# HyperTwist remotion 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
`remotion-dev/remotion`.

It closes the source-specific reference side that remained implicit after the
landed `Phase 4R-F` packet and the broader live-lane and commercial-boundary
audits.

It answers one narrow question:

- do the live `remotion-dev/remotion` reference targets reopen already landed
  first-party media-export, embedded-playback, parser, and explainer support
  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 `remotion-dev/remotion` reference-incorporation targets:

- `5` total rewritten reference targets
- all `5` are under `Media Export and Replay Explainers`
- all `5` stay inside the already-landed `Phase 4R-F` bounded lane

Exact surfaces:

1. `reference/remotion-embedded-playback-reference-page`
   - `SurfaceType`: `media-export-embedded-playback-reference`
   - `IncorporationChannel`: `embedded-playback-contract`
   - `TargetAssetFamily`: `embedded-playback-note`
2. `reference/remotion-render-orchestration-reference-page`
   - `SurfaceType`: `media-export-render-reference`
   - `IncorporationChannel`: `render-orchestration-contract`
   - `TargetAssetFamily`: `render-orchestration-note`
3. `reference/remotion-media-parser-reference-page`
   - `SurfaceType`: `media-export-parser-reference`
   - `IncorporationChannel`: `media-parser-contract`
   - `TargetAssetFamily`: `media-parser-note`
4. `reference/remotion-explainer-studio-reference-page`
   - `SurfaceType`: `media-export-studio-reference`
   - `IncorporationChannel`: `explainer-studio-contract`
   - `TargetAssetFamily`: `explainer-studio-note`
5. `reference/remotion-compliance-boundary-reference-page`
   - `SurfaceType`: `media-export-compliance-boundary-reference`
   - `IncorporationChannel`: `compliance-boundary`
   - `TargetAssetFamily`: `compliance-boundary-note`

Important adjacent fact:

- all five targets preserve the explicit commercial-license and package-split
  boundary already enforced by the landed lane

## Slice-local verdict

| Slice | Primary authority | Secondary value kept | Result |
|---|---|---|---|
| First-party media-export, embedded-playback, parser, and explainer support implementation | first-party current code plus landed `Phase 4R-F` packet | retained `remotion-dev/remotion` reference targets stay subordinate provenance-grounding surfaces | unchanged live implementation owner |
| Rewritten embedded playback, render orchestration, media parser, and explainer-studio grounding | `remotion-dev/remotion` retained boundary-sensitive lane | factual playback, render, parser, and preview/output semantics are preserved while prose remains first-party | unchanged retained reference-grounding surface beneath first-party contracts |
| Commercial-license and package-split compliance boundary grounding | `remotion-dev/remotion` retained boundary-sensitive lane | the checked root-license posture and `@remotion/studio` versus player or renderer or parser split stay explicit in a first-party compliance note | unchanged bounded compliance-grounding surface |

## Why no product-code reopening is required

The live surfaces here are already rewritten first-party targets, not copied
donor pages or donor product-shell UI.

The checked targets explicitly require:

- preserving factual playback, render, parser, preview/output, and compliance
  semantics
- rewriting donor wording, donor authoring-shell framing, and any broader
  product, template, deployment, or marketing assumptions

That means the retained surfaces are provenance and factual grounding, not
donor shell ownership.

So this pass does not reopen:

- the closed `Phase 4R-F` first-party media-export lane
- the broader browser/spatial/media adjunct family
- any whole-Remotion product-shell inheritance
- any package-split or commercial-license flattening

## Current exact grounded role

`remotion-dev/remotion` currently grounds five live rewritten first-party
contract/reference targets for `Media Export and Replay Explainers`:

- embedded playback and controls
- render orchestration and export registration
- media parser, worker, and seeking posture
- explainer-studio preview and output registration
- commercial-sidecar and package-split compliance boundary

These targets preserve bounded media-export and replay-explainer semantics
while keeping all surfaced prose and product 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 `remotion-dev/remotion` reference-incorporation side is now explicit:

- `5` rewritten first-party contract/reference targets
- all `5` remain inside the landed `Phase 4R-F` media-export lane
- the commercial-license and package-split boundary stays explicit

This closes the `remotion-dev/remotion` reference side without reopening
product code.
