Changelog

CommunityToolkit's AsyncRelayCommand disables the command while it's

executing, preventing concurrent calls. In client mode, SelectTab awaits

plugin.OnNavigatedToAsync() which makes HTTP SDK calls to the server —

these are much slower than local FFI calls. While the first SelectTab

is waiting on the HTTP response, all sidebar buttons bound to the same

SelectTabCommand are disabled (greyed out) because CanExecute returns

false during execution.

Fix: AllowConcurrentExecutions = true on SelectTab, matching the

expected behavior where rapid tab switching should always work.

Also fix HttpSdkTransport stale logger (same pattern as PluginRegistry:

static readonly ForContext becomes dead after ReconfigureForWorkspace).

Extract Models/ (16 files) and Services/ (16 files) from the Tasks

plugin into a new PrivStack.Plugin.Tasks.Headless project. This

assembly references only PrivStack.Sdk — zero Avalonia dependency —

making it loadable by the headless server.

New files in Headless:

• TasksHeadlessPlugin.cs: HeadlessPluginBase entry point with entity

schemas, service initialization, and IApiProvider implementation

• TasksApiHandler.cs: Shared API handler extracted from

TasksPlugin.Api.cs — used by both desktop and headless plugins

The UI plugin (PrivStack.Plugin.Tasks) now references the Headless

project for shared models and services. TasksPlugin.Api.cs delegates

to the shared TasksApiHandler.

Directory.Build.props updated: HeadlessPlugin=true opt-out prevents

UI.Adaptive (and thus Avalonia) from being added as a transitive

dependency to headless plugin projects.

AXAML xmlns declarations updated with assembly qualifier for types

now in the Headless assembly.

Calendar 1.14.7→1.14.8, Canvas 1.0.4→1.0.5, Contacts 1.9.6→1.9.7,

Data 1.21.0→1.21.1, Email 1.28.1→1.28.2, Files 1.11.0→1.11.1,

Finance 3.24.1→3.24.2, Habits 1.2.3→1.2.4, Journal 1.15.5→1.15.6,

Notes 1.65.1→1.65.2, WebClips 1.3.4→1.3.5. Both csproj and

PluginMetadata versions updated.

PluginLoadContext now resolves assemblies from sibling plugin directories

when the plugin's own directory and host don't have them. This fixes the

Tasks plugin failing to load in client mode with FileNotFoundException

for PrivStack.Plugin.Tasks.Headless — the Headless DLL is deployed to

its own sibling directory (plugins/PrivStack.Plugin.Tasks.Headless/)

and the Tasks plugin depends on it for shared models and services.

Also guard Emergency Kit regeneration in client mode — SetupRecovery()

requires the native runtime which isn't initialized when running as a

client. Shows a clear message directing users to the server instance.

Migrate Journal, Finance, Habits, WebClips, Canvas, Data, and Email

from local ErrorMessage/StatusMessage patterns to the shell's unified

IToastService. Email was the most involved — removed _errorMessage

ObservableProperty, ClearStatusAfterDelay helper, and converted all

ErrorMessage/StatusMessage completion notifications across 8 partial

class files to _toast?.Show() calls. StatusMessage retained for

in-progress indicators (sync status text). Sub-ViewModels (Compose,

AccountSetup, AccountSettings) keep their own ErrorMessage for inline

form validation.
