Module strategy 

Running a [TrainingStrategy].

The strategy types are contracts — a strategy is a graph-level attribute, part of what a graph is — so they live in soma-core beside the graph. Running one is not: it shards inputs, calls workers in a round loop, aggregates gradients and redistributes states. That is execution, and execution lives here.

See the “soma-core holds contracts, not execution” entry in the design decisions.

Structs

TransportContext

A StrategyContext over one Transport per worker.

WorkerIdentity

How a worker can be named by a RemoteTarget.

Traits

GradientAggregator

Contract for gradient aggregation across workers.

StateAggregator

Contract for federated state aggregation.

StrategyContext

Context provided to strategy executors. Abstracts worker communication — the strategy doesn’t know about WS/HTTP.

StrategyExecutor

Contract for training strategy execution. Every TrainingStrategy variant implements this — including Local.
