Verified
Direct source evidence for the exact configuration.
Methodology / 1.0
How a fact earns publication
Urobolus separates exact evidence, bounded corroboration, calculations, and unknowns so a clean table never implies false certainty.
- 01
Identify the US configuration
- 02
Collect manufacturer and government records
- 03
Attach a locator to every fact
- 04
Preserve conflicts and publication gaps
- 05
Localize labels without changing market facts
Evidence states
Verified is direct evidence. Corroborated is a bounded cross-source conclusion. Derived is calculated from published inputs. Unverified remains visibly unresolved.
Corroborated
Bounded conclusion from multiple sources or shared North American hardware.
Derived
Reproducible calculation using published inputs and a visible formula.
Unverified
Unpublished or not exact-applicable; never replaced with an estimate.
Unknown is not a specification.
If an exact value is not published for this configuration, Urobolus leaves it unresolved instead of promoting an estimate to a factory fact.
