Research direction

The launcher in serve/server.py builds the engine command in engine_args(cfg), called from main() where StrataEngine is constructed, and the error is raised in StrataEngine.init. The engine's own usage text lists --reserve-mib, not --vram-reserve-mib, so the mismatch is between the flag the launcher passes and the flag the binary accepts. Done when the settings file from the report starts the engine without the 'unknown option' exit, which means checking whether the launcher should send the name the engine accepts or the engine should accept the name the launcher sends.

Written by the indexing model from the issue text.
