Proof step 3 from proof refine-readdir (previous step)

err = err0, strings = strings0, fs[ri[inodekey(inode.ino)]].directory, 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-inj(fi), ri-inj(ri), ubifs-cons(fs, ri, orphans(fs, ri), fi, fo, log), inodekey(inode.ino) ∈ ri, asynced → boolvar ⊦ ⟪aubifs_readdir#(inode, ri, fi, orphans(fs, ri), fo, fs, log, boolvar; strings, err)⟫ ⟨afs_readdir#(inode, abs-dirs(fs, ri), abs-files(fs, ri), asynced; strings0, err0)⟩ ((asynced → boolvar) ∧ strings = strings0 ∧ err = err0)

Heuristic weak unfold applied rule call right

And obtained the following new goals

Proof step 4:
err = err0, ro = orphans(fs, ri), strings = strings0, fs[ri[inodekey(inode.ino)]].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(inode.ino) ∈ ri, asynced → boolvar ⊦ ⟪if pre-readdir(inode.ino, fs, ri) then choose key with true in {key := inodekey(inode.ino); aubifs_core_index_entries#(key, ri, fi, ro, fo, fs, log, boolvar; strings; err)} else abort⟫ ⟨afs_readdir#(inode, abs-dirs(fs, ri), abs-files(fs, ri), asynced; strings0, err0)⟩ ((asynced → boolvar) ∧ strings = strings0 ∧ err = err0)

Additional information

Used simplifier rules: aubifs_readdir#(INODE, RI, FI, RO, FO, FS, LOG, CSYNCED; NAMES, ERR) {if pre-readdir(INODE.ino, FS, RI) then choose KEY with true in {KEY := inodekey(INODE.ino); aubifs_core_index_entries# (KEY, RI, FI, RO, FO, FS, LOG, CSYNCED; NAMES; ERR)} else abort };
