From the independent review of #210: - F1: processed/ and failed/ copies are created O_EXCL with -2,-3 suffixes via createUnique; same-named notes from different folders no longer replace one another's only surviving copy - F2: extract.TextInMax / readAllMax cap the bytes actually read (a note can grow after the Lstat); extract.TextIn gets a 64 MiB default cap - F3: a regular marker older than its note describes an earlier note of the same name; it no longer hides the new one (warn + remove); non-regular markers still count as done (no writes through links) - F4: the planted-marker-link test is renamed to what it observes Each has a test that fails without it; the read-cap test uses an endless reader that errors at 8 MiB so a regression fails instead of exhausting memory.
