# Business Loop Generation Engine Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Build a generic business-loop generation layer so one-click generation produces runnable workflows with state transitions, quantity changes, record creation, page buttons, and auditable coverage instead of CRUD-only projects.

**Architecture:** Add a structured `BusinessLoopPlan` between app-blueprint generation and database generation. The plan is persisted on `front_project`, passed into database and business-action prompts, audited against generated schema and DSL actions, then used to place business action buttons into page designs.

**Tech Stack:** Java 8, Spring Boot, MyBatis XML, Fastjson2, Jackson ObjectMapper, JUnit4, Mockito, Vue 3, Element Plus, Node source-level tests.

        public void setExpectedResults(List<String> expectedResults) { this.expectedResults = expectedResults; }
    }
}
```

- [ ] **Step 2: Create the audit result DTO**

```java
package com.ruoyi.generator.domain.front.dto;

import java.util.ArrayList;
import java.util.List;

public class BusinessLoopAuditResult
{
    private boolean complete;
    private int loopActions;
    private int stateTransitions;
    private int quantityRules;
    private int recordRules;
    private List<String> missingRequiredActions = new ArrayList<String>();
    private List<String> errors = new ArrayList<String>();

    public boolean isComplete() { return complete; }
    public void setComplete(boolean complete) { this.complete = complete; }
    public int getLoopActions() { return loopActions; }
    public void setLoopActions(int loopActions) { this.loopActions = loopActions; }
    public int getStateTransitions() { return stateTransitions; }
    public void setStateTransitions(int stateTransitions) { this.stateTransitions = stateTransitions; }
    public int getQuantityRules() { return quantityRules; }
    public void setQuantityRules(int quantityRules) { this.quantityRules = quantityRules; }
    public int getRecordRules() { return recordRules; }
    public void setRecordRules(int recordRules) { this.recordRules = recordRules; }
    public List<String> getMissingRequiredActions() { return missingRequiredActions; }
    public void setMissingRequiredActions(List<String> missingRequiredActions) { this.missingRequiredActions = missingRequiredActions; }
    public List<String> getErrors() { return errors; }
    public void setErrors(List<String> errors) { this.errors = errors; }
}
```

- [ ] **Step 3: Create the loop-plan request DTO**

```java
package com.ruoyi.generator.domain.front.dto;

public class GenerateBusinessLoopPlanRequest
{
    private String projectName;
    private String projectDesc;
    private String industryTemplate;
    private String extraRequirements;
    private String appBlueprint;

    public String getProjectName() { return projectName; }
    public void setProjectName(String projectName) { this.projectName = projectName; }
    public String getProjectDesc() { return projectDesc; }
    public void setProjectDesc(String projectDesc) { this.projectDesc = projectDesc; }
    public String getIndustryTemplate() { return industryTemplate; }
    public void setIndustryTemplate(String industryTemplate) { this.industryTemplate = industryTemplate; }
    public String getExtraRequirements() { return extraRequirements; }
    public void setExtraRequirements(String extraRequirements) { this.extraRequirements = extraRequirements; }
    public String getAppBlueprint() { return appBlueprint; }
    public void setAppBlueprint(String appBlueprint) { this.appBlueprint = appBlueprint; }
}
```

- [ ] **Step 4: Extend generation request DTOs**

In `GenerateDatabaseRequest.java` and `GenerateBusinessBlueprintRequest.java`, add:

```java
private String businessLoopPlan;

public String getBusinessLoopPlan() { return businessLoopPlan; }
public void setBusinessLoopPlan(String businessLoopPlan) { this.businessLoopPlan = businessLoopPlan; }
```

- [ ] **Step 5: Extend one-click result contracts**

In `OneClickProjectGenerationReport.java`, add `import java.util.ArrayList;` and `import java.util.List;`, then add:

```java
private boolean businessLoopComplete;
private int loopActions;
private int stateTransitions;
private int quantityRules;
private int recordRules;
private List<String> missingRequiredActions = new ArrayList<String>();

public boolean isBusinessLoopComplete() { return businessLoopComplete; }
public void setBusinessLoopComplete(boolean businessLoopComplete) { this.businessLoopComplete = businessLoopComplete; }
public int getLoopActions() { return loopActions; }
public void setLoopActions(int loopActions) { this.loopActions = loopActions; }
public int getStateTransitions() { return stateTransitions; }
public void setStateTransitions(int stateTransitions) { this.stateTransitions = stateTransitions; }
public int getQuantityRules() { return quantityRules; }
public void setQuantityRules(int quantityRules) { this.quantityRules = quantityRules; }
public int getRecordRules() { return recordRules; }
public void setRecordRules(int recordRules) { this.recordRules = recordRules; }
public List<String> getMissingRequiredActions() { return missingRequiredActions; }
public void setMissingRequiredActions(List<String> missingRequiredActions) { this.missingRequiredActions = missingRequiredActions; }
```

In `OneClickProjectGenerationResult.java`, add:

```java
public static final String STAGE_BUSINESS_LOOP_PLAN = "BUSINESS_LOOP_PLAN";
public static final String STAGE_DATABASE_LOOP_AUDIT = "DATABASE_LOOP_AUDIT";
public static final String STAGE_BUSINESS_LOOP_AUDIT = "BUSINESS_LOOP_AUDIT";
```

- [ ] **Step 6: Persist the loop plan on FrontProject**

In `FrontProject.java`, add:

```java
private String businessLoopPlan;

public String getBusinessLoopPlan() { return businessLoopPlan; }
public void setBusinessLoopPlan(String businessLoopPlan) { this.businessLoopPlan = businessLoopPlan; }
```

In `FrontProjectMapper.xml`, add to `FrontProjectResult`:

```xml
<result property="businessLoopPlan" column="business_loop_plan" />
```

Add `business_loop_plan` to the `selectFrontProjectVo` column list immediately after `app_blueprint`.

Add insert mappings:

```xml
<if test="businessLoopPlan != null">business_loop_plan,</if>
```

and:

```xml
<if test="businessLoopPlan != null">#{businessLoopPlan},</if>
```

Add update mapping:

```xml
<if test="businessLoopPlan != null">business_loop_plan = #{businessLoopPlan},</if>
```

- [ ] **Step 7: Add SQL migrations**

In `sql/front_project_upgrade.sql`, append:

```sql
ALTER TABLE front_project
    ADD COLUMN business_loop_plan longtext NULL COMMENT '业务闭环计划' AFTER app_blueprint;
```

In `sql/db.sql`, update the `front_project` DDL to include:

```sql
business_loop_plan longtext NULL COMMENT '业务闭环计划',
```

Place it after `app_blueprint`.

- [ ] **Step 8: Run focused compile check**

Run:

```powershell
mvn -q -pl ruoyi-generator -DskipTests compile
```

Expected: compile succeeds. If it fails, fix only missing imports, duplicate methods, or mapper column spelling in files touched by this task.

- [ ] **Step 9: Commit**

```powershell
git add -- ruoyi-generator/src/main/java/com/ruoyi/generator/domain/front/dto/BusinessLoopPlan.java ruoyi-generator/src/main/java/com/ruoyi/generator/domain/front/dto/BusinessLoopAuditResult.java ruoyi-generator/src/main/java/com/ruoyi/generator/domain/front/dto/GenerateBusinessLoopPlanRequest.java ruoyi-generator/src/main/java/com/ruoyi/generator/domain/front/dto/GenerateDatabaseRequest.java ruoyi-generator/src/main/java/com/ruoyi/generator/domain/front/dto/GenerateBusinessBlueprintRequest.java ruoyi-generator/src/main/java/com/ruoyi/generator/domain/front/dto/OneClickProjectGenerationReport.java ruoyi-generator/src/main/java/com/ruoyi/generator/domain/front/dto/OneClickProjectGenerationResult.java ruoyi-generator/src/main/java/com/ruoyi/generator/domain/front/FrontProject.java ruoyi-generator/src/main/resources/mapper/front/FrontProjectMapper.xml sql/db.sql sql/front_project_upgrade.sql
git commit -m "Add business loop generation contracts"
```

private String loopPlanResponse()
{
    return loopPlanJson();
}
```

Add imports in the test:

```java
import com.ruoyi.generator.domain.front.dto.BusinessLoopPlan;
import com.ruoyi.generator.domain.front.dto.GenerateBusinessLoopPlanRequest;
```

- [ ] **Step 2: Extend IAiGenerateService**

```java
BusinessLoopPlan generateBusinessLoopPlan(Long userId, Long projectId, GenerateBusinessLoopPlanRequest request);
```

Add imports for `BusinessLoopPlan` and `GenerateBusinessLoopPlanRequest`.

- [ ] **Step 3: Add service dependencies**

In `AiGenerateServiceImpl`, add:

```java
@Autowired
private BusinessLoopPlanValidator businessLoopPlanValidator;
```

In `AiGenerateServiceImplTest.setUp`, add:

```java
setField("businessLoopPlanValidator", new BusinessLoopPlanValidator());
```

- [ ] **Step 4: Implement generateBusinessLoopPlan**

Add this method to `AiGenerateServiceImpl`:

```java
@Override
@Transactional
public BusinessLoopPlan generateBusinessLoopPlan(Long userId, Long projectId, GenerateBusinessLoopPlanRequest request)
{
    assertFrontUserLoggedIn(userId);
    FrontProject project = getProject(userId, projectId);
    String prompt = buildBusinessLoopPlanPrompt(project, request);
    long start = System.currentTimeMillis();
    FrontProjectGeneration generation = newGeneration(projectId, userId, prompt, "business_loop_plan");
    try
    {
        String aiContent = deepSeekClient.chat(prompt);
        BusinessLoopPlan plan = parseBusinessLoopPlanResponse(aiContent);
        businessLoopPlanValidator.validate(plan);
        markBusinessLoopPlanGenerated(projectId, plan, request);
        generation.setResponsePayload(aiContent);
        generation.setSuccess("1");
        generation.setElapsedMs(System.currentTimeMillis() - start);
        generationRecordService.insert(generation);
        return plan;
    }
    catch (RuntimeException e)
    {
        generation.setSuccess("0");
        generation.setErrorMessage(sanitizeErrorMessage(e.getMessage()));
        generation.setElapsedMs(System.currentTimeMillis() - start);
        generationRecordService.insert(generation);
        throw e;
    }
}
```

- [ ] **Step 5: Add loop-plan prompt and parsing helpers**

Add these helpers to `AiGenerateServiceImpl`:

```java
private String buildBusinessLoopPlanPrompt(FrontProject project, GenerateBusinessLoopPlanRequest request)
{
    StringBuilder prompt = new StringBuilder();
    prompt.append("Generate a generic business loop plan for the target generated project. Return JSON only matching the BusinessLoopPlan shape.\n");
    prompt.append("Do not generate CRUD. Do not generate code, SQL, database tables, or menu rows.\n");
    prompt.append("The plan must contain at least one required end-to-end workflow with a state transition.\n");
    prompt.append("The plan must contain quantity change or record creation rules, and should contain both when the domain supports them.\n");
    prompt.append("Use action codes in lowercase snake_case. Required actions must be executable later with safe DSL effects: INSERT_ROW, UPDATE_FIELDS, SET_STATUS, INCREASE_NUMBER, DECREASE_NUMBER.\n");
    prompt.append("If the project name is clear, infer the loop without asking for more text. Library borrow, order, approval, inventory, appointment, repair, and leave systems must not fall back to CRUD.\n");
    prompt.append("Project name: ").append(firstNonBlank(request == null ? null : request.getProjectName(), project.getProjectName())).append("\n");
    prompt.append("Project description: ").append(firstNonBlank(request == null ? null : request.getProjectDesc(), project.getProjectDesc())).append("\n");
    prompt.append("Industry template: ").append(firstNonBlank(request == null ? null : request.getIndustryTemplate(), project.getIndustryTemplate())).append("\n");
    prompt.append("Extra requirements: ").append(request == null ? "" : StringUtils.defaultString(request.getExtraRequirements())).append("\n");
    prompt.append("Confirmed app blueprint JSON: ").append(request == null ? "" : StringUtils.defaultString(request.getAppBlueprint())).append("\n");
    return prompt.toString();
}

private BusinessLoopPlan parseBusinessLoopPlanResponse(String aiContent)
{
    String jsonText = extractJson(aiContent);
    BusinessLoopPlan plan = JSON.parseObject(jsonText, BusinessLoopPlan.class);
    if (plan == null)
    {
        throw new ServiceException("AI did not return a business loop plan");
    }
    return plan;
}

private void markBusinessLoopPlanGenerated(Long projectId, BusinessLoopPlan plan, GenerateBusinessLoopPlanRequest request)
{
    FrontProject project = new FrontProject();
    project.setProjectId(projectId);
    project.setPreviewStatus("0");
    project.setBusinessLoopPlan(JSON.toJSONString(plan));
    project.setRequirementKeyword(request == null ? null : request.getExtraRequirements());
    project.setProjectDesc(request == null ? null : request.getProjectDesc());
    project.setIndustryTemplate(request == null ? null : request.getIndustryTemplate());
    frontProjectMapper.updateFrontProject(project);
}
```

- [ ] **Step 6: Add business loop prompt propagation**

In `buildPrompt`, after `appendAppBlueprintConstraints(prompt, project, request);`, add:

```java
appendBusinessLoopDatabaseConstraints(prompt, project, request);
```

Add:

```java
private void appendBusinessLoopDatabaseConstraints(StringBuilder prompt, FrontProject project, GenerateDatabaseRequest request)
{
    String businessLoopPlan = firstNonBlank(request == null ? null : request.getBusinessLoopPlan(), project.getBusinessLoopPlan());
    if (StringUtils.isBlank(businessLoopPlan))
    {
        return;
    }
    prompt.append("Business loop plan JSON: ").append(businessLoopPlan).append("\n");
    prompt.append("Database generation constraints from the business loop plan:\n");
    prompt.append("- Core objects must map to generated business tables.\n");
    prompt.append("- State machines must have the requested status field on the requested table.\n");
    prompt.append("- Quantity rules must have numeric fields such as stock, available_count, balance, or quantity.\n");
    prompt.append("- Record rules must have record tables and reference fields needed by required actions.\n");
}
```

In `buildBusinessBlueprintPrompt`, after `appendBusinessAppBlueprintConstraints(prompt, project, request);`, add:

```java
appendBusinessLoopActionConstraints(prompt, project, request);
```

Add:

```java
private void appendBusinessLoopActionConstraints(StringBuilder prompt, FrontProject project, GenerateBusinessBlueprintRequest request)
{
    String businessLoopPlan = firstNonBlank(request == null ? null : request.getBusinessLoopPlan(), project.getBusinessLoopPlan());
    if (StringUtils.isBlank(businessLoopPlan))
    {
        return;
    }
    prompt.append("Business loop plan JSON: ").append(businessLoopPlan).append("\n");
    prompt.append("Every required action in the business loop plan must have one matching businessActions entry.\n");
    prompt.append("Actions with stateTransitions must emit SET_STATUS or UPDATE_FIELDS effects.\n");
    prompt.append("Actions with quantityEffects must emit INCREASE_NUMBER or DECREASE_NUMBER effects.\n");
    prompt.append("Actions with recordEffects must emit INSERT_ROW or UPDATE_FIELDS effects against the record table.\n");
}
```

- [ ] **Step 7: Run AI service tests**

Run:

```powershell
mvn -q -pl ruoyi-generator -Dtest=AiGenerateServiceImplTest test
```

Expected: existing tests and new loop-plan tests pass.

- [ ] **Step 8: Commit**

```powershell
git add -- ruoyi-generator/src/main/java/com/ruoyi/generator/service/front/IAiGenerateService.java ruoyi-generator/src/main/java/com/ruoyi/generator/service/front/AiGenerateServiceImpl.java ruoyi-generator/src/test/java/com/ruoyi/generator/service/front/AiGenerateServiceImplTest.java
git commit -m "Generate and propagate business loop plans"

### Task 4: One-Click Orchestration and Audit Enforcement

**Files:**
- Modify: `ruoyi-generator/src/main/java/com/ruoyi/generator/service/front/OneClickProjectGenerationServiceImpl.java`
- Test: `ruoyi-generator/src/test/java/com/ruoyi/generator/service/front/OneClickProjectGenerationServiceImplTest.java`

- [ ] **Step 1: Add failing orchestration tests**

In `OneClickProjectGenerationServiceImplTest`, add a mock field:

```java
@Mock
private BusinessLoopCoverageValidator businessLoopCoverageValidator;
```

In `setUp`, add:

```java
setField("businessLoopCoverageValidator", businessLoopCoverageValidator);
```

Add this test:

```java
@Test
public void generateRunsBusinessLoopPlanBeforeDatabaseAndAuditsCoverage()
{
    AiGenerationTask task = oneClickTask();
    AiGenerationTaskCreateRequest request = request();
    FrontProject project = project();
    AppBlueprintDesign appBlueprint = new AppBlueprintDesign();
    BusinessLoopPlan loopPlan = loopPlan();
    DatabaseDesignResponse database = database();
    BusinessActionDesign action = businessAction("confirm_borrow");
    BusinessLoopAuditResult databaseAudit = completeAudit();
    BusinessLoopAuditResult actionAudit = completeAudit();

    when(frontProjectService.getProject(10L, 20L)).thenReturn(project);
    when(aiGenerateService.generateAppBlueprint(eq(10L), eq(20L), any(GenerateAppBlueprintRequest.class))).thenReturn(appBlueprint);
    when(aiGenerateService.generateBusinessLoopPlan(eq(10L), eq(20L), any(GenerateBusinessLoopPlanRequest.class))).thenReturn(loopPlan);
    when(aiGenerateService.generateDatabase(eq(10L), eq(20L), any(GenerateDatabaseRequest.class))).thenReturn(database);
    when(businessLoopCoverageValidator.auditDatabase(eq(loopPlan), eq(database))).thenReturn(databaseAudit);
    when(aiGenerateService.generateBusinessBlueprint(eq(10L), eq(20L), any(GenerateBusinessBlueprintRequest.class))).thenReturn(Collections.singletonList(action));
    when(businessLoopCoverageValidator.auditBusinessActions(eq(loopPlan), any())).thenReturn(actionAudit);
    when(frontendPageDesignService.initializePageDesigns(10L, 20L, "frontend")).thenReturn(initResponse());
    when(frontendPageDesignService.initializePageDesigns(10L, 20L, "admin")).thenReturn(initResponse());
    when(frontProjectRunPreviewService.start(10L, 20L)).thenReturn(runningPreview());

    OneClickProjectGenerationResult result = service.generate(task, request);

    assertTrue(result.getReport().isBusinessLoopComplete());
    assertEquals(1, result.getReport().getLoopActions());
    InOrder inOrder = inOrder(aiGenerateService, businessLoopCoverageValidator, frontendPageDesignService);
    inOrder.verify(aiGenerateService).generateAppBlueprint(eq(10L), eq(20L), any(GenerateAppBlueprintRequest.class));
    inOrder.verify(aiGenerateService).generateBusinessLoopPlan(eq(10L), eq(20L), any(GenerateBusinessLoopPlanRequest.class));
    inOrder.verify(aiGenerateService).generateDatabase(eq(10L), eq(20L), any(GenerateDatabaseRequest.class));
    inOrder.verify(businessLoopCoverageValidator).auditDatabase(eq(loopPlan), eq(database));
    inOrder.verify(aiGenerateService).generateBusinessBlueprint(eq(10L), eq(20L), any(GenerateBusinessBlueprintRequest.class));
    inOrder.verify(businessLoopCoverageValidator).auditBusinessActions(eq(loopPlan), any());
    inOrder.verify(frontendPageDesignService).initializePageDesigns(10L, 20L, "frontend");
}

@Test
public void generateFailsWhenBusinessLoopAuditIsIncomplete()
{
    stubSuccessfulGeneration(project());
    BusinessLoopPlan loopPlan = loopPlan();
    when(aiGenerateService.generateBusinessLoopPlan(eq(10L), eq(20L), any(GenerateBusinessLoopPlanRequest.class))).thenReturn(loopPlan);
    BusinessLoopAuditResult failedAudit = new BusinessLoopAuditResult();
    failedAudit.setComplete(false);
    failedAudit.getErrors().add("Missing field available_count on table book_info");
    when(businessLoopCoverageValidator.auditDatabase(eq(loopPlan), any(DatabaseDesignResponse.class))).thenReturn(failedAudit);

    try
    {
        service.generate(oneClickTask(), request());
        fail("Expected OneClickProjectGenerationException");
    }
    catch (OneClickProjectGenerationException e)
    {
        assertEquals(OneClickProjectGenerationResult.STAGE_DATABASE_LOOP_AUDIT, e.getResult().getFailedStage());
        assertTrue(e.getResult().getErrorMessage().contains("available_count"));
    }
}
```

Add helper methods:

```java
private BusinessLoopPlan loopPlan()
{
    BusinessLoopPlan plan = new BusinessLoopPlan();
    BusinessLoopPlan.BusinessLoopAction action = new BusinessLoopPlan.BusinessLoopAction();
    action.setCode("confirm_borrow");
    action.setRequired(true);
    action.setOwnerTable("borrow_record");
    plan.getActions().add(action);
    BusinessLoopPlan.BusinessLoopStateMachine stateMachine = new BusinessLoopPlan.BusinessLoopStateMachine();
    stateMachine.setTableName("borrow_record");
    stateMachine.setStatusField("borrow_status");
    BusinessLoopPlan.BusinessLoopStateTransition transition = new BusinessLoopPlan.BusinessLoopStateTransition();
    transition.setActionCode("confirm_borrow");
    transition.setFromState("pending");
    transition.setToState("borrowing");
    stateMachine.getTransitions().add(transition);
    plan.getStateMachines().add(stateMachine);
    BusinessLoopPlan.BusinessLoopQuantityEffect quantity = new BusinessLoopPlan.BusinessLoopQuantityEffect();
    quantity.setActionCode("confirm_borrow");
    quantity.setTableName("book_info");
    quantity.setQuantityField("available_count");
    plan.getQuantityRules().add(quantity);
    return plan;
}

private DatabaseDesignResponse database()
{
    DatabaseDesignResponse database = new DatabaseDesignResponse();
    database.setProjectId(20L);
    database.setTables(Collections.singletonList(new DatabaseTableDesign()));
    return database;
}

private BusinessActionDesign businessAction(String code)
{
    BusinessActionDesign action = new BusinessActionDesign();
    action.setCode(code);
    return action;
}

private BusinessLoopAuditResult completeAudit()
{
    BusinessLoopAuditResult result = new BusinessLoopAuditResult();
    result.setComplete(true);
    result.setLoopActions(1);
    result.setStateTransitions(1);
    result.setQuantityRules(1);
    result.setRecordRules(0);
    return result;
}
```

Add imports:

```java
import com.ruoyi.generator.domain.front.dto.BusinessLoopAuditResult;
import com.ruoyi.generator.domain.front.dto.BusinessLoopPlan;
import com.ruoyi.generator.domain.front.dto.GenerateBusinessLoopPlanRequest;
```

- [ ] **Step 2: Wire dependencies and stage calls**

In `OneClickProjectGenerationServiceImpl`, add:

```java
@Autowired
private BusinessLoopCoverageValidator businessLoopCoverageValidator;
```

After app-blueprint generation, add:

```java
updateStage(task, result, OneClickProjectGenerationResult.STAGE_BUSINESS_LOOP_PLAN, 25, "正在规划业务闭环");
BusinessLoopPlan businessLoopPlan = aiGenerateService.generateBusinessLoopPlan(task.getUserId(), task.getProjectId(),
        toBusinessLoopPlanRequest(request, appBlueprintJson));
String businessLoopPlanJson = JSON.toJSONString(businessLoopPlan);
```

Change database progress from `35` to `42` and pass the loop plan:

```java
DatabaseDesignResponse database = aiGenerateService.generateDatabase(task.getUserId(), task.getProjectId(),
        toDatabaseRequest(request, appBlueprintJson, businessLoopPlanJson));
```

After table count:

```java
updateStage(task, result, OneClickProjectGenerationResult.STAGE_DATABASE_LOOP_AUDIT, 48, "正在校验数据库是否覆盖业务闭环");
BusinessLoopAuditResult databaseAudit = businessLoopCoverageValidator.auditDatabase(businessLoopPlan, database);
applyLoopAudit(result, databaseAudit);
if (!databaseAudit.isComplete())
{
    throw auditFailure(result, OneClickProjectGenerationResult.STAGE_DATABASE_LOOP_AUDIT, databaseAudit);
}
```

Change business generation call:

```java
List<BusinessActionDesign> businessActions = aiGenerateService.generateBusinessBlueprint(task.getUserId(),
        task.getProjectId(), toBusinessBlueprintRequest(request, appBlueprintJson, businessLoopPlanJson));
```

After business action count:

```java
updateStage(task, result, OneClickProjectGenerationResult.STAGE_BUSINESS_LOOP_AUDIT, 58, "正在校验业务动作是否形成闭环");
BusinessLoopAuditResult actionAudit = businessLoopCoverageValidator.auditBusinessActions(businessLoopPlan, businessActions);
applyLoopAudit(result, actionAudit);
if (!actionAudit.isComplete())
{
    throw auditFailure(result, OneClickProjectGenerationResult.STAGE_BUSINESS_LOOP_AUDIT, actionAudit);
}
```

- [ ] **Step 3: Add request and audit helpers**

Add helpers:

```java
private GenerateBusinessLoopPlanRequest toBusinessLoopPlanRequest(AiGenerationTaskCreateRequest source, String appBlueprintJson)
{
    GenerateBusinessLoopPlanRequest request = new GenerateBusinessLoopPlanRequest();
    request.setProjectName(source.getProjectName());
    request.setProjectDesc(source.getProjectDesc());
    request.setIndustryTemplate(source.getIndustryTemplate());
    request.setExtraRequirements(source.getExtraRequirements());
    request.setAppBlueprint(appBlueprintJson);
    return request;
}

private GenerateDatabaseRequest toDatabaseRequest(AiGenerationTaskCreateRequest source, String appBlueprintJson,
        String businessLoopPlanJson)
{
    GenerateDatabaseRequest request = new GenerateDatabaseRequest();
    request.setProjectName(source.getProjectName());
    request.setProjectDesc(source.getProjectDesc());
    request.setIndustryTemplate(source.getIndustryTemplate());
    request.setExtraRequirements(source.getExtraRequirements());
    request.setAppBlueprint(appBlueprintJson);
    request.setBusinessLoopPlan(businessLoopPlanJson);
    return request;
}

private GenerateBusinessBlueprintRequest toBusinessBlueprintRequest(AiGenerationTaskCreateRequest source,
        String appBlueprintJson, String businessLoopPlanJson)
{
    GenerateBusinessBlueprintRequest request = new GenerateBusinessBlueprintRequest();
    request.setProjectName(source.getProjectName());
    request.setProjectDesc(source.getProjectDesc());
    request.setIndustryTemplate(source.getIndustryTemplate());
    request.setExtraRequirements(source.getExtraRequirements());
    request.setAppBlueprint(appBlueprintJson);
    request.setBusinessLoopPlan(businessLoopPlanJson);
    return request;
}

private void applyLoopAudit(OneClickProjectGenerationResult result, BusinessLoopAuditResult audit)
{
    if (audit == null || result.getReport() == null)
    {
        return;
    }
    result.getReport().setBusinessLoopComplete(audit.isComplete());
    result.getReport().setLoopActions(audit.getLoopActions());
    result.getReport().setStateTransitions(audit.getStateTransitions());
    result.getReport().setQuantityRules(audit.getQuantityRules());
    result.getReport().setRecordRules(audit.getRecordRules());
    result.getReport().setMissingRequiredActions(audit.getMissingRequiredActions());
}

private OneClickProjectGenerationException auditFailure(OneClickProjectGenerationResult result, String stage,
        BusinessLoopAuditResult audit)
{
    result.setFailedStage(stage);
    String message = audit == null || audit.getErrors() == null || audit.getErrors().isEmpty()
            ? "业务闭环不完整"
            : audit.getErrors().get(0);
    result.setErrorMessage(message);
    result.getSuggestedActions().add("进入专家模式查看业务闭环计划和缺失项后重新生成");
    return new OneClickProjectGenerationException(message, result, null);
}
```

Remove or replace the old two-argument `toDatabaseRequest` and `toBusinessBlueprintRequest` methods so there is no overload ambiguity.

- [ ] **Step 4: Update successful generation stubs**

In `stubSuccessfulGeneration`, add:

```java
BusinessLoopPlan loopPlan = loopPlan();
when(aiGenerateService.generateBusinessLoopPlan(eq(10L), eq(20L), any(GenerateBusinessLoopPlanRequest.class)))
        .thenReturn(loopPlan);
when(businessLoopCoverageValidator.auditDatabase(eq(loopPlan), any(DatabaseDesignResponse.class)))
        .thenReturn(completeAudit());
when(businessLoopCoverageValidator.auditBusinessActions(eq(loopPlan), any()))
        .thenReturn(completeAudit());
```

- [ ] **Step 5: Run one-click tests**

Run:

```powershell
mvn -q -pl ruoyi-generator -Dtest=OneClickProjectGenerationServiceImplTest test
```

Expected: one-click tests pass and verify the new business loop stages.

- [ ] **Step 6: Commit**

```powershell
git add -- ruoyi-generator/src/main/java/com/ruoyi/generator/service/front/OneClickProjectGenerationServiceImpl.java ruoyi-generator/src/test/java/com/ruoyi/generator/service/front/OneClickProjectGenerationServiceImplTest.java
git commit -m "Enforce business loop audit in one-click generation"
```

- Test: `ruoyi-generator/src/test/java/com/ruoyi/generator/service/front/OneClickProjectGenerationServiceImplTest.java`

- [ ] **Step 1: Add failing page binding test**

In `FrontendPageDesignServiceTest`, add:

```java
@Test
public void applyBusinessLoopBindingsAddsBusinessRowActions()
{
    FrontProjectPageDesign current = currentDesign();
    current.setActionJson("{\"toolbarActions\":[],\"rowActions\":[]}");
    when(frontProjectService.getProject(7L, 10L)).thenReturn(project());
    when(pageDesignMapper.selectDesignsByProjectIdAndScope(10L, "frontend"))
            .thenReturn(Collections.singletonList(current));
    when(frontProjectTableMapper.selectTablesByProjectId(10L)).thenReturn(Collections.singletonList(bookTable()));
    when(frontProjectColumnMapper.selectColumnsByTableId(99L)).thenReturn(Collections.singletonList(column("book_title", "bookTitle", "1", "1", "1")));

    service.applyBusinessLoopBindings(7L, 10L, bindingPlan(), "frontend");

    ArgumentCaptor<FrontProjectPageDesign> captor = ArgumentCaptor.forClass(FrontProjectPageDesign.class);
    verify(pageDesignMapper).updateFrontProjectPageDesign(captor.capture());
    assertTrue(captor.getValue().getActionJson().contains("business:borrow_book"));
}

private BusinessLoopPlan bindingPlan()

    BusinessLoopPlan plan = new BusinessLoopPlan();
    BusinessLoopPlan.BusinessLoopPageBinding binding = new BusinessLoopPlan.BusinessLoopPageBinding();
    binding.setActionCode("borrow_book");
    binding.setTarget("frontend");
    binding.setPageCode("book_catalog_page");
    binding.setTableName("book_info");
    binding.setSlot("list.rowActions");
    plan.getPageBindings().add(binding);
    return plan;
}
```

Add import:

```java
import com.ruoyi.generator.domain.front.dto.BusinessLoopPlan;
```

- [ ] **Step 2: Implement applyBusinessLoopBindings**

In `FrontendPageDesignService`, add public method:

```java
@Transactional

{
    frontProjectService.getProject(userId, projectId);
    String normalizedScope = normalizeScope(scope);

    Map<String, FrontProjectPageDesign> designsByPageCode = new LinkedHashMap<String, FrontProjectPageDesign>();
    for (FrontProjectPageDesign design : designs)
    {
        if (design != null && StringUtils.isNotEmpty(design.getPageCode()))
        {
            designsByPageCode.put(design.getPageCode(), design);
        }
    }
    Map<String, TableBundle> tablesByName = loadTables(projectId);
    for (BusinessLoopPlan.BusinessLoopPageBinding binding : safeLoopBindings(plan))
    {
        if (binding == null || !bindingTargetMatches(binding, normalizedScope))
        {
            continue;
        }
        FrontProjectPageDesign design = designsByPageCode.get(binding.getPageCode());
        if (design == null)
        {
            continue;
        }
        TableBundle table = StringUtils.isEmpty(design.getTableName()) ? null : tablesByName.get(design.getTableName());
        String actionJson = mergeBusinessActionBinding(design.getActionJson(), binding);
        design.setActionJson(normalizeAction(actionJson, table, normalizedScope));
        design.setVersion(design.getVersion() == null ? 2 : design.getVersion() + 1);
        pageDesignMapper.updateFrontProjectPageDesign(design);
    }
}
```

Add helpers:

```java
private List<BusinessLoopPlan.BusinessLoopPageBinding> safeLoopBindings(BusinessLoopPlan plan)
{
    return plan == null || plan.getPageBindings() == null
            ? new ArrayList<BusinessLoopPlan.BusinessLoopPageBinding>() : plan.getPageBindings();
}

private boolean bindingTargetMatches(BusinessLoopPlan.BusinessLoopPageBinding binding, String scope)
{
    String target = StringUtils.isEmpty(binding.getTarget()) ? FRONTEND_SCOPE : binding.getTarget();
    return normalizeScope(scope).equals(normalizeScope("admin_frontend".equals(target) ? ADMIN_SCOPE : target));
}

@SuppressWarnings("unchecked")
private String mergeBusinessActionBinding(String actionJson, BusinessLoopPlan.BusinessLoopPageBinding binding)
{
    Map<String, Object> action = StringUtils.isEmpty(actionJson)
            ? new LinkedHashMap<String, Object>()
            : readMap(actionJson, "页面按钮JSON格式错误");
    String key = "list.toolbarActions".equals(binding.getSlot()) ? "toolbarActions" : "rowActions";
    Object current = action.get(key);
    List<Object> actions = current instanceof List ? new ArrayList<Object>((List<Object>) current) : new ArrayList<Object>();
    String actionCode = "business:" + binding.getActionCode();
    for (Object item : actions)
    {
        if (item instanceof Map && actionCode.equals(stringValue(((Map<String, Object>) item).get("code"))))
        {
            return writeJson(action);
        }
        if (actionCode.equals(stringValue(item)))
        {
            return writeJson(action);
        }
    }
    Map<String, Object> item = new LinkedHashMap<String, Object>();
    item.put("code", actionCode);
    actions.add(item);
    action.put(key, actions);
    if (!action.containsKey("toolbarActions"))
    {
        action.put("toolbarActions", new ArrayList<Object>());
    }
    if (!action.containsKey("rowActions"))
    {
        action.put("rowActions", new ArrayList<Object>());
    }
    return writeJson(action);
}
```

Add import:

```java
import com.ruoyi.generator.domain.front.dto.BusinessLoopPlan;
```

- [ ] **Step 3: Wire one-click page binding**

In `OneClickProjectGenerationServiceImpl`, after each `initializePageDesigns` call, add:

```java
frontendPageDesignService.applyBusinessLoopBindings(task.getUserId(), task.getProjectId(), businessLoopPlan, "frontend");
```

for frontend, and:

```java
frontendPageDesignService.applyBusinessLoopBindings(task.getUserId(), task.getProjectId(), businessLoopPlan, "admin");
```

for admin.

Update `OneClickProjectGenerationServiceImplTest.generateRunsBusinessLoopPlanBeforeDatabaseAndAuditsCoverage` to verify:

```java
verify(frontendPageDesignService).applyBusinessLoopBindings(10L, 20L, loopPlan, "frontend");
verify(frontendPageDesignService).applyBusinessLoopBindings(10L, 20L, loopPlan, "admin");
```

- [ ] **Step 4: Run page binding tests**

Run:

```powershell
mvn -q -pl ruoyi-generator -Dtest=FrontendPageDesignServiceTest,OneClickProjectGenerationServiceImplTest test
```

Expected: page design and one-click tests pass.

- [ ] **Step 5: Commit**

```powershell
git add -- ruoyi-generator/src/main/java/com/ruoyi/generator/service/front/FrontendPageDesignService.java ruoyi-generator/src/main/java/com/ruoyi/generator/service/front/OneClickProjectGenerationServiceImpl.java ruoyi-generator/src/test/java/com/ruoyi/generator/service/front/FrontendPageDesignServiceTest.java ruoyi-generator/src/test/java/com/ruoyi/generator/service/front/OneClickProjectGenerationServiceImplTest.java
git commit -m "Bind business loop actions to generated pages"
```

### Task 6: Frontend Result Reporting

**Files:**
- Modify: `easycode-web/src/views/GenerateView.vue`
- Test: `easycode-web/src/views/generateView.test.mjs`

- [ ] **Step 1: Add failing source-level test**

In `generateView.test.mjs`, add:

```javascript
test('GenerateView shows business loop completion in one-click result', () => {
  assert.match(source, /businessLoopComplete/)
  assert.match(source, /loopActions/)
  assert.match(source, /missingRequiredActions/)
  assert.match(source, /业务闭环/)
})
```

- [ ] **Step 2: Render loop report fields**

In the one-click result card inside `GenerateView.vue`, after the existing `el-descriptions` block, add:

```vue
<el-descriptions v-if="oneClickResult.report" class="loop-report" :column="2" border>
  <el-descriptions-item label="业务闭环">
    {{ oneClickResult.report.businessLoopComplete ? '已完成' : '未完成' }}
  </el-descriptions-item>
  <el-descriptions-item label="闭环动作">
    {{ oneClickResult.report.loopActions || 0 }}
  </el-descriptions-item>
  <el-descriptions-item label="状态流转">
    {{ oneClickResult.report.stateTransitions || 0 }}
  </el-descriptions-item>
  <el-descriptions-item label="数量规则">
    {{ oneClickResult.report.quantityRules || 0 }}
  </el-descriptions-item>
</el-descriptions>
<el-alert
  v-if="oneClickResult.report?.missingRequiredActions?.length"
  type="warning"
  :title="`缺少业务动作：${oneClickResult.report.missingRequiredActions.join('、')}`"
  show-icon
  :closable="false"
/>
```

Add style:

```scss
.loop-report {
  margin-top: 14px;
}
```

- [ ] **Step 3: Run frontend test**

Run:

```powershell
cd easycode-web
node --test src/views/generateView.test.mjs
```

Expected: `generateView.test.mjs` passes.

- [ ] **Step 4: Commit**

```powershell
git add -- easycode-web/src/views/GenerateView.vue easycode-web/src/views/generateView.test.mjs
git commit -m "Show business loop report in one-click UI"
```

---

### Task 7: Verification and Regression Sweep

**Files:**
- All files modified by Tasks 1-6.

- [ ] **Step 1: Run focused backend tests**

```powershell
mvn -q -pl ruoyi-generator -Dtest=BusinessLoopPlanValidatorTest,BusinessLoopCoverageValidatorTest,AiGenerateServiceImplTest,OneClickProjectGenerationServiceImplTest,FrontendPageDesignServiceTest test
```

Expected: all focused backend tests pass.

- [ ] **Step 2: Run generator module tests**

```powershell
mvn -q -pl ruoyi-generator test
```

Expected: generator module tests pass.

- [ ] **Step 3: Run frontend source-level tests**

```powershell
cd easycode-web
node --test src/views/generateView.test.mjs src/views/previewView.test.mjs src/components/frontendPageDesigner.test.mjs
```

Expected: listed frontend tests pass.

- [ ] **Step 4: Run frontend build**

```powershell
cd easycode-web
npm run build
```

Expected: Vite build completes successfully.

- [ ] **Step 5: Run diff checks**

```powershell
git diff --check
git status --short
```

Expected: `git diff --check` prints no errors. `git status --short` shows only intentional files from this implementation plus pre-existing unrelated workspace changes.

- [ ] **Step 6: Manual smoke test**

1. Start backend and frontend using the repo's normal local workflow.
2. Log in to EasyCode frontend.
3. Open the generation page.
4. Enter `图书借阅系统` as project name and leave description empty.
5. Click `生成完整项目`.
6. Confirm task progress includes business loop planning and loop audit stages.
7. Confirm success report shows business loop complete.
8. Open generated user frontend and confirm a book list or detail page has a borrow action.
9. Open generated admin frontend and confirm the borrow record page has a confirmation or status action.
10. Download source and confirm generated backend contains business action controller/service methods.

- [ ] **Step 7: Final commit if verification required fixes**

If verification fixes were made after Task 6, commit only those fixes:

```powershell
git add -- <fixed-files>
git commit -m "Stabilize business loop generation"
```

## Acceptance Criteria

- A one-click task generates a structured `BusinessLoopPlan` after app-blueprint generation.
- Database and business-action prompts receive the same loop-plan JSON.
- Database generation is audited for required status fields, quantity fields, and record tables.
- Business-action generation is audited for required actions and required effects.
- A one-click task fails clearly when the loop is incomplete instead of silently succeeding as CRUD.
- Generated page designs receive business action buttons from loop page bindings.
- The one-click UI shows loop completion, action count, transition count, quantity rule count, and missing required actions.
- Focused backend tests, generator module tests, frontend source-level tests, and frontend build pass.
