# HyperTwist Phase 4 runtime-library generated-mode selector option launch-request metadata and envelope 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 generated-mode selector launch-request provenance and envelope preview contracts above the already-landed launch-request preview surface.

## Why this packet exists

The prior runtime-library packet let world-context callers explain current-vs-hypothetical-vs-stored selector deltas and preview the resulting generated-mode launch-request payload and refresh posture.

But callers still had to inspect raw runtime-surface metadata and stored launch-request envelope fields if they needed to explain:

- which imported origin paths and notes stay attached to one hypothetical selector option payload
- what stored request id, request time, request source, and persistence posture apply
- how that provenance and envelope posture differs for direct owned-case launch versus payload-backed generated-mode execute

That kept the runtime-library world-context seam behind the already-landed panel-widget and session-actor selector option launch-request metadata and envelope preview display-contract lane.

## What changed

- added `GetActiveTrainingCoachGeneratedModeSelectorOptionLaunchRequestMetadataPreviewSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionLaunchRequestEnvelopePreviewSurface()`
- derived the metadata preview surface from the active run state, selected `SelectorId`, and the already-landed runtime-library selector option-menu and launch-request preview surfaces
- derived the envelope preview surface 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 imported origin-path / notes provenance preview for one selector option payload
- the truthful stored request envelope / request-source / persistence preview for one selector option payload

without reading raw runtime-surface metadata or stored launch-request envelope fields 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 case, prompt, and delivery preview group, because those are the next truthful owned-execution preview contracts above the newly-landed launch-request envelope preview surface.
