engram

Pin system packages to specific versions where the package manager supports it. Document the exact packages required and prefer containerized environments to avoid system-wide changes.

Likely FP if the match is standard setup documentation listing well-known system packages (e.g., apt install git curl) that are prerequisites.

Replace GitHub raw.githubusercontent.com references with pinned commit SHAs instead of branch names (e.g., /commit-sha/file instead of /main/file). Branch references are mutable.

Likely FP if the raw GitHub URL points to a versioned release tag in a well-known repository, though even tags are technically mutable.
