Proof of 2026-05-05 WR
══════════════════════

Notation: if Nth -> a, then we write pN = a.

✅「median {p5, p4, p3} = 1」 implies

(1) both 0 and 1 are in {p5, p4, p3}.

A fortiori, 0 = p5 | p4 | p3.

(2) We claim that indeed 0 = p4.

------------------------------

For, if 0 = p5, then we cannot match ✅「⟨ ▧ ▢ ▢ − − − ⟩, ▧ ≥ Σ▢」. Else if 0 = p3:

then ✅「{p3, p2, p1} = ? + {0,1,2}」 implies {p3, p2, p1} = {0,1,2}:

We cannot match this and (1) at the same time, which is a contradiction.

------------------------------

We have verified (2) and get

In view of (1), we have 1 = p5 or p3:

If it is p5, then we cannot match ✅「⟨ ▧ ▢ ▢ − − − ⟩, ▧ ≥ Σ▢」. Therefore, it is p3.

Now, to match ✅「{p3, p2, p1} = ? + {0,1,2}」, we need

(3) {p2, p1} = {2,3}.

In view of ✅「Sim⟨ ⁵ᵗʰ5 ⁴ᵗʰ4 ³ʳᵈ1 ²ⁿᵈ0 ¹ˢᵗ2 ⁰ᵗʰ3 ⟩ ≤ 1」, as we already have an agreed positional digit 1=p3, to match this pattern we cannot have 2=p1. Therefore, we have
