The generator loaded both codec classes from the published release JAR, then called their CODECs with NbtOps.INSTANCE.

Golden fixtures were generated in the isolated NeoForge GameTest server by
runs/v3-offline-20260909/pm-autoplayer/harness-nf1211/src/main/java/com/kuronami/pmtest/GoldenFixtureExportGameTests.java.
NeoForge ModList resolved music_disc_maker to the same published release JAR above.
The test created each state through the old JAR's public methods and called the old block entity's saveWithFullMetadata.
The stopped fixture is the old block entity's natural empty stopped state; it does not claim a stopped disc state that v2 cannot create through its public controls.
