  action: DEPRECATED_PROPERTY_RECORD
  changes: Deprecated generic observation relation carrier; later replacement should
    use more specific trait records that combine the relation with measured
    quantity, growth context, chemical, value bounds, or other entity.

  changes: |
    DEPRECATED status confirmed as final after the predicate+class composition
    pivot (#54/#55/#56). This record's observation-shape modelling is out of
    scope for TraitMech; the trait vocabulary + mechanism need is met by the un-
    deprecated METPO predicates, and per-organism numeric observations belong
    downstream (KG-Microbe / BacDive). See
    docs/DEPRECATED_REPLACEMENT_PROPOSAL.md, section 'Observation-value records
    stay deprecated', for the rationale.
