Explorer Decision observatory

Combines signals, assumptions, counter-evidence, and ownership into one decision surface for filters, saved views, dimensions, and analytical routes; it is designed to move through analytical perspectives without losing query context. Users can test scenarios, inspect provenance, and record a reversible decision. The data exploration controls variant is specialized for controls must avoid creating crawlable faceted URL explosions. Users can move through analytical perspectives without losing query context while understanding the current state, available choices, and resulting consequence.

Implementation field notes

Use explorer decision observatory confidently.

The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.

Good fit for

  • Data controls
  • Data scope
  • Combines signals, assumptions, counter-evidence, and ownership into one decision surface for filters, saved views, dimensions, and analytical routes

This data controls pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • The primary purpose and current state remain available as text and do not depend on color, motion, pointer position, or visual geometry.
  • Every interaction has keyboard equivalence, visible focus, predictable Escape behavior where applicable, and appropriately scoped status announcements.
  • Reduced-motion, 200% zoom, long-content, narrow-container, and forced-color behavior are part of the implementation acceptance criteria.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt primary signal, secondary signal, layered surface, primary text through the Inspector.
  3. Connect the defensive JavaScript, then test every control with a keyboard.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
