# HyperTwist Phase J-DU validation necking-state packets and bounded ongoing-state solidarity implementation packet

## Status

`Phase J-DU` is now landed locally as the one-hundred-twenty-fifth bounded
HyperTwist-native validation and benchmarking slice.

## Landed surfaces

- validation necking-state packet contract
- validation ongoing-state solidarity boundary

## Code

- extended bundle and necking/solidarity contract structs in
  `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingValidationBenchmarkLibrary.h`
- bundled contract data and query functions in
  `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingValidationBenchmarkLibrary.cpp`
- runtime accessors in
  `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingRuntimeLibrary.h`
  and
  `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingRuntimeLibrary.cpp`
- focused automation in
  `UnrealHyperTwist/Source/UnrealHyperTwist/Tests/HyperTwistValidationPhaseJDUNeckingSolidarityContractTest.cpp`

## Boundaries preserved

- keep validation necking-state and ongoing-state solidarity posture first-party and runtime-evidence local
- do not widen into generic necking-state platforms or ongoing solidarity systems
- do not widen into generic dashboards, necking continuity platforms, or release authority
- do not widen into cross-product ongoing solidarity ownership or necking-state orchestration

## Canon result

- `Phase J-A` through `Phase J-DU` are now landed as the first bounded validation
  and benchmarking scaffold in current code
- `Phase J-EK` validation pulpit-state packets and bounded ongoing-state caucus
  is the next deliberate seam if this lane is continued
