- rootfs/sbin/init: the control bridge answers `@cat PATH` locally so the
driver can read /tmp/warden-web-status.json out of the guest. That file
has no trailing newline; the bridge adds one so the sentinel stays on
its own line and the line-based reader never blocks.
- tests/qmp.py: wait_json/assert_json (dotted paths, eq/ne/contains/
len_eq/len_ge/gt/lt), assert_stat off the FIFO's stats reply,
capture_region, assert_region NAME [TOLERANCE] and assert_ocr. A
tolerance other than the captured one, a reference box that does not
fit the screendump, a missing reference or a missing tesseract is FATAL
for that step and the run continues (flare-edge #147).
- tests/imgtools.py: P6 reader, crop, perceptual and structural hashes,
compare, with a self-test.
- tests/test_qmp_drive.py: drive() with QMP and the control channel
faked, pinning the per-step ok/fail/fatal contract.
- mkimage.sh SEED_DIR and ui-drive.sh --seed/--refs: settings fixtures
staged into userdata before warden-ui starts, and a reference store
handed to the driver.
- ci: the driver tests and the imgtools self-test run in qemu-tools.
