# @lssm-tech/integration.provider-einvoicing

French Factur-X generation and PDP submission for ContractSpec BillingOS.

- `./cii` — pure EN16931 Cross-Industry Invoice (CII) XML builder.
- `./facturx` — `FacturXGeneratorPort` + a Mustangproject-backed PDF/A-3 hybrid generator.
- `./conformance` — EN16931 / Factur-X CIUS-FR validation via Mustangproject (JVM).
- `./pdp` — `PdpSubmissionPort`, a deterministic mock, a fail-closed production stub, and an idempotent submission guard.

## Conformance toolchain

Validator: **Mustangproject CLI 2.17.0** (vendored at `vendor/Mustang-CLI-2.17.0.jar`,
from Maven Central `org.mustangproject:Mustang-CLI:2.17.0`). It runs XSD schema
validation and EN16931 / Factur-X Schematron business rules over the JVM
(OpenJDK 17). Set `EINVOICING_JAVA_BIN` to override the `java` binary.

Conformance and embedding are never faked: if the jar or JVM is absent, the
generator returns the machine CII XML with `embedded:false`, and the validator
returns `available:false` with a skip reason.

Depends on `@lssm-tech/lib.billing-france` (TVA rounding, flow classification)
and `@lssm-tech/lib.billing-spec` (invoice types). This package owns Factur-X
generation + PDP submission; the lib stays pure.
