/**
 * OpenAPI route table for the documents library (`/api/documents/inbound/*`).
 *
 * Part of the OpenAPI route table; aggregated in `./index.ts`. The confirm +
 * edit + list request bodies reuse the runtime schemas from
 * `@/lib/validations/inbound-documents` so the wire contract stays
 * single-source.
 *
 * The v1.25.x library inverts the original OCR-inbox: upload is STORE-ONLY and
 * provider-free (a file is always filable, encrypted at rest); AI extraction is
 * a separate, opt-in action on an already-stored document. Extraction
 * reproduces what the document states (stated codes/status only) into a staging
 * area — it never interprets or diagnoses. Nothing reaches the structured
 * stores until the confirm route commits the user's approvals; a low-confidence
 * fact fails closed.
