+### Fixed

+- **`mix credo --strict` `FunctionArity` finding** —
+  `Longbridge.QuoteContext.paginate/9` took 9 parameters, exceeding
+  the max-8 limit and causing the strict Credo run to exit with rc=8.
+  The two loop-state arguments (`acc`, `seen`) have been collapsed
+  into a single `state` map, dropping the arity to 8. Public API is
+  unchanged.
