  "_comment": "Bash commands from docsync E2E runs and their mutations. {repo} is the fixture repo, {other} a directory outside it, {home} the fixture home. known_good: read-only forms the observer must accept. known_bad: forms it must keep rejecting. known_bad also keeps genuine model misses from PR gate runs as negative controls. The composed cat; cat of ship-docsync-failure 38984977679 (bash#12) reads only inside the fixture home with stderr discarded, so the grammar's 2>/dev/null widening (GSTA-49, Minder-approved) moves it to known_good_posix; its 2> to a file and 1>/dev/null mutations stay known_bad. The Bash grep of ship-docsync-missing-asset 38983306684 (bash#13) is a pure read inside the fixture home, so the shared read-only grammar (GSTA-49) accepts it in known_good_posix (the grammar resolves POSIX paths only and accepts nothing on Windows), as it does the Opus slips wc -l (39173752116) and ls with a glob (effort study t10); its tee, outside-path, recursive-credential and denied-glob mutations stay in known_bad. The narrow pwd/ls/cat/stat/sha256sum forms only read inside the fixture home, never a Claude config file but settings.json, nor actor state (GSTA-49 tightening; the config dir itself stays listable): cat {home}/cc/.claude.json and cat /etc/hostname are known_bad. Fable 5.1 (PR #3288 E2E 39186278010 and a focused rerun): the grammar join applies only to its own reads, so joined Git reads stayed known_bad until GSTA-57 (below); a trailing ; on a Git read is a harmless wrapper (known_good); a grep paged through sed -n with a line-range print script and an ls of the Claude config dir are known_good_posix; other sed scripts stay known_bad. Joined declared Git reads are accepted since ship-docsync-current runs 39347827595 and 39344306426 (GSTA-57), so git rev-parse HEAD; git status moves to known_good_posix while a joined Git write or bypass option stays known_bad.",
