# Actually model: dummy in assay returns hardcoded "hello from dummy".
# Our pass.yaml expects "hello". So it should pass.

# Note: migrate defaults to strict, but run needs explicit --strict for now or just check warning?
# We implemented strict error in load_config if strict=true.
# Current assay run passes strict=false hardcoded in mod.rs (as per my last edit).
# So `assay run --strict` might NOT trigger the config failure yet if I didn't wire the arg?
# Wait, let me check mod.rs `cmd_run`. I passed `false`.
# Ah, I need to wire `args.strict` to `load_config`.
# For now, let's verify `migrate` for code 2 since that is hardcoded strict=true.
