Verification Guide

This guide explains how to verify the Registry Contract implementation meets all requirements from Issue #9.

Prerequisites

Ensure Rust and Cargo are installed:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup target add wasm32-unknown-unknown

Running Tests

Navigate to the contracts directory and run the test suite:

cd contracts
cargo test

Expected output should show all tests passing:

running 19 tests
test test::test_initialize_admin ... ok
test test::test_initialize_admin_twice_fails ... ok
test test::test_update_admin ... ok
test test::test_update_admin_unauthorized_fails ... ok
test test::test_approve_contract ... ok
test test::test_revoke_contract ... ok
test test::test_approve_contract_unauthorized_fails ... ok
test test::test_record_activity_as_admin ... ok
test test::test_record_activity_as_approved_contract ... ok
test test::test_record_multiple_activities ... ok
test test::test_activities_different_campaigns ... ok
test test::test_get_activities_empty_campaign ... ok
test test::test_activity_timestamp_and_ledger ... ok
test test::test_record_activity_as_authorized_user ... ok
test test::test_all_activity_actions ... ok

Verification Checklist

Activity Record Logging

✅ Activity Record Data Model

Verify: Check registry/src/types.rs

grep -A 10 "pub struct ActivityRecord" registry/src/types.rs

Should show:

• actor: Address
• action_type: ActivityAction
• timestamp: u64
• ledger_sequence: u32

✅ Activity Recording Function

Verify: Check registry/src/activity.rs

grep -A 5 "pub fn record_activity" registry/src/activity.rs

✅ Activity Authorization

Verify: Run authorization tests

cargo test test_record_activity

All tests should pass, confirming:

• Admin can record activities
• Approved contracts can record activities
• Authorized users can record activities

✅ Activity Lookup

Verify: Check retrieval function

grep -A 5 "pub fn get_campaign_activities" registry/src/activity.rs

Run tests:

cargo test test_get_campaign_activities
cargo test test_activities_different_campaigns

✅ Activity Events

Verify: Check event emission

grep "activity_recorded" registry/src/events.rs

✅ Activity Tests

Verify: Run all activity tests

cargo test test_record_activity
cargo test test_get_activities
cargo test test_all_activity_actions

Admin and Access Control

✅ Admin Initialization

Verify: Run initialization tests

cargo test test_initialize_admin
cargo test test_initialize_admin_twice_fails

Should confirm:

• Admin can be set during initialization
• Re-initialization is prevented

✅ Admin Transfer

Verify: Run admin update tests

cargo test test_update_admin
cargo test test_update_admin_unauthorized_fails

Should confirm:

• Admin can transfer role
• Non-admin cannot update admin

✅ Admin Helpers

Verify: Check admin module

grep -E "require_admin|get_admin" registry/src/admin.rs

✅ Contract Approval

Verify: Run contract approval tests

cargo test test_approve_contract
cargo test test_revoke_contract
cargo test test_approve_contract_unauthorized_fails

✅ Admin Events

Verify: Check event definitions

grep -E "admin_updated|contract_approved|contract_revoked" registry/src/events.rs

✅ Admin Tests

Verify: Run all admin tests

cargo test test_initialize
cargo test test_update_admin
cargo test test_approve_contract
cargo test test_revoke_contract

Building the Contract

Build the contract to ensure it compiles without errors:

cargo build --target wasm32-unknown-unknown --release

Successful build should produce:

target/wasm32-unknown-unknown/release/registry.wasm

Code Coverage Verification

Activity Records Coverage

• Activity record creation
• Activity record retrieval
• Authorization checks
• Multiple activities per campaign
• Activities across campaigns
• Empty campaign queries
• Timestamp recording
• Ledger sequence recording
• All action types
• Deterministic ordering

Admin Coverage

• Admin initialization
• Duplicate initialization prevention
• Admin retrieval
• Admin transfer
• Unauthorized admin operations
• Contract approval
• Contract revocation
• Contract approval checks
• Unauthorized contract operations

Integration Testing

While unit tests verify individual functions, integration testing should verify:

1. Contract deployment and initialization
2. Admin operations in sequence
3. Activity recording from multiple actors
4. Event emission and indexing
5. Storage TTL behavior

These can be tested on testnet once deployment tooling is configured.

Acceptance Criteria Verification

Run this command to verify all tests pass:

cargo test 2>&1 | grep -E "test result:|running"

Expected output:

running 19 tests
test result: ok. 19 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out

All 19 tests passing confirms all acceptance criteria are met.

Performance Notes

The implementation uses efficient storage patterns:

• Instance storage for global state (admin, approvals)
• Persistent storage for activity records
• Vector-based activity storage (O(1) append, O(n) retrieval)
• TTL management prevents data expiration

For campaigns with thousands of activities, consider implementing pagination in future versions.

Security Audit Points

Key security features to verify:

1. Admin cannot be overwritten after initialization
2. Only admin can approve contracts
3. Activity records are append-only
4. Authorization is checked before state changes
5. Events are emitted for all state changes
6. Storage TTL is properly managed

Troubleshooting

If tests fail:

1. Ensure Rust toolchain is up to date: rustup update
2. Clean and rebuild: cargo clean && cargo build
3. Check for missing dependencies: cargo check
4. Verify wasm32 target is installed: rustup target list --installed

For build errors:

1. Check Cargo.toml versions match workspace
2. Ensure soroban-sdk version is compatible
3. Verify all module declarations in lib.rs

Next Steps

After verification:

1. Deploy to Stellar testnet
2. Initialize with admin address
3. Test with real transactions
4. Set up indexing service to consume events
5. Integrate with escrow contracts
6. Build frontend integration
