# HyperTwist Phase 4 runtime-library generated-mode selector option owned-execution split-phase normalization summary and raw-row/normalized-phase fusion 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 retained split-phase normalization and fusion preview contracts above the already-landed split-phase detail-retention and provenance preview surfaces.

## Why this packet exists

The prior runtime-library packet let world-context callers explain retained split-phase coverage, label-fallback provenance posture, and duplicate-pruning survivor posture for one selector option.

But callers still had to inspect raw split-phase rows and downstream fusion derivation details if they needed to explain:

- how retained split-phase rows normalize into the owned-execution phase set
- how raw retained rows map into the resulting normalized phases
- what normalization/fusion posture applies before current-selection inspect surfaces

That kept the runtime-library world-context seam behind the already-landed panel-widget and session-actor split-phase normalization/fusion preview lane.

## What changed

- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionSplitPhaseNormalizationSummaryPreviewSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionSplitPhaseRawRowNormalizedPhaseFusionPreviewSurface()`
- derived both surfaces from the active run state, selected `SelectorId`, and the already-landed 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

- `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-execution split-phase normalization summary preview for one selector option
- the truthful owned-execution split-phase raw-row / normalized-phase fusion preview for one selector option

without reading raw split-phase rows or downstream fusion 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 split-phase current-selection canonical inspect and current-selection survivor-phase-roster inspect pair, because those are the next truthful inspect contracts above the newly-landed normalization-summary and fusion preview surfaces.
