Data Quality

Sprint 16 adds a local, permission-gated foundation for data quality review, duplicate review, record verification, staff adoption, daily checklists, and system QA issue tracking.

The foundation is intentionally human-led. It records issues, decisions, verification checks, and checklist progress, but it does not auto-merge duplicates, overwrite records, run external integrations, or perform destructive cleanup.

Web routes

• /data-quality shows the summary cards, data quality issue intake, recent issues, and QA carryovers.
• /data-quality/duplicates records duplicate review pairs and decisions.
• /data-quality/verifications tracks manual record verification checks.
• /data-quality/adoption records local staff adoption events.
• /data-quality/daily-checklists creates and updates daily rollout/checklist items.
• /data-quality/qa-issues tracks manual QA findings and sprint carryovers.

Data model

Sprint 16 adds these PostgreSQL-backed records:

• DataQualityIssue
• DuplicateReview
• RecordVerification
• StaffAdoptionEvent
• DailyChecklist
• DailyChecklistItem
• SystemQaIssue

Each record has a stable number, status enum, timestamps, user relations where relevant, and activity logging for create/status-change actions.

Guardrails

• Duplicate review is decision tracking only. No automatic merge is performed.
• Record verification is manual. It does not mutate the source record being verified.
• Staff adoption events are manually recorded in the app. No external telemetry is added.
• System QA issues are local tracking records. They do not create production deployment or monitoring hooks.
