Proof step 5 from proof crash-neutral-sync-device (previous step)

ebm-cons(avols0), ebm-cons(avols), avols ⊆ avols0 ⊦ ∃ err0. (⌊err0⌋ ∨ err0 = ESUCCESS) ∧ ⟨err := err0⟩ true

User applied rule exists right

And obtained the following new goals

Proof step 6:
ebm-cons(avols), ebm-cons(avols0), avols ⊆ avols0 ⊦ (⌊ESUCCESS⌋ ∨ ESUCCESS = ESUCCESS) ∧ ⟨err := ESUCCESS⟩ true

Rule argument

pos: right 1 terms: ESUCCESS abort: F discard: T computed: T
