refactor: Phase 5 - Remove manual cache invalidations (#707) 
* chore, cleanup leftovers of tanstack refactoring

* refactor: Complete Phase 5 - Remove manual cache invalidations

- Removed all manual cache invalidations from knowledge queries
- Updated task queries to rely on backend consistency
- Fixed optimistic update utilities to handle edge cases
- Cleaned up unused imports and test utilities
- Fixed minor TypeScript issues in UI components

Backend now ensures data consistency through proper transaction handling,
eliminating the need for frontend cache coordination.


* docs: Enhance TODO comment for knowledge optimistic update issue

- Added comprehensive explanation of the query key mismatch issue
- Documented current behavior and impact on user experience
- Listed potential solutions with tradeoffs
- Created detailed PRP story in PRPs/local/ for future implementation
- References specific line numbers and implementation details

This documents a known limitation where optimistic updates to knowledge
items are invisible because mutations update the wrong query cache.

refactor: Phase 2 Query Keys Standardization - Complete TanStack Query v5 patterns implementation (#692) 
* refactor: complete Phase 2 Query Keys Standardization

Standardize query keys across all features following vertical slice architecture,
ensuring they mirror backend API structure exactly with no backward compatibility.

Key Changes:
- Refactor all query key factories to follow consistent patterns
- Move progress feature from knowledge/progress to top-level /features/progress
- Create shared query patterns for consistency (DISABLED_QUERY_KEY, STALE_TIMES)
- Remove all hardcoded stale times and disabled keys
- Update all imports after progress feature relocation

Query Key Factories Standardized:
- projectKeys: removed task-related keys (tasks, taskCounts)
- taskKeys: added dual nature support (global via lists(), project-scoped via byProject())
- knowledgeKeys: removed redundant methods (details, summary)
- progressKeys: new top-level feature with consistent factory
- documentKeys: full factory pattern with versions support
- mcpKeys: complete with health endpoint

Shared Patterns Implementation:
- STALE_TIMES: instant (0), realtime (3s), frequent (5s), normal (30s), rare (5m), static (∞)
- DISABLED_QUERY_KEY: consistent disabled query pattern across all features
- Removed unused createQueryOptions helper

Testing:
- Added comprehensive tests for progress hooks
- Updated all test mocks to include new STALE_TIMES values
- All 81 feature tests passing

Documentation:
- Created QUERY_PATTERNS.md guide for future implementations
- Clear patterns, examples, and migration checklist

Breaking Changes:
- Progress imports moved from knowledge/progress to progress
- Query key structure changes (cache will reset)
- No backward compatibility maintained

- Update all UI components to use metadata.tags exclusively
- Fix mutations to correctly update tags in metadata object
- Remove duplicate tags field from backend KnowledgeSummaryService
- Fix test setup issue with QueryClient instance in knowledge tests
- Add TODO comments for filter-blind optimistic updates (Phase 3)

This eliminates the ambiguity identified in Phase 2 where both item.tags
and metadata.tags existed, establishing metadata.tags as the single
source of truth across the entire stack.

* fix: comprehensive progress hooks improvements

- Integrate useSmartPolling for all polling queries
- Fix memory leaks from uncleaned timeouts
- Replace string-based error checking with status codes
- Remove TypeScript any usage with proper types
- Fix unstable dependencies with sorted JSON serialization
- Add staleTime to document queries for consistency

* feat: implement flexible assignee system for dynamic agents

- Changed assignee from restricted enum to flexible string type
- Renamed "AI IDE Agent" to "Coding Agent" for clarity
- Enhanced ComboBox with Radix UI best practices:
  - Full ARIA compliance (roles, labels, keyboard nav)
  - Performance optimizations (memoization, useCallback)
  - Improved UX (auto-scroll, keyboard shortcuts)
  - Fixed event bubbling preventing unintended modal opens
- Updated MCP server docs to reflect flexible assignee capability
- Removed unnecessary UI elements (arrows, helper text)
- Styled ComboBox to match priority selector aesthetic

This allows external MCP clients to create and assign custom sub-agents
dynamically, supporting advanced agent orchestration workflows.

refactor: remove ETag Map cache layer for TanStack Query single source of truth (#676) 
* refactor: remove ETag Map cache layer for TanStack Query single source of truth

- Remove Map-based cache from apiWithEtag.ts to eliminate double-caching anti-pattern
- Move apiWithEtag.ts to shared location since used across multiple features
- Implement NotModifiedError for 304 responses to work with TanStack Query
- Remove invalidateETagCache calls from all service files
- Preserve browser ETag headers for bandwidth optimization (70-90% reduction)
- Add comprehensive test coverage (10 test cases)
- All existing functionality maintained with zero breaking changes

This addresses Phase 1 of frontend state management refactor, making TanStack Query
the sole authority for cache decisions while maintaining HTTP 304 performance benefits.

* fix: increase API timeout to 20s for large delete operations

Temporary fix for database performance issue where DELETE operations on
crawled_pages table with 7K+ rows take 13+ seconds due to sequential scan.

Root cause analysis:
- Source '9529d5dabe8a726a' has 7,073 rows (98% of crawled_pages table)
- PostgreSQL uses sequential scan instead of index for large deletes
- Operation takes 13.4s but frontend timeout was 10s
- Results in frontend errors while backend eventually succeeds

This prevents timeout errors during knowledge item deletion until we
implement proper batch deletion or database optimization.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor: complete simplification of ETag handling (Option 3)

- Remove all explicit ETag handling code from apiWithEtag.ts
- Let browser handle ETags and 304 responses automatically
- Remove NotModifiedError class and associated retry logic
- Simplify QueryClient retry configuration in App.tsx
- Add comprehensive tests documenting browser caching behavior
- Fix missing generic type in knowledgeService searchKnowledgeBase

This completes Phase 1 of the frontend state management refactor.
TanStack Query is now the single source of truth for caching,
while browser handles HTTP cache/ETags transparently.

Benefits:
- 50+ lines of code removed
- Zero complexity for 304 handling
- Bandwidth optimization maintained (70-90% reduction)
- Data freshness guaranteed
- Perfect alignment with TanStack Query philosophy

* fix: resolve DOM nesting validation error in ProjectCard

Changed ProjectCard from motion.li to motion.div since it's already
wrapped in an li element by ProjectList. This fixes the React warning
about li elements being nested inside other li elements.

* fix: properly unwrap task mutation responses from backend

The backend returns wrapped responses for mutations:
{ message: string, task: Task }

But the frontend was expecting just the Task object, causing
description and other fields to not persist properly.

Fixed by:
- Updated createTask to unwrap response.task
- Updated updateTask to unwrap response.task
- Updated updateTaskStatus to unwrap response.task

This ensures all task data including descriptions persist correctly.

* test: add comprehensive tests for task service response unwrapping

Added 15 tests covering:
- createTask with response unwrapping
- updateTask with response unwrapping
- updateTaskStatus with response unwrapping
- deleteTask (no unwrapping needed)
- getTasksByProject (direct response)
- Error handling for all methods
- Regression tests ensuring description persistence
- Full field preservation when unwrapping responses

These tests verify that the backend's wrapped mutation responses
{ message: string, task: Task } are properly unwrapped to return
just the Task object to consumers.

* fix: add explicit event propagation stopping in ProjectCard

Added e.stopPropagation() at the ProjectCard level when passing
handlers to ProjectCardActions for pin and delete operations.

This provides defense in depth even though ProjectCardActions
already stops propagation internally. Ensures clicking action
buttons never triggers card selection.

* refactor: consolidate error handling into shared module

- Create shared/errors.ts with APIServiceError, ValidationError, MCPToolError
- Move error classes and utilities from projects/shared/api to shared location
- Update all imports to use shared error module
- Fix cross-feature dependencies (knowledge no longer depends on projects)
- Apply biome formatting to all modified files

This establishes a clean architecture where common errors are properly
located in the shared module, eliminating feature coupling.

* test: improve test isolation and clean up assertions

- Preserve and restore global AbortSignal and fetch to prevent test pollution
- Rename test suite from "Simplified API Client (Option 3)" to "apiWithEtag"
- Optimize duplicate assertions by capturing promises once
- Use toThrowError with specific error instances for better assertions

This ensures tests don't affect each other and improves test maintainability.

* refactor: Remove unused callAPI function and document 304 handling approach

- Delete unused callAPI function from projects/shared/api.ts (56 lines of dead code)
- Keep only the formatRelativeTime utility that's actively used
- Add comprehensive documentation explaining why we don't handle 304s explicitly
- Document that browser handles ETags/304s transparently and we use TanStack Query for cache control
- Update apiWithEtag.ts header to clarify the simplification strategy

This follows our beta principle of removing dead code immediately and maintains our simplified approach to HTTP caching where the browser handles 304s automatically.

* docs: Fix comment drift and clarify ETag/304 handling documentation

- Update header comment to be more technically accurate about Fetch API behavior
- Clarify that fetch (not browser generically) returns cached responses for 304s
- Explicitly document that we don't add If-None-Match headers
- Add note about browser's automatic ETag revalidation

These documentation updates prevent confusion about our simplified HTTP caching approach.

Fix Issue #362: Provider-agnostic error handling for all LLM providers (#650) 
* feat: Provider-agnostic error handling for Issue #362

Implements generic error handling that works for OpenAI, Google AI,
Anthropic, and other LLM providers to prevent silent failures.

Essential files only:
1. Provider error adapters (new) - handles any LLM provider
2. Backend API key validation - detects invalid keys before operations
3. Frontend error handler - provider-aware error messages
4. Updated hooks - uses generic error handling

Core functionality:
✅ Validates API keys before expensive operations (crawl, upload, refresh)
✅ Shows clear provider-specific error messages
✅ Works with OpenAI: 'Please verify your OpenAI API key in Settings'
✅ Works with Google: 'Please verify your Google API key in Settings'
✅ Prevents 90-minute debugging sessions from Issue #362

No unnecessary changes - only essential error handling logic.

Fixes #362

* fix: Enhance API key validation with detailed logging and error handling

- Add comprehensive logging to trace validation flow
- Ensure validation actually blocks operations on authentication failures
- Improve error detection to catch wrapped OpenAI errors
- Fail fast on any validation errors to prevent wasted operations

This should ensure invalid API keys are caught before crawl starts,
not during embedding processing after documents are crawled.

* fix: Simplify API key validation to always fail on exceptions

- Remove complex provider adapter imports that cause module issues
- Simplified validation that fails fast on any embedding creation error
- Enhanced logging to trace exactly what's happening
- Always block operations when API key validation fails

This ensures invalid API keys are caught immediately before
crawl operations start, preventing silent failures.

* fix: Add API key validation to refresh and upload endpoints

The validation was only added to new crawl endpoint but missing from:
- Knowledge item refresh endpoint (/knowledge-items/{source_id}/refresh)
- Document upload endpoint (/documents/upload)

Now all three endpoints that create embeddings will validate API keys
before starting operations, preventing silent failures on refresh/upload.

* security: Implement core security fixes from CodeRabbit review

Enhanced sanitization and provider detection based on CodeRabbit feedback:

✅ Comprehensive regex patterns for all provider API keys
  - OpenAI: sk-[a-zA-Z0-9]{48} with case-insensitive matching
  - Google AI: AIza[a-zA-Z0-9_-]{35} with flexible matching
  - Anthropic: sk-ant-[a-zA-Z0-9_-]{10,} with variable length

✅ Enhanced provider detection with multiple patterns
  - Case-insensitive keyword matching (openai, google, anthropic)
  - Regex-based API key detection for reliable identification
  - Additional keywords (gpt, claude, vertex, googleapis)

✅ Improved sanitization patterns
  - Provider-specific URL sanitization (openai.com, googleapis.com, anthropic.com)
  - Organization and project ID redaction
  - OAuth token and bearer token sanitization
  - Sensitive keyword detection and generic fallback

✅ Sanitized error logging
  - All error messages sanitized before logging
  - Prevents sensitive data exposure in backend logs
  - Maintains debugging capability with redacted information

Core security improvements while maintaining simplicity for beta deployment.

* fix: Replace ad-hoc error sanitization with centralized ProviderErrorFactory

- Remove local _sanitize_provider_error implementation with inline regex patterns
- Add ProviderErrorFactory import from embeddings.provider_error_adapters
- Update _validate_provider_api_key calls to pass correct active embedding provider
- Replace sanitization call with ProviderErrorFactory.sanitize_provider_error()
- Eliminate duplicate logic and fixed-length key assumptions
- Ensure provider-specific, configurable sanitization patterns are used consistently

* fix: eliminate all -1 progress values to ensure 0-100 range compliance

This comprehensive fix addresses CodeRabbit's suggestion to avoid negative
progress values that violate Pydantic model constraints (Field(ge=0, le=100)).

## Changes Made:

**ProgressMapper (Core Fix):**
- Error and cancelled states now preserve last known progress instead of returning -1
- Maintains progress context when operations fail or are cancelled

**Services (Remove Hard-coded -1):**
- CrawlingService: Use ProgressMapper for error/cancelled progress values
- KnowledgeAPI: Preserve current progress when cancelling operations
- All services now respect 0-100 range constraints

**Tests (Updated Behavior):**
- Error/cancelled tests now expect preserved progress instead of -1
- Progress model tests updated for new "starting" default status
- Added comprehensive test coverage for error state preservation

**Data Flow:**
- Progress: ProgressMapper -> Services -> ProgressTracker -> API -> Pydantic Models
- All stages now maintain valid 0-100 range throughout the flow
- Better error context preservation for debugging

## Impact:
- ✅ Eliminates Pydantic validation errors from negative progress values
- ✅ Preserves meaningful progress context during errors/cancellation
- ✅ Follows "detailed errors over graceful failures" principle
- ✅ Maintains API consistency with 0-100 progress range

Resolves progress value constraint violations while improving error handling
and maintaining better user experience with preserved progress context.

* fix: use deduplicated URL count for accurate recursive crawl progress

Initialize total_discovered from normalized & deduplicated current_urls
instead of raw start_urls to prevent progress overcounting.

## Issue:
When start_urls contained duplicates or URL fragments like:
- ["http://site.com", "http://site.com#section"]

The progress system would report "1/2 URLs processed" when only
1 unique URL was actually being crawled, confusing users.

## Solution:
- Use len(current_urls) instead of len(start_urls) for total_discovered
- current_urls already contains normalized & deduplicated URLs
- Progress percentages now accurately reflect actual work being done

## Impact:
- ✅ Eliminates progress overcounting from duplicate/fragment URLs
- ✅ Shows accurate URL totals in crawl progress reporting
- ✅ Improves user experience with correct progress information
- ✅ Maintains all existing functionality while fixing accuracy

Example: 5 input URLs with fragments → 2 unique URLs = accurate 50% progress
instead of misleading 20% progress from inflated denominator.
