What issue are you seeing?

The live console "preview" and /ps both truncate long command names, and I have to resort to ps aux grepping to find what the agent is actually running. At the very least I don't think /ps should truncate because the user has explicitly requested the running process list.

What steps can reproduce the bug?

Have the agent execute a command which is very long, too wide to fit on a single line in your terminal window.

What is the expected behavior?

Repro

• Reproduced this on current main.
• /ps was truncating the first command line to 80 graphemes before width-based wrapping, so long running commands were cut off even when the viewport could show them across wrapped lines.

Root Cause

• The hard 80-grapheme cap existed in both tui/src/history_cell.rs and tui_app_server/src/history_cell.rs.
• I prepared a small local patch that removes that cap for the process-name line, wraps the full first line under the existing bullet prefix, keeps the [...] suffix only when the original command is multiline, and leaves recent_chunks truncation unchanged. The change is mirrored in both implementations and the long-command snapshots now show the full wrapped command path.

Validation

• CARGO_TARGET_DIR=/tmp/codex-target-10072-tui cargo test -p codex-tui ps_output_long_command_snapshot
• CARGO_TARGET_DIR=/tmp/codex-target-10072-app cargo test -p codex-tui-app-server ps_output_long_command_snapshot
• just fix -p codex-tui
• just fix -p codex-tui-app-server
• CARGO_TARGET_DIR=/tmp/codex-target-10072-tui cargo test -p codex-tui
• CARGO_TARGET_DIR=/tmp/codex-target-10072-app cargo test -p codex-tui-app-server

Risk

• Low. This keeps the existing width-based wrapping logic and only removes the extra early truncation on the process-name line.
