While local development works excellently, network-dependent features are completely blocked in certain environments. + +**The documentation is excellent for teaching Soroban development concepts** but needs better structure to handle real-world constraints like network access issues. + +**Key Takeaway:** The tutorial should not assume testnet access. A local-first approach would make it universally accessible while still teaching all the same concepts. + +**Primary Recommendation:** Restructure the tutorial to prioritize local development, making testnet deployment an optional advanced step after mastering local workflows. + +--- + +**End of Complete Audit Report** +**Total Issues Documented:** 9 +**Critical Blockers:** 3 +**High Priority:** 4 +**Low Priority:** 2 +**Pages Analyzed:** 6 +**Commands Tested:** 25+ +**Success Rate:** 40% (local-only), 0% (network-dependent)
