+## Plan
+
+Implementation routing accepted and worktree created.
+
+Worktree plan:
+- Branch: `shutdown-intake-pod-after-ready-idle`
+- Worktree: `.worktree/shutdown-intake-pod-after-ready-idle`
+- Base: `64318e8 ticket: route intake idle shutdown implementation`
+- Scope: implement transient post-idle shutdown for actual Ticket Intake Pods after successful `TicketIntakeReady`.
+
+Delegation plan:
+- Spawn sibling coder Pod with write scope limited to `.worktree/shutdown-intake-pod-after-ready-idle`.
+- Coder must run Bash commands from the child worktree, not from the main workspace.
+- Coder must not edit main-workspace `.yoi` / Ticket / workflow / docs records, and must not create generated memory/local/runtime/secret-like files.
+- Reviewer will be spawned read-only after coder reports diff/commits and validation evidence.
+
+Concurrency note:
+- `allow-spawnpod-child-workspace-cwd` remains active in a separate worktree/fix-loop. This implementation must remain isolated and should not depend on the unmerged `SpawnPod.cwd` work.
+
+Stop/completion policy:
+- Because the human authorized cleanup after completion, this Orchestrator will proceed through reviewer approval, merge-completion validation, Ticket close, Pod stop, worktree removal, and branch deletion if the branch is approved and merge authority remains clear.
