 - Bruce asked whether iOS Fid4 has a release-build optimization or code-minification concept comparable to Android; treat this as a validation/build-configuration question until clarified, not as evidence of a known iOS minification issue.
 - Jeff clarified the validation ask: inspect whether Fid4 has simulator-versus-physical-device or generated-build differences in build settings/schemes/configurations, including any optimized-build-size or release-style settings that could explain behavior seen in generated builds but not when running locally.
 - Current likely Fid4 build differences to report: Trunk/generated builds use the `Release` configuration while local runs are usually `Debug`; optimization settings such as `SWIFT_OPTIMIZATION_LEVEL` and `GCC_OPTIMIZATION_LEVEL` can differ; Jenkins uses a generated `build-overrides` xcconfig that local builds do not use and may affect values such as secrets; and CocoaPods dependency resolution can vary depending on the local specs repo state.
+- External review reached Bruce and produced minor feedback. David addressed the feedback and pushed the suggested change.
+- One accepted review change was to set `responseKey: String? = nil` as the default in `FlowRESTOperationContract`, allowing operations such as `updateSlots`, `storeString`, and `publishEvent` to omit `responseKey` when not needed.
+- The native Swift domain enum file should remain as the canonical location for XFlow domain enums after removal of GraphQL-generated code.
+- Jeff directed David to move the ticket to Done, while keeping the PR unmerged for at least 30 days.
+- Branch maintenance is now part of the work: keep the GraphQL/Apollo-removal branch up to date with `main` until the REST backend/toggle validation window allows merge. If future `main` merges create conflicts that look non-trivial, raise it so a 1-2 point maintenance story can be created.

 ## Sequencing
 
 - This story remains sequenced before `PDIAP-15836`.
+- This branch should merge to `main` before the future `PDIAP-15836` / `PDIAP-12284` branch is updated and merged.
