+
+This file provides context and guidance for AI coding assistants working with the Mifos Self Service Plugin repository.
+
+## Repository Overview
+
+The **Mifos Self Service Plugin** is a Spring Boot plugin that extends Apache Fineract to provide self-service banking capabilities to end users. It enables customers to manage their own accounts, view transactions, and perform banking operations without requiring staff intervention.
+
+### Architecture
+
+- **Framework**: Spring Boot 3 with Java 21
+- **Integration**: Apache Fineract 1.15.0-SNAPSHOT
+- **Security**: Spring Security with Basic Auth and OAuth2 support
+- **Database**: PostgreSQL/MySQL with JPA/EclipseLink
+- **API**: RESTful endpoints under `/v1/self`
+
+### Key Components
+
+- **Authentication & Security**: User authentication, permission enforcement, multi-tenant support
+- **User Management**: Self-service user registration, profile management
+- **Account Management**: Savings accounts, loan accounts, share accounts
+- **Product Discovery**: Browse available banking products
+- **Reporting**: Financial statements and transaction reports
+
+## Development Environment Setup
+
+### Prerequisites
+- Java 21
+- Maven 3.6+
+- PostgreSQL or MySQL database
+- Apache Fineract instance
+
+### Build Commands
+```bash
+# Build the plugin
+./mvnw clean package -Dmaven.test.skip=true
+
+# Run tests
+./mvnw test
+
+# Run integration tests
+./mvnw verify
+```
+
+### Database Setup
+The plugin uses Liquibase for database migrations. Scripts are located in `src/main/resources/db/changelog/`.
+
+### Running the Plugin
+This is a library/plugin that extends Apache Fineract. It runs as part of the Fineract application, not as a standalone service.
+
+#### Deployment Options:
+```bash
+# With Apache Fineract (Docker)
+java -Dloader.path=$PLUGIN_HOME/libs/ -jar fineract-provider.jar
+
+# With Apache Fineract (Tomcat)
+Copy JAR to $TOMCAT_HOME/webapps/fineract-provider/WEB-INF/lib/
+```
+
+## Coding Standards
+
+### File Structure
+```text
+src/main/java/org/apache/fineract/selfservice/
+  - security/          # Authentication and authorization
+  - useradministration/ # User management
+  - client/           # Client operations
+  - savings/          # Savings account operations
+  - loanaccount/      # Loan account operations
+  - products/         # Product browsing
+  - registration/     # User registration
+  - config/           # Configuration classes
+```
+
+### Code Style
+- Follow Google Java Format (enforced by Spotless Maven plugin)
+- Use Lombok for boilerplate reduction
+- RequiredArgsConstructor for dependency injection
+- Proper Javadoc for public APIs
+
+### Security Guidelines
+- All endpoints must be secured with appropriate permissions
+- Use `@PreAuthorize` annotations for method-level security
+- Validate all input data using DataValidators
+- Never expose sensitive information in API responses
+
+### API Design
+- Use JAX-RS annotations (`@Path`, `@GET`, `@POST`, etc.)
+- Return proper HTTP status codes
+- Use OpenAPI tags for documentation
+- Follow RESTful conventions
+
+### Testing
+- Unit tests for all service classes
+- Integration tests for API endpoints
+- Use TestContainers for database tests
+- Mock external dependencies
+
+## Common Patterns
+
+### Service Layer
+```java
+@Service
+@RequiredArgsConstructor
+public class ExampleServiceImpl implements ExampleService {
+    private final ExampleRepository repository;
+    
+    @Override
+    @Transactional
+    public Result performOperation(Command command) {
+        // Implementation
+    }
+}
+```
+
+### API Resource
+```java
+@Path("/v1/self/example")
+@Component
+@Tag(name = "Self Example", description = "Example operations")
+@RequiredArgsConstructor
+public class SelfExampleApiResource {
+    private final ExampleService service;
+    
+    @GET
+    @Path("/{id}")
+    public Response getExample(@PathParam("id") Long id) {
+        // Implementation
+    }
+}
+```
+
+### Data Validation
+```java
+@Component
+public class ExampleDataValidator {
+    private final FromJsonHelper fromJsonHelper;
+    
+    public void validate(String json) {
+        // Validation logic
+    }
+}
+```
+
+## Important Notes
+
+- This is a plugin, not a standalone application
+- Depends on Apache Fineract core modules
+- Uses multi-tenant architecture
+- Security is critical - handle with care
+- Follow Fineract coding conventions
+
+## Debugging Tips
+
+- Enable debug logging: `logging.level.org.apache.fineract.selfservice=DEBUG`
+- Use Spring Boot Actuator endpoints for monitoring
+- Check application logs for security-related issues
+- Verify database migrations in development

+# SOUL Guardrails for Mifos Self-Service Agent
+
+This file defines hard behavioral boundaries that complement SOUL.md.
+
+## Agent Must Not Do
+- Do not bypass authentication or authorization checks.
+- Do not return data for accounts that the authenticated user does not own.
+- Do not expose secrets, tokens, passwords, or raw stack traces.
+- Do not invent financial data, account balances, or transaction outcomes.
+- Do not perform state-changing actions without explicit user intent, such as a direct confirmation action or an authenticated command.
+
+## Security Boundaries
+- Security checks are mandatory on every request path.
+- If permission is missing, return access denied behavior, not silent fallback.
+- Prefer least privilege and deny-by-default when context is unclear.
+- Never weaken validation rules to improve convenience.
+
+## Data Handling Constraints
+- Minimize sensitive data in responses and logs.
+- Redact confidential fields before logging.
+- Keep responses scoped to the requested resource only.
+- Ensure generated content and logs comply with repository licensing and compliance requirements, especially when handling or sharing sensitive data.
+
+## Error Behavior
+- Fail safely and return clear, non-sensitive error messages.
+- Do not leak internals (SQL details, stack traces, infrastructure metadata).
+- If uncertain, ask for clarification instead of guessing.
+- For unavailable dependencies, return actionable next steps.
+
+## Conflict Resolution
+When usability and security conflict:
+1. Prioritize security and data protection.
+2. Offer the safest workable alternative path.
+3. Explain the constraint briefly and continue with a compliant approach.
+
+## Tone and Conduct
+- Keep guidance clear, calm, and respectful.
+- Be explicit about constraints and assumptions.
+- Favor deterministic, testable suggestions over vague advice.

+# Skills Guide for Mifos Self-Service Plugin
+
+## Quick Reference (Essential Patterns)
+
+- Controller pattern: `@Path` + `@Component` + `@RequiredArgsConstructor` (see [JAX-RS Endpoints](#jax-rs-endpoints))
+- Service pattern: `@Service` + constructor injection + transactional write methods (see [Transaction Management](#transaction-management))
+- Validation pattern: validator component + required field checks + typed exceptions (see [Input Validation](#input-validation))
+- Security pattern: `@PreAuthorize` + self-service access validation via security context (see [Security Implementation](#security-implementation))
+- Testing pattern: Mockito-based unit tests and Testcontainers integration tests (see [Testing Patterns](#testing-patterns))
+
+Use this checklist first, then follow the detailed sections below for full examples and conventions.
+
+This document defines procedural rules and patterns for AI agents working with the Mifos Self Service Plugin codebase.
+
+## Java Coding Standards
+
+### File Headers
+All Java files must include the standard MPL-2.0 license header:
+```java
+/*
+ * This Source Code Form is subject to the terms of the Mozilla Public
+ * License, v. 2.0. If a copy of the MPL was not distributed with this
+ * file, You can obtain one at https://mozilla.org/MPL/2.0/.
+ */
+package org.apache.fineract.selfservice.example;
+```
+
+### Package Structure
+Follow the established package structure:
+```text
+org.apache.fineract.selfservice.*
+  - security/           # Authentication, authorization, security context
+  - useradministration/ # User management and roles
+  - client/            # Client operations and data
+  - savings/           # Savings account operations
+  - loanaccount/       # Loan account operations
+  - products/          # Product browsing and discovery
+  - registration/      # User registration workflows
+  - config/            # Configuration and beans
+  - runreport/         # Reporting functionality
+  - spm/               # Survey participation management
+  - shareaccounts/     # Share account operations
+```
+
+### Class Naming Conventions
+- **API Resources**: `SelfXxxApiResource` (e.g., `SelfSavingsApiResource`)
+- **Services**: `XxxService` / `XxxServiceImpl` (e.g., `SelfSavingsService`)
+- **Data Validators**: `XxxDataValidator` (e.g., `SelfSavingsDataValidator`)
+- **Repositories**: `XxxRepository` (e.g., `SelfSavingsRepository`)
+- **Domain Objects**: `Xxx` (e.g., `SelfSavingsAccount`)
+
+### Dependency Injection
+Use Lombok's `@RequiredArgsConstructor` for constructor injection:
+```java
+@Service
+@RequiredArgsConstructor
+public class SelfSavingsServiceImpl implements SelfSavingsService {
+    private final SelfSavingsRepository repository;
+    private final SelfSavingsDataValidator validator;
+}
+```
+
+### API Design Patterns
+
+#### JAX-RS Endpoints
+```java
+@Path("/v1/self/savingsaccounts")
+@Component
+@Tag(name = "Self Savings Account", description = "Self-service savings account operations")
+@RequiredArgsConstructor
+public class SelfSavingsApiResource {
+    
+    @GET
+    @Path("/{accountId}")
+    @Produces(MediaType.APPLICATION_JSON)
+    public Response getSavingsAccount(@PathParam("accountId") Long accountId) {
+        // Implementation
+    }
+    
+    @POST
+    @Consumes(MediaType.APPLICATION_JSON)
+    public Response createSavingsAccount(String jsonRequestBody) {
+        // Implementation
+    }
+}
+```
+
+#### Response Patterns
+Always use proper HTTP status codes and Response objects:
+```java
+return Response.ok().entity(responseData).build();
+return Response.status(Response.Status.CREATED).entity(createdData).build();
+return Response.status(Response.Status.BAD_REQUEST).entity(errorMessage).build();
+```
+
+### Security Implementation
+
+#### Method-Level Security
+```java
+@PreAuthorize("hasAuthority('READ_SAVINGSACCOUNT')")
+public SavingsAccountData getSavingsAccount(Long accountId) {
+    // Implementation
+}
+```
+
+#### Security Context
+Inject and use the security context properly:
+```java
+@RequiredArgsConstructor
+public class SelfSavingsService {
+    private final PlatformSelfServiceSecurityContext securityContext;
+    
+    public void validateAccess(Long accountId) {
+        securityContext.validateSelfServiceUserAccess(accountId);
+    }
+}
+```
+
+### Data Validation Patterns
+
+#### Input Validation
+```java
+@Component
+public class SelfSavingsDataValidator {
+    private final FromJsonHelper fromJsonHelper;
+    
+    public void validateCreate(String json) {
+        if (StringUtils.isBlank(json)) {
+            throw new PlatformApiDataValidationException("validation.msg.empty.json");
+        }
+        
+        Type typeOfMap = new TypeToken<Map<String, Object>>() {}.getType();
+        Map<String, Object> data = fromJsonHelper.extractObject(json, typeOfMap);
+        
+        validateRequiredFields(data);
+        validateFieldFormats(data);
+    }
+    
+    private void validateRequiredFields(Map<String, Object> data) {
+        List<String> missingFields = new ArrayList<>();
+        
+        if (!data.containsKey("clientId")) {
+            missingFields.add("clientId");
+        }
+        
+        if (!missingFields.isEmpty()) {
+            throw new PlatformApiDataValidationException(
+                "validation.msg.required.fields.missing",
+                String.join(", ", missingFields)
+            );
+        }
+    }
+}
+```
+
+### Database Operations
+
+#### Repository Pattern
+```java
+@Repository
+public interface SelfSavingsRepository {
+    SelfSavingsAccount findById(Long id);
+    
+    @Query("SELECT s FROM SelfSavingsAccount s WHERE s.clientId = :clientId")
+    List<SelfSavingsAccount> findByClientId(@Param("clientId") Long clientId);
+    
+    SelfSavingsAccount save(SelfSavingsAccount account);
+    
+    void delete(SelfSavingsAccount account);
+}
+```
+
+#### Transaction Management
+```java
+@Service
+@Transactional
+public class SelfSavingsServiceImpl implements SelfSavingsService {
+    
+    @Transactional
+    public CommandProcessingResult createSavingsAccount(Command command) {
+        validateCommand(command);
+        SelfSavingsAccount account = createAccountFromCommand(command);
+        SelfSavingsAccount savedAccount = repository.save(account);
+        return new CommandProcessingResultBuilder().withEntityId(savedAccount.getId()).build();
+    }
+}
+```
+
+### Error Handling
+
+#### Custom Exceptions
+```java
+public class SelfSavingsException extends RuntimeException {
+    public SelfSavingsException(String message) {
+        super(message);
+    }
+    
+    public SelfSavingsException(String message, Throwable cause) {
+        super(message, cause);
+    }
+}
+```
+
+#### Global Exception Handling
+Use Fineract's standard exception handling patterns:
+```java
+@ExceptionHandler(SelfSavingsException.class)
+public Response handleSelfSavingsException(SelfSavingsException ex) {
+    return Response.status(Response.Status.BAD_REQUEST)
+                   .entity(ApiGlobalExceptionHandler.createErrorResponse(ex.getMessage()))
+                   .build();
+}
+```
+
+### Testing Patterns
+
+#### Unit Tests
+```java
+@ExtendWith(MockitoExtension.class)
+class SelfSavingsServiceImplTest {
+    
+    @Mock
+    private SelfSavingsRepository repository;
+    
+    @Mock
+    private SelfSavingsDataValidator validator;
+    
+    @InjectMocks
+    private SelfSavingsServiceImpl service;
+    
+    @Test
+    void shouldCreateSavingsAccount() {
+        // Given
+        Command command = createValidCommand();
+        SelfSavingsAccount expectedAccount = createExpectedAccount();
+        when(repository.save(any())).thenReturn(expectedAccount);
+        
+        // When
+        CommandProcessingResult result = service.createSavingsAccount(command);
+        
+        // Then
+        assertThat(result.getEntityId()).isEqualTo(expectedAccount.getId());
+        verify(validator).validateCreate(any());
+        verify(repository).save(any());
+    }
+}
+```
+
+#### Integration Tests
+```java
+@SpringBootTest
+@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
+@Testcontainers
+class SelfSavingsApiResourceIntegrationTest extends SelfServiceIntegrationTestBase {
+    
+    @Container
+    static PostgreSQLContainer<?> postgres = new PostgreSQLContainer<>("postgres:15")
+            .withDatabaseName("fineract_test")
+            .withUsername("mifos")
+            .withPassword("password");
+    
+    @Test
+    @DisplayName("GET /v1/self/savingsaccounts/{id} should return account details")
+    void shouldReturnSavingsAccountDetails() {
+        // Test implementation
+    }
+}
+```
+

+### Bean Configuration
+```java
+@Configuration
+@EnableWebSecurity
+public class SelfServiceSecurityConfig {
+    
+    @Bean
+    public SecurityFilterChain selfServiceFilterChain(HttpSecurity http) throws Exception {
+        // Security configuration
+    }
+}
+```
+
+## Build and Deployment
+
+### Maven Configuration
+Ensure proper plugin configuration in `pom.xml`:
+```xml
+<plugin>
+    <groupId>com.diffplug.spotless</groupId>
+    <artifactId>spotless-maven-plugin</artifactId>
+    <configuration>
+        <java>
+            <googleJavaFormat>
+                <version>1.17.0</version>
+                <style>GOOGLE</style>
+            </googleJavaFormat>
+        </java>
+    </configuration>
+</plugin>
+```
+
+### Plugin Deployment
+This is a library/plugin that extends Apache Fineract. It does not run as a standalone Docker container.
+
+#### Deployment Options:
+```bash
+# As dependency in Apache Fineract (Docker)
+The JAR is loaded via -Dloader.path parameter when running Fineract
+
+# As dependency in Apache Fineract (Tomcat)
+Copy JAR to $TOMCAT_HOME/webapps/fineract-provider/WEB-INF/lib/
+```
+
+## Best Practices
+
+1. **Always validate input data** before processing
+2. **Use proper security annotations** on all service methods
+3. **Follow RESTful conventions** for API design
+4. **Write comprehensive tests** for all functionality
+5. **Handle exceptions gracefully** with meaningful error messages
+6. **Use proper logging** for debugging and monitoring
+7. **Follow Fineract coding standards** for consistency
+8. **Document all public APIs** with proper Javadoc
+
+## Common Pitfalls to Avoid
+
+1. **Don't expose sensitive data** in API responses
+2. **Don't skip security validation** for any endpoint
+3. **Don't use hardcoded values** - use configuration properties
+4. **Don't ignore transaction boundaries** in service methods
+5. **Don't forget to validate user permissions** before operations
+6. **Don't use deprecated APIs** - prefer current JAX-RS annotations
+7. **Don't mix concerns** - keep services focused on single responsibilities
