Billing Model
Credits Wallet
Topup/charge/refund/adjust all recorded as immutable wallet transactions.
Pricing
Capability-level pricing rules with transparent settlement behavior.
Concurrency Safety
Hold + Capture
Async runs reserve credits first, then capture on success or release on failure/cancel.
Governance Coupling
Auditable Blocks
Model disabled / policy blocked / insufficient credits all generate audit records.
Current Global Rules
No global pricing rules configured
Admin can configure rules in Admin > Pricing Rules.
