Under gateway.multiplex_profiles the default gateway serves every profile, yet
four startup/status paths still reasoned from the wrong source:
* A secondary profile's API_SERVER_KEY (which the docs REQUIRE for /p/<profile>/
auth) auto-enabled api_server in that profile's config, so
_load_secondary_profile_config raised SecondaryPortBindingConfigError and the
whole profile was skipped. gateway/config_env.py::_enable_from_env now leaves
`enabled` alone for port-binding platforms while a multiplexer loads a
NON-default profile (home override + multiplex flag, the same signal
gateway.config uses for scoped reads); the credential still lands in extra so
the shared listener can authenticate the prefix. Default profile unchanged.
* "Is this profile served?" was re-derived from the default config.yaml plus
GATEWAY_MULTIPLEX_PROFILES as seen by the CLI process. `hermes -p coder ...`
loads coder's .env, so an env-only opt-in on the default profile was invisible
(guard never fired, status said stopped) and an allowlist edit flipped the
answer before the restart. named_profile_served_by_running_multiplexer now
reads the pid-verified default gateway_state.json served_profiles (written by
_record_served_profiles) first and falls back to config derivation only when
the key is absent. The record helpers live in hermes_cli/gateway_multiplex_served.py.
* The served-profile guard ran only inside `gateway run`. `hermes -p X gateway
start|install|restart` reached the service manager, whose unit then exited 78
forever (systemd parks it while the CLI prints "started"; launchd KeepAlive
respawns every 30 s). The service verbs now run the same guard up front
(exit 78, same message) and accept --force; the Desktop /api/gateway/start
route returns 409 for a served profile instead of spawning a doomed child.
* Status surfaces disagreed: `hermes -p coder status` said stopped, `hermes -p
coder cron status` said "cron jobs will NOT fire" while `cron list` said fine,
and the default `hermes status` never listed served profiles. Both now route
through the probe / the recorded served set. The -p/--profile matcher in
_scan_gateway_pids and gateway.status._command_line_belongs_to_profile compares
the flag token for equality (`-p ops` no longer claims -- or lets `gateway
stop` SIGTERM -- an `-p ops-2` gateway).
Docs: multi-profile-gateways.md now describes the start/install refusal, the
--force flags, the API_SERVER_KEY behaviour and the single default-home
gateway_state.json (the per-profile runtime_status.json claim was wrong).
