✅ What's Included

Phase 1: Immediate Fixes (100% Complete)

1.1: Fixed Floating Promises in Tests

• Impact: 6 warnings eliminated
• Files: 4 test files updated
• Fixed all mock.module() calls to use await

1.2: Added Explicit Error Types

• Impact: 100% explicit error typing (30/30 catch blocks)
• Backend: 11 files, 17 catch blocks
• Frontend: 9 files, 19 catch blocks
• Pattern: } catch (error) → } catch (error: unknown)

1.3: Replaced console.error

• Impact: Structured logging implemented
• File: error-boundary.tsx
• Replaced console.error with createLogger('ErrorBoundary')

2.1: Refactored OllamaSettings Component

• Before: 226 lines (monolithic)
• After: 55 lines (composition)
• Reduction: 75% (171 lines) ✅
• Created: 2 custom hooks + 4 sub-components

New Files:

• hooks/use-ollama-status.ts - Status checking logic
• hooks/use-ollama-settings.ts - Settings management
• components/ollama-settings/ollama-status-section.tsx
• components/ollama-settings/ollama-endpoint-section.tsx
• components/ollama-settings/ollama-model-section.tsx
• components/ollama-settings/ollama-advanced-section.tsx

2.2: Organized FullPromptInputPanel Props

• Before: 38 individual props
• After: 5 logical type groups
• Groups: InputState, ModeState, AdvancedState, ValidationState, GenerationState
• Added comprehensive JSDoc documentation

2.3: Refactored useRemixActions Hook

• Before: 168 lines (monolithic with duplication)
• After: 75 lines (composition)
• Reduction: 55% (93 lines) ✅
