Review found compatibility API debt, UI-thread synchronization defects, incorrect handler casts, an `AllowInvalid` setter bug, and discarded resource streams. Local validation was limited by an inconsistent installed workload manifest and write-protected existing `obj` output. |

Windows and Android Debug builds pass with zero errors. Nullable picker changes are handled while preserving the controls' existing non-null public API. Compatibility API, UI-thread synchronization, handler-cast, `AllowInvalid`, and resource-stream work remains tracked. |

 ## Prioritised Topics to Be Actioned
 
 | Priority | Topic | Date noted | Next step | Notes |
 |---|---|---|---|---|
-| P1 | Repair the MAUI workload and capture the pre-migration mobile baseline | 2026-09-10 | Repair the inconsistent Android workload manifests, select the current SDK explicitly, then restore/build Windows and Android and record Apple-platform validation requirements. | Depends on a usable MAUI toolchain and authoritative consumer source control. The current workload reports a missing `microsoft-net-runtime-android-net9` extension; Apple builds require a compatible Mac/Xcode environment. |
+| P1 | Upgrade Sandtrap and Sandalwood to .NET MAUI 10 | 2026-09-10 | Retarget and align each consumer with `SacsMobileMaui`, then build and smoke-test their supported platforms. | The shared library now targets .NET 10 and MAUI 10.0.20. Sandalwood and Sandtrap still require coordinated consumer migrations before Common can remove its temporary .NET 8 targets. |
-| P1 | Upgrade `SacsMobileMaui` and its consumers from unsupported .NET MAUI 8/9 to .NET MAUI 10 | 2026-09-10 | Replace MAUI 9 compatibility APIs, align and validate consumer projects, then retarget to `net10.0` and the current MAUI 10 servicing release. | MAUI 9.0.120 is the final MAUI 9 patch, but MAUI 9 support ended on 2026-05-12. Sandalwood and Sandtrap still target MAUI 8 while referencing the `net9.0` shared project. The shared library also uses removed/deprecated compatibility layouts, `Frame`, `MainPage`, and popup APIs. |
+| P2 | Replace obsolete MAUI compatibility APIs | 2026-09-10 | Replace compatibility layouts, `Frame`, `MainPage`, synchronous popup calls, and deprecated expansion options; then remove `Microsoft.Maui.Controls.Compatibility`. | The .NET 10 Windows and Android builds succeed, but retain compatibility references and report the existing API-obsolescence warnings. |
 | P1 | Make `SamThreadUtil` and form dialogs genuinely asynchronous and deadlock-safe | 2026-09-10 | Replace synchronous UI-thread bridges with `Task`-returning APIs, update the Sandtrap caller, and add focused tests. | The void `InvokeOnMainThreadSync` overload never waits; the generic overload and `DisplayConfirmSync` block on `Task.Result` and can deadlock on the UI thread. `DisplayAlertSync` also passes an async lambda to `Action`, producing `async void` behavior. |
 | P2 | Correct MAUI native handler type checks | 2026-09-10 | Use `SamEditor` in editor mappings and `SamPicker` in picker mappings; validate each platform-specific option. | Several editor and every picker option currently cast to the wrong custom control type, so configured native styling is silently skipped. |
 | P2 | Fix `SamDatePicker.AllowInvalid` state transition | 2026-09-10 | Change the assignment in the equality guard, verify both transitions, and add tests for display and reset behavior. | Setting `AllowInvalid` to `true` returns before refreshing the control; the guard uses `allowInvalidDate = value`. |

-| P1 | Establish authoritative source control for Sandtrap and Sandalwood | 2026-09-10 | 2026-09-10 | Review each initial import, configure its intended remote, and create the baseline commit. | Separate Git repositories now exist at `PippinApps/Repositories/Sandtrap` and `PippinApps/Repositories/Sandalwood`; baseline guidance and tracking files have been added. Consumer migration work should begin only after their initial imports are safely committed. |

+| Establish authoritative source control for Sandtrap and Sandalwood | 2026-09-10 | 2026-09-10 | 2026-09-10 | Separate repositories were initialized, given baseline guidance and tracking files, committed, and pushed to their remotes. |
+| Repair the MAUI workload and validate local targets | 2026-09-10 | 2026-09-11 | 2026-09-11 | SDK 10.0.401 reports coherent .NET 10 Android, iOS, Mac Catalyst, and MAUI Windows workloads. The upgraded shared project restores and builds successfully for Windows and Android; Apple builds still require compatible Mac/Xcode validation. |
+| Upgrade `SacsMobileMaui` to .NET MAUI 10 | 2026-09-10 | 2026-09-11 | 2026-09-11 | Retargeted Android, iOS, Mac Catalyst, and Windows to .NET 10; aligned MAUI packages to 10.0.20; and adapted date/time controls to MAUI 10 nullable picker values. Windows and Android Debug builds complete with zero errors. |
