# HyperTwist Phase 4 runtime-library generated-mode selector option owned-execution delivery-mode roster/allowed-mode retention, real-scramble/virtual-cube/smart-cube capability retention, and timing-policy retention preview 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-mode, capability, and timing-policy preview contracts above the already-landed owned-execution scope and runtime-surface retention surfaces.

## Why this packet exists

The prior runtime-library packet let world-context callers explain owned-execution scope, source attribution, deck-title / selection-policy posture, and runtime-surface retention posture for one selector option.

But callers still had to inspect raw launch-policy and retained-capability details if they needed to explain:

- which delivery modes remain allowed and how the retained delivery-mode roster behaves on execute
- whether real-scramble, virtual-cube, and smart-cube capabilities remain available
- what timing-policy posture survives into the owned-execution target

That kept the runtime-library world-context seam behind the already-landed panel-widget and session-actor owned-execution retention-preview lane.

## What changed

- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionDeliveryModeRosterAllowedModeRetentionPreviewSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionRealScrambleVirtualCubeSmartCubeCapabilityRetentionPreviewSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionTimingPolicyRetentionPreviewSurface()`
- 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 delivery-mode roster / allowed-mode retention preview for one selector option
- the truthful owned-execution real-scramble / virtual-cube / smart-cube capability retention preview for one selector option
- the truthful owned-execution timing-policy retention preview for one selector option

without reading raw launch-policy, retained-capability, or modality-availability 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 detail retention, split-phase phase-id/label-fallback provenance, and split-phase duplicate-pruning/survivor provenance preview group, because those are the next truthful owned-execution retained split-phase contracts above the newly-landed delivery-mode, capability, and timing-policy retention preview surfaces.
