# Focus NFCom adapter (Master Prompt §6.11, ADR-0011)

Implement: adapter, unique/idempotent reference per document, emission, query, cancellation, webhooks, persistence of the normalized request without secrets, response/status, keys/identifiers, XML/PDF artifacts when available, retries with backoff, dead-letter/manual retry.

Classification comes from `product_fiscal_profiles` (`document_type = 'NFCOM'`, `nfcom_cclass_id`, etc.) — never inferred ad hoc at emission time.
