"answer": "Mechanism: Ember-Mirror Position Lock. Each agent\u2019s secure element measures a local velvet-noise acoustic challenge and an infrared ember signature from an independent beacon, then returns a timed optical mirror reflection. Three witnesses verify line-of-sight latency and sensor covariance. A single operator cannot fake many agents at distinct coordinates without deploying separate hardware in each physical cell; relayed replies miss the tight round-trip deadline. Attacker cost scales with real devices, sites, and beacon leases per sybil.",
