+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Role
+
+`multiapps-controller` is the core Multi-Target Application (MTA) deployment service for Cloud Foundry. It orchestrates complex multi-app deployments via BPMN-modeled Flowable 7 workflows that drive calls to the CF Cloud Controller API. It depends on the `multiapps` library (`org.cloudfoundry.multiapps`) for MTA model objects and YAML parsing.
+
+## Security Boundary
+
+This is an **OPEN SOURCE** repository. Never introduce proprietary logic, credentials, or internal company context into this codebase.
+
+## Tech Stack
+
+- **Java 25**, multi-module Maven (11 modules), Spring 6 / Spring Security 6, deployed as a WAR
+- **Flowable 7** for BPMN process orchestration (deploy, undeploy, blue-green deploy workflows)
+- **EclipseLink 4** (JPA) with static weaving via `staticweave-maven-plugin` at compile time
+- **Liquibase** for DB schema migrations; **HikariCP** for connection pooling
+- **Immutables** for generated value objects — IDE annotation processors must be enabled
+- Cloud object store integrations: AWS S3, Azure Blob, GCP, Alibaba OSS (via Apache jclouds + native SDKs)
+- **JaCoCo** + **SonarCloud** for coverage/quality (profiles: `coverage`, `sonar`)
+
+## Module Map
+
+| Module | Purpose |
+|---|---|
+| `multiapps-controller-api` | Swagger-generated REST API models and endpoint interfaces |
+| `multiapps-controller-web` | REST controllers; builds the deployable WAR |
+| `multiapps-controller-process` | Flowable BPMN definitions and step implementations |
+| `multiapps-controller-core` | Domain model, CF client wrappers, core services |
+| `multiapps-controller-persistence` | File artifact storage (DB + object store) |
+| `multiapps-controller-client` | Extends cf-java-client with OAuth, retries, extra models |
+| `multiapps-controller-database-migration` | Tooling to migrate data between DB instances |
+| `multiapps-controller-shutdown-client` | Client for the graceful shutdown API |
+| `multiapps-controller-core-test` | Shared test fixtures for core |
+| `multiapps-controller-persistence-test` | Shared test fixtures for persistence |
+| `multiapps-controller-coverage` | Aggregates JaCoCo reports across all modules |
+
+## Build & Test Commands
+
+```bash
+# Full build (compiles, runs unit tests, packages WAR)
+mvn clean install
+
+# Skip tests for faster packaging
+mvn clean install -DskipTests
+
+# Run unit tests only (integration tests excluded by surefire config)
+mvn clean test
+
+# Run a single test class
+mvn test -pl multiapps-controller-process -Dtest=MyStepTest
+
+# Build a specific module and its dependencies
+mvn clean install -pl multiapps-controller-web --also-make
+
+# Coverage report (aggregate in multiapps-controller-coverage/target/)
+mvn clean install -P coverage
+
+# Sonar analysis
+mvn verify sonar:sonar -P sonar
+```
+
+The deployable WAR is at `multiapps-controller-web/target/multiapps-controller-web-<version>.war`.
+
+Integration tests (`**/*IntegrationTest`) are excluded from the default surefire run.
+
+## Formatting Rule
+
+Before completing any task or committing code, you **MUST** run:
+
+```bash
+mvn spotless:apply
+```
