+# 🎉 Architecture Investigation Complete
+## Summary
+I have completed a comprehensive investigation of the GRASP protocol, reference implementation, and Rust ecosystem to design the architecture for **ngit-grasp**.
+## Key Finding
+✅ **The `git-http-backend` Rust crate is sufficiently flexible to allow inline authorization logic**
+We do NOT need Git hooks. We can intercept and validate pushes directly in the HTTP handler before spawning Git.
+## Decision
+**Use inline authorization** (not pre-receive hooks)
+### Why This Is Better
+1. **Better UX**: Direct HTTP error responses vs. parsing hook stderr
+2. **Simpler Deployment**: Single Rust binary, no hook management
+3. **Easier Testing**: Pure Rust unit tests, no shell scripts
+4. **Better Performance**: Skip Git spawn for invalid pushes
+5. **Tighter Integration**: Shared state between Git and Nostr components
