Under gateway.multiplex_profiles a turn running for a secondary profile P resolved
its live adapter by bare platform from runner.adapters — the DEFAULT profile's map —
so P's send_message tool calls (send/react/media on slack, matrix, wecom, buzz, ntfy,
every plugin platform), its "Gateway shutting down/restarted" and /update notices,
its /loop wakeups, and its Discord bot's unauthorized-slash operator alert all left
through the default bot (Telegram DMs landed in the user's chat with the other bot).
Every such door now resolves through the profile-aware, fail-closed resolver already
used by the inbound reply path (authz_mixin: _adapters_for_profile /
_authorization_adapter / _adapter_for_source): P's own adapter, or None → a clear
error, never the default bot.
- tools/send_message_senders.py::_live_adapter — resolve via
runner._authorization_adapter(platform, get_active_profile_name()); shared by
_send_via_adapter, _handle_react/unreact, media sends, matrix E2EE fast path and
the WeCom standalone sender.
- gateway/authz_mixin.py — extract _adapters_for_profile (the whole map, for relay-
aware resolve_delivery_transport callers); _authorization_adapter reuses it.
- gateway/run_shutdown.py — shutdown/restart notice for a running session uses the
session's source transport / agent:<profile>: key lane, never self.adapters.
- gateway/slash_commands.py + run_notifications.py — /restart and /update markers
persist `profile`; the restart notice, update result and update prompt resolve the
requester's own adapter (legacy markers fall back to the session_key lane).
/goal, /heartbeat, /approve, /deny confirmations use the source's own transport.
- gateway/slash_commands_goals.py + run_goals.py — /loop persists `profile` in its
route; the wakeup watcher scans every served profile's store under its own scope
(same shape as _handoff_watcher) and fires through that profile's adapter map.
- plugins/platforms/discord/adapter.py::_notify_unauthorized_slash — alert stays in
the owning profile (its adapters and its home channels).
- plugins/platforms/wecom/adapter.py::_standalone_send — via _live_adapter.
- docs: website/docs/user-guide/multi-profile-gateways.md (outbound identity).
Tests (red on base): tests/tools/test_send_message_multiplex_profile_adapter.py,
