Unique: Leverages Git's native version control semantics to provide specification versioning with commit-level granularity and full change history. This enables explicit version pinning without requiring a separate versioning system.

vs others: More transparent than alternatives that version specifications outside Git, since Git provides native diff, blame, and history capabilities that make specification changes auditable and reviewable.
