+
+Created on `2026-05-13`
+
+## Status
+
+`Phase 4R / Packet 4R-C` is now `closed`.
+
+This packet converts the retained boundary-sensitive `google/model-viewer/packages/shared-assets` row from a queued mixed-provenance fixture pack into a landed first-party HyperTwist shared-assets allowlist, provenance-boundary, and fixture-refresh lane.
+
+It does not reopen `Phase 0R`, `Phase 1R`, `Phase 2R`, `Phase 3R`, `Phase 4R-A`, or `Phase 4R-B`.
+
+Those earlier packets still own:
+
+- source-value extraction
+- retained-set routing
+- ownership and acceptance boundaries
+- landed browser viewer and browser spatial owner decisions
+- the landed classic-cubing and legacy `4D` boundary-sensitive preserve lanes
+
+This packet owns the next question instead:
+
+- what first-party shared-assets implementation actually landed
+- how the mixed per-asset terms were converted into an explicit allowlist and shipping boundary
+- which retained fixture value is now live
+- what remains review-only, local-only, or excluded
+- what validation was completed
+- what the next bounded implementation move is after this landing

+## Landed implementation scope
+
+What landed:
+
+- a first-party shared-assets fixture ledger covering:
+  - CC0 ship-eligible QA fixtures
+  - attribution-bound review fixtures
+  - Smithsonian review-only fixtures
+  - local-only noncommercial fixtures
+  - contributor-noted geometry smoke-test fixtures
+- a first-party allowlist contract that records:
+  - required fixture families
+  - ship-eligible fixture ids
+  - review-required fixture ids
+  - local-only fixture ids
+  - approved workflow tags
+- a first-party provenance and shipping boundary that records:
+  - allowed shipping fixtures
+  - notice-bound fixtures
+  - review-only fixtures
+  - excluded fixtures
+  - required notice actions
+  - provenance caveats
+- a first-party refresh pattern that preserves the fixture-sync and attribution-recheck workflow without automatic allowlist widening
+- first-party runtime-library accessors and TSV checklist export for the new shared-assets bundle
+- bundled first-party reference targets and raw source-reference capture for the allowlist, CC0 environment matrix, provenance boundary, refresh pattern, and contributed-geometry smoke-test boundary
+
+What that means in practice:
+
+- `google/model-viewer/packages/shared-assets` now owns the landed boundary-sensitive fixture and QA-pack preserve lane in HyperTwist
+- the landed surface is a first-party Unreal contract and runtime API, not a vague future donor note
+- the practical path is explicit per-asset allowlisting rather than blanket mixed-asset shipping
+- the landed `google/model-viewer` packet remains the primary browser viewer owner, while `shared-assets` now owns the explicit fixture/provenance sidecar beneath it
+
+## Preserved landed value
+
+The donor value that was actually promoted is:
+
+- explicit per-asset fixture family curation
+- explicit CC0 environment-lighting matrices for browser parity and capture workflows
+- explicit notice-bound versus review-only versus excluded asset splits
+- explicit provenance and attribution review rules carried forward from `ATTRIBUTIONS.md`
+- explicit fixture refresh and attribution-recheck discipline
+- explicit geometry-smoke-test and parser-fixture value without turning contributor-noted assets into blanket shipping assumptions
+
+## Excluded or non-promotion boundary
+
+Do not promote this packet into:
+
+- a blanket license to ship the full `shared-assets` package
+- silent inheritance of all mixed-provenance fixtures as product-owned assets
+- gameplay or runtime ownership
+- donor docs or example-shell ownership
+- removal of asset-level attribution, review, or noncommercial boundaries
+
+Rationale:
+
+- the package is valuable because it concentrates sample-fixture, HDRI, and provenance coverage for browser QA
+- its strongest value is explicit fixture selection and compliance discipline rather than ownership of a product asset program
+- the right legal posture is an explicit allowlist and provenance boundary, not pretending the container license resolves the package
+
+## Acceptance markers satisfied
+
+The `0R-C` and `Phase 1R` retained-value markers for this lane are now satisfied in first-party Unreal surfaces:
+
+- a first-party fixture ledger exists for approved, review-required, local-only, and excluded fixture families
+- a first-party allowlist contract exists for bounded fixture, documentation-example, and visual-QA use
+- a first-party provenance and shipping boundary exists for notice, review, and exclusion duties
+- a first-party refresh pattern exists for fixture sync and attribution rechecks
+- bundled first-party reference targets exist for the allowlist, environment-fixture matrix, provenance boundary, refresh pattern, and contributed-geometry smoke-test boundary
+
+## Validation
+
+Validation completed for this packet:
+
+- `git diff --check` passed apart from CRLF conversion warnings
+- JSON validation passed for the updated materialized-catalog files and workspace manifest
+- CSV import validation passed for the four canonical v6.3 ledgers
+- Unreal build succeeded with:
+  - `C:\Program Files\Epic Games\UE_5.7\Engine\Build\BatchFiles\Build.bat UnrealHyperTwistEditor Win64 Development C:\HyperTwist\UnrealHyperTwist\UnrealHyperTwist.uproject -WaitMutex -NoHotReloadFromIDE`
+
+Build result:
+
+- `Succeeded` on `2026-05-13`
+
+## Next move
+
+The next bounded move is `Phase 4R-D`:
+
+- widen `PostHog/posthog` as the retained boundary-sensitive telemetry, replay-diagnostic, and feature-governance lane with `ee/` excluded
+- keep the optional `Phase 3R-G` `pissang/claygl` and `pissang/clay-viewer` comparison lane deferred unless the landed primary browser spatial stack exposes a real gap
