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

3. 2026-05-17T15:30:00-07:00 · DEPRECATION_CONFIRMED_AS_OUT_OF_SCOPE · claude

   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.
