# US02-01 — Extract Safety and Existing Web UI Donors

Epic: [E02](../E02-unified-workflow-shell.md)

As a maintainer, I want safety logic and proven web interactions extracted from the
existing tools so the unified workflow retains working behavior and visual language.

## Acceptance criteria

- The donor ledger maps scoring, thresholds, decisions, EXIF keywords, filters,
  layouts, tokens, keyboard controls, and error states to new modules.
- Behavior changes required by stable identity or shared jobs are documented.
- Shared modules have no dependency on archived entry points.

## Automated tests

- Characterization tests compare donor and extracted behavior on the same fixture IDs.
- Snapshot/interaction tests cover reused design tokens and critical controls.

## Dependencies

- E01 complete
