User applied rule call right

And obtained the following new goals

Proof step 12:
key = inodekey(ino), fo.inodes?, ro.inodes?, file-node-cons(fs, ri), log-cons(log, fs), orphans-cons(fs, ri, ro), replay-cons-strong(fs, ri, ro, fi, fo, log), ri-inj(fi), ri-inj(ri), ubifs-cons(fs, ri, ro, fi, fo, log), inodekey(ino) ∈ ri ⊦ ⟪if ri-cons(ri, fs) then {fail_or_success#(; ; err); if err = ESUCCESS then {boolvar := key ∈ ri; if boolvar then nd := fs[ri[key]] else nd := ?} else boolvar := ?, nd := ?} else abort; if err = ESUCCESS ∧ boolvar then inode := mkinode(ino, nd.meta, nd.directory, nd.nlink, (nd.directory ⊃ nd.nsubdirs;0), nd.size)⟫ true
