Summary

Vertical tabs can briefly show an In progress agent status indicator for shell startup commands that Warp runs during session bootstrap, even though those commands were not user-initiated work inside the agent conversation.

Problem

Vertical tabs intentionally show an In progress indicator for user-initiated shell commands within agent conversations. The adjacent startup path appears to leak into the same status surface: while a shell is starting up, a default shell startup/bootstrap command can make the agent conversation row look active for a short time.

There is already related protection for pane title/command-name updates during startup: after bootstrapping, the next shell title event is ignored so it does not overwrite the agent conversation title. The status indicator appears to be computed through a separate path and can still reflect startup-command long-running state.

Expected behavior

Agent conversation rows in vertical tabs should not show an In progress indicator for shell startup/bootstrap commands. The indicator should remain reserved for actual agent work or user-initiated shell commands inside the agent conversation.

Actual behavior

The vertical-tab agent status badge can briefly show In progress during shell startup when a startup/bootstrap command runs long enough to be treated as an active long-running command.

Reproduction steps or desired workflow

1. Open an agent conversation in a tab with vertical tabs enabled.
2. Trigger a shell startup/bootstrap path for that conversation pane, such as opening/restoring a session where Warp runs default shell startup commands.
3. Observe the vertical-tabs row while the shell startup command runs.
4. The row can briefly show the In progress indicator even though no user-initiated agent shell command is running.

• app/src/terminal/view.rs (handle_session_bootstrapped, ModelEvent::Title): the pane title path updates pane configuration after bootstrap and suppresses the next title event from causing another pane-configuration update.
• app/src/terminal/view/pane_impl.rs (selected_conversation_status, selected_conversation_status_for_display): agent chrome/status can derive InProgress from the terminal being long-running.
