Interactive Graph Browser

A local, self-contained graph explorer (scripts/graph_browser.py in the orchestrata-ultimate repo) in the style of Neo4j Browser's graph view:

• Force-directed layout — nodes float and are draggable; wheel/buttons zoom and pan.
• +/− badge on each node expands (fetches neighbors + relationships live) or collapses it.
• Colors by node label with a clickable legend (label → seed nodes); side panel shows a node's properties; search box queries by name.
• Read-only — it never writes to the graphs.

How the browser, server, and the two graphs connect:

Launch

cd ~/workspace/orchestrata-ultimate-architecture
uv run python scripts/graph_browser.py --host 127.0.0.1 --port 8090
# then open http://127.0.0.1:8090/

Data sources

• Default: the shared Memgraph HA cluster (resolved from MEMGRAPH_URI — the orchgraph Raft coordinator routing URI neo4j://10.53.1.160:7691, which routes to the current MAIN; a legacy MEMGRAPH_HA_CONTROLLER_URL is honored first if set; unauthenticated via the NO_AUTH factory sentinel) — wiki graph + orchestrata semantic graph, including the enhancement layer (Entity nodes sub-labeled Spec/Requirement/Story/CodeElement with IMPLEMENTS/HAS_REQUIREMENT edges).
• ?graph=neo4j — the Neo4j knowledge graph (code intelligence), resolved from NEO4J_URI env.

D3 v7 is vendored (scripts/static/d3.v7.min.js) — no CDN, works offline.
