# Bug 4: Run Button Does Not Start Agent

## Symptom

Clicking the "Run" button in the AgentPanel does not visibly start an agent. No feedback is shown to the user.

## Root Cause

When multiple agents are configured in `project.toml` (e.g. supervisor, coder-1, coder-2), `handleRunClick` shows a role-selector dropdown instead of starting an agent directly. The dropdown may not be visible due to layout/positioning issues, or the click handler may be swallowed.

## Reproduction Steps

1. Start the server and open the web UI
2. Expand a story in the Agent panel
3. Click the "Run" button
4. Observe: nothing visible happens (no agent starts, no dropdown appears)

## Proposed Fix

Investigate whether the role-selector dropdown is rendering but hidden (z-index, overflow, positioning), or whether the click event is not reaching `handleRunClick`. If the dropdown is the issue, consider starting the default agent directly and offering role selection separately.
