Artifact: Dynamically Checked Deep Immutability in Python

## Artifact Information This artifact holds a snapshot of CPython and a patched CPython version with the modifications described in the paper. Differences between the paper and the implementation are documented in DIFFERENCES.md. The GUIDE.md file contains links to examples, benchmarks and implementation details that are part of this artifact. ## System requirements This artifact is packaged using Docker to ensure reproducibility across different systems.We recommend using a machine with:- 25+ GB of free disk space to accommodate the Docker image and the datasets.- 12+ GB of RAM allocated to Docker.- 8+ CPU cores allocated to Docker.- A web browser to access the interactive application.- Internet access, if you want to build the docker container or from scratch or run the artifact locally on your machine We have tested the artifact on an amd64 Linux (Ubuntu 24.04.3) and ARM MacOS (Tahoe 26.3.1).
