+### CL-22541-K: breadcrumbs grouped two-crumb helper extraction
+
+date: 2026-04-09  
+author: Cline  
+scope: `components/breadcrumbs.js`  
+type: change  
+rationale: Continue the same bounded refactor cadence by extracting recurring two-crumb patterns into small grouped helpers while preserving explicit route branches.
+impact: Refactor-only readability/deduplication improvement; no intended route/auth/session/API/EN-CY/a11y behavior change.
+status: completed
+
+Summary:
+
+- Added grouped helper `renderMyPortalSectionCrumbs(sectionLabel)` for recurring my-portal + section text pairs.
+- Added grouped helper `renderDnsCaseReferenceCrumbs(referenceValue)` for recurring DNS applications link + case-reference pairs.
+- Replaced duplicated route branches with grouped helper usage for:
+    - `/myportal/addresssearch`, `/myportal/advancedsearch`, `/myportal/contactus`
+    - `/dnsdetails`, `/dns/[developmentName]`
+- Preserved existing href behavior (including EN/CY DNS applications link), labels, and case-reference rendering.
+
+Validation:
+
+- `npx eslint components/breadcrumbs.js` -> pass.
+- `node tests/phase22/index.test.cjs` -> pass (combined suite).
+
+Follow-ups:
+
+- Next slice recommendation: extract a small route-to-renderer map for static single-branch crumbs (where branch has no bespoke side-effects) so the main JSX conditional chain shrinks further without altering explicit behavior in dynamic/sensitive branches.
