+## Implementation report
+
+Integration report:
+
+Merged implementation branch into orchestration branch:
+- branch: `impl/00001KV5D7MG5-panel-orchestration-overlay`
+- implementation commit: `e0ddbed1 feat: show orchestration ticket overlay in panel`
+- merge commit: `eeb6986f merge: panel orchestration overlay`
+
+Reviewer result:
+- `approve` recorded from `yoi-reviewer-00001KV5D7MG5`.
+
+Validation in Orchestrator worktree `/home/hare/Projects/yoi/.worktree/orchestration`:
+- Passed: `cargo test -p tui workspace_panel --lib`
+  - 21 passed
+- Passed: `cargo check -p tui --all-targets`
+- Passed: `cargo fmt --check`
+- Passed: `git diff --check`
+
+Notes:
+- Overlay is read-only and source-qualified.
+- Current branch Ticket state remains primary authority and is not overwritten.
+- Missing worktree / branch mismatch / unrelated repo safety paths are covered by focused tests.
+- Queue/Start-like duplicate actions are suppressed when overlay shows `inprogress` or `done`.
+- Orchestrator worktree is clean after validation.
+
+Cleanup planned:
+- Stop related coder/reviewer Pods.
+- Remove only child implementation worktree/branch for this Ticket.
