Every failing sample below is the real generated shell script, with the stdout/exit-code mismatch that rejected it. Trial 0 runs at temperature 0, trials 1 and 2 at 0.7 — so a task passing 1/3 is a sampling-luck pass, not a reliable one. Models are ordered best first. Other technologies: C · Python · Bash · research · how to reproduce.
Setup and model serving are on the models index — including a script-free version using nothing but curl and a compiler; with a server running, this is the exact command that produced the samples below:
# Bash suite (8 easy + 3 hard tasks, 3 trials each)
python scripts/eval_bash.py --target <model> --set all --trials 3 \
--dump-failures results/failures
python scripts/eval_bash.py --target <model> --set brutal --trials 3 \
--dump-failures results/failures --json > results/<model>-brutal-bash.json

}Implement in bash: `backup_rotate <dir> <keep>`. In <dir>, deletes all but the <keep> newest files matching backup-*.tar.gz (newest = lexicographically greatest names). Prints each deleted file's name (not path), one per line, oldest first. Deletes nothing if there are <= <keep> backups (prints nothing). Reply with only a bash code block defining the function. No tests, no explanation.
