+# HyperTwist Phase 2R Packet 2R-C Ownership And Acceptance Contract
+
+Created on `2026-05-13`
+
+## Status
+
+`Phase 2R / Packet 2R-C` is now `closed`.
+
+This packet converts the final retained `0R-B` residual 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:
+
+- what these five residual permissive rows are allowed to own in first-party HyperTwist
+- what they are explicitly not allowed to own
+- which of them are comparison adjuncts versus optional alternative-support lanes
+- which first-party contracts must exist before widening is accepted
+- which later packet each row may enter next
+
+## Purpose
+
+`Phase 2R-A` closed the core runtime, recognition, timer, and topology rows.
+
+`Phase 2R-B` closed the primary permissive support-plane rows.
+
+`Phase 2R-C` closes the remaining ownership gap inside `0R-B` for:
+
+- recognition comparison adjuncts behind the retained recognition anchors
+- symbolic-to-spatial XR pedagogy experiments
+- alternative browser comparison lanes that stay subordinate to the retained browser stack
+
+Without this packet, the final `0R-B` rows would still sit on inherited routing without explicit ownership and acceptance boundaries.
+
+## Scope
+
+This packet closes ownership and acceptance for:
+
+- `cahidenes/rubiks-cube-solver`
+- `tentone/rubix-solver`
+- `NuiLab/code-vr`
+- `pissang/claygl`
+- `pissang/clay-viewer`
+
+These five rows stay retained.
+
+None of them are promoted into product-foundation owners.

+
+Document responsibilities are strict:
+
+- `0R-B` owns source-value extraction and exclusion rationale
+- `REPO_LICENSE_TRACKING.md` owns repo-row legal detail
+- `2R-A` owns the retained recognition anchors
+- `2R-B` owns the primary support-plane owners
+- this packet owns the residual `0R-B` adjunct and alternative-support rows
+
+## Packet licensing snapshot
+
+- `MIT`: `cahidenes/rubiks-cube-solver`, `tentone/rubix-solver`, `NuiLab/code-vr`
+- `BSD-style permissive`: `pissang/claygl`
+- `BSD-3-Clause`: `pissang/clay-viewer`
+
+## Packet result
+
+`2R-C` freezes the following routing:
+
+- `cahidenes/rubiks-cube-solver` and `tentone/rubix-solver` are now a retained recognition-comparison adjunct lane, not a primary recognition lane
+- those two rows may widen only later through `Phase 6R-E`, after the retained recognition anchors are already fixed
+- `NuiLab/code-vr` is now a retained symbolic-to-spatial XR pedagogy experiment lane only
+- `NuiLab/code-vr` may widen only later through `Phase 6R-F`, after the retained knowledge and XR support lanes already exist
+- `pissang/claygl` and `pissang/clay-viewer` are now an optional alternative browser comparison lane beneath the retained browser stack
+- those two rows may widen only later through `Phase 3R-G`, and only if the primary retained browser stack leaves a real gap
+- none of these rows are newly proven live in checked Unreal surfaces
+
+Important correction:
+
+- all retained `0R-B` rows now have explicit ownership and acceptance packetization
+- the earlier inherited routing for the final five residual `0R-B` rows is now superseded
+- `cahidenes/rubiks-cube-solver` and `tentone/rubix-solver` are not general `Phase 3R` permissive implementation candidates
+- `NuiLab/code-vr` is not the practical browser XR runtime owner
+- `pissang/claygl` and `pissang/clay-viewer` are not equal alternatives to the primary retained browser stack
+
+Implementation entry result:
+
+| Repo or lane | Ownership class | Earliest widening phase | Packet entry |
+| --- | --- | --- | --- |
+| `cahidenes/rubiks-cube-solver` | face-placement and cube-string comparison adjunct | `Phase 6R` | `6R-E` |

+| `NuiLab/code-vr` | symbolic-to-spatial XR pedagogy experiment donor | `Phase 6R` | `6R-F` |
+| `pissang/claygl` | alternative browser `3D` comparison substrate | `Phase 3R` only if a real gap remains | `3R-G` |
+| `pissang/clay-viewer` | alternative browser viewer/editor comparison sidecar | `Phase 3R` only if a real gap remains | `3R-G` |

+- define a first-party cube-string assembly cross-check contract with orientation, completeness, and divergence outputs
+- define a low-confidence or disagreement-reporting surface between the primary recognition path and the adjunct comparator
+- explicitly record that the two-opposite-corner assumption is optional comparison logic, not a product-wide invariant

+
+### `tentone/rubix-solver`
+
+Ownership granted:
+

+- do not let its local camera shell become a retained product surface
+
+Acceptance markers before widening may start:

+- define a payload-compatibility contract between native comparison output and the retained recognition stack
+- explicitly exclude the brute-force solve shell from owned functionality

+### `NuiLab/code-vr`
+
+Ownership granted:
+
+- first-party symbolic-to-spatial pedagogy experiment contract
+- AST or graph-to-scene representation experiment boundary
+- multi-process teaching-sidecar concept boundary for parse/export/runtime separation
+
+Ownership denied:

+- define an import/export boundary from first-party pedagogical structures into a spatial scene representation
+- define the dependency boundary on the retained XR support stack rather than letting this repo own that stack
+- explicitly record that language-specific parsing examples are concept references, not direct implementation targets

+- define which narrow sidecar or explainer surface would justify alternative substrate use before any implementation starts
+
+Earliest widening route:
+
+- `Phase 3R / Packet 3R-G`
+
+### `pissang/clay-viewer`
+
+Ownership granted:

+- do not let this repo replace `google/model-viewer` as the primary browser presentation and compact editor lane
+- do not let it expand into gameplay, simulator, puzzle-renderer, or runtime-foundation ownership
+- do not widen it without a concrete comparison case that the primary browser viewer lane cannot satisfy cleanly
+
+Acceptance markers before widening may start:
+
+- define explicit comparison criteria against the retained `google/model-viewer` lane
+- define the bounded sidecar or preview workflow that would justify an alternative viewer/editor lane
+- define the no-displacement rule that keeps this lane subordinate even if it is later used
+- record that the `baidu/san` dependency context remains folded as commodity framework context, not a separate donor lane
+
+Earliest widening route:
+
+- `Phase 3R / Packet 3R-G`
+
+## Dependency order
+
+The packeted dependency order is now explicit:
+
+1. `cahidenes/rubiks-cube-solver` and `tentone/rubix-solver` may widen only after the retained recognition anchors from `2R-A` are fixed, because they are comparison adjuncts rather than primary owners
+2. `pissang/claygl` and `pissang/clay-viewer` may widen only after the primary browser-side viewer and substrate lanes from `2R-B` already exist and still leave a real gap
+3. `NuiLab/code-vr` may widen only after both the retained knowledge lane and the retained XR support lane already exist, because its value is experimental symbolic-to-spatial pedagogy rather than practical runtime ownership
+
+## Packet-close result
+
+`Phase 2R-C` is now closed as the ownership and acceptance authority for the final residual `0R-B` rows above.
+
+This closes `Phase 2R` for the retained permissive set.
+
+The next bounded move is `Phase 3R-A`: widen `Aarav2709/KubeTimr` as the bounded timer, inspection, splits, stats, persistence, and timer-scoped replay entry lane.
