The download manifest lists public files and their

SHA-256 checksums. A ZIP-specific sidecar verifies the corresponding archive.

From the directory containing a ZIP and its sidecar, run the matching command,

for example:

sha256sum -c psych-stats-with-python-companion-v0.2.1.zip.sha256
sha256sum -c apa_article_lab_public_reader_release_v0.10.2.zip.sha256
