# HyperTwist Phase 4 runtime-library generated-mode launch/execution and selector/application context 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 display contracts above the already-landed active coach readiness/eligibility and verification/recognition/review-policy context surfaces.

## Why this packet exists

The prior runtime-library packet let world-context callers explain what is actionable now, what is blocked, and what repository-verification, recognition-provider, and review-policy context applies.

But callers still had to inspect raw generated-mode request/execution panel fields, imported selector-choice state, runtime-surface identity, and launch-config posture if they needed to explain:

- the latest generated-mode request and execution posture
- whether execution is staged, blocked, or ready
- how much selector coverage is already cached
- whether execute will reuse or refresh the stored request

That kept the runtime-library world-context seam behind the already-landed panel-widget and session-actor generated-mode display-contract lane.

## What changed

- added `GetActiveTrainingCoachGeneratedModeLaunchExecutionContextSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorApplicationContextSurface()`
- derived the launch/execution context surface from the active coach panel state plus the already-landed runtime-library readiness/eligibility and verification/recognition/review-policy context surfaces
- derived the selector/application context surface from the active run deck, active imported runtime selection state, active imported generated-mode launch config, and the runtime-library launch/execution context surface
- 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 generated-mode launch request / execution posture
- the truthful selector application coverage / stored-request refresh posture

without reading raw request ids, blocked-reason fields, selector-choice arrays, runtime-surface ids, or launch-config 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 pair inside that lane would be the runtime-library generated-mode selector roster and selector option-menu surfaces, because those are the next truthful selector-display contracts above the newly-landed selector/application context surface.
