reader_version

Inside a node type's READ callback: the host document-format version the payload was written with, so a plugin can migrate an older payload (it still reads its own bytes; this just tells it which layout to expect). Valid only during read; returns 0 otherwise.

Declared in sdk/include/yu3d_plugin.h. Reached through the host table: host->reader_version(…). Guard with YU3D_HOST_HAS(host, reader_version) if your plugin must also load in an older host.
