"""A stand-in for the GitHub CLI's `gh api`, for tests/test_publish_release.py and
tests/test_release_workflow.py. Serves the releases in $FAKEGH_RELEASES (a JSON list,
drafts included) and the tags in $FAKEGH_TAGS (space-separated); an upload's body is
written to $FAKEGH_UPLOAD. Every call is appended to $FAKEGH_LOG as a JSON line.
Anything else fails; `gh release upload` works only when a release-workflow test
explicitly sets FAKEGH_ALLOW_RELEASE_UPLOAD=1. POST .../releases (release.yml's draft step) answers as release
$FAKEGH_NEW_ID (default 9001) without adding it to the listing, like GitHub's list
lagging a fresh draft. With jq installed, --jq filters a response the way gh does
(raw strings, compact JSON)."""
