+# WBV2-P1420-001: complete Web product workflow implementation

+- task: WBV2-P1420-001
+- parent: WBV2-P1420-000
+- status: in_progress
+- gap: product-workflow:user-reachable-main-commands
+- ownerFamily: WEB_PRODUCT
+- targetImplementationClass: PRODUCT_WORKFLOW
+- commandBudget: one implementation subtask per Codex turn
+- Implementation entrypoint: `python3 my-tools/run_web_product_migration.py`
+
+## 目标
+
+Complete the implementation tasks in `tests/golden/WBV2/web-product-backlog.json`.
+The `3745` source-unit inventory is traceability-only and is not the completion denominator.
+
+## 输入与范围
+
+- `web/app/src/app/App.tsx`
+- direct typed protocol helpers named by the active backlog task
+- `docs/WEB_PRODUCT_MIGRATION_STRATEGY.md`
+
+## 验收
+
+- implement exactly one backlog task per Codex turn
+- preserve existing dirty changes
+- do not run tests, builds, typecheck, browsers, validators, or coverage binding
+- do not claim similarly named desktop operators
+- outer scheduler owns subtask rotation
+- `node tools/web/print-task-context.mjs`
+
+## 失败边界
+
+- a failed Codex turn remains pending and is retried without advancing the backlog
+- unrelated dirty files are never reverted or included in an automatic commit
+- no implementation task changes the source traceability ledger
+
+## 交付与回滚
+
+All 16 workflow modules are implementation-complete. Runtime defects are opened from user operation.
+- Backlog: `tests/golden/WBV2/web-product-backlog.json`
+- Report: `tests/golden/WBV2-P1420-001/product-implementation-report.json`
+- Rollback: stop `my-tools/run_web_product_migration.py` and retain the last completed subtask.
