Proof step 6 from proof readpage-get (previous step)

files[m] = mkfile(m3, md0, m4, content), inode = mkinode(m, md, boolvar, m0, m1, m2), pageno = n ⊦ [if pre-readpage(inode, pageno, buf, dirs, files) then { {if pageno ∈ files[inode.ino].content then buf := files[inode.ino].content[pageno] else buf := zeropage; err := ESUCCESS} or fail#(; ; err)} else abort] (err = ESUCCESS ∧ buf = getpage(n, content) ∨ ⌊err⌋ )

Heuristic conditional right split applied rule if right

And obtained the following new goals

Proof step 7:

Proof step 23:
files[m] = mkfile(m3, md0, m4, content), inode = mkinode(m, md, boolvar, m0, m1, m2), pageno = n ⊦ [abort] (err = ESUCCESS ∧ buf = getpage(n, content) ∨ ⌊err⌋ ), pre-readpage(inode, pageno, buf, dirs, files)
