Changelog

Introduces IQuickActionForm capability interface with CloseRequested event and

RequestClose() method, enabling the shell to handle overlay close lifecycle

instead of each plugin using reflection to find MainWindowViewModel. The

QuickActionService now subscribes to IQuickActionForm.CloseRequested when

creating UI content, providing a standardized close path. ShowQuickActionOverlay

resets stale state before showing new content and dispatches via

Dispatcher.UIThread.Post to ensure a clean visual tree cycle when rapidly

re-invoking overlays.

The orphan entity detection compared created_by (a peer UUID identifying

the device) against plugin_id (e.g. "privstack.notes"), which never

matched — causing every entity to be classified as an orphan and deleted.

Fixed find_orphan_entities and delete_orphan_entities to check only the

entity_type column against the set of registered entity types from all

plugins. The created_by field is a peer identifier for CRDT sync and is

not related to plugin ownership.

Rust core v1.13.6, Desktop v1.49.1.

Replaced the horizontal StackPanel layout with a Grid so the shortcut

badge is pushed to the far right of the search pill. Made the badge

bold and bumped font size from ThemeFontSizeXs to ThemeFontSizeSm for

better visibility. The badge is now vertically centered with proper

right margin, clearly separated from the placeholder text.

Merges the shell's intent suggestion tray and plugin-local AI panels into a

single global "AI Suggestions" tray owned by the desktop shell.

New files:

• AiSuggestionServiceImpl: wraps WeakReferenceMessenger for Push/Update/Remove
• AiSuggestionTrayViewModel: subscribes to IntentEngine events + content

suggestion messages, aggregates both card types into one ObservableCollection

• ContentSuggestionCardViewModel: wraps ContentSuggestionCard, sends

ActionRequested/Dismissed messages back to owning plugin

• IAiTrayCardViewModel: common interface for Intent and Content card VMs
• AiSuggestionTray.axaml: DataTemplate-based rendering for both card types

Removed:

• IntentSuggestionTrayViewModel (replaced by AiSuggestionTrayViewModel)
• IntentSuggestionTray.axaml (replaced by AiSuggestionTray.axaml)

Renamed in MainWindowViewModel:

• IntentTrayVM → AiTrayVM, IsIntentTrayOpen → IsAiTrayOpen
• ToggleIntentTray → ToggleAiTray

Updated MainWindow.axaml bindings, Keyboard.cs escape handler, PluginHost/

PluginHostFactory wiring, and ServiceRegistration DI container.

Desktop version 1.48.3 → 1.49.0.

Introduces the SDK contract for the global AI suggestion tray:

• ContentSuggestionCard, SuggestionAction, ContentSuggestionState models
• Messenger messages: Push/Update/Remove/ActionRequested/Dismissed
• IAiSuggestionService interface (Push, Update, Remove)
• IPluginHost.Suggestions property for plugin access
• SDK version bump 1.48.0 → 1.49.0

Plugins can now push content suggestion cards (summaries, rewrites, etc.)

into a shell-owned unified tray via Host.Suggestions. Action clicks route

back to the owning plugin via ContentSuggestionActionRequestedMessage on

the messenger bus, keeping block-level operations inside the plugin while

the shell renders cards uniformly alongside intent suggestion cards.
