A GitHub and package-registry cohort tests whether persistent agent memory is acquiring provenance, retention, deletion, access-control, and poisoning defenses.
266 subject-filtered implementations show that persistent memory is already a visible software category. Persistence appears in 15.4% of the cohort, but provenance or audit in 3.8%, retention controls in 1.5%, deletion in 2.3%, and poisoning defenses in 0.4%. Memory supply is growing faster than memory governance.
