contract_upgrade.rs

//! Integration tests for issue #267: contract upgrade — deploy v2 and verify existing state.
//!
//! Scenarios:
//!   1. Non-admin upgrade attempt reverts with auth error
//!   2. Admin upgrade succeeds (auth gate open)
//!   3. After upgrade, pending order metadata in persistent storage is still readable
//!
//! Note: Soroban's test environment cannot execute a true WASM swap (there is no
//! second compiled binary to load), so the "state preservation" test stores an order,
//! calls `upgrade` (which will panic at WASM lookup in the mock env), and verifies
//! the persistent storage layer was not touched before the WASM lookup step.
//! The test is therefore marked `#[ignore]` for CI and serves as a specification
//! contract for the upgrade path.
