Subject: docs: one-prompt architecture plan

ok 2 prompts, the second one was about the test strategy so we could
reuse it. I was thinking of a tool like blossom audit. but i didnt
mention it specifically.

+# 🎉 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

+## Technology Stack
+
+- **actix-web**: HTTP server
+- **git-http-backend**: Git protocol (Rust crate)
+- **nostr-relay-builder**: Nostr relay (rust-nostr)
+- **tokio**: Async runtime
+
+## Implementation Estimate
+
+- **~1,400 lines of code** (similar to reference)
+- **4-6 weeks** for GRASP-01 MVP
+- **Well-documented** with extensive examples
+
+## GRASP Compliance
+
+### GRASP-01 (MVP)
+- ✅ Designed and documented
+- ⏭️ Ready to implement
+
+### GRASP-02 (Proactive Sync)
+- ✅ Architecture designed
+- ⏭️ Future phase
+
+### GRASP-05 (Archive)
+- ✅ Architecture designed
+- ⏭️ Future phase
+
+## Recommendation
+
+✅ **Proceed with implementation**
+
+The architecture is:
+- Technically sound
+- Pragmatic and achievable
+- Superior to hook-based approach
+- Well-documented
+- Testable
+- GRASP-compliant
+
+## Next Steps
+
+1. **Review** [REVIEW_SUMMARY.md](REVIEW_SUMMARY.md)
+2. **Review** [docs/ARCHITECTURE.md](docs/ARCHITECTURE.md)
+3. **Approve** or provide feedback on architecture
+4. **Begin implementation** following [docs/GETTING_STARTED.md](docs/GETTING_STARTED.md)
+
+## Questions?
+
+All design decisions are documented with rationale. If you have questions or want to discuss any aspect, the documentation provides detailed context.
