Module diff 

Structured diff engine — schema-aware, typed diffs between state trees.

Unlike git’s line-based text diffs, AgentStateGraph diffs operate on typed structured data. Each DiffOp describes a specific change (SetValue, AddKey, RemoveKey, etc.) at an exact path in the state tree.

Enums

DiffOp

A single structured change operation within a diff.

DiffValue

A JSON-serializable representation of a value in a diff. We can’t use Object directly because it contains ObjectIds which aren’t meaningful to external consumers.

Traits

ObjectResolver

Trait for resolving ObjectIds to Objects during diff computation. This decouples the diff algorithm from the storage backend.

Functions

diff

Compute a structured diff between two state trees.
