"""Tests for the new-version triage workflow (harness/triage.py, docs/40).
The orchestration tests use injected fake step runners: no QEMU, no native
boot, no firmware. The integration test uses the real TU104 570.144 fwimage
read-only with a tiny budget and skips cleanly when it (or
qemu-system-riscv64) is absent. Everything is bounded and touches no
hardware, GPU, module, guest or network.
Run::
python3 -m unittest tests.test_triage -v
