Bring up adapters for every profile the gateway serves, not just the active
one. Keeps self.adapters as the default/active profile's map (the ~93 existing
self.adapters[...] sites are untouched) and adds secondary profiles under
self._profile_adapters[profile][platform].
- _start_secondary_profile_adapters loops profiles_to_serve(multiplex=True),
skips the active profile (handled by the primary startup loop), and for each
other profile loads its gateway config and creates+connects its enabled
adapters under that profile's _profile_runtime_scope (home + secret scope).
- Each secondary adapter gets _make_profile_message_handler(profile): stamps
source.profile (when unset) before delegating to the shared _handle_message,
so the agent turn and session key resolve to that profile.
- Same-platform credential-conflict detection: _adapter_credential_fingerprint
hashes the adapter's bot token (salted, truncated — never logs the token);
two profiles claiming the same (platform, token) refuse the duplicate with a
clear error naming both, since one token can't be polled twice.
- Port-binding hard-error: a SECONDARY profile that enables a port-binding
platform (webhook, api_server, msgraph_webhook, feishu, wecom_callback,
bluebubbles, sms) is a config error and aborts startup via MultiplexConfigError
— the default profile owns the single shared HTTP listener and serves every
profile through the /p/<profile>/ prefix, so a second bind can only collide.
Distinct from a transient connect failure (which logs + stays alive to retry):
a config error writes gateway_state=startup_failed and exits cleanly with an
actionable message (names the profile, the platform, and the fix). There is no
valid reason to bind a second port once you've opted into a multiplexer.
- Shutdown tears down secondary adapters alongside the primary ones.
- Defensive getattr guards keep partial-construction unit tests (stop(),
_run_agent on bare instances) working.
No-op when multiplex_profiles is off (self._profile_adapters stays empty).
Tests: fingerprint stability/log-safety/distinctness, profile message-handler
stamping (and not overriding an already-stamped source), port-binding hard-error
raises + names the profile/platform, non-binding platform is not rejected, and
the guard set covers every TCP-binding adapter.
