+## R1 housekeeping — `tools/stale-instrument` was run, and the answer is "none"

+This iteration improved an instrument (the UI draw logger gained render-target,
+resolve and pixel-shader-constant fields), so R1 requires asking what that
+instrument had killed.

+**None of the eight re-open by this change.** All eight are about the *screenshot*
+harness — polling cadence, `x11grab` latency, the title/plate frame classifier,
+the locale runs — and the draw logger is a different instrument that none of them
+ever used. Recorded rather than left silent, because "I ran it and nothing
+changed" and "I did not run it" are indistinguishable in a corpus otherwise.

+The claims this capture *does* re-open are the four `render-vs-capture` and
+`our-reader` entries around the splashes, and they are addressed in the
+refutation section above rather than by the tool.

 ## What is NOT settled here
 
 * **Splash A's step size** — its rising run straddles dropped frames.
