CreditService

creditservice is a minimal reference service that proves PhotonCloud can integrate vendor-specific quota and credit control with platform auth and gateway admission.

It is intentionally not a full billing product.

What this proves

• a vendor-specific credit or quota service can be built in-tree
• the service can authenticate against Photon IAM
• the service can participate in gateway and control-plane admission flows
• the service can persist state in Photon-supported backends

Supported scope

• quota checks
• credit reservations, commits, and releases
• tenant-aware auth integration
• gateway-facing admission control hooks

Explicit non-goals

• invoicing
• tax handling
• discounts and pricing catalogs
• finance-grade ledger completeness
• full metering platform ownership

Test expectation

The main proof should come from cluster-level VM validation in nix/test-cluster, not from expanding creditservice into a larger product surface.

Concrete proof path:

nix run ./nix/test-cluster#cluster -- fresh-smoke

That flow boots node06 with apigateway, nightlight, and creditservice, and validates that creditservice starts in the IAM-integrated cluster path.
