continue_merge and the parent/children unit-merge drain (PlanningMergeOrchestrator)
re-run the post-merge verify gate but never forwarded their IProgress token into it,
so a slow verify command on either path went silent past Claude Code's 300s MCP
idle-abort even though D1-D3 already fixed this for merge_task/review_task's
childless path. list_worktrees also gets elapsed-time progress: many tracked
worktrees means many concurrent git subprocess spawns.
Worker CLAUDE.md's existing progress rule now points at ProgressReporter as the
one implementation instead of a fresh polling loop.
The merge commit message was hand-rolled per caller ("Merge task: <title>",
"Merge <branch>", "Merge subtask") and ignored the task's commit type. Every
caller now passes a blank message and TaskMergeService fills in
CommitMessageBuilder.BuildMerge -> {commitType}(list-slug): merge <title> plus the
ClaudeDo-Task trailer; the merge modal prefills it from GetMergeTargets.
A merge whose list has a verify command holds the MergeTask call for minutes (5m46s
on this repo), during which the modal only disabled its button - no spinner, no
message, so a landed merge looked like a dead app. TaskMergeService now broadcasts
MergeProgress(taskId, phase, elapsedSeconds) for the merging and verifying phases
(re-reported every 30s) plus a WorkerLog line when verify starts; the modal shows a
spinner and the localized phase.
TaskStateService.CancelAsync allowed cancelling a WaitingForReview task
even while PlanningMergeOrchestrator was mid-drain on it: ApproveReview
awaits the whole multi-subtask merge synchronously, so a concurrent
CancelReview (UI or MCP) could flip the parent to Cancelled while the
orchestrator kept merging children onto the target branch, then
FinalizeParentDoneAsync would find the parent no longer WaitingForReview
and give up - leaving the merged diffs stranded with no rollback.
CancelAsync now rejects with a clear reason when HasActiveMerge(taskId)
is true. TaskStateService can't take PlanningMergeOrchestrator as a
direct constructor dependency (circular back to ITaskStateService), so
it takes a lazily-resolved Func<IActiveMergeState> instead, mirroring
the existing Func<ITaskStateService> cycle-break already used for
PlanningChainCoordinator.
UI polish: DetailsIslandViewModel.IsMergeDraining gates
CancelReviewCommand's CanExecute (same shape as
WorktreesOverviewModalViewModel.IsMerging), and the command's catch now
raises ErrorReported instead of swallowing the rejection silently.
review_task/continue_merge on a planning parent always leaves conflicts in
the tree, and the UI auto-opened the resolver on every PlanningMergeConflict
broadcast regardless of who started the merge -- so a running Claude session
resolving a unit-merge conflict could race a human editing the same shared
checkout in a resolver window neither of them asked for.
PlanningMergeOrchestrator.StartAsync now takes an externallyDriven flag (set
by ExternalMcpService's MCP-driven review_task path, left false for the UI's
ApproveReview) that rides along on the PlanningMergeConflict broadcast. The
UI only auto-opens the resolver when it's false; otherwise it shows a
persistent banner with a manual "Open resolver" button, cleared on
PlanningMergeAborted/PlanningCompleted. A new GetActiveExternalConflictsAsync
query (checked against GitService.IsMidMergeAsync rather than the in-memory
flag alone) lets the UI resync the banner on reconnect instead of trusting a
one-shot broadcast that isn't replayed after a restart.
The childless single-task conflict path was checked and needed no change --
it only broadcasts the generic TaskUpdated, never PlanningMergeConflict.
HasChangesAsync counted untracked files, so a stray file in the shared
target working dir (e.g. left by a concurrent session) blocked merge
preflights even though nothing tracked changed. Add an includeUntracked
overload defaulting to true, and pass includeUntracked: false only from
the two target-working-tree merge preflights (TaskMergeService.MergeAsync,
PlanningMergeOrchestrator.StartAsync). Auto-commit and the worktree
cleanup data-loss guard keep counting untracked files, since those
callers need to know about them.
PlanningMergeOrchestrator._states is in-memory. A worker restart during a
conflict pause left the list repo mid-merge with no recovery path: both
ContinuePlanningMerge and AbortPlanningMerge threw "no in-progress merge",
and re-Approving failed on the IsMidMergeAsync guard.
AbortAsync now falls through to a stateless path when no _states entry exists:
it looks up the parent's list WorkingDir and, if the repo is mid-merge, runs
git merge --abort there directly, then broadcasts PlanningMergeAborted.
Parent remains WaitingForReview — the next Approve restarts the unit merge
(already-Merged child worktrees are skipped as before).
ContinueAsync error message now points to AbortPlanningMerge as the recovery
action. StartAsync mid-merge guard also carries an actionable hint.
Tests: AbortAsync stateless + mid-merge (restart recovery), AbortAsync
stateless + clean repo (clear error).

Replaces the direct EF Status write in PlanningMergeOrchestrator with
_state.ApproveReviewAsync, enforcing the TaskStateService invariant as
sole owner of Status writes. Handles the improvement-parent path where
TaskMergeService already approved the parent's own worktree during the
drain (status == Done on entry → still success). If the parent was
concurrently cancelled, the transition guard rejects the approve,
PlanningCompleted is not broadcast, and the cancelled status is
preserved. ApproveReviewAsync now also sets FinishedAt.

- UnifiedDiffParser detects added/deleted/renamed/binary files; diff
modal shows a file list, binary/empty placeholders, and can diff a
merged task by commit range after its worktree is gone
- DetailsIslandViewModel flags children needing attention (failed,
cancelled, awaiting review, or with roadblocks) on the parent
- GitService gains worktree head-commit/range support; planning chain,
merge orchestration, and session manager tweaks with updated tests
- refresh app/installer/worker icons

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.
