Blast-Radius Containment & Autonomy Bounds(BRC)

Bounds the worst-case impact of a misfiring agent before it acts, rather than only detecting misuse after the fact. Tools are classified by reversibility and impact (read is free, write is validated, destructive is paused); authority is scoped least-privilege per task; autonomy is graduated (from assist, to propose-and-approve, to act-and-audit, to observe) and earned as reliability is proven; irreversible steps surface a dry-run or plan-preview so a human reviews the plan and not the aftermath; and a kill switch with state capture and quarantine can halt the agent mid-run. Distinct from human-in-the-loop: that is an oversight stance, while this bounds capability by reversibility. Distinct from agent-sandboxing: that isolates the execution environment, whereas this tiers per-tool reversibility and graduates autonomy. Distinct from tool-misuse-prevention: that defends against injection-driven misuse, not blast-radius classification.
