Repro Code

export const marker = "marker" as const;
export interface Data {
  marker: typeof marker;
  value: string;
}
function createData(): Data {
  const base = { marker: marker };
  return { ...base, value: "" };
}

ESLint Config

module.exports = {
  "rules": {
    "@typescript-eslint/no-unnecessary-type-assertion": "error"
  }
}

tsconfig

{
}

Expected Result

The first line of this code should not report an error for the as const assertion, since this assertion is necessary - removing it is a TypeScript compilation error (see TypeScript playground).

Actual Result

Starting in typescript-eslint@7.3 (presumably #8558), the first line of this code reports a @typescript-eslint/no-unnecessary-type-assertion error.
