Tasks 0.2-0.6 of the s6-overlay supervision plan. Locks the user-visible behavior we must preserve through the Phase 2 init- system swap: - test_main_invocation.py (Task 0.2): docker run <image> with no args, chat subcommand passthrough, bare executable passthrough, bash pattern, exit-code propagation - test_tui_passthrough.py (Task 0.3): TTY allocation via docker -t using the host's script(1) for a PTY - test_dashboard.py (Task 0.4): HERMES_DASHBOARD=1 opt-in, HERMES_DASHBOARD_PORT override - test_profile_gateway.py (Task 0.5): per-profile gateway start/stop and profile-delete-stops-gateway. Both marked xfail(strict=True) because the current tini image refuses gateway lifecycle commands inside the container; Phase 4 Task 4.3 flips them to passing. - test_zombie_reaping.py (Task 0.6): PID 1 reaps orphaned zombies. tini does this today; s6-overlay's /init must continue to.

"""Harness: PID 1 must reap orphaned zombie processes.

tini (current PID 1) reaps zombies via its built-in subreaper behavior.
|
|
s6-overlay's ``/init`` (Phase 2 PID 1) does the same. This invariant is
|
|
required for long-running containers spawning subprocesses (subagents,
|
|
dashboard, dynamic gateways) — otherwise the process table fills with
|
|
defunct entries and eventually exhausts the kernel PID space.
