AI-powered 'Code-Diff-Analyzer' found issues on commit 0ebd982.

Path	Line	Severity	Description
prune-block-cache-testing.md	18	low	Documentation (now deleted) contained a curl-pipe-to-shell pattern for installing Rust (`curl ... https://sh.rustup.rs | sh`). While standard for Rust installation, such patterns in shared repo docs can encourage unsafe practices. File is being removed, which is the correct action.
prune-block-cache-testing.md	32	low	Hardcoded developer home directory paths (`/home/bkhishor/`) are present throughout the deleted testing notes, leaking an internal developer username. The file deletion resolves this information disclosure.
