//! # `op-connect` — Platform / marketplace tier for OpenPay
//!
//! `op-connect` is the Stripe-Connect / Adyen-MarketPay / Square-Capital
//! equivalent inside OpenPay. A platform that wants to onboard
//! sub-merchants, KYB them, split payments across multiple
//! beneficiaries, run a payout schedule, hold rolling reserves, and
//! file 1099-Ks plugs this crate in between [`op-core`](../op_core)
//! (payment primitives) and the rail-driver crates (`op-batch`,
//! `op-rails-a2a`, `op-rails-card`).
//!
//! ## What this crate ships
//!
//! - [`account`] — connected-account model (Standard / Express / Custom),
//!   capability set, requirements vector.
//! - [`kyb`] — Know-Your-Business profile, beneficial-owner model,
//!   FinCEN CDD (31 CFR § 1010.230) and EU AMLD5 (Directive (EU)
//!   2018/843, Art. 3(6)) compliance helpers.
//! - [`onboarding`] — stepwise onboarding state machine and the
//!   [`OnboardingProvider`](onboarding::OnboardingProvider) trait that
//!   isolates side-effects from policy. Ships a native in-process
//!   provider and documents the adapter shape for Stripe Connect /
//!   Adyen MarketPay migration.
//! - [`screening`] — wires the [`op-screening`] sanctions index, plus
//!   adds PEP and adverse-media coordination per FATF Recommendation 12.
//! - [`split`] — split-payments engine with sum / negativity /
//!   currency / duplicate-destination validation.
//! - [`transfer`] — internal-ledger transfer between connected accounts.
//! - [`payout`] — schedule arithmetic, rolling-reserve withholding,
//!   payout-instruction builder.
//! - [`liability`] — Platform / SubMerchant / Hybrid liability models
//!   driving tax attribution, dispute pass-through, and PCI scope
//!   inheritance.
//! - [`tax_reporting`] — IRS Form 1099-K and Form 1042-S generators,
//!   driven by the IRS 2024-instructions threshold table (IRS Notice
//!   2024-85 phased step-down from $20k/200tx to $600 by 2026).
//! - [`tos`] — terms-of-service acceptance ledger with idempotent
//!   replay semantics.
//!
//! ## What this crate does NOT do
//!
//! - **Rail submission.** Payout instructions hand off to `op-batch`
//!   (ACH / SEPA / BACS / wire) or `op-rails-a2a` (FedNow / RTP); we
//!   compute the instruction and stop.
//! - **Sanctions list ingestion.** That's `op-screening`'s job; we
//!   compose its `Screener` with PEP and adverse-media variants.
//! - **Document verification.** Identity-document review is delegated
//!   to a third-party provider (Persona, Onfido, Stripe Identity); we
//!   carry vault references and a verification state.
//! - **State-by-state tax-license tracking.** Out of scope; integrate
//!   a service like Avalara or TaxJar at the application layer.
