# 🕵️ Trace — "Your Digital Footprint"
> Meta OpenEnv Hackathon 2026 | Team Submission

**Trace** is a privacy-centric, multi-agent RL environment that builds a dynamic *Semantic World Model* of a user's fragmented digital life — without centralizing data.

## Themes Addressed
| Theme | Coverage |
|-------|----------|
| **Theme #2** – Long-Horizon Planning & Instruction Following | Primary — federated multi-step retrieval across years of data |
| **Theme #1** – Multi-Agent Interactions | Secondary — planner, retriever, verifier, memory agents |
| **Theme #4** – Self-Improvement | Tertiary — agents learn from past executions, refine strategies |
| **Sub-theme: Scale AI** | Non-code long-horizon business/personal workflows |
| **Sub-theme: Patronus AI** | Consumer workflows with schema drift (Gmail/Drive APIs change) |

## Quick Start

```bash
# 1. Install dependencies
pip install -r requirements.txt

# 2. Bootstrap OpenEnv environment
cd environments/trace_env
openenv init   # or run: uvicorn app:app --reload

# 3. Run training script (Google Colab friendly)
cd training
python train_grpo.py --config ../configs/grpo_config.yaml

# 4. Evaluate
python scripts/evaluate.py --env-url http://localhost:8000
```

## HuggingFace Deployment

### Required Secrets

Set these in your HF Space settings → **Repository secrets**:

| Secret Name | Source File | Description |
|-------------|------------|-------------|
| `GCP_CREDENTIALS_B64` | `credentials.json` | Google Cloud OAuth client credentials |
| `GMAIL_TOKEN_B64` | `token_gmail.pkl` | Gmail API OAuth token (base64-encoded pickle) |
| `SHEETS_TOKEN_B64` | `token_sheets.pkl` | Sheets API OAuth token (base64-encoded pickle) |
| `SHEETS_LEDGER_ID` | `.ledger_id` | (Optional) Google Sheet ID for the financial ledger |

Generate all base64 secrets at once:
```bash
python3 generate_secrets.py   # → creates hf_secrets.txt with all values
```

### Live Dashboard

Visit `/dashboard` on your deployed Space to see a **live financial transaction dashboard** populated from Gmail. The endpoint:
1. Searches Gmail for financial emails (last 180 days)
2. Parses transactions (vendor, category, amounts)
3. Renders an interactive HTML dashboard

Results are cached for 10 minutes. Force refresh with `/dashboard?refresh=true`.
