 # StatusBarTweak
 
-StatusBarTweak is an Xposed/LSPosed module for Samsung SystemUI. It focuses on
-making the status bar, lockscreen, and Always On Display more configurable while
-still keeping Samsung's own icons and visual style where possible.
+StatusBarTweak is an Xposed/LSPosed module originally built for Samsung
+SystemUI. It focuses on making the status bar, lockscreen, and Always On
+Display more configurable while still keeping the system's own icons and visual
+style where possible.
 
-The project is currently tested only on a Samsung Galaxy Z Fold5 running One UI
-8.0 / Android 16. Expect device- and One UI-version-specific behaviour.
+The project is physically tested only on a Samsung Galaxy Z Fold5 running One UI
+8.0 / Android 16. Other SystemUI builds have emulator-tested support as shown
+in the compatibility matrix.
+
+## AI Assistance
+
+This project was developed with help from AI-assisted coding tools. The design
+decisions, physical device testing, and final behaviour are still manually reviewed.
 
 ## What It Does
 
-- Custom status bar layout for the unlocked screen, lockscreen, and AOD.
+- Custom status bar layout for the unlocked screen, lockscreen, and AOD where
+  supported by the SystemUI build.
 - Independent placement of clock, carrier text, notification icons, status
   icons, and Samsung status chips.
 - Separate notification display handling for Samsung's cards, icons, and dot
@@ -41,31 +49,64 @@ It also supports lightweight markup:
 - Pipe alignment with `|`, useful for aligning split clock rows around a camera
   cutout.
 - Colour variants and reverse Polish notation colour math for light/dark status
-  bar states, for example `color(#batterybar 1.2 * ; invRGB 0.5 *RGB)`.
+  bar states, for example `color(#batterybar 1.2 *RGB ; #batterybar 0.5 *RGB)`, which uses the batterybar's dynamic colour as its base. For the bright tint, it brightens it up some more, while for the dark tint, it is darkened.
 
 The in-app clock page has the full syntax help and examples.
 
 ## Requirements
 
-- A rooted Samsung device.
-- A modern Xposed implementation such as LSPosed.
+- A rooted Android 14+ device or emulator. Actual feature support depends on
+  the SystemUI implementation; see the compatibility matrix.
+- A modern Xposed implementation such as LSPosed or another libxposed-compatible runtime.
 - Xposed API 101 or newer.
-- A Samsung/One UI version close to One UI 8.0 / Android 16.
+- SystemUI access for the module scope.
 
-This module hooks Samsung SystemUI internals. It is not expected to work on
-non-Samsung SystemUI, and updates to One UI may require fixes.
+The module is developed and manually tested on a Samsung Galaxy Z Fold5 running
+One UI 8.0 / Android 16. Non-Samsung builds have emulator-tested support as
+shown below, but hardware-dependent behavior remains experimental unless it has
+also been verified on physical hardware.
 
 ## Device Compatibility
 
-StatusBarTweak is Samsung-specific in its current form. Some lower-level ideas,
-such as drawing a custom battery bar or parsing custom clock text, could be
-ported elsewhere. The layout engine itself depends on Samsung's SystemUI,
-lockscreen, AOD service, notification display modes, status icons, and status
-chip implementation.
+Some behavior cannot be fully verified on emulators. Emulator testing can still
+verify whether hooks load, whether SystemUI stays stable, whether settings apply,
+whether excessive background work appears in logs, and whether the steady state
+looks the way it should.
 
-Plain Android or other OEM skins would need separate hooks and probably a
-different source-collection layer. They should be treated as unsupported rather
-than untested-compatible.
+`⚠️ Experimental` means best-effort support exists, but the emulator cannot
+expose the required hardware or state for real verification.

-## Development Note
+## Test Harness
 
-This project has been coded with the help of AI as an implementation aid. The
-design decisions, device testing, and final behaviour are still manually
-reviewed.
+The repository also includes a small companion app for compatibility testing.
+It is not required for normal use of the module. It creates repeatable
+statusbar scenarios such as opaque, transparent, fullscreen, privacy-indicator,
+and notification states:
+
+```bash
+./gradlew :test-harness:assembleDebug
+adb install -r test-harness/build/outputs/apk/debug/test-harness-debug.apk
+adb shell am start -n se.ajpanton.statusbartweak.harness/.MainActivity
+```
+
+Automation can launch scenarios directly:
+
+```bash
+adb shell am start -n se.ajpanton.statusbartweak.harness/.ScenarioActivity --es scenario fullscreen_landscape
+adb shell am start -n se.ajpanton.statusbartweak.harness/.MainActivity --es command post_normal
+```
+
+Useful scenario values include `opaque_light`, `opaque_dark`, `transparent`,
+`fullscreen_portrait`, `fullscreen_landscape`, `camera`, `microphone`, and
+`camera_microphone`.
+
+Useful command values include `post_normal`, `post_ongoing`, `post_grouped`,
+`update`, `start_chronometer`, `start_churn`, `stop_churn`, `start_media`,
+`start_foreground`, `stop_service`, and `clear`.
+
+Battery charging state is controlled by Android system commands rather than by
+the harness APK:
+
+```bash
+adb shell cmd battery set status 2
+adb shell cmd battery set level 80
+adb shell cmd battery reset
+```
