+## Implementation report
+
+Implementation routing started in parallel with the active ToolExecutionContext and TicketList work.
+
+Worktree/branch:
+- Worktree: `.worktree/panel-display-composer-keys`
+- Branch: `panel-display-composer-keys`
+- Base/routing commit: `d95b3ff ticket: route parallel ticketlist and panel work`
+
+Spawned sibling Coder Pod:
+- `coder-panel-display-composer-keys`
+- Scope: non-recursive read on parent workspace root plus recursive write limited to the child worktree.
+
+Parallel-routing rationale:
+- User asked to prefer parallel work when conflicts are absent or expected small.
+- This Ticket is primarily TUI panel/composer UX and is independent from the core ToolExecutionContext migration and TicketList output shaping.
+- Coder was instructed to avoid Ticket backend/tool output changes unless necessary.

+- Any non-mechanical design conflict should be escalated rather than broadened.
