+Merged and completed the workspace Panel close-done-Tickets action.
+
+Summary:
+- Panel `Close` action now closes safe already-done open Tickets through `LocalTicketBackend::close(...)`.
+- Safe-close guard requires local status open, `workflow_state: done`, no non-empty `attention_required`, no non-empty `action_required`, and no existing `resolution.md`.
+- Unsafe close attempts return bounded diagnostics before mutation.
+- Generated resolution text is deterministic/non-LLM and states that the Ticket was already done and the close action did not start implementation, workflow-state changes, Orchestrator/Companion launch, or worker invocation.
+- Panel refresh is scheduled after the action path so closed rows leave the open list.
+
+Merged branch/worktree:
+- Branch: `panel-close-done-tickets`
+- Commit: `6d41ed3 tui: close done tickets from panel`
+- Merge commit on `develop`: `2415956 merge: close done tickets from panel`
+
+Validation passed after merge:
+- `cargo test -p tui multi_pod --lib`
+- `cargo test -p tui workspace_panel --lib`
+- `cargo check -q`
+- `cargo fmt --check`
+- `git diff --check`
+- `cargo run -q -p yoi -- ticket doctor`
+- `nix build .#yoi`
+
+Cleanup completed:
+- Stopped coder/reviewer Pods and reclaimed scope.
+- Removed `.worktree/panel-close-done-tickets`.
+- Deleted branch `panel-close-done-tickets`.
+
+Residual note:
+- Non-open local status blocker has an explicit implementation guard but no dedicated focused test; reviewer accepted this as non-blocking because success and other unsafe cases are covered.

+## Review: approve
+
+Final merge-completion approval after merge to `develop` and post-merge validation.
+
+Evidence:
+- Merged branch `panel-close-done-tickets` with `--no-ff`.
+- Reviewer `reviewer-panel-close-done` approved the branch-local implementation.
+- Post-merge validation passed: `cargo test -p tui multi_pod --lib`, `cargo test -p tui workspace_panel --lib`, `cargo check -q`, `cargo fmt --check`, `git diff --check`, `cargo run -q -p yoi -- ticket doctor`, and `nix build .#yoi`.
+- Coder/reviewer Pods stopped and delegated scope reclaimed.
+- Merged worktree removed and branch deleted.
+
+This approval is for the merged main-branch result, not merely the branch-local reviewer verdict.
