• 8 comprehensive test cases
• Tests cover happy path and edge cases
• Tests validate both storage keys
• Tests ensure deployment safety
• Proper test documentation

4. Cargo Configuration Updated

• File: contracts/amana_escrow/Cargo.toml

✅ Functional Verification

Safety Check Validation

• Regex pattern correctly matches both DataKey::CngnContract and DataKey::SourceToken
• Contract source contains both keys (verified in DataKey enum)
• Error message is clear and actionable
• No false positives or negatives

Deployment Script Validation

• Script has proper error handling
• All required arguments are validated
• Optional arguments have sensible defaults
• Help text is comprehensive
• Output is clear and actionable
• Contract ID is properly extracted and displayed

Test Coverage Validation

• Tests use proper Soroban SDK patterns
• Tests cover initialization with arbitrary tokens
• Tests validate storage key compatibility
• Tests ensure idempotent initialization
• Tests verify authorization enforcement
• Tests check fee bounds validation
• Tests validate state persistence
• Tests cover edge cases (zero fee, max fee)

---

✅ Acceptance Criteria

Requirement 1: Fix the specific issue

• Root cause identified: overly strict safety check
• Fix implemented: accept both token storage keys
• Issue resolved: local network deployments now work
• Backward compatibility maintained

Requirement 2: CI passes cleanly

• Safety check no longer fails for local networks
• All regression tests validate deployment scenarios
• No new regressions introduced
• WASM build and verification still enforced
• All existing tests continue to pass

Requirement 3: New or updated tests demonstrate the change

• 8 new regression tests added
• Tests cover happy path and error conditions
• Tests validate both storage keys work
• Tests ensure deployment safety guarantees
• Tests prevent future regressions

---

✅ Code Quality

Style & Conventions

• Bash script follows project conventions
