  Team update (2026-02-25): M12 introduces Migration Analysis Tool PoC (`bwfc-migrate` CLI, regex-based ASPX parsing, 3-phase roadmap)  decided by Forge
 
+## Summary: Issue #358 — 5 Missing Smoke Tests (2026-02-25)
+
+Added 5 missing smoke test InlineData entries to ControlSampleTests.cs covering all gaps identified in M9 audit: ListView/CrudOperations, Label, Panel/BackImageUrl, LoginControls/Orientation, DataGrid/Styles. All 5 sample pages verified to exist. Tests added as InlineData to existing Theory methods (EditorControl, DataControl, LoginControl). Build verified green (0 errors).
+
+## Learnings
+
+- Panel/BackImageUrl sample page uses external placeholder URLs (`via.placeholder.com`). The existing `VerifyPageLoadsWithoutErrors` filter for "Failed to load resource" handles this, so the smoke test works despite the team convention against external image URLs.
+- LoginControls/Orientation is at `/ControlSamples/LoginControls/Orientation` (not under `/ControlSamples/Login` or `/ControlSamples/ChangePassword` as initially suggested in the issue).

+# Decision: All 5 Missing Smoke Tests Added (Issue #358)
+
+**Decided by:** Colossus  
+**Date:** 2026-02-25
+
+## Context
+
+M9 audit identified 5 sample pages without smoke tests. Issue #358 requested adding them.
+
+## Decision
+
+Added 5 InlineData entries to existing Theory smoke tests in `ControlSampleTests.cs`:
+
+| Page | Theory Method | Route |
+|------|--------------|-------|
+| ListView CrudOperations | `DataControl_Loads_WithoutErrors` | `/ControlSamples/ListView/CrudOperations` |
+| Label | `EditorControl_Loads_WithoutErrors` | `/ControlSamples/Label` |
+| Panel BackImageUrl | `EditorControl_Loads_WithoutErrors` | `/ControlSamples/Panel/BackImageUrl` |
+| LoginControls Orientation | `LoginControl_Loads_WithoutErrors` | `/ControlSamples/LoginControls/Orientation` |
+| DataGrid Styles | `DataControl_Loads_WithoutErrors` | `/ControlSamples/DataGrid/Styles` |
+
+## Notes
+
+- All 5 sample pages confirmed to exist at their routes.
+- Panel/BackImageUrl uses external placeholder URLs — smoke test works due to existing "Failed to load resource" filter, but the page should be updated to use local images per team convention.
+- No new Fact tests needed; all fit cleanly as InlineData on existing Theory methods.
+- Build verified green.
