-# Finlytic Sentiment Service
-
-Finlytic Sentiment is a C# microservice dedicated to real-time AI sentiment analysis of financial news. It consumes pending news articles, runs FinBERT neural model evaluations, and aggregates sentiment scores at the asset (ISIN) and sector level.
-
----
-
-## Core Features & Architecture
-
-1. **FinBERT AI Integration**:
-   - Evaluates positive, negative, and neutral sentiment probabilities (`positiveProbability`, `negativeProbability`, `neutralProbability`, `compoundScore`).
-
-2. **ISIN & Sector Sentiment Aggregation**:
-   - Aggregates sentiment scores per financial asset (`IsinSentimentSummaryDto`) and sector (`SectorSentimentSummaryDto`).
-
-3. **Background Worker Engine**:
-   - Runs a 5-minute background loop (`SentimentBackgroundService`) polling pending articles, processing FinBERT evaluations, and publishing results over MQTT.
-
-4. **MQTT Event Channels**:
-   - Publishes updates to `finlytic/sentiment/result` and responds to RPC requests on `services/request/sentiment_GetArticle/#` and `services/request/sentiment_GetIsin/#`.
-
----
-
-## Feature Status
-
-### Implemented Features
-- [x] FinBERT AI Sentiment Evaluation Service (`IFinBertAnalyzerService`).
-- [x] Sentiment Storage & In-Memory Aggregation (`ISentimentStorageService`).
-- [x] 5-minute Background Worker loop (`SentimentBackgroundService`).
-- [x] Zero-Allocation MQTT serialization via `FinlyticJsonSerializerContext`.
-- [x] Pure Worker Service architecture (`Host.CreateApplicationBuilder`, no Kestrel HTTP server).
-
-### Planned Features
-- [ ] Historical sentiment trend charting (multi-month sentiment drift per asset).
-- [ ] Financial entity sentiment impact correlation model.
