# HyperTwist Phase 2R Packet 2R-B Ownership And Acceptance Contract

Created on `2026-05-13`

## Status

`Phase 2R / Packet 2R-B` is now `closed`.

This packet converts the primary retained `0R-B` support-plane rows from source-evaluated donors into implementation-ready ownership contracts.

It does not redo source parsing.

That source-value work already lives in:

- [HYPERTWIST_PHASE_0R_PACKET_0R_B_EVALUATION_2026-05-12.md](C:/HyperTwist/docs/HYPERTWIST_PHASE_0R_PACKET_0R_B_EVALUATION_2026-05-12.md:1)
- [REPO_LICENSE_TRACKING.md](C:/HyperTwist/docs/REPO_LICENSE_TRACKING.md:1)

This packet answers the next question instead:

- which retained permissive support-plane repos are allowed to own specific first-party browser-side or support-side subsystems
- which repos are only subordinate packages, helper layers, or QA sidecars beneath stronger anchors
- which first-party contracts must exist before widening is accepted
- which `Phase 3R` packet each lane may enter next
- which `0R-B` rows are still not part of the support-plane packet and must wait for `2R-C`

## Purpose

`Phase 2R-A` closed ownership for the core runtime, recognition, timer, and topology rows.

`Phase 2R-B` closes the next ownership gap for the retained permissive support plane:

- knowledge, curriculum, notation, and community surfaces
- analytics and reporting surfaces
- browser presentation, inspection, editor, and QA sidecars
- embodied companion surfaces
- browser-side `3D`, XR, spatial UI, effect, state, gesture, and motion support stacks

Without this packet, future instances would still be able to widen the right support repos for the wrong reasons.

## 2026-05-14 ownership-routing clarification

This packet records ownership and acceptance boundaries for retained support-plane rows.

It does not collapse the earlier evaluation states into one vague approval signal.

For every row in this packet, future instances must still keep separate:

- bookmarked = intake only
- queued = sequencing only
- source-read = evidence gathered
- retained = survived evaluation
- product-fit = separate judgment that the retained value belongs in HyperTwist direction
- implementation-authorized = explicit bounded phase entry approval
- implemented = actually landed in first-party product surfaces

Therefore:

- appearance in this packet is not a claim that earlier bookmark or queue position had merit value
- retained status here is not proof of broad product ownership beyond the bounded lane described here
- phase entry permission here is not proof that implementation has already happened

Use [HYPERTWIST_REPO_INTAKE_RETENTION_AND_PRODUCT_FIT_DOCTRINE_2026-05-14.md](C:/HyperTwist/docs/HYPERTWIST_REPO_INTAKE_RETENTION_AND_PRODUCT_FIT_DOCTRINE_2026-05-14.md:1) for the state vocabulary and [HYPERTWIST_MODEL_A_MODEL_B_COORDINATOR_DOCTRINE_2026-05-14.md](C:/HyperTwist/docs/HYPERTWIST_MODEL_A_MODEL_B_COORDINATOR_DOCTRINE_2026-05-14.md:1) for the authority-path reading rule.

## Scope

This packet closes ownership and acceptance for these retained `0R-B` rows:

- `Hypercubers/hypercubing.xyz`
- `apache/echarts`
- `ecomfe/zrender`
- `ecomfe/echarts-gl`
- `KhronosGroup/glTF-Sample-Viewer`
- `KhronosGroup/glTF-Sample-Renderer`
- `google/model-viewer`
- `google/model-viewer/packages/model-viewer-effects`
- `google/model-viewer/packages/modelviewer.dev`
- `google/model-viewer/packages/render-fidelity-tools`
- `google/model-viewer/packages/space-opera`
- `met4citizen/TalkingHead`
- `mrdoob/three.js`
- `pmndrs/postprocessing`
- `pmndrs/react-postprocessing`
- `pmndrs/react-three-fiber`
- `pmndrs/drei`
- `pmndrs/xr`
- `pmndrs/uikit`
- `pmndrs/three-stdlib`
- `pmndrs/maath`
- `pmndrs/zustand`
- `pmndrs/leva`
- `pmndrs/use-gesture`
- `pmndrs/react-spring`
- `@react-spring/core`
- `@react-spring/shared`
- `@react-spring/types`
- `@react-spring/parallax`
- `@react-spring/rafz`
- `@react-spring/animated`

This packet does **not** close the remaining `0R-B` adjunct or comparison rows.

Those rows remain pending for `Phase 2R-C`:

- `cahidenes/rubiks-cube-solver`
- `tentone/rubix-solver`
- `NuiLab/code-vr`
- `pissang/claygl`
- `pissang/clay-viewer`

Reason for the split:

- `cahidenes/rubiks-cube-solver` and `tentone/rubix-solver` are recognition comparison adjuncts behind the `0R-A` recognition anchors, not support-plane owners
- `NuiLab/code-vr` is an XR pedagogy-pattern donor only, not the practical browser XR runtime owner
- `pissang/claygl` and `pissang/clay-viewer` are alternative browser comparison lanes subordinate to the retained `three.js` + `model-viewer` stack

## Authority boundary

Use the documents in this order for the repos in this packet:

1. this packet for subsystem ownership, acceptance markers, and `Phase 3R` packet entry
2. [HYPERTWIST_PHASE_0R_PACKET_0R_B_EVALUATION_2026-05-12.md](C:/HyperTwist/docs/HYPERTWIST_PHASE_0R_PACKET_0R_B_EVALUATION_2026-05-12.md:1) for source-value extraction and exclusion rationale
3. [REPO_LICENSE_TRACKING.md](C:/HyperTwist/docs/REPO_LICENSE_TRACKING.md:1) for license, attribution, notice, and provenance obligations

Document responsibilities are strict:

- `0R-B` owns source-value extraction and non-promotion rationale
- `REPO_LICENSE_TRACKING.md` owns repo-row legal detail
- this packet owns ownership boundaries, acceptance markers, and packet entry sequencing for the support-plane rows in scope

## Packet result

`2R-B` freezes the following support-plane routing:

- `Hypercubers/hypercubing.xyz` is the knowledge, curriculum, notation, and community anchor for `Phase 3R-B`
- `apache/echarts` is the analytics and reporting anchor for `Phase 3R-C`, with `ecomfe/zrender` and `ecomfe/echarts-gl` subordinate beneath it
- `google/model-viewer` is the browser presentation and editor anchor for `Phase 3R-D`
- `KhronosGroup/glTF-Sample-Viewer` remains a standards-aware QA and validation sidecar in `Phase 3R-D`, not a competing viewer foundation
- `met4citizen/TalkingHead` is the embodied companion anchor for `Phase 3R-E`
- `mrdoob/three.js`, `pmndrs/react-three-fiber`, and `pmndrs/xr` define the browser `3D` / XR support stack for `Phase 3R-F`
- `pmndrs/uikit`, `pmndrs/postprocessing`, `pmndrs/react-postprocessing`, `pmndrs/drei`, `pmndrs/three-stdlib`, `pmndrs/maath`, `pmndrs/zustand`, `pmndrs/leva`, `pmndrs/use-gesture`, `pmndrs/react-spring`, and `@react-spring/*` remain subordinate helper or dependency lanes inside `3R-F`
- none of these rows are newly proven live in checked Unreal surfaces

Important correction:

- the older broad reading that all `0R-B` rows simply re-enter as equal `Phase 3R` donors is now superseded
- some `0R-B` rows are now explicitly support-plane owners
- some are explicitly subordinate packages or helper layers beneath those owners
- the remaining `0R-B` comparison and alternative lanes are not closed by this packet and stay pending for `2R-C`

## Residual `0R-B` rows held for `2R-C`

These rows are still retained, but `2R-B` does not close them:

| Repo | Why it is not in `2R-B` | Expected next routing |
| --- | --- | --- |
| `cahidenes/rubiks-cube-solver` | recognition comparison adjunct behind the `0R-A` recognition anchors, not a support-plane owner | `Phase 2R-C`, then later `Phase 6R` only if reopened |
| `tentone/rubix-solver` | native recognition comparison adjunct behind the `0R-A` recognition anchors, not a support-plane owner | `Phase 2R-C`, then later `Phase 6R` only if reopened |
| `NuiLab/code-vr` | XR pedagogy and representation-pattern donor only, not the practical browser XR runtime owner | `Phase 2R-C` |
| `pissang/claygl` | alternative browser `3D` substrate subordinate to retained `three.js` lane | `Phase 2R-C` |
| `pissang/clay-viewer` | alternative browser viewer/editor sidecar subordinate to retained `model-viewer` lane | `Phase 2R-C` |

## Dependency order

The packeted dependency order is now explicit:

1. `Hypercubers/hypercubing.xyz` may widen early as `3R-B` because it owns reference and curriculum surfaces, not runtime foundation
2. `apache/echarts` may widen as `3R-C` before viewer and XR sidecars if reporting surfaces are needed early
3. `google/model-viewer` and `KhronosGroup/glTF-Sample-Viewer` widen together in `3R-D`, with standards QA explicitly subordinate to presentation/editor ownership
4. `met4citizen/TalkingHead` widens as `3R-E` only after the companion narration contract is explicit
5. `mrdoob/three.js`, `pmndrs/react-three-fiber`, and `pmndrs/xr` widen in `3R-F` only as browser-side support stacks and never as runtime-foundation replacements
6. the five residual `0R-B` rows above must wait for `2R-C` before any widening decision is considered final

## Packet-close result

`Phase 2R-B` is now closed as the ownership and acceptance authority for the retained permissive support-plane rows in scope above.

At the time `2R-B` closed, the next bounded move was `Phase 2R-C`.

That packet is now also closed.

Current forward routing now lives in:
