Proof step 10 from proof validref-put-byteval (previous step)

sk .fs .type = byte_type, is_bytevalue(st[r -- sk]), is_fskey(sk), st[r0 -- _type] .type ≤ ty ⊦ sk = _type, sk = _length, r = jvmref, r0 = jvmref, r0 = jvmref ∨ (st[r -- sk, byteval(by)][r0 -- _type]) .type ≤ ty ∧ ¬ junkref(str, r0, st[r -- sk, byteval(by)]), junkref(str, r0, st)

Proof step 9:
sk .fs .type = byte_type, is_bytevalue(st[r -- sk]), is_fskey(sk), st[r0 -- _type] .type ≤ ty, junkref(str, r0, st[r -- sk, byteval(by)]) ⊦ sk = _type, sk = _length, r = jvmref, r0 = jvmref, junkref(str, r0, st)
