The draft soundness fix (tlaplus/tlapm#314) exposes a completeness gap: coalescing assigns different opaque identifiers to the lemma's n,o and the goal's u,v. Expand ENABLED and the relevant definitions so ordinary first-order instantiation can discharge the step. The proof statement and assumptions remain unchanged. Unfolding definitions and expanding ENABLED preserve the TLA+ meaning of the obligation.
