Recovery Import Column Mapper
Maps external columns to internal fields while exposing type and validation conflicts for multi-error and interrupted forms; it is designed to lead users from problem to resolution while preserving entered work. Keyboard mapping updates sample values, ignored columns, and readiness status. The validation recovery inputs variant is specialized for errors may originate locally, remotely, or after submission. Users can lead users from problem to resolution while preserving entered work while understanding the current state, available choices, and resulting consequence.

Implementation field notes
Use recovery import column mapper 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.
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
- Copy the standalone HTML and scoped CSS into an isolated page.
- Adapt input signal, interpretation highlight, input surface, primary text through the Inspector.
- Connect the defensive JavaScript, then test every control with a keyboard.
- Review the result at 375, 768, 1024, and 1440 pixels before shipping.
