* fix(knowledge): invalidate summary cache after mutations

Ensure /api/knowledge-items/summary ETag cache is invalidated after all
knowledge item operations to prevent stale UI data. This fixes cases where
users wouldn't see their changes (deletes, updates, crawls, uploads)
reflected in the main knowledge base listing until manual refresh.

* fix(ui): improve useToast hook type safety and platform compatibility

- Add removeToast to ToastContextType interface to fix type errors
- Update ToastProvider to expose removeToast in context value
- Use platform-agnostic setTimeout instead of window.setTimeout for SSR/test compatibility
- Fix timeout typing with ReturnType<typeof setTimeout> for accuracy across environments
- Use null-safe check (!=null) for timeout ID validation to handle edge cases

* fix(ui): add compile-time type safety to Button component variants and sizes

Add type aliases and Record typing to prevent runtime styling errors:
- ButtonVariant type ensures all variant union members have implementations
- ButtonSize type ensures all size union members have implementations
- Prevents silent failures when variants/sizes are added to types but not objects

* style: apply biome formatting to features directory

- Alphabetize exports in UI primitives index

- Update isinstance() to use union syntax (int | float)
- Change default status from "running" to "starting" for validation compliance
- Remove redundant field mapping logic handled by detail_field_mappings
- Fix whitespace and formatting issues

All progress models now use modern Pydantic v2 patterns while maintaining
backward compatibility for field name aliases.

* fix: improve progress API error handling and HTTP compliance

- Use RFC 7231 date format for Last-Modified header instead of ISO8601
- Add ProgressTracker.list_active() method for proper encapsulation
- Replace direct access to _progress_states with public method
- Add exc_info=True to error logging for better stack traces
- Fix exception chaining with proper 'from' clause
- Clean up docstring formatting and whitespace

Enhances debugging capability and follows HTTP standards while
maintaining proper class encapsulation patterns.

* 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.

* fix: improve document storage progress callbacks and error handling

- Standardize progress callback parameters (current_batch vs batch, event vs type)
- Remove redundant credential_service import
- Add graceful cancellation progress reporting at all cancellation check points
- Fix closure issues in embedding progress wrapper
- Replace bare except clauses with Exception
- Remove unused enable_parallel variable

* fix: standardize cancellation handling across all crawling strategies

- Add graceful cancellation logging to sitemap strategy
- Add cancellation progress reporting to document storage operations
- Add cancellation progress reporting to code extraction service
- Ensure consistent UX during cancellation across entire crawling system
- Fix trailing whitespace and formatting issues

All cancellation points now report progress before re-raising CancelledError,
matching the pattern established in document storage and recursive crawling.

* refactor: reduce verbose logging and extract duplicate progress patterns

- Reduce verbose debug logging in document storage callback by ~70%
  * Log only significant milestones (5% progress changes, status changes, start/end)
  * Prevents log flooding during heavy crawling operations

- Extract duplicate progress update patterns into helper function
  * Create update_crawl_progress() helper to eliminate 4 duplicate blocks
  * Consistent progress mapping and error handling across all crawl types
  * Improves maintainability and reduces code drift

This addresses CodeRabbit suggestions for log noise reduction and code duplication
while maintaining essential debugging capabilities and progress reporting accuracy.

- Add proper spacing between description text and footer buttons
- Update TasksTab to provide onOpenChange prop explicitly

* style: fix trailing whitespace in apiWithEtag comment

* fix: use end_progress parameter instead of hardcoded 100 in single_page crawl

- Replace hardcoded progress value with end_progress parameter
- Ensures proper progress range respect in crawl_markdown_file method

* fix: improve document processing error handling semantics and exception chaining

- Use ValueError for user errors (empty files, unsupported formats) instead of generic Exception
- Add proper exception chaining with 'from e' to preserve stack traces
- Remove fragile string-matching error detection anti-pattern
- Fix line length violations (155+ chars to <120 chars)
- Maintain semantic contract expected by knowledge API error handlers

* fix: critical index mapping bug in code storage service

- Track original_indices when building combined_texts to prevent data corruption
- Fix positions_by_text mapping to use original j indices instead of filtered k indices
- Change idx calculation from i + orig_idx to orig_idx (now global index)
- Add safety check to skip database insertion when no valid records exist
- Move collections imports to module top for clarity

Prevents embeddings being associated with wrong code examples when empty
code examples are skipped, which would cause silent search result corruption.

* fix: use RuntimeError with exception chaining for database failures

- Replace bare Exception with RuntimeError for source creation failures
- Preserve causal chain with 'from fallback_error' for better debugging
- Remove redundant error message duplication in exception text

Follows established backend guidelines for specific exception types
and maintains full stack trace information.

* fix: eliminate error masking in code extraction with proper exception handling

- Replace silent failure (return 0) with RuntimeError propagation in code extraction
- Add exception chaining with 'from e' to preserve full stack traces
- Update crawling service to catch code extraction failures gracefully
- Continue main crawl with clear warning when code extraction fails
- Report code extraction failures to progress tracker for user visibility

Follows backend guidelines for "detailed errors over graceful failures"
while maintaining batch processing resilience.

* fix: add error status to progress models to prevent validation failures

- Add "error" status to UploadProgressResponse and ProjectCreationProgressResponse
- Fix runtime bug where ProgressTracker.error() caused factory fallback to BaseProgressResponse
- Upload error responses now preserve specific fields (file_name, chunks_stored, etc)
- Add comprehensive status validation tests for all progress models
- Update CrawlProgressResponse test to include missing "error" and "stopping" statuses

This resolves the critical validation bug that was masked by fallback behavior
and ensures consistent API response shapes when operations fail.

* fix: prevent crashes from invalid batch sizes and enforce source_id integrity

- Clamp all batch sizes to minimum of 1 to prevent ZeroDivisionError and range step=0 errors
- Remove dangerous URL-based source_id fallback that violates foreign key constraints
- Skip chunks with missing source_id to maintain referential integrity with archon_sources table
- Apply clamping to batch_size, delete_batch_size, contextual_batch_size, max_workers, and fallback_batch_size
- Remove unused urlparse import

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

* fix: add configuration value clamping for crawl settings

Prevent crashes from invalid crawl configuration values:
- Clamp batch_size to minimum 1 (prevents range() step=0 crash)
- Clamp max_concurrent to minimum 1 (prevents invalid parallelism)
- Clamp memory_threshold to 10-99% (keeps dispatcher within bounds)
- Log warnings when values are corrected to alert admins

* fix: improve StatPill accessibility by removing live region and using standard aria-label

- Remove role="status" which created unintended ARIA live region announcements on every re-render
- Replace custom ariaLabel prop with standard aria-label attribute
- Update KnowledgeCard to use aria-label instead of ariaLabel
- Allows callers to optionally add role/aria-live attributes when needed

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

* fix: respect user cancellation in code summary generation

Remove exception handling that converted CancelledError to successful
return with default summaries. Now properly propagates cancellation
to respect user intent instead of silently continuing with defaults.

This aligns with fail-fast principles and improves user experience
when cancelling long-running code extraction operations.
