Render cache and the cost ledger
User-scoped render cache keys, classification events, and billable-cent tracking. How we stop regenerating on every page load.
Tomas Laurinavicius
Renders cost real model credits. The cache key scopes by pattern, brand, prompt version, content fingerprint, and user so a refresh never quietly re-bills.
The ledger is the accountability layer. Every successful path logs classification and cost estimate so smoke can run fake and production stays auditable.
