Abstract Class: CreditStore

Defined in: javascript/src/credits/store.ts:111

Abstract base for credit storage backends.

Split into two tiers:

• Core (abstract, must be implemented): balance/credit ops, the atomic lease lifecycle, bursar-config versioning, plan management, refunds, and expiry sweeping. Every backend needs these.
• Optional capabilities (concrete, default-throwing): usage analytics, ledger listing, and shared team-balance pools. A custom store that doesn't need these can skip them entirely — the default implementation throws CapabilityNotSupportedError instead of forcing a stub.

createLease()

abstract createLease(userId, amount, operationType, options): Promise<LeaseResult>

Defined in: javascript/src/credits/store.ts:152

Atomically acquire a lease (hold) — the only authoritative admission control.

Under one critical section the store: (1) ensures the balance row exists; (2) enforces maxConcurrent by counting active leases for (userId, operationType); (3) enforces plan entitlements and quotas; (4) computes available = balance − Σ active holds and rejects with error="insufficient_credits" if available − amount < floor; (5) inserts an active lease expiring after ttlSeconds. Business failures are returned via LeaseResult.error; the store never raises domain exceptions.

settleLease()

abstract settleLease(userId, leaseId, amount, options?): Promise<DeductionResult>

Defined in: javascript/src/credits/store.ts:168
