Ein Task kann jetzt auf beliebig viele Vorgaenger warten. Die Einzelspalte
tasks.depends_on_task_id wird durch die Beziehungstabelle task_dependencies
ersetzt (Composite-PK, beide FKs ON DELETE CASCADE -- das reproduziert das
alte ON DELETE SET NULL: geloeschter Vorgaenger = Kante weg = Task wieder
pickbar). BlockedByTaskId bleibt unberuehrt.
- Migration AddTaskDependencies kopiert jede bestehende depends_on_task_id
verlustfrei in die Tabelle, bevor die Spalte fallengelassen wird
- QueuePicker gatet per doppelt negiertem NOT EXISTS: kein Task mit 0 Kanten
wird blockiert, alle Kanten muessen done sein, eine Kante auf einen
verschwundenen Task blockiert weiter
- SetDependsOnAsync ersetzt die ganze Menge; Zykluspruefung ist jetzt eine
BFS ueber den Graphen, faengt also auch A->B->C->A
- blockedReason nennt alle offenen Vorgaenger (External/TaskBlocking, von
ExternalMcpService und TaskWaitMcpTools gemeinsam genutzt)
- add_task/update_task nehmen dependsOnTaskIds; die alte Skalarform bleibt
als Ein-Element-Menge inkl. ""-Clear-Sentinel gueltig
- UI: Fan-in-Zeile bleibt flach und listet alle Vorgaenger im After-Label,
die lineare Kette rendert unveraendert
The 4s reconcile tick was added to three long-lived surfaces. On two of
them it reloads by rebuilding every row instance, which silently threw
away whatever the user had built up since the overlay opened; on the
third it healed a row's data but left it in the wrong section.
- WorktreesOverview: LoadAsync clears Rows, SelectedCount, ConflictRows
and BatchProgress, so batch-merge ticks, the highlighted row and a
finished batch's outcome badges were wiped every four seconds --
assembling a multi-worktree selection was impossible. Carry that state
across the reload, keyed by task id, and re-point SelectedRow at the
fresh instance (or clear it when the worktree is gone).
- MergeHelperSelection: the remember/restore had no re-entrancy guard, so
a second tick entering between the first one's reload and its restore
snapshotted rows already back at IsTickedByDefault and wrote that
default back, re-ticking what the user had unticked. One tick at a time,
and hold the row instances instead of a value snapshot so a tick landed
during the await survives.
- TasksIsland: the tick deliberately never called Regroup because Phase 2b
owned Rows in parallel. 2b has landed, so a healed task that went Done
stayed in the Open section under a stale count, and a healed depends-on
link never pulled its dependent under the chain head. Regroup when a
patch moved a grouping input, gated on a cheap key so an idle tick stays
free.
The task-numbers slice added a UNIQUE index on tasks.number. Ui.Tests seed
TaskEntity rows directly instead of going through TaskRepository, so every row
kept the default Number = 0 and 31 tests failed with
'UNIQUE constraint failed: tasks.number'.
TasksIslandViewModel now runs a periodic tick that diffs the flat Items
collection against SQLite and patches properties in place (capped at 500
rows, sharing the Phase 1 delta sequence guard so it never overtakes a
fresher broadcast). Never rebuilds rows or triggers Regroup/LoadForList, so
it stays decoupled from the parallel Phase 2b virtualization work. The same
cadence now refreshes the long-lived Worktrees Overview, Log Visualizer, and
Merge Helper selection overlays; short-lived modals are untouched.
