Proof step 4 from proof crash-neutral-sync-device (
previous step
)
ebm-vol-inv(avol), avol ⊆ avol0 ⊦ ⟨choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0⟩ true
Heuristic symbolic execution applied rule choose right
And obtained the following new goals
Proof step 5
:
ebm-vol-inv(avol), avol ⊆ avol0 ⊦ ∃ err0. (⌊err0⌋ ∨ err0 = ESUCCESS) ∧ ⟨err := err0⟩ true
Rule argument
