' Schema source: Flyway V1–V69 (excl. V37, V43 — intentionally removed)
' Schema as of:  V69 (2026-05-27)
' ⚠ This is a versioned snapshot. Update when the schema changes significantly.
' Note: V69 adds columns only (persons.source_ref, tag.source_ref, document
' precision/attribution fields); no new FK relationships, so this diagram is unchanged.
