5Ws]
This is called "provenance" in real metadata circles. [W3C PROV].

Because otherwise one has no idea what they are working with.
Because, for reproducibility, it's optimal to record all inputs as
Why would we be throwing this process knowledge away? dash-delimited
filenames to indicate a phantom ABI parameter?

This could be useful; we currently must use actual OS packaging to verify
per-file on-disk checksums (e.g. debsums).
e.g. we actually currently have no idea if the uncompressed archive files
differ from the checksummed archive, unless we re-download and compare with
an archive manifest;
because there is not yet a manifest containing
(path, checksum, [perms], [fsattrs])
