Description

// AB.ts
export type A = {};
export type B = {};

// ABFeature.ts
export type * as AB from "./AB.ts";

// foo.ts
export type A = {};

// index.ts
export * from "ABFeature.ts"; // Error: duplicate identifier `A`
export * from "foo.ts";       // Error: duplicate identifier `A`

There are no duplicate identifiers. Symbol A can't be accessed through ABFeature.ts, and can only be accessed as AB.A.

Contributor guide

Research direction
Inspect the rule responsible for reporting duplicate identifiers (likely the 'no duplicate imports' or similar rule) and update its logic to correctly handle namespaced re exports, ensuring that identifiers within a namespace are not flagged as duplicates of top level exports.
