v3 Bytecode Format (BC2) Checkpoint

Predict fresh artifacts, diagnose a broken invariant, and test a version boundary. Select one answer per multiple-choice question; numeric responses use the stated integer format. Use review links to revisit the relevant representation, then attempt the independent transfer task.
