+rationale: Continue the larger bounded breadcrumbs refactor cadence by extracting repeated anchor/back-link crumb markup into one local helper while preserving non-Link semantics.
+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 `renderAnchorCrumb(href, label, onClick, listItemClass)` in `components/breadcrumbs.js` for repeated `<a ...>` breadcrumb actions.
+- Replaced repeated anchor/back-link crumb blocks in:
+    - `/myportal/searchresults` my-portal anchor crumb
+    - `/newappeal/[appealtypes]` and `/myportal/[appealtypes]` step-back crumbs
+    - `/myportal/representation` back-chevron action crumbs (all three state branches)
+- Preserved original click handlers, href values, and class semantics (`govuk-breadcrumbs__link-item`, `backChevron`) to keep behavior parity.
+
+Validation:
+
+- `npx eslint components/breadcrumbs.js` -> pass.
+- `node tests/phase22/index.test.cjs` -> pass (combined suite).
+
+Follow-ups:
+
+- Next slice recommendation: consolidate remaining one-off inline breadcrumb `<li><Link ...>` blocks still present in edge branches (e.g., `/newappeal/[appealtypes]`, `/myportal/[appealtypes]`, `/case`) and consider introducing an optional `renderBackCrumb(...)` semantic wrapper for readability.
