Struct TypesContextSnapshot 

pub struct TypesContextSnapshot {
    pub facts: HashMap<TypesContextKey, Vec<FactId>>,
    pub intent_id: Option<IntentId>,
    pub metadata: HashMap<String, String>,
    pub version: u64,
}

Immutable context snapshot.

This represents a point-in-time view of context. The existing context::Context remains for runtime mutation; this is for snapshot/serialization.

Uses “Types” prefix to avoid collision with existing Context.

Fields

facts: HashMap<TypesContextKey, Vec<FactId>>

Facts organized by key.

intent_id: Option<IntentId>

Root intent ID.

metadata: HashMap<String, String>

Metadata.

version: u64

Version number for optimistic concurrency.
