+
+A Claude hook in `.claude/settings.json` runs `.claude/hooks/pre-push.sh`
+before every `git push`. The push is blocked if any check fails. The checks:
+
+- `make fmt`
+- `make clippy` (runs clippy with `-D warnings`)
+- `RUSTDOCFLAGS="-D warnings" cargo doc --no-deps`
+
+Clippy and doc warnings are hard failures.

+## Testing
+
+### Integration Tests
+
+Integration tests live in `tests/` and are gated behind the `test-utils` Cargo feature via `required-features` in `Cargo.toml`. They are not compiled by `cargo test` alone — use `make test-all` or `cargo test --features test-utils` to build and run them. They require network access (real RPC endpoints or Anvil).
+
+### Simulation Harness (Offline Tests)
+
+`src/test_utils/` provides a testing harness for offline simulation testing, gated with `#[cfg(any(test, feature = "test-utils"))]`:
+
+- `TestDbBuilder` - Create in-memory EVM state
+- `TestSimEnvBuilder` - Create `RollupEnv`/`HostEnv` without RPC
+- `TestBlockBuildBuilder` - Build blocks with `BlockBuild`
+- `basic_scenario()`, `gas_limit_scenario()` - Pre-configured test scenarios
+
+## Workflow
+
+After completing a set of changes, always run `make fmt` and `make clippy` and fix any issues before committing.
+
 ## Local Development
 
 For local SDK development, uncomment the `[patch.crates-io]` section in Cargo.toml to point to local signet-sdk paths.

 ## ✅ Testing
 
+### Unit Tests
+
+```bash
+make test
+```
+
+### Integration Tests
+
+Integration tests require network access (RPC endpoints or Anvil) and are gated behind the `test-utils` Cargo feature. They are not compiled by default.
+
+```bash
+make test-all                                            # Run all tests (unit + integration)
+cargo test --features test-utils --test block_builder_test  # Run a specific integration test
+```
+
+### Deployment Verification
