context: Vec<String>

Context breadcrumbs (e.g., [“File: main.rs”, “Class: Server”, “Function: handle_request”])

path: String

File path this chunk belongs to

signature: Option<String>

Function/method signature (if applicable) Example: “fn sort<T: Ord>(items: Vec) -> Vec”

docstring: Option<String>

Extracted docstring/documentation comment

is_complete: bool

Whether this chunk is complete (not split)
