tilelang.analysis.parallel_local_index_checker.ParallelLocalIndexChecker()

Reject indexing a thread-private local buffer with a T.Parallel loop variable.

Local buffers have no cross-thread ownership layout. A local access may appear inside a parallel loop when its index is independent of the parallel loop variables, for example a replicated scalar scale_local[0]. For an indexed per-thread loop, use T.serial, T.vectorized, or T.unroll; for distributed ownership, allocate a fragment instead.
