Proof step 4 from proof pubBar-init (previous step)

by ' + bytes0 ≠ [], ∀ class, r, i, st. initdone(class, putByteArray(bytes0, r, i, st)) ↔ initdone(class, st) ⊦ initdone(class, putByteArray((by ' + bytes0) .rest, r, i + 1, st)[r -- i ', byteval((by ' + bytes0) .first)]) ↔ initdone(class, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
∀ class, r, i, st. initdone(class, putByteArray(bytes0, r, i, st)) ↔ initdone(class, st) ⊦ initdone(class, putByteArray(bytes0, r, i + 1, st)) ↔ initdone(class, st)
