-- repeated dominant pattern identified
-- several partial abstractions already present

 - adopt first in bounded, read-only display families
 - preserve current fallback behaviour per consumer unless an explicit standardization decision is approved
 
+#### Status
+
+Completed.
+
+Delivered in this workstream:
+
+- shared resolver introduced
+- helper test coverage
+- helper contract verified and corrected
+- adoption across:
+    - admin
+    - search
+    - My Portal
+    - summary types
+- stale JSONPath import cleanup
+- behaviour-preserving migration
+
+Remaining JSONPath usage in adopted areas is intentional where it falls outside the helper boundary.
+
+That includes concerns such as:
+
+- keyed lookup translation
+- project-type list translation
+- hyperlink / website rendering
+- mixed presentation rows
+- lifecycle / status / post-decision interpretation
+- other presentation-specific derived values
+
 #### Expected Maintenance Benefit
 
 - reduced duplication of display-resolution logic
