info ~~warn~~ → info by review dynamic-execution CONTRIBUTING.md:134:1

[markup prose] pipeline feeds into `sh` — piped data is executed as shell code (ast pass, confidence 0.80)
```
$ curl https://sh.rustup.rs -sSf | sh
```
likely benign LLM, confidence 0.93 A markdown contributing guide shows the documented rustup installer command piped from curl to sh.
Reasoning
The finding is a standard rustup install instruction inside a markdown contributing guide. The curl-to-sh pattern is a common, documented installation method for the official Rust toolchain installer. It appears as prose in documentation, not as executable code in the project, so it is not a dropper or obfuscation. The pipe-to-shell pattern is widely discouraged for security reasons, but here it is a legitimate instruction to a developer.
