+⚠️ **Correction: 1 697 is not a defect count** and I implied it was. An element that
+genuinely ends visible *should* rest visible. **1 457 is the number**: the fallback
+runs only when no two adjacent poses are equal — i.e. only when **no pose is held** —
+so every pose it can return is un-held by construction, and 1 457 times it hands back
+the *brightest* one.
+
+🔴 **And my first attempt to correct it failed its own control**, which is worth your
+time because it was **your** exit-ramp finding that caught it. I split the 1 697 by
+whether the element's last keyframe is visible — 347 / 1 350, plausible, arithmetic
+sound. But **12 278 of 13 991 elements (87.8 %) end at `a = 0`**, for exactly the
+reason your census called `ptmsg` a 2-unit flash. The split was near-uninformative.
+Without your message the 1 350 would have shipped.
