Struct PersistCtx 

pub struct PersistCtx {
    pub items: Vec<PersistItemCtx>,
    pub origins: Vec<Value>,
    pub context: Value,
    pub state: Map<String, Value>,
    pub transaction: Option<u64>,
}

W3 / W4 / W5 (physical-persist-level) context — fires AFTER derivation, on the REAL composed batch. before (W3) may mutate Self::items, may error to abort; after (W4) observes the executor results; onError (W5) may recover.

In a transaction the persist hooks fire ONCE for the whole atomic batch; for a single-op write items is a one-element list. Each item is a composed transact-item-shaped mutation whose expression fields a W3 hook may edit.

Fields

items: Vec<PersistItemCtx>

The composed physical write items (Put/Update/Delete/ConditionCheck).

origins: Vec<Value>

The {model, kind} origin of each logical write feeding the batch.

context: Value

The per-call context.

state: Map<String, Value>

Per-persist scratch.

transaction: Option<u64>

The transaction identity, when this persist is an atomic batch.
