+# 数字货币发行请求模块 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 the first-step digital-currency issuance workflow with separate commercial-bank and central-bank APIs, real SM3/SM2 teaching operations, and Chinese Swagger documentation.
+
+**Architecture:** Extend the existing `issuance` bounded context around one `IssuanceRequest` aggregate. Commercial-bank APIs own request creation and state transitions; central-bank APIs are a read-only projection of the same request, with a separate receive-status field. MyBatis-Plus persists the aggregate and denomination children; `schema.sql` remains the only idempotent database bootstrap mechanism.
+
+**Tech Stack:** Java 8, Spring Boot 2.7.18, Spring Security 5.7, MyBatis-Plus 3.5.17, Springdoc 1.8.0, MySQL 8, Bouncy Castle `bcprov-jdk18on:1.84`.
+
+## Global Constraints
+
+- Use Java 8 only; do not introduce records, `List.of`, text blocks, `jakarta.*`, or Java 9+ APIs.
+- Keep all issuance code below `com.yau.digitalrmb.issuance`; do not place issuance business code in `shared`.
+- All commercial-bank and central-bank APIs require a valid JWT, with no teacher/student role restriction.
+- Do not restore Flyway. Schema and demo data changes belong in the idempotent `src/main/resources/schema.sql` and must work on MySQL 8 and H2 MySQL mode.
+- Do not accept, log, persist, or return a private key. The only exposed signing-key identifier is `sm2-key-02`.
+- Swagger labels, summaries, descriptions, field documentation, and root title must be Chinese UTF-8 without garbled characters.
+- All work starts from a clean isolated worktree and ends with JDK 8 `mvn test -B`, `mvn package -DskipTests -B`, dev-profile startup, `/actuator/health`, `/v3/api-docs`, and Swagger UI verification.

+## Task 1: Model the Issuance Request Aggregate
+
+**Files:**
+- Create: `src/main/java/com/yau/digitalrmb/issuance/domain/model/DenominationItem.java`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/domain/model/IssuanceRequest.java`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/domain/model/IssuanceRequestStatus.java`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/domain/model/CentralBankReceiveStatus.java`
+- Create: `src/test/java/com/yau/digitalrmb/issuance/domain/model/IssuanceRequestTest.java`
+
+**Interfaces:**
+- Consumes: existing `IssuanceApplicationId`.
+- Produces: aggregate methods `updateDraft(...)`, `prepareMessage(...)`, `recordDigest(...)`, `recordSignature(...)`, `packagePayload(...)`, and `sendToCentralBank(Instant)`.
+
+- [ ] **Step 1: Write failing aggregate tests**
+
+```java
+@Test
+void rejectsDenominationsWhoseTotalDoesNotMatchRequestAmount() {
+    assertThatThrownBy(() -> IssuanceRequest.create(id, "BKCHCNBJ00001", "ORG_3A4B5C6D7E8F",
+            new BigDecimal("50000.00"), "DC", Arrays.asList(new DenominationItem(100, 400))))
+        .isInstanceOf(IllegalArgumentException.class);
+}
+
+@Test
+void sendsOnlyPackagedRequestAndMarksCentralBankAsReceived() {
+    IssuanceRequest request = preparedSignedAndPackagedRequest();
+    request.sendToCentralBank(Instant.parse("2026-08-03T12:00:00Z"));
+    assertThat(request.getStatus()).isEqualTo(IssuanceRequestStatus.SENT);
+    assertThat(request.getCentralBankReceiveStatus()).isEqualTo(CentralBankReceiveStatus.RECEIVED);
+}
+```
+
+- [ ] **Step 2: Run the aggregate test to verify it fails**
+
+Run: `mvn -Dtest=IssuanceRequestTest test -B`
+
+Expected: compilation fails because `IssuanceRequest`, status enums, and `DenominationItem` do not yet exist.
+
+- [ ] **Step 3: Implement immutable value data and aggregate transitions**
+
+```java
+public enum IssuanceRequestStatus { DRAFT, MESSAGE_PREPARED, DIGESTED, SIGNED, PACKAGED, SENT }
+public enum CentralBankReceiveStatus { NOT_RECEIVED, RECEIVED }
+
+public void sendToCentralBank(Instant receivedAt) {
+    requireStatus(IssuanceRequestStatus.PACKAGED);
+    this.status = IssuanceRequestStatus.SENT;
+    this.centralBankReceiveStatus = CentralBankReceiveStatus.RECEIVED;
+    this.centralBankReceivedAt = receivedAt;
+}
+```
+
+`DenominationItem` validates positive denomination and quantity. `IssuanceRequest.create(...)` validates exact `Σ(denomination × quantity) == totalAmount`, initializes `DRAFT` and `NOT_RECEIVED`, and normalizes monetary values to scale 2.
+
+- [ ] **Step 4: Run aggregate tests to verify they pass**
+
+Run: `mvn -Dtest=IssuanceRequestTest test -B`
+
+Expected: PASS, including invalid amount, invalid state, normal state progression, and idempotent repeated send tests.
+
+- [ ] **Step 5: Commit the aggregate model**
+
+```bash
+git add src/main/java/com/yau/digitalrmb/issuance/domain/model src/test/java/com/yau/digitalrmb/issuance/domain/model/IssuanceRequestTest.java
+git commit -m "feat: add issuance request aggregate"
+```
+
+## Task 2: Implement SM3 and SM2 Teaching Services
+
+**Files:**
+- Modify: `pom.xml`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/domain/service/IssuanceMessageComposer.java`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/domain/service/IssuanceSignatureService.java`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/domain/service/SignedIssuancePayload.java`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/infrastructure/crypto/InMemorySm2SigningKeyProvider.java`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/infrastructure/crypto/BouncyCastleIssuanceSignatureService.java`
+- Create: `src/test/java/com/yau/digitalrmb/issuance/infrastructure/crypto/BouncyCastleIssuanceSignatureServiceTest.java`
+
+**Interfaces:**
+- Consumes: `IssuanceRequest` field values and fixed key reference `sm2-key-02`.
+- Produces: `compose(...)` plain text and `sign(String keyRef, String plainText)` returning a SM3 hex digest plus Base64 SM2 signature.
+
+- [ ] **Step 1: Write failing cryptography tests**
+
+```java
+@Test
+void composesPrototypeCompatiblePlainTextInDescendingDenominationOrder() {
+    assertThat(composer.compose("BKCHCNBJ00001", "ORG_3A4B5C6D7E8F", new BigDecimal("50000.00"),
+            Arrays.asList(new DenominationItem(50, 100), new DenominationItem(100, 400)), "DC", "20260801103218"))
+        .isEqualTo("ISSUE|BKCHCNBJ00001|ORG_3A4B5C6D7E8F|50000.00|100:400,50:100|DC|20260801103218");
+}
+
+@Test
+void signsWithSm3AndSm2UsingTheTeachingKey() {
+    SignedIssuancePayload payload = service.sign("sm2-key-02", "ISSUE|...");
+    assertThat(payload.getDigest()).matches("[0-9A-F]{64}");
+    assertThat(service.verify("sm2-key-02", "ISSUE|...", payload)).isTrue();
+}
+```
+
+- [ ] **Step 2: Run the cryptography tests to verify they fail**
+
+Run: `mvn -Dtest=BouncyCastleIssuanceSignatureServiceTest test -B`
+
+Expected: compilation fails because the composer, payload, signing service, and Bouncy Castle provider are absent.
+
+- [ ] **Step 3: Add the provider and minimal implementations**
+
+Add the explicit dependency:
+
+```xml
+<dependency>
+  <groupId>org.bouncycastle</groupId>
+  <artifactId>bcprov-jdk18on</artifactId>
+  <version>1.84</version>
+</dependency>
+```
+
+Register `BouncyCastleProvider` once. Generate an in-memory `sm2p256v1` key pair for `sm2-key-02`; use `MessageDigest.getInstance("SM3", "BC")` for the upper-case hexadecimal digest and `Signature.getInstance("SM3withSM2", "BC")` for signing and verification. The `IssuanceMessageComposer` sorts denominations descending and uses `toPlainString()` for the scale-2 total amount.
+
+- [ ] **Step 4: Run the cryptography tests to verify they pass**
+
+Run: `mvn -Dtest=BouncyCastleIssuanceSignatureServiceTest test -B`
+
+Expected: PASS; the digest has 64 uppercase hexadecimal characters and the generated signature verifies with the in-memory public key.
+
+- [ ] **Step 5: Commit the cryptography teaching service**
+
+```bash
+git add pom.xml src/main/java/com/yau/digitalrmb/issuance/domain/service src/main/java/com/yau/digitalrmb/issuance/infrastructure/crypto src/test/java/com/yau/digitalrmb/issuance/infrastructure/crypto
+git commit -m "feat: add issuance sm3 sm2 teaching service"
+```
+
+## Task 3: Add Idempotent Schema and MyBatis Persistence
+
+**Files:**
+- Modify: `src/main/resources/schema.sql`
+- Create: `src/main/java/com/yau/digitalrmb/issuance/domain/repository/IssuanceRequestRepository.java`
+- Create: the six entity, mapper, and repository files listed in Target File Structure under `infrastructure/persistence`
+- Create: `src/test/java/com/yau/digitalrmb/issuance/infrastructure/persistence/MybatisIssuanceRequestRepositoryTest.java`
+
+**Interfaces:**
+- Consumes: `IssuanceRequestRepository.save(IssuanceRequest)` and `findById(IssuanceApplicationId)`.
+- Produces: persistent requests with all denomination entries and persistent commercial-bank inventory lookups.
+
+- [ ] **Step 1: Write failing persistence tests**
+
+```java
+@Test
+void savesAndRestoresTheRequestWithItsDenominationsAndCentralBankStatus() {
+    repository.save(sentRequest);
+    IssuanceRequest restored = repository.findById(sentRequest.getId()).get();
+    assertThat(restored.getDenominations()).containsExactly(new DenominationItem(100, 400), new DenominationItem(50, 100));
+    assertThat(restored.getCentralBankReceiveStatus()).isEqualTo(CentralBankReceiveStatus.RECEIVED);
+}
+
+@Test
+void readsSuggestedAmountAsThresholdMinusCurrentBalance() {
+    assertThat(inventoryQuery.findByBankCode("BKCHCNBJ00001").getSuggestedSupplementAmount())
+        .isEqualByComparingTo("50000.00");
+}
+```
+
+- [ ] **Step 2: Run persistence tests to verify they fail**
+
+Run: `mvn -Dtest=MybatisIssuanceRequestRepositoryTest test -B`
+
+Expected: compilation fails because the repository and mappers do not exist.
+
+- [ ] **Step 3: Add schema and persistence mapping**
+
+Append idempotent MySQL/H2-compatible DDL to `schema.sql`:
+
+```sql
+CREATE TABLE IF NOT EXISTS issuance_bank_inventory (
+  bank_code VARCHAR(32) PRIMARY KEY,
+  current_balance DECIMAL(20, 2) NOT NULL,
+  warning_threshold DECIMAL(20, 2) NOT NULL,
+  updated_at TIMESTAMP NOT NULL
+);
+
+CREATE TABLE IF NOT EXISTS issuance_request (
+  id CHAR(36) PRIMARY KEY,
+  request_no VARCHAR(64) NOT NULL UNIQUE,
+  bank_code VARCHAR(32) NOT NULL,
+  organization_id VARCHAR(64) NOT NULL,
+  total_amount DECIMAL(20, 2) NOT NULL,
+  currency VARCHAR(16) NOT NULL,
+  request_timestamp VARCHAR(32),
+  message_text TEXT,
+  digest CHAR(64),
+  signature TEXT,
+  signing_key_ref VARCHAR(64),
+  payload_json TEXT,
+  status VARCHAR(32) NOT NULL,
+  central_receive_status VARCHAR(32) NOT NULL,
+  central_received_at TIMESTAMP NULL,
+  created_at TIMESTAMP NOT NULL,
+  updated_at TIMESTAMP NOT NULL,
+  created_by VARCHAR(64) NOT NULL,
+  updated_by VARCHAR(64) NOT NULL,
+  deleted BOOLEAN NOT NULL DEFAULT FALSE
+);
+
+CREATE TABLE IF NOT EXISTS issuance_request_denomination (
+  request_id CHAR(36) NOT NULL,
+  denomination INT NOT NULL,
+  quantity INT NOT NULL,
+  PRIMARY KEY (request_id, denomination)
+);
+```
+
+Seed `BKCHCNBJ00001` with `49950000.00` balance and `50000000.00` threshold using an idempotent upsert. Map the root row and denomination rows in the repository; replacing denomination rows occurs only inside a repository save transaction.
+
+- [ ] **Step 4: Run persistence tests to verify they pass**
+
+Run: `mvn -Dtest=MybatisIssuanceRequestRepositoryTest test -B`
+
+Expected: PASS against the existing H2 MySQL-mode test profile.
+
+- [ ] **Step 5: Commit schema and persistence**
+
+```bash
+git add src/main/resources/schema.sql src/main/java/com/yau/digitalrmb/issuance/domain/repository src/main/java/com/yau/digitalrmb/issuance/infrastructure/persistence src/test/java/com/yau/digitalrmb/issuance/infrastructure/persistence
+git commit -m "feat: persist issuance requests and bank inventory"
+```
+
+## Task 4: Add Commercial-Bank and Central-Bank Application Services
+
+**Files:**
+- Create: all command, query, and application-service files listed in Target File Structure
+- Create: `src/test/java/com/yau/digitalrmb/issuance/application/service/CommercialBankIssuanceApplicationServiceTest.java`
+- Create: `src/test/java/com/yau/digitalrmb/issuance/application/service/CentralBankIssuanceQueryServiceTest.java`
+
+**Interfaces:**
+- Consumes: domain aggregate, repository, message composer, signing service, and authenticated account name.
+- Produces: `create`, `update`, `prepareMessage`, `digest`, `sign`, `packagePayload`, `send`, `getCommercialBankView`, `getInventory`, and `getCentralBankView` application methods.
+
+- [ ] **Step 1: Write failing application-service tests**
+
+```java
+@Test
+void processesACommercialBankRequestThroughSendAndMakesItVisibleToCentralBank() {
+    UUID id = service.create(createCommand, "tzs001").getId();
+    service.prepareMessage(id, "tzs001");
+    service.digest(id, "tzs001");
+    service.sign(id, "tzs001");
+    service.packagePayload(id, "tzs001");
+    service.send(id, "tzs001");
+    assertThat(centralBankService.get(id).getReceiveStatus()).isEqualTo("RECEIVED");
+}
+
+@Test
+void rejectsUpdateAfterMessagePreparation() {
+    UUID id = createAndPrepareRequest();
+    assertThatThrownBy(() -> service.update(id, changedCommand, "tzs001"))
+        .isInstanceOf(BusinessException.class);
+}
+```
+
+- [ ] **Step 2: Run application-service tests to verify they fail**
+
+Run: `mvn -Dtest=CommercialBankIssuanceApplicationServiceTest,CentralBankIssuanceQueryServiceTest test -B`
+
+Expected: compilation fails because the command, query, and application services do not exist.
+
+- [ ] **Step 3: Implement application orchestration and error mapping**
+
+Generate request numbers using `ISSUE_REQ_` plus a UUID-derived upper-case suffix. Wrap writes in `@Transactional`; read inventory and central-bank data with dedicated query methods. Convert missing aggregate lookups into `BusinessException(ErrorCode.RESOURCE_NOT_FOUND, ...)`; convert domain `IllegalStateException` and `IllegalArgumentException` into `BusinessException(ErrorCode.VALIDATION_ERROR, ...)`. Make `send` return the existing `SENT` result when called again.
+
+- [ ] **Step 4: Run application-service tests to verify they pass**
+
+Run: `mvn -Dtest=CommercialBankIssuanceApplicationServiceTest,CentralBankIssuanceQueryServiceTest test -B`
+
+Expected: PASS; a commercial-bank send produces a central-bank `RECEIVED` view and draft editing is rejected after preparation.
+
+- [ ] **Step 5: Commit application services**
+
+```bash
+git add src/main/java/com/yau/digitalrmb/issuance/application src/test/java/com/yau/digitalrmb/issuance/application
+git commit -m "feat: add issuance application workflow"
+```
+
+## Task 5: Expose Separate Chinese-Swagger REST Ends
+
+**Files:**
+- Create: all DTO and controller files listed in Target File Structure
+- Modify: `src/main/java/com/yau/digitalrmb/shared/config/OpenApiConfig.java`
+- Create: `src/test/java/com/yau/digitalrmb/issuance/interfaces/rest/CommercialBankIssuanceControllerTest.java`
+- Create: `src/test/java/com/yau/digitalrmb/issuance/interfaces/rest/CentralBankIssuanceControllerTest.java`
+
+**Interfaces:**
+- Consumes: application service methods and current authenticated JWT subject.
+- Produces: the ten REST paths specified in the approved design, wrapped in `ApiResponse<T>`.
+
+- [ ] **Step 1: Write failing MVC and OpenAPI documentation tests**
+
+```java
+@Test
+void commercialBankCreateRequiresJwtAndReturnsDraftRequest() throws Exception {
+    mockMvc.perform(post("/api/v1/commercial-banks/issuance/requests")
+            .with(jwt().jwt(jwt -> jwt.subject("tzs001")))
+            .contentType(MediaType.APPLICATION_JSON)
+            .content(validCreateBody))
+        .andExpect(status().isOk())
+        .andExpect(jsonPath("$.data.status").value("DRAFT"));
+}
+
+@Test
+void apiDocsContainChineseCommercialAndCentralBankTags() throws Exception {
+    mockMvc.perform(get("/v3/api-docs"))
+        .andExpect(status().isOk())
+        .andExpect(content().string(containsString("数字货币发行模块 - 商业银行端")))
+        .andExpect(content().string(containsString("数字货币发行模块 - 中央银行端")));
+}
+```
+
+- [ ] **Step 2: Run controller tests to verify they fail**
+
+Run: `mvn -Dtest=CommercialBankIssuanceControllerTest,CentralBankIssuanceControllerTest test -B`
+
+Expected: compilation fails because the controllers and DTOs do not exist.
+
+- [ ] **Step 3: Implement controllers, DTO validation, and Chinese Swagger metadata**
+
+Use the two class-level tags and paths exactly:
+
+```java
+@Tag(name = "数字货币发行模块 - 商业银行端", description = "商业银行发起和处理数字货币发行申请")
+@RequestMapping("/api/v1/commercial-banks/issuance")
+
+@Tag(name = "数字货币发行模块 - 中央银行端", description = "中央银行查看数字货币发行请求接收结果")
+@RequestMapping("/api/v1/central-banks/issuance")
+```
+
+Annotate each endpoint with Chinese `@Operation(summary = ..., description = ...)` and each DTO property with Chinese `@Schema(description = ..., example = ...)`. Set the root OpenAPI title to `数字人民币教学仿真后端` using UTF-8 source text. Commercial-bank controllers expose inventory, CRUD-read/update, process actions, and send; the central-bank controller exposes only `GET /requests/{id}`.
+
+- [ ] **Step 4: Run controller tests to verify they pass**
+
+Run: `mvn -Dtest=CommercialBankIssuanceControllerTest,CentralBankIssuanceControllerTest test -B`
+
+Expected: PASS; all commercial-bank write operations require JWT, central-bank query is isolated to its prefix, and `/v3/api-docs` has both readable Chinese tags.
+
+- [ ] **Step 5: Commit REST and Swagger work**
+
+```bash
+git add src/main/java/com/yau/digitalrmb/issuance/interfaces src/main/java/com/yau/digitalrmb/shared/config/OpenApiConfig.java src/test/java/com/yau/digitalrmb/issuance/interfaces
+git commit -m "feat: expose commercial and central issuance APIs"
+```
+
+## Task 6: Verify the Full Workflow on the Dev Database
+
+**Files:**
+- Modify: `README.md`
+- Test: existing and new `src/test/java/com/yau/digitalrmb/issuance/**` tests
+
+**Interfaces:**
+- Consumes: completed application JAR and `dev` profile.
+- Produces: documented startup and verified commercial-bank-to-central-bank workflow.
+
+- [ ] **Step 1: Write a failing integration workflow test**
+
+```java
+@Test
+void completeTeachingWorkflowReturnsReceivedPayloadToCentralBankEnd() throws Exception {
+    UUID requestId = createPrepareDigestSignPackageAndSendThroughCommercialBankApi();
+    mockMvc.perform(get("/api/v1/central-banks/issuance/requests/{id}", requestId)
+            .with(jwt().jwt(jwt -> jwt.subject("tzs001"))))
+        .andExpect(status().isOk())
+        .andExpect(jsonPath("$.data.receiveStatus").value("RECEIVED"))
+        .andExpect(jsonPath("$.data.payload.requestId").exists());
+}
+```
+
+- [ ] **Step 2: Run the full workflow test to verify it fails before the missing integration behavior is completed**
+
+Run: `mvn -Dtest=IssuanceWorkflowIntegrationTest test -B`
+
+Expected: FAIL until all commercial-bank action endpoints and the central-bank projection are connected.
+
+- [ ] **Step 3: Add only the missing integration wiring and document the dev workflow**
+
+Add a README section with the `dev` profile startup command, the Chinese Swagger URL, the commercial-bank inventory endpoint, and the central-bank request query endpoint. Do not document or expose any database password or private key.
+
+- [ ] **Step 4: Run all automated verification**
+
+Run:
+
+```powershell
+$env:JAVA_HOME='C:\Users\Acer\.jdks\temurin-8\jdk8u502-b07'
+$env:Path="$env:JAVA_HOME\bin;$env:Path"
+mvn test -B
+mvn package -DskipTests -B
+```
+
+Expected: Maven exits 0 with all tests passing and the JAR built for Java 8.
+
+- [ ] **Step 5: Run the dev-profile smoke test against the 118 test database**
+
+Run:
+
+```powershell
+java -jar target\digital-rmb-backend-0.0.1-SNAPSHOT.jar --spring.profiles.active=dev --server.port=8081
+Invoke-RestMethod http://localhost:8081/actuator/health
+Invoke-WebRequest http://localhost:8081/swagger-ui/index.html -UseBasicParsing
+Invoke-WebRequest http://localhost:8081/v3/api-docs -UseBasicParsing
+```
+
+Expected: health status is `UP`, Swagger returns HTTP 200, and OpenAPI JSON contains both readable Chinese tag names without replacement characters.
+
+- [ ] **Step 6: Commit verification and documentation**
+
+```bash
+git add README.md src/test/java/com/yau/digitalrmb/issuance/interfaces/rest/IssuanceWorkflowIntegrationTest.java
+git commit -m "test: verify issuance teaching workflow"
+```
+
+## Plan Self-Review
+
+- Spec coverage: Tasks 1–4 implement the aggregate, two-end state separation, inventory, persistence, message construction, SM3/SM2, and send simulation. Task 5 implements all approved API paths and Chinese Swagger grouping. Task 6 covers full workflow, JDK 8 build, dev database startup, and non-garbled OpenAPI verification.
+- Placeholder scan: no tasks defer behavior; each has concrete paths, interfaces, test commands, expected results, and implementation details.
+- Type consistency: all request IDs are UUID-backed `IssuanceApplicationId`; persistence and HTTP boundaries expose UUID values, while application services accept UUID and adapt to the value object internally. The status names are consistently `DRAFT`, `MESSAGE_PREPARED`, `DIGESTED`, `SIGNED`, `PACKAGED`, `SENT`, `NOT_RECEIVED`, and `RECEIVED`.
+
+## Execution Handoff
+
+Plan complete and saved to `docs/superpowers/plans/2026-08-03-issuance-request-implementation.md`.
+
+1. **Subagent-Driven (recommended)** — dispatch a fresh subagent per task and review between tasks.
+2. **Inline Execution** — execute tasks in this session in batches with review checkpoints.

+# Current User Context Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.
+
+**Goal:** Add no-argument current-user access for backend code and return the same complete profile from GET /api/v1/auth/me.
+
+**Architecture:** PlatformTokenVerifier parses verified profile claims into VerifiedPlatformToken. LocalSsoAccountService saves the profile in platform_user_snapshot. CurrentUserService reads that snapshot from the Jwt in SecurityContext, and AuthController delegates to it.
+
+**Tech Stack:** Java 8, Spring Boot 2.7, Spring Security, MyBatis-Plus, H2, JUnit 5, MockMvc.
+
+## Global Constraints

+# Local Token SSO Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace database-coupled platform SSO with shared-secret JWT verification, local user/password synchronization, and direct system-JWT redirect.
+
+**Architecture:** The SSO boundary verifies a three-segment HS256 parent JWT with a configured shared secret and produces validated claims. A transactional local account service finds or creates `sys_user` by `userId`, synchronizes the profile, role, and BCrypt password hash, then the controller issues the existing system JWT and redirects it to the frontend. No runtime component connects to or queries a platform database.
+
+**Tech Stack:** Java 8, Spring Boot 2.7.18, Spring Security OAuth2 JOSE/Nimbus, MyBatis-Plus, H2 test profile, BCrypt.
+
+## Global Constraints
+
+- Never connect to, query, or synchronize from the main platform database.
+- Verify the parent JWT with `platform-integration.token.link-secret-key`; never log or commit the shared secret, parent token, or password claim.
+- Require parent claims `userId`, `username`, `password`, and `roleid`.
+- Use `sys_user.id = userId`; map `roleid == 3` to `TEACHER`, all other values to `STUDENT`.
+- Every valid SSO login overwrites the local password hash with BCrypt of the parent `password` claim.
+- The application has one local datasource and `spring.datasource.hikari.minimum-idle: 2`.
+
+---
+
+## Task 1: Verify the parent Token without a platform repository
+
+**Files:**
+- Modify: `src/main/java/com/yau/digitalrmb/platformintegration/config/PlatformIntegrationProperties.java`

+
+**Interfaces:**
+- Produces `VerifiedPlatformToken verify(String rawToken)` with `userId()`, `username()`, `displayName()`, `rawPassword()`, `roleKey()`, and `optionalClaims()`.
+
+- [ ] **Step 1: Write failing verifier tests.**
+
+```java
+@Test
+void acceptsSignedParentTokenWithoutDatabaseLookup() {
+    VerifiedPlatformToken token = verifier.verify(parentToken(claims(
+        "userId", 487L, "username", "tzs001", "password", "new-password", "roleid", 2L)));

+    assertThatThrownBy(() -> verifier.verify(parentToken(claims("userId", 487L))))
+        .isInstanceOf(PlatformTokenException.class);
+}
+```
+
+- [ ] **Step 2: Run the verifier test to prove the old four-segment, repository-backed verifier fails.**
+
+Run: `mvn -B -Dtest=PlatformTokenVerifierTest test`
+
+Expected: FAIL because the old verifier requires `PlatformIdentityRepository`.
+
+- [ ] **Step 3: Implement the minimal shared-secret verifier.**
+
+Use the already available Spring Security JOSE support with a `SecretKeySpec(linkSecretKey.getBytes(UTF_8), "HmacSHA256")` to decode an HS256 JWT and validate its standard expiration. Reject blank or missing `userId`, `username`, `password`, or non-numeric `roleid`. Set `roleKey` to `TEACHER` only for `roleid == 3`; retain raw password only in-process and exclude it from logs, exceptions, and responses. Replace the old `Token` properties with:
+
+```java
+public static class Token {
+    @NotBlank
+    private String linkSecretKey;
+}
+```
+
+- [ ] **Step 4: Run the verifier tests and commit.**
+
+Run: `mvn -B -Dtest=PlatformTokenVerifierTest test`
+
+Expected: PASS with no repository mock or platform datasource fixture.

+
+- [ ] **Step 1: Write failing account synchronization tests.**
+

+    LocalSsoAccount account = service.synchronize(studentToken(487L, "tzs001", "first-password"));

+- [ ] **Step 2: Run the new test to prove it fails.**
+
+Run: `mvn -B -Dtest=LocalSsoAccountServiceTest test`
+
+Expected: FAIL because `LocalSsoAccountService` does not exist.
+
+- [ ] **Step 3: Implement the transactional local synchronizer.**
+
+Within one `@Transactional` method, load `sys_user` by `token.userId()`, create it with that ID when absent, and otherwise update it. In both branches set username, enabled status, and `passwordHash = passwordEncoder.encode(token.rawPassword())`. Upsert `platform_user_snapshot` from non-sensitive claims. Delete that user's `sys_user_role` rows and insert role ID `1001` for teachers or `1002` for students. Do not inject a named or secondary datasource.
+
+- [ ] **Step 4: Run the test and commit.**
+
+Run: `mvn -B -Dtest=LocalSsoAccountServiceTest test`

+
+- [ ] **Step 2: Run controller tests to prove the old exchange-code redirect fails.**
+
+Run: `mvn -B -Dtest=PlatformSsoControllerTest,AuthControllerTest test`
+
+Expected: FAIL because the old `Location` has `code=`.
+
+- [ ] **Step 3: Implement direct SSO redirect.**
+
+Verify the parent Token, synchronize the local account, issue the existing system JWT for the local ID and one role, URL-encode that system JWT, and redirect to `frontend.callback-url` with query key `token`. Preserve `Cache-Control: no-store` and `Referrer-Policy: no-referrer`. Remove `/session/exchange`; preserve `/login`, `/me`, and `/logout`.
+
+- [ ] **Step 4: Run controller tests and commit.**
+
+Run: `mvn -B -Dtest=PlatformSsoControllerTest,AuthControllerTest test`

Retain `platform_user_snapshot` and `auth_login_exchange_code` tables to avoid destructive database migration, but remove executable references to exchange codes. Configure only `platform-integration.token.link-secret-key: ${DIGITAL_RMB_PLATFORM_LINK_SECRET_KEY}` and `platform-integration.frontend.callback-url`; set the primary Hikari `minimum-idle` to `2`.

+# 数字货币发行请求模块设计
+
+## 目标
+
+实现“①发送数字货币发行请求”教学页面的后端。学生携带有效的本系统 JWT 后，可以在商业银行端查询库存、创建并逐步处理发行申请，并在中央银行端查看接收结果。接口不区分教师与学生角色。
+
+## 范围
+
+本期仅覆盖页面的第 1 步：商业银行生成并发送发行请求，以及中央银行显示已接收的请求。两个端是独立的接口入口和查询视图，但属于同一教学系统并共享发行申请数据。第 2 至第 7 步（验签、业务核查、准备金扣减、数字货币生成、确权）不在本期实现范围内。
+
+## 限界上下文与分层
+
+扩展既有 `issuance` 限界上下文，不新增顶层模块。`IssuanceRequest` 是聚合根；库存查询是该上下文的只读查询模型。
+
+```text
+issuance/
+  domain/
+    model/        IssuanceRequest、IssuanceApplicationId、DenominationItem、IssuanceRequestStatus
+    repository/   IssuanceRequestRepository
+    service/      IssuanceMessageComposer、IssuanceSignatureService
+  application/
+    command/      CreateIssuanceRequestCommand、UpdateDenominationsCommand
+    query/        IssuanceInventoryQueryService、IssuanceRequestQueryService
+    service/      IssuanceRequestApplicationService
+  infrastructure/
+    persistence/  MyBatis-Plus Entity、Mapper、Repository 实现
+    crypto/       Bouncy Castle 的 SM3/SM2 实验实现
+  interfaces/
+    rest/         CommercialBankIssuanceController、CentralBankIssuanceController
+    dto/          请求与响应 DTO
+```
+
+依赖方向保持 `interfaces → application → domain`，`infrastructure` 只实现领域端口。Controller 不直接调用 Mapper。
+
+## 聚合与状态机
+
+`IssuanceRequest` 保存机构代码、机构标识、发行金额、面额明细、币种、时间戳、待签名原文、摘要、签名、签名密钥标识、请求报文和当前状态。
+
+商业银行申请状态只能按下列顺序变化：
+
+```text
+DRAFT → MESSAGE_PREPARED → DIGESTED → SIGNED → PACKAGED → SENT
+```
+
+中央银行接收状态独立保存：
+
+```text
+NOT_RECEIVED → RECEIVED
+```
+
+- 只有 `DRAFT` 可修改总金额、面额明细和币种。
+- 面额数量必须为正整数，`Σ(面额 × 数量)` 必须等于发行总金额。
+- `prepare-message` 只允许从 `DRAFT` 执行，并冻结时间戳和待签名原文。
+- `digest`、`sign`、`package` 只允许在前一状态执行。
+- `send` 从 `PACKAGED` 进入 `SENT` 后，在同一事务中将中央银行接收状态设为 `RECEIVED` 并记录接收时间，模拟中央银行已接收；重复发送返回同一请求，不生成第二笔记录。
+- 已到达目标状态的重复按钮请求返回当前数据，不重新计算摘要或签名。
+
+待签名原文采用固定字段顺序：
+
+```text
+ISSUE|{bankCode}|{organizationId}|{totalAmount}|{denominations}|{currency}|{timestamp}
+```
+
+`denominations` 按面额从大到小序列化为 `面额:数量`，例如 `100:400,50:100,20:200,10:50,5:80,1:100`。
+
+## 密码学教学实现
+
+服务端使用 Bouncy Castle 提供的 SM3 和 SM2 算法：摘要为 SM3 十六进制文本，签名算法为 `SM3withSM2`。私钥不通过接口输入或返回。
+
+本期通过 `SigningKeyProvider` 端口提供 `sm2-key-02` 实验密钥；基础设施实现仅在服务端生成并缓存密钥对。响应只暴露 `signingKeyRef`、摘要和签名。后续第 2 步验签可替换为配置化或密钥库实现，不改变聚合和接口契约。
+
+## 数据模型
+
+基础初始化脚本 `src/main/resources/schema.sql` 增加以下幂等表和演示数据：
+
+| 表 | 关键字段 | 用途 |
+| --- | --- | --- |

+## REST 接口
+
+所有接口要求有效 JWT，不添加角色限定。商业银行端与中央银行端使用不同的 URL 前缀和 Controller；中央银行端不提供创建、修改、签名或发送操作。
+
+| 方法与路径 | 作用 |
+| --- | --- |
+| `GET /api/v1/commercial-banks/issuance/inventory?bankCode=BKCHCNBJ00001` | 商业银行端返回库存余额、预警阈值、建议补充金额。 |
+| `POST /api/v1/commercial-banks/issuance/requests` | 商业银行端创建 `DRAFT` 发行申请。 |
+| `PUT /api/v1/commercial-banks/issuance/requests/{id}` | 商业银行端仅在 `DRAFT` 更新金额、面额明细和币种。 |
+| `GET /api/v1/commercial-banks/issuance/requests/{id}` | 商业银行端返回完整申请与处理产物。 |
+| `POST /api/v1/commercial-banks/issuance/requests/{id}/prepare-message` | 商业银行端冻结时间戳并生成待签名原文。 |

+| `POST /api/v1/commercial-banks/issuance/requests/{id}/send` | 商业银行端模拟发送；申请变为 `SENT`，中央银行接收状态变为 `RECEIVED`。 |
+| `GET /api/v1/central-banks/issuance/requests/{id}` | 中央银行端返回接收状态、接收时间和 JSON 报文。 |
+
+不存在的申请返回 `RESOURCE_NOT_FOUND`；状态不合法或金额校验不通过返回 `VALIDATION_ERROR`；未认证请求沿用既有 Spring Security 的 `UNAUTHORIZED` 响应。
+
+## Swagger 文档
+
+Swagger 页面使用中文，所有新增 Java 源文件和 OpenAPI 元数据以 UTF-8 保存，页面不允许出现乱码。发行域接口按以下中文标签分组：
+
+- `数字货币发行模块 - 商业银行端`：库存查询、创建申请、更新申请、生成原文、摘要、签名、封装和发送。
+- `数字货币发行模块 - 中央银行端`：查询发行请求接收状态、接收时间和请求报文。
+
+每个接口通过中文 `summary` 和 `description` 明确说明所属模块、所属端、调用条件、状态变化及返回内容；请求字段和响应字段使用中文 `@Schema` 描述。OpenAPI 根标题固定为“数字人民币教学仿真后端”，接口分组和接口说明不得使用英文替代中文。
+
+## 测试标准
+
+- 领域单元测试覆盖金额守恒、非法状态流转和重复发送幂等性。
+- 应用/持久化测试覆盖库存建议金额、请求与面额明细的保存和读取。
+- `MockMvc` 测试覆盖学生有效 JWT 下的所有首期接口，以及未认证被拒绝。
+- 密码学测试校验 SM3 输出长度和 SM2 签名可由同一实验公钥验证。
+- 全量 Maven 测试在 JDK 8 下通过；以 `dev` profile 启动后，Swagger 页面可访问。
+- 访问 `/v3/api-docs` 和 Swagger UI，确认“数字货币发行模块 - 商业银行端”“数字货币发行模块 - 中央银行端”标签及中文说明可正常显示，不含乱码字符。
+
+## 明确约束
+
+- 使用 JDK 8、Spring Boot 2.7.18、MyBatis-Plus 3.5.17、Spring Security 5.7。
+- 不恢复 Flyway；所有基础表变化同步更新幂等 `schema.sql` 并在 118 测试库验证。
+- 不在日志、接口响应或数据库中保存私钥明文。
+- 不实现真实央行网络调用、准备金扣减或数字货币生成。

+# 当前用户上下文设计
+
+## 目标
+
+为后端业务代码提供统一的当前用户读取能力，并将 `GET /api/v1/auth/me` 扩展为返回主平台 Token 中经验证的完整用户资料。
+
+## 范围
+
+- SSO 成功后，从已验证的主平台 Token payload 提取并本地持久化用户资料。
+- 提供可注入的当前用户读取服务，供任意已认证业务接口使用。
+- 扩展 `/api/v1/auth/me` 返回的 DTO。
+- 不改变本系统 JWT 的主体语义、角色授权方式或本地账号密码登录流程。
+
+## 用户资料契约
+
+当前用户对象和 `/api/v1/auth/me` 的 `data` 使用下列 camelCase 字段。`roleid` 与 `studentid` 保持主平台字段拼写，以避免调用方转换。
+
+| 字段 | 来源 | 说明 |
+| --- | --- | --- |
+| `schoolId` / `schoolName` | Token `schoolId` / `schoolName` | 学校标识与名称 |
+| `collegeId` / `collegeName` | Token `collegeId` / `collegeName` | 院系标识与名称 |
+| `majorId` / `majorName` | Token `majorId` / `majorName` | 专业标识与名称 |
+| `roleid` | Token `roleid` | 主平台原始角色 ID；不替换为本系统角色 ID |
+| `userId` | Token `userId` | 主平台用户 ID，也是本地用户 ID 与 JWT subject |
+| `username` | Token `username` | 用户登录账号 |
+| `name` | Token `name` | 用户姓名 |
+| `classId` / `className` | Token `classId` / `className` | 班级标识与名称 |
+| `studentid` | Token `studentid` | 学号/学生标识 |
+
+标识类字段以字符串持久化和返回，以兼容主平台可能出现的非纯数字编码；`userId` 是唯一的数值主键，解析为 `long`。
+
+## 架构与数据流
+
+```text
+主平台 Token
+  -> PlatformTokenVerifier（验签、校验必填资料）
+  -> PlatformActor（完整的已验证身份）
+  -> PlatformIdentityProjectionService（事务内更新 sys_user、快照、授权角色）
+  -> platform_user_snapshot
+
+本系统 JWT subject(userId)
+  -> CurrentUserService
+  -> platform_user_snapshot
+  -> 业务代码 / GET /api/v1/auth/me
+```
+
+`PlatformTokenVerifier` 只能在签名、登录时间和现有身份声明均通过后，才构造含完整资料的 `PlatformActor`。它校验 `userId`、`username`、`name`、`roleid` 必填，并将 `roleid` 映射为既有 `TEACHER` 或 `STUDENT` 以保留 Spring Security 授权行为。学校、院系、专业、班级和 `studentid` 允许为空，以兼容教师等不具备学生组织信息的身份。
+
+`PlatformIdentityProjectionService` 在现有事务中更新扩展后的 `platform_user_snapshot`。快照是当前用户资料的唯一读取源；业务请求不会重新解析主平台 Token，也不会查询主平台数据库。
+
+`CurrentUserService` 位于 `security.application`，从 Spring Security 的 `Jwt` 读取 subject，查询快照并返回不可变当前用户对象。未认证、subject 不是正整数或快照不存在时抛出既有 `UNAUTHORIZED` 业务异常。Controller 只调用该服务并将结果转换/直接作为响应 DTO 返回，不直接访问 Mapper。
+
+## 持久化
+
+扩展 `platform_user_snapshot`，增加学校、院系、专业、班级、主平台原始角色 ID 和学生标识字段。`schema.sql` 需同时覆盖新环境建表和已有数据库的幂等升级；不引入 Flyway。快照中保留 `role_key` 作为本系统授权映射，新增的 `roleid` 独立保存主平台原始值。
+
+## API 与错误处理
+
+`GET /api/v1/auth/me` 仍要求本系统 Bearer JWT，并返回既有 `ApiResponse` 包装。成功响应只包含上述用户资料字段，不包含密码、主平台 Token、刷新令牌或快照同步时间。未认证或快照缺失时维持现有未授权错误语义。
+
+## 测试
+
+- Token 验证测试：完整资料被解析进已验证身份；缺少必填字段的 Token 被拒绝。
+- 身份投影测试：扩展资料写入并在重复 SSO 时更新，不产生重复角色关联。
+- 当前用户服务/接口测试：持有本系统 JWT 时能读取全部字段；无效 subject 与不存在快照返回未授权。
+- 运行项目规定的 Maven 测试与打包命令。
+
+## 非目标
+
+- 不向业务 Controller 暴露用户、角色或快照 CRUD。
+- 不在每次业务请求时调用主平台或解析主平台 Token。
+- 不在本系统 JWT 中复制完整用户资料。

+# 本地 Token SSO 设计
+
+## 目标
+
+数字人民币后端不连接、不读取主平台数据库。主平台通过跳转链接携带 JWT；后端使用双方约定的共享密钥验证该 JWT，并仅使用 Token 中的用户数据创建或更新本地用户，然后直接签发本系统 JWT 并重定向给前端。
+
+本地账号密码登录必须保留。主平台 Token 中携带的密码是本地密码的同步来源：每次 SSO 登录成功后，后端都将该密码 BCrypt 编码后写入本地用户表。因此，用户在主平台修改密码并再次通过 SSO 跳转后，可立即使用新密码独立登录本系统。
+
+## 边界与依赖
+
+保留的外部依赖只有主平台 Token 的共享密钥；不保留任何主平台数据源、数据库表查询、同步任务或远程身份仓储。
+
+主平台 Token 采用 PEVC 示例相同的标准三段 JWT 与 HMAC 共享密钥验签。运行时通过环境变量配置共享密钥，禁止将其提交到代码库。
+
+必需 claim：
+
+- `userId`：主平台用户 ID，也是本地 `sys_user.id`。
+- `username`：本地登录账号。
+- `password`：主平台当前明文密码，仅用于立即 BCrypt 编码后保存，不记录到日志、快照或响应。
+- `roleid`：`3` 映射为 `TEACHER`，其他值映射为 `STUDENT`。
+
+可选 claim：`name`、`schoolId`、`schoolName`、`classId`、`className`、`collegeId`、`collegeName`、`studentNo`、`realName`。这些字段仅在本地快照或本系统 JWT 扩展字段中使用。
+
+## SSO 流程
+
+1. 前端或主平台访问 `GET /api/v1/auth/sso?token={parentToken}`。
+2. 后端使用共享密钥验证 JWT 的签名与有效期，并提取必需 claim。
+3. 后端以 `userId` 查询本地 `sys_user`。
+4. 若不存在，使用 Token 数据创建本地用户、用户快照和 `sys_user_role`；若存在，更新账号、启用状态、快照、角色关联及 BCrypt 密码散列。
+5. 后端以本地用户信息签发数字人民币系统 JWT，并以 302 重定向至 `{frontend-callback-url}/sso-callback?token={digitalRmbToken}`。
+
+本系统 JWT 的 subject 为本地 `userId`，并包含 `preferred_username` 与本地角色列表。SSO 入口不再生成或消费一次性交换码。
+
+## 数据一致性与错误处理
+
+用户、快照、角色关联和密码散列更新在同一个本地数据库事务内完成。已验证 Token 的用户同步必须幂等：同一用户多次跳转不会产生重复用户或角色行。
+
+签名无效、过期、缺失必需 claim、非法 `userId` 或空账号/密码时，拒绝登录并重定向至前端登录页的 SSO 失败状态。不得在响应、日志或异常中输出原始 Token 或密码。
+
+## 删除项
+
+删除以下主平台数据库依赖：
+
+- `platformReadOnlyDataSource` 与 `platformNamedParameterJdbcTemplate`。
+- `PlatformIdentityRepository` 的远程实现及相关主平台查询 SQL。
+- `PlatformIdentitySyncJob` 及 `platform-integration.sync` 配置。
+- 依赖远程身份数据验签的旧四段 Token 校验逻辑。
+
+删除一次性交换码的 SSO 路径及其服务调用。为避免破坏现有数据库数据，既有 `auth_login_exchange_code` 表可暂时保留但不再被应用访问。
+
+## 验证标准
+
+- 应用启动时只创建一个本地业务数据源。
+- 有效主平台 JWT 可创建本地用户并直接重定向携带本系统 JWT。
+- 已存在用户每次 SSO 后密码散列都会更新；使用 Token 中的新密码可通过本地 `/api/v1/auth/login` 登录。
+- 无效签名、过期 Token 或缺失必需字段不能创建/更新本地用户。
+- 本地账号密码登录、当前用户查询和注销的既有行为保持可用。
