+Panel Queue handoff implementation was merged from `ticket/panel-queue-orchestrator-sync` into `orchestration/yoi-orchestrator`, then merged into `develop`.
+
+Implemented behavior:
+- Panel Queue performs the root-side Ticket `ready -> queued` mutation and Queue commit.
+- The dedicated orchestration worktree is synchronized with ff-only semantics before Orchestrator notification.
+- Queue success/failure paths report Ticket id, Queue commit, sync result, and notification outcome.
+- Dirty/divergent/state-mismatch/worktree-identity failure cases are blocked with explicit diagnostics.
+
+Validation after merge:
+- `cargo fmt`
+- `cargo test -p client ticket_role`
+- `cargo test -p tui ticket_queue_notification_message_carries_routing_contract`
+- `target/debug/yoi ticket doctor`
+- `cargo check --workspace`
+- `nix build .#yoi`
+- `cargo test -p tui ticket_queue_notification_message_carries_routing_contract`
+
+Cleanup:
+- Removed implementation worktree `/home/hare/Projects/yoi/.worktree/panel-queue-orchestrator-sync`.
+- Deleted merged branch `ticket/panel-queue-orchestrator-sync`.
