Heuristic unfold applied rule call right

And obtained the following new goals

Proof step 12:
key = inodekey(m), ro = orphans(fs, ri), strings = strings0, fs[ri[inodekey(m)]].directory, 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-inj(ri), ri-inj(fi), ubifs-cons(fs, ri, orphans(fs, ri), fi, fo, log), inodekey(m) ∈ ri, asynced → boolvar ⊦ ⟪choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then strings := dentries(key, ri) else strings := ?⟫ ⟨afs_readdir#(mkinode(m, md, boolvar0, m0, m1, m2), abs-dirs(fs, ri), abs-files(fs, ri), asynced; strings0, err0)⟩ ((asynced → boolvar) ∧ strings = strings0 ∧ err = err0)

Rule argument

pos: right 1

Additional information

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