* Remove the dead InputAccessor traits and the uncallable test helper built on them * Replace raw node input indices with macro-generated parameter symbols across the editor * Audit dynamic input index usage, converting to parameter symbols and named input position constants * Abstract the remaining input index plumbing behind ParameterRef APIs and accessors * Build SetInputValue messages as struct literals to keep message enums impl-free * Delete the typed parameter markers in favor of explicit-output test introspection * Wire the interpolation control path input per chain node type * Return no input when a parameter symbol is read against the wrong node's parameter view
