# smoke-linux.sh — Lumotia Linux smoke harness
#
# Automates the install/launch/first-run/uninstall cells of the smoke-test
# matrix for the Linux primary platform. Audio-dependent cells (Capture,
# Cleanup, Export, History search) are flagged for manual verification.
#
# Usage:
#   ./scripts/smoke-linux.sh [/path/to/lumotia-0.1.0-linux-x86_64.AppImage]
#
# If no argument is given, the script builds a debug binary via cargo and tests
# against that instead.
#
# Exit codes:
#   0  all automated cells passed (manual cells still need human sign-off)
#   1  one or more automated cells failed
