Prin-Dev — Development Directives Metaphor

Purpose: Development principles as "laws of physics for the construction zone." Use when you need to ground in Paper Napkin, Platinum Rule, Stats Access Rule, or estimation principle.

When to use:

• When tempted to patch instead of regenerate (Paper Napkin)
• When designing for users without aligning to their reality (Platinum Rule)
• When placing stats or analytics (Stats Access Rule)
• When estimating work in time instead of scope
