 - **Incremental Changes:** Work will be broken down into small, logical increments. The Agent will pause after each increment to allow the user to review, commit, and push via their preferred IDE interface (such as Antigravity IDE or Android Studio).
 - **Branching Strategy:** All feature development and AI-assisted coding must target the `develop` branch. Pull requests from `develop` to `main` are used to trigger signed Release builds via GitHub Actions.
 - **Versioning Strategy:** The `version.properties` file in the project root is the source of truth for the app's version. To avoid `BuildConfig` instability in experimental environments, a manual `VersionInfo.kt` object must also be maintained in sync with this file. Before any code is merged into `main` for a release, the AI Agent must verify and update `VERSION_NAME` and `VERSION_CODE` in both `version.properties` and `app/src/main/java/com/festerhead/cygnusplayer/VersionInfo.kt`. The GitHub Action will use `version.properties` to automatically publish a public Release.
+- **Pre-PR Branch Sync Protocol:** Before opening a pull request from `develop` to `main` for a new release, `main` must be merged into `develop` (`git checkout develop; git merge main`) to ensure `develop` is up-to-date with `main` before pushing. This prevents GitHub from requiring a secondary "Update branch" merge commit and ensures a single PR build runs.
 - **Static Analysis:** The Agent must run `analyze_file` (IDE Inspections) on every modified file to identify and resolve unused code, deprecations, and style issues before task completion.
 - **Documentation Standards:** Every new class, interface, method, and function must include proper KDoc documentation. KDoc must clearly explain the purpose, parameters (`@param`), and return values (`@return`). For Room entities, explain the role of each column.
 - **AI Commit Messages:** The user will utilize their preferred IDE's AI-generated commit message feature (such as Antigravity IDE or Android Studio).

 ## [Unreleased]
 
+## [1.0.4] - 2026-08-11
+
+### Added
+
+- Added `.markdownlintignore` configuration ignoring AI artifact files (`implementation_plan.md` and `walkthrough.md`).
+
+### Changed
+
+- Refined PowerShell aliases (`ctest`, `crun`, `cdebug`) in `README.md` to use the `-Dadb.device.serial` Gradle property, ensuring only the intended target device is used during instrumented tests when multiple devices are connected.
+- Updated PowerShell aliases to include an `adb uninstall` step and support dual-target switching between physical phone and emulator.
+- Relaxed `DatabaseStressTest` query thresholds (Single: 10ms, Folder: 50ms) to ensure stability on physical hardware under background OS load.
+
+### Fixed
+
+- Display configured Music Root Folder on Settings screen with URL decoding and marquee formatting ([#3](https://github.com/FesterHead/cygnus-player/issues/3)).
+- Resolved home screen widget metadata update delay on initial add during active playback via `REQUEST_WIDGET_UPDATE` broadcast ([#4](https://github.com/FesterHead/cygnus-player/issues/4)).
+- Display playing triangle indicator on playlist screen for active playlist and position active playlist at top of history list ([#5](https://github.com/FesterHead/cygnus-player/issues/5)).

+To maintain "Zero-Manual-Discovery" of bugs while bypassing framework-level environmental issues and supporting multi-device environments (Phone vs. Emulator), use the following PowerShell aliases.
 
 ### 1. Alias Setup
 
-Add these to your PowerShell `$PROFILE` for maximum productivity:
+To obtain your target device serial numbers, run `adb devices` in your terminal:
+
+```powershell
+adb devices
+# Output example:
+# List of devices attached
+# 44201JEKB09382    device
+# emulator-5554     device
+```
+
+Replace `"44201JEKB09382"` with your physical device's serial number, or pass `"emu"` to target the local emulator (`emulator-5554`).
+
+Add these helper functions to your PowerShell `$PROFILE`:
 
 ```powershell
