- Document interactive shell vs /bin/sh in bare-os-shell man, handbook §9, kill(1), and shell-completion guide - Resolve kill %n and %% to synthetic PIDs via shellBackgroundJobs - Add disown builtin; jobs -p (pgid-only) and -l (pid column); set -o/+o to print errexit/nounset/pipefail/noglob - Expand completion-engine fallback flags for common utilities - Persist lines to /.bare/repl_history_<USER> when BARE_OS_REPL_HISTORY=1 and Fish REPL is off (repl-session + cli-readline) - Tests: kill job specs, set -o output, jobs -p
