Tamper-evident audit trail for mem0 memory operations

[jagmarques]

Built something that signs every memory add/search/update in mem0 with post-quantum cryptographic signatures, creating an immutable audit log.

The problem: if you store and retrieve agent memories, how do you prove later that a memory was not silently modified or deleted? Especially relevant for regulated industries.

from mem0 import Memory
import asqav

asqav.init(api_key="sk_...")
agent = asqav.Agent.create("mem0-auditor")
session = agent.start_session(name="memory-audit")

m = Memory()
result = m.add("User prefers conservative investment strategy", user_id="alice")

# Sign the memory operation - chained to previous
session.log("memory:add", metadata={
    "user_id": "alice",
    "memory_id": result["results"][0]["id"],
    "content_hash": asqav.hash_content("User prefers conservative investment strategy")
})

Each operation gets an ML-DSA-65 signature chained to the previous action. You can export the full trail and prove no memory was tampered with after the fact.

Useful for financial services, healthcare, or anything where you need to prove your agent memory layer was not modified between interactions.
