<td>E2E integration test + RTL fixes: mixer sequencing, USB data-pending flags, receiver toggle wiring</td>
<td>New 46-check E2E testbench (tb_system_e2e.v) across 12 groups. RTL fixes: TX/RX mixer enables mutually exclusive by FSM state, USB write FSM data_pending sticky flags with stream-control reset default 3'b001, STM32 toggle signal wiring for mode-00, dynamic frame detection. USB tests 21/22/56 and regression script PASS/FAIL parsing fixed. 19/19 FPGA, 20/20 MCU.</td>

<td>SHIFT state merged into WRITE for 5&rarr;4 cycle butterfly (20% throughput gain). Multiplier-based twiddle index replaced with barrel-shift (frees 1 DSP48). Verified via FFT testbench; no timing regression expected.</td>
