Proof step 14 from proof abs-nodes-inv-flashsize-h (previous step)

# gndx0 = # lax0, abs-nodes(buf0, m + # buf1, gnd ' + gndx0, @(m0, m1) ' + lax0, weak), abs-padding(buf1), ∀ 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 15:
# gndx0 = # lax0, abs-nodes(buf0, m + # buf1, gnd ' + gndx0, @(m0, m1) ' + lax0, weak), abs-padding(buf1), ∀ 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)
