# Container Snapshot

This folder contains a snapshot of the current Codex environment.

## Included:
- SYSTEM_INFO.md – Kernel and OS info
- ENV_VARS.md – All environment variables
- FILESYSTEM_TREE.md – Hierarchical view of the workspace
- Codebase – All source files from /workspace

## Purpose:
This snapshot can be reused to recreate the current environment, build new features (like offline .NET SDK), or run isolated analysis outside the sandbox.
