THEN Explicitly set the `layer_types` list in `Qwen3Config` to match the code logic: layers with index >= `max_window_layers` use `"sliding_attention"`, lower layers use `"full_attention"`. Do not rely on the auto-generated list from the documentation comment, as it is reversed.

from transformers import Qwen3Config
config = Qwen3Config(
    num_hidden_layers=24,
    max_window_layers=12,
    sliding_window=4096
)
# Manually assign top layers as sliding_attention
config.layer_types = [
    "full_attention" if i < config.max_window_layers else "sliding_attention"
    for i in range(config.num_hidden_layers)
]
