1. standards-status still says deprecated. On the restored element in source/measure/structuredefinition-Measure.xml (line ~759):

   <element id="Measure.topic">
     <extension url="http://hl7.org/fhir/StructureDefinition/structuredefinition-standards-status">
       <valueCode value="deprecated"/>
     </extension>

   To un-deprecate, this extension should be removed (or its valueCode changed to a non-deprecated status). Leaving it as deprecated contradicts the agreed resolution.

2. The Measure-topic SearchParameter wasn't restored. Commit 06ab81280a (the original FHIR-55436 removal) also deleted the Measure-topic SearchParameter entry from source/measure/bundle-Measure-search-params.xml. That deletion has not been reverted. Searching the file for Measure-topic or topic returns no matches.

3. measure.svg wasn't restored. The same removal commit deleted the topic : CodeableConcept [0..*] text block from source/measure/measure.svg (lines around the n1587/n1588 ids). That has also not been reverted — grepping measure.svg for topic returns no matches.

4. The intro entry for FHIR-55436 is now stale. source/measure/measure-introduction.xml line 31 still reads:

   <li><a href="https://jira.hl7.org/browse/FHIR-55436">FHIR-55436</a>: Remove deprecated Measure.topic</li>

   Since the change is reversing that removal, this entry should either be removed (if the original removal landed pre-ballot4 and there is nothing to note) or rewritten to describe the un-deprecation. As written it is misleading to balloters.
