# forgetest: the release acceptance tool's host-side proof.
#
#  - unit tests: campaign rules, fingerprints, artifact build/verify (the
#    release gate's decision, including the negative fixtures), runner +
#    HTTP API end to end with a fake catalog and a fake bench tool, the
#    suites replayed on the machine's own log lines, and the check that
#    every log phrase the cloud suite greps for is one the pinned cloud
#    app can log (it reads the app sources from the manifest cache)
#  - the source bundle of a release: which recipe of the image needs
#    source, which archive answers for it, and the refusal that stops a
#    release with source missing
#  - shared UI files: theme.css and the vendored Bootstrap the page
#    carries are byte-identical to forgectrl's at its pinned revision
#  - the extension key: the public key the image installs for the official
#    tier is byte-identical to the one the extension catalog publishes
#    (keys/forgefirm-ext.pub on its main branch)
#  - the catalog's address: EXTPKG_INDEX_URL in the pinned forgectrl's
#    src/extpkg.h is the catalog's latest-release download of the file its
#    tools/publish.py passes to gh release create; read, never requested
#    (every request of it is counted as a download)
#  - coverage lint: every source path of every component pinned by the
#    recipes must be selected by some catalog test's coverage globs or by a
#    host-tested row naming the host test that proves it (the tree manifest
#    is generated from the pins with git - no Yocto build); enforced: an
#    uncovered path fails the job (https://docs.forgefirm.org/developers/testing/).
