+# 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.
+
+## 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

+## 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`

+
+## 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.
+
+The next bounded move is `Phase 2R-C`: packetize the remaining `0R-B` adjunct and alternative-support rows `cahidenes/rubiks-cube-solver`, `tentone/rubix-solver`, `NuiLab/code-vr`, `pissang/claygl`, and `pissang/clay-viewer` so no `0R-B` row remains on broad inherited routing.
