Review round 1 on PR #186: - The swap test's static note had the same title as the raced note, so the harness's "inside was read" floor passed without reading r.md (skipping r.md stayed green). The static note now has its own title. - An unreadable directory under wiki/ reaches the walk-error path, and swallowing that error stayed green. New test asserts the error. - The FIFO test now runs with and without a writer held open. - _index.md skip had no test; new test. - index.go: the double blank line left by removing readTitleAndCreated.
