-/// QuickLendX Smart Contract Library
-///
-/// This crate contains the core arithmetic modules for the QuickLendX
-/// invoice-financing protocol built on Stellar's Soroban platform.
-///
-/// ## Modules
-///
-/// - [`settlement`]    — Invoice settlement payout computation
-/// - [`fees`]          — Protocol fee calculations (origination, servicing, default, early-repayment)
-/// - [`profits`]       — Investor return metrics and platform revenue aggregation
-/// - [`verification`]  — Centralized guards preventing unverified actors from restricted actions
-///
-/// ## Safety Philosophy
-///
-/// All financial arithmetic uses `u128` with `checked_*` operations.
-/// Any computation that would overflow returns `None`; callers must handle
-/// this as an error condition. This eliminates silent wrapping overflow,
-/// underflow, and sign-extension bugs.
-///
-/// The verification module enforces a **deny-by-default** policy: every
-/// restricted action requires the caller to prove verified status through
-/// a guard function.  Pending, rejected, and unknown actors are blocked.
