v33 milestone: first M->S application data crossing on silicon (2026-06-10). Bitstream built from e2fefd4 + the deskew pipeline (c5f24b6) and run with the M12 bootstrap (7702f07); this tag points at the first commit whose tree matches what was on the boards. Result: bilateral 16/16 cal+lock, FCSM=4 bilateral, 4-pkt AHB_TX burst landed byte-perfect in the slave RX FIFO (hdr=0x00240000 p0=0xDA7A0000). Master tap16 / slave tap7. Known residual: S->M credit decode intermittent (~97%, marginal eye) — superseded by the new PHY.
