Describe the bug When generating types for the rule, emits the same interface twice: TypeScript merges interfaces with the same name, but duplicate index signatures collide: The rule's JSON schema references a shape from two distinct subschemas ( and the inner replacements map). The emitter derives the same generated name () for both and writes a full declaration per occurrence instead of deduping by name. Interfaces with only non-index members would merge cleanly, but identical index signatures cannot. Reproduction System Info 2.3.1 64.0.0 TypeScript with Used Package Manager pnpm

Describe the bug When the option is set the generated code contains the following declaration: In ESLint 9.38.0 is now a type in place of an interface and thus can no longer be extended: https://github.com/eslint/eslint/blob/8fe511b4c0fb74df3290271b29c672c3fbf3be1f/lib/types/index.d.ts#L1328 If I'm getting it correctly the new proposed way to extend config type going forward is: As a side note has been changed too in ESLint 9.39.0. Although it still work as the type is essentially the same, it may be worth importing directly from the @eslint/core module.

Describe the bug are currently generated as typed keys, and this can cause conflicts with other properties if they have different value types. For example, Vitest's has the following type generated for it's options: This type is problematic, and gives the following errors in Typescript: This is similar to the issue faced in json-schema-to-typescript#671. This can be seen by running the typegen on 's rules.
