# HyperTwist Repo-Backed Reference Incorporation Closure Sweep - 2026-05-27

## Status

This document is the final closure sweep for the current repo-backed
reference-incorporation set materialized in the live HyperTwist training
catalog.

It answers one narrow question:

- after the individual provenance-board passes, do any repo-backed live
  reference targets still remain implicit, duplicated, or mismapped in canon

Result:

- no product-code reopening is required
- no further repo-backed provenance-board pass is required for the current
  materialized target set
- yes one canon-level closure note and normalization backfill is required

## Counts confirmed from current first-party materialization

Current repo-backed reference-incorporation coverage in
`hypertwist-reference-incorporation-targets.json`:

- `71` total rewritten first-party reference targets
- `24` distinct `SourceRepo` identities
- `20` dedicated provenance-board notes

The `24` source identities are fully resolved in canon through three patterns:

1. one-source-one-board rows such as `apache/echarts`, `cubing/cubing.js`,
   `screenpipe/screenpipe`, and `remotion-dev/remotion`
2. the combined `superliminal.com` / `Superliminal Wiki` board, which covers
   both retained hypercubing reference surfaces without splitting them into
   false owner lanes
3. the root `google/model-viewer` board, which covers the root viewer lane plus
   three support-only subpackage source attributions:
   - `google/model-viewer/packages/space-opera`
   - `google/model-viewer/packages/modelviewer.dev`
   - `google/model-viewer/packages/render-fidelity-tools`

`google/model-viewer/packages/shared-assets` remains intentionally separate
because it is a distinct boundary-sensitive fixture lane rather than a
subordinate support-only contributor.

## Closure-sweep verdict

| Check | Result | Notes |
|---|---|---|
| Any repo-backed reference family still missing a provenance board | no | All `24` source identities are now resolved through explicit boards or deliberate absorbed-support posture. |
| Any repo-backed live family duplicated as a second owner lane | no | The `google/model-viewer` support trio is absorbed under the root viewer board; `KhronosGroup/glTF-Sample-Viewer` and `shared-assets` remain separate by design. |
| Any product packet reopened by this sweep | no | The sweep only normalizes canon around already landed reference-side owners. |
| Any repo-state-board lane reclassification required | no | Existing repo rows already describe the absorbed subpackages as subordinate, separately non-live packages beneath the landed root lane. |

## Why no further repo-backed provenance board is required

The only potential ambiguity left after the individual repo passes was the
`google/model-viewer` family.

The live target set uses four source identities there:

- `google/model-viewer`
- `google/model-viewer/packages/space-opera`
- `google/model-viewer/packages/modelviewer.dev`
- `google/model-viewer/packages/render-fidelity-tools`

Those targets do not create four live owner lanes.

They remain one landed first-party `Phase 3R-D` browser-viewer family with:

- the root lane as the live owner-facing reference ground
- `space-opera` as subordinate compact-editor and inspection support
- `modelviewer.dev` as subordinate snippet/docs/demo infrastructure support
- `render-fidelity-tools` as subordinate renderer-comparison and fidelity
  support

That absorbed-support split is already consistent with the repo state board and
the root `google/model-viewer` provenance note. This closure sweep only makes
that normalization explicit at the canon level so the materialized target file
and the human-readable audit no longer look like they disagree.

## Current exact grounded role

The repo-backed reference-incorporation cluster is now closed for the current
materialized target set:

- `71` rewritten first-party targets
- `24` distinct source identities
- all source identities resolved through explicit provenance notes or explicit
  absorbed-support posture
- no skipped repo-backed family
- no duplicate live owner lane

## 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 current repo-backed reference-incorporation set is now canonically closed:

- all `71` current repo-backed targets are accounted for
- all `24` source identities are resolved
- the `google/model-viewer` support trio is intentionally absorbed beneath the
  root viewer lane instead of creating false extra live owner lanes
- no further repo-backed provenance-board pass is required for the current
  materialized target set

The next clean move is outside this cluster: return to the broader repo state
board, feature canon, and live-lane audit for the next non-reference or
non-repo provenance decision rather than opening another repo-backed
reference-incorporation note by default.
