Proof step 92 from proof write-known (previous step)

rs1 ∩ rs0 = ∅, ((r => o1))(mk(rs1, f(r; o1))), R[rs0, f(r; o1), g], r ∈ rs0, ∀ r. r ∈ rs1 → g(r) = a ⊦ # rs0 = 0, rs0 = ∅, (a[r => f(r)] * R)[rs1 ∪ rs0, f, g], a[r => f(r)][rs1, f, g] ∧ R[rs0, f, g]

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 93:
⊦ ((r => o))(H) ↔ H = (∅ ++ r)[r, o] ∧ r ≠ null
Proof step 94:
mk(rs1, f(r; o1)) = (∅ ++ r)[r, o1], rs1 ∩ rs0 = ∅, R[rs0, f(r; o1), g], r ∈ rs0, ∀ r. r ∈ rs1 → g(r) = a ⊦ # rs0 = 0, r = null, rs0 = ∅, (a[r => f(r)] * R)[rs1 ∪ rs0, f, g], a[r => f(r)][rs1, f, g] ∧ R[rs0, f, g]

Rule argument

spec: maplet name: maplet seq: ⊦ ((r => o))(H) ↔ H = (∅ ++ r)[r, o] ∧ r ≠ null subst: [H, o, r] → [mk(rs1, f(r; o1)), o1, r] flags: <all paths>
