# `@lssm-tech/lib.billing-runtime`

Pure, backend-neutral BillingOS runtime helpers over `@lssm-tech/lib.billing-spec`.

France readiness metadata is not PA accreditation, production PA submission, legal advice, or tax advice.

## Runtime helpers

`@lssm-tech/lib.billing-runtime` provides pure helper engines over `@lssm-tech/lib.billing-spec`:

- quote/order/invoice/payment/reconciliation lifecycle projections;
- deterministic pricing totals with an injected synchronous tax-calculation port;
- local workflow event creation/appending;
- payment-state reconciliation hints;
- draft accounting export shaping;
- deterministic quote-to-cash cockpit projections with lifecycle, approval-packet, surface, and finance-review handoff metadata; and
- agent planning guards that produce approval packets instead of executing high-impact billing actions.

The package performs no network calls, filesystem access, provider SDK calls, credential handling, persistence writes, PA submission, or autonomous production billing execution.

## BillingOS truth and FinanceOS handoff

The additive `./truth` surface projects normalized billing facts into the
append-only economic-evidence lifecycle, provides a tenant-isolated in-memory
reference store with revision and idempotency guards, records superseding
corrections without deleting history, and validates balanced, company-scoped
posting handoffs. A posting handoff remains a proposal until an explicit
ContractSpec Connect authorization reference is supplied.

## Persistence ports (additive)

Backend-neutral port interfaces that a host implements against its store; the package defines the contracts, never the adapters:

- `InvoiceRepositoryPort` — persist and read issued invoices.
- `EventLogAppendPort` — append-only billing workflow event log.
- `InvoiceChainAppendPort` — append entries to the per-period invoice hash-chain.
- `CreditNoteRepositoryPort` — persist and read credit notes (avoir).

## Observability (additive)

- `BillingObservabilityPort` — structured, correlation-id-propagating observability hook for issuance and submission.
- Field-level redaction of SIREN/SIRET/VAT identifiers, secrets, and amounts so no sensitive payload is logged; redaction is applied before any sink receives the record.

## Service agreements (`./service-agreement`, additive)

Pure engines and host ports for `@lssm-tech/lib.billing-spec/service-agreement`:

- `recordServiceUsage` / `correctServiceUsage` over `ServiceUsageLedgerPort`:
  atomic usage + outbox + work-completion transaction; identical replay returns
  the stored receipt, a changed payload conflicts, corrections supersede the
  current head without deleting history.
- `recordMeteredServiceUsage` over `ServicePriceTablePort` and
  `MeteredServiceUsageStorePort`: meters one platform service call exactly
  once per tenant and usage ref, rated by `selectServicePriceVersion` /
  `rateServiceUsage` against the version effective at the occurrence. It never
  guesses a price: the call is `unpriced` until the owner sets one. An
  optional `MeteredServiceBillingPort` appends the call to the service usage
  ledger through `recordServiceUsage` when the tenant's agreement sells the
  meter; a replay returns the stored receipt and a changed payload conflicts.
  `occurredAt` is metadata: the first recorded occurrence wins, and a retry
  after a crash that left the call in the ledger only adopts that ledger event.
  The bound ledger must scope event ids (`usage:<usageRef>`) by tenant.
  `toMeterServiceUsageOutput` projects a result onto the
  `billing.service.usage.meter` output; the host emits its
  `billing.service.usage.metered` audit record.
  `InMemoryServicePriceTable` and `InMemoryMeteredServiceUsageStore` are the
  reference adapters.
- `computeServiceInvoiceDraft`: deterministic, digest-bound drafts per cadence
  period with frozen price editions; late usage and post-issue corrections
  become adjustment or credit lines for the earlier period instead of
  rewriting issued invoices; BYOK never yields passthrough.
- `reserveServiceCapacity` / `settleServiceReservation` / `resumeServiceBudget`
  over a compare-and-set `ServiceBudgetStorePort`: allowance, approved overage
  ceiling, bounded grace and pause, plus a separate internal provider budget.
- `buildOnPremUsageBatch` / `importOnPremUsageBatch`: signed digest-only batches
  with replay, gap, fork, instance-change, key-rotation and clock checks.
- `submitServiceInvoiceOnce` / `issueServiceInvoice` / `applyServicePaymentEvent`:
  approved, exactly-once submission (unique per tenant and merchant), approved
  issue, and idempotent, order-safe payment evidence.
- `openServiceCollection` / `issueStoredServiceInvoice` /
  `receiveServicePaymentEvent` over `ServiceCollectionStorePort`: collection
  state per invoice under a row lock; a verified webhook is stored once per
  merchant and provider event id (redelivery is a duplicate, a changed payload
  conflicts), and events that arrive before issuance are held and applied at
  issuance.
- `requireServiceApproval`: consequential actions verify an
  `OperationApprovalReceipt` through the host's `OperationApprovalPort`
  (subject, operation key/version, input digest, consumed nonce). A
  caller-supplied decision string is never authority; with no port bound the
  action fails closed.

In-memory reference adapters mirror the required host semantics for tests; they
are not durable storage. Hosts bind the ports to their database.
