Ghost vectors
thecontinuitylayer.com/glossary/ghost-vectorsThe definition
Embeddings that a vector database marked deleted but kept on disk. In 2026 tests, flagged vectors read from ChromaDB, FAISS and Weaviate storage files were inverted back to names, locations and patient data. An API delete that only flags is rung 5 of the erasure ladder, not rung 7.
The same words the glossary hub and the public data mirror carry; this page is the stable address for the term.
