# Latent: Reddit Ingestor (Tier 5)

This component monitors social signals ("The Noise") to detect latent safety issues before they appear in clinical literature.

## Scope (Week 2)
- **Source:** Reddit API (PRAW)
- **Targets:** r/Ozempic, r/Mounjaro, r/Semaglutide, r/Wegovy
- **Method:** Fetches `new` posts, filters by severity keywords (`paralysis`, `er`, `hospital`), and extracts structured assertions.

## Setup

1. **Credentials:**
   You need a Reddit App (Script type). Go to [https://www.reddit.com/prefs/apps](https://www.reddit.com/prefs/apps).
   
   Create a `.env` file in `latent/ingest-reddit/`:
   ```env
   REDDIT_CLIENT_ID=your_id_here
   REDDIT_CLIENT_SECRET=your_secret_here
   REDDIT_USER_AGENT=LatentBot/0.1
   
   # Optional: For real extraction (otherwise uses Regex Mock)
   OPENAI_API_KEY=sk-...
   ```

2. **Install:**
   ```bash
   pip install -r requirements.txt
   ```

3. **Run:**
   ```bash
   python main.py
   ```

## Output
Generates `tier5_social_graph.jsonl`.
Entries look like:
```json
{
  "subject": "semaglutide",
  "predicate": "side_effect",
  "object": "gastroparesis",
  "source_class": 5,
  "source_metadata": {
    "type": "reddit_post",
    "subreddit": "Ozempic",
    "severity": "high"
  }
}
```

## Privacy Note
Author names are hashed (`hash(post["author"])`) before storage to provide basic anonymization while allowing for "Cluster" analysis (detecting if one user is spamming vs many unique users).
