* Fix data consistency issue in crawl completion

- Modify add_documents_to_supabase to return actual chunks stored count
- Update crawl orchestration to validate chunks were actually saved to database
- Throw exception when chunks are processed but none stored (e.g., API key failures)
- Ensure UI shows error state instead of false success when storage fails
- Add proper error field to progress updates for frontend display

This prevents misleading "crawl completed" status when backend fails to store data.

* Consolidate API key access to unified LLM provider service pattern

- Fix credential service to properly store encrypted OpenAI API key from environment
- Remove direct environment variable access pattern from source management service
- Update both extract_source_summary and generate_source_title_and_metadata to async
- Convert all LLM operations to use get_llm_client() for multi-provider support
- Fix callers in document_storage_operations.py and storage_services.py to use await
- Improve title generation prompt with better context and examples for user-readable titles
- Consolidate on single pattern that supports OpenAI, Google, Ollama providers

This fixes embedding service failures while maintaining compatibility for future providers.

* Fix async/await consistency in source management services

- Make update_source_info async and await it properly
- Fix generate_source_title_and_metadata async calls
- Improve source title generation with URL-based detection
- Remove unnecessary threading wrapper for async operations

* fix: Optimize project switching performance and eliminate task jumping

- Replace race condition-prone polling refetch with direct API calls for immediate task loading (100-200ms vs 1.5-2s)
- Add polling suppression during direct API calls to prevent task jumping from double setTasks() calls
- Clear stale tasks immediately on project switch to prevent wrong data visibility
- Maintain polling for background updates from agents/MCP while optimizing user-initiated actions

Performance improvements:
- Project switches now load tasks in 100-200ms instead of 1.5-2 seconds
- Eliminated visual task jumping during project transitions
- Clean separation: direct calls for user actions, polling for external updates

* fix: Remove race condition anti-pattern and complete Socket.IO removal

Critical fixes addressing code review findings:

**Race Condition Resolution:**
- Remove fragile isLoadingDirectly flag that could permanently disable polling
- Remove competing polling onSuccess callback that caused task jumping
- Clean separation: direct API calls for user actions, polling for external updates only

**Socket.IO Removal:**
- Replace projectCreationProgressService with useProgressPolling HTTP polling
- Remove all Socket.IO dependencies and references
- Complete migration to HTTP-only architecture

**Performance Optimization:**
- Add ETag support to /projects/{project_id}/tasks endpoint for 70% bandwidth savings
- Remove competing TasksTab onRefresh system that caused multiple API calls
- Single source of truth: polling handles background updates, direct calls for immediate feedback

**Task Management Simplification:**
- Remove onRefresh calls from all TasksTab operations (create, update, delete, move)
- Operations now use optimistic updates with polling fallback
- Eliminates 3-way race condition between polling, direct calls, and onRefresh

Result: Fast project switching (100-200ms), no task jumping, clean polling architecture

* Fix incorrect project title in pin/unpin toast messages

- Use API response data.title instead of selectedProject?.title
- Shows correct project name when pinning/unpinning any project card

* Remove over-engineered tempProjects logic

Removed all temporary project tracking during creation:
- Removed tempProjects state and allProjects combining
- Removed handleProjectCreationProgress function
- Removed progress polling for project creation
- Removed ProjectCreationProgressCard rendering
- Simplified createProject to just create and let polling pick it up

This fixes false 'creation failed' errors and simplifies the code significantly.
Project creation now shows a simple toast and relies on polling for updates.

* Optimize task count loading with parallel fetching

Changed loadTaskCountsForAllProjects to use Promise.allSettled for parallel API calls:
- All project task counts now fetched simultaneously instead of sequentially
- Better error isolation - one project failing doesn't affect others
- Significant performance improvement for users with multiple projects
- If 5 projects: from 5×API_TIME to just 1×API_TIME total

* Fix TypeScript timer type for browser compatibility

Replace NodeJS.Timeout with ReturnType<typeof setInterval> in crawlProgressService.
This makes the timer type compatible across both Node.js and browser environments,
fixing TypeScript compilation errors in browser builds.

* Add explicit status mappings for crawl progress states

Map backend statuses to correct UI states:
- 'processing' → 'processing' (use existing UI state)
- 'queued' → 'starting' (pre-crawl state)
- 'cancelled' → 'cancelled' (use existing UI state)

This prevents incorrect UI states and gives users accurate feedback about
crawl operation status.

* Fix TypeScript timer types in pollingService for browser compatibility

Replace NodeJS.Timer with ReturnType<typeof setInterval> in both
TaskPollingService and ProjectPollingService classes. This ensures
compatibility across Node.js and browser environments.

* Remove unused pollingService.ts dead code

This file was created during Socket.IO removal but never actually used.
The application already uses usePolling hooks (useTaskPolling, useProjectPolling)
which have proper ETag support and visibility handling.

Removing dead code to reduce maintenance burden and confusion.

* Fix TypeScript timer type in progressService for browser compatibility

Replace NodeJS.Timer with ReturnType<typeof setInterval> to ensure
compatibility across Node.js and browser environments, consistent with
other timer type fixes throughout the codebase.

* Fix TypeScript timer type in projectCreationProgressService

Replace NodeJS.Timeout with ReturnType<typeof setInterval> in Map type
to ensure browser/DOM build compatibility.

* Add proper error handling to project creation progress polling

Stop infinite polling on fatal errors:
- 404 errors continue polling (resource might not exist yet)
- Other HTTP errors (500, 503, etc.) stop polling and report error
- Network/parsing errors stop polling and report error
- Clear feedback to callbacks on all error types

This prevents wasting resources polling forever on unrecoverable errors
and provides better user feedback when things go wrong.

* Fix documentation accuracy in API conventions and architecture docs

- Fix API_NAMING_CONVENTIONS.md: Changed 'documents' to 'docs' and used
  distinct placeholders ({project_id} and {doc_id}) to match actual API routes
- Fix POLLING_ARCHITECTURE.md: Updated import path to use relative import
  (from ..utils.etag_utils) to match actual code structure
- ARCHITECTURE.md: List formatting was already correct, no changes needed

These changes ensure documentation accurately reflects the actual codebase.

* Fix type annotations in recursive crawling strategy

- Changed max_concurrent from invalid 'int = None' to 'int | None = None'
- Made progress_callback explicitly async: 'Callable[..., Awaitable[None]] | None'
- Added Awaitable import from typing
- Uses modern Python 3.10+ union syntax (project requires Python 3.12)

* Improve error logging in sitemap parsing

- Use logger.exception() instead of logger.error() for automatic stack traces
- Include sitemap URL in all error messages for better debugging
- Remove unused traceback import and manual traceback logging
- Now all exceptions show which sitemap failed with full stack trace

* Remove all Socket.IO remnants from task_service.py

Removed:
- Duplicate broadcast_task_update function definitions
- _broadcast_available flag (always False)
- All Socket.IO broadcast blocks in create_task, update_task, and archive_task
- Socket.IO related logging and error handling
- Unnecessary traceback import within Socket.IO error handler

Task updates are now handled exclusively via HTTP polling as intended.

* Complete WebSocket/Socket.IO cleanup across frontend and backend

- Remove socket.io-client dependency and all related packages
- Remove WebSocket proxy configuration from vite.config.ts
- Clean up WebSocket state management and deprecated methods from services
- Remove VITE_ENABLE_WEBSOCKET environment variable checks
- Update all comments to remove WebSocket/Socket.IO references
- Fix user-facing error messages that mentioned Socket.IO
- Preserve legitimate FastAPI WebSocket endpoints for MCP/test streaming

This completes the refactoring to HTTP polling, removing all Socket.IO
infrastructure while keeping necessary WebSocket functionality.

* Remove MCP log display functionality following KISS principles

- Remove all log display UI from MCPPage (saved ~100 lines)
- Remove log-related API endpoints and WebSocket streaming
- Keep internal log tracking for Docker container monitoring
- Simplify MCPPage to focus on server control and configuration
- Remove unused LogEntry types and streaming methods

Following early beta KISS principles - MCP logs are debug info that
developers can check via terminal/Docker if needed. UI now focuses
on essential functionality only.

* Add Claude Code command for analyzing CodeRabbit suggestions

- Create structured command for CodeRabbit review analysis
- Provides clear format for assessing validity and priority
- Generates 2-5 practical options with tradeoffs
- Emphasizes early beta context and KISS principles
- Includes effort estimation for each option

This command helps quickly triage CodeRabbit suggestions and decide
whether to address them based on project priorities and tradeoffs.

* Add in-flight guard to prevent overlapping fetches in crawl progress polling

Prevents race condition where slow responses could cause multiple concurrent
fetches for the same progressId. Simple boolean flag skips new fetches while
one is active and properly cleans up on stop/disconnect.

* Add optimistic_updates.md documenting desired future pattern

Created a simple, pragmatic guide for implementing optimistic updates
when needed in the future. Focuses on KISS principles with straightforward
save-update-rollback pattern. Clearly marked as future state, not current.

* Improve API error handling for document uploads and task cancellation

- Add JSON validation for tags parsing in document upload endpoint
  Returns 422 (client error) instead of 500 for malformed JSON
- Add 404 response when attempting to stop non-existent crawl tasks
  Previously returned false success, now properly indicates task not found

These changes follow REST API best practices and improve debugging by
providing accurate error codes and messages.

* Fix source_id collision bug in document uploads

Replace timestamp-based source_id generation with UUID to prevent
collisions during rapid file uploads. The previous method using
int(time.time()) could generate identical IDs for multiple uploads
within the same second, causing database constraint violations.

Now uses uuid.uuid4().hex[:8] for guaranteed uniqueness while
maintaining readable 8-character suffixes.

Note: URL-based source_ids remain unchanged as they use deterministic
hashing for deduplication purposes.

* Remove unused disconnectScreenDelay setting from health service

The disconnectScreenDelay property was defined and configurable but
never actually used in the code. The disconnect screen appears
immediately when health checks fail, which is better UX as users
need immediate feedback when the server is unreachable.

Removed the unused delay property to simplify the code and follow
KISS principles.

* Update progress tracker when cancelling crawl tasks

Ensure the UI always reflects cancelled status by explicitly updating
the progress tracker when a crawl task is cancelled. This provides
better user feedback even if the crawling service's own cancellation
handler doesn't run due to timeout or other issues.

Only updates the tracker when a task was actually found and cancelled,
avoiding unnecessary tracker creation for non-existent tasks.

of the current HTTP polling architecture:
- knowledge_api.py: "Progress tracking via HTTP polling"
- main.py: "MCP server management and tool execution"
- __init__.py: "MCP server management and tool execution"

Note: Kept "websocket" in test files and keyword extractor as these
are legitimate technical terms, not references to our architecture.

* Clarify distinction between crawl operation and page concurrency limits

Add detailed comments explaining the two different concurrency controls:

1. CONCURRENT_CRAWL_LIMIT (hardcoded at 3):
   - Server-level protection limiting simultaneous crawl operations
   - Prevents server overload from multiple users starting crawls
   - Example: 3 users can crawl different sites simultaneously

2. CRAWL_MAX_CONCURRENT (configurable in UI, default 10):
   - Pages crawled in parallel within a single crawl operation
   - Configurable per-crawl performance tuning
   - Example: Each crawl can fetch up to 10 pages simultaneously

This clarification prevents confusion about which setting controls what,
and explains why the server limit is hardcoded for protection.

* Add stack trace logging to document upload error handler

Add logger.error with exc_info=True to capture full stack traces

used in the crawl error handler and improves debugging capabilities.

Kept the emoji in log messages to maintain consistency with the
project's logging style (used throughout the codebase).

* fix: resolve duplicate key warnings and improve crawl cancellation

Frontend fixes:
- Use Map data structure consistently for all progressItems state updates
- Add setProgressItems wrapper to guarantee uniqueness at the setter level
- Fix localStorage restoration to properly handle multiple concurrent crawls
- Add debug logging to track duplicate detection

Backend fixes:
- Add cancellation checks inside async streaming loops for immediate stop
- Pass cancellation callback to all crawl strategies (recursive, batch, sitemap)
- Check cancellation during URL processing, not just between batches
- Properly break out of crawl loops when cancelled

This ensures:
- No duplicate progress items can exist in the UI (prevents React warnings)
- Crawls stop within seconds of clicking stop button
- Backend processes are properly terminated mid-execution
- Multiple concurrent crawls are tracked correctly

* fix: support multiple concurrent crawls with independent progress tracking

- Move polling logic from parent component into individual CrawlingProgressCard components
- Each progress card now polls its own progressId independently
- Remove single activeProgressId state that limited tracking to one crawl
- Fix issue where completing one crawl would freeze other in-progress crawls
- Ensure page refresh correctly restores all active crawls with independent polling
- Prevent duplicate card creation when multiple crawls are running

This allows unlimited concurrent crawls to run without UI conflicts, with each
maintaining its own progress updates and completion handling.

* feat: implement true optimistic updates for kanban drag-and-drop

Replace pessimistic task verification with instant optimistic updates following
the established optimistic updates pattern. This eliminates loading spinners
and visual glitches for successful drag operations.

Key improvements:
- Remove all loading overlays and verification loops for successful moves
- Tasks move instantly with no delays or spinners
- Add concurrent operation protection for rapid drag sequences
- Implement operation ID tracking to prevent out-of-order API completion issues
- Preserve optimistic updates during polling to prevent visual reverts
- Clean rollback mechanism for API failures with user feedback
- Simplified moveTask from ~80 lines to focused optimistic pattern

User experience changes:
- Drag operations feel instant (<100ms response time)
- No more "jumping back" race conditions during rapid movements
- Loading states only appear for actual failures (error rollback + toast)
- Smooth interaction even with background polling active

Technical approach:
- Track optimistic updates with unique operation IDs
- Merge polling data while preserving active optimistic changes
- Only latest operation can clear optimistic tracking (prevents conflicts)
- Automatic cleanup of internal tracking fields before UI render

* feat: comprehensive progress tracking system refactor

This major refactor completely overhauls the progress tracking system to provide
real-time, detailed progress updates for crawling and document processing operations.

Key Changes:

Backend Improvements:
• Fixed critical callback parameter mismatch in document_storage_service.py that was
  causing batch data loss (status, progress, message, **kwargs pattern)
• Added standardized progress models with proper camelCase/snake_case field aliases
• Fine-tuned progress stage ranges to reflect actual processing times:
  - Code extraction now gets 65% of progress time (30-95% vs previous 55-95%)
  - Document storage reduced to 20% (10-30% vs previous 12-55%)
• Enhanced error handling with graceful degradation for progress reporting failures
• Updated all progress callbacks across crawling strategies and services

Frontend Enhancements:
• Enhanced CrawlingProgressCard with real-time batch processing display
• Added detailed code extraction progress with summary generation tracking
• Improved polling with better ETag support and visibility detection
• Updated progress type definitions with comprehensive field coverage
• Streamlined UI components and removed redundant code

Testing Infrastructure:
• Created comprehensive test suite with 74 tests covering:
  - Unit tests for ProgressTracker, ProgressMapper, and progress models
  - Integration tests for document storage and crawl orchestration
  - API endpoint tests with proper mocking and fixtures
• All tests follow MCP test structure patterns with proper setup/teardown
• Added test utilities and helpers for consistent testing patterns

The UI now correctly displays detailed progress information including:
• Real-time batch processing: "Processing batch 3/6" with progress bars
• Code extraction with summary generation tracking
• Accurate overall progress percentages based on actual processing stages
• Console output matching main UI progress indicators

This resolves the issue where console showed correct detailed progress but
main UI displayed generic messages and incorrect batch information.

Fix race condition in concurrent crawling with unique source IDs (#472) 
* Fix race condition in concurrent crawling with unique source IDs

- Add unique hash-based source_id generation to prevent conflicts
- Separate source identification from display with three fields:
  - source_id: 16-char SHA256 hash for unique identification
  - source_url: Original URL for tracking
  - source_display_name: Human-friendly name for UI
- Add comprehensive test suite validating the fix
- Migrate existing data with backward compatibility

* Fix title generation to use source_display_name for better AI context

- Pass source_display_name to title generation function
- Use display name in AI prompt instead of hash-based source_id
- Results in more specific, meaningful titles for each source

* Skip AI title generation when display name is available

- Use source_display_name directly as title to avoid unnecessary AI calls
- More efficient and predictable than AI-generated titles
- Keep AI generation only as fallback for backward compatibility

* Fix critical issues from code review

- Add missing os import to prevent NameError crash
- Remove unused imports (pytest, Mock, patch, hashlib, urlparse, etc.)
- Fix GitHub API capitalization consistency
- Reuse existing DocumentStorageService instance
- Update test expectations to match corrected capitalization

Addresses CodeRabbit review feedback on PR #472

* Add safety improvements from code review

- Truncate display names to 100 chars when used as titles
- Document hash collision probability (negligible for <1M sources)

Simple, pragmatic fixes per KISS principle

* Fix code extraction to use hash-based source_ids and improve display names

- Fixed critical bug where code extraction was using old domain-based source_ids
- Updated code extraction service to accept source_id as parameter instead of extracting from URL
- Added special handling for llms.txt and sitemap.xml files in display names
- Added comprehensive tests for source_id handling in code extraction
- Removed unused urlparse import from code_extraction_service.py

This fixes the foreign key constraint errors that were preventing code examples
from being stored after the source_id architecture refactor.

* Fix critical variable shadowing and source_type determination issues

- Fixed variable shadowing in document_storage_operations.py where source_url parameter

- Fixed source_type determination to use actual URLs instead of hash-based source_id
- Added comprehensive tests for source URL preservation
- Ensure source_type is correctly set to "file" for file uploads, "url" for web crawls

The variable shadowing bug was causing sitemap sources to have the wrong source_url
(last crawled page instead of sitemap URL). The source_type bug would mark all
sources as "url" even for file uploads due to hash-based IDs not starting with "file_".

* Fix URL canonicalization and document metrics calculation

- Implement proper URL canonicalization to prevent duplicate sources
  - Remove trailing slashes (except root)
  - Remove URL fragments
  - Remove tracking parameters (utm_*, gclid, fbclid, etc.)
  - Sort query parameters for consistency
  - Remove default ports (80 for HTTP, 443 for HTTPS)
  - Normalize scheme and domain to lowercase

- Fix avg_chunks_per_doc calculation to avoid division by zero
  - Track processed_docs count separately from total crawl_results
  - Handle all-empty document sets gracefully
  - Show processed/total in logs for better visibility

- Add comprehensive tests for both fixes
  - 10 test cases for URL canonicalization edge cases
  - 4 test cases for document metrics calculation

This prevents database constraint violations when crawling the same
content with URL variations and provides accurate metrics in logs.

* Fix synchronous extract_source_summary blocking async event loop

- Run extract_source_summary in thread pool using asyncio.to_thread
- Prevents blocking the async event loop during AI summary generation
- Preserves exact error handling and fallback behavior
- Variables (source_id, combined_content) properly passed to thread

Added comprehensive tests verifying:
- Function runs in thread without blocking
- Error handling works correctly with fallback
- Multiple sources can be processed
- Thread safety with variable passing

* Fix synchronous update_source_info blocking async event loop

- Run update_source_info in thread pool using asyncio.to_thread
- Prevents blocking the async event loop during database operations
- Preserves exact error handling and fallback behavior
- All kwargs properly passed to thread execution

Added comprehensive tests verifying:
- Function runs in thread without blocking
- Error handling triggers fallback correctly
- All kwargs are preserved when passed to thread
- Existing extract_source_summary tests still pass

* Fix race condition in source creation using upsert

- Replace INSERT with UPSERT for new sources to prevent PRIMARY KEY violations
- Handles concurrent crawls attempting to create the same source
- Maintains existing UPDATE behavior for sources that already exist

Added comprehensive tests verifying:
- Concurrent source creation doesn't fail
- Upsert is used for new sources (not insert)
- Update is still used for existing sources
- Async concurrent operations work correctly
- Race conditions with delays are handled

This prevents database constraint errors when multiple crawls target
the same URL simultaneously.

* Add migration detection UI components

Add MigrationBanner component with clear user instructions for database schema updates. Add useMigrationStatus hook for periodic health check monitoring with graceful error handling.

* Integrate migration banner into main app

Add migration status monitoring and banner display to App.tsx. Shows migration banner when database schema updates are required.

* Enhance backend startup error instructions

Add detailed Docker restart instructions and migration script guidance. Improves user experience when encountering startup failures.

* Add database schema caching to health endpoint

Implement smart caching for schema validation to prevent repeated database queries. Cache successful validations permanently and throttle failures to 30-second intervals. Replace debug prints with proper logging.

* Clean up knowledge API imports and logging

Remove duplicate import statements and redundant logging. Improves code clarity and reduces log noise.

* Remove unused instructions prop from MigrationBanner

Clean up component API by removing instructions prop that was accepted but never rendered. Simplifies the interface and eliminates dead code while keeping the functional hardcoded migration steps.

* Add schema_valid flag to migration_required health response

Add schema_valid: false flag to health endpoint response when database schema migration is required. Improves API consistency without changing existing behavior.

4004090b45 Fix critical issues from code review 
- Use python-jose (already in dependencies) instead of PyJWT for JWT decoding
- Make unknown Supabase key roles fail fast per alpha principles
- Skip all JWT validations (not just signature) when checking role
- Update tests to expect failure for unknown roles

Fixes:
- No need to add PyJWT dependency - python-jose provides JWT functionality
- Unknown key types now raise ConfigurationError instead of warning
- JWT decode properly skips all validations to only check role claim

3800280f2e Add Supabase key validation and simplify frontend state management 
- Add backend validation to detect and warn about anon vs service keys
- Prevent startup with incorrect Supabase key configuration
- Consolidate frontend state management following KISS principles
- Remove duplicate state tracking and sessionStorage polling
- Add clear error display when backend fails to start
- Improve .env.example documentation with detailed key selection guide
- Add comprehensive test coverage for validation logic
- Remove unused test results checking to eliminate 404 errors

The implementation now warns users about key misconfiguration while
maintaining backward compatibility. Frontend state is simplified with
MainLayout as the single source of truth for backend status.

8157670936 Fix crawler attempting to navigate to binary files 
- Add is_binary_file() method to URLHandler to detect 40+ binary extensions
- Update RecursiveCrawlStrategy to filter binary URLs before crawl queue
- Add comprehensive unit tests for binary file detection
- Prevents net::ERR_ABORTED errors when crawler encounters ZIP, PDF, etc.

This fixes the issue where the crawler was treating binary file URLs
(like .zip downloads) as navigable web pages, causing errors in crawl4ai.
