 ## Goal
 
-Require two consecutive Ctrl+C keystrokes (within a short timeout) to exit the TUI, preventing accidental termination from a single SIGINT.
+Require two consecutive Ctrl+D keystrokes (within a short timeout) to exit the TUI, preventing accidental termination from a single SIGINT.
 
 ## Acceptance Criteria
 
-- Add a `[tui] require_double_ctrl_c = true` config flag (default `false`) to enable double‑Ctrl+C exit confirmation.
-- When `require_double_ctrl_c` is enabled:
-  - First Ctrl+C within the TUI suspends exit and shows a status message like "Press Ctrl+C again to confirm exit".
-  - If a second Ctrl+C occurs within a configurable timeout (e.g. 2 sec), the TUI exits normally.
-  - If no second Ctrl+C arrives before timeout, clear the confirmation state and resume normal operation.
-- Ensure that child processes (shell tool calls) still receive SIGINT immediately and are not affected by the double‑Ctrl+C logic.
-- Prevent immediate exit on Ctrl+D (EOF); require the same double‑confirmation workflow as for Ctrl+C when EOF is received.
+- Add a `[tui] require_double_ctrl_d = true` config flag (default `false`) to enable double‑Ctrl+D exit confirmation.

+- Prevent immediate exit on Ctrl+D (EOF); require the same double‑confirmation workflow as for Ctrl+D when EOF is received.
 - Provide unit or integration tests simulating SIGINT events to verify behavior.
 
 ## Implementation
 
 **How it was implemented**  
-- Introduce `require_double_ctrl_c: bool` in `ConfigToml` → `Config` under the `tui` section, with default `false`.
+- Introduce `require_double_ctrl_d: bool` in `ConfigToml` → `Config` under the `tui` section, with default `false`.
 - Extend the TUI event loop (e.g. in `tui/src/app.rs`) to handle SIGINT events:
-  1. If `require_double_ctrl_c` is disabled, behave as before (exit on first Ctrl+C).
+  1. If `require_double_ctrl_d` is disabled, behave as before (exit on first Ctrl+D).
   2. If enabled and not already confirming, enter a `ConfirmExit` state, record timestamp, and display confirmation message.
-  3. If enabled and in `ConfirmExit` state, exit immediately on second Ctrl+C.
+  3. If enabled and in `ConfirmExit` state, exit immediately on second Ctrl+D.
   4. On each TUI tick, if in `ConfirmExit` and timeout elapsed, clear `ConfirmExit` state.
-  5. Intercept EOF (Ctrl+D) events in the input handler and apply the same `ConfirmExit` logic as for Ctrl+C when `require_double_ctrl_c` is enabled.
+  5. Intercept EOF (Ctrl+D) events in the input handler and apply the same `ConfirmExit` logic as for Ctrl+D when `require_double_ctrl_d` is enabled.
 - Add rendering logic in the status bar (`tui/src/status_indicator_widget.rs` or similar) to show the confirmation prompt.
 
 **How it works**  
-- On startup, the TUI reads `require_double_ctrl_c` from config.
-- When SIGINT is captured by the event loop, double‑Ctrl+C logic intercepts and requires confirmation.
+- On startup, the TUI reads `require_double_ctrl_d` from config.
+- When SIGINT is captured by the event loop, double‑Ctrl+D logic intercepts and requires confirmation.
 - Child processes continue to get raw SIGINT from the OS because the TUI should delegate signals while awaiting child termination.
 
 ## Notes
 
-- Make the double‑Ctrl+C timeout duration configurable if desired (e.g. via `tui.double_ctrl_c_timeout_secs`).
-- Ensure that existing tests for Ctrl+C behavior are updated or new tests added to cover the confirmation state.
+- Make the double‑Ctrl+D timeout duration configurable if desired (e.g. via `tui.double_ctrl_d_timeout_secs`).
+- Ensure that existing tests for Ctrl+D behavior are updated or new tests added to cover the confirmation state.
