Proof step 15 from proof inv-commit (previous step)

# lpt = # avol, # lpt0 = # avol, awbuf-inv(avol, bleb), synced(avol), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪isbuf := true; ns0 := ?⟫ (# lpt = # avol), err0 = ESUCCESS

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
