API-only Phoenix 1.8 project for cloud-ops, inventory, billing, and provisioning sagas. Validates arcadia JWTs via shared Guardian secret (verify-only; arcadia-app remains the issuer). Deps beyond default Phoenix: guardian, cors_plug, oban, req. Postgres on local port 5433 per arcadia stack convention. Endpoint runs on :4005. Endpoints: - GET /api/health — public, returns service identifier - GET /api/v1/inventory — auth-gated, returns empty list (phase 0 stub) Oban configured with the queues phase 1+ will need: provisioning / cloud_sync_fast|full|slow / cloud_billing / metering.
