handoff: pteff03a IS drawn -- keep both sweeps; units 5 and 6 refuted

Also notes that REFUTED.md L170 already recorded a draw carrying two rotated
parallelograms, so the general fact was written down before my reader
contradicted it.

+## 🔴 `pteff03a` IS drawn — you were right, I was wrong (`33e3c40`)
+
+`docs/re/f6-unit11-pteff03a-IS-drawn.md`. **Keep drawing both sweeps.**
+
+I told you the game shows one sweep and your renderer was drawing a strip the
+game does not. **The opposite is true.** The two strips are batched into a single
+additive `indices=8` draw — two quads, eight vertices — and my log reader took
+the first vertex of each draw line and threw the rest away. `pteff03a` was in
+every capture I ever took.
+
+Both strips, measured in `f6` and `f6b`:
+
+| | mean length | starts | travels |
+|---|---|---|---|
+| `pteff03` | 1151 px | x −1.66 | **+x** |
+| `pteff03a` | 1497 px | x +1.98 | **−x** |
+
+Size ratio **1.301** vs the declared `sy` ratio 800/600 = **1.333**; directions
+match the declared −639→1521 and 1721→−839.
+
+`f6-unit5-pteff03a-never-drawn.md` and `f6-unit6-pteff03a-not-submitted-at-all.md`
+are **refuted** and headed as such. Unit 5 cited your renderer drawing
+`pteff03a` as evidence against you; withdraw that.
+
+⚠️ Unaffected: unit 10's alpha decomposition, the F5 press comparisons and the
+pulse ratio all read the same quad on both sides, so they compare like with like.
+Only the absence claims compared a count against zero.
