Proof step 3 from proof inv-is-log-empty (previous step)

keyset(gch) = gc-heap(lpt, log), bufs-log-only(bleb, log, lpt), log-group-block(log, lpt), lpt-ram-flash(lpt, lpt0, log), ¬ dups(log) ⊦ ⟪persistence_is_log_empty#(log; ; empty?)⟫ true

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 4:
keyset(gch) = gc-heap(lpt, log), bufs-log-only(bleb, log, lpt), log-group-block(log, lpt), lpt-ram-flash(lpt, lpt0, log) ⊦ ⟪empty? := log = []⟫ true, dups(log)

Rule argument

pos: right 1
