Analysis

The crash occurs in bG8, which processes web search results (searchCount, totalResultCount). It appears to be iterating over a result set where an entry is undefined/null, likely from a WebSearch tool result in the session being forked.

The function $VB (which renders the tool result message for web search) calls bG8(T.results) without null-checking T or T.results.

Steps to Reproduce

1. Have a session that used web search
2. Run /fork
3. Observe crash

Expected Behavior

/fork should successfully fork the session, handling any null/undefined tool results gracefully.

Environment

• Platform: macOS (Darwin 25.2.0)
