# HyperTwist Phase 6R-D MagicTile tiling topology implementation packet

Created on `2026-05-21`

## Status

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

## Purpose

This packet lands the first narrower bounded slice from the retained `roice3/MagicTile`
non-Euclidean topology row.

The landed slice is:

- first-party tiling topology and geometry-family contract plus loader/runtime-anchor boundary

It is not:

- a full `MagicTile` row transplant
- a `Hyperspeedcube` runtime-base replacement
- a transform-aware macro remapping packet
- a WinForms/OpenTK host-shell packet
- a broad non-Euclidean interaction shell
- the speech-input / voice sidecar packet

## Current authority basis

This implementation packet stands on:

- `docs/HYPERTWIST_PHASE_0R_PACKET_0R_A_EVALUATION_2026-05-12.md`
- `docs/HYPERTWIST_PHASE_2R_PACKET_2R_A_OWNERSHIP_AND_ACCEPTANCE_CONTRACT_2026-05-13.md`
- `docs/REPO_LICENSE_TRACKING.md`
- `docs/arch/HYPERTWIST_PHASE6R_D_MAGICTILE_TOPOLOGY_PREPARATION_PACKET_2026-05-21.md`

The retained owner remains:

- `roice3/MagicTile`

The granted family remains bounded to:

- tiling topology analysis
- non-Euclidean geometry-family descriptors
- topology-derived loader boundary
- direct-donor attribution boundary

This packet lands only the first narrower family in that granted set.

## Landed scope

The current code now owns a retained tiling-topology contract through:

- new first-party tiling contract types for:
  - package references
  - topology contract
  - loader boundary
  - attribution boundary
  - reference bundle
- bundled `MagicTile` reference-bundle construction in:
  - `UHyperTwistTrainingTilingLibrary`
- runtime-library accessors for:
  - bundled tiling reference bundle
  - topology-contract lookup
  - loader-boundary lookup
  - attribution-boundary lookup
  - package checklist export
- focused automation coverage in:
  - `HyperTwistMagicTilePhase6RDTopologyContractTest.cpp`

The landed bundle preserves the bounded donor package basis:

- `package/magictile-topology-analyzer`
- `package/magictile-loader`
- `package/magictile-puzzle-core`
- `package/magictile-tiling-geometry`
- `package/magictile-polytope-geometry`
- `package/magictile-h3-honeycomb`

## Why this is still intentionally bounded

This packet lands the first donor-backed topology and geometry-family contract seam, but it does
not widen into the neighboring retained families.

Still deferred:

- transform-aware macro remapping
- broad non-Euclidean viewer or editor shell
- WinForms/OpenTK host-shell ownership
- runtime-base replacement above `Hyperspeedcube`
- the speech-input / voice sidecar queue

## Validation

Build validation:

- `Build.bat UnrealHyperTwistEditor Win64 Development -Project='C:\HyperTwist\UnrealHyperTwist\UnrealHyperTwist.uproject' -WaitMutex -NoHotReloadFromIDE`

Focused automation validation:

- `Automation RunTests HyperTwist.Permissive.MagicTile.Phase6R.D`

Regression automation validation:

- `Automation RunTests HyperTwist.Permissive.Qbr.Phase6R.B`
- `Automation RunTests HyperTwist.Permissive.Hyperspeedcube.Phase6R.A`
- `Automation RunTests HyperTwist.CleanRoom.CubeDesk`

Expected covered tests:

- `TopologyContract`
- `LoaderBoundary`
- `PackageChecklist`
- `CalibrationSessionConfig`
- `PreviewObservation`
- `CommitObservation`
- `CatalogLookup`
- `SampleDefinition`
- `TrainingRunDefinition`
- existing `CubeDesk` clean-room regression suite

## Queue effect

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

`roice3/MagicTile` remains only partially incorporated:

- landed now:
  - tiling topology and geometry-family contract
  - loader/runtime-anchor boundary
  - direct-donor attribution boundary
- still deferred:
  - transform-aware macro remapping
  - broad non-Euclidean interaction shell
  - WinForms/OpenTK host shell

The next clean move is not another immediate `MagicTile` widening by default.

The next queue head should be:

- a source-backed `Phase 6R-E` speech-input / voice sidecar preparation/control pass, starting
  with `ggml-org/whisper.cpp`

Keep the future sequencing guards visible:

- `Phase 6R-B` `kkoomen/qbr`
  - do not copy or redistribute `src/assets/arial-unicode-ms.ttf` without separate confirmation
    or replacement if any future widening ships that asset
- `Phase 6R-C` `vivaansinghvi07/rubix-cube-solver`
  - do not copy or redistribute `frontend/lib/twistysim.min.js` without preserving or replacing
    its upstream provenance/license if any future widening ships that dependency
- `Phase 6R-E` speech-input / voice sidecar set
  - keep code-license judgments separate from model, voice, or payload-license review
