Proof step 1 from proof prepost-read-orphans (conclusion)

persistence-io-inv(sb, logoff, avol, lpt, log, orphans0), ebm-vol-inv(avol) ⊦ ⟪persistence_io_read_orphans#(sb, avol; orphans; err)⟫ ((err = ESUCCESS ∨ ⌊err⌋ ) ∧ (err = ESUCCESS → orphans = orphans0))

System applied rule normalize

And obtained the following new goals
