Phase 5 Handlers (Not Registered)

⚠️ Physics Handler

  • File: src/handlers/physics_handler.rs
  • Export: ✅ Exported in handlers/mod.rs:37
  • Registration: ❌ Missing in main.rs
  • Impact: Physics API endpoints unreachable
  • Fix: Add .configure(configure_physics_routes) to main.rs:423

⚠️ Semantic Handler

  • File: src/handlers/semantic_handler.rs
  • Export: ✅ Exported in handlers/mod.rs:38
  • Registration: ❌ Missing in main.rs
  • Impact: Semantic analysis API endpoints unreachable
  • Fix: Add .configure(configure_semantic_routes) to main.rs:423

⚠️ Inference Handler

  • File: src/handlers/inference_handler.rs
  • Export: ✅ Exported in handlers/mod.rs:43
  • Registration: ❌ Missing in main.rs
  • Impact: Inference API endpoints unreachable
  • Fix: Add .configure(configure_inference_routes) to main.rs:423

Quick Fix:

// Add to main.rs around line 423
.configure(configure_physics_routes)
.configure(configure_semantic_routes)
.configure(configure_inference_routes)

Legacy Handlers (Files Exist, Commented Out)

⚠️ Cypher Query Handler

  • File: src/handlers/cypher_query_handler.rs (205 lines)
  • Status: Commented out in main.rs:418
  • Reason: "Handler deleted in Neo4j migration"
  • Reality: File still exists
  • Action: DELETE file or re-enable if needed

⚠️ Pipeline Admin Handler

  • File: src/handlers/pipeline_admin_handler.rs
  • Status: Commented out in main.rs:417
  • Reason: "SQLite-specific, removed in Neo4j migration"
  • Reality: File still exists
  • Action: DELETE file (no longer needed)

Other Disconnected Handlers

Handler File Impact Status
consolidated_health_handler consolidated_health_handler.rs MEDIUM Not registered
realtime_websocket_handler realtime_websocket_handler.rs MEDIUM Not registered
multi_mcp_websocket_handler multi_mcp_websocket_handler.rs MEDIUM Not registered
validation_handler validation_handler.rs MEDIUM Not registered
websocket_settings_handler websocket_settings_handler.rs MEDIUM Not registered
graph_state_handler_refactored graph_state_handler_refactored.rs LOW Development
settings_validation_fix settings_validation_fix.rs LOW Debug code?

Note: Some handlers (e.g., clustering_handler, constraints_handler) are registered via api_handler::config, not directly in main.rs.

Minor Issues

Backup Files (9 files)

Active Source Tree (DELETE):

  • src/handlers/settings_handler.rs.bak
  • src/handlers/api_handler/graph/mod.rs.backup
  • src/repositories/unified_graph_repository.rs.backup
  • client/src/features/settings/components/panels/SettingsPanelRedesign.tsx.backup

Data Backups (MOVE TO ARCHIVE):

  • data/metadata/metadata.json.backup

Archive Folder (OK):

  • archive/gpu_consolidation_2025_11_03/ (3 .cu.backup files)
  • archive/neo4j_migration_2025_11_03/ (1 .rs.backup file)

Client-Side TODOs (2 items)

1. Semantic Zoom Auto-Logic

File: client/src/features/visualisation/components/ControlPanel/SemanticZoomControls.tsx:46

// TODO: Implement auto-zoom logic based on camera distance

Impact: LOW Fix: Implement camera distance-based zoom calculation

2. Hardcoded Visualization Values

File: client/src/features/visualisation/components/HolographicDataSphere.tsx:27

// TODO: Map these hardcoded values to settings system

Impact: LOW Fix: Connect to settings API
