Proof step 29 from proof refine-check-commit (previous step)

fo.inodes?, orphans(fs, ri).inodes?, afs-cons(abs-dirs(fs, ri), abs-files(fs, ri)), file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, orphans(fs, ri)), replay-cons-strong(fs, ri, orphans(fs, ri), fi, fo, log), ri-cons(ri, fs), ri-inj(fi), ri-inj(ri), ubifs-cons(fs, ri, orphans(fs, ri), fi, fo, log), asynced → boolvar ⊦ ⟪fail#(; ; err); boolvar := ?⟫ ⟨afs_check_commit#(abs-dirs(fs, ri), abs-files(fs, ri); err0; asynced)⟩ ((asynced → boolvar) ∧ err = err0)

Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 30:
orphans(fs, ri).inodes?, fo.inodes?, afs-cons(abs-dirs(fs, ri), abs-files(fs, ri)), file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, orphans(fs, ri)), replay-cons-strong(fs, ri, orphans(fs, ri), fi, fo, log), ri-cons(ri, fs), ri-inj(ri), ri-inj(fi), ubifs-cons(fs, ri, orphans(fs, ri), fi, fo, log), asynced → boolvar ⊦ ⟪choose err0 with ⌊err0⌋ in err := err0; boolvar := ?⟫ ⟨afs_check_commit#(abs-dirs(fs, ri), abs-files(fs, ri); err0; asynced)⟩ ((asynced → boolvar) ∧ err = err0)

Rule argument

pos: right 1

Additional information

Used simplifier rules: fail#(; ; ERR){choose ERR0 with ⌊ERR0⌋ in ERR := ERR0};
