about

_boot_stub_gate.nx -- the K-R0 gate (kernel-up ladder rung 0). Drives the full author->boot chain with NO mocks: runs the REAL nx_boot_stub_emit (the team authors the stub from the spec), then runs the REAL qemu-system-riscv64 -machine virt (the declared hardware-oracle lane, per the ladder), captures the serial output, and asserts the K-R0 acceptance: banner "NISHI" on serial + clean exit (qemu status 0, the SiFive finisher pass). Evidence -> knowledge/status/boot_stub.log (BOOTGATE row, the row's ||MARK= reads it). Sovereign orchestration (fork/dup3/execve/wait4). NOTE: the emitted stub ALWAYS writes the finisher, so qemu self-exits; no watchdog needed for our own artifact (a watchdog is a hardening follow-up if arbitrary stubs are ever gated). license_tier: ORIGINAL
