+### CL-22541-Z4: breadcrumbs post-closure hotfix — callable label resolver parity (static + view-all)
+
+date: 2026-04-09  
+author: Cline  
+scope: `components/breadcrumbs.js`, `tests/phase22/breadcrumbs-route-map-structure.test.cjs`  
+type: change  
+rationale: Fix post-refactor regression where some breadcrumbs rendered blank labels because mapped label entries were returned as function references instead of resolved values.  
+impact: Restores user-visible breadcrumb labels for static and view-all keyed routes; no auth/session/API/security behavior change.
+status: completed
+
+Summary:
+
+- Fixed static text breadcrumb label resolver to invoke mapped label functions:
+    - `getStaticTextCrumbLabel(path)` now resolves callable entries (`resolver ? resolver() : null`).
+- Fixed view-all label resolver parity to support both function-backed and string-backed map entries:
+    - `getViewAllLabel(viewKey)` now invokes function entries and returns string entries directly.
+- Added structure guard assertions to prevent regression of callable label resolution behavior.
+
+Validation:
+
+- `node tests/phase22/breadcrumbs-route-map-structure.test.cjs` -> pass (4/4).
+- `node tests/phase22/index.test.cjs` -> pass (combined suite).
+
+Follow-ups:
+
+- Breadcrumb label resolver parity now aligned across mapped/static/view-all label paths.

+### CL-22541-Z5: architecture comparison overview refresh (senior architecture review)
+
+date: 2026-04-09  
+author: Cline  
+scope: `context/architecture-overview-2026-04-09.md`  
+type: change  
+rationale: User requested a fresh senior architecture review and comparison baseline covering scalability, maintainability, coupling, boundary quality, operational/deployment risk, and prioritized technical debt actions.  
+impact: Documentation-only architecture guidance update; no runtime/auth/session/security/API behavior change.
+status: completed
+
+Summary:
+
+- Added new architecture comparison baseline document:
+    - `context/architecture-overview-2026-04-09.md`
+- Included requested structure:
+    1. current architecture summary
+    2. strengths
+    3. risks (scalability, maintainability, coupling, weak boundaries, operational/deployment)
+    4. prioritized recommendations
+    5. low-risk next improvements
+- Added explicit comparison notes vs existing `context/architecture.md` and identified strategic focus areas for the next modernization wave.
+
+Validation:
+
+- Documentation coherence review against current repo architecture docs (`context/architecture.md`, `context/integration-map.md`, `context/project-overview.md`).
+
+Follow-ups:
+
+- Optionally elevate this architecture overview into a periodic architecture scorecard cadence and add measurable KPIs in memory-bank.
