The pre-push gate was failing on a layout that is actually correct. The
script sources ../../lib/common.sh, which is right for where it sits after
the flattening; the test's guard still hardcoded ../lib/common.sh from
before the move, so it reported drift against itself.
The prefix is now read out of the script under test, so the two cannot
desynchronise the next time the tree moves. Verified non-vacuous: rewriting
the script to ../../../lib/common.sh in a throwaway worktree still fails
the guard, and it now names the real prefix.
