Say what is known.如实说明已知。
Assumptions and unknowns are written down early. We do not sell certainty where discovery is still needed.尽早记录假设与未知项，不把尚待验证的问题包装成确定结论。
THE METHOD ✳ ENGINEERING, MADE LEGIBLE
From brief
to working.从需求，
到可运行。
Zhijiang Sourunjiao Technology Co., Ltd. is built around a straightforward promise: make the hard part understandable, make the solution dependable, and leave the next team with a clean handoff.枝江市艘闰娇科技有限公司坚持一个简单承诺：把难点讲明白，把方案做可靠，并为接手团队留下清晰交接。
PROJECT SPECIMEN / 06:12
A good handoff is part of the build.交接做好，才算构建完成。
Readable source. Tested interfaces. A short operations guide. Nothing hidden behind a single person's memory.代码易读、接口经过测试、运维说明简洁明了。不把关键知识藏在某个人的记忆里。
SJ / QUALITY NOTE 04
- 01Listen before scoping先听清，再定范围
We document the users, constraints, dependencies and measures of success before estimating.评估前先记录使用者、约束、依赖关系与成功标准。
- 02Draw the system boundary画清系统边界
Interfaces, failure modes and ownership are explicit; integration is not left to assumption.接口、失效模式与责任归属清晰说明，集成不靠猜测。
- 03Build in testable slices按可测试单元构建
Milestones produce reviewable artifacts rather than vague activity reports.里程碑交付可检查成果，而非含糊的工作进度描述。
- 04Hand over with care认真完成交接
Documentation, installation and support boundaries are included in the plan.文档、安装与支持边界均纳入交付计划。
THREE HOUSE RULES
Quality is a practice,
not a footer badge.质量是做法，
不是页脚徽章。
These rules apply equally to software, robotics, integration and ongoing operations.这些原则同样适用于软件、机器人、集成与持续运营。
Respect the environment.尊重运行环境。
Solutions fit the client's infrastructure, safety procedures and actual operating conditions.方案适配客户的基础设施、安全流程与真实运行条件。
Leave it operable.交付后能运行。
A system is not finished until the designated team can understand, monitor and support it.指定团队能够理解、监控并支持系统，才算真正完成交付。
QUESTIONS, ANSWERED
A few useful clarifications.几个常见问题。
Is the 42-line index a list of guaranteed deliverables?42 项业务索引是否代表保证交付清单？
No. It describes registered business scope. Each real engagement is subject to feasibility, a written scope, applicable approvals and a separate agreement.不是。索引展示的是注册经营范围。每项实际合作需经过可行性确认、书面范围约定、适用审批及另行签署协议。
Can you work with existing systems and equipment?能否对接现有系统和设备？
Integration is part of our registered scope. We first review interface documentation, access and safety constraints, then confirm the integration boundary in writing.系统集成属于我们的注册业务范围。我们先审阅接口文档、访问条件与安全约束，再以书面方式确认集成边界。
Where is the company located?公司位于哪里？
