-# Peptide News Aggregator
-
-A WordPress plugin that aggregates and displays the latest peptide research news from multiple sources, with built-in click analytics and trend reporting.
-
-## Features
-
-- **Multi-Source Fetching** — Pulls articles from RSS/Atom feeds (Google News, PubMed, custom) and NewsAPI.org
-- **Configurable Refresh** — Admin-controlled cron intervals from 15 minutes to daily
-- **Shortcode & Wigget** — `[peptide_news count="10"]` shortcode with card/compact/list layouts, plus a sidebar widget
-- **Click Analytics** — Tracks every outbound click with session tracking, device detection, and GDPR-friendly IP anonymization
-- **Analytics Dashboard** — Chart.js-powered admin dashboard with trend lines, device breakdown, source performance, and top articles
-- **REST API** — Full JSON API at `/wp-json/peptide-news/v1/` for external analytics tools
-- **Topic Analysis** — Aggregates clicks by article category to surface popular research topics
-- **CSV Export** — Export raw click data for offline analysis
-- **Dark Mode** — Automatically adapts to visitor's system theme preference
-- **Performance** — Transient caching, deduplication via SHA-256 hashing, and paginated DB queries
-
-## Requirements
-
-- WordPress 5.8+
-- PHP 7.4+
-- MySQL 5.7+ or MariaDB 10.3+
-
-## Installation
-
-1. Download or clone this repository into `wp-content/plugins/`:
-   ```bash
-   cd wp-content/plugins/
-   git clone https://github.com/peptiderepo/peptide-news-plugin.git
-   ```
-2. Activate the plugin in **Plugins → Installed Plugins**
-3. Navigate to **Peptide News → Settings** to configure your sources and fetch interval
-4. Click **Fetch Articles Now** to pull the first batch
-5. Add `[peptide_news]` to any page or post, or add the widget via **Appearance → Widgets**
-
-## Configuration
-
-### Settings (Peptide News → Settings)
-
-| Setting | Description | Default |
-|---------|-------------|---------|
-| Fetch Interval | How often to check for new articles | Twice daily |
-| Articles to Display | Number shown in shortcode/widget | 10 |
-| Search Keywords | Comma-separated terms for NewsAPI | peptide, peptides, BPC-157... |
-| RSS Feeds | One URL per line | Google News + PubMed |
-| NewsAPI Key | Optional API key from newsapi.org | — |
-| Data Retention | Days to keep analytics data | 365 |
-| Anonymize IPs | Zero out last IP octet (GDPR) | Enabled |
-
-### Shortcode Usage
-
-```
-[peptide_news]                        <!-- Default: 10 articles, card layout -->
-[peptide_news count="5"]              <!-- 5 articles -->
-[peptide_news count="8" layout="list"] <!-- List layout -->
-[peptide_news layout="compact"]       <!-- Compact layout (widget-style) -->
-```
-
-## REST API Endpoints
-
-All analytics endpoints require admin authentication (cookie or Application Password).
-
-| Method | Endpoint | Description |
-|--------|----------|-------------|
-| GET | `/wp-json/peptide-news/v1/articles` | List stored articles (public) |
-| GET | `/wp-json/peptide-news/v1/analytics/top` | Top articles by clicks |
-| GET | `/wp-json/peptide-news/v1/analytics/trends` | Daily click trend data |
-| GET | `/wp-json/peptide-news/v1/analytics/topics` | Popular topics/categories |
-| GET | `/wp-json/peptide-news/v1/analytics/devices` | Device breakdown |
-| GET | `/wp-json/peptide-news/v1/analytics/sources` | Source performance |
-| GET | `/wp-json/peptide-news/v1/analytics/export` | Raw click data for CSV |
-
-Query parameters: `start_date`, `end_date` (Y-m-d), `limit` (int).
-
-## Database Schema
-
-The plugin creates three custom tables on activation:
-
-- `wp_peptide_news_articles` — Stores all fetched article data (title, excerpt, content, author, thumbnail, categories, source, etc.)
-- `wp_peptide_news_clicks` — Raw click events with session, device, referrer data
-- `wp_peptide_news_daily_stats` — Pre-aggregated daily stats for fast dashboard queries
-
-All tables are dropped on plugin **uninstall** (not deactivation — data is preserved if you temporarily disable the plugin).
