Adds a user/MCP-declared task dependency (DependsOnTaskId) distinct from the
planning chain's internal BlockedByTaskId: add_task/update_task can set it,
the queue picker skips a Queued task until the dependency reaches Done, a
Failed/Cancelled dependency leaves the dependent blocked instead of starving
silently, and setting a link rejects self-reference/unknown-id/cycles.
get_task/list_tasks/batch_get_tasks now report blocked/blockedReason, and
wait_for_task_change reports "Blocked" immediately instead of running out its
timeout on a task the picker will never claim.
preview_merge/preview_merge_set gain staleFiles: files a branch touches that
the target branch also changed since the branch's fork point, a more honest
staleness signal than `behind` alone.
## Befund (Batch-Lauf 2026-08-06, Liste "Bandel.Hub")
maxParallelExecutions = 5, 23 Geschwister-Tasks auf demselben Plugin. Die Parallelitaet hat die
Ausfuehrung verkuerzt, aber die Konfliktlast erhoeht: eine CSS-Datei wurde von 10 Tasks
angefasst, drei Razor-Dateien von je 6. Der Engpass des Gesamtdurchlaufs war nicht die
Ausfuehrung, sondern Review und Merge — die sind zwingend seriell. Netto wa

RunInSlotAsync only logged an unexpected exception, leaving a task stuck
Running in the DB forever with the UI never notified (the raw-SQL queue
claim that put it there never broadcasts). Cancellation is handled
separately and left alone, since the cancel path already wrote the
terminal status.
Register(taskId, cts) already refuses (and logs) a double-registration, but
both call sites discarded the bool and dispatched anyway under an
unregistered CTS. If the loser then unregistered the winner's CTS during
its own cleanup, TryCancel could silently no-op against a live process.
- OverrideSlotService.StartInSlot now fails RunNow/ContinueTask loudly
(throws) when it loses the registration race instead of registering
over — or silently proceeding despite losing to — the queue picker.
- QueueService's picker loop retries registration briefly (the loser's own
claim-attempt-then-unregister resolves fast) before dispatching; if
registration never resolves it marks the already-claimed row Failed
instead of running it unregistered.
- RunCancellationRegistry.Unregister already had compare-and-remove
semantics (TryRemove(KeyValuePair)), so a loser's cleanup could not have
removed the winner's CTS once registration correctly failed.
Added regression tests exercising the real registry through both dispatch
paths: RunNow losing the registration race throws without disturbing the
winner, the picker's retry succeeds and TryCancel reaches the live run when
the loser unregisters in time, and the picker fails the task instead of
running unregistered when it never does.
TaskRunner.RunAsync created the worktree (PrepareRunDirectoryAsync)
before claiming Running via StartRunningAsync. RunNow dispatches by
task id with no atomic claim of their own, so a Queued task racing
the queue picker's atomic SQL claim could hit WorktreeManager's
branch-collision self-heal, which force-removes and recreates the
winner's live worktree mid-run.
Move the claim before any resource creation and bail out immediately
when it's rejected. OverrideSlotService.RunNow also fast-rejects a
task already Running in the DB (defense in depth). RunCancellationRegistry
now refuses (and logs) a double registration instead of silently
overwriting the first CTS, so a losing dispatch's cleanup can no
longer unregister the winner's cancellation token.
MaxTimeoutSeconds was 170s against runs that take tens of minutes, forcing
a dozen full-context wait rounds per long-running batch. Raise it to 900s
and raise MCP_TOOL_TIMEOUT in lockstep (ClaudeProcess + every
InteractiveLaunchSpecService launch spec) to 930000ms so the client
connection actually stays open that long instead of aborting first.
Add get_queue_state (QueueStateMcpTools): configured vs. effective
parallel-slot count (via QueueService.GetSlotCountsAsync, extracted from
the former GetEffectiveMaxParallelAsync), active slots with taskId +
startedAt including the run_task_now override slot, and queued tasks in
pick order -- so a caller can observe queue occupancy instead of inferring
it from maxParallelExecutions.
## Kontext: Limits sind Fenster, nicht Summen
Die Runs laufen ueber das Claude-Abo. Limits greifen pro 5h-Fenster und pro 7 Tage. Nicht die Wochensumme tut weh, sondern dass ein Agent-Burst ein Fenster leerraeumt, in dem Mika selbst interaktiv arbeiten will.

Reminders written down as todos had no home: every task looked like Claude work.
A manual task now shows a MANUAL badge and hides send-to-queue, refine and the
planning session; the queue picker, daily prep and the list handler all skip it,
with a TaskStateService guard so the MCP surface and hub cannot start one either.
Opening a hand-driven ConPTY session stays available on purpose.
A list can be marked manual in its settings, which makes tasks created there
(UI and MCP add_task) start out manual. Toggle per task from its context menu.
- CancelAsync now signals the running Claude process of the cancelled task and
its cascaded children via the new RunCancellationRegistry (queue + override
slots register their CTS there) instead of only flipping DB state.
- external MCP review_task 'approve' now mirrors the hub's ApproveReview:
unit merge for parents, ApproveAndMergeAsync for childless tasks, optional
targetBranch; ReviewTaskResult carries mergeStatus/conflicts.
The picker claims Queued->Running atomically before dispatch; the new
StartRunningAsync guard then rejected every queue-dispatched run. Add
alreadyClaimed to RunAsync/ContinueAsync (queue passes true, override
slot keeps the guard) and align the routing tests.

- Clear ReviewFeedback only after a successful re-run so a failed/cancelled
run keeps it for a manual retry.
- Clear stale StartedAt/FinishedAt when rejecting a task back to the queue.
- Only non-planning standalone tasks gate on review (guard PlanningPhase).
- Hide "send to queue" for WaitingForReview tasks so review isn't bypassed.

Standalone tasks now enter WaitingForReview on success; re-queued tasks
carrying reviewer feedback resume the prior Claude session with that
feedback as the next turn.

Add a "Max parallel executions" setting to the General settings tab so
the queue can run more than one task concurrently. QueueService now
tracks multiple active slots and reads the limit from app settings each
cycle, so changes take effect without restarting the worker.

Move interface declarations into per-area Interfaces/ subfolders, merge the
small task-list filter classes into StatusFilter/SmartFlagFilter, and simplify
related services, converters and hub DTO handling.

Queueing a task is itself the explicit "run me" signal — the extra
tag/list filter was redundant and surprised users whose queued tasks
were silently skipped.

Slice 5 of the worker state consolidation refactor.
OverrideSlotService (new in Worker/Queue/) owns RunNow, ContinueTask,
and the override-slot piece of CancelTask. QueueService keeps the
queue-slot guard for "task is already running" rejection and delegates
to OverrideSlotService for execution; CancelTask tries the override
slot first, then the queue slot. QueueSlotState is extracted to its own
file.
Folder reorg (via git mv to preserve history):
- Worker/Queue/ QueueService, OverrideSlotService, QueueSlotState
(alongside existing waker/picker)
- Worker/Lifecycle/ StaleTaskRecovery, TaskResetService, TaskMergeService
- Worker/Worktrees/ WorktreeMaintenanceService
- Worker/Agents/ AgentFileService, DefaultAgentSeeder
Worker/Services/ folder removed. All consumers updated to the new
namespaces (Program.cs, WorkerHub, ExternalMcpService,
PlanningMergeOrchestrator, all Worker tests).
OverrideSlotService is registered as a DI singleton in both the main
worker app and the external MCP app.

Slice 3 of the worker state and queue consolidation refactor.
- Add IQueueWaker / QueueWaker (singleton holding the wake semaphore).
- Add IQueuePicker / QueuePicker; raw SQL UPDATE...RETURNING moves out of
TaskRepository.GetNextQueuedAgentTaskAsync (deleted) and now also filters
on blocked_by_task_id IS NULL and writes started_at on claim.
- TaskStateService takes IQueueWaker directly; the Func<QueueService>
indirection is gone. State transitions to Queued auto-wake the dispatcher.
- QueueService waits via the shared waker and dispatches via the picker.
- Drop explicit _queue.WakeQueue() calls in WorkerHub.QueuePlanningSubtasksAsync
and ExternalMcpService.AddTask. The hub WakeQueue endpoint stays for
diagnostics, delegating to _waker.Wake().
- Migrate tests; pre-existing flaky AppSettings/ExternalMcp tests untouched.
