+# Fast Messenger Tech Debt Audit
+
+## Critical
+
+### `core/network/src/main/kotlin/dev/meloda/fast/network/interceptor/Error14HandlingInterceptor.kt`
+- captcha flow is built around `wait/notify`, a raw executor, and shared mutable state.
+- risk: deadlocks, leaked jobs, hard-to-reproduce auth hangs.
+- fix: rewrite as suspend-based flow with timeout and explicit cancellation.
+
+### `core/domain/src/main/kotlin/dev/meloda/fast/domain/LongPollEventParser.kt`
+- file mixes parsing, dispatching, IO loading, and concurrency orchestration.
+- risk: regressions when VK event format changes.
+- fix: split by event family and add parser tests.
+
+### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/MessagesHistoryViewModelImpl.kt`
+- view model is doing too much: loaders, navigation, selection, long poll hooks, read peers, dialog flow.
+- risk: brittle state transitions and untestable branching.
+- fix: extract coordinators/handlers per concern.
+
+### `app/src/main/kotlin/dev/meloda/fast/MainViewModel.kt`
+- root bootstrap handles auth, locale, long poll, permissions, profile, and start destination in one class.
+- risk: startup bugs and hidden coupling between flows.
+- fix: move startup/permission orchestration into dedicated controllers.
+
+### `app/src/main/kotlin/dev/meloda/fast/presentation/RootScreen.kt`
+- root composable owns too many top-level flows and dialogs.
+- risk: UI orchestration drift and hard-to-read navigation logic.
+- fix: split dialogs, bootstrap, and navigation concern into smaller composables.
+
+## High
+
+### `core/domain/src/main/kotlin/dev/meloda/fast/domain/LongPollEventParser.kt`
+- uses many `Log.d` calls and large `when` branches.
+- fix: reduce logging noise and add structured tracing only where needed.
+
+### `core/network/src/main/kotlin/dev/meloda/fast/network/ResponseConverterFactory.kt`
+- double-parsing response bodies and only logging malformed payloads.
+- risk: opaque failures and harder debugging.
+- fix: normalize error conversion and surface typed failures.
+
+### `feature/profile/src/main/kotlin/dev/meloda/fast/profile/ProfileViewModel.kt`
+- `loadAccountInfo()` has an empty error branch.
+- risk: profile can fail silently.
+- fix: set `baseError` and show fallback UI.
+
+### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/presentation/attachments/Attachments.kt`
+- attachment preview logic still sits in UI layer and mixes fallback behavior.
+- risk: silent drops of unsupported attachments.
+- fix: move preview mapping to domain/ui-model layer.
+
+### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/presentation/Link.kt`
+- title handling is nullable and duplicated with preview logic.
+- fix: create a small UI model for link rendering.
+
+### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/presentation/File.kt`
+- preview extraction is inline and branches on raw model internals.
+- fix: extract to mapper/UI model.
+
+### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/presentation/MessagesList.kt`
+- message-item interaction is dense and repeated.
+- fix: normalize scroll/reply handlers and reduce nested callbacks.
+
+## Medium
+
+### `core/data/src/main/kotlin/dev/meloda/fast/data/VkUsersMap.kt`
+- lookup helpers were using unsafe assumptions on external data.
+- status: already improved, but should stay covered by tests.
+
+### `core/data/src/main/kotlin/dev/meloda/fast/data/VkGroupsMap.kt`
+- same risk profile as users map.
+- status: already improved, still needs tests.
+
+### `core/domain/src/main/kotlin/dev/meloda/fast/domain/OAuthUseCaseImpl.kt`
+- auth success mapping used forced unwraps on server data.
+- status: already improved, but auth contract should be validated.
+
+### `app/src/main/kotlin/dev/meloda/fast/presentation/MainActivity.kt`
+- service lifecycle now respects config changes, but app exit semantics should be documented.
+- fix: keep explicit separation of app-close vs config-change behavior.
+
+### `build-logic/convention/src/main/kotlin/dev/meloda/fast/KotlinAndroid.kt`
+- build-tools are pinned to the local environment.
+- risk: portable builds may drift between machines.
+- fix: prefer SDK-managed consistency or document required SDK version.
+
+### `app/src/main/kotlin/dev/meloda/fast/presentation/RootErrorDialog.kt`
+- currently hardcodes English strings for some errors.
+- fix: localize all texts through resources.
+
+### `app/src/main/kotlin/dev/meloda/fast/presentation/RootScreen.kt`
+- root-level error dialog is better, but some orchestration still remains in the root composable.
+- fix: split into smaller root flows over time.
+
+## Low
+
+### `core/ui/src/main/kotlin/dev/meloda/fast/ui/components/AnimatedDots.kt`
+- marked TODO rewrite.
+- fix when touching related loading UI.
+
+### `core/ui/src/main/kotlin/dev/meloda/fast/ui/theme/AppTheme.kt`
+- color picker TODO suggests unfinished theme customization.
+
+### `core/model/src/main/kotlin/dev/meloda/fast/model/api/data/LongPollUpdates.kt`
+- `List<List<Any>>` is a weakly typed API boundary.
+- fix: introduce explicit event DTOs.
+
+### `core/model/src/main/kotlin/dev/meloda/fast/model/api/domain/VkMessage.kt`
+- attachment persistence is still a TODO area.
+
+### `core/model/src/main/kotlin/dev/meloda/fast/model/database/VkMessageEntity.kt`
+- attachment storage/restoration is unresolved.
+
+### `core/common/src/main/kotlin/dev/meloda/fast/common/model/LongPollState.kt`
+- Android 15 support TODO.
+
+### `feature/messageshistory/src/main/kotlin/dev/meloda/fast/messageshistory/MessagesHistoryViewModelImpl.kt`
+- large commented-out legacy block should be removed once upload flow is reimplemented.
+
+### `feature/auth/src/main/kotlin/dev/meloda/fast/auth/login/LoginViewModel.kt`
+- debug/auth token acquisition TODO indicates unfinished auth path.
+
+## What To Do First
+1. Rewrite captcha interceptor.
+2. Split `LongPollEventParser`.
+3. Extract `MessagesHistoryViewModelImpl` orchestration.
+4. Localize `RootErrorDialog` strings.
+5. Add tests for auth, long poll parsing, and attachment mapping.
+
+## Note
+- Current code is already better on crash-prone nullable handling and service lifecycle.
+- Remaining work is mostly structural and testability-focused.

melod1n	ce375c902c	Refactor: Improve reply component layout and styling This commit refactors the `Reply` composable for better layout consistency and simplifies its implementation. The `Reply` component no longer uses a fixed height, allowing it to dynamically resize based on its content. The layout has been updated from a `Box` to a `Row` to properly align the side indicator bar with the height of the text content. Padding and corner rounding logic has been simplified and centralized within the `Reply` composable itself, removing redundant parameters from the `MessageBubble`. Key changes: - `Reply` composable now uses `Row` for its root layout instead of `Box`. - Removed the fixed `48.dp` height to allow dynamic content sizing. - The side indicator bar's height now matches the text content's height. - Simplified padding and shape logic in `MessageBubble` by removing conditional parameters passed to `Reply`. - Adjusted padding inside `MessageBubble` to accommodate the new `Reply` layout.	2026-02-06 22:58:03 +03:00

Key changes: - Replaced `ic_star_round_24` with `ic_star_fill_round_24` for "important" messages in `DateStatus` and the "Mark as Important" action. - Replaced `ic_edit_round_24` with `ic_edit_fill_round_24` for "edited" messages in `DateStatus`. - Added the new `ic_edit_fill_round_24` drawable resource. - In `MessageBubble`, the `derivedStateOf` for `shouldFill` is now wrapped in a `remember` block to prevent unnecessary recompositions.	2026-01-24 21:58:11 +03:00

melod1n	2a238fa1bf	Refactor: Upgrade Gradle and streamline build logic This commit upgrades the project's build system and refactors the build logic for better maintainability and alignment with modern practices. The Gradle version has been updated from 8.14.2 to 9.3.0, and the Android Gradle Plugin (AGP) has been upgraded to version 9.0.0. This required migrating the build logic to use the new `com.android.build.api.dsl` interfaces instead of the deprecated `com.android.build.gradle` ones. Key changes: - Upgraded Gradle to `9.3.0`. - Upgraded Android Gradle Plugin to `9.0.0`. - Updated various dependencies including Kotlin, Compose BOM, Chucker, and serialization. - Removed the explicit `kotlin-android` plugin application, as it's now handled by AGP. - Migrated build convention plugins to use the new AGP DSL APIs. - Commented out the custom APK naming logic in `app/build.gradle.kts`. - Added new `gradle.properties` flags for build configuration. - Corrected the namespace in `core/model` from `datastore` to `model`.	2026-01-24 14:58:04 +03:00

melod1n	7ab333280c	Refactor: Clean up unused code and improve error handling This commit performs a general cleanup of the codebase by removing unused dependencies, comments, and functions. It also improves error handling in the build logic. Key changes: - Removed a TODO and an inappropriate function `dickPizda` from `Extensions.kt`. - Removed stale TODO comments from `core/data/build.gradle.kts` and `core/domain/build.gradle.kts`. - Replaced a `TODO` call with a proper `IllegalArgumentException` in `KotlinAndroid.kt` for better error reporting when encountering unsupported project extensions.	2025-12-27 20:56:02 +03:00

melod1n	7b6571f208	Feat: Add animation to reply summary visibility This commit wraps the reply summary `Text` composable within an `AnimatedVisibility` component.

melod1n	389d3f9e52	Style: Update message bubble colors Updates the container colors for incoming and outgoing message bubbles to align with Material 3 design tokens. - The outgoing message bubble container color is changed from `surfaceColorAtElevation(2.dp)` to `surfaceContainer`. - The reply container color within an outgoing message is changed from `primaryContainer` to `surfaceContainerHighest`. Additionally, the `@Preview` for `MessageBubble` is updated to display both an incoming and an outgoing message for better design validation.	2025-12-15 23:08:42 +03:00
melod1n	69a50f8fcd	Refactor: Encapsulate MessageBubble colors This commit refactors the `MessageBubble` composable by extracting the color logic into a private `messageBubbleColors` function. This function returns an immutable `MessageBubbleColors` data class, which holds the container, content, and reply container colors. This change cleans up the main composable, improves readability, and centralizes color definitions for both incoming and outgoing messages. Additionally, the background color logic for attachments has been simplified to make it transparent for media types like stickers and videos.	2025-12-15 23:01:38 +03:00
melod1n	8839015249	Fix: Ensure sender's name truncates correctly in incoming messages This commit resolves an issue where the sender's name in incoming message bubbles would not truncate properly, potentially breaking the layout. The fix ensures the name text correctly adapts to the width of the message bubble. Additionally, this change introduces `ImmutableList` for message attachments to improve performance and refactors where the conversion to `ImmutableList` happens, moving it into the `MessageMapper`. Key changes: - The `MessageBubble` now reports its width, allowing the sender's name `Text` to be constrained correctly. - Sender's name now uses `labelMedium` typography. - Enabled showing the sender's name by default in `MessagesHistoryViewModelImpl`. - Changed `UiItem.Message.attachments` from `List` to `ImmutableList` for better Compose performance. - Moved the `toImmutableList()` conversion for attachments into the `MessageMapper`.	2025-12-15 22:58:50 +03:00
melod1n	478639e427	Refactor: Extract RootScreen from MainActivity and fix reply message user This commit refactors the UI composition logic by extracting it from `MainActivity` into a new, dedicated `RootScreen` composable. This improves the separation of concerns and simplifies `MainActivity`. Additionally, a bug has been fixed where a replied-to message would incorrectly display the author of the parent message instead of its own author. Key changes: - Moved theme setup, permission handling, Long-Poll/Online service management, and navigation graph hosting into the new `RootScreen.kt`. - `MainActivity` is now significantly simplified, delegating its UI composition to `RootScreen`. - Corrected the user and group assignment for `replyMessage` in `MessagesRepositoryImpl` to ensure the correct author is displayed. - Introduced `OnlineFriendsViewModel` to the `FriendsRoute` to separate the logic for online friends. - Replaced `List` with a custom `ImmutableList` for `photoViewerInfo` state to improve Compose stability.	2025-12-15 22:24:17 +03:00
