-        blank-chat hero, using the same confidence-gated detector the daily briefing uses. The selection happens
-        SERVER-side and the client renders it rather than recomputing. `signal: null` is the ordinary answer and means
-        the hero keeps its neutral greeting — never a fabricated opener. Two different causes produce that null and are
-        indistinguishable on the wire: nothing crossed the notability gate, or the account has turned proactive
-        suggestions off, in which case the detector does not run at all. The opener exists only to open the Coach, so it
-        is served only while the `coach` AI capability is available; otherwise the answer is the same neutral `signal:
-        null` and `ai` says why. Never refused for an AI reason. Shared analytics-read budget. Cookie or Bearer auth;
-        not delegable."
