…user/agent The current `validateNoSetStateInEffects` error has potential false positives because we cannot fully statically detect patterns where calling setState in an effect is actually valid. This flag `enableVerboseNoSetStateInEffect` adds a verbose error mode that presents multiple possible use-cases, allowing an agent to reason about which fix is appropriate before acting: 1. Non-local derived data - suggests restructuring state ownership 2. Derived event pattern - suggests requesting an event callback from parent 3. Force update / external sync - suggests using `useSyncExternalStore` This gives agents the context needed to make informed decisions rather than blindly applying a fix that may not be correct for the specific situation.
