RFR-70F640EB — Calibrate construct and measurement validity: Purpose

Research opportunity

Calibrate construct and measurement validity for the claims or recommendations in “Purpose.”

Background

The originating artifact is accepted by the repository publishing inventory with status “research-baseline.” Its F-008: Visual redesignability depends more on semantic and CSS boundaries than on custom elements section provides the immediate evidence boundary.

Evidence trace

• Origin document: content/projects/design-library/research-report/component-library-foundations-research-report.md
• Section: F-008: Visual redesignability depends more on semantic and CSS boundaries than on custom elements
• Specific assumption challenged: The source's treatment in “F-008: Visual redesignability depends more on semantic and CSS boundaries than on custom elements” is sufficiently supported for its intended scope.
• Supporting evidence excerpt: “Custom elements do not inherently make an interface redesignable. A poorly modeled custom element can be more rigid than ordinary HTML. Redesignability comes from durable content models, presentation-neutral DOM order, parent-owned composition, contextual tokens, low-specificity CSS, and controlled escape hatches.”
• Reason this opportunity exists: Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.

Unknowns

• Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.

Dependencies

• None; this is foundational work.

Suggested REP and methodology

• Suggested REP: REP-PURPOSE-MEASUREMENT
• Methodology: Define the construct, compare convergent and discriminant measures, estimate reliability, test measurement invariance, and publish calibration data.
• Expected outputs: Construct definition, measurement protocol, reliability study, calibration dataset, and validity report.
• Success criteria: Measures meet declared reliability and validity thresholds across the principal populations and contexts.
• Recommended agent: measurement-research-agent
• Estimated effort: Medium
• Expected knowledge gained: Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.

Evaluation

Confidence in this opportunity: moderate. Status: Open.
