# Clinical Reasoning Database — Sprint 4 Completion Report

## Delivered

Sprint 4 creates the first functioning Clinical Content Workbench. It is intentionally separate from the future full Windows application and preserves the current PhUCKIT release as the initial consumer rather than replacing it.

## Workbench capabilities

- Create, search, edit, and delete medication records.
- Maintain generic names, brands, OCR aliases, common misspellings, pharmacologic classes, therapeutic classes, and indications.
- Create claim-level records for every clinical domain in the complete reasoning-database specification.
- Attach multiple evidence records to an individual claim.
- Require an exact source section plus at least one precise locator.
- Store subsection, page, table, figure, recommendation number, paragraph/bullet, appendix, and electronic anchor independently.
- Record the exact claim supported and a concise support summary.
- Classify evidence as supporting, qualifying, or conflicting.
- Apply primary and independent secondary review.
- Block author self-review and same-person primary/secondary review.
- Require conflict resolution before publication.
- Track claim stages from draft through published.
- Validate the complete repository and display all blocking issues.
- Import and export the repository as human-readable JSON.
- Autosave locally in the browser.

## Safety and content status

The package contains structural examples only. It does not contain clinical medication recommendations and does not falsely mark any medication content as clinically validated.

## Use

On Windows, double-click `START_WORKBENCH.cmd`.

The workbench opens in the default browser. Data autosaves to browser local storage. Use Export regularly to create a portable repository JSON file.

## Validation

Node-based static tests verify:

- Presence of every requested medication domain.
- Exact section and precise locator enforcement.
- Independent review controls.
- Conflict-resolution gate.
- Required workbench tabs and editors.
- Parseability of structural JSON examples.

## Next sprint

Sprint 5 should establish the first gold-standard content set, source intake workflow, research queues, claim templates, and coverage reporting. Clinical population should begin with a deliberately small set of complete records rather than shallow bulk ingestion.
