2.0 · The District

Every source has an address.

When a connector is enabled, it syncs on schedule, writes to the append-only event store, and cites every result back to the originating record. The District map groups 41 templates and narrative wards—not every block is a live sync.

5.0 · Trust

Built for control and accountability.

Private by default. Audited by design.

Permissions

Every query runs under a tenant context enforced by row-level security. API keys carry explicit scopes; users hold role-mapped permissions.

Privacy

Tenant data is isolated at the database layer, not just filtered in the app. Personal context stays per user.

Approvals

High-impact actions require human sign-off before execution.

Audit

Every query and result is recorded to an append-only audit log with actor, scope, and timestamps, queryable like any other table.
