Struct Delta 

pub struct Delta {
    pub changed: HashMap<String, ValueWord>,
    pub removed: Vec<String>,
}

A delta between two values, keyed by content path.

Paths use dot-separated notation:

• "field_name" for top-level fields of a TypedObject
• "field_name.nested" for nested fields
• "[0]", "[1]" for array indices
• "frames.[0].locals.[2]" for deeply nested paths

Fields

changed: HashMap<String, ValueWord>

Fields/paths that changed, mapped to their new values.

removed: Vec<String>

Paths that were removed (present in old, absent in new).

pub fn is_empty(&self) -> bool

True if this delta represents no change.

pub fn change_count(&self) -> usize

Number of changes (additions + modifications + removals).
