minimal face → feasible enumerated candidate
Penrose algebra closes for every input, rank, and finite constraint count under nonempty-feasibility assumptions.
dP/df = dP/dw = I-A†A
Both parameter paths receive gradients; learned null-space choice is load-bearing and hard-feasible.
error ≤ (n+1)·base error
An independent Euclidean-projection candidate proof transfers underlying density while C1 preserves adherence.
Paper-spec width-200 Scenario A: five seeds, 50,000 epochs, mean MSE 0.00299 versus 0.0020±0.0032, zero CAffNet violations. Dimension-matched solver and non-monotone width sweep are retained with their limitations, not promoted into universal evidence.
