- The /conductor/bin/git patch was a silent no-op if the shim's bytes drift from the exact pattern — now warns that laundering is NOT fixed. - The bashrc block documents why GSTACK_FREE_RETRY_FLAKY=1 deliberately overrides the runner's default-OFF contract on this sandbox, and how to undo it. - Test pins the guarded shm form (missing /dev/shm must not abort set -eu).
