}

Immutable coordinator evidence for one execution-local HPO campaign.

This is deliberately passed beside the tuner NodeTask rather than stored in the controller registry or serialized through a generic controller invocation. A tuner session may retain thread-affine native state, but this context contains only portable coordinator facts.

Fields

operation_id: String

Stable identity of this scheduler-owned campaign operation. This is deliberately not a graph node: HPO controls variants of a predictor, it is not part of the predictor topology.

controller_id: ControllerId

Registered controller which owns the invocation-local native session.

target_node_id: NodeId

The model node evaluated for every proposal.

base_variant: VariantPlan

The unexpanded variant from which the tuner proposes candidates.

trial_budget_total: u32

Total native study budget across the initial run and every resumed scheduler call. This is never a per-call proposal count.

study: MethodsHpoStudyConfig

Typed native-study configuration owned by the registered tuner controller. The scheduler never constructs or restores this study.

parameter_paths: BTreeMap<String, String>

Native search-space output name -> direct target-model parameter key. The controller converts each proposal through this explicit mapping; the scheduler only receives the resulting normal VariantPlan.

resume_checkpoint: Option<N4moptCheckpointArtifact>

Optional opaque native state from a prior compatible campaign. It is consumed only by the controller-local session factory and is never sent to scheduler workers.

resume_variants: BTreeMap<i64, VariantId>

Completed scheduler proposals restored with the opaque optimizer. They give a native best() result its stable variant identity on resume.

resume_terminal_trials: Vec<RuntimeHpoTerminalSnapshot>

Full controller-attested native terminal ledger from the package being restored. The session compares this before it may ask another trial.

selection: RuntimeHpoSelectionTarget

The OOF report produced by the scheduler which is fed back to the session after each candidate evaluation.

provenance: RuntimeHpoProvenance

Immutable fingerprints which bind this campaign to the already attested plan, data identities, fold set and influence manifest.
