         also what Iris's phone reports have shown all along. The fix
         matters for any device that falls back to GLES, which is why it is
         not just an emulator convenience.
+      - **Appearance testing on Android is back.** `build-apk.sh debug
+        --abi x86_64 --features "transcript-screen bench force-gles"` on
+        this checkout's AVD draws the transcript legibly --
+        `docs/bench/p1a-2026-09-06/iris-emulator-gles-fixed.png` -- so
+        P1b onwards can be checked here rather than only on the desktop
+        backend or Iris's phone.
+      **2026-09-06: the move slot has one owner.** IRIS_TODO's open
+      "a wrapped transcript row trips `reposition`'s debug assert" is
+      fixed rather than suppressed. `mov` accumulates a delta on a
+      widget's move slot and `reposition` overwrote it, and both
+      legitimately land on one widget in one frame: `List::place`'s
+      Bottom-known branch offers a row a same-size box that has *moved*
+      (`mov`), then corrects the placement inside it when the row's
+      cached height no longer matches what the row reports
+      (`reposition`) -- measured with a probe on the `.wrap(true)` repro:
+      `h=1604.7 height=548.7`, the row's own draw having updated
+      `active.size` without the list's height cache. The slot now means
+      `move_applied + repositioned` (both on `ActiveData`), so
+      `reposition` adds the move instead of dropping it and stays
+      idempotent, and the old assert is replaced by a `debug_assert_eq!`
+      that nothing *but* those two ever wrote the slot. Test:
+      `a_widget_moved_by_its_parent_and_then_placed_inside_it_lands_at_the_placement`
+      (`layout_tests.rs`), which draws the child at the offered position
+      rather than the placement without the fix. Checks: `cargo fmt --all
+      --check` clean, `cargo clippy --workspace --all-targets`
+      warning-free, `cargo test --workspace` 86 (iris, +1) + 13
+      (iris-core) + 31 (transcript-ui), the `.wrap(true)` repro drawing
+      correctly, and an emulator bench run with assertions live and no
+      abort (`2438 frames over 147.7s, p50 27.2ms`).
