# Specification Quality Checklist: 设备信任免绑手机号

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-09-20
**Feature**: [spec.md](../spec.md)

## Content Quality

- [x] No implementation details (languages, frameworks, APIs) — 注：tempKey/state/info_user_oauth 等为现有产品契约标识与项目既有概念，沿用 017-oauth-login 规格的行文惯例，非新引入的实现细节
- [x] Focused on user value and business needs
- [x] Written for non-technical stakeholders
- [x] All mandatory sections completed

## Requirement Completeness

- [x] No [NEEDS CLARIFICATION] markers remain — 设计决策已在头脑风暴阶段与用户逐一确认（痛点场景、设备标识来源、一键确认交互、LINE state 方案）
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable
- [x] Success criteria are technology-agnostic (no implementation details) — SC-003 以"与现有接口同一量级"表述，避免绝对数值
- [x] All acceptance scenarios are defined
- [x] Edge cases are identified（老版本兼容/无信任/tempKey 过期/不匹配/账号停用/已绑定优先/共用设备/异常值）
- [x] Scope is clearly bounded（不含商户/骑手端、不含前端实施）
- [x] Dependencies and assumptions identified

## Feature Readiness

- [x] All functional requirements have clear acceptance criteria
- [x] User scenarios cover primary flows（三条用户故事覆盖：免绑主流程、信任建立、LINE 回调链路）
- [x] Feature meets measurable outcomes defined in Success Criteria
- [x] No implementation details leak into specification

## Notes

- 所有条目通过，无需迭代。规格可直接进入 `/speckit-plan`。
- FR-009/FR-010 为项目流程性要求（数据库变更管理、前端契约交付），对应 CLAUDE.md 规范。
