+## Decision
+
+Implementation follow-up accepted。
+
+Evidence rechecked before side effects:
+- Ticket remains `queued` and has prior implementation-ready IntentPacket / accepted plan。
+- `TicketRelationQuery(00001KXK9507N)`: 0 blockers。
+- `TicketOrchestrationPlanQuery(00001KXK9507N)`: accepted plan exists for branch/worktree `work/00001KXK9507N-ticket-workspace-settings` / `/home/hare/Projects/yoi/.worktree/00001KXK9507N-ticket-workspace-settings`。
+- `TicketList(inprogress)`: 0 件。
+- Orchestrator worktree is clean。
+- No existing `00001KXK9507N` worktree/branch was reported in the recheck。
+
+Next action:
+- Record `queued -> inprogress` now, then create the dedicated implementation worktree and route implementation to sibling Coder Pod。
+- Per current user instruction, do not call `StopPod` during later cleanup。

+## State changed
+
+Explicit follow-up authorized implementation start. Ticket/relation/plan/worktree state was rechecked and no blockers were found. Moving to inprogress before worktree creation or role Pod spawn.
