 - Automated examples or tests verify the new rendering behavior.
 
 ## Implementation
+This change will touch both the event-processing and rendering layers of the Rust TUI:
 
-**How it was implemented**  
-- Update the internal shell-command renderer to strip out `bash -lc` wrappers and emit raw commands.
-- Modify the message formatting component to place role labels and content on one line.
-- Refactor the result-annotation logic to emit `✅ 12ms` or `exit code: 123 12ms`.
-- Add or extend tests/examples to cover these formatting rules.
+- **Event processing** (`codex-rs/exec/src/event_processor.rs`):
+  - Strip any `bash -lc` wrapper when formatting shell commands via `escape_command`.
+  - Replace verbose `BackgroundEvent` logs for sandbox-denied errors and automatic retries with a unified exec-command begin/end sequence.
+  - Annotate completed commands with either a checkmark (✅) and `<duration>ms` for success or `exit code: N <duration>ms` for failures.
+
+- **TUI rendering** (`codex-rs/tui/src/history_cell.rs`):
+  - Collapse consecutive `BackgroundEvent` entries related to exec failures/retries into the standard active/completed exec-command cells.
+  - Update `new_active_exec_command` and `new_completed_exec_command` to use the new inline format (icon or exit code + duration, with `$ <command>` on the same block).
+  - Ensure role labels and plain-text messages render on a single line separated by a space.
+
+- **Tests** (`codex-rs/tui/tests/`):
+  - Add or update test fixtures to verify:
+    - Commands appear without any `bash -lc` boilerplate.
+    - Completed commands show the correct checkmark or exit-code annotation with accurate duration formatting.
+    - Background debugging events no longer leak raw debug strings and are correctly collapsed into the exec-command flow.
