+### CL-22541-F: breadcrumbs multi-pattern helper bundle (text + link crumbs)
+
+date: 2026-04-09  
+author: Cline  
+scope: `components/breadcrumbs.js`  
+type: change  
+rationale: Deliver a slightly larger bounded slice by extracting and reusing multiple breadcrumb rendering patterns (plain text crumb and linked crumb) across several route branches.
+impact: Refactor-only JSX deduplication and consistency improvement in breadcrumb rendering; no intended route/auth/session/API/EN-CY/a11y behavior change.
+status: completed
+
+Summary:
+
+- Added reusable helpers in `components/breadcrumbs.js`:
+    - `renderTextCrumb(label)`
+    - `renderLinkCrumb(href, label, onClick)`
+- Replaced multiple repeated inline breadcrumb blocks across search/address/myportal/dns branches with helper calls.
+- Included onClick-capable link helper usage in the `/myportal/case/id/[incident]` address-results breadcrumb branch to preserve `router.back()` behavior.
+- Combined with existing `renderMyPortalCrumb` and `renderCaseReferenceCrumb` helpers for more consistent branch composition.
+
+Validation:
+
+- `npx eslint components/breadcrumbs.js` -> pass.
+- `node tests/phase22/index.test.cjs` -> pass (combined suite).
+
+Follow-ups:
+
+- Next slice recommendation: extract remaining repeated inline link crumbs for case/DNS branches that still hardcode `<li><Link ...>` (e.g., `/myportal/case`, `/myportal/case/[ticketnumber]`, `/dnsdetails`, `/dns/[developmentName]`) to complete link-pattern consolidation.
