Analysis

The crash is in sc7, which renders rejected/previous edit diffs when replaying conversation history. It calls _.startsWith() where _ is filePath, but filePath is undefined. The function at line 3109 processes structured patches and assumes filePath is always a string.

Reproduction

1. Have a conversation that includes file edit tool uses (possibly rejected edits)
2. Exit the conversation
3. Run claude --resume

Environment
