Proof step 39 from proof write-known (previous step)

rs1 ∩ rs0 = ∅, R[rs0, f, g], a[r => o0](mk(rs1, f, g)) ⊦ f(r) = o0, a[r => o1][rs1, f(r; o1), g]

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 40:
⊦ a[P](mk(rs, f, g)) ↔ P(mk(rs, f)) ∧ (∀ r. r ∈ rs → g(r) = a)
Proof step 41:
rs1 ∩ rs0 = ∅, ((r => o0))(mk(rs1, f)), R[rs0, f, g], ∀ r. r ∈ rs1 → g(r) = a ⊦ f(r) = o0, a[r => o1][rs1, f(r; o1), g]

Rule argument

spec: <toplevel> name: lift-aux seq: ⊦ a[P](mk(rs, f, g)) ↔ P(mk(rs, f)) ∧ (∀ r. r ∈ rs → g(r) = a) subst: [g, f, rs, P, a] → [g, f, rs1, r => o0, a] flags: <all paths>
