## Prioritised Topics to Be Actioned

| Priority | Topic | Date noted | Next step | Notes |
|---|---|---|---|---|
| P1 | Prevent synchronous and asynchronous execution from overlapping in `SaProcess_Base` | 2026-09-09 | Route `RunProcess()` and `RunAsync()` through one guarded start operation and extend the lifecycle tests. | A synchronous call can currently reuse and dispose the asynchronous worker's task data. |
| P2 | Retain cancellation as a completed process outcome | 2026-09-09 | Store a durable cancellation result until the next process reset and test post-completion state. | `IsInterrupted` currently loses token-based cancellation after task-data cleanup. |
| P2 | Handle `OperationCanceledException` as cancellation | 2026-09-09 | Catch cancellation separately in `RunProcess()` and avoid recording it as an error. | The general exception handler currently consumes cancellation before `RunAsync()` can distinguish it. |
| P2 | Observe background `RunAsync()` tasks in consumers | 2026-09-09 | Review downstream fire-and-forget call sites and give their process consoles ownership of the returned task. | Rebuilt consumers are binary-compatible, but some source call sites still discard the task. |
| P3 | Define disposal and cross-thread status semantics | 2026-09-09 | Decide whether to add asynchronous disposal and a synchronized process-status snapshot. | Disposal currently requests cancellation without awaiting termination; several status properties are read across threads. |

## Project-Specific Trackers

- [`SacsMobileMaui`](../SacsMobileMaui/docs/topics.md) tracks the MAUI framework upgrade, UI-thread helpers, native handlers, controls, and resources.

## In-Progress Topics

| Priority | Topic | Date noted | Date started | Next step | Notes |
|---|---|---|---|---|---|
| P1 | Review and harden `SaProcess_Base` lifecycle and cancellation | 2026-09-08 | 2026-09-08 | Address the prioritised Process Base findings above, beginning with prevention of mixed synchronous/asynchronous execution. | Task ownership, timeout retention, cancellation lock ordering, documentation, and initial lifecycle tests are complete. Cooperative polling in individual derived processes will be handled separately. |

## Completed Topics

| Topic | Date noted | Date started | Date completed | Outcome |
|---|---|---|---|---|
| Make asynchronous Process Base execution awaitable and retain state after a stop timeout | 2026-09-08 | 2026-09-08 | 2026-09-08 | `RunAsync()` returns `Task`; `StopProcessAsync()` reports success and leaves active state owned by a worker that has not stopped. |
| Remove cancellation callbacks from the Process Base lifecycle lock | 2026-09-08 | 2026-09-08 | 2026-09-08 | Cancellation and task-data disposal use separate synchronization; worker cleanup detaches state before disposal. |
| Add Process Base lifecycle tests | 2026-09-08 | 2026-09-08 | 2026-09-08 | Five focused MSTest cases cover completion, duplicate starts, stop timeout retention, cooperative cancellation, and cancellation callback lock behavior. |
