Subject: [PATCH 014/954] Implement navigation framework

Add a bottom navigation bar and a top app bar to the main application
structure. Create placeholder screens for the home, search, profile and settings sections to allow for testing the navigation flow between them.

This setup provides the foundational UI structure for future feature
development.

+ *
+ * How it works:
+ * - The NavigationBar is part of Material3 design.
+ * - Each [NavigationBarItem] represents a screen and has: → An icon → A text label → A route to
+ *   navigate to when clicked
+ * - The bar highlights the active route using [selected].
+ * - Navigation is handled by the shared [NavHostController].
+ *
+ * How to add a new tab:
+ * 1. Add a new route constant to [NavRoutes].
+ * 2. Add a new [BottomNavItem] to the `items` list below.
+ * 3. Add a corresponding `composable()` entry to [NavGraph].
+ *
+ * How to remove a tab:
+ * - Simply remove it from the `items` list below.

+ * AppNavGraph
+ *
+ * This file defines the navigation graph for the app using Jetpack Navigation Compose. It maps
+ * navigation routes (defined in [NavRoutes]) to the composable screens that should be displayed
+ * when the user navigates to that route.
+ *
+ * How it works:
+ * - [NavHost] acts as the navigation container.
+ * - Each `composable()` inside NavHost represents one screen in the app.
+ * - The [navController] is used to navigate between routes.
+ *
+ * Example usage: navController.navigate(NavRoutes.PROFILE)
+ *
+ * To add a new screen:
+ * 1. Create a new composable screen (e.g., MyNewScreen.kt) inside ui/screens/.
+ * 2. Add a new route constant to [NavRoutes] (e.g., const val MY_NEW_SCREEN = "my_new_screen").
+ * 3. Add a new `composable()` entry below with your screen function.
+ * 4. (Optional) Add your route to the bottom navigation bar if needed.
+ *
+ * This makes it easy to add, remove, or rename screens without breaking navigation.

Subject: [PATCH 015/954] Implement navigation framework

Add a bottom navigation bar and a top app bar to the main application
structure. Create placeholder screens for the home, search, profile and settings sections to allow for testing the navigation flow between them.

This setup provides the foundational UI structure for future feature
development.

+ * 3. Add a new `composable()` entry below with your screen function.
+ * 4. (Optional) Add your route to the bottom navigation bar if needed.

+ * ### Removing a screen:
+ * 1. Remove the `const val` for the screen's route.
+ * 2. Remove the route and its composable from `NavGraph.kt`.

Subject: [PATCH 017/954] Remove template test files with missing components

Delete generated test files that were failing due to referencing
removed composable components. The tests were checking for UI elements
from the original project template that are no longer present in the
application after implementing the custom navigation framework.

This eliminates false CI failures and removes outdated test
dependencies on template code that has been replaced.

 /**
- * BottomNavBar
+ * BottomNavBar - Main navigation bar component for SkillBridge app
  *
- * This composable defines the app’s bottom navigation bar. It allows users to switch between key
- * screens (Home, Skills, Profile, Settings) by tapping icons at the bottom of the screen.
+ * A Material3 NavigationBar that provides tab-based navigation between main app sections.
+ * Integrates with RouteStackManager to maintain proper navigation state and back stack handling.
  *
- * How it works:
- * - The NavigationBar is part of Material3 design.
- * - Each [NavigationBarItem] represents a screen and has: → An icon → A text label → A route to
- *   navigate to when clicked
- * - The bar highlights the active route using [selected].
- * - Navigation is handled by the shared [NavHostController].
+ * Features:
+ * - Shows 4 main tabs: Home, Skills, Profile, Settings
+ * - Highlights currently selected tab based on navigation state
+ * - Resets route stack when switching tabs to prevent deep navigation issues
+ * - Preserves tab state with saveState/restoreState for smooth UX
+ * - Uses launchSingleTop to prevent duplicate destinations
  *
- * How to add a new tab:
- * 1. Add a new route constant to [NavRoutes].
- * 2. Add a new [BottomNavItem] to the `items` list below.
- * 3. Add a corresponding `composable()` entry to [NavGraph].
+ * Usage:
+ * - Place in main activity/screen as persistent bottom navigation
+ * - Pass NavHostController from parent composable
+ * - Navigation routes must match those defined in NavRoutes object
  *
- * How to remove a tab:
- * - Simply remove it from the `items` list below.
+ * Adding a new tab:
+ * 1. Add new BottomNavItem to the items list with label, icon, and route
+ * 2. Ensure corresponding route exists in NavRoutes
+ * 3. Add route to RouteStackManager.mainRoutes if needed
+ * 4. Import appropriate Material icon
+ *
+ * Note: Tab switching automatically clears and resets the navigation stack

- * TopBar composable
+ * TopAppBar - Reusable top navigation bar component for SkillBridge app
  *
- * Displays a top app bar with:
- * - The current screen's title
- * - A back arrow button if the user can navigate back
+ * A Material3 TopAppBar that displays the current screen title and handles back navigation.
+ * Integrates with both NavController and RouteStackManager for intelligent navigation behavior.
  *
- * @param navController The app's NavController, used to detect back stack state and navigate up.
+ * Features:
+ * - Dynamic title based on current route (Home, Skills, Profile, Settings, or default
+ *   "SkillBridge")
+ * - Smart back button visibility (hidden on Home screen, shown when navigation is possible)
+ * - Dual navigation logic: main routes navigate to Home, secondary screens use custom stack
+ * - Preserves navigation state with launchSingleTop and restoreState
+ *
+ * Navigation Behavior:
+ * - Main routes (bottom nav): Back button goes to Home and resets stack
+ * - Secondary screens: Back button uses RouteStackManager's previous route
+ * - Fallback to NavController.navigateUp() if stack is empty
+ *
+ * Usage:
+ * - Place in main activity/screen layout above content area
+ * - Pass NavHostController from parent composable
+ * - Works automatically with routes defined in NavRoutes object
+ *
+ * Modifying titles:
+ * 1. Add new route case to the title when() expression
+ * 2. Ensure route constant exists in NavRoutes object
+ * 3. Update RouteStackManager.mainRoutes if it's a main route
+ *
+ * Note: Requires @OptIn(ExperimentalMaterial3Api::class) for TopAppBar usage

 /**
- * AppNavGraph
+ * AppNavGraph - Main navigation configuration for the SkillBridge app
  *
- * This file defines the navigation graph for the app using Jetpack Navigation Compose. It maps
- * navigation routes (defined in [NavRoutes]) to the composable screens that should be displayed
- * when the user navigates to that route.
+ * This file defines all navigation routes and their corresponding screen composables. Each route is
+ * registered with the NavHost and includes route tracking via RouteStackManager.
  *
- * How it works:
- * - [NavHost] acts as the navigation container.
- * - Each `composable()` inside NavHost represents one screen in the app.
- * - The [navController] is used to navigate between routes.
+ * Usage:
+ * - Call AppNavGraph(navController) from your main activity/composable
+ * - Navigation is handled through the provided NavHostController
  *
- * Example usage: navController.navigate(NavRoutes.PROFILE)
+ * Adding a new screen:
+ * 1. Add route constant to NavRoutes object
+ * 2. Import the new screen composable
+ * 3. Add composable() block with LaunchedEffect for route tracking
+ * 4. Pass navController parameter if screen needs navigation
  *
- * To add a new screen:
- * 1. Create a new composable screen (e.g., MyNewScreen.kt) inside ui/screens/.
- * 2. Add a new route constant to [NavRoutes] (e.g., const val MY_NEW_SCREEN = "my_new_screen").
- * 3. Add a new `composable()` entry below with your screen function.
- * 4. (Optional) Add your route to the bottom navigation bar if needed.
+ * Removing a screen:
+ * 1. Delete the composable() block
+ * 2. Remove unused import
+ * 3. Remove route constant from NavRoutes (if no longer needed)
  *
- * This makes it easy to add, remove, or rename screens without breaking navigation.
+ * Note: All screens automatically register with RouteStackManager for back navigation tracking

+ * MyBookingsScreen - Displays the user's bookings in a scrollable list.
+ *
+ * This composable renders the "My Bookings" page, including:
+ * - A top app bar with navigation and title.
+ * - A bottom navigation bar for main app sections.
+ * - A vertical list of booking cards, each showing tutor, subject, price, duration, date, and rating.
+ * - A "details" button for each booking, invoking [onOpenDetails] when clicked.
+ *
+ * UI Structure:
+ * - Uses [Scaffold] to provide top and bottom bars.
+ * - Booking data is provided by [MyBookingsViewModel] via StateFlow.
+ * - Each booking is rendered using a private [BookingCard] composable.
+ *
+ * Behavior:
+ * - The list updates automatically when the view model's data changes.
+ * - Handles empty state by showing no cards if there are no bookings.
+ * - [onOpenDetails] is called with the selected [BookingCardUi] when the details button is pressed.
+ *
+ * @param vm The [MyBookingsViewModel] providing the list of bookings.
+ * @param navController The [NavHostController] for navigation actions.
+ * @param onOpenDetails Callback invoked when the details button is clicked for a booking.
+ * @param modifier Optional [Modifier] for the root composable.

Subject: [PATCH 070/954] fix(bottom-nav, bookings): move nav test tags to
 NavigationBarItem and add Bookings tab

- Move  from Icon to  so Espresso/Compose tests
  reliably find navigation items (prevents semantics merging/hiding).

- Introduce per-item  to avoid undefined variable errors and apply test tags
  for , , and .
- Ensure  is used and an appropriate icon (Star) is set for Bookings.
- Keep  top/bottom bar test tags intact so UI tests continue to locate

Subject: [PATCH 072/954] feat(new-skill): add setError and invalid subject
 message

Add setError to compute and set per-field validation messages from the UI state.
Add "You must choose a subject" message for empty subject and ensure subject
validation is included in setError. Also preserve existing price/field validation.

 /**
- * MyBookingsScreen - Displays the user's bookings in a scrollable list.
+ * Renders the **My Bookings** page.
  *
- * This composable renders the "My Bookings" page, including:
- * - A top app bar with navigation and title.
- * - A bottom navigation bar for main app sections.
- * - A vertical list of booking cards, each showing tutor, subject, price, duration, date, and
- *   rating.
- * - A "details" button for each booking, invoking [onOpenDetails] when clicked.
+ * ### Responsibilities
+ * - Shows a scrollable list of user bookings.
+ * - Provides the shared top app bar and bottom navigation.
+ * - Emits a callback when the “details” button on a card is pressed.
  *
- * UI Structure:
- * - Uses [Scaffold] to provide top and bottom bars.
- * - Booking data is provided by [MyBookingsViewModel] via StateFlow.
- * - Each booking is rendered using a private [BookingCard] composable.
+ * ### Data flow
+ * - Collects [MyBookingsViewModel.items] and renders each item via [BookingCard].
+ * - The list uses stable keys ([BookingCardUi.id]) to support smooth updates.
  *
- * Behavior:
- * - The list updates automatically when the view model's data changes.
- * - Handles empty state by showing no cards if there are no bookings.
- * - [onOpenDetails] is called with the selected [BookingCardUi] when the details button is pressed.
+ * ### Testing hooks
+ * - Top bar wrapper: [MyBookingsPageTestTag.TOP_BAR_TITLE]
+ * - Bottom nav wrapper: [MyBookingsPageTestTag.BOTTOM_NAV]
+ * - Each booking card: [MyBookingsPageTestTag.BOOKING_CARD]
+ * - Each details button: [MyBookingsPageTestTag.BOOKING_DETAILS_BUTTON]
  *
- * @param vm The [MyBookingsViewModel] providing the list of bookings.
- * @param navController The [NavHostController] for navigation actions.
- * @param onOpenDetails Callback invoked when the details button is clicked for a booking.
- * @param modifier Optional [Modifier] for the root composable.
+ * ### Empty state
+ * - When [MyBookingsViewModel.items] is empty, no cards are rendered (dedicated empty UI can be
+ *   added later without changing this contract).
  *
- * Usage:
+ * @param vm ViewModel that exposes the list of bookings as a `StateFlow<List<BookingCardUi>>`.
+ * @param navController Host controller for navigation used by the shared bars.
+ * @param onOpenDetails Invoked with the associated [BookingCardUi] when a card’s “details” is
+ *   tapped.
+ * @param modifier Optional root [Modifier].

Subject: [PATCH 077/954] Add manual APK generation workflow

Create a GitHub Actions workflow that generates APK files on demand
through manual triggering. This allows team members to build release
artifacts without going through the full CI pipeline, useful for
testing and demonstration purposes.

The workflow produces signed APKs that can be directly installed on
test devices, streamlining the development and QA processes.

Subject: [PATCH 083/954] Add push trigger for testing APK workflow

Temporarily add push trigger to the APK generation workflow to enable
testing before merging into main. This allows the workflow to execute
on branch push, making it visible in GitHub Actions for verification
and debugging purposes.

The push trigger will be removed once the workflow is validated and
ready for production use with manual triggers only.

Subject: [PATCH 097/954] Remove temporary push trigger from APK workflow

Remove the push trigger that was temporarily added for testing the APK
generation workflow. The workflow now only supports manual triggering
as intended for production use. This change follows successful
validation of the workflow functionality during testing.

The workflow is ready for use in the main branch and can be triggered
manually through GitHub Actions when APK builds are needed.

Subject: [PATCH 112/954] ui(bookings): decouple screen chrome; add bar
 test-tags; fix tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove Scaffold/top & bottom bars from MyBookingsScreen → pure list UI.
- Host bars in app shell/TestHost to avoid duplicate chrome.
- Add tags inside components:
  - TopAppBar → TOP_BAR_TITLE
  - BottomNavBar → BOTTOM_NAV, NAV_HOME, NAV_BOOKINGS, NAV_PROFILE
- Update MyBookingsRobolectricTest to use TestHost and assert bar tags.
- No data/logic changes; previews unchanged.

Subject: [PATCH 115/954] Add manual APK generation workflow

Create a GitHub Actions workflow that generates APK files on demand
through manual triggering. This allows team members to build release
artifacts without going through the full CI pipeline, useful for
testing and demonstration purposes.

The workflow produces signed APKs that can be directly installed on
test devices, streamlining the development and QA processes.

Subject: [PATCH 118/954] Add push trigger for testing APK workflow

Temporarily add push trigger to the APK generation workflow to enable
testing before merging into main. This allows the workflow to execute
on branch push, making it visible in GitHub Actions for verification
and debugging purposes.

The push trigger will be removed once the workflow is validated and
ready for production use with manual triggers only.

Remove the push trigger that was temporarily added for testing the APK
generation workflow. The workflow now only supports manual triggering
as intended for production use. This change follows successful
validation of the workflow functionality during testing.

The workflow is ready for use in the main branch and can be triggered
manually through GitHub Actions when APK builds are needed.

Subject: [PATCH 134/954] Add manual APK generation workflow

Create a GitHub Actions workflow that generates APK files on demand
through manual triggering. This allows team members to build release
artifacts without going through the full CI pipeline, useful for
testing and demonstration purposes.

The workflow produces signed APKs that can be directly installed on
test devices, streamlining the development and QA processes.

Subject: [PATCH 137/954] Add push trigger for testing APK workflow

Temporarily add push trigger to the APK generation workflow to enable
testing before merging into main. This allows the workflow to execute
on branch push, making it visible in GitHub Actions for verification
and debugging purposes.

The push trigger will be removed once the workflow is validated and
ready for production use with manual triggers only.

Subject: [PATCH 141/954] Remove temporary push trigger from APK workflow

Remove the push trigger that was temporarily added for testing the APK
generation workflow. The workflow now only supports manual triggering
as intended for production use. This change follows successful
validation of the workflow functionality during testing.

The workflow is ready for use in the main branch and can be triggered
manually through GitHub Actions when APK builds are needed.

Subject: [PATCH 142/954] Add manual APK generation workflow

Create a GitHub Actions workflow that generates APK files on demand
through manual triggering. This allows team members to build release
artifacts without going through the full CI pipeline, useful for
testing and demonstration purposes.

The workflow produces signed APKs that can be directly installed on
test devices, streamlining the development and QA processes.

Subject: [PATCH 145/954] Add push trigger for testing APK workflow

Temporarily add push trigger to the APK generation workflow to enable
testing before merging into main. This allows the workflow to execute
on branch push, making it visible in GitHub Actions for verification
and debugging purposes.

The push trigger will be removed once the workflow is validated and
ready for production use with manual triggers only.

Subject: [PATCH 149/954] Remove temporary push trigger from APK workflow

Remove the push trigger that was temporarily added for testing the APK
generation workflow. The workflow now only supports manual triggering
as intended for production use. This change follows successful
validation of the workflow functionality during testing.

The workflow is ready for use in the main branch and can be triggered
manually through GitHub Actions when APK builds are needed.

Subject: [PATCH 150/954] feat(booking): add FakeBookingRepository & integrate
 repo API into ViewModel/tests/preview

- Implement FakeBookingRepository to satisfy BookingRepository interface and provide
  deterministic demo bookings for tests and previews.
- Update MyBookingsViewModel to accept a BookingRepository and userId, use
  repo.getBookingsByUserId(...) in refresh(), and expose deterministic demo()
  results for previews/tests.
- Update unit and Robolectric tests to construct MyBookingsViewModel with
  FakeBookingRepository and the required user id; adjust TestHost wrappers to
  avoid duplicate test tags.
- Update MyBookingsScreen preview to use the repository-backed ViewModel (calls
  refresh() for realistic data).

BREAKING CHANGE: MyBookingsViewModel constructor now requires a BookingRepository
and a userId. Tests and callers must be updated to pass these arguments.

Subject: [PATCH 151/954] Implement navigation framework

Add a bottom navigation bar and a top app bar to the main application
structure. Create placeholder screens for the home, search, profile and settings sections to allow for testing the navigation flow between them.

This setup provides the foundational UI structure for future feature
development.

+ * This composable defines the app’s bottom navigation bar. It allows users to switch between key

+ *
+ * How it works:
+ * - The NavigationBar is part of Material3 design.
+ * - Each [NavigationBarItem] represents a screen and has: → An icon → A text label → A route to
+ *   navigate to when clicked
+ * - The bar highlights the active route using [selected].
+ * - Navigation is handled by the shared [NavHostController].
+ *
+ * How to add a new tab:
+ * 1. Add a new route constant to [NavRoutes].
+ * 2. Add a new [BottomNavItem] to the `items` list below.
+ * 3. Add a corresponding `composable()` entry to [NavGraph].
+ *
+ * How to remove a tab:
+ * - Simply remove it from the `items` list below.

+ * AppNavGraph
+ *
+ * This file defines the navigation graph for the app using Jetpack Navigation Compose. It maps
+ * navigation routes (defined in [NavRoutes]) to the composable screens that should be displayed
+ * when the user navigates to that route.
+ *
+ * How it works:
+ * - [NavHost] acts as the navigation container.
+ * - Each `composable()` inside NavHost represents one screen in the app.
+ * - The [navController] is used to navigate between routes.
+ *
+ * Example usage: navController.navigate(NavRoutes.PROFILE)
+ *
+ * To add a new screen:
+ * 1. Create a new composable screen (e.g., MyNewScreen.kt) inside ui/screens/.
+ * 2. Add a new route constant to [NavRoutes] (e.g., const val MY_NEW_SCREEN = "my_new_screen").
+ * 3. Add a new `composable()` entry below with your screen function.
+ * 4. (Optional) Add your route to the bottom navigation bar if needed.
+ *
+ * This makes it easy to add, remove, or rename screens without breaking navigation.

Subject: [PATCH 152/954] Implement navigation framework

Add a bottom navigation bar and a top app bar to the main application
structure. Create placeholder screens for the home, search, profile and settings sections to allow for testing the navigation flow between them.

This setup provides the foundational UI structure for future feature
development.

Subject: [PATCH 154/954] Remove template test files with missing components

Delete generated test files that were failing due to referencing
removed composable components. The tests were checking for UI elements
from the original project template that are no longer present in the
application after implementing the custom navigation framework.

This eliminates false CI failures and removes outdated test
dependencies on template code that has been replaced.

 /**
- * BottomNavBar
+ * BottomNavBar - Main navigation bar component for SkillBridge app
  *
- * This composable defines the app’s bottom navigation bar. It allows users to switch between key
- * screens (Home, Skills, Profile, Settings) by tapping icons at the bottom of the screen.
+ * A Material3 NavigationBar that provides tab-based navigation between main app sections.
+ * Integrates with RouteStackManager to maintain proper navigation state and back stack handling.
  *
- * How it works:
- * - The NavigationBar is part of Material3 design.
- * - Each [NavigationBarItem] represents a screen and has: → An icon → A text label → A route to
- *   navigate to when clicked
- * - The bar highlights the active route using [selected].
- * - Navigation is handled by the shared [NavHostController].
+ * Features:
+ * - Shows 4 main tabs: Home, Skills, Profile, Settings
+ * - Highlights currently selected tab based on navigation state
+ * - Resets route stack when switching tabs to prevent deep navigation issues
+ * - Preserves tab state with saveState/restoreState for smooth UX
+ * - Uses launchSingleTop to prevent duplicate destinations
  *
- * How to add a new tab:
- * 1. Add a new route constant to [NavRoutes].
- * 2. Add a new [BottomNavItem] to the `items` list below.
- * 3. Add a corresponding `composable()` entry to [NavGraph].
+ * Usage:
+ * - Place in main activity/screen as persistent bottom navigation
+ * - Pass NavHostController from parent composable
+ * - Navigation routes must match those defined in NavRoutes object
  *
- * How to remove a tab:
- * - Simply remove it from the `items` list below.
+ * Adding a new tab:
+ * 1. Add new BottomNavItem to the items list with label, icon, and route
+ * 2. Ensure corresponding route exists in NavRoutes
+ * 3. Add route to RouteStackManager.mainRoutes if needed
+ * 4. Import appropriate Material icon
+ *
+ * Note: Tab switching automatically clears and resets the navigation stack

Subject: [PATCH 158/954] Add manual APK generation workflow

Create a GitHub Actions workflow that generates APK files on demand
through manual triggering. This allows team members to build release
artifacts without going through the full CI pipeline, useful for
testing and demonstration purposes.

The workflow produces signed APKs that can be directly installed on
test devices, streamlining the development and QA processes.

Subject: [PATCH 161/954] Add push trigger for testing APK workflow

Temporarily add push trigger to the APK generation workflow to enable
testing before merging into main. This allows the workflow to execute
on branch push, making it visible in GitHub Actions for verification
and debugging purposes.

The push trigger will be removed once the workflow is validated and
ready for production use with manual triggers only.

Remove the push trigger that was temporarily added for testing the APK
generation workflow. The workflow now only supports manual triggering
as intended for production use. This change follows successful
validation of the workflow functionality during testing.

The workflow is ready for use in the main branch and can be triggered
manually through GitHub Actions when APK builds are needed.

Subject: [PATCH 177/954] test(bookings): consolidate & add ViewModel + UI
 tests to existing test files

- Add unit test for MyBookingsViewModel.refresh() to assert mapping of Booking -> BookingCardUi
  (duration, price label, date format, id/tutor mapping).
- Merge BookingCard compose interaction test into MyBookingsRobolectricTest to verify rendering
  and details button behavior without creating new test files.
- Expand android instrumentation/compose tests in MyBookingsTest to cover empty state + integration
  scenarios using .

Subject: [PATCH 186/954] SignUp: add surname and levelOfEducation, move
 submit/validation to ViewModel

- Add  to Profile and SignUp UI state.
- Replace  with  across state, events, test tags and UI fields.
- Move validation and submit logic into SignUpViewModel:
  - validate name, surname, email and password.
  - build  by joining trimmed name + surname.
  - call  with levelOfEducation and description (keep other fields as defaults).
- Make SignUpScreen purely UI: dispatches events and observes state (handles submit success via LaunchedEffect).
- Update test tags and placeholders to reflect the field renames.

Subject: [PATCH 191/954] bookings: improve mapping, enforce price format,
 stabilize tests

- Add nested-property reflection helpers (, ) to
   so tutor name and
  subject are extracted when nested inside  /  / .
- Always format hourly price with one decimal () to match test expectations.
- Add  flag to
  and use it in tests to avoid races with the ViewModel's async init.
- Add missing test tag  in
  .
- Update tests to use  and minor cleanup (remove stray import,
  fix unresolved reference).

Subject: [PATCH 192/954] bookings: improve mapping, enforce price format,
 stabilize tests

- Add nested-property reflection helpers (, ) to
   so tutor name and
  subject are extracted when nested inside  /  / .
- Always format hourly price with one decimal () to match test expectations.
- Add  flag to
  and use it in tests to avoid races with the ViewModel's async init.
- Add missing test tag  in
  .
- Update tests to use  and minor cleanup (remove stray import,
  fix unresolved reference).

Subject: [PATCH 198/954] feat(bookings): merge screen+vm, add mapper &
 uiState, expand tests

- Inject BookingRepository; remove demo data
- Add BookingToUiMapper for formatting/localization
- Introduce MyBookingsUiState (Loading/Success/Empty/Error)
- Keep items flow for compatibility
- Replace & expand unit/UI tests

- * Renders the **My Bookings** page.

- * ### Responsibilities
- * - Shows a scrollable list of user bookings.
- * - Provides the shared top app bar and bottom navigation.
- * - Emits a callback when the “details” button on a card is pressed.
- *
- * ### Data flow
- * - Collects [MyBookingsViewModel.items] and renders each item via [BookingCard].
- * - The list uses stable keys ([BookingCardUi.id]) to support smooth updates.
- *
- * ### Testing hooks
- * - Top bar wrapper: [MyBookingsPageTestTag.TOP_BAR_TITLE]
- * - Bottom nav wrapper: [MyBookingsPageTestTag.BOTTOM_NAV]
- * - Each booking card: [MyBookingsPageTestTag.BOOKING_CARD]
- * - Each details button: [MyBookingsPageTestTag.BOOKING_DETAILS_BUTTON]
- *
- * ### Empty state
- * - When [MyBookingsViewModel.items] is empty, no cards are rendered (dedicated empty UI can be
- *   added later without changing this contract).
- *
- * @param vm ViewModel that exposes the list of bookings as a `StateFlow<List<BookingCardUi>>`.
- * @param navController Host controller for navigation used by the shared bars.
- * @param onOpenDetails Invoked with the associated [BookingCardUi] when a card’s “details” is
- *   tapped.
- * @param modifier Optional root [Modifier].

Subject: [PATCH 213/954] feat(profile): implement local repository and update
 ViewModel & tests

Implemented ProfileRepositoryLocal with basic fake data and CRUD stubs.
Refactored MyProfileViewModel to use the local repository and improved validation/error handling.
Updated unit tests to cover new validation messages and setError behavior.

Subject: [PATCH 239/954] feat: update main page and models to support listings
 and improve tests

- Modify MainPage.kt and MainPageViewModel.kt to integrate listings data with tutor display
- Adjust Listing.kt and Profile.kt models for better compatibility with the updated ViewModel
- Update build.gradle.kts to align SDK and dependencies
- Refactor MainPageTests.kt and ListingTest.kt to match new data structure and UI logic

- Implement load() to fetch skills and listings safely using
  buildTutorCardSafely with try/catch
- Move formatting and rating computations into private helper
  functions (formatPricePerHour, computeAvgStars, ratingCountFor)
- Introduce HomeUiState emitted via StateFlow containing prepared
  TutorCardUi data
- Ensure TutorCardUi includes formatted price labels and clamped
  rating stars (0..5)

+# Credential Manager Integration Summary
+
+## What Changed
+
+I've successfully updated your authentication system to use **Android Credential Manager API** - Google's modern, recommended approach for handling authentication credentials.
+
+## Benefits of Credential Manager
+
+1. **Unified API** - Single interface for passwords, passkeys, and federated sign-in
+2. **Better UX** - Native Android credential picker UI
+3. **Security** - Built-in protection against phishing and credential theft
+4. **Future-proof** - Supports upcoming passkeys and biometric authentication
+5. **Auto-fill Integration** - Seamless integration with Android's password managers
+
+## Implementation Details
+
+### New Dependencies Added
+
+In `libs.versions.toml`:
+```toml
+credentialManager = "1.2.2"
+googleIdCredential = "1.1.1"
+```
+
+In `build.gradle.kts`:
+```kotlin
+implementation(libs.androidx.credentials)
+implementation(libs.androidx.credentials.play.services)
+implementation(libs.googleid)
+```
+
+### Files Modified/Created
+
+1. **CredentialAuthHelper.kt** (NEW)
+   - Manages Credential Manager for password autofill
+   - Provides GoogleSignInClient for Google authentication
+   - Converts credentials to Firebase auth tokens
+
+2. **AuthenticationViewModel.kt** (UPDATED)
+   - Now uses CredentialAuthHelper instead of GoogleSignInHelper
+   - Added `getSavedCredential()` - retrieves saved passwords from Credential Manager
+   - Uses `getGoogleSignInClient()` for Google Sign-In flow
+   - Handles activity results for Google Sign-In
+
+3. **MainActivity.kt** (UPDATED)
+   - Uses `rememberLauncherForActivityResult` for Google Sign-In
+   - Simplified LoginApp setup with activity result handling
+
+4. **GoogleSignInHelper.kt** (REPLACED)
+   - Old file is no longer needed
+   - Functionality merged into CredentialAuthHelper
+
+## How It Works
+
+### Password Authentication with Credential Manager
+
+```kotlin
+// User can retrieve saved credentials
+viewModel.getSavedCredential()  // Auto-fills email/password from saved credentials
+
+// Regular sign-in still works
+viewModel.signIn()  // Signs in with email/password
+```
+
+The Credential Manager will:
+- Show a native Android picker with saved credentials
+- Auto-fill the login form
+- Offer to save new credentials after successful login
+
+### Google Sign-In
+
+The implementation uses a **hybrid approach**:
+- **Credential Manager** for password credentials (modern API)
+- **Google Sign-In SDK** for Google authentication (more reliable and simpler)
+
+The flow:
+1. User clicks "Sign in with Google"
+2. Activity result launcher opens Google Sign-In UI
+3. User selects Google account
+4. ViewModel processes the result and signs into Firebase
+
+## Key Features
+
+✅ **Password Autofill** - Credential Manager provides saved passwords
+✅ **Google Sign-In** - Seamless Google authentication flow
+✅ **Email/Password** - Traditional email/password authentication
+✅ **Password Reset** - Send password reset emails
+✅ **Role Selection** - Choose between Learner and Tutor
+✅ **MVVM Architecture** - Clean separation of concerns
+✅ **Firebase Integration** - Works with Firebase Auth and emulators
+
+## Usage Example
+
+```kotlin
+@Composable
+fun LoginApp() {
+  val viewModel = AuthenticationViewModel(context)
+  
+  // Register Google Sign-In launcher
+  val googleSignInLauncher = rememberLauncherForActivityResult(
+      contract = ActivityResultContracts.StartActivityForResult()
+  ) { result ->
+    viewModel.handleGoogleSignInResult(result)
+  }
+
+  // Optional: Try to load saved credentials on start
+  LaunchedEffect(Unit) {
+    viewModel.getSavedCredential()
+  }
+
+  LoginScreen(
+      viewModel = viewModel,
+      onGoogleSignIn = {
+        val signInIntent = viewModel.getGoogleSignInClient().signInIntent
+        googleSignInLauncher.launch(signInIntent)
+      })
+}
+```
+
+## Testing
+
+The authentication system is ready to test:
+- **Email/Password**: Enter credentials and click Sign In
+- **Google Sign-In**: Click the Google button to launch Google account picker
+- **Password Autofill**: Android will offer to save/retrieve credentials
+- **Firebase Emulator**: Works with your existing emulator setup (10.0.2.2:9099)
+
+## Future Enhancements
+
+The Credential Manager API is ready for:
+- **Passkeys** - Passwordless authentication (coming soon)
+- **Biometric Auth** - Fingerprint/face authentication
+- **Cross-device Credentials** - Sync credentials across devices
+- **Third-party Password Managers** - Integration with 1Password, LastPass, etc.
+
+## Notes
+
+- The old `GoogleSignInHelper.kt` file can be deleted
+- Minor warning about context leak is acceptable for ViewModels with application context
+- The `getSavedCredential()` function is available but not currently used in the UI (you can add a button for it later)

Subject: [PATCH 313/954] feat: Clean up code formatting and improve navigation
 structure. Removed unused imports and adjusted parameter formatting for
 better readability across multiple files. Fixed old navigation tests that are
 now incompatible with the implementation, removed useless ones and added new
 ones.

Subject: [PATCH 345/954] feat(ui): make subjects list horizontally scrollable
 and display correct items

- Updated ExploreSubjects composable to use LazyRow for horizontal scrolling
- Ensured each SubjectCard displays the correct subject and color
- Improved spacing and layout for smoother scrolling experience
- Verified subjects render dynamically from HomeUiState

Subject: [PATCH 356/954] add necessary repositories for sign up and connected
 the logic with sign in and navigation

I added the necessary repositories for the sign up so that it wouldn't use the fake repositories and used firebase instead. Also i edited the tests for these so that the new implementations are tested correctly.

Subject: [PATCH 369/954] feat(ui): make MainSubjects clickable and navigate
 with selected subject

- Updated HomePage to make each MainSubject element clickable
- Implemented navigation logic to pass the selected subject to the next page
- Modified the destination page to dynamically display content based on the received subject
- Updated skill input field to show the selected skill with proper formatting
- Added fallback logic to display example skills when no selection is made
- Improved string handling using buildString and take(3) for safer, cleaner code
- Enhanced overall UX by providing clear visual feedback for selected subjects and skills

Subject: [PATCH 581/954] feat: Add different subscreens in MyProfileScreen

../MyProfileScreen.kt: change the navbar in the screen
	and add the listing tab. Change the box with
	profile informations and add the save button
	which's state depend on the modification of fields.
	Remove the save button form the floating button
	field in the scaffold because rendering was
	attrocious. Implement the page with the ratings.

../MyProfileViewModel.kt: implement the function that loads
	the ratings that the user recieves.

../RatingCard.kt: create a card that displays the
	ratings a user recieves.

- * A fake implementation of [ListingRepository] that provides a predefined set of listings.

- * This mock repository is used for testing and development purposes, simulating a repository with
- * actual proposal and request listings without requiring a real backend.
- *
- * Features:
- * - Contains two initial listings: one Proposal and one Request.
- * - Supports adding, updating, deleting, and deactivating listings.
- * - Supports simple search by skill or location (mock implementation).
- * - Returns copies or filtered lists to avoid external mutation.
- *
- * Typical use cases:
- * - Verifying ViewModel or UseCase logic when listings exist.
- * - Testing UI rendering of proposals and requests.
- * - Simulating user actions such as adding or deactivating listings.

+ * Features:
+ * - Contains two initial listings: one Proposal and one Request.
+ * - Supports adding, updating, deleting, and deactivating listings.
+ * - Supports simple search by skill or location (mock implementation).
+ * - Returns copies or filtered lists to avoid external mutation.

+ * - Testing UI rendering of proposals and requests.

+This file describes how to use fake repositories.
+
+All fake repositories implement a fake interface that implements the real interface of
+the correct repository (e.g interface FakeProfileRepo : ProfileRepository).
+
+This allows us to define helper methods to test what each repository contains and call them
+in the tests.
+(e.g in the fake listing repo: getLastListingCreated to check whether a listing has been added).
+
+There are three types of repositories:
+- ‘error’
+- ‘empty’
+- ‘working’
+
+Error Repository :
+Returns an error for each request.
+This repository is used to test the UI when there is an error with the repositories.
+
+Empty Repository :
+Has no data during initialisation.
+This repository is used to test the UI when there is no data yet in a repository.
+
+Working Repository :
+Has data during initialisation.
