Changelog

The HandleUpdateTaskAsync and HandleUpdateProjectAsync handlers were

passing the partial PATCH body directly as the SdkAction.Update payload.

Since the SDK treats Update as a full replacement, sending e.g.

{"status":"done"} would wipe title, description, and all other fields.

Added MergeWithExistingAsync helper that reads the current entity,

overlays the PATCH fields on top, and sends the merged result. This

gives proper partial-update (PATCH) semantics to both /tasks/{id} and

/projects/{id} endpoints.

• Settings overlay: add delete button (x) to each custom field row
• Settings overlay: replace static List/Card badges with interactive

ToggleButtons that persist ShowInList/ShowInCard via UpdateAsync

• Detail panel: add Custom Fields section between Notes and Linked Items,

showing name-value pairs bound to SelectedTaskCustomFields

• ViewModel: parameterize DeleteFieldCommand to accept field directly,

add ToggleFieldVisibilityCommand with "list:{id}" / "card:{id}" format

The TasksSettingsOverlay was missing the StyleInclude for the local

ModalOverlayTheme.axaml. Without this ControlTheme, the ModalOverlay

TemplatedControl had no visual template — clicking the settings cog

set IsOpen=true and made the UserControl visible, but the overlay

rendered as an empty box with no backdrop, card, or content.

The GitHubIssueSourcesOverlay had the correct StyleInclude but it

was never added to TasksSettingsOverlay when it was created.

Note: Build may fail at this commit due to concurrent in-progress

work by another session (CS0136 variable shadowing in

TasksViewModel.cs:2421) — will be resolved in a subsequent commit.

Notes: TrashPageAsync, TrashPageFromTreeAsync, DeletePagePermanentlyAsync,

and EmptyTrashAsync now prompt for user confirmation before proceeding.

Tasks: DeleteTaskByItem, DeleteTask, and BulkDelete converted from void

to async Task and now prompt for confirmation. DialogService wired in

TasksPlugin.CreateViewModelCore.

Calendar: DeleteEventByIdAsync now prompts for confirmation on the

non-recurring path (recurring events already have their own dialog).

Fixes polish audit bugs #22, #23, #49, #69.

All sync operations now run on background threads so the UI stays

responsive. Events populate incrementally as each subscription

completes rather than blocking until everything finishes.

CalendarSyncService:

• SyncAllAsync runs subscriptions concurrently (bounded by

MaxConcurrency=8) instead of sequentially. Each subscription

fires SyncCompleted on completion for incremental UI refresh.

• Background timer loop (RunAsync) uses the same concurrent pattern

instead of sequential foreach.

CalendarViewModel:

• SyncAllCalendars fires sync on Task.Run and returns immediately.

SyncCompleted event (already wired via Dispatcher.UIThread.Post

in CalendarPlugin) handles the refresh.

AddSubscriptionViewModel:

• ICS and CalDAV subscription creation closes the dialog immediately

after persisting the subscription. Initial sync fires in background

via Task.Run — no more blocking the UI while the first fetch runs.
