NightLight

nightlight is UltraCloud's supported metrics ingestion and query service for the edge bundle.

Supported product shape

NightLight is supported as a single-node WAL/snapshot service; replicated HA metrics storage is not part of the product contract.

Retention is instance-wide and controlled by retention_days, the WAL, and periodic snapshots.
The supported proof scope is nix run ./nix/test-cluster#cluster -- fresh-matrix, which validates the shipped HTTP and gRPC query surface on the gateway node.
Shared deployments should put authentication and exposure policy in front of NightLight through APIGateway or another authenticated front door.

NightLight does not provide a hard multi-tenant security boundary inside the process.

One NightLight instance per environment or tenant boundary is the recommended shape when strong separation is needed.
Labels and caller discipline can partition data operationally, but they are not a product-grade authorization boundary.
Per-tenant retention or quota enforcement is not part of the current contract.
