68% Git test parity in Rust with transparent cell-by-cell failure breakdowns.

Strengths
  • Runs upstream Git test suite with 28,247 assertions and per-category parity scores.
  • Outperforms git on medium and large repos in wall-clock benchmarks.
  • Honest about limitations—shows failing tests publicly instead of hiding them.
Weaknesses
  • 32% test failure rate means not production-ready for critical workflows yet.
  • Transport and protocol layers at 41-60% parity lag behind plumbing operations.
Target Audience
