Establish behavioral equivalence of evaluated implementation lineages

Establish whether the Fractal overlay, Bridge carry overlay, and MIKASA implementation lineages used in the evaluated experiments are behaviorally equivalent under the released configuration.

Background

The paper evaluates multiple implementation lineages across SimplerEnv, Bridge, and MIKASA experiments. Because some source snapshots or runtime bindings are incomplete, the results cannot safely be transferred between lineages until their behavioral equivalence is established.

References

Whether these lineages are behaviorally equivalent under the released configuration is not established, and no result is transferred across them.
