character (i.e., ensure the file ends with an empty line after that sentence) to
follow POSIX/file-diff conventions.
In `@zk/circuits/merkle/merkle_update_proof.circom`:
- Line 27: The username input signal username[32] allows arbitrary field
elements per slot; add per-element byte-range constraints so each username[i] is
canonical 0..255 (e.g., instantiate a byte-range check or an 8-bit
LessThan/IsLessThan component for each element, or decompose each element into 8
bits and enforce bitness) and apply the same pattern to the other array inputs
noted around lines 39-44; update the security docs wording to remove any claim
of complete closure until these checks are present. Ensure you reference and
modify the username[32] signal handling and the equivalent input signals
mentioned in the diff when implementing these constraints.

Add language specification to fenced code block.
The fenced code block displaying the directory structure should specify a language for proper syntax highlighting and linting compliance.

Add trailing newline at end of file.
The file is missing a trailing newline at the end, which is a common convention and helps with version control diffs.

Fixes #186 - gateway-contract/readme.md is empty — add workspace-level README with build and test instructions
🎯 Summary
The gateway-contract/readme.md file was completely empty, making it difficult for contributors to understand how to build, test, and deploy the Alien Gateway contracts. This PR adds comprehensive documentation with detailed instructions for the entire development workflow.
✅ Changes Made
Added complete workspace-level README with 277 lines of documentation
Documented workspace structure explaining all 4 contracts:
core_contract - Main gateway contract handling core protocol logic
escrow_contract - Escrow service for secure asset holding
factory_contract - Factory contract for deploying new instances
auction_contract - Auction mechanism for alien asset trading
Added build instructions with both cargo and Stellar CLI commands
Added comprehensive test instructions including cargo test, clippy, and fmt
Added detailed deployment instructions for Stellar testnet
Included prerequisites, troubleshooting, and development workflow
🛠️ Technical Details
The README provides:
Step-by-step build commands: cargo build --target wasm32v1-none --release
Test suite commands: cargo test, cargo clippy, cargo fmt
Complete Stellar CLI deployment workflow for testnet
Contract interaction examples and useful commands
Troubleshooting section with common issues and solutions
🧪 Verification
All build commands are verified and follow Stellar/Soroban best practices
Test commands match the workspace structure in Cargo.toml
Deployment instructions include proper network configuration
Commands are tested for syntax and correctness
📋 Acceptance Criteria Met
✅ gateway-contract/readme.md has complete content
✅ Build, test, and deploy commands are correct and follow project standards
✅ Workspace structure is clearly documented
✅ Ready for PR review and merge
This documentation will significantly improve the developer experience for anyone working with the Alien Gateway contracts.
