# HyperTwist Phase 6R-J roice3/MagicCube5D runtime profile and persistence preparation packet

Created on `2026-05-22`

## Status

- first-party HyperTwist packet
- source-backed permissive `Phase 6R-J` preparation/control slice

## Purpose

This packet narrows the retained `roice3/MagicCube5D` row before implementation.

The retained first slice is:

- dedicated `5D` family runtime-profile and persistence boundary beneath the retained
  `Hyperspeedcube` runtime anchor

It is not:

- a broad hyper-runtime platform packet
- a renderer or viewer-shell packet
- a generalized topology packet
- a generic notation or replay packet
- a broad macro/tutorial shell packet

## Source-backed basis

Primary donor surfaces inspected:

- `README.md`
- `src/MagicCube5D/workFiles/cube5D.h`
- `src/MagicCube5D/workFiles/cube5D.cpp`
- `src/MagicCube5D/workFiles/settings.cpp`
- `src/MagicCube5D/workFiles/stateTransformer.h`
- `src/MagicCube5D/workFiles/stateTransformer.cpp`
- `src/MagicCube5D/workFiles/loader.cpp`
- `src/MagicCube5D/workFiles/twist.h`

## Narrowing decision

The strongest bounded donor seam is not the WinForms/OpenGL host shell or the stereo/anaglyph
renderer. `Hyperspeedcube` already owns the primary retained runtime anchor and `MagicTile`
already owns the generalized topology and non-Euclidean lane.

The smallest stronger `MagicCube5D` seam is:

- order-parametric `5D` cube-family runtime semantics
- ten-face state encoding and cubie-index mapping
- click-derived twist selection and fifth-axis view-rotation behavior
- cubie-class solved-progress telemetry
- family-specific file-header, compact twist-history, and macro-sidecar persistence

The first bounded implementation packet should therefore land only:

- a first-party `MagicCube5D` reference bundle with:
  - source package references
  - one runtime-profile contract
  - one persistence boundary
  - one attribution boundary
- runtime-library accessors for that bounded reference bundle
- focused automation around:
  - runtime profile
  - persistence boundary
  - package checklist

## Explicit deferrals

Still deferred after this control pass:

- WinForms/OpenGL host-shell ownership
- stereo/anaglyph renderer ownership
- generic hyper-runtime ownership
- generic notation or replay ownership
- broad macro/tutorial shell widening
- broader `Hyperspeedcube` deepening beyond the next bounded packet

## Queue effect

This preparation packet authorizes one bounded permissive implementation packet:

- `Phase 6R-J` dedicated `MagicCube5D` family runtime-profile and persistence boundary

After that packet, move the queue head to:

- source-backed `Phase 6R-K` `HactarCE/Hyperspeedcube` notation/serialization preparation/control
  pass

Keep the legal and routing guards visible:

- `roice3/MagicCube5D`
  - keep the code-license judgment anchored on the mirrored `MIT` repo while preserving the older
    zip only as provenance context
  - keep the landed slice bounded to the dedicated `5D` family lane rather than a broad
    host-shell or renderer packet
- `HactarCE/Hyperspeedcube`
  - keep the next widening slice bounded to notation/serialization rather than reopening the whole
    deferred runtime-anchor remainder in one packet
