Pass 04 — Project, Area and Dataset API

Goal

Implement first real API slice.

Implement

• Project create/list/read.
• Area create/list/read for a project.
• Dataset registration endpoint and metadata placeholder contract.
• Validation for GeoJSON polygon areas.
• Contract tests with fixtures.

Constraints

• No frontend-only fake data assumptions.
• Invalid geometry must produce structured error.
• Dataset upload may be scaffolded, but response contracts must be stable.

Validation

• API tests.
• Contract fixture comparison where possible.
• Backend import.

Acceptance

• A client can create a project, add an area, register a dataset and retrieve them.
• Responses follow the documented envelope.
• Execution log updated.
