Proof step 38 from proof fids-in (previous step)

sdt[str][p0] = fnode(fid), str ∈ sdt, p0 ∈ sdt[str], ∀ tree, fid. tree[p0] = fnode(fid) ∧ p0 ∈ tree → fid ∈ tree.fids ⊦ fid ∈ sdt.fids

User applied rule all left

And obtained the following new goals

Proof step 39:
sdt[str][p0] = fnode(fid), p0 ∈ sdt[str], str ∈ sdt, sdt[str][p0] = fnode(fid) ∧ p0 ∈ sdt[str] → fid ∈ sdt[str].fids ⊦ fid ∈ sdt.fids

Rule argument

pos: left 4 terms: sdt[str], fid abort: F discard: T computed: T
