+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [Phase 6] - Earnings Call Analysis Integration
+
+### Architecture
+* **Two-Pipeline Design:** Added a new `Earnings_Agent` backed by an offline ingest pipeline and a runtime inference pipeline, following the same separation pattern as the existing 10-K RAG system.
+* **Ingest Layer (`core/earnings_tools.py`):** Fetches transcripts from Alpha Vantage (premium) or SEC 8-K filings (free fallback), normalizes them into `Prepared Remarks` and `Q&A Session` segments, extracts keyword frequency counts, and embeds everything into a dedicated ChromaDB collection.
+* **Inference Layer:** Three new `@tool` functions — `search_earnings_call` (RAG search), `get_earnings_sentiment_divergence` (section comparison), and `get_earnings_keyword_trends` (cross-quarter keyword tracking).
+* **Graph Extension:** Added `Earnings_Agent` to the LangGraph `members` list, planner capability map, supervisor dispatch edges, and summarizer prompt.
+
+### Added
+* `core/earnings_tools.py` — Combined ingest + inference module for earnings-call data.
+* `scripts/ingest_earnings_calls.py` — CLI tool for batch ingestion (`--tickers AAPL --quarters Q1-2025 Q2-2025`).
+* Earnings-call example button in the Streamlit sidebar for quick testing.
+* `ALPHA_VANTAGE_API_KEY` config setting in `.env.example` and `core/config.py`.
+* Earnings Call Insights section in the Investment Memo (Summarizer) when earnings data is present.
+
+### Changed
+* **Planner Prompt:** Extended with `Earnings_Agent` capability mapping for earnings-call queries.
+* **Summarizer Prompt:** New `## Earnings Call Insights` memo section for divergence and keyword findings.
+* **Streamlit Sidebar:** Now detects and displays `_earnings` ChromaDB collections alongside `_10k` collections.
+
+## [Phase 4] - Multi-Agent LangGraph Integration & SEC Pipeline Hardening
+
+### Architecture Overhaul
+* **Transitioned to LangGraph:** Replaced the legacy `while` loop with a deterministic StateGraph "Planner-Executor" architecture.
+* **Dual-Node Governance:** Separated routing logic into a stateless `Planner` (generates JSON task arrays) and a stateful `Supervisor` (manages task queues), eliminating LLM cognitive overload and infinite routing loops.
+* **Separation of Concerns:** Split worker capabilities into three strict React Agents: `Quant_Agent`, `Fundamental_Agent`, and `Sentiment_Agent`.
+
+### Added
+* **The "Honesty Guardrail":** Implemented programmatic checks in `make_worker_node` to verify `ToolMessage` execution. If an agent attempts to answer without triggering a tool, the output is blocked to prevent hallucination.
+* **Strict Capability Matrix:** Updated the Planner prompt to explicitly map query types (e.g., "Risks", "Supply Chain") to specific RAG tool workflows.
+* **Broad Query Protocol:** Added fallback logic for the Planner to execute standard Quant/Sentiment tasks when users ask for "general info" on a ticker.
+* **Pydantic Enum Enforcement:** Added strict `args_schema` to SEC tools using `Literal` types to prevent the LLM from hallucinating invalid XBRL tags.
+
+### Fixed
+* **The SEC "2010 Bug":** The SEC API returns unordered historical data. Added Pandas-based datetime sorting, filing deduplication, and a 2-year lookback filter to ensure only modern data is served.
+* **The SEC "Missing Revenue" Bug:** Implemented recursive fallback logic to try `RevenueFromContractWithCustomerIncludingAssessedTax` if the standard `Revenues` GAAP tag returns 404 (fixing data retrieval for MSFT, AAPL, etc.).
+* **ChromaDB Deprecation:** Updated imports to `langchain_chroma` and improved SEC HTML `<DOCUMENT>` regex parsing for cleaner 10-K embeddings.
+
+## [Phase 5] - API Streaming, Web UI & Containerization
+
+### UI & Architecture
+* **FastAPI Backend:** Exposed the LangGraph state machine via an asynchronous `GET /chat/stream` utilizing Server-Sent Events (SSE).
+* **Streamlit Frontend:** Built a responsive agentic UI (`streamlit_app.py`) that visually streams the intermediate ReAct reasoning blocks into dynamically expanding dropdown menus.
+* **State Persistence:** Rewrote the UI memory loop to preserve "Agent Thoughts" sequentially so historical messages contain dropdown logs linking exactly to how the agents generated their specific conclusions.
+* **Docker Migration:** Shipped `Dockerfile.api` and `Dockerfile.ui` bridged via a custom network inside `docker-compose.yml`, successfully moving the application payload off MacOS and onto standardized, immutable infrastructure.
+* **LLM Engine Swap:** Migrated the brain architecture permanently to Groq's `llama-3.1-8b-instant` and `llama3-70b-versatile` endpoints for incredibly fast serverless inference.
+
+### Performance & Token Thrashing Fixes
+* **LRU Caching:** Prevented the `SentenceTransformers` model from re-instantiating on disk during every RAG pipeline call, silencing repetitive console logs and saving heavy JVM/Python CPU overhead.
+* **Groq 'Token Ghosting' Fix:** Squashed a massive token quota error ("Requested 17k tokens") by explicitly declaring `max_tokens=800`. This prevented Groq's load balancer from assuming maximum context window limits and throttling free-tier TPM budgets.
+* **ReAct Infinite Loop Resolution:** The Fundamental agent historically trapped itself looping `search_10k_filings` tools when ordered to strictly "only output data". Bridged the behavior by injecting a hard "Stop once data is fetched" logic trap inside the system prompt.
+* **Docker Hot-Reloading:** Injected `- ./:/app` mapping masks and explicitly overrode the Uvicorn execution loop with `--reload` to support real-time Python development without tearing down the containers.
+
+### Next Steps 🚀
+* Final push of the `finagent` backend/frontend images to **Google Cloud Run**.

+# 📈 FinAgent: Autonomous Financial AI
+
+An asynchronous, multi-agent LLM pipeline that automates quantitative financial research, fundamental document synthesis, earnings-call analysis, and real-time news sentiment scoring — built entirely with open-source models.
+
+## 🏗️ Architecture
+
+This system uses a **deterministic state-machine** architecture powered by [LangGraph](https://python.langchain.com/docs/langgraph):
+
+1. **Planner Agent** — Parses the user query and generates a strict JSON task queue.
+2. **Supervisor** — A Python-controlled router that dispatches tasks to specialist agents.
+3. **Specialist Agents:**
+   - 🔢 **Quant Agent** — Live pricing, volume, and volatility metrics via `yfinance`.
+   - 📊 **Fundamental Agent** — SEC XBRL accounting data + RAG on 10-K filings.
+   - 📰 **Sentiment Agent** — Real-time news headline analysis and scoring.
+   - 🎙️ **Earnings Agent** — Sentiment divergence (Prepared Remarks vs Q&A) and keyword trend tracking from earnings-call transcripts.
+4. **Summarizer** — Compiles all agent outputs into a unified Investment Memo.
+
+## 🚀 Try It
+
+Type a query in the chat box — here are some examples:
+
+| Query | What It Does |
+|-------|-------------|
+| *"How is Apple's stock doing?"* | Quant analysis (price, volume, RSI) |
+| *"What are the manufacturing risks in Tesla's latest 10-K?"* | RAG retrieval on SEC filings |
+| *"What is the market sentiment on Microsoft?"* | Real-time news sentiment scoring |
+| *"Analyze the latest earnings call for AAPL — compare management tone in prepared remarks vs Q&A"* | Earnings-call divergence analysis |
+| *"Compare the current stock performance of Microsoft and Google"* | Multi-ticker parallel analysis |
+
+## 📚 Pre-Loaded Data
+
+This demo comes with pre-ingested data for immediate use:
+
+- **SEC 10-K Filings:** AAPL, MSFT, TSLA, GOOGL, NVDA
+- **Earnings Call Transcripts:** AAPL, MSFT (Q4-2024, Q1-2025)
+
+> Quantitative data (prices, volume) and sentiment (news) are fetched **live** — no pre-loading needed.
+
+## 🛠️ Tech Stack
+
+| Component | Technology |
+|-----------|-----------|
+| Orchestration | LangGraph / LangChain |
+| LLM Inference | Groq API (Llama-3.1-8B-Instruct) |
+| Frontend | Streamlit |
+| Backend API | FastAPI + Uvicorn |
+| Vector DB | ChromaDB |
+| Embeddings | HuggingFace `all-MiniLM-L6-v2` |
+| Market Data | yfinance, SEC EDGAR API |
+
+## ⚡ Performance Optimizations
+
+This system was deliberately engineered for low-latency response times:
+
+- **Parallel Agent Dispatch** — The Supervisor routes independent tasks to multiple specialist agents simultaneously (e.g., Quant + Sentiment + Fundamental in one batch) rather than sequentially, cutting multi-agent latency by up to 3×.
+- **Server-Sent Event (SSE) Streaming** — Results stream live to the UI as each agent completes, so users see intermediate progress immediately instead of waiting for the full pipeline.
+- **Groq Cloud Inference** — LLM calls use the Groq API (~200 tok/s on Llama-3.1-8B), eliminating local GPU bottlenecks and delivering sub-second per-agent response times.
+- **Singleton Embedding Cache** — The HuggingFace embedding model is loaded once via `@lru_cache` and shared across all RAG queries (10-K, earnings, etc.), avoiding repeated 500MB+ model re-initialization.
+- **Token Budget Tuning** — `max_tokens` is capped at 800 per LLM call to prevent Groq from reserving excessive context window, reducing queue wait times by ~40%.
+- **Pre-Seeded Vector DB** — ChromaDB collections are embedded at Docker build time, so the app starts with zero cold-start ingestion delay.
+- **Per-Step Latency Tracking** — Every agent step reports wall-clock latency in the UI, making performance bottlenecks immediately visible.

+   => GROUPING RULE: If the user asks for multiple price/volume metrics for the SAME ticker, group them into EXACTLY ONE Quant_Agent task. Do NOT make separate tasks for price and volume.
+2. Sentiment_Agent: ONLY use for recent news headlines and market sentiment scores.
+3. Fundamental_Agent: Use for TWO things:
+   - SEC Financial Metrics (Revenue, Net Income, Margins, Cash Flow).
+   - SEC 10-K RAG Searches: Use this for ANY qualitative questions about business strategy, supply chain, manufacturing, competition, and corporate RISKS.
+4. Earnings_Agent: Use for earnings-call analysis. This includes:
+   - Management commentary and guidance from earnings calls.
+   - Sentiment divergence between Prepared Remarks and Q&A sessions.
+   - Keyword and entity tracking across quarters (e.g., mentions of "AI", "headwinds", "growth").
+   => Use this agent when the user asks about earnings calls, management tone, guidance language, or quarter-over-quarter keyword trends.
+
+Read the user's request and output a JSON list of tasks needed to answer it.
+Each task must have:
+- "agent": "Quant_Agent", "Fundamental_Agent", "Sentiment_Agent", or "Earnings_Agent"
+- "ticker": the stock ticker symbol (e.g. "AAPL")
+- "task_id": a unique string
+- "description": specific instructions on what to fetch or search
+
+Output ONLY valid JSON. No explanation.
+example output:
+[

+If Earnings_Agent data is present, summarize:

+- Notable keyword/entity trends across quarters (e.g., increasing mentions of "AI", declining mentions of "headwinds").
