Subject: [PATCH 001/132] refactor: Standardize import statements and improve
 code readability across components

- Updated import statements to use consistent single quotes.
- Refactored various components to enhance readability and maintainability.
- Adjusted folder and file handling logic in the sidebar and file manager components.
- Introduced a new tabbed interface for the files page to separate files and knowledge bases, improving user experience.

Subject: [PATCH 003/132] feat: Introduce new Files and Knowledge Bases page
 with tabbed interface

- Added a new FilesPage component to manage file uploads and organization.
- Implemented a tabbed interface to separate Files and Knowledge Bases for improved user experience.
- Created FilesTab and KnowledgeBasesTab components for handling respective functionalities.
- Refactored routing to accommodate the new structure and updated import statements for consistency.
- Removed the old filesPage component to streamline the codebase.

Subject: [PATCH 029/132] feat: refactor file management and knowledge base
 components

- Replaced the existing assetsPage with a new filesPage to better organize file management functionalities.
- Introduced KnowledgePage to handle knowledge base operations, integrating KnowledgeBasesTab for displaying and managing knowledge bases.
- Added various components for file and knowledge base management, including CreateKnowledgeBaseButton, KnowledgeBaseEmptyState, and drag-and-drop functionality.
- Updated routing and imports to reflect the new structure and ensure consistency across the application.
- Enhanced user experience with improved UI elements and state management for file selection and operations.

Subject: [PATCH 030/132] feat: implement delete confirmation modal for
 knowledge base deletion

- Added a DeleteConfirmationModal component to confirm deletion actions.
- Integrated the modal into the KnowledgeBasesTab for handling knowledge base deletions.
- Updated column definitions to include a delete button for each knowledge base.
- Enhanced user experience by ensuring deletion actions require confirmation.
- Adjusted styles for the knowledge base table to improve checkbox visibility.

Subject: [PATCH 031/132] feat: enhance knowledge base metadata with embedding
 model detection

- Added `embedding_model` field to `KnowledgeBaseInfo` for improved metadata tracking.
- Implemented `detect_embedding_model` function to extract embedding model information from configuration files.
- Updated `get_kb_metadata` to prioritize metadata extraction from `embedding_metadata.json`, falling back to detection if necessary.
- Modified `KBIngestionComponent` to save embedding model metadata during ingestion.
- Adjusted frontend components to display embedding model information in knowledge base queries and tables.

Subject: [PATCH 035/132] feat: implement bulk and single deletion for
 knowledge bases

- Added `BulkDeleteRequest` model to handle bulk deletion requests.
- Implemented `delete_knowledge_base` endpoint for single knowledge base deletion.
- Created `delete_knowledge_bases_bulk` endpoint for deleting multiple knowledge bases at once.
- Introduced `useDeleteKnowledgeBase` and `useDeleteKnowledgeBases` hooks for frontend integration.
- Updated `KnowledgeBaseSelectionOverlay` and `KnowledgeBasesTab` components to utilize new deletion functionality with user feedback on success and error handling.

Subject: [PATCH 037/132] feat: add KnowledgeBaseDrawer component for enhanced
 knowledge base details

- Introduced `KnowledgeBaseDrawer` component to display detailed information about selected knowledge bases.
- Integrated mock data for source files and linked flows, with a layout for displaying descriptions and embedding models.
- Updated `KnowledgeBasesTab` to handle row clicks and open the drawer with relevant knowledge base data.
- Enhanced `KnowledgePage` to manage drawer state and selected knowledge base, improving user interaction and experience.

Subject: [PATCH 042/132] feat: update mock data and enhance drawer
 functionality in KnowledgeBase components

- Replaced mock data in `KnowledgeBaseDrawer` with more descriptive placeholders.
- Added a reference to the drawer in `KnowledgePage` for improved click handling.
- Implemented logic to close the drawer when clicking outside, except for table row clicks.
- Enhanced row click handling to toggle drawer state based on current visibility.

Subject: [PATCH 045/132] refactor: improve knowledge base deletion and UI
 components

- Updated `useDeleteKnowledgeBase` and `useDeleteKnowledgeBases` to enhance parameter naming for clarity.
- Removed the `CreateKnowledgeBaseButton` component and its references to streamline the UI.
- Simplified the `KnowledgeBaseDrawer` and `KnowledgeBasesTab` components by removing mock data and improving state management.
- Enhanced the `KnowledgeBaseSelectionOverlay` to better handle bulk deletions and selection states.
- Refactored various components for consistent styling and improved readability.

Subject: [PATCH 047/132] feat: Add encryption for API keys in KB ingest and
 retrieval (#9129)

Add encryption for API keys in KB ingest and retrieval

Introduces secure storage of embedding model API keys by encrypting them during knowledge base ingestion and decrypting them during retrieval. Refactors metadata handling to include encrypted API keys, updates retrieval to support decryption and dynamic embedder construction, and improves logging for key operations. Removes legacy embedding client code in retrieval in favor of a provider-based approach.

Subject: [PATCH 054/132] feat: enhance table component with editable Vectorize
 column functionality

- Implemented logic to determine editability of the Vectorize column based on other row values.
- Added checks to refresh grid cells upon changes to the Vectorize column.
- Updated TableAutoCellRender to conditionally disable editing based on Vectorize column state.

Subject: [PATCH 086/132] Update Knowledge Bases configuration and enhance UI
 components

- Updated the code hash in the Knowledge Bases JSON configuration.
- Modified the KnowledgeBaseEmptyState component to change the button icon and text from "Try Knowledge Base Template" to "Create Knowledge".
- Cleared the options for the knowledge base selection dropdowns to ensure they reflect the current state of available knowledge bases.

Subject: [PATCH 088/132] Implement feature flag for Knowledge Bases
 functionality

- Added FEATURE_FLAGS.knowledge_bases to control the visibility of knowledge base components in the API and UI.
- Updated the router to conditionally include the knowledge bases router based on the feature flag.
- Modified KBIngestionComponent and KBRetrievalComponent to hide if the knowledge bases feature is disabled.
- Enhanced the initial setup to skip loading knowledge base starter projects when the feature is disabled.
- Updated frontend routes and sidebar components to conditionally render knowledge base options based on the feature flag.
- Adjusted API queries to return an empty array if the knowledge bases feature is disabled.

Subject: [PATCH 091/132] Refactor Knowledge Bases feature flag implementation

- Removed the FEATURE_FLAGS.knowledge_bases flag from backend components and frontend routes.
- Updated the API and UI to always include knowledge base components, simplifying the codebase.
- Adjusted the frontend feature flags to set ENABLE_KNOWLEDGE_BASES to false, ensuring knowledge base features are not displayed.
- Cleaned up related components and routes to reflect the removal of the feature flag, enhancing maintainability.

Subject: [PATCH 104/132] feat: enhance Jest configuration and add new tests
 for Knowledge Base components

- Updated jest.config.js to include a new setup file and refined test matching patterns.
- Introduced jest.setup.js for mocking globals and Vite-specific syntax.
- Added tests for KnowledgeBaseDrawer, KnowledgeBaseEmptyState, KnowledgeBaseSelectionOverlay, KnowledgeBasesTab, and KnowledgePage components.
- Created utility functions for testing and mock data for knowledge bases.
- Implemented tests for utility functions related to knowledge base formatting.
