Proof step 16 from proof abs-nodes-inv-flashsize-h (previous step)

# gndx0 = # lax0, m0 = m, m1 = # buf1, abs-node(buf1, gnd), abs-nodes(buf0, m + # buf1, gndx0, lax0, weak), ∀ buf2, m, gndx, lax, weak. # buf2 < #(buf1 + buf0) → abs-nodes(buf2, m, gndx, lax, weak) → inv-flashsize(gndx, lax) ⊦ 2 * NODE_HEADER_SIZE + gnd.alignedsize = m1 ∧ inv-flashsize(gndx0, lax0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
# gndx0 = # lax0, abs-node(buf1, gnd), abs-nodes(buf0, m + # buf1, gndx0, lax0, weak), ∀ buf2, m, gndx, lax, weak. # buf2 < #(buf1 + buf0) → abs-nodes(buf2, m, gndx, lax, weak) → inv-flashsize(gndx, lax) ⊦ 2 * NODE_HEADER_SIZE + gnd.alignedsize = # buf1 ∧ inv-flashsize(gndx0, lax0)
