Schema error 'must match exactly one schema in oneOf' on reserveType.
Cause
The reserve type does not appear in the AFDRES list of the release; the list was extended in July 2026 (issue #134, pending release).
Fix
Choose the code from the AFDRES list that belongs to the release; if a reserve type is missing, request it via GitHub.
