# HyperTwist Phase 4 runtime-library generated-mode selector option owned-execution split-phase detail retention, phase-id/label-fallback provenance, and duplicate-pruning/survivor provenance 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 detail and provenance preview contracts above the already-landed owned-execution delivery-mode, capability, and timing-policy retention surfaces.

## Why this packet exists

The prior runtime-library packet let world-context callers explain retained delivery-mode coverage, modality capability posture, and timing-policy posture for one selector option.

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

- whether retained split-phase detail still survives into owned execute
- how phase id and explicit-label fallback provenance behave across those retained rows
- what duplicate-pruning and survivor posture applies before downstream normalization and inspect surfaces

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

## What changed

- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionSplitPhaseDetailRetentionPreviewSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionSplitPhasePhaseIdLabelFallbackProvenancePreviewSurface()`
- added `GetActiveTrainingCoachGeneratedModeSelectorOptionOwnedExecutionSplitPhaseDuplicatePruningSurvivorProvenancePreviewSurface()`
- derived all three 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

## 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 owned-execution split-phase detail retention preview for one selector option
- the truthful owned-execution split-phase phase-id / label-fallback provenance preview for one selector option
- the truthful owned-execution split-phase duplicate-pruning / survivor provenance preview for one selector option

without reading raw split-phase rows or normalization 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 normalization summary and split-phase raw-row/normalized-phase fusion preview group, because those are the next truthful retained split-phase contracts above the newly-landed detail-retention and provenance preview surfaces.
