Completes the #30719 restart-loop defenses. Defenses 1-2 (the
_HERMES_GATEWAY guard on `hermes gateway stop|restart` + terminal_tool,
and the cron-creation lifecycle filter) already landed on main, but two
gaps remained:
- The agent's `cronjob` model tool calls cron.jobs.create_job directly,
bypassing the hermes_cli.cron.cron_create CLI filter, so lifecycle
commands scheduled via the model tool were only blocked at execution
time (terminal_tool), not at creation. Moved the filter to a shared
cron/lifecycle_guard.py enforced at create_job — the single chokepoint
every job-creation path hits (CLI + model tool). Re-exported
_contains_gateway_lifecycle_command from hermes_cli.cron so
terminal_tool's import keeps working.
- No breaker for the auto-resume loop itself. Defenses 1-2 cover the
cron/CLI/terminal paths, but any other SIGTERM source (e.g. a raw
terminal("launchctl kickstart ai.hermes.gateway")) still triggers the
boot->auto-resume->re-run cycle. Added gateway/restart_loop_guard.py:
counts restart-interrupted boots in a rolling window (config
gateway.restart_loop_guard, default 3 boots / 60s) and skips
auto-resume for that boot once tripped. The gateway still comes up and
serves real inbound messages; it just stops replaying the session that
keeps killing it, putting a human back in the loop.
Also tightened the lifecycle regex over main's version: dropped
`hermes gateway start` (benign), required the gateway identifier on the
launchctl/systemctl branches (so `launchctl unload
ai.hermes.update-checker.plist` and `systemctl restart
hermes-meta.service` no longer false-positive), added the inverse
pkill token order, and fixed the binary-script bypass (decode with
errors='replace' instead of swallowing UnicodeDecodeError). The
create_job guard resolves relative script paths under HERMES_HOME/scripts
the same way the scheduler does, so a bare script name is scanned as the
file that actually runs.
Design and much of defense-2 originate from PR #33395 (@kshitijk4poor),
which itself salvaged #30728 (@SimoKiihamaki). Rebuilt against current
main since defenses 1-2 had already landed under different names.
Closes#30719.
