Enum FnEmission 

pub enum FnEmission {
    Data(HandleId),
    Complete,
    Error(HandleId),
}

A single emission within a FnResult::Batch — one element of an actions.down(msgs) call. Processed in sequence within the same wave.

Variants

Data(HandleId)

DATA payload. Processed via commit_emission — sets cache, queues Dirty (if not already dirty per R1.3.1.a) + Data, propagates to children. No equals substitution in Batch context (R1.3.2.d / R1.3.3.c: multi-message waves pass through verbatim).

Complete

COMPLETE terminal. Cascades per R1.3.4 / Lock 2.B.

Error(HandleId)

ERROR terminal with error-value handle. Cascades per R1.3.4; ERROR dominates COMPLETE (Lock 2.B).
