TOPIC MAP / 01
Expand from product spec sheets into complete decision problem graphs
Engineers don't just ask what a product is; they ask how to design it, how to select it, where it might fail, and who is worth collaborating with.
Design
Rack heat load / flow rate / approach temperature / pump redundancy
Reliability
Leak detection / QD failure / contamination / corrosion
Selection
CDU sizing / specification comparison / vendor checklist
Compatibility
Cold plate / coolant / material / facility water
Vendor Discovery
CDU manufacturers / global suppliers / OEM & ODM
ENGINEERING STANDARD / 02Make every conclusion
Make every conclusion
All have engineering context.
High-value pages should explain parameter definitions, design assumptions, scope of application, risks, standard basis, author, and update date.

Technical content is not about length,\nbut about reaching engineering decision points
Taking CDU as an example: Ordinary content only provides conclusions; engineered content must explain boundaries, parameters, risks, and verifiable evidence.
