# HyperTwist Phase J-N validation stable-state ledgers and bounded continuation-state digests implementation packet

## Status

`Phase J-N` is now landed locally as the fourteenth bounded HyperTwist-native
validation and benchmarking slice.

## Landed surfaces

- validation stable-state ledger contract
- validation continuation-state digest boundary

## Code

- extended bundle and stable/digest 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/HyperTwistValidationPhaseJNStableContinuationDigestContractTest.cpp`

## Boundaries preserved

- keep validation stable-state and continuation-state digest posture first-party and runtime-evidence local
- do not widen into generic state-tracking platforms or operations digest systems
- do not widen into long-lived queue ownership, settled-state governance platforms, or release governance authority
- do not widen into generic ongoing-operations dashboards

## Canon result

- `Phase J-A`, `Phase J-B`, `Phase J-C`, `Phase J-D`, `Phase J-E`,
  `Phase J-F`, `Phase J-G`, `Phase J-H`, `Phase J-I`, `Phase J-J`,
  `Phase J-K`, `Phase J-L`, `Phase J-M`, and `Phase J-N` are now landed as
  the first bounded validation and benchmarking scaffold in current code
- `Phase J-AL` validation spiraled-state ledgers and bounded ongoing-state choruses
  is the next deliberate seam if this lane is continued
