// The boundary mapper (src/lib/wire.ts) and the pagination iterators
// (src/lib/paginate.ts) are the hand-written runtime modules with no
// compile-time guard, so their behavior is covered entirely by tests. Hold
// them at full statement/line/function coverage. The branch threshold is
// below 100 because wire.ts's residual uncovered branches are defensive
// nullish-coalescing arms (`?? []`, `?? {}`) guarding zod internals that the
// preceding type-guard already makes non-null — unreachable with any real
// schema, so not worth contriving inputs for. paginate.ts itself has no such
// residual: tests/paginate.spec.ts exercises every stop condition (empty
// page, short page, exact-total page, absent next cursor) and both
// PaginationLimitExceededError throws.
