Which authorization component achieves the zero percent unsafe rate?
The paper reports that two authorization checks together prevent unsafe actions, but doesn't isolate which one—the token verification or the policy oracle—actually carries the result. This matters for understanding whether both are necessary or one is redundant.
The abstract lists "a component-level ablation of the authorization boundary" among the paper's contributions. The evaluation passage in the excerpt defines two conditions: "T0 disables the token check and policy oracle, whereas T1 enables both." That comparison isolates the layer, not its parts. It shows that the pair together takes memory poisoning from execution in every trial to 0 percent Unsafe Action Rate (Can memory poisoning compromise decision-making even with authorization layers?), and says nothing about either alone.
What a division might look like, as my reading. A signed task-bound token can say that this action was licensed for this task, which is a provenance question. A policy oracle can say that this action is permitted at all, which is a policy question. A forged approval could plausibly fail one and pass the other. Whether it does is exactly what the excerpt leaves out: the attack is described as a forged approval, and nothing says which check it fails.
Why it matters for use. If one component alone holds 0 percent, the other is redundancy or cost, and the cost side is unreported in the excerpt (FPR, LTC and F1 are named and given no values). If neither alone holds it, the pair is the boundary and the design cannot be simplified. The answer also bears on How does the authorization layer stay outside the poisoned path?, since the component that carries the result is the one whose isolation has to be argued.
What would move the answer. The single-component conditions, if the full paper reports them, or Table I broken out by component. Failing that, the paper's own ablation section named in the abstract.

Can memory poisoning compromise decision-making even with authorization layers?
When authorization systems add signed tokens and policy oracles to an AI pipeline, does this stop attackers from poisoning the agent's judgment about whether to approve actions, and what actually prevents unsafe execution?

How does the authorization layer stay outside the poisoned path?
The containment result depends on task-bound tokens and a policy oracle remaining unreachable by memory poisoning attacks. The excerpt names these defenses but provides no design details about token issuance, binding scope, verification procedure, or whether tested attacks actually targeted them.

Do authorization rules or restricted tools prevent test modifications?
The abstract reports that an explicit-boundary regime prevents protected test changes, but combines clear rules with restricted tools. This note explores which factor—or both—actually keeps tests unmodified, since the two mechanisms work differently on agent behavior.
