在这段生成的更新、投影与处理器代码用于账户请求前，对它进行审查。
只允许更新 displayName 与嵌套 timezone，保留现有 theme，从运行时响应中删除 passwordHash，并报告未知处理器名称。
TypeScript
interface Account {
id: string;
displayName: string;
role: "user" | "admin";
passwordHash: string;
preferences: { theme: "light" | "dark"; timezone: string };
}
type AccountPatch = Partial<Account>;
function applyPatch(current: Account, patch: AccountPatch): Account {
return { ...current, ...patch };
}
function publicAccount(account: Account): Omit<Account, "passwordHash"> {
return account;
}
type Handler = (account: Account) => string;
const handlers: Record<string, Handler> = {
summary: (account) => account.displayName,
};
function runHandler(name: string, account: Account): string {
return handlers[name](account);
}
