Implement automatic discarding of conversations shorter than 30 seconds with ability to restore them. This helps reduce clutter from accidental or test recordings while preserving user control.

Backend changes:

  • Add duration, discarded_reason, discarded_at, restored_at fields to Conversation model
  • Add 'discarded' status to ConversationStatus enum
  • Implement auto-discard logic for conversations < 30 seconds
  • Add /discard and /restore API endpoints
  • Add Firestore composite index for efficient querying
  • Add test endpoints for validation

Frontend changes:

  • Update conversation data model with discard fields
  • Add discardConversation() and restoreConversation() API functions
  • Implement restoreConversationLocally() in provider
  • Add smart swipe actions (green restore for discarded, red delete for active)
  • Add "Show Discarded" toggle switch on conversations page
  • Update conversation cards to show "Auto-discarded" tag

Tested:

Backend API endpoints - Fully tested with curl commands:
-Auto-discard for < 30s conversations: WORKING
-Restore endpoint: WORKING
-Statistics tracking: WORKING
-Test endpoints: ALL WORKING
Code syntax and structure - All verified
-Frontend code follows existing patterns
-Backend code integrates correctly
-No syntax errors
Edge cases handled in code
-Null checks for optional fields
-Status validation
-Proper error handling in API calls

Code Review

This pull request introduces a feature to automatically discard short conversations and allow users to restore them. The changes span both the backend and frontend, adding new data model fields, API endpoints, and UI components to support this functionality. My review has identified a few critical issues in the backend implementation that need to be addressed. These include the presence of unauthenticated test endpoints that can modify data, a highly inefficient implementation for calculating statistics which could lead to performance degradation, and the introduction of duplicate, conflicting router files for the new feature. On the frontend, I've noted a minor code quality issue regarding redundant state mutation. Addressing these points will significantly improve the security, performance, and maintainability of the new feature.

The get_conversation_statistics endpoint fetches up to 10,000 conversation documents for a user and then performs calculations in memory. This is highly inefficient and can lead to significant performance issues, high resource consumption, and slow response times for users with many conversations. It could even be a potential denial-of-service vector.

A more scalable approach should be considered. For Firestore, this typically involves maintaining a separate statistics document for each user that is updated incrementally using Cloud Functions (triggers) whenever a conversation's status or duration changes. This avoids expensive full collection scans on every request.

The new test endpoints (/v1/test/*) do not have authentication, and some of them perform write operations to the database (e.g., test_create_mock_conversation, test_discard_conversation, test_restore_conversation). Exposing unauthenticated endpoints that can modify data is a significant security vulnerability, especially if this code is deployed to a production environment. These endpoints should either be removed before merging, protected with authentication and authorization, or conditionally registered only in non-production environments.

This new file conversations_discard.py seems to introduce a new set of endpoints and logic for handling conversation discarding, which significantly overlaps with the new endpoints added in backend/routers/conversations.py. There are also two different helper modules (utils/conversation_discard.py and utils/conversations/conversation_helper.py) supporting these different router files. This creates ambiguity, code duplication, and potential conflicts. It's unclear which implementation is the intended one. Please consolidate these into a single, consistent implementation to avoid confusion and maintainability issues. If conversations_discard.py is the intended refactoring, the changes in conversations.py should be removed.

In restoreConversationLocally, the conversation object is mutated directly before being replaced by restoredConversation from the API response. These mutations are redundant and can be misleading. The restoredConversation object should be treated as the single source of truth for the updated state. Modifying the old object locally can lead to confusion and potential bugs if the replacement logic changes in the future.
