Drift Detection
See what changed between comparable validation runs and trace the delta to the affected resource and field.
Separate a data change from a change in the checks
A delta is meaningful when the earlier and current runs use a comparable scope and validation basis.
Earlier run
The accepted reference point.
Current run
The same source checked again.
Run comparison
Check comparability before interpreting the delta.
What changed
Added, resolved and unchanged findings.
Follow a new finding from the comparison to its field.
See the new error against the baseline
A new structural error appears after a source change. The comparison separates it from findings already present in the baseline.

Find the affected Patient
Inspect the new finding to see its field path and the one Patient affected in this run.

Inspect the changed value
Patient.active contains the string true. FHIR requires a boolean. The resource view shows the value that explains this same regression.

The compared runs use the same recorded validation basis. This new finding identifies a data change; deciding whether it was intended still requires the source context.
