Constant DECLARED_PARAM_SERVICE_SHAPES 

pub const DECLARED_PARAM_SERVICE_SHAPES: Option<&[[usize; 9]]>;

phase-446 F3 – per node, the contract’s declared parameters as the parameter services see them: [params, name_bytes, prefixes, prefix_bytes, strings, byte_arrays, bool_arrays, word_arrays, string_arrays] (NROS_DECLARED_PARAM_SERVICE_SHAPE). None when the contract does not declare every node’s parameters.
