AI DISCLOSURE (as shown in the film)
Architecture generation: GPT-6-Astra (as stated by the lab).
Video generation: Claude-Opus-5.5 (realism pass, camera paths, renders, Pingyao generator, edit, graphics, score code).
Narration: AI-synthesised voice, Microsoft Edge neural voice en-US-AndrewMultilingualNeural via edge-tts, rate -12%, phrase by phrase,
native pitch, no time-stretching. Only the public narration text was sent to the speech service.
Music: original additive pipe-organ score and clock pulse, v5/audio/score.py (seed 20261019). No samples or film-score quotations.

PICTURE
All building footage is rendered from Digital Engine reconstruction models in Blender 5.0.1 Cycles (path tracing), not location footage.
Source scenes are opened read-only and hash-checked before and after every render (v4/cine/shots/*/receipt.json, v5/cine/shots/*/receipt.json).
v4 realism layer (v4/cine/realism.py), applied in memory only: scanned surface detail on researched base colours, rounded-edge shading,
contact grime, thin architectural glass, procedural mown lawn and CC0 plants, horizon treelines, exposure calibrated per shot.
Barcelona Pavilion stones use matched CC0 scans (onyx, Tinos/Alpine green marble, travertine) as stand-ins, not samples of the original stone.

Drawings shown are the reconstruction model's own plan/section; screenshots are of the Digital Engine platform. Impacts and risers: v6/audio/score.py.

BANK OF CHINA TOWER (v6)
Re-rendered from outputs/digbuild-bank-of-china-bracing-20261022 (bracing positions/angles corrected against published drawings and photographs;
see its reports). The base region and hidden structure remain graphic inference, not survey.

BUILDINGS
Edith Farnsworth House · Nakagin Capsule Tower (1972 — 2022) · Bauhaus Dessau · Villa Savoye · Barcelona Pavilion (1929 state)
· Church of the Light (Tadao Ando, 1989) · Yingxian Wooden Pagoda (Liao, 1056) · Notre-Dame du Haut · Fallingwater · Bank of China Tower.
These credits do not relicense the original architectural designs.

YINGXIAN PAGODA — STRUCTURE VISUALIZATION (v5)
Exploded structure and section/growth shots are rendered from the user's editable pagoda model
(outputs/digbuild-yingxian-pagoda-20261020/model/building.blend, 24,005 components; opened read-only) by v5/cine/yx_fx.py.
Storeys lifting apart, bracket sets fanning out, the "printing" growth front and the moving section plane explain the structure;
they are labelled STRUCTURE VISUALIZATION / 构造演示 and do not show a construction sequence, structural analysis or the current condition.

PINGYAO ANCIENT CITY
Base city generated by outputs/digbuild-pingyao-20261020/scripts/pingyao_build.py from its evidence dossier.
City wall, streets, gates and landmark positions: © OpenStreetMap contributors, ODbL 1.0.
Courtyard and shop fabric is generated from documented building types (typology.md), not surveyed building by building;
unsourced dimensions are listed as assumptions in model/build-receipt.json.
v5 Pingyao shots are re-rendered from the refined scene in outputs/digbuild-pingyao-20261020/refine-v1/ (style pass, courtyards, visitors);
its sources, licences and assumptions are documented there (README_CLAUDE_RENDER.md, ARCHITECTURE_REVIEW.md, audit/). Clothing, crowds,
shop names and atmosphere are presentation settings.

RACETRACK — CONCEPT
Procedural circuit (v4/cine/track_concept.py), shown as wireframe and labelled CONCEPT / 概念演示. Not a real circuit.

"YOUR HOME" — COMING SOON
The house is the lab member's own design (祁安村, Jingjiang; 10.10 final version), shown with the owner's consent.
Cards are the owner's own drone photo, plan and sections. Presentation detailing (sills, curtains, furniture, lights, mist)
is a visual setting, not construction documentation. Photo-to-digital-twin is labelled COMING SOON: it is not yet a released feature.

ROBOT VISION
RGB, depth, semantic-label and surface-normal passes of the same Savoye walk, rendered from the model.
Semantic labels come from object/material-name rules (v4/cine/shots_v4.py SEMANTIC), not hand annotation.
