PRINCIPLE 01
System / Mutation
Design systems establish continuity while controlled mutation keeps identity responsive to changing contexts.
RATIONALE / OPERATING INTERPRETATION
System establishes continuity, production control, and legible structure. Mutation introduces bounded expression without displacing those controls.
FAILURE MODE
Unbounded expression fragments identity, interaction, content order, and production control.
DECISION CONSEQUENCE
Approve structural, truth, accessibility, responsive, and production constraints before expressive variation.
OPERATING BEHAVIOR
Hold common hierarchy and controls; introduce mutation only inside a declared and reviewable boundary.
REFUSAL / BOUNDARY
Controlled mutation does not override usability, accessibility, content truth, responsive behaviour, or production constraints.
