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

Created on `2026-05-31`

## Status

- first-party HyperTwist packet
- bounded permissive `Phase 6R-AT` preparation/control slice

## Purpose

This packet freezes one narrower retained widening above the already landed
`Phase 6R-P` browser-shell seam and `Phase 6R-Q` solve-explanation seam.

The intended kept value is:

- a first-party browser-asset review profile for the retained
  `vivaansinghvi07/rubix-cube-solver` browser shell
- explicit review-descriptor routing for the bundled `twistysim.min.js` asset
- active browser-shell visibility for the chosen review descriptor
- explicit visibility that bundled donor-asset shipping still stays deferred

This packet does not open:

- 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 preparation packet stands on:

- `docs/REPO_LICENSE_TRACKING.md`
- `docs/v6_5_deep_manual_pack/HyperTwist/ROADMAP.md`
- `docs/arch/HYPERTWIST_PHASE6R_P_RUBIX_CUBE_SOLVER_BROWSER_WEBCAM_SHELL_IMPLEMENTATION_PACKET_2026-05-25.md`
- `docs/arch/HYPERTWIST_PHASE6R_Q_RUBIX_CUBE_SOLVER_SOLVE_EXPLANATION_RECOMMENDATION_IMPLEMENTATION_PACKET_2026-05-25.md`
- `C:\Workspaces\HyperTwist\mirrors\permissive\vivaansinghvi07\rubix-cube-solver\LICENSE`
- `C:\Workspaces\HyperTwist\mirrors\permissive\vivaansinghvi07\rubix-cube-solver\frontend\src\script.js`
- `C:\Workspaces\HyperTwist\mirrors\permissive\vivaansinghvi07\rubix-cube-solver\frontend\lib\twistysim.min.js`

## Why this slice is justified

The already landed browser-shell and solve-explanation seams preserve the
transport, stage-routing, manual-edit handoff, and bounded explanation ladder,
but they do not yet expose a clean first-party contract for reviewing the
bundled third-party browser visualization asset boundary.

The donor exposes a narrow remaining layer:

- a bundled minified browser visualization asset that is visibly present in the
  checked frontend row
- browser-shell surfaces that imply an embedded visualization dependency
- a provenance and license boundary that should stay explicit before any
  shipping decision is made

So the correct next retained move is not donor-asset shipping and not broad
playback-runtime ownership. It is the narrower first-party review boundary that
keeps the asset-review truth visible while preserving the shipping defer line.

## Acceptance shape

The bounded `Phase 6R-AT` slice may land:

- browser-asset review profile ids and definitions in the live recognition
  contracts
- a bounded supported-review-descriptor list for the browser shell
- active browser-shell-state exposure for the chosen review descriptor
- focused automation for:
  - browser asset review-profile alignment
  - twistysim descriptor routing
  - explicit donor-asset defer visibility

The slice must keep these exclusions explicit:

- no donor asset incorporation or shipping
- no broad playback/runtime owner widening
- no generalized browser-viewer platform replacement

## Queue effect

If this packet lands, it consumes the current `Phase 6R-AT` widening slice.

The next clean move after landing should be:

- 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
