 - 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.
 
+### CL-22541-L: breadcrumbs simple-route renderer map introduction
+
+date: 2026-04-09  
+author: Cline  
+scope: `components/breadcrumbs.js`  
+type: change  
+rationale: Continue bounded readability refactor by introducing a small route-to-renderer map for simple static branches, reducing conditional-chain length while preserving explicit dynamic branches.
+impact: Refactor-only structural deduplication/readability improvement; no intended route/auth/session/API/EN-CY/a11y behavior change.
+status: completed
+
+Summary:
+
+- Added `getSimpleRouteRenderer(path)` in `components/breadcrumbs.js` for simple routes with no bespoke side effects.
+- Introduced a single invocation block that resolves and renders mapped simple routes when present.
+- Migrated simple route branches into the map, including:
+    - `/myportal`, `/searchresults`, `/advancedsearch`, `/addresssearch`, `/contactus`
+    - `/viewall`, `/myportal/dnsapplications`
+- Preserved existing label text, helper usage, and rendered crumb sequence semantics.
+
+Validation:
+
+- `npx eslint components/breadcrumbs.js` -> pass.
+- `node tests/phase22/index.test.cjs` -> pass (combined suite).
+
+Follow-ups:
+
+- Next slice recommendation: extract a second tiny map for simple "link + text" pair routes (no callbacks, no side effects) to further shrink the conditional chain while keeping callback/dynamic branches explicit.
