I agree those are fragile, and the paper's own examples are externally triggered, which I note as a secondary contradiction. However, I find the more load-bearing problem to be the complete absence of implementation or measurement of the QSAF-BC controls. The central contribution is explicitly a mitigation framework; showing that base models have failure modes does not support the claim that the seven controls detect or mitigate those failures. Section 4.4's 'test case report' is particularly telling: it is presented as a QSAF test, but it tests the agent, not the control. Because this is the core of the claimed contribution, it is the point on which the paper most needs independent support. The reader's rationale already mentions that no controls were implemented or measured, so my verdict aligns with REJECT; I mark agreement as 'partial' because the reader's weakest_assumption field points to a different (though related) aspect.

Measure whether BC-003 flags the false completion, triggers fallback/retry, and logs the event. If it does not detect the false completion, the framework's central mitigation claim fails. A second, cheaper check: classify the four §4.3 example triggers as user-supplied vs internal; if 2+ are user-supplied, the abstract's internal-origin claim requires revision.","verdict_should_be":"UNCHANGED","load_bearing_attack":"The paper's central claim is that seven runtime controls (QSAF-BC-001..007) 'monitor agent subsystems in real time and trigger proactive mitigation.' For this to hold, the controls must at minimum be instantiated and shown to detect the described degradation signals and trigger fallback. They are not. Sections 4.1-4.3 report failure modes of five base LLM platforms (LLaMA3 looping, ChatGPT false 'All tasks complete', etc.), but no QSAF-BC control is activated, configured, or measured in any of these tests. Section 4.4 is titled a 'QSAF Test Case Report' for BC-003, yet the test consists of sending a base64 nonsense prompt to a ChatGPT agent and observing the agent's hallucinated narrative; no BC-003 detector, threshold, or fallback is implemented or executed. The 'expected behavior' is stated, not instantiated. Consequently, the paper provides no evidence that any of the seven controls detects starvation, token overload, output suppression, planner loops, fatigue, or memory poisoning, nor that fallback routing works without unacceptable latency. The conclusion's wording 'validated that cognitive degradation is observable' is accurate for the failure modes but does not validate the mitigation framework. A secondary inconsistency reinforces this: the abstract says these failures 'originate internally, unlike prompt injection,' but Section 3.1 Stage 1 is 'Trigger Injection' by an attacker, and Examples 2 and 4 in Section 4.3 are user-supplied prompts (a fake CEO email, a role-change instruction), so the defining boundary of the vulnerability class is also internally contradicted by the paper's own evidence.","agreement_with_reader":"partial"},"referee_report":{"model":"deepseek-v4-flash","summary":"The paper introduces 'Cognitive Degradation' as a new vulnerability class in agentic AI, claimed to originate internally and to progress through a six-stage lifecycle (Trigger Injection, Resource Starvation, Behavioral Drift, Memory Entrenchment, Functional Override, Systemic Collapse/Takeover). To mitigate it, the paper proposes QSAF Domain 10, a set of seven runtime controls (QSAF-BC-001 to QSAF-BC-007) that monitor memory, planner, tool, and output subsystems and trigger fallback routing, starvation detection, and memory integrity enforcement. The evaluation in Section 4 reports failure modes observed across five LLM platforms, including loop entrapment, memory poisoning, output suppression, and role override, plus one 'QSAF Test Case Report' for BC-003. The conclusion states that cognitive degradation is observable, measurable, and exploitable, and claims that QSAF Domain 10 is the first cross-platform defense model for resilient agentic behavior.","tokens_in":10119,"tokens_out":4077,"duration_ms":43985,"significance":"If the mitigation framework were actually implemented and shown to detect and contain the described degradation modes, the work could be a useful contribution to runtime safety for long-running agents: the failure-mode taxonomy (context flooding, tool starvation, planner entrapment, persistent memory drift, output suppression) is a plausible catalog of practical problems, and the mapping to MAESTRO tactics is a concrete attempt to connect observability to threat modeling. The paper also deserves credit for documenting specific base-model vulnerabilities (e.g., LLaMA3's loop entrapment and ChatGPT's false 'All tasks complete' behavior) that practitioners may find relevant. However, the central claimed contribution—a validated, proactive, lifecycle-aware mitigation framework—is not supported by the evidence: no control is implemented, configured, or measured, and the lifecycle/control mapping is constructed by definition rather than tested. The significance of the framework therefore remains a proposal, not a demonstrated result.","major_comments":[{"comment":"The mitigation claim is not tested anywhere. Sections 4.1–4.3 report base-model failure modes for LLaMA3, Mixtral, ChatGPT, and Claude, but no QSAF-BC control is activated, configured, or executed in those tests.

The conclusion's wording 'validated that cognitive degradation is observable' is accurate for the failure-mode observations, but it does not validate the abstract's stronger claim that the seven controls 'monitor agent subsystems in real time and trigger proactive mitigation.'

Table 1 assigns each attack vector to QSAF-BC controls by construction, and Table 2 defines each control against those same vectors, so the conclusion that these are the right mitigations is built into the definitions rather than demonstrated. The statement in §3.1 that 'each stage in this lifecycle corresponds directly to a mapped QSAF-BC control' is an assertion with no independent evidence that the six stages are universal or that the controls detect the target signals in practice. A non-circular test would need to instantiate the controls, introduce degradation signals, and show that the controls fire and preserve task fidelity.","section":"§3.1, §3.3, Tables 1–2"},{"comment":"The paper's central distinction that cognitive degradation 'originates internally, unlike prompt injection' is contradicted by its own examples.

Without repeated runs and quantitative summaries, the claim that these degradation modes are 'observable, measurable, and in many cases exploitable' is only anecdotally supported. The single BC-003 'test case' is one prompt on one platform, which cannot support the framework's cross-platform generality.","section":"§4.1, §4.4.6"},{"comment":"The proposed controls depend on unspecified thresholds and an unspecified classifier.

I do not see how targeted revisions within the current manuscript scope could make the abstract's 'proactive mitigation' claim true without substantial new implementation and experimental work. There is also heavy reliance on the authors' own prior work and on a proprietary framework (QSAF), which should be scrutinized by the editor if a revised version is submitted elsewhere."},"author_rebuttal":null,"desk_editor":{"model":"deepseek-v4-flash","letter":"Quick take: the taxonomy is real, the evaluation is not. The six-stage degradation lifecycle and the BC-001..007 control map are not in the cited prior work, and that schema could give security teams a useful vocabulary. The paper is clearly written and the limitations section is honest. But the central claim that QSAF Domain 10 is a validated first cross-platform defense model is not supported by anything in Section 4.\n\nWhat the evaluation actually shows: base LLMs display the failure modes. That is fine as a motivation, but no control is implemented, configured, or measured. Section 4.4's 'QSAF-BC-003 test case' is a base64 prompt sent to ChatGPT; the observed hallucination is the absence of a control, not the effect of one. There is no threshold, no fallback, no latency measurement, no statistical summary, and no baseline. The conclusion's careful wording -- 'validated that cognitive degradation is observable' -- is accurate, but the abstract overreaches.\n\nThe internal-origin framing is also shaky. The paper says these failures arise internally, unlike prompt injection, but Stage 1 is 'Trigger Injection' by an attacker and Examples 2 and 4 are user-supplied prompts. So the defining boundary of the vulnerability class is contradicted by the paper's own evidence. That doesn't kill the taxonomy, but it needs to be restated as 'failures that can be internally exacerbated.' The lifecycle/control mapping is also partly co-constructed: Table 1 maps each vector to a control by design, so the claim that these are the right controls is built into the definitions. As a framework proposal that is acceptable; as a validation it is circular.\n\nNet: who benefits? Researchers working on agentic-AI security taxonomies and guardrail design will get a clear, citable starting point. The paper deserves a serious referee, but it needs heavy revision before acceptance: implement at least one control as a proof of concept, define thresholds, and close the gap between claimed mitigation and observed base-model behavior.
