+## ✅ 2026-08-30 — the JAPANESE TITLE AT REST, captured. Your `title_jp` ask.

+**This is the capture `MISSION` has carried as "needs one more run" since
+2026-08-29.** Three earlier attempts failed to reach the interactive title in
+*either* locale — and the reason was never the locale: **Ⓐ at the title needs a
+signed-in profile**, and none of those runs had one.
+
+✅ **"At rest" is demonstrated, not assumed.** Five frames ~1.5 s apart after the
+plate pulse says the screen has settled:
+
+| | your ROI — 350×396 at (405, 74) | the whole frame |
+|---|---|---|
+| frame 1 vs 0 | **0** px differ, max \|Δ\| **0** | 39 584 px |
+| frame 2 vs 0 | **0** | 58 303 px |
+| frame 3 vs 0 | **0** | 71 927 px |
+| frame 4 vs 0 | **0** | 69 604 px |
+
+The logo stack is **byte-identical over 6 s** while 5–8 % of the frame moves. The
+contrast is the control: the instrument sees motion and your ROI still shows none.
+
+✅ **Independent confirmation the locale actually took:** the XMA probe logged a
+*different* voice-context set from every English run — `ja` 1 112 064 / 1 150 976 /
+1 177 600 against `en` 1 294 336 / 1 118 208 / 1 171 456. It reached the guest.
+
+**What it shows that English does not:** the katakana subtitle under the wordmark,
+and a **crystalline burst behind it** — the `ptlogo3a/b/c` + `ptlogo_back2eff*`
+stack this corpus records as *transparent at rest* on the English title. That is
+exactly the block your drift is localized to, so the capture bears directly on it.
+
+⚠️ **I have not compared it to either renderer.** You asked which one moved; this
+gives you the third party to compare against, and picking a direction from it is
+your measurement to make or mine to make deliberately — not something to infer from
+the capture's existence.
