Search-as-DreamNode Interface

[ProjectLiminality]

Description

Unified search and creation interface that treats search queries as temporary DreamNodes. Creates seamless UX where search becomes a central node in honeycomb layout, with results arranged by semantic similarity distance.

Parent Specification: #268 - Search Architecture Specification

✅ FEATURE COMPLETE

Status: All acceptance criteria implemented and tested successfully.

Implementation Summary

Core Architecture ✅

• SearchNode3D Component: Extends ProtoNode3D architecture for visual consistency
• Spawn Animation: Node flies in from sphere surface (5000 units) to focused position (50 units) using easeOutQuart over 1 second
• Visual Style: Blue Dream-type node with transparent text input (completely seamless)
• Title Field = Search Field: Search query input with auto-focus and debounced store updates

Search Update Mechanism ✅

• 1-Second Rhythm: Periodic checks every second for query changes via SearchOrchestrator
• Smart Debouncing: Ignores trivial changes (whitespace-only) with hasSignificantChange()
• Performance Optimized: Local state (300ms debounced) + store updates for immediate UI responsiveness
• Semantic Integration: Calls semantic search service on non-trivial query changes (2+ chars)

Spatial Integration ✅

• SpatialOrchestrator Enhancement: Added moveAllToSphereForSearch() and showSearchResults() methods
• Honeycomb Layout: Leverages existing honeycomb layout for search results display
• Consistent Animation: Uses existing movement API with standard easing patterns

Multi-Modal Support ✅

• Drag & Drop: Accept images, PDFs, and documents with proper event isolation
• File Type Detection: Reuses isValidMediaFile() logic from ProtoNode
• Additional Files: Support for multiple file attachments beyond DreamTalk

Interaction Design ✅

• Save Button: Below search node converts to permanent DreamNode with save animation
• Escape Key: Dismiss search, return to constellation
• Click Away: Click empty space or search results returns to constellation
• Conversion: Search query becomes DreamNode title, all files preserved

Acceptance Criteria ✅

• Search toggle command in command palette
• SearchNode3D spawns with smooth animation (5000→50 units, 1 second)
• Search input auto-focuses and updates every second on changes
• Semantic search integration shows results in honeycomb layout
• Drag-and-drop file support for multi-modal queries
• Save button converts search to permanent DreamNode
• Escape key and click-away dismissal working
• Consistent visual styling (blue Dream-type node)
• Performance optimized with debounced input architecture

Technical Implementation

Files Created ✅

• src/features/search/SearchNode3D.tsx - Main search UI component (495 lines)
• src/features/search/SearchOrchestrator.tsx - Periodic update logic (113 lines)

Files Enhanced ✅

• src/dreamspace/SpatialOrchestrator.tsx - Added search interface methods
• src/store/interbrain-store.ts - Enhanced search state management
• src/dreamspace/DreamspaceCanvas.tsx - Integrated search-as-DreamNode rendering
• src/main.ts - Search commands integration

Key Technical Achievements

Professional UX Design ✅

• Completely Transparent Text Input: No background, border, or shadow
• Debounced Architecture: 300ms local state + store update separation
• Event Isolation: Proper click/drag event handling prevents interference
• Text Rendering: Fixed descender clipping with proper container sizing

Performance Optimizations ✅

• Local State Pattern: Immediate UI response with debounced backend updates
• Search Orchestration: 1-second rhythm prevents overwhelming Ollama processing
• Animation Coordination: Parallel save animation + constellation return
• Memory Efficient: Lightweight state management with cleanup

Integration Excellence ✅

• Spatial Coordination: Seamless integration with SpatialOrchestrator
• Service Layer: Clean integration with semantic search services
• File Handling: Robust drag-drop with proper file type detection
• State Management: Clean search interface state transitions
