WalkthroughThe change removes legacy Nix dependency extraction and benchmark scripts, deletes their generated artifacts, and updates the remaining real-world dataset with ChangesReal-world data pipeline

Do not publish fallback placeholders as resolved dependencies.
The refreshed python314 and nodejs_24 records contain nix-store:/...-resolved-* identifiers. real_world_data.py creates these values only in its fallback path when Nix resolution fails. They are synthetic identifiers, not paths returned by nix-store -qR.
Regenerate the dataset with successful Nix resolution, or make generation fail when fallback data would be written.

Compute the package count from the actual platform results.
python314 and nodejs_24 are listed only under debian-sid, but Line 423 multiplies the Debian package count by the number of platforms. The generated JSON reports 105 packages even though the platform maps contain 96 package records.
Sum the package counts from all_results instead.
Proposed fix
- "packages_analyzed": len(PLATFORMS.get("debian-sid", [])) * len(platforms),
+ "packages_analyzed": sum(
+ len(platform_data["packages"]) for platform_data in all_results.values()

Split nix-store output on actual line breaks.
nix-store -qR returns one path per line. In Python, .split("\\n") searches for a literal backslash followed by n, so successful output is treated as one dependency record. Use .splitlines() before deduplication.
Proposed fix
- d.strip() for d in qr_result.stdout.strip().split("\\n") if d.strip()
+ d.strip() for d in qr_result.stdout.splitlines() if d.strip()📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
