Struct LayoutClientSlices 

pub struct LayoutClientSlices {
    pub leaforder: Option<Value>,
    pub focused_node_id: String,
    pub magnified_node_id: String,
    pub pending_backend_actions: Option<Value>,
}

SPEC_864 Phase 2 — the frontend-owned LayoutState slices carried by a full-row-replace push (the UpdateObject→LayoutSetTree route). The reducer applies focused_node_id/magnified_node_id to its TabRecord; leaforder and pending_backend_actions are opaque pass-through JSON the persist subscriber writes verbatim (no algebra re-run in the subscriber — that would be a new divergence surface).

Semantics are REPLACE, mirroring the legacy update_raw whole-row write this route retires: an absent/null leaforder or pending_backend_actions CLEARS the persisted column (pushing the row without processed actions is how the frontend acks its backend-action queue); an empty focused_node_id/magnified_node_id clears focus/ magnify. A LayoutSetTree with slices: None (granular/tree-only callers) leaves all four columns untouched.

Fields

leaforder: Option<Value>

Frontend-recomputed geometry cache (getLeafOrder). Not read on reproject; persisted only for legacy readers. None = clear.

focused_node_id: String

Focused layout-node id; empty = clear.

magnified_node_id: String

Magnified layout-node id; empty = clear.

pending_backend_actions: Option<Value>

The backend→frontend action queue as the client sees it after processing. None = clear (the ack path).
