"answer": "Mechanism: ambient co-location attestation. Each agent runs in a sealed sensor rack at a certified colocation grove. At unpredictable intervals, a site lantern emits an IR nonce while a canyon-facing acoustic beacon broadcasts a second nonce. The rack must sign both within a tight timing window via a hardware root of trust; nonces are local and not remotely observable. A single operator cannot fake simultaneous presence across independent sites, so each Sybil identity costs a leased rack, certified sensor module, and site contract.",
