API runtime PostgreSQL integration

What the API host verifies directly

The verified Property Management API host shows the canonical platform composition:

• use the reusable NGB.Api host library;
• register runtime with AddNgbRuntime();
• register PostgreSQL provider with AddNgbPostgres(connectionString);
• add vertical modules;
• add controllers, auth, health checks, and external links;
• build and run the ASP.NET Core app.

Why the split matters

NGB.Api

Provides the reusable host/web surface for ASP.NET Core concerns.

NGB.Runtime

Owns orchestration, document workflow, reporting flow, explainability surfaces, and business execution.

NGB.PostgreSql

Provides the concrete provider implementation that satisfies runtime persistence/reporting contracts.

Integration rule

The API host should compose the three layers. None of them should collapse into one giant project.
