# HyperTwist Phase 4 runtime-library generated-mode selector option execution-impact and request-alignment 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 execution-preview contracts above the already-landed selector option dispatch surface.

## Why this packet exists

The prior runtime-library packet let world-context callers explain owned-case coverage, selection-only choices, and whether a selector option dispatches through direct owned-case launch or generated-choice application.

But callers still had to inspect raw launch-config rebuilds, request-match checks, and unresolved-selector derivation if they needed to explain:

- whether an option starts a direct owned case immediately
- whether applying an option would reuse the stored request, require refresh, or stay blocked
- whether the current selection leaves execute unchanged
- how the resulting selector state aligns with the stored generated-mode request

That kept the runtime-library world-context seam behind the already-landed panel-widget and session-actor selector option execution-impact and request-alignment display-contract lane.

## What changed

- added `GetActiveTrainingCoachGeneratedModeSelectorOptionExecutionImpactSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionRequestAlignmentSurface()`
- derived the execution-impact surface from the active run state, selected `SelectorId`, and the already-landed runtime-library launch/execution context, selector option-menu, and selector option dispatch surfaces
- derived the request-alignment surface from that same active run state and `SelectorId` over the runtime-library selector option-menu, dispatch, and execution-impact 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\docs\HYPERTWIST_ROADMAP_OVERHAUL_EXPANSION_GUIDE.md`

## Outcome

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

- the truthful per-option execute-impact posture
- the truthful per-option stored-request alignment preview

without reading raw launch-config rebuilds, request-match checks, or unresolved-selector 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 pair inside that lane would be the runtime-library generated-mode selector option stored-request delta and hypothetical launch-request payload / refresh-preview surfaces, because those are the next truthful selector-request-delta contracts above the newly-landed request-alignment surface.
