Proof step 15 from proof range-put (previous step)

zbrar[m].key < key, m + 1 < # zbrar ⊦ zbrar[m + 1].key < key, (key0 = key ∨ key0 ∈ ri ∧ zbrar[m].key < key0 → key0 ∈ (ri |> zbrar[m].key)[key, adr]) ∧ (key0 ∈ (ri |> zbrar[m].key)[key, adr] → ri[key, adr][key0] = (ri |> zbrar[m].key)[key, adr][key0])

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: store, inst: node-index name: At-other seq: ⊦ key ≠ key0 → ri[key0, adr][key] = ri[key] subst: [key, adr, key0, ri] → [key0, adr, key, ri |> zbrar[m].key] flags: <all paths>

Additional information

Used simplifier rules: ⊦ key ≠ key0 → (key ∈ ri[key0, adr] ↔ key ∈ ri); (s)% ⊦ key0 ∈ ri |> key1 ↔ key0 ∈ ri ∧ key1 < key0; (s)% ⊦ key ≠ key0 → ri[key0, adr][key] = ri[key]; (s)% ⊦ key1 < key0 ∧ key0 ∈ ri → (ri |> key1)[key0] = ri[key0]; (s)% ⊦ key ∈ ri[key, adr]; (s)% ⊦ ri[key, adr][key] = adr; (s) Used terms: key0, adr, key, ri |> zbrar[m].key
