Research provenance now rides with the debate state, cache metadata, live payloads, and trace dumps so degraded research no longer masquerades as a normal sample. Bull/Bear/Manager nodes also return explicit guarded fallbacks on timeout or exception, which gives the graph a real node budget boundary without rewriting the bull/bear output shape or removing debate.\n\nConstraint: Must preserve bull/bear debate structure and output shape while adding provenance and node guards\nRejected: Skip bull/bear debate in compact mode | would trade away analysis quality before A/B evidence exists\nConfidence: high\nScope-risk: moderate\nReversibility: clean\nDirective: Treat research_status and data_quality as rollout gates; do not collapse degraded research back into normal success samples\nTested: python -m pytest tradingagents/tests/test_research_guard.py orchestrator/tests/test_llm_runner.py orchestrator/tests/test_live_mode.py web_dashboard/backend/tests/test_executors.py web_dashboard/backend/tests/test_services_migration.py web_dashboard/backend/tests/test_api_smoke.py -q; python -m compileall tradingagents/graph/setup.py tradingagents/agents/utils/agent_states.py tradingagents/graph/propagation.py orchestrator/llm_runner.py orchestrator/live_mode.py orchestrator/profile_stage_chain.py; python orchestrator/profile_stage_chain.py --ticker 600519.SS --date 2026-04-10 --provider anthropic --model MiniMax-M2.7-highspeed --base-url https://api.minimaxi.com/anthropic --selected-analysts market --analysis-prompt-style compact --timeout 45 --max-retries 0 --overall-timeout 120 --dump-raw-on-failure\nNot-tested: Full successful live-provider completion through Portfolio Manager after the post-research connection failure
This change set introduces a versioned result contract, shared config schema/loading, provider/data adapter seams, and a no-strategy application-service skeleton so the current research graph, orchestrator layer, and dashboard backend stop drifting further apart. It also keeps the earlier MiniMax compatibility and compact-prompt work aligned with the new contract shape and extends regression coverage so degradation, fallback, and service migration remain testable during the next phases.
Constraint: Must preserve existing FastAPI entrypoints and fallback behavior while introducing an application-service seam
Constraint: Must not turn application service into a new strategy or learning layer
Rejected: Full backend rewrite to service-only execution now | too risky before contract and fallback paths stabilize
Rejected: Leave provider/data/config logic distributed across scripts and endpoints | continues boundary drift and weakens verification
Confidence: high
Scope-risk: broad
Directive: Keep future application-service changes orchestration-only; move any scoring, signal fusion, or learning logic to orchestrator or tradingagents instead
Tested: python -m compileall orchestrator tradingagents web_dashboard/backend

Add effort parameter (high/medium/low) for Claude 4.5+ and 4.6 models,
consistent with OpenAI reasoning_effort and Google thinking_level.
Also add content normalization for Anthropic responses.
- Replace FinnHub with Alpha Vantage API in README documentation
- Implement comprehensive Alpha Vantage modules:
- Stock data (daily OHLCV with date filtering)
- Technical indicators (SMA, EMA, MACD, RSI, Bollinger Bands, ATR)
- Fundamental data (overview, balance sheet, cashflow, income statement)
- News and sentiment data with insider transactions
- Update news analyst tools to use ticker-based news search
- Integrate Alpha Vantage vendor methods into interface routing
- Maintain backward compatibility with existing vendor system
