Proof step 43 from proof putbar-classfield-onlymod (previous step)

st[r -- sk] = refval(r0), okbytearray(r0, st), sk ∈ instfields(st[r -- _type] .type .class), is_classtype(st[r -- _type] .type) ⊦ r = jvmref, junkref(str, r, st), onlyModified(str, r, st, putByteArray(bytes, r0, st))

User applied rule cut formula

And obtained the following new goals

Proof step 42:
st[r -- sk] = refval(r0), okbytearray(r0, st), sk ∈ instfields(st[r -- _type] .type .class), is_classtype(st[r -- _type] .type) ⊦ r = r0, r = jvmref, junkref(str, r, st), onlyModified(str, r, st, putByteArray(bytes, r0, st))

Rule argument

[fma-arg: r = r0]
