# HyperTwist Phase 6R-S classic-cube correction resolution closure implementation packet

Created on `2026-05-24`

## Status

- first-party HyperTwist packet
- bounded permissive `Phase 6R-S` implementation slice

## Purpose

This packet lands the current retained shared classic-cube
correction-resolution closure family:

- first-party accepted-resolution ledger state, manual-review acceptance
  routing, and solve-guidance reopen/unlock semantics above the already landed
  `qbr` webcam shell, `rubix-cube-solver` reconstruction/browser-shell/solve
  explanation seams, and the first-party `Phase 6R-R` correction shell

It is not:

- a full `qbr` row transplant
- a full `rubix-cube-solver` row transplant
- a bundled `twistysim.min.js` redistribution packet
- a bundled `arial-unicode-ms.ttf` redistribution packet
- a multilingual `qbr` shell packet
- a generalized solver backend packet
- a broad playback-runtime packet

## Current authority basis

This implementation packet stands on:

- `docs/REPO_LICENSE_TRACKING.md`
- `docs/ops/HYPERTWIST_CROSS_LANE_AUTHORITY_HIERARCHY_AND_RECONCILIATION_2026-05-20.md`
- `docs/arch/HYPERTWIST_PHASE6R_S_CLASSIC_CUBE_CORRECTION_RESOLUTION_CLOSURE_PREPARATION_PACKET_2026-05-24.md`

The retained owner split stays explicit:

- `vivaansinghvi07/rubix-cube-solver`
  - retained primary owner for correction/explanation semantics,
    correction-resolution closure, and solve-guidance reopen/unlock behavior
- `kkoomen/qbr`
  - retained adjunct owner for capture-state continuity, target-face re-scan
    anchoring, and revision-aware reopen posture

The top-level product shell owner does not change here:

- first-party HyperTwist remains the broader recognition-session and
  product-shell owner

## Landed scope

The current code now owns a bounded first-party correction-resolution closure
slice through:

- first-party `HyperTwistRecognition` contract types for:
  - correction-resolution record shape
  - correction-state resolution ledger and last-resolution readout
  - commit-request manual-review action metadata
  - commit-result applied-resolution payloads
- first-party recognition session-state normalization for:
  - resolved correction count
  - last correction resolution
  - correction-resolution ledger persistence across the active session
- active subsystem normalization in:
  - local correction-resolution commit handling above the landed qbr classic
    route
  - correction-target validation before review acceptance
  - resolution upsert behavior keyed by face id plus observation/revision
    identity
  - solve-guidance unlock after full closure
  - correction reopen after a later recommit changes the reviewed face state
- sample contract routing in:
  - `UHyperTwistContractLibrary`
- focused automation coverage in:
  - `HyperTwistClassicCubePhase6RSCorrectionResolutionContractTest.cpp`

## Why this is still intentionally bounded

This packet lands the next bounded correction-resolution closure slice, but it
does not widen into neighboring families or broader ownership.

Still excluded:

- bundled `twistysim.min.js` redistribution
- bundled `arial-unicode-ms.ttf` redistribution
- standalone multilingual `qbr` shell ownership
- generalized solver backend ownership
- broad playback-runtime ownership
- donor-shaped frontend transplant

## Validation

Build validation:

- `C:\Program Files\Epic Games\UE_5.7\Engine\Build\BatchFiles\Build.bat UnrealHyperTwistEditor Win64 Development -Project='C:\HyperTwist\UnrealHyperTwist\UnrealHyperTwist.uproject' -WaitMutex -NoHotReloadFromIDE -NoUba`

Focused automation validation:

Regression automation validation:

- `HyperTwist.Permissive.ClassicCube.Phase6R.R`
- `HyperTwist.Permissive.RubixCubeSolver.Phase6R.Q`
- `HyperTwist.Permissive.RubixCubeSolver.Phase6R.P`
- `HyperTwist.Permissive.Qbr.Phase6R.O`
- `HyperTwist.Permissive.RubixCubeSolver.Phase6R.C`
- `HyperTwist.CleanRoom.CubeDesk`

Expected covered tests:

- `CorrectionResolutionUnlock`
- `CorrectionResolutionPartialClosure`
- `CorrectionResolutionReopen`
- existing `Phase 6R-R`, `rubix-cube-solver`, `qbr`, and `CubeDesk`
  regression suites

## Queue effect

This packet consumes the current bounded `Phase 6R-S` implementation slice.

`kkoomen/qbr` remains partially incorporated:

- landed now:
  - classic-cube recognition calibration contract
  - ordered face-observation contract
  - classic-cube webcam shell
  - shared correction-target capture-state and re-scan adjunct
- still deferred:
  - bundled-font redistribution and multilingual solve shell

`vivaansinghvi07/rubix-cube-solver` remains partially incorporated:

- landed now:
  - committed-face reconstruction session
  - face-vote replacement ledger
  - final classic-net shaping above aggregated committed faces
  - browser/webcam shell profile and browser-shell session-state composition
  - bounded solve explanation/recommendation stage ladder and recommendation
    state
  - bounded correction profile, contradiction-aware correction state, and
    correction-explanation shell routing
  - correction-resolution ledger, manual-review acceptance, and
    solve-guidance reopen/unlock semantics
- still deferred:
  - bundled `twistysim.min.js` redistribution
  - generalized solver backend ownership
  - broad playback-runtime ownership

The next clean move is:

- a source-backed `Phase 6R-T` `roice3/MagicTile` transform-aware macro
  remapping preparation/control pass

Keep the future sequencing guards visible:

- `vivaansinghvi07/rubix-cube-solver`
  - do not copy or redistribute `frontend/lib/twistysim.min.js` without
    preserving or replacing its upstream provenance/license in any future
    widening that would ship that asset
- `kkoomen/qbr`
  - do not copy or redistribute `src/assets/arial-unicode-ms.ttf` without
    separate confirmation or replacement in any future widening that would
    ship that asset
- `roice3/MagicTile`
  - keep the next widening bounded to transform-aware macro remapping rather
    than broad non-Euclidean interaction or host-shell ownership
- first-party HyperTwist
  - keep the shared classic-cube correction shell closed by default unless a
    narrower first-party gap is proven above the landed resolution-closure
    seam
