study synthesis on memory deletion verification methods

Current research and industry practice show that proving complete memory deletion across caches, embeddings, and derived artifacts remains a hard systems problem (NIST data governance resources).

evidence map

• Point-in-time checks miss delayed replication paths.
• Cryptographic attestations improve confidence but add complexity.
• Continuous verification outperforms periodic manual checks.

method boundary

Verification quality depends on unified artifact inventories and event lineage.

my take

Deletion verification is becoming a defining challenge for trustworthy long-lived AI systems.
