How Binary Diffs at Scale Actually Work
Block-level delta computation, content-addressed chunking, and why "binary files differ" is a cop-out not a constraint.

Why Perforce Breaks at 200 GB (And What You Can Do About It)
The specific P4 bottlenecks that hit around 150–200 GB depot size: proxy cache invalidation, metadata server load, and client-side OOM during p4 sync.

Anatomy of a Binary Merge Conflict in Unreal Assets
What actually happens inside a .uasset when two engineers edit the same Blueprint graph. Why traditional three-way merge fails, and what block-aware conflict detection looks like instead.

Git LFS vs. Diversion: A Practical Comparison for Game Studios
Git LFS is a pointer layer on top of git — it doesn't solve file locking, branch cost on binary repos, or bake-freshness detection. A direct feature comparison for studios evaluating both.
