# HyperTwist Phase J-FX validation zucchetto-state ledgers and bounded ongoing-state biretta implementation packet

Date: 2026-06-04

`Phase J-FX` is now landed locally as the one-hundred-eightieth bounded
first-party validation seam.

## Landed scope

- validation zucchetto-state ledger contract
- validation ongoing-state biretta boundary
- bundled runtime accessors for both surfaces
- focused automation coverage for contract and boundary resolution
- package reference continuity now includes the immediately previous
  pectoral-cross/ring package plus the new zucchetto/biretta package

## Notes

- the `zucchetto-state` / `ongoing-state biretta` naming is an explicit local
  continuation inference from the prior landed sequence and current roadmap
  milestone naming
- this remains a bounded first-party runtime-evidence lane and does not widen
  into generic platforms, cross-product telemetry authority, or release gates

## Code surfaces

- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingValidationBenchmarkLibrary.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingValidationBenchmarkLibrary.cpp`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Public/HyperTwistTraining/HyperTwistTrainingRuntimeLibrary.h`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingRuntimeLibrary.cpp`
- `UnrealHyperTwist/Source/UnrealHyperTwist/Tests/HyperTwistValidationPhaseJFXZucchettoBirettaContractTest.cpp`

## Guardrails reaffirmed

- keep validation zucchetto-state and ongoing-state biretta posture
  first-party and runtime-evidence local
- do not widen into generic zucchetto-state platforms or ongoing biretta
  systems
- do not widen into cross-product ongoing biretta ownership or zucchetto
  orchestration
- do not turn the seam into release-gate authority or public leaderboard logic

## Next seam

- `Phase J-GQ`
