Module training_runtime 

Native training orchestration outcome and common runtime entry point.

The portable contracts in this module use Typed Canonical Value v1 (TCV1). Historical graph, plan, controller, parameter, and bundle fingerprints keep their pre-existing algorithms.

Structs

BoundTrainingOutput

One resolved output binding and the actual portable blocks it selected.

PortableFullRefitExecution

Native artifacts and execution evidence produced by the first, scheduler only step of a V3 full refit. The V3 outcome/package writer consumes this result to create a new durable child; it must not mutate the parent.

PortableFullRefitExecutionInput

Target-bound input for the scheduler-owned full-refit half of Package V3. This is deliberately not a replay request: it accepts a new training cohort attestation and never touches a source execution bundle, source scores, source predictions, or source artifacts.

PortableRefitExecutionBundleV3

Refit-only child execution bundle for Package V3.

PortableRefitOutcomeV3

A new V3 training outcome produced by a target-bound full refit.

PortableRefitPackageV3

Closed Package V3 child created by a successful full refit.

PortableRefitPackageV3BuildInput

Input for the DAG-ML-owned V3 child writer. The caller supplies only fresh execution evidence and identifiers; source-package content is used exclusively to revalidate the closed parent recipe and output projection.

TrainingExecutionInput

Host-owned resources and portable identifiers for one native training run.

TrainingOutcome

Portable result of COMPILE/PLAN/FIT_CV/SELECT and optional REFIT.

TrainingRefitOutcome

Exact W0 refit state embedded in TrainingOutcome.

Functions

build_oof_prediction_cache_payloads

build_oof_prediction_cache_records

build_oof_prediction_requirements

Derive portable OOF requirements from the blocks produced by an existing FIT_CV execution. Shared by the training operation and host capture paths.

build_portable_refit_package_v3

Atomically construct the outcome, execution bundle and package child of a successful full refit. No V2 score, selection, prediction cache, conformal state or process-local handle is copied into this V3 family.

derive_portable_full_refit_target_plan

Derive the only execution plan a V3 full REFIT may use for a new cohort.

execute_portable_full_refit

Execute exactly one portable native full refit from a closed recipe.

execute_training

Execute COMPILE/PLAN -> FIT_CV -> SELECT -> optional REFIT and return the complete portable W0 outcome.

validate_portable_refit_target_plan

Validate a persisted V3 target plan against the parent recipe without reusing the parent’s cohort-specific plan fingerprint.
