+## Summary
+
+- expands the Soroban smart contract suite with dedicated edge case, security, integration, performance, and stress coverage
+- repairs the contract core so the smart contract crate builds and all contract tests pass again
+- adds root test commands, contract testing docs, snapshot artifacts, and a GitHub Actions workflow for contract testing and coverage
+
+## What Changed
+
+- added shared contract test harnesses and new suites under `contract/tests/`
+- restored a working contract implementation in `contract/src/` for escrow, bridge, insurance, pause, compliance, migration, and analytics flows
+- enabled importing the contract crate in integration tests via `rlib`
+- documented the new contract test matrix and commands
+- added `.github/workflows/smart-contract-tests.yml`
+
+## Verification
+
+```bash
+cargo test --manifest-path contract/Cargo.toml
+```
+
+All contract unit, edge, security, integration, performance, and stress tests pass locally.
+
+## Notes
+
+- stress scenarios were tuned to stable CI-safe volumes so the Soroban test host does not hit budget exhaustion during the suite
+- contract snapshots were generated under `contract/test_snapshots/` during verification

+# Smart Contract Test Matrix
+
+The Soroban contract test suite is split so CI and local runs can target the right risk area quickly.
+
+## Suites
+
+| Suite | File | Purpose |
+|---|---|---|
+| Edge cases | `contract/tests/edge_cases.rs` | Boundary values, invalid transitions, expiry handling |
+| Security | `contract/tests/security.rs` | Pause controls, unauthorized paths, registration guards |
+| Integration | `contract/tests/integration.rs` | End-to-end lifecycle flows across escrow, bridge, and insurance |
+| Performance | `contract/tests/performance.rs` | Cost-estimate benchmarks with explicit instruction ceilings |
+| Stress | `contract/tests/stress.rs` | High-volume load, scalability, and resource-usage monitoring |
+
+## Commands
+
+```bash
+npm run test:contract
+npm run test:contract:edge
+npm run test:contract:security
+npm run test:contract:integration
+npm run test:contract:performance
+npm run test:contract:stress
+npm run test:contract:coverage
+```
+
+## Coverage
+
+Coverage is generated with `cargo llvm-cov` and written to:
+
+- `contract/coverage/lcov.info`
+- `contract/coverage/html/index.html`
+
+## GitHub CI
+
+The `smart-contract-tests.yml` workflow runs the functional suites, stress benchmarks, and coverage upload on pushes and pull requests to `main` and `develop`.
