Usability-Audit 2026-09-10 found three gaps versus the dependency-chain-display
spec: a Queued task blocked on an unmet task_dependencies edge rendered the same
chip as one about to run, a cross-list predecessor silently dropped the
"after #N" chip, and the detail pane showed nothing about a wait at all.
- TaskRowViewModel gains IsBlockedByDependency/DependencyWaitLabel (extrinsic,
assigned by TasksIslandViewModel like the existing chain fields); IsQueued/
IsWaiting/StatusChipClass/StatusLabel/StatusChipTooltip now account for it
alongside the existing BlockedByTaskId planning-chain link.
- TasksIslandViewModel.ApplyDependencyWaitState computes the blocked flag and
wait label per row; a new RefreshExternalDependencyCacheAsync backfills
Number/Title/Status for predecessors not loaded into the current list's
Items (reusing the already-open DbContext, no new hub method), so
BuildAfterLabel/blocking both resolve a listenfremder Vorgänger correctly.
- New "waiting" chip style (IslandStyles.axaml) and locale keys (en+de);
TaskHeaderBar shows a "Waiting on #N" line bound straight to the same row.
Tests: TasksIslandChainTests (blocked/unblocked chip, cross-list predecessor),
DetailsIslandDependencyWaitTests (new), TaskRowViewModelNotificationsTests
updated for the new notification set.
