install from this checkout via RIG_INSTALL_SOURCE, assert what landed, a converging re-run proven by an empty diff, uninstall --all ending in the absence assert (! -e AND ! -L). test/install-lifecycle.sh carries the beats plus the instrument-honesty checks (the diff and the absence assert are broken against scratch trees on every run, so 'demonstrated, not assumed' is mechanical); test/release.sh gains the local channel's contract — dir, tarball, loud refusal, never a silent download fallback.
