Per Codex review of dd7ca4f (testbench only, RTL unchanged):
1. Stall check now requires d_wvalid to REMAIN asserted (catches a deassert) and
compares the COMPLETE {d_wdata,d_wstrb,d_wlast} against the held beat, not just
d_wdata.
2. Added saw_full_and_ready coverage flag (set on dut.full && d_wready) and a final
check that FAILS if the distinguishing no-bypass case was never observed.
No RTL change, no simulations, no Quartus.

sim/tb — Testbenches
Per-subsystem SystemVerilog / Verilog testbenches.
Planned layout (created as each subsystem lands its first stub):
tb/memory/— memory map and arbitration tests.tb/dmac/— EE DMAC channel tests.tb/gif_gs/— GIF packet intake and GS register decode tests.tb/sif/— EE<->IOP mailbox/DMA tests.tb/ee/— EE core directed tests.tb/iop/— IOP core and IOP-DMA directed tests.tb/vif_vu/— VIF unpack and VU microprogram tests.
Rule: no testbench directory is created until the matching subsystem has a
contract in docs/contracts/ and a stub in rtl/.
