“Self-state attacks” are described as attacks that corrupt an AI agent’s persistent memory, instructions, or configuration through otherwise legitimate interactions, potentially influencing later behavior. The supplied research snippets establish active work on memory-poisoning attacks and defenses for memory-based LLM agents, including reliability-conditioned updates, provenance caps, and protections against poisoned retrieved content. However, the snippets do not establish attack reliability, practical defense effectiveness, or Schmidhuber’s role in this work; those points require follow-up research.

Repeated checks have produced only anecdotes and unevaluated integrity projects, with no controlled attack replication or comparative defense results. The episode has exhausted its near-term evidence horizon and should be reopened if primary measurements or an independently validated mitigation appear.
2026-08-13T20:31:56Z
The new anecdote suggests at least one deployed assistant can recognize and reject instruction-like content embedded in memory data, adding weak evidence that trust-boundary defenses are reaching products. It is not reproducible and provides no attack-success, downstream-harm, or defense-effectiveness measurement, so the core research question remains dormant.
2026-08-13T20:23:16Z
evidence attached: reddit.post.1vnl89z — This anecdotal report describes instruction-like content appearing around persistent memory and is relevant contextual evidence for memory poisoning and integrity defenses, though it is not a reproduction.
2026-08-13T05:27:13Z
The refreshed comments remain skeptical reaction and general discussion, adding no reproducible attack, downstream-harm measurement, or independent defense evaluation. The case is still a dormant research question despite continued activity around agent-memory integrity.
2026-08-13T04:23:48Z
The refreshed discussion remains skeptical reaction and implementation questions rather than evidence about the protocol or self-state attacks. It adds no controlled replication, downstream-harm measurement, or independent defense evaluation, so the case’s meaning is unchanged.
2026-08-13T03:36:29Z
Refreshed comments are largely skeptical or ask basic implementation questions; they add no primary attack results, protocol validation, or independent evaluation. The case remains a dormant research question despite broad interest in agent-memory integrity.
2026-08-13T02:31:46Z
The new package adds a signed append-only memory protocol and a claim that agents found attacks against its verification, but both come from the same promotional source without primary attack results or independent evaluation; the attached HN item also appears unrelated. This broadens the defense landscape without establishing poisoning reliability or practical mitigation effectiveness.
2026-08-13T02:22:28Z
evidence attached: hn.story.49281006 — The post provides additional evidence about the same agent-memory integrity protocol and reported attacks against it.
2026-08-13T02:22:28Z
evidence attached: reddit.post.1vmxrxl — The report describes a deployed agent-memory protocol and claims independent agents found attacks against its verification mechanism.
2026-08-13T02:22:28Z
evidence attached: reddit.post.1vmx06a — The proposed signed append-only memory protocol is a concrete integrity defense against persistent-agent memory tampering.
2026-08-12T04:30:24Z
Refreshed comments only describe manual deletion, disabling automatic writes, and prompt-level consent as user workarounds; they neither demonstrate self-state attacks nor evaluate integrity defenses. The case remains a dormant, high-relevance research question awaiting controlled attack replication and comparative mitigation results.
2026-08-11T15:03:15Z
The new provenance-oriented project reinforces versioning and blame as a practical memory-integrity pattern, but provides no technical detail, attack replication, or evaluated defense result. It broadens the implementation landscape without advancing the core poisoning-reliability or mitigation-effectiveness questions.
2026-08-11T14:28:21Z
evidence attached: hn.story.49258591 — Versioned blame and provenance for agent memory materially informs defenses against poisoned or corrupted persistent state.
2026-08-11T07:47:16Z
The new stale-memory example adds temporal validity and lifecycle handling to the mitigation space, but remains an anecdotal workflow claim rather than an attack demonstration or evaluated defense. The core questions of poisoning reliability, downstream harm, and practical integrity-control effectiveness remain unchanged.
2026-08-11T07:22:37Z
evidence attached: reddit.post.1vl9nxe — The stale-memory failure mode and audit tool materially contextualize practical integrity risks in persistent agent state, though they are not an independent attack demonstration.
2026-08-10T20:33:40Z
The deployed-assistant anecdote adds a concrete symptom of overbroad persistent-memory writes, modestly increasing practical salience but not identifying an attack or downstream harm. It does not advance the core questions of self-state poisoning reliability or defense effectiveness.
2026-08-10T20:22:31Z
evidence attached: reddit.post.1vkuwz3 — Reports an unintended persistent-memory write, providing a concrete example of memory-integrity and user-control problems in deployed assistants.
2026-08-09T19:43:48Z
The staleness trigger adds no attack replication, downstream-harm measurement, or comparative defense evaluation; existing projects remain unevaluated design responses rather than validation. The case is still consequential to persistent-agent architecture but has not advanced beyond a dormant research question.
2026-08-07T19:36:42Z
The staleness check adds only minor engagement changes and no controlled attack replication, downstream-harm measurement, or comparative defense evaluation. Multiple integrity-oriented implementations keep the question relevant, but the core hypothesis remains dormant and unsettled.
2026-08-05T11:27:56Z
The newly attached cryptographically auditable-memory project overlaps an already assessed implementation from the same author and adds no independent attack replication or defense evaluation. The case remains dormant pending controlled measurements of poisoning reliability and mitigation effectiveness.

2026-08-04T17:27:38Z
The trigger adds no identifiable substantive evidence beyond already assessed project claims and anecdotes; the only engagement reobservation is unchanged. The case remains dormant pending controlled attack replication or comparative defense measurements.
2026-08-04T13:24:52Z
The latest check yields no substantive new evidence: repeated project claims and anecdotes still do not replicate self-state attacks or evaluate defenses. The case remains consequential to Scott but dormant pending controlled attack and mitigation measurements.
2026-08-04T12:27:12Z
The latest trigger adds no substantive evidence beyond previously assessed anecdotes and unevaluated integrity projects. The case remains a dormant but consequential research question awaiting attack replication or comparative defense measurements.
2026-08-04T11:27:25Z
The anecdotal report shows user-visible false facts can persist in a deployed assistant, but it does not identify self-state poisoning, establish provenance, or measure downstream harm. It adds a weak symptom-level observation rather than corroborating the attack mechanism or evaluating defenses.
2026-08-04T11:21:34Z
evidence attached: reddit.post.1vf730a — Anecdotal reports of persistent agents inventing personal facts bear on memory integrity, though this is not independent corroboration.
2026-08-04T06:23:22Z
The delayed-failure framing broadens the threat model from bad writes to latent corruption surfacing downstream, but the evidence is only an unsupported project-level claim. It adds no attack replication or defense measurements, so the core reliability and mitigation questions remain unsettled.
2026-08-04T06:21:16Z
evidence attached: hn.story.49164643 — The delayed-failure framing materially supports the case that persistent agent-memory corruption can surface later rather than immediately.
2026-08-03T13:22:40Z
The new project adds another independent design response—retaining poisoned memory for audit rather than silently deleting it—but supplies no attack replication or defense evaluation. It broadens the mitigation space without settling whether self-state poisoning is reliable or whether practical integrity controls prevent downstream harm.
2026-08-03T13:21:33Z
evidence attached: hn.story.49155409 — The project directly bears on whether poisoned data persists in agent memory, providing independent contextual evidence for the open memory-integrity case.
2026-08-03T02:25:25Z
The latest changes are minor amplification with no attack replication, defense evaluation, or comparative measurements. The case remains an important but dormant research question, and existing implementation claims do not settle poisoning reliability or mitigation effectiveness.
2026-07-31T01:21:47Z
The latest check adds only negligible amplification and no attack replication, defense evaluation, or comparative measurement. Multiple integrity-oriented projects keep the question relevant, but the core reliability and mitigation claims remain dormant and unsettled.
2026-07-28T16:25:22Z
A third independent implementation reinforces design convergence around signed, auditable, integrity-protected agent memory, but remains an unevaluated project claim. The case still lacks attack replication or comparative defense measurements, so it does not yet corroborate reliable poisoning or practical mitigation effectiveness.
2026-07-28T16:21:40Z
evidence attached: hn.story.49085672 — Signed, independently verifiable shared memory is directly relevant as a potential integrity defense against poisoned persistent agent state.
2026-07-28T12:25:24Z
A second independent implementation suggests growing design convergence around auditable, integrity-protected agent state, but it is only a project claim and does not test self-state attack reliability or mitigation effectiveness. The case remains a consequential but dormant research question rather than substantive corroboration of the core hypothesis.
2026-07-28T12:21:42Z
evidence attached: hn.story.49082711 — A database-native audit and state engine is a potentially relevant integrity defense for persistent agent state, though currently only a project claim.
2026-07-27T23:21:38Z
No new attack measurements, defense evaluations, or independent replication have appeared; the slight engagement increase adds no substantive corroboration. The case remains relevant but dormant while awaiting evidence on real-world poisoning reliability and mitigation effectiveness.
2026-07-22T16:23:38Z
An independent memory-integrity implementation shows the threat model is prompting practical defenses, moving the case beyond a paper-only seed. It still provides no measurements establishing reliable self-state poisoning or effective mitigation, so the core hypothesis remains unsettled.
2026-07-22T16:22:39Z
evidence attached: hn.story.49008522 — Veracium is a concrete memory-integrity defense against untrusted claims becoming persistent agent facts, materially contextualising the open self-state-poisoning case.
