+## Sprint 26 End Refactor Pass (Architecture Compliance)
+
+Performed a dedicated post-sprint refactor pass focused on maintainability and
+architecture-rule alignment without behavior changes.

+**Refactors applied:**
+- `editor/src/CompletionOverlayUXHardening.h`
+  - extracted shared helpers for clamping/index wrapping
+  - removed duplicated inline clamp/wrap logic
+- `editor/src/NotificationStatusRefresh.h`
+  - factored repeated style construction into `makeStyle(...)`
+  - reduced duplicated initializer literals
+- `editor/src/CrossPanelConsistencySweep.h`
+  - centralized drift recording in `recordDrift(...)`
+  - reduced repeated pass/fail mutation logic
+
+**Architecture compliance audit:**
+- Header size gate: PASS (`<=600` across audited sprint files)
+- `goto` usage in runtime path: PASS (none in Sprint 26 modules)
+- Stale TODO markers in Sprint 26 modules: PASS
+- Header-only pattern for Sprint 26 additions: PASS
+
+**Refactor verification run:**
