Context

This backlog item is for dreamgeneX/stargate-contracts and tracks a documentation related to README.md and docs/. It is derived from the planned Stargate work around contract correctness, Soroban treasury workflows, compliance gates, docs, testing, and local developer experience.

Scope

• Review the current Rust/Soroban implementation and ABI impact.
• Make the smallest contract, test, documentation, or tooling change needed for this item.
• Keep generated ABI metadata and snapshots in sync when behavior changes.

Acceptance criteria

• The behavior or documentation described in the title is implemented or clearly specified.
• Relevant tests, snapshots, or verification notes are added.
• cargo fmt --all, cargo clippy -- -D warnings, and cargo test are considered before closing.
