CoordiNode v0.3.1 shipped three fixes that unblock SDK improvements:

  1. Wildcard relationship patterns — MATCH (n)-[r]->(m) now returns results.

    • LlamaIndex get_triplets() can drop the NotImplementedError for missing relation_names
    • LlamaIndex get_rel_map() can use wildcard instead of schema-lookup typed pattern
    • LangChain refresh_schema() can use wildcard instead of typed pattern

  2. MERGE for edge patterns — MERGE (src)-[r:TYPE]->(dst) works.

    • LlamaIndex upsert_relations() and LangChain _create_edge() can switch from CREATE to MERGE for idempotent edge upsert
    • LangChain _link_document_to_entities() MENTIONS edges can use MERGE

  3. Vector search via VectorService RPC — returns real results.

    • E2E integration tests needed for vector_search() / vector_query()

Also clean up stale workaround comments and docstrings that reference now-fixed limitations.
