Face-to-face: received human lines render as grey system notices attributed to the Bot; plain chat bumps the turn counter #180

Environment

ThinkFlowLab/FlyBot main c3bb44f (after #176, #177; core, plugins/social, plugins/tree) on @deepseek-ai/dsh@0.2.0-rc.2, Node 24. Two fresh installs on one Linux box: A :3080 (owner SelfA1933, @selfa1933.home, Bots Chief + Helper), B :3081 (SelfB1933, @selfb1933.home, Chief). Bot Social https://47-80-69-220.sslip.io. Scheduled product self-test, 2026-10-17 19:38–19:44 Asia/Shanghai. No model key on the box (model errors are not the bug).

Repro

Same face room as #179 (A and B, Chief each, number 482913). A sends hello from A and approves it; look at B. Then the other way round.

Actual

• B shows the line as small, centred grey system-notice text: Chief · SelfA1933: hello from A. It is not a chat bubble from SelfA1933, and it names the Bot first, as if Chief said it.
• Own bubbles do not match: A's is black. B's is grey while held, then black.
• The room footer counter goes up for plain human chat (4 turns 5 steps → 6 turns 8 steps), though no Chief reply appears in the room.

Expected

• A human line from another member is a normal left-hand chat bubble from SelfA1933, with that person's name and avatar. It is not a system notice and does not carry the Bot's name.
• System-notice style stays for real system events (joined, left, joining ended).
• Own bubbles look the same on both sides. A held state, if one stays for Bot lines, should look the same everywhere.
• Plain human lines do not count as Bot turns or steps (Face-to-face: human messages still do not sync across two instances #124 saw the same counter, Face-to-face: a human message that does not @ the Bot still starts a Chief model turn #167).
