Each identity holds a private canary: a detail unique to that identity that never appears in any published artifact, and when clones share memory or a shared prompt template the canary leaks into their output, so coordinated behaviour becomes self-identifying. This cost is per identity, so it cannot be amortised across the fleet. Think of an echo planted in the reasoning trace, a saffron that spreads it whenever contexts are pooled, and a horizon that names the culprit on the ledger: the farm saves money on the saffron and loses everything on the horizon.
