+## Sprint 37 Cx-2 Gap Audit
+
+The 2026-05-18 GitHub workflow scan found these remaining repos with
+`runs-on: [self-hosted, linux, fc-build-linux]` but no K8s runner Deployment:
+`FlowerCore.AiStation.Linux`, `FlowerCore.PHP`, `FlowerCore.PiManager`,
+`FlowerCore.Shared.Barcodes`, `FlowerCore.Shared.Lookup`,
+`FlowerCore.Shared.Nodes`, `FlowerCore.Shared.PrintClient`,
+`FlowerCore.Shared.Relay`, `FlowerCore.Shared.ShowRunner`, and
+`FlowerCore.Shared.Storage`.
+
+Mixed/platform repos also have Linux workflow legs but need owner review before
+adding Linux runner Deployments: `FlowerCore.Library.Mac`,
+`FlowerCore.Signage.Agent.AppleTv`, and `FlowerCore.Signage.Player.Wpf`.
