# HyperTwist Phase 4 runtime-library generated-mode selector option owned-execution split-phase current-selection label-provenance partition core inspect surface packet

- bounded Phase `4` runtime-consumer slice
- date: `2026-05-09`

## Intent

Stay on the deliberate `UHyperTwistTrainingRuntimeLibrary` world-context consumer lane and expose the next truthful owned-execution retained split-phase current-selection label-provenance partition inspect contracts above the already-landed current-selection dropped-row audit, phase-id fallback roster, and explicit-label roster inspect surfaces.

## Why this packet exists

The prior runtime-library packet let world-context callers inspect:

- which retained rows were dropped during the current-selection audit
- which surviving phases still rely on phase-id fallback labels
- which surviving phases retain explicit labels directly

But callers still had to inspect raw split-phase rows and downstream inspect derivation details if they needed to explain:

- how the surviving retained phases partition by label provenance
- how fallback and explicit-label rosters pair against each other
- what the merged retained ordered provenance roster actually contains

That kept the runtime-library world-context seam behind the already-landed panel-widget and session-actor label-provenance partition inspect lane.

## What changed

- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionSplitPhaseCurrentSelectionLabelProvenancePartitionSummaryInspectSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionSplitPhaseCurrentSelectionLabelProvenancePartitionRosterPairInspectSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionSplitPhaseCurrentSelectionLabelProvenancePartitionMergedOrderedRosterInspectSurface()`
- derived all three surfaces from the active run state, selected `SelectorId`, and the already-landed runtime-library selector option-menu and launch-request preview surfaces
- kept the runtime-library lane purely compositional over already-cached coach/generated-mode state without reopening backend derivation

## Files

- `C:\HyperTwist\UnrealHyperTwist\Source\UnrealHyperTwist\Public\HyperTwistTraining\HyperTwistTrainingRuntimeLibrary.h`
- `C:\HyperTwist\UnrealHyperTwist\Source\UnrealHyperTwist\Private\HyperTwistTraining\HyperTwistTrainingRuntimeLibrary.cpp`
- `C:\HyperTwist\docs\HYPERTWIST_ROADMAP_OVERHAUL_EXPANSION_GUIDE.md`

## Outcome

World-context gameplay and Blueprint callers can now ask the runtime library for:

- the truthful owned-execution split-phase current-selection label-provenance partition summary inspect surface for one selector option
- the truthful owned-execution split-phase current-selection label-provenance partition roster-pair inspect surface for one selector option
- the truthful owned-execution split-phase current-selection label-provenance partition merged ordered roster inspect surface for one selector option

without reading raw split-phase rows or downstream inspect derivation details directly.

## Validation

- full `Development Editor | Win64` MSBuild on `UnrealHyperTwist.sln`

## Next clean slice

Stay on this runtime-library consumer lane only if a real world-context caller still needs one more thin derived coach/generated-mode display contract or displayed-action convenience helper over already-cached state. The next aligned move inside that lane would be the runtime-library generated-mode selector option owned-execution split-phase current-selection merged ordered roster phase-id lookup, normalized-order lookup, and evaluation-order lookup inspect trio, because those are the next truthful inspect contracts above the newly-landed label-provenance partition summary, roster-pair, and merged ordered roster inspect surfaces.
