Before changing a deprecated opcode, check the maintenance policy
and replacement catalog. These record which names
are aliases and which historical behavior remains for compatibility. Source files
carry CSOUND_DEPRECATED_OPCODE descriptors beside registrations and
CSOUND_PRESERVE_LEGACY_BEHAVIOR markers above frozen functions. Read them before
changing historical output.
