+// Resolve returns the first error found in the error chain which matches an
+// error defined in this package or context error. A raw, unwrapped error is
+// returned or ErrUnknown if no matching error is found.
+//
+// This is useful for determining a response code based on the outermost wrapped
+// error rather than the original cause. For example, a not found error deep
+// in the code may be wrapped as an invalid argument. When determining status
+// code from Is* functions, the depth or ordering of the error is not
+// considered.
+//
+// The search order is depth first, a wrapped error returned from any part of
+// the chain from `Unwrap() error` will be returned before any joined errors
+// as returned by `Unwrap() []error`.
