Proof step 30 from proof size-0 (previous step)

# groupblock(gndx, lax, m1).gndlist = # groupblock(gndx, lax, m1).ladrlist, (range ri | m).size = 0, ri[key] = @(m, m0, 0), gstore[m] = groupblock(gndx, lax, m1), inv(gstore \ ginval), inv-flashsize(groupblock(gndx, lax, m1).gndlist, groupblock(gndx, lax, m1).ladrlist), key-cons(key, nodes(gstore ↓, ginval)[@(m, m0, 0)]), m ∈ gstore, @(m0, 0) ∈ prefixn(valid-group-nodes(gndx), lax), key ∈ ri ⊦ dups(groupblock(gndx, lax, m1).ladrlist), m ∈ ginval

And obtained the following new goals

Proof step 31:
# gndx = # lax, (range ri | m).size = 0, gstore[m] = groupblock(gndx, lax, m1), ri[key] = @(m, m0, 0), inv(gstore \ ginval), inv-flashsize(gndx, lax), key-cons(key, nodes(gstore ↓, ginval)[@(m, m0, 0)]), key ∈ ri, @(m0, 0) ∈ prefixn(valid-group-nodes(gndx), lax), m ∈ gstore ⊦ dups(lax), m ∈ ginval

Rule argument

Additional information

Used simplifier rules: ⊦ groupblock(gndx, lax, m).ladrlist = lax; (s)% ⊦ groupblock(gndx, lax, m).gndlist = gndx; (s)
