Close the remaining v0.8 posture bullet: flag enabled systemd units with
group/world-writable unit files (systemd_unit_writable, sid 100050) and
units whose ExecStart binary runs from a writable/unsafe path such as
/tmp, /dev/shm, /var/tmp, /home, or /run/user (systemd_exec_unsafe_path,
sid 100051).
- posture.systemd_findings/parse_systemctl_show/read_systemd_units, wired
into posture.run() behind the new posture_systemd config knob.
- read_systemd_units shells out to systemctl with timeouts and fails closed
on non-systemd hosts; the dashboard /api/posture surfaces findings for free.
- Unit tests for the parser and evaluator; TestRunIntegration patches the
new reader so run() never touches live systemctl.

Runbook 2 triggers, config TOML knob.

Red-team harness: every detector now has a named drill with an expected
signature/sid, shown by `sentinel-redteam --list`. Add the missing
`egress` drill (the one detector without one) — explicit-only, since it
is the sole drill that emits real outbound traffic. After firing, the
harness runs `enodia-sentinel check` and reports PASS/MISS per poll
detection, turning it into a shared regression check.
Add docs/RUNBOOKS.md: confirm/preserve/contain/recover playbooks for
reverse shells & egress, persistence, trojaned binaries / package
tampering, hidden listeners & rootkits, and sensor tampering — each tied
to the real signatures, sids, and commands. Linked from README and the
OPERATIONS alert workflow.
Both close the remaining smaller v0.8 roadmap items.
