# HyperTwist Phase 6R-AT rubix-cube-solver twistysim asset review boundary implementation packet

Created on `2026-05-31`

## Status

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

## Purpose

This packet lands the narrower first-party review layer above the already
landed `rubix-cube-solver` browser-shell and solve-explanation seams.

The landed slice is:

- first-party bundled browser visualization asset review boundary for the
  retained `twistysim.min.js` dependency

It is not:

- bundled `twistysim.min.js` redistribution
- donor asset shipping
- broad playback-runtime ownership
- generic browser-viewer platform ownership
- generalized solver-backend ownership

## Current authority basis

This implementation packet stands on:

- `docs/REPO_LICENSE_TRACKING.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/ROADMAP.md`
- `docs/arch/HYPERTWIST_PHASE6R_AT_RUBIX_CUBE_SOLVER_TWISTYSIM_ASSET_REVIEW_BOUNDARY_PREPARATION_PACKET_2026-05-31.md`

The retained owner remains:

- `vivaansinghvi07/rubix-cube-solver`

The broader shell owners do not change here:

- first-party HyperTwist remains the owner for the actual browser shell,
  correction shell, and solve-explanation shell
- the landed shared correction and solve-unlock seams remain first-party

## Landed scope

The current code now owns one bounded browser-asset review seam through:

- retained recognition contract types for:
  - `FHyperTwistVisionBrowserAssetReviewDescriptor`
  - `FHyperTwistVisionBrowserAssetReviewProfile`
- bounded browser-shell review-profile ids/definitions and supported descriptor
  routing for the retained `twistysim.min.js` asset
- active browser-shell-state exposure for the chosen review descriptor
- focused automation coverage in:
  - `HyperTwistRubixCubeSolverPhase6RATTwistyAssetReviewContractTest.cpp`

## Why this is still intentionally bounded

This packet closes the explicit review-visibility gap without widening into
shipping or broad playback/runtime ownership.

Still deferred:

- donor asset redistribution
- donor asset shipping
- broad playback-runtime ownership
- generic browser-viewer platform ownership
- generalized solver-backend ownership

## Validation

Focused automation validation:

- `Automation RunTests HyperTwist.Permissive.RubixCubeSolver.Phase6R.AT`

Source-level validation on the VPS:

- `git diff --check`

## Queue effect

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

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

- landed now:
  - committed-face reconstruction session
  - face-vote replacement ledger
  - final classic-net shaping
  - browser/webcam shell profile and browser-shell session-state composition
  - bounded solve explanation/recommendation stage ladder and recommendation
    state
  - bundled browser visualization asset review boundary
  - bounded correction profile and correction-resolution closure above the row
- still deferred:
  - donor asset redistribution
  - donor asset shipping
  - broad playback-runtime ownership
  - generalized solver-backend ownership

The next clean move is:

- no new `rubix-cube-solver` widening by default unless a real provenance-safe
  shipping path or a narrower first-party playback/viewer gap is later proven
