ClusterEvalContext: The identity of a single live cluster, used to evaluate cluster-coherent scoped parameters in SystemParameterFrontend::pull_cluster_overrides.
ClusterScopeContext: Identity of a cluster, used to build a cluster context kind for cluster-coherent scoped feature flags.

ReplicaEvalContext: The identity of a single live replica, used to evaluate replica-local scoped parameters in SystemParameterFrontend::pull_replica_overrides.
ReplicaScopeContext: Identity of a replica, used to build a replica context kind for replica-local scoped feature flags.
ScopedParameters: Scoped (per-cluster and per-replica) system-parameter overrides, keyed by object id. Each value is the raw (unparsed) string for a parameter whose scoped value differs from the environment-wide value; an absent entry means no override. Empty maps mean no scoped overrides at all.
ScopedParametersScope: The set of objects a ScopedParameters update was evaluated for, used to bound which durable override rows the update may prune.
SynchronizedParameters: A struct that defines the system parameters that should be synchronized
SystemParameterBackend: A backend client for pushing and pulling SynchronizedParameters.
SystemParameterFrontend: A frontend client for pulling SynchronizedParameters from LaunchDarkly.
SystemParameterSyncConfig: A factory for SystemParameterFrontend instances.

system_parameter_sync: Run a loop that periodically pulls system parameters defined in the LaunchDarkly-backed SystemParameterFrontend and pushes modified values to the ALTER SYSTEM-backed SystemParameterBackend.
