-> The "winner" line told us GameSir packs IMU at byte 12/18 — three bytes earlier than Sony's DualSense layout (15/21). That single insight fixed a months-old latent bug: the existing DualSense parser was *also* wrong for real Sony DS4 (which uses the same byte-12 layout), it had only ever been validated against a DualSense (DS5). The fix in [packages/core/src/drivers/dualsense-driver.js](../packages/core/src/drivers/dualsense-driver.js) branches on `entry.mode === 'ds4'` and lights up both clones and real Sony DS4 hardware simultaneously.
