After the READY handshake, run_serve emits one TIERS status line (the web-dashboard expert-pyramid snapshot). cmd_chat never read it, so in interactive chat it surfaced as literal "TIERS 0 181 19275 0.00 ..." text prepended to the first response. Read and discard that one line after READY, matching how the other status frames are consumed. Chat-only; the HTTP serve path already drains it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
