Changelog

The Subsystems tab used Border > ScrollViewer which broke scrolling.

The Overview tab uses a bare ScrollViewer directly in Grid.Row="2"

which works correctly. Matched that pattern:

• Removed Border wrapper around ScrollViewer
• ScrollViewer directly in Grid.Row="2" with IsVisible binding
• Padding="24,0,24,32" matching Overview tab exactly

Two issues:

1. "Unknown" group with 5 entries: Plugin SDK calls via TrackedSdkProxy

triggered GetOrCreateState() before DashboardPlugin.CreateViewModelCore

registered the plugin subsystems. The fallback created entries with

DisplayName="Unknown", Category="Unknown".

Fix: GetOrCreateState now infers display name and category from the

subsystem ID pattern. "plugin.privstack.notes" → DisplayName="Notes",

Category="Plugin". Non-plugin IDs get Category="Other" with the raw

ID as name. Register() now uses AddOrUpdate so explicit registration

from DashboardPlugin overwrites auto-created entries with the

authoritative PluginMetadata.Name.

2. Bottom scroll cutoff: Increased ScrollViewer bottom padding from 80

to 120 to clear the macOS dock + app status bar.

The AutoCheckForUpdates setting existed in AppSettings and was wired in

the ViewModel but had no UI toggle — users couldn't disable it. Added a

ToggleSwitch in the About section (same card pattern as Notifications).

Three issues with Subsystems tab accuracy:

1. Status dots: Green only showed for active tasks (task count > 0), so

subsystems with tracked memory but no running task (Crypto/Vault,

Auto-Update, Reminders) showed gray. Now green if tasks > 0 OR

native bytes > 0 OR managed alloc bytes > 0.

2. Plugin activity invisible: Plugins make all data calls through

Host.Sdk.SendAsync, but the shared SdkHost had no subsystem tracking.

Added TrackedSdkProxy that wraps IPrivStackSdk per-plugin — each

PluginHost now gets a scoped proxy tagged with "plugin.<id>". SDK

calls (SendAsync, CountAsync, SearchAsync) enter a subsystem scope,

so navigating to a plugin and loading data shows tracked memory.

3. Reminders allocating with notifications off: The scheduler started

its timer and initial poll unconditionally — PollAsync checked

NotificationsEnabled but already allocated before returning early.

Now guards in Start() itself: if notifications disabled, don't

create the timer or fire the initial poll at all.

The flat list of ~30 subsystem rows was unmanageable and lacked visual

structure. Now grouped by category (Core, AI, Services, UI, Runtime,

Plugin) with each group showing a bold header, item count + active

summary, per-group column headers, and compact item rows.

• New SubsystemGroupViewModel holds category name, summary, and items
• RefreshSubsystemMetrics builds grouped collections instead of flat list
• XAML uses nested ItemsControl: outer for groups, inner for items
• Dropped the redundant Category column from each row (header shows it)
• Tighter row padding (6,8) and smaller font sizes for compact layout
• Inactive dots at 40% opacity for visual hierarchy
• Bottom padding (24,24,24,80) already handles the lower bar overlap
