# HyperTwist Phase 4 gameplay generated-mode selector option owned execution delivery-mode / reveal-posture / time-target preview surface packet

Created on `2026-05-08`

Status:

- first-party HyperTwist packet
- bounded Phase `4` gameplay-facing consumer slice

## Purpose

This packet closes the next thin gameplay-facing consumer seam above the panel-widget and session-actor generated-mode selector option owned execution prompt-label / prompt-kind preview surface by exposing one parameterized owned execution delivery-mode / reveal-posture / time-target preview surface for a chosen selector id.

The open tasks were:

- stop forcing gameplay / Blueprint callers to rebuild generated deck execution posture rules just to explain how a chosen imported option would actually run
- expose exact direct covered-case delivery posture plus exact generated owned execution delivery mode, reveal posture, and time target whenever the generated-mode payload is previewable
- keep the surface derived from already-cached gameplay consumer run, selector, and launch-request preview state instead of widening into backend logic

It is not:

- a selector-dispatch behavior change
- a generated-mode launch-request persistence behavior change
- a generated-mode execution deck synthesis change
- a broader gameplay UI composition pass

## Scope

Bounded lane:

- add first-party owned execution delivery preview surfaces in shared training types
- add a coach-library helper that projects delivery mode, reveal posture, and time target over the already-landed launch-request preview surface
- expose that parameterized delivery preview surface on `HyperTwistTrainingPanelWidget` and `HyperTwistTrainingSessionActor`
- keep the derivation presentation-only and rooted in the already-owned selector/runtime/request surfaces

Out of scope:

- changing selector-choice apply behavior
- changing stored launch-request creation, refresh, or execute behavior
- changing generated-mode execution deck synthesis
- widening into dashboard-only or broader gameplay composition work

## Why this was the right next packet

Before this slice:

- gameplay-facing panel/session consumers already exposed truthful owned case identity, canonical-state, and prompt presentation preview for imported selector options
- callers could tell which owned case target and prompt presentation would result from a chosen option

But one thin consumer seam was still open:

- callers still had to reconstruct delivery mode, reveal posture, and target-time behavior from direct covered-case launch rules, active session mode, and generated-mode execution deck synthesis rules if they wanted to explain how the resulting owned execution would actually run

That meant:

- target identity and prompt presentation were already thin and reusable
- but concrete execution posture still leaked generated deck composition and direct launch rules into callers

So the next bounded move was:

- keep the already-landed owned execution case and prompt preview surfaces unchanged in behavior
- reuse the already-cached launch-request preview surface to expose one narrow owned execution delivery preview surface above it

## What landed

Primary code changes:

- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingTypes.h`
  - added `FHyperTwistTrainingCoachGeneratedModeSelectorOptionOwnedExecutionDeliveryPreviewEntrySurface`
  - added `FHyperTwistTrainingCoachGeneratedModeSelectorOptionOwnedExecutionDeliveryPreviewSurface`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingCoachLibrary.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingCoachLibrary.cpp`
  - added `DeriveCoachGeneratedModeSelectorOptionOwnedExecutionDeliveryPreviewSurface(...)`
  - delivery preview is derived from cached run state plus the already-landed launch-request preview surface
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingPanelWidget.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingPanelWidget.cpp`
  - added `GetDisplayedCoachGeneratedModeSelectorOptionOwnedExecutionDeliveryPreviewSurface(const FString& SelectorId)`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingSessionActor.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingSessionActor.cpp`
  - added `GetDisplayedCoachGeneratedModeSelectorOptionOwnedExecutionDeliveryPreviewSurface(const FString& SelectorId)`

Surface behavior:

- reports exact direct covered-case delivery posture from the active session mode plus the resolved covered case
- reports exact generated owned execution delivery mode and seed-case time target whenever the chosen option yields a previewable generated-mode payload
- reports truthful reveal posture, including the generated owned-execution rule that reveal is disabled because the synthetic case clears canonical notation
- keeps unresolved or payload-invalid choices inspectable as blocked delivery-preview states instead of collapsing them into a generic unavailable branch
- keeps the surface presentation-only and compatible with the already-landed launch / execution, request-alignment, stored-request delta, launch-request payload / refresh-preview, launch-request metadata / origin-notes preview, launch-request envelope / request-source preview, owned execution case / canonical-state preview, and owned execution prompt preview surfaces

## Validation

Validation target:

- full `Development Editor|Win64` build of `C:\HyperTwist\UnrealHyperTwist\UnrealHyperTwist.sln`

Result:

- passed with `0` warnings and `0` errors

## Follow-on

The next bounded packet on this same gameplay-facing consumer lane should stay thin and expose one generated-mode selector option owned execution puzzle-id / subset-id / difficulty preview surface so callers can render the resulting owned execution scope and difficulty posture for a chosen option without rebuilding generated deck composition rules directly.
