The dashboard Profiles view showed "Gateway stopped" for a gateway that
is in fact running — while the sidebar status strip and `hermes gateway
status` (CLI) both correctly showed it running. Reported on v0.17.0
running the gateway + dashboard in one Docker container.
Root cause: three liveness surfaces with three detection strengths, all
reading the same `gateway.pid`:
- `hermes gateway status` -> find_gateway_pids() (process-table scan)
- sidebar /api/status -> get_running_pid() + gateway_state.json PID
fallback + health-URL probe
- Profiles view -> _check_gateway_running() = get_running_pid()
ONLY, no fallback
`get_running_pid()` short-circuits to None the moment the runtime lock
(`gateway.lock`) doesn't register as held by the *calling* process —
which is always true when the reader is a separate process from the
gateway (the dashboard is its own s6 service in the container), and also
for any launch-service-managed gateway that left a fresh
`gateway_state.json` but no live PID file. So the Profiles view alone
reported the live gateway as stopped.
Fix: give _check_gateway_running the same fallback the sidebar already
has — after the pid-file/lock check misses, validate the PID recorded in
that profile's gateway_state.json against the live process table via the
existing get_runtime_status_running_pid(). read_runtime_status() gains an
optional path arg so a profile's state file can be read without mutating
the process-global HERMES_HOME (preserving the contextvar-based profile
isolation the dashboard relies on). Backward compatible: every existing
caller passes no argument.
Tests: a regression test that fails pre-fix (live gateway, lock check
returns None -> must still report running) and a guard test that a
'stopped' state file is never reported running even with a live PID.
