Mnemosyne.Pipeline.Decay (mnemosyne v0.1.5)

Maintenance module that prunes low-utility nodes from the knowledge graph.

Scores all nodes of specified types using a relevance-free decay formula (recency frequency reward) and deletes those scoring below a threshold. After deletion, cleans up orphaned Tags and Intents that have no remaining children.
