Use embedded_launcher: true in python tools These scripts generate files, and they include the command used to generate them in the file itself. When using a non-embedded-launcher python binary, the binary is a zip file that extracts itself to a temporary folder before running. The temporary folder is non-deterministic, and that non-deterministic path will end up in the file since they write the sys.argv to the file. embedded_launcher binaries do not extract the zip, and thus don't have any non-deterministic paths.

PDL is a domain specific language for writing the definition of binary protocol packets. Parsing and validating packets from raw bytes is tedious and error prone in any language. PDL generates memory safe and tailored backends for multiple target languages:
- Rust - C++ - Python
Historically PDL was developed as part of the Android Bluetooth stack (bluetooth_packetgen) as a way to generate the parser and serializer for Bluetooth packets, and reduce the number of memory safety issues that come with manipulating and validating raw data.
