CURRENT TWO-GALLERY TEACHING PREVIEW — 11 November 2026

History uses the original Codrops Fan Museum stone hall and effects. The
embedded component review is recorded below and in /museum/environments/provenance.json.
The YBC 7302 observation is an original Atlas diagram from Klaus Wagensonner’s
published CDLI reading. https://cdli.earth/cdli-tablet/740
The Brahmagupta observation shows printed p. 339 of H. T. Colebrooke’s 1817
English translation, a public-domain scan from University of Toronto Libraries
and the Internet Archive. Sources and hashes for both images are recorded in
/history/observation/ATTRIBUTION.txt.

Modern uses Art Gallery by denis_cliofas, CC BY 4.0. The local preview restores
gozdemrl’s eight fan characters, iansed’s selected apartment furnishings and
the six adapted miniature scenes. The uploads are labelled CC BY 4.0.
Kenney visitors and individual Poly Haven props retain their CC0 notices.
The corresponding credits, modifications and source records are at
 /museum/visitors/LICENSE.txt
 /museum/visitors/LICENSE-TV.txt
 /museum/tv-scenes/LICENSE.txt
 /museum/modern-studio/LICENSE.txt
The school build plays the supplied Barenaked Ladies recording.
Recording details and rights status are in /museum/audio/provenance.json.
The programme stills remain excluded from the two-gallery exports.
Redistribution of the retained mixed assets and recording remains under review.

Reviewed 1K glTF 2.0 mesh: 1,090 triangles; no geometry decoder required.
Modification: model textures resized to 512 px; geometry unchanged.
Role: contemporary visitor furniture in the modern teaching installation.
It is not a historical mathematical artifact or a claim about ancient furnishings.

Marble 01 — Rob Tuytel / Poly Haven

License: CC0 1.0 Universal; same license links as above.
Modification: 1K diffuse retained; normal/packed roughness maps resized to 512 px.

License: CC0 1.0 Universal; same license links as above.
Modification: material maps resized to 512 px.
Role: surface material on our original modern teaching table; this is a texture,
not a downloaded table model.

Original work: folded roof and its ribs, court/threshold/recess construction,
stone courses and reveals, photograph mounts, counting table and modern decimal
rod tallies, bronze compass and construction board. These are modern educational
installations. Their mathematics consumes the same versioned kernels as HTML.

YBC 7289 photograph: Yale Babylonian Collection; photo via Wikimedia Commons.
https://commons.wikimedia.org/wiki/File:YBC-7289-OBV-REV.jpg
CC0. The museum uses the photograph on a thin display mount; it does not represent
an invented 3D scan of the tablet. Existing photograph provenance is unchanged.

Optional 3D detail loads from packaged local files; no runtime third-party CDN.

2026-10-25 upstream architecture revision (supersedes original-room descriptions above):
History now uses Codrops Fan Museum building GLBs and baked maps by Andrew Woan,
commit 6d611b560edd79e4c3f3e6d679f516b76d11fdff. Original source MIT notice:
/licenses/upstream/CODROPS-MIT.txt. Embedded third-party material/prop provenance
is still pending; these are local development scenes, not cleared publication assets.
Modern now uses original Museum of Ages procedural architectural geometry,
commit e52c71dfd678a836a0af064d8dcba73da4b93e3d, adapted offline for WebGL.
AGPL source and separate data notices: /licenses/upstream/MUSEUM-OF-AGES-AGPL.txt
and /licenses/upstream/MUSEUM-OF-AGES-CONTENT.md.
Viewer camera-fit, bounded model cache and disposal utilities are directly reused
from s010s/prehistoric-animal-museum, commit dbe71900fc76a31513d675a4743373707395a936.
License: /licenses/upstream/PREHISTORIC-AGPL.txt. No animal models or narration reused.
Per-model source, original path, hashes, modification notes and clearance state:
/museum/environments/provenance.json. Corresponding source and generation scripts
are retained in this local project; a public source offer is required before release.

2026-10-25 restored experience revision (supersedes the preceding Modern description):
Modern runtime: This work is based on "Art Gallery"
https://sketchfab.com/3d-models/art-gallery-3c3248e07296402ead6facab0a09bdcc
by denis_cliofas https://sketchfab.com/denis_cliofas
licensed under CC-BY-4.0 https://creativecommons.org/licenses/by/4.0/
Original building, lights, benches, frame geometry and full PBR material channels
are retained. Runtime textures replace twelve existing painting surfaces with
six mathematical previews and questions. The existing optimized source package
was copied from the read-only BIPH museum redesign project. See the precise
original and delivery hashes in /museum/environments/art-gallery/provenance.json.
Museum of Ages generators/exports are archived locally; they are no longer loaded.

History: original Codrops route, loading reveal, environment shaders, Bird and
Waterfall models restored. Five native Ninth picture regions contain sourced
Atlas content; original frame/border pixels remain. No Epidemic Sound music or
uncleared audio is packaged. Eagle Lake by Astigmatic: SIL Open Font License 1.1;
/museum/environments/codrops/EagleLake-OFL.txt.

Direct upstream source and modifications remain in vendor/, src/lib/upstream/,
src/components/museum/, and scripts/upstream/. MIT/AGPL notices remain bundled.
Specific Codrops embedded-media rights still require completion before public
redistribution; this local implementation does not imply that clearance.

2026-10-26 Mini visitor revision:
Mini Characters 1.0 by Kenney, https://kenney.nl/assets/mini-characters
CC0-1.0: https://creativecommons.org/publicdomain/zero/1.0/
Twelve original GLB characters, animations and their shared colormap are unchanged.
Runtime adapters normalize height and blend existing idle/walk/sprint/jump/fall
clips. Selection previews are locally rendered from these models.
Original license, exact archive/file hashes: /museum/visitors/LICENSE.txt and
/museum/visitors/provenance.json. Reproducible scripts: scripts/avatars/.
Camera boom and collision concepts reuse the read-only BIPH museum redesign
project's gallery-navigation.ts; adapted to the existing R3F camera owner with
near-plane, ceiling and ground checks. No source project was modified.

2026-11-01 Television character and miniature revision:
Characters Chibis by gozdemrl, CC BY 4.0:
https://sketchfab.com/3d-models/the-big-bang-theory-characters-chibis-9c00c38ea677430b970d2a1a970d4d9e

https://sketchfab.com/3d-models/the-big-bang-theory-virtual-apartment-0d8ee60747b34142aa886557c0e3d038
License: https://creativecommons.org/licenses/by/4.0/
Eight characters extracted, given original eleven-joint skins, shared base-colour
atlas, retargeted Kenney CC0 actions and seated corrective shapes. Six approved
Kenney visitors remain unchanged; six retired IDs remain in provenance only.
Selected sofa, round tabletop and bookshelf components are adapted at miniature
scale with sampled vertex colours. Cast static poses, plinths and simplified
teaching props are exhibition adaptations, not official programme assets.
Exact source/file hashes and modification records:
/museum/visitors/tv-provenance.json and /museum/tv-scenes/provenance.json.
Both supplied source GLBs and the reference materials remain unchanged.

Video entries are outbound source links, never locally redistributed video files.

Motion repair (2 November 2026): original walk/run at 2.6/3.4 steps per second, articulated knees and feet, separate locomotion leg corrective. Other actions retain their attributed Kenney adaptation. Scene collision data is generated per solid component before merging; display plinths are nonblocking.
