notebook-llmgraph-update-pattern

Missing NotebookLLMGraph nodes occur when external package updates are not flushed correctly, requiring synchronization of in-memory cache writes with TaggingRules persistence to guarantee immediate consistency.

To ensure cache consistency when updating NotebookLLMGraph nodes from an external package, follow the cache-update-then-flush pattern: write to $iLLMGraphCache/$iLLMGraphCacheNB, then call iLLMGraphFlush to persist to TaggingRules.

The correct sequence for recording state-graph runtime nodes is to write to $iLLMGraphCache/$iLLMGraphCacheNB first, then call iLLMGraphFlush to synchronize the in-memory cache with TaggingRules persistence for immediate visibility.

Debug cache and flush mismatches during third-party package integration by using dynamic key detection and cache dump helpers to verify that $iLLMGraphCache writes properly precede iLLMGraphFlush calls in the NotebookLLMGraph workflow.

Yes, integrating third-party packages that mutate LLM graph nodes during state-graph recording requires the cache-update-then-flush pattern ($iLLMGraphCache/$iLLMGraphCacheNB then iLLMGraphFlush) to maintain NotebookLLMGraph consistency.

Relying solely on in-memory cache without calling iLLMGraphFlush limits NotebookLLMGraph updates to temporary state, preventing TaggingRules persistence and causing newly added nodes to remain invisible in subsequent queries.
