TRD Creation - Architecture Before Implementation

Foundational Principle

Architecture decisions (HOW/WHERE) must be technology-agnostic patterns before concrete implementation choices.

Specifying technologies in TRD creates:

• Vendor lock-in before evaluating alternatives
• Architecture coupled to specific products
• Technology decisions made without full dependency analysis

The TRD answers: HOW we'll architect the solution and WHERE components will live. The TRD never answers: WHAT specific products, frameworks, versions, or packages we'll use.

⛔ HARD GATE: Design Validation Prerequisite (Step -1)

This check MUST happen BEFORE any TRD work begins.
