**TLDR:** Production'da 50+ fine-tuned model versiyonu nasıl yönetilir? HuggingFace Hub privat repo + MLflow Model Registry + S3 (parça-parça artifact) hybrid. Versioning convention (semantic versioning + lineage), tags (\`production\`, \`canary\`, \`archive\`), retention policy (eski versiyon ne zaman silinir?). Cookbook'un model card şablonu (LoRA adapter + base + recipe).
