Proof step 10 from proof junkref-putbar-01 (previous step)

okarray(r0, byte_type, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)[r0 -- i ', byteval(by)]), r0 ∈ st ⊦ r0 = jvmref, junkref(str, r, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)), okval(byteval(by), st[r0 -- _type] .type .type)

And obtained the following new goals

Proof step 4:
⊦ okarray(r, ty, st) ↔ okreftype(refval(r), mkarraytype(ty), st) ∧ r ≠ jvmref ∧ r -- _length ∈ st ∧ is_integervalue(st[r -- _length]) ∧ 0 ≤ st[r -- _length] .intval ∧ is_arrayref(r, st[r -- _length] .intval, st) ∧ (∀ j. 0 ≤ j ∧ j < st[r -- _length] .intval → oktype(st[r -- j '], ty, st))
Proof step 9:
okreftype(refval(r0), mkarraytype(byte_type), st) ∧ r0 ≠ jvmref ∧ r0 -- _length ∈ st ∧ is_integervalue(st[r0 -- _length]) ∧ 0 ≤ st[r0 -- _length] .intval ∧ is_arrayref(r0, st[r0 -- _length] .intval, st) ∧ (∀ j. 0 ≤ j ∧ j < st[r0 -- _length] .intval → oktype(st[r0 -- j '], byte_type, st)), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)[r0 -- i ', byteval(by)]), r0 ∈ st ⊦ r0 = jvmref, junkref(str, r, st), junkref(str, r, putByteArray(bytes0, r0, i + 1, st)), okval(byteval(by), st[r0 -- _type] .type .type)
