+## Implementation report
+
+Implementation routing started after the previously deferred TUI table-rendering work was merged and cleaned up.
+
+Worktree/branch:
+- Worktree: `.worktree/tui-composer-history-persistence`
+- Branch: `tui-composer-history-persistence`
+- Base/routing commit: `ff5f985 ticket: route composer history persistence`
+
+Spawned sibling Coder Pod:
+- `coder-tui-composer-history-persistence`
+- Scope: non-recursive read on parent workspace root plus recursive write limited to the child worktree.
+
+Routing context:
+- The earlier `defer_parallel_tui_work` decision is resolved because `tui-chat-markdown-table-rendering` has been merged, closed, and cleaned up.
+- This Ticket is now the active TUI implementation work.
