Proof step 17 from proof mod-other-hp2 (previous step)

rs2 ∩ rs = ∅, rs1 ∩ rs2 = ∅, rs1 ∩ rs = ∅, P(mk(rs1, f)), a0[P0][rs2, f, g], R[rs, f, g], ∀ r. r ∈ rs1 → g(r) = a ⊦ g(r) = a0, g(r) = a, a[P][rs1, f(r; o), g], (a[P] * a0[P0] * true)[rs1 ∪ rs2 ∪ rs, f(r; o), g]

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 18:
⊦ R[rs, f, g] ↔ R(mk(rs, f, g))
Proof step 19:
rs1 ∩ rs = ∅, rs1 ∩ rs2 = ∅, rs2 ∩ rs = ∅, P(mk(rs1, f)), R[rs, f, g], a0[P0][rs2, f, g], ∀ r. r ∈ rs1 → g(r) = a ⊦ g(r) = a, g(r) = a0, (a[P] * a0[P0] * true)[rs1 ∪ rs2 ∪ rs, f(r; o), g], a[P](mk(rs1, f(r; o), g))

Rule argument

spec: heap-fun, inst: heap-aux name: apply seq: ⊦ R[rs, f, g] ↔ R(mk(rs, f, g)) subst: [g, f, rs, R] → [g, f(r; o), rs1, a[P]] flags: <all paths>
