The pill never appeared because:
1. SwiftUI .frame(width:0, height:0) when idle poisoned fittingSize
2. AppKit constraints locked at 0x0 prevented expansion on state change
3. fittingSize always returned 0 due to active 0x0 constraints
Fix: Remove zero-frame from SwiftUI (always render at natural size,
use opacity only). Deactivate constraints before measuring fittingSize
so they don't clamp the measurement. Pass visibility to sizeToolbarItem
to set constraints to zero when idle or natural size when active.
@Published fires on willSet, so the Combine sink measured fittingSize
while SwiftUI still saw the old state (idle/EmptyView), getting 0x0.
Defer measurement to next run loop cycle so SwiftUI processes the
new state before we read fittingSize.
- Fix auto-updating Text(date, style: .time) causing continuous SwiftUI updates
by using static formatting with .formatted(date:time:)
- Fix notification popover keeping SwiftUI observers active when closed by
clearing contentViewController on popover close and recreating on open
- Fix focus loss when notifications arrive while typing by only setting
focus in NotificationsPage when the page is visible
- Make Update Pill and Update Logs debug-only features
- Add CPU regression tests: test_cpu_usage.py, test_cpu_notifications.py
- Add lint test for auto-updating Text patterns: test_lint_swiftui_patterns.py
