# Staging Environment Implementation Summary

## Status: COMPLETE ✓

The Icarus Family Assistant now supports dual environments (staging vs prod) with environment-variable-driven database selection.

## Safety Features

1. **Default to Staging**: If `ENV` not set, defaults to `staging`
2. **Path Isolation**: Staging paths cannot overlap with prod paths
3. **No Auto-Seed in Prod**: Production never auto-seeded
4. **Startup Verification**: Logs ENV and paths on startup
5. **Explicit Opt-In**: `SEED_STAGING=1` required to seed

## Test Results

```bash
# Environment isolation
✓ Staging DB != Prod DB: True
✓ Staging Chroma != Prod Chroma: True
✓ Staging paths isolated: True

# Data seeding
✓ 4 documents ingested to staging ChromaDB
  - March Newsletter — Lincoln Elementary
  - Invoice #MDA-2026-0342 - Spring Ballet Session
  - Receipt #4582 - Buster Miller Wellness Exam
  - Soccer Schedule Update

# Query test
✓ Query "Is Friday a half-day?" returns results
  - Top result: March Newsletter (score: 0.612)
  - Found relevant documents
```

## Usage

### Quick Test
```bash
cd ~/hoffdesk-agents/services/family_assistant
ENV=staging python -m family_assistant.staging_data
ENV=staging python -c "
from family_assistant.family_brain import answer
result = answer('Is Friday a half-day?')
print(result['answer'])
"
```

### Production Service
```bash
sudo cp icarus.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable icarus
sudo systemctl start icarus
```

## Success Criteria Checklist

- [x] `ENV=staging` boots with Miller family test data
- [x] `ENV=prod` boots with empty DB (or existing prod data)
- [x] Database connections route to correct file
- [x] Test queries return Miller data in staging
- [x] Test queries return Hoffmann data (or nothing) in prod
- [x] Cannot accidentally write test data to prod

## Next Steps for Brain Query Development

The staging environment is now ready for:
1. Brain Query Interface development
2. Testing new RAG pipelines
3. Experimenting with prompt engineering
4. CI/CD integration with automated tests

All work can be done against the Miller family test data without risk to production Hoffmann data.
