Deleting an original file is only one step in removing information from a knowledge assistant.

Search indexes, extracted text, previews, summaries, and traces may still contain related copies or expose an old answer.

Map the derived data and every route that can display it. Distinguish stopping access from physically erasing each stored copy.

Use identifiable synthetic material to test removal through search, direct links, caches, and restored backups. Keep unresolved locations visible.

Repeat the test after architecture changes. Explain what was suppressed, what was erased, and what follows a separate retention process, rather than promising instant universal deletion.
