# HyperTwist hypercubing.xyz Reference Incorporation Provenance Board - 2026-05-27

## Status

This document is the source-backed provenance and hierarchy note for the live
repo-backed reference-incorporation side currently materialized from
`Hypercubers/hypercubing.xyz`.

It closes the source-specific reference side that remained implicit after the
landed `Phase 3R-B` packet and the broader live-lane audit.

It answers one narrow question:

- do the live `Hypercubers/hypercubing.xyz` reference targets reopen already
  landed first-party hypercubing knowledge, notation, progression, software
  matrix, and leaderboard/report implementation, or do they instead need a
  reference-side provenance-board and canon backfill

Result:

- no product-code reopening is required
- yes reference-side provenance-board and feature-canon backfill is required

## Counts confirmed from current first-party materialization

Current live `Hypercubers/hypercubing.xyz` reference-incorporation targets:

- `4` total rewritten reference targets
- all `4` stay inside the already-landed `Phase 3R-B` bounded lane

Exact surfaces:

1. `reference/hypercubing-xyz-course-reference-page-progression`
   - `SurfaceType`: `course-reference`
   - `TrackTitle`: `Hypercubing Progression`
   - `IncorporationChannel`: `course-reference-supplement`
   - `TargetAssetFamily`: `reference-page`
2. `reference/hypercubing-xyz-notation-reference-page-cell-turning-hypercubes`
   - `SurfaceType`: `notation-reference`
   - `TrackTitle`: `Hypercubing Notation`
   - `IncorporationChannel`: `notation-reference-supplement`
   - `TargetAssetFamily`: `glossary-page`
3. `reference/hypercubing-xyz-tool-reference-page-software-matrix`
   - `SurfaceType`: `tool-reference`
   - `TrackTitle`: `Hypercubing Software`
   - `IncorporationChannel`: `feature-reference`
   - `TargetAssetFamily`: `tool-note`
4. `reference/hypercubing-xyz-community-reference-page-leaderboards`
   - `SurfaceType`: `community-reference`
   - `TrackTitle`: `Hypercubing Leaderboards`
   - `IncorporationChannel`: `community-reference-supplement`
   - `TargetAssetFamily`: `leaderboard-note`

Important adjacent fact:

- all four targets preserve progression ordering, notation grammar,
  software-comparison taxonomy, and leaderboard display-rule semantics already
  enforced by the landed lane
- these targets stay in the knowledge/reference family and do not widen into
  runtime simulation, solver execution, timer execution, or host-shell
  ownership

## Slice-local verdict

| Slice | Primary authority | Secondary value kept | Result |
|---|---|---|---|
| First-party hypercubing knowledge, notation, progression, software matrix, and leaderboard/report implementation | first-party current code plus landed `Phase 3R-B` packet | retained `Hypercubers/hypercubing.xyz` reference targets stay subordinate provenance-grounding surfaces | unchanged live implementation owner |
| Rewritten progression, notation, and software-matrix grounding | `Hypercubers/hypercubing.xyz` retained permissive lane | factual stage order, prerequisite logic, notation grammar, and software-capability taxonomy are preserved while prose remains first-party | unchanged retained reference-grounding surface beneath first-party contracts |
| Rewritten leaderboard conventions grounding | `Hypercubers/hypercubing.xyz` retained permissive lane | event naming, format semantics, relative-date posture, and solver/program-badge conventions stay explicit in first-party notes | unchanged bounded community-reference surface |

## Why no product-code reopening is required

The live surfaces here are already rewritten first-party targets, not copied
donor docs, donor site shell, donor HTML output, or a silent upstream private
fork.

The checked targets explicitly require:

- preserving bounded progression ordering, notation grammar, software
  comparison, and leaderboard-contract semantics
- rewriting page titles, donor instructional prose, donor-specific examples,
  donor presentation formatting, and donor HTML or site-shell output

That means the retained surfaces are provenance and factual grounding, not
donor site or runtime ownership.

So this pass does not reopen:

- the closed `Phase 3R-B` first-party knowledge-reference lane
- any higher-dimensional runtime, topology, or simulation owner lane
- any timer, recognition, or solver-execution owner lane
- any host application shell or static-site architecture ownership posture

## Current exact grounded role

`Hypercubers/hypercubing.xyz` currently grounds four live rewritten first-party
contract/reference targets:

- hypercubing progression ladder
- cell-turning hypercube notation
- hypercubing software matrix
- hypercubing leaderboard conventions

These targets preserve bounded hypercubing knowledge semantics while keeping
all surfaced prose and shell framing first-party.

## Backfill result

### Earlier incorporation audit reopened

- `C:\HyperTwist\docs\HT_REPO_INCORPORATION_AUDIT_2026-05-11.md`

### Feature canon reopened

- `C:\HyperTwist\docs\v6_5_deep_manual_pack\HyperTwist\FEATURE_REGISTRY.md`

## Final call

The live `Hypercubers/hypercubing.xyz` reference-incorporation side is now
explicit:

- `4` rewritten first-party contract/reference targets
- all `4` remain inside the landed `Phase 3R-B` knowledge-reference lane
- progression, notation, software-matrix, and leaderboard/report grounding stay
  explicit

This closes the `Hypercubers/hypercubing.xyz` reference side without reopening
product code.
