That reflects the emulator, not the image - in the same job the Browser Host starts, migrations run and the framed health ping on its socket succeeds, so only the exec of chromium fails. Teach browser-smoke.mjs the SMOKE_SKIP_CHROMIUM_LAUNCH escape hatch: when set to "true" it asserts the shipped /usr/bin/chromium binary is present and executable instead of launching it. containers.yml sets it only for the arm64 matrix cell on an X64 runner, so native arm64 runners would still launch Chromium for real.
