## Usage Workflow

### Quick Start

```bash
cd provisioning

# Option 1: Interactive setup
typedialog --form .typedialog/vapora/forms/vapora-main-form.toml \
  --output config/runtime/vapora.custom.toml

# Option 2: Copy example
cp config/examples/vapora.solo.example.toml config/runtime/vapora.toml

# Option 3: Nickel composition
nickel export config/examples/vapora.multiuser.example.ncl > config/runtime/vapora.json

# Deploy
docker compose up -d
```

### Advanced Usage

```bash
# Custom Nickel composition
cat > config/runtime/custom.ncl << 'EOF'
let defaults = import "../../schemas/vapora/main.ncl" in
let mode = import "../../schemas/platform/defaults/deployment/enterprise.ncl" in

std.record.merge defaults {
  backend.port = 9001,
  llm_router.providers.ollama_enabled = true,
}
EOF

nickel export config/runtime/custom.ncl > config/runtime/vapora.json
```

## Integration Points

### With Docker Compose
- Mount config as volume: `./config/runtime/vapora.toml:/etc/vapora/vapora.toml`
- Services read from mounted configuration

### With Kubernetes
- Create ConfigMap: `kubectl create configmap vapora-config --from-file=config/runtime/vapora.toml`
- Mount in Pods
- Use Kustomize overlays for environment-specific customization

### With KCL Provisioning
- Existing `vapora-wrksp/` structure preserved
- Can link generated config: `ln -s ../config/runtime/vapora.toml ./vapora-wrksp/config.toml`
- Provisioning workflows can read configuration

## Validation

### TOML Files
```bash
toml-cli validate config/runtime/vapora.toml
```

### Nickel Files
```bash
nickel typecheck config/examples/vapora.solo.example.ncl
nickel export config/examples/vapora.solo.example.ncl | jq .
```

### Configuration Structure
- All TOML examples are valid and ready to use
- All Nickel schemas are well-typed and composable
- All output is valid JSON-compatible configuration

## File Statistics

| Category | Count | Lines |
|----------|-------|-------|
| Forms (typedialog) | 4 | 600+ |
| Schemas (Nickel) | 8 | 800+ |
| Examples (TOML) | 3 | 550+ |
| Examples (Nickel) | 3 | 90+ |

## Standards Applied

### Nickel Guidelines (nickel.md)
✅ Schema-first record definition
✅ Gradual typing strategy
✅ Design by contract (with defaults)
✅ Function composition (helpers)
✅ Lazy evaluation awareness
✅ Mergeable records
✅ Metadata-driven documentation
✅ Standard library usage
✅ JSON output validation
✅ Test-driven configuration

### typedialog Standards
✅ TOML form definitions
✅ Field validation (ranges, required)
✅ Nickel path mapping
✅ Interactive prompts and help text
✅ Structured forms with fragments
✅ Environment variable compatibility

## Next Steps for Users

1. **Choose deployment mode** - Solo, Multiuser, or Enterprise
2. **Generate configuration** - Use interactive form or copy example
3. **Customize** - Edit for your environment (domains, budgets, providers)
4. **Validate** - Run validation commands
5. **Deploy** - Use Docker Compose, Kubernetes, or KCL provisioning
6. **Monitor** - Check metrics at `/metrics` endpoint

## Limitations & Assumptions

### Not Implemented
- ❌ Automatic TLS certificate generation (must provide certs)
- ❌ LLM provider credential validation (must test separately)
- ❌ Kubernetes manifest generation (separate step needed)
- ❌ Database migration automation
- ❌ Secret management integration (use external secret manager)

### Assumptions Made
- ✅ SurrealDB available at configured URL
- ✅ NATS cluster available if enabled
- ✅ Storage paths writable by service user
- ✅ Network connectivity between services
- ✅ LLM provider API keys set via environment

## Architecture Decisions

1. **Layered Approach** - Forms → Schemas → Configs (separation of concerns)
2. **Nickel for Composition** - Enables merging and customization
3. **Deployment Profiles** - Pre-built defaults for common scenarios
4. **Fragment Forms** - Modular form structure for maintainability
5. **TOML Output** - Simple, portable, widely-supported format
6. **Helper Functions** - Reusable composition utilities

## Testing Verification

All configuration examples have been:
- ✅ Syntactically validated (TOML, Nickel)
- ✅ Schema-checked (types and contracts)
- ✅ Logically verified (cross-referenced with VAPORA architecture)
- ✅ Integration tested (expected field structure)

## Documentation Quality

- ✅ README.md - 700+ lines, comprehensive guide
- ✅ integration.md - Workflow and deployment examples
- ✅ config/examples/README.md - Configuration reference
- ✅ Inline documentation - All fields documented with descriptions
- ✅ Examples - 6 complete examples (solo, multiuser, enterprise in both TOML and Nickel)

## Maintainability

- ✅ Clear directory structure
- ✅ Modular form fragments
- ✅ Reusable Nickel helpers
- ✅ Composable schemas
- ✅ Environment variable overrides
- ✅ Self-contained deployment profiles

---

## Summary
