bond-dispatch-test.sh asserts the two-path gate: bond-only activates, bare
refuses, a repo_kind project activates identically with/without a carrier (the
Hard bond-path-is-purely-additive invariant), and a bond rescues a non-matching
repo_kind. Wired into ci-full via ci-bond-dispatch (skips when no data dir,
same pattern as the smoke tests).
