# HyperTwist Phase 4 runtime-library generated-mode selector option owned-execution case, prompt, and delivery 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 preview contracts above the already-landed selector option launch-request metadata and envelope preview surfaces.

## Why this packet exists

The prior runtime-library packet let world-context callers explain imported origin-path / notes provenance and stored request envelope / request-source / persistence posture for one selector option payload.

But callers still had to inspect raw case lookup, seed-case, and launch-preview-derived execution details if they needed to explain:

- which owned case id and canonical state ref would actually be targeted
- what prompt label and prompt kind would be presented on execute
- what delivery mode, reveal posture, and time-target posture would apply

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

## What changed

- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionCasePreviewSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionPromptPreviewSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionDeliveryPreviewSurface()`
- derived the owned-execution case preview surface from the active run state, selected `SelectorId`, and the already-landed runtime-library selector option-menu and launch-request envelope preview surfaces
- derived the owned-execution prompt and delivery preview surfaces from that same active run state and `SelectorId` over the 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-case identity / canonical-state preview for one selector option
- the truthful owned-execution prompt-label / prompt-kind preview for one selector option
- the truthful owned-execution delivery-mode / reveal-posture / time-target preview for one selector option

without reading raw case lookup, seed-case, or launch-request preview 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 puzzle/subset/difficulty, provenance, deck-title/selection-policy, and deck-id/runtime-surface retention preview group, because those are the next truthful owned-execution preview contracts above the newly-landed case, prompt, and delivery preview surfaces.
