Module coordination 

Gradient coordination protocol for distributed backward passes.

This module provides content-addressed Arrow IPC gradient storage and a BackwardPassCoordinator that tracks multi-peer gradient contributions for federated backward pass rounds.

Structs

BackwardPassCoordinator

Coordinates gradient collection and aggregation across peers.

BackwardPassId

Identifies a backward pass round across distributed nodes.

GradientArrowBlock

A gradient stored as an Arrow IPC block with content-addressing.

GradientContribution

A gradient contribution from one participant peer.

Enums

ArrowBlockError

CoordinationError

CoordinationStatus

Status of a coordinated backward pass.
