net_balanceendpoint, removecredit_grants/invoicesstreams, add async webhook support, addskipLimitforrate_cardsapps/cache-sidecar): standalone HTTP process for optimistic balance enforcement — reads sync engine checkpoints from Redis, tracks pending usage events, returns merged balance in <50msArchitecture
Two Redis namespaces with strict ownership:
sync:*— checkpoint data written by sync engine (read-only to sidecar)optimistic:*— pending events + derived balance (sidecar-owned)Three HTTP endpoints:
GET /v1/health,GET /v1/balance/:cid,POST /v1/eventsTest plan
