NebulaDatabase

public sealed class NebulaDatabase : IDisposable

The standalone orchestrator's database: SQLite (a file next to the orchestrator, the default for a local mesh) or PostgreSQL (for a deployed mesh), behind one ADO.NET surface. It holds three tables: nebula_control_plane (the control plane document, see SqlControlPlaneStorage) and nebula_entity (saved entities, see SqlPersistenceStore), and nebula_gateway_session (gateway admission claims), nebula_scope (scope-key claims), and shared_cache (write-once derived data workers share, see SqlSharedCacheStore). EnsureSchema creates them if they are missing; every SQL statement is written once and differs only in the few type names the two engines disagree on.
