Both failure signatures match the hostile mutants F2 (the supervisor does not pass --out to the child or daemon) and F4 (no live-run refusal). A bisect file swap that was in place at the time was ruled out by timestamps, but a mutant left in the file would produce exactly these messages.\n\nNext step: make the results-beside-log message name the directory and whether results.json is missing or unparseable, so the next occurrence says which it was. Then find a check that asserts the file is restored after each mutant run.","author":{"url":"https://github.com/KyleAMathews","@type":"Person","name":"KyleAMathews"},"datePublished":"2026-11-14T05:02:40Z","url":"https://github.com/TanStack/oracles/issues/76"}
