Capture writtenoff formal-table dev-db evidence for REV004

This evidence snapshot records the application-dev target database, DDL apply
and replay status, targeted verification commands, fresh-jar smoke outcomes,
and cleanup proof for the writtenoff formal-table batch.

Constraint: Evidence must remain aligned with the backend writtenoff formal-table batch and the actual application-dev database
Rejected: Fold evidence into unrelated doc updates already present in this branch | would mix scopes and obscure traceability
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Update this evidence if later writtenoff smoke is rerun on a different port or with different seeded IDs
Tested: Reviewed against backend compile/test results and direct psql cleanup verification on 2026-04-17
Not-tested: No additional doc rendering/export pipeline run for this evidence-only change

+# REV004 writtenoff formal-table 已应用到 application-dev 测试库（2026-04-17）
+
+## 目标库
+依据：
+- `sw-business/sw-business-server/src/main/resources/application-dev.yaml`
+
+解析结果：
+- Host：`192.168.10.130`
+- Port：`5436`
+- DB：`sw_system`
+- User：`sw_system`
+
+## 已执行脚本
+- `sql/rev004/REV004_writtenoff_formal_tables_deploy.sql`
+
+## DDL 执行结果
+结果：**PASS**
+
+已确认存在：
+- `biz_writtenoff_adjust`
+- `biz_writtenoff_adjust_detail`
+- `biz_writtenoff_adjust_seq`
+- `biz_writtenoff_adjust_detail_seq`
+
+已确认幂等重放通过：
+- second apply 输出 `already exists, skipping`
+- 无重复约束/重复索引异常
+
+## 代码验证
+### compile
+```bash
+mvn -pl sw-business/sw-business-server -DskipTests compile
+```
+结果：**PASS**
+
+### targeted tests
+```bash
+mvn -pl sw-business/sw-business-server \
+  -Dtest=AccountingAdjustSoldProcessServiceImplTest,AccountingAdjustActionServiceImplTest,AccountingAdjustProcessServiceImplTest,AccountingAdjustQueryServiceImplTest,WrittenoffFormalizationServiceTest test
+```
+结果：**PASS**
+- Tests run: 41
+- Failures: 0
+- Errors: 0
+
+## HTTP smoke（fresh jar, port 48093）
+### submit
+- `sold-submit` on charge `992005` → `REV004-SLD-992005-20260417143622`
+- `sold-submit` on charge `992006` → `REV004-SLD-992006-20260417143623`
+- 返回统一为：
+  - `objectType = WRITTENOFF_ADJUST`
+  - `approvalStatus = PENDING_APPROVAL`
+  - `resultStatus = PENDING_APPROVAL`
+  - `writeBackStatus = PENDING`
+
+### DB 回读
+`biz_writtenoff_adjust_detail`：
+- submit 后 detail 进入 `PENDING_APPROVAL / SUBMIT`
+
+### query
+- `GET /admin-api/business/accounting-adjust/get?adjustmentNo=...` 对 writtenoff 已返回 formal detail
+- `GET /admin-api/business/accounting-adjust/page?...objectType=WRITTENOFF_ADJUST` 已返回 formal-first 列表
+
+### approve / reject
+- approve：`/admin-api/business/accounting-adjust/approve`
+  - 返回 `APPROVED/SUCCESS/UPDATED`
+  - 账单 `extended_amount` 归零、`discount_money` 累加、`pay_state=SETTLED(2)`
+- reject：`/admin-api/business/accounting-adjust/reject`
+  - 返回 `REJECTED/FAIL/SKIPPED`
+  - 账单保持原值，不执行核销回写
+
+## 测试数据清理
+smoke 完成后已删除：
+- `biz_operat_log / detail`（identify_value = `992005`, `992006`）
+- `biz_writtenoff_adjust / detail`
+- `biz_charge`（`992005`, `992006`）
+- `biz_cust`（`REV004_WO_SMOKE_A`, `REV004_WO_SMOKE_B`）
+
+回读结果：
+- `writtenoff_main_left=0`
+- `operat_log_left=0`
+- `charge_left=0`
+- `cust_left=0`
+
+## 运行态清理
+用于 fresh-jar HTTP smoke 的临时实例：
+- port `48093`
+
+已停止，当前无残留 LISTEN 进程。
+
+## 当前结论
+本轮 writtenoff formal-table 已达到：
+1. DDL 可落库且可幂等重放；
+2. sold submit 能落 pending formal main/detail；
+3. approve/reject 会同步 formal 状态；
+4. detail/page 对 `WRITTENOFF_ADJUST` 已能返回 formal-first 结果；
+5. sold submit 已补事务边界，避免 operat_log 与 formal-table 半成功；
+6. 审批/驳回缺失 formal 主记录时将显式报错，避免静默漏更新。
+
+## 当前未完成
+- writtenoff formal-first 目前仍是最小实现，后续仍可优化 page 查询性能（避免 listAll + getView N+1）；
+- 若需要更细的 charge_detail 差异映射到 formal 明细，可在后续补强。
