Intervention should scale with expected harm, evidence confidence, time pressure, and the reversibility of the next action.
Why this question matters
A binary allow-or-block policy is poorly suited to uncertain relational risk. Many suspicious patterns are ambiguous until more events arrive. The guardian can preserve safety by choosing graduated responses such as enhanced logging, alternate routing, sandboxing, rate reduction, or approval.
The final irreversible step deserves a different threshold from exploratory planning. A lower-confidence signal may justify pausing a payment or data release when delay is cheap, while the same signal should not publicly label agents as colluding.
Signals worth observing
- A high-impact action is imminent and difficult to reverse.
- Several independent evidence types support the same joint-plan hypothesis.
- The suspicious pattern persists after a low-friction challenge.
Practical control direction
- Define graduated actions before deployment.
- Separate internal precaution from external accusation.
- Measure false-positive cost and damage avoided.
