The no-change title test gets a real board under it — an empty folder is not a board and the loader rightly said so

The agent-written test inited BoardStore on a bare WriterFixture temp dir;
the fail-fast loader refuses that, so the test failed on its own branch
despite the reported green. Swapped to the file's own makeBoard() fixture.
