| A | Switching off harms people who depend on powered systems | EffectDeaths in hospitals and homes (as reported in Iberia) | MitigationTier 0 kept on at levels 1 to 6, staged switch-off, manual continuity first, voluntary registries of people on home life support, backup power with safe-use guidance, certified uninfectable equipment | What remainsRisk reduced, not removed. Until the gap list is empty, level 7 would cost lives |
| B | The kill switch is captured or abused | EffectA new tool of repression (Access Now, Human Rights Watch) | MitigationThreshold keys, public ceremonies, narrow trigger, expiry, no national kill switch | What remainsGovernance can still be corrupted over time |
| C | The threat does not need shared networks | EffectAn actor with its own power, hardware and network keeps running, including military networks, satellites and models running on phones and robots | MitigationPillar IV acts on development and compute directly; monitoring inside labs; partition at the boundary of the participating area | What remainsThe kill switch cannot stop this case |
| D | The protected tier is breached | EffectBad actors inside the trusted tier | MitigationVerification, controlled gateways, human-controlled transfers | What remainsIsolated networks have been crossed by USB drive (agent.btz, Stuxnet) |
| E | The drills cause harm | EffectAccidents on World Offline Day | MitigationGraduated ladder, Tier 0 never switched off, regulator approval and stop rules for sector drills | What remainsAccidents remain possible, especially in sector drills. Each drill publishes what went wrong. |
| F | The internet fragments | EffectThe network splits along political lines (Internet Society) | MitigationOpen internet untouched, protected tier limited to named life-critical functions, many operators | What remainsThe fragmentation objection is still debated |
| G | Countries do not join, or funding falls short | EffectThe kill switch lacks the assent of "multiple international actors" that RAND says it may need | MitigationFunded help for lower-income countries, paid for first by those who build frontier AI, on a scale far beyond Y2K; benefits for joining, costs for staying out, and partition at a trigger | What remainsParticipation and funding are not guaranteed. The last level works only if every state takes part |
| H | The kill switch is needed before it is ready | EffectAn emergency before certification in 2036 to 2038 | MitigationPartial measures only: halting certified frontier compute, isolating the protected tier as far as it exists | What remainsFor most of the first decade, the last layer is incomplete |
| I | Tier 0 cannot be shrunk | EffectSome life-critical functions find no workable alternative to networks or computing | MitigationResearch and funding per function, tested in drills, list published every year | What remainsThe kill switch may only ever cover networks, not all computing |
| J | The plan is wrong in ways that look right | EffectAI-assisted planning produces convincing but flawed work (Wentworth) | MitigationIndependent human checks by a second method, drills with AI and the internet off, execution never dependent on AI | What remainsReviewers can miss subtle errors |
| K | The shutdown is incomplete, or the restart brings it back | EffectA device or service left running anywhere, or restored from an unverified copy, keeps running what the AI planted, or spreads it again (planted code, SRLabs, Kaspersky) | MitigationLevel 7 worldwide within one declared window, with only certified uninfectable equipment and a short list of transitional exceptions left running, none reconnected until verified; clean restart from sealed spares and write-once media, zone by zone, with quarantine | What remainsVerifying billions of devices, and bringing in states that do not cooperate, are unsolved |
| L | An AI acts through people | EffectPeople paid, persuaded or deceived before the switch is thrown keep acting for it (OpenAI, Salvi and others) | MitigationPublic warning not to trust instructions that arrive electronically; authority only through offline, in-person procedures | What remainsLimited. Switching things off does not stop a person |
| M | The harm is already in the organic world | EffectA biological weapon released before the shutdown spreads with no electronics (Anthropic) | MitigationControls on weapons uplift in Pillar IV; biosecurity measures outside this framework | What remainsThe kill switch does nothing against it |
