Pipeline fixes:
- Fix agent getting empty response from graph-rag by combining answer +
explain data in single message (RequestResponse returns first msg)
- Fix Doc RAG pipeline: add content field to Qdrant doc payload, seed 10
document chunks, fix type mismatches across base/flow/client
- Forward explainability events from agent's KnowledgeQuery to client
- Add "agent" to TERM_BEARING_RESPONSE_SERVICES for triple translation
- Fix embeddings env var (OLLAMA_URL), user/collection threading, edge
scoring threshold, and various protocol mismatches
Branding:
- Rename TrustGraph → Beep Graph (title, sidebar, settings, about)
- Custom lambda + ThugLife pixel glasses SVG logo component
- Forest green color palette (brand-50 through brand-900)
- SVG favicon + PNG icons (16/32/180/192/512)
- PWA manifest with service worker for offline shell caching
- Splash screen with animated logo pulse on app load
- Ambient glow background with drifting green radial blobs

Add the full MCP tool pipeline enabling agents to invoke external tools
(like Brave Search) via MCP servers:
- Add ToolRequest/ToolResponse types and mcp-tool topics to @trustgraph/base
- Create McpToolService (FlowProcessor) that connects to external MCP servers
via @modelcontextprotocol/sdk StreamableHTTP transport
- Add createMcpTool() to wire MCP tools into the agent's ReAct loop
- Implement config-driven tool registration in AgentService with backward-
compatible fallback to hardcoded tools
- Add tool filtering by group and state (port of Python tool_filter.py)
- Register mcp-tool in gateway dispatcher and export from @trustgraph/flow
- Fix flow restart race condition: skip restart when flow definitions unchanged
- Update seed config with MCP server config and tool definitions
- Add run scripts for MCP tool service and Brave Search MCP server

- Fix FalkorDB triples query: client v5 returns objects not arrays, use named field access
- Fix embeddings service: align spec names to "embeddings-request"/"embeddings-response"
- Fix client triplesQuery: read `triples` field instead of `response` from backend
- Fix graph page crash: guard against non-array triples, accept literals as entity nodes
- Add seed:demo script for AI industry knowledge graph (254 triples, 64 entities)

Add full pipeline test that generates a real PDF, processes it through
the entire pipeline, and verifies knowledge lands in FalkorDB:
- Create test PDF generator using pdf-lib (2-page doc about Acme Corp)
- Add testFullPipeline() to integration tests with store verification
- Fix FalkorDB client connect() — createClient returns unconnected client
in both TriplesStore and TriplesQuery classes
Results: PDF decoded (2 pages) → chunked (2 chunks) → extracted
(4 relationships) → 16 triples stored in FalkorDB including:
alice-johnson → is-a-senior-engineer → acme-corporation
cloudsync → uses-aws-for-hosting → amazon-web-services
provenance: pages → prov:wasDerivedFrom → source document

Wire up the query and retrieval side of the pipeline so the agent can
answer questions from stored knowledge:
- Triples query service (FalkorDB) — all SPO pattern queries via NATS
- Graph embeddings query service (Qdrant) — entity vector similarity
- Document embeddings query service (Qdrant) — chunk vector similarity
- Graph RAG service — full concept→entity→traverse→score→synthesize pipeline
- Document RAG service — embed→find chunks→synthesize pipeline
- Runner scripts for chunker, extractor, embeddings (missing from Phase 5)
- Add DocumentEmbeddingsRequest/Response schema types
- Add RAG prompt templates (extract-concepts, edge-scoring, synthesize)
- Add graph/doc embeddings query topics to seed config + flow manager
- Add all pipeline/query/retrieval services to docker-compose
- 8 new runner scripts, 8 new pnpm script aliases

Add end-to-end document processing pipeline:
- PDF decoder service (pdfjs-dist) extracts text per page from librarian docs
- Ollama native LLM service for local model inference
- FalkorDB triples store FlowProcessor consumer
- Qdrant graph embeddings store FlowProcessor consumer
- Fix spec name collisions in chunker/extractor (input→chunk-input, etc.)
- Gateway /load endpoint to trigger document processing
- Align flow manager blueprint and seed config with full pipeline topics
- Add runner scripts and test coverage for document load

Flow Management Service:
- FlowManagerService (AsyncProcessor) handling list/get/start/stop flows
and list/get blueprints via kebab-case wire format
- Default blueprint with all service topic mappings
- Pushes flow config to config service on start/stop
Config Seeding:
- seed-config.ts script pushes prompt templates (extract-relationships,
extract-definitions, document-prompt, kg-prompt) and default flow
definition via gateway REST API
Integration Tests:
- Librarian CRUD: add-document, list-documents, get-content, delete
- Agent query: verifies routing through gateway to agent service
- Skip flags: SKIP_LIBRARIAN=1, SKIP_AGENT=1

Fix three critical bugs preventing the NATS message pipeline from working:
- FlowProcessor now subscribes to config-push topic (was missing entirely),
using DeliverPolicy.All to replay config on service restart
- NATS streams use wildcard subjects (tg.flow.>) instead of per-topic
narrow filters that caused 503 errors on publish
- Subscriber dispatch loop has exponential backoff on errors to prevent
tight error loops
Add service runner scripts (gateway, config, LLM) and a 7-test
integration suite that verifies config CRUD, WebSocket round-trip,
and full LLM text-completion through the NATS pipeline.
Fix Docker Compose infra: pin Tempo to v2.6.1, remove deprecated Loki
config fields, add user:0 for volume permissions, remap conflicting
ports (FalkorDB 6380, OTLP 4327/4328).
