- Add queryMode field to QueryLogSummary interface
- Update getQueryLogs to group by both query AND queryMode
- Use composite key (query|||queryMode) for proper separation
- Enables separate tracking of Pure RAG vs Graph Search queries
Previously, queries with the same text but different modes were
merged together, causing metrics to only show one aggregate value.
Now each mode's performance is tracked independently.

- Add triple structure logging in API route for debugging
- Update graph-db-service imports for multi-hop fields
- Improve embeddings generator UI responsiveness
- Enable data pipeline verification for depth/pathLength fields
These changes help diagnose issues with multi-hop data flow
and ensure proper propagation of metadata through the stack.

- Update default topK from 20 to 40 in query parameters
- Support richer context with multi-hop graph traversal
- Maintain flexible topK range (1-50) via slider
- Respect user selection of query mode (don't force mode changes)
Higher topK allows more edges from multi-hop paths to be included
in the context provided to the LLM for answer generation.

- Display hop number (0, 1, 2...) with network icon for each triple
- Show multi-hop path badge for paths with length > 1
- Add "Multi-hop enabled" badge in Retrieved Knowledge header
- Implement collapsible thinking steps with proper chevron rotation
- Parse <think> tags from NVIDIA reasoning content
- Reduce console logging (sample only, not full dataset)
- Show path length with amber lightning icon
This provides visual feedback about multi-hop reasoning paths
and makes the LLM's chain-of-thought process transparent.

- Extract ALL edges from graph traversal paths, not just endpoints
- Add depth field (edge position in path: 0, 1, 2...)
- Add pathLength field (total edges in path)
- Use numeric index iteration for AQL compatibility
- Apply depth penalty to edge scoring (earlier edges weighted higher)
- Enable visualization of knowledge chains in graph queries
- Increase topK default to 40 for richer multi-hop context
This allows Traditional Graph to show how information is connected
across multiple hops in the knowledge graph, similar to GraphRAG.

- Integrate NVIDIA API as alternative to Ollama for graph queries
- Implement thinking tokens API with /think system message
- Add min_thinking_tokens (1024) and max_thinking_tokens (2048)
- Format reasoning_content with <think> tags for UI parsing
- Support dynamic model/provider selection per query
- Maintain Ollama fallback for backward compatibility
This enables Traditional Graph to use NVIDIA's reasoning models
(e.g., nvidia-nemotron-nano-9b-v2) with visible chain-of-thought.
