# 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.
