Proof step 10 from proof compatfields-mode (previous step)

sk .fs = mkfs(class0, ty, fieldvar), sk ∈ instfields(class), sk ∈ instfields(class) → r -- sk ∈ st ∧ is_fskey(sk) ∧ compat(str, st[r -- sk], sk .fs .type, st[_mode, val]) ⊦ r = jvmref, r -- sk ∈ st ∧ ¬ is_indexkey(sk) ∧ compat(str, st[r -- sk], ty, st)

And obtained the following new goals

Proof step 9:
sk .fs = mkfs(class0, ty, fieldvar), is_fskey(sk), r -- sk ∈ st, sk ∈ instfields(class), r ∈ st, compat(str, st[r -- sk], ty, st[_mode, val]) ⊦ r = jvmref, compat(str, st[r -- sk], ty, st)
