Six authorities
Is the geometry to real scale?
Surveyed, scanned, or CAD-derived geometry can hold it. Eyeballed blockouts and text-prompt outputs do not.
Does the virtual camera behave like the real one?
Focal length, sensor, focus, filters, and kinematics must be real where a camera-dependent decision is at stake.
Will the light behave as shown?
Fixture definitions, geometry, sun position, date, time, and glazing matter. A photoreal image can still be wrong.
Does matter behave?
Loads, collisions, flow, thermal behaviour, and clearance require a simulation or measurement, not only an animation.
Where did every asset come from?
Authored, scanned, licensed, or generated, with terms and dates attached. Previs assets can migrate downstream.
Can someone reproduce it later?
Version history, open formats, source files, and a record of what changed are part of the artifact at higher classes.
Class requirements
| Class | Use | Minimum authority |
|---|---|---|
| 0–2 | Inspiration, alignment, creative approval | Visual intent; provenance advised |
| 3 | Commercial pitch or sale | Provenance required |
| 4 | Planning budget, schedule, quantities | Dimensional plus provenance |
| 5 | Technical execution | Dimensional, optical, photometric, physical, provenance |
| 6 | Regulated artifact | All six, fully auditable |
Find the highest class anyone will use the artifact for. If the required authority is absent, acquire it or downgrade the claim.
Synthesized from the supplied Risk and Accuracy Framework and Worked Examples. The research itself marks this framework as an internal draft pending practitioner review.
