# @landvex/infrastructure

Persistence adapters and infrastructure for LandveX domain.

## Architecture

```
Domain (interfaces) ← Infrastructure (adapters)
```

- **Domain defines** repository interfaces (WHAT)
- **Infrastructure implements** them (HOW)
- **Domain never depends** on infrastructure

## Repository Interfaces

| Interface | Purpose |
|-----------|---------|
| `FieldSessionRepository` | Store/retrieve field sessions |
| `MissionRepository` | Store/retrieve missions |
| `DecisionCaseRepository` | Store/retrieve decision cases |
| `ArtifactRegistry` | Register/find artifacts |
| `EventStore` | Append-only event log |
| `UnitOfWork` | Coordinate multiple repositories |

## In-Memory Adapters

For testing and development:

| Adapter | Data Structure |
|---------|---------------|
| `InMemoryFieldSessionRepository` | Map<string, FieldSession> |
| `InMemoryMissionRepository` | Map<string, Mission> |
| `InMemoryDecisionCaseRepository` | Map<string, DecisionCase> |
| `InMemoryArtifactRegistry` | Map<string, Artifact> |
| `InMemoryEventStore` | Array<DomainEvent> |
| `InMemoryUnitOfWork` | Coordinates all above |

## Future Adapters

| Adapter | Technology | Status |
|---------|-----------|--------|
| PostgreSQL repositories | PostgreSQL | Planned |
| S3 Artifact Registry | AWS S3 / Cloudflare R2 | Planned |
| Event Store | PostgreSQL / EventStoreDB | Planned |
