+## Implementation report
+
+Integration report:
+
+Merged implementation branch into orchestration branch:
+- branch: `impl/00001KV4ZPAD3-panel-row-hierarchy`
+- implementation commit: `f3b435e7 fix: clarify panel ticket row hierarchy`
+- merge commit: `8c00a6e9 merge: panel row hierarchy`
+
+Reviewer result:
+- `approve` recorded from `yoi-reviewer-00001KV4ZPAD3`.
+
+Validation in Orchestrator worktree `/home/hare/Projects/yoi/.worktree/orchestration`:
+- Passed: `cargo test -p tui workspace_panel --lib`
+  - 16 passed
+- Passed: `cargo test -p tui panel_ticket --lib`
+  - 4 passed
+- Passed: `cargo test -p tui selected_ticket_intake_child_status --lib`
+  - 1 passed
+- Passed: `cargo fmt --check`
+- Passed: `git diff --check`
+
+Notes:
+- Broader `cargo test -p tui multi_pod --lib` remains affected by unrelated workspace-context tests and was not used as a blocker.
+- Ticket/Intake visual hierarchy improved without lifecycle/action/schema/polling/spawn semantic changes.
+- Orchestrator worktree is clean after validation.
+
+Cleanup planned:
+- Stop related coder/reviewer Pods.
+- Remove only child implementation worktree/branch for this Ticket.
