Sync ThreadPoolExecutor doesn't truly parallelize inside LangGraph nodes.
Switched to async functions with asyncio.to_thread() + asyncio.gather() —
the same pattern that works for the parallel analyst node.
Result: Research (Bull+Bear) and Risk (Agg+Con+Neu) now run concurrently.
Total analysis time reduced from ~450s to ~280s (~38% faster).

Use sync functions with pool.submit() instead of async+run_in_executor
to avoid potential asyncio event-loop interaction issues with LangGraph.
Added timing logs to diagnose parallelism.

LangGraph state proxies serialize concurrent dict access, forcing
threads to run sequentially. Fix by snapshotting needed fields into
plain dicts before dispatching to ThreadPoolExecutor — same pattern
used by the working parallel analysts node.

Run Bull+Bear researchers concurrently and all 3 risk analysts
(Aggressive/Conservative/Neutral) concurrently instead of sequentially.
With max_debate_rounds=1, there's no back-and-forth so parallel execution
is safe. Sequential mode is completely unchanged.

The final decision block set all agents to "completed" in buf but never
emitted agent_update SSE events for them. This left Risk stage dots as
cyan (active) and Decision dot as gray on the UI. Now emits agent_update
for any agents not yet shown as completed before the decision event.

With stream_mode="values", each chunk contains the full accumulated state.
The debate and risk sections were checking data fields (bull/bear history,
aggressive/conservative/neutral history) without guarding against re-processing,
causing completed agents to be reset to "in_progress" on every subsequent
chunk. This made agent and report counts appear stuck at 5/12 and 4/7.
Fix: move the _emitted flag guard to the outer if-block so the entire
section is skipped once its event has been emitted.

Remove verbose debug prints added during parallel analysts development.
Fix reports showing 4/7 by updating buf.report_sections for investment_plan,
trader_investment_plan, and final_trade_decision (previously only analyst
reports were tracked).

Run all 4 analysts (Market, Social, News, Fundamentals) concurrently
using asyncio.gather instead of sequentially. Each analyst gets its own
isolated message state and tool-calling loop. Cuts analyst phase from
~8-9 min to ~2-3 min (total analysis from ~11 min to ~4-5 min).

- Replace global update_research_team_status() with local buf calls
(was updating CLI's global buffer, not analysis-specific one)
- Add replay buffer: all events stored in memory per analysis
- Support ?last_event=N query param for reconnection replay
- Send event IDs so browser can track position
- Mark analysis as done so replay works after completion

Railway kills idle connections after ~30s. During long LLM calls
between agent stages, the SSE stream goes silent and gets dropped.
Now sends heartbeat events every 15s to keep the connection alive.

Swap Chainlit chatbot UI for a minimal FastAPI service with:
- POST /analyze to start analysis
- GET /analyze/{id}/stream for SSE progress events
- GET /health for Railway healthcheck

Replaces the barebones web UI with one that mirrors the CLI:
- Agent status table with team/agent/status tracking
- Reuses CLI's MessageBuffer, update_analyst_statuses, classify_message_type
- Shows full debate transcripts (Bull/Bear, Risk team)
- Live stats (LLM calls, tokens, elapsed time)
- Collapsible Steps for each phase with full report content

The old model ID claude-sonnet-4-5-20241022 returns 404. Updated to
the current claude-sonnet-4-6 for the deep thinking model.

Chainlit 2.9.6 rejects the manually-created config.toml as outdated.
Let it generate its own at runtime.

Adds a Chainlit-based web interface that wraps TradingAgentsGraph,
streaming analyst reports, research debates, and final decisions
to the browser in real-time. Configured for Anthropic Claude models.
