about
_k_r2_001a_gate.nx -- the K-R2-001a gate (virtio-MMIO transport HANDSHAKE). Drives the
full author->handshake chain with NO mocks: runs the REAL nx_virtio_hs_emit (the team
AUTHORS the rv64 handshake image + the TABLE-COMPUTED golden transcript from the spec),
then RUNS the image on the SOVEREIGN rv64 emulator (rv64im_min_sim with the new
rv64im_min_virtio device carved into load32/store32 -- the PRIMARY, gating lane: Nishi
owns the runtime) and asserts the captured serial transcript CONTAINS the emitter's
golden ("VIO ACK DRV FEAT OK\n" -- the driver verified magic/version/device-id, drove
Status through ACK/DRIVER/FEATURES_OK/DRIVER_OK, read HostFeatures, wrote GuestFeatures,
re-read Status to confirm FEATURES_OK stuck) AND the sovereign emu reports a clean
SiFive-finisher halt (BOOTSOV verdict=GREEN).
Then the ALIGNMENT lane: qemu-system-riscv64 -machine virt -global
virtio-mmio.force-legacy=true with a REAL virtio-blk-device backing. qemu fills its
virtio-mmio slots in REVERSE (the blk device lands at the highest slot 0x10008000, not
the spec's sovereign base 0x10001000), so the gate authors a SECOND image from a derived
spec whose base = the qemu blk slot and runs THAT on qemu; the SAME handshake driver
completes against the REAL legacy virtio-blk transport and emits the SAME golden
transcript -> lanes AGREE on the handshake (alignment = handshake-completes-on-real-hw,
transcript-identical).
Finally a TAMPER test: corrupt the magic-expected constant in the sovereign image -> the
driver's magic verify fails -> it branches PAST the whole handshake straight to the
finisher -> the transcript loses its golden -> the gate MUST go RED (proves the gate
bites, not a rubber stamp). Evidence -> knowledge/status/virtio_blk.log (VIRTGATE row;
the queue row's ||MARK= reads it). Sovereign orchestration (fork/dup3/execve/wait4).
