-### Desktop Linux hidden-window fallback
-
-On Wayland (seen on ChromeOS Linux) a window created with `show: false` can sit
-forever without a single compositor frame: the renderer loads and runs, but
-`ready-to-show` never fires, so the window is never shown and the app looks like
-it did not start while every process is alive. `showWindowWhenReady`
-(`packages/desktop/src/window/show-when-ready.ts`) shows the main window when
-the document finishes loading if the event has not arrived. The fallback is
-Linux-only; macOS and Windows keep waiting for `ready-to-show`.

-Run the startup regression on Linux with an isolated display:

-```bash
-xvfb-run -a npm run test:e2e:window-startup --workspace=@getpaseo/desktop

+# Native iOS text geometry regression
+
+Run on the Namespace Mac with a fresh simulator development build. Use the PID
+returned by `xcrun simctl launch <your-task-simulator-UDID> sh.paseo.debug`.
+Attach only to your task's app, while no device replay is running:
+
+```sh
+PASEO_NATIVE_TEXT_REFLOW_PID=12345 \
+PASEO_NATIVE_TEXT_REFLOW_LOG=/Volumes/devbox/workspace/native-text-reflow.log \
+bash packages/app/e2e/mobile/native-text-reflow/ios.sh
+```
+
+The probe constructs the installed `RNUITextView`, fills its real UIKit text view,
+and resizes its content container from 500 to 240 and back to 500 points. It
+asserts the inner frame follows both widths and the same selection survives.
+It then recycles the view the way Fabric's pool does and remounts it 30 points
+wider and at the same size; the inner frame must still match the container.
+A zeroed frame on recycle comes back 30 or 0 points wide. This assertion checks
+the intermediate recycled geometry; it does not reproduce visible clipping in a
+mounted Fabric paragraph or exercise the subsequent `drawRect` call.
+It uses public UIView/UITextView operations, without mocking React Native.
+LLDB detaches after the probe. An assertion failure or evaluation error fails the
+shell command; the log distinguishes them.
+
+This covers native container resizing and selection retention. It does not cover
+Fabric event delivery, chat row height, reader anchoring, or the on-screen copy
+menu. Those require the real chat journey: read an older multiline response,
+open/close Explorer, resize/rotate, inspect complete paragraphs and bullets,
+retain expanded/collapsed details, and check a stationary reader's position.
+Accessibility exposes full text even when glyphs are clipped, so a text wait
+alone does not verify that journey.

-# Android workspace memory diagnostic
-
-Supplemental reproduction for [#4408](https://github.com/getpaseo/paseo/issues/4408), using the production 0.11.2 APK on an Android 16 emulator. This tests an adapted failure: opening the sidebar with 800 projects, each containing one workspace, produced a `LOW_MEMORY` exit after 66–90 seconds. It does not reproduce the reported 18-second cold-start ANR or establish its cause.
-
-Before running:
-
-- Use a dedicated emulator with the production APK installed and notifications permission settled. Bind the agent-device session to that emulator before running.
-- Pair the app with an isolated daemon containing 800 active workspaces, each in its own project. Use Project grouping and leave projects expanded. The observed fixture used existing directories inside a Git checkout, with workspace titles permuted by `(index * 317) % 800`, no agents, and no terminals.
-- Record the daemon revision, emulator RAM and Java heap settings, and the project/workspace distribution. Device memory pressure controls whether Android kills the app.
-
-Run from the repository root with the agent-device session, Android serial, and an artifact directory:
-
-```sh
-node packages/app/e2e/mobile/workspace-memory/android.mjs workspace-memory emulator-5556 .dev/workspace-memory
-```
-
-The test cold-starts the paired app, opens its sidebar, samples memory and the process ID every five seconds for two minutes, and verifies that closing the sidebar responds. A process exit or restart fails the assertion. Memory, exit records, and logs stay in the supplied artifact directory.
-
-Control: repeat with 800 workspaces grouped into one project. That distribution survived the two-minute automated check and responded to closing the sidebar, with total PSS near 300 MB. The project-per-workspace fixture reached about 2.5 GB PSS before Android recorded `LOW_MEMORY`; its Java heap rose and fell rather than showing the reporter's full-heap ANR. Neither result proves that shared collators would fix the report.
-
-This diagnostic is deliberately outside CI and contains no production change.
