Transaction Simulation Story is useful before a signature only when the preview says exactly what it simulated. A dry run can show a result against selected state, but the preview should not pretend that result is the future block, the final ordering, or the user's full intent.
The mistake is easy to make in AI wallets and agent wallets. A transaction preview sounds like a single safety layer, while the actual evidence comes from different layers: Ethereum execution APIs, client debug methods, provider simulation APIs, ABI decoding, and wallet warning UX.
