Single-layout design (no visible stage labels):
- Left: chat area. The case is the first 'assistant' message.
- Right: a text input that doubles as initial-argument writing in Phase 1
and a participant notepad in Phase 2.
Phases (implicit, driven by button clicks):
Phase 1 (entry): chatbot shows the case; right input is for initial
argument; chat input DISABLED.
Phase 2 (after Submit Initial confirm): host code calls
`core.perfect_answer.generate_session_artifacts` (around
15-30s blocking) to produce the per-session essay +
discussion plan. The plan is parsed and pinned into the
session cache. Each subsequent chat turn runs a manager
agent + main bot agent (see core.orchestrator). Right
input becomes a notepad; chat ENABLED.
Phase 3 (after End Session): chat input + notepad locked, done panel shown.
Per-message aha!/ugh. reactions: same as v3. Gradio's like/dislike buttons
swapped via EMOJI_SWAP_HEAD; clicks land in `logger.add_feedback`.
Two-agent flow per chat turn (post-Phase 1):
1. Manager agent classifies the turn (~2-4s blocking).
2. Host builds PLAN CONTROL block from the verdict.
3. Main bot streams its reply.
4. Host logs the turn (user_message + verdict + plan_control + bot reply
+ scratch + latencies).
