swj.premkumar 97d13ee1ed 2026-01-15 (Phase 1: The Foundation) ... ### Added - **Hyper-Immutability (Physically Secured State)**: Implemented `FactLedger` (TypedDict) and `write_once_enforce` reducer in `agent_states.py` to cryptographically lock data reality. - Ledger is hashed (SHA-256) upon creation. - Wrapped in `MappingProxyType` to prevent any downstream agent from mutating the facts. - **The Data Registrar (Parallel Gatekeeper)**: Created `DataRegistrar` node (`tradingagents/agents/data_registrar.py`) that acts as the Single Source of Truth. - **Parallel I/O**: Fetches Price, Fundamentals, News, and Insider data concurrently (4x speedup over sequential). - **Partial Poisoning Guard**: Hard "Fail-Fast" if critical domains (Price, Fundamentals) are missing. - **Freshness Simulation**: Configurable `TRADING_MODE` (simulation/production) to allow rigorous testing without stale-data aborts. ### Fixed - **Hallucination Vectors (The Lobotomy)**: Removed ALL tool access from `Market`, `Social`, `News`, and `Fundamentals` analysts. - Analysts now consume exclusively from `FactLedger`. - Eliminated "Tool Use Loop" latency and potential for agents to fetch divergent data. - **Graph Wiring**: Refactored `setup.py` to route `START` -> `Data Registrar` -> `Market Analyst` -> Parallel Fan-Out.		2026-01-15 11:02:35 -06:00

regime_aware_signals.py	The **TradingAgents** system is a risk-managed, LLM-driven trading engine designed to execute trades based on validated truth, not hallucinations. It connects hierarchical LLM agents with deterministic safety gates to ensure that every trade is architecturally sound, factually correct, and risk-compliant.	2026-01-09 19:28:49 -06:00
