Evidence first. Interpretation made visible.
NaijaOS separates what was measured, what was reported, what was observed, what was estimated and what was inferred.
Source hierarchy
We begin with official releases and primary records. Reputable reporting supplies events and context. Market observations are identified by place and observation date. Company information is verified with the participating business before it shapes a personalised brief.
Observation date and geography
A current signal must state when and where its underlying conditions were observed. A national average is not presented as a local route condition; an Abuja–Lafia observation is not silently extended to Nigeria.
Data, estimate and inference
Transmission analysis
We ask what changed, what caused it, what it may affect next, the likely lag and which part of a business is exposed. Transmission is a reasoned assessment—not certainty about the future.
Confidence levels
High means strong, current and converging evidence. Moderate means useful evidence with material verification still required. Low means an early or incomplete signal that should be treated primarily as a question for investigation.
Company verification and limitations
Public conditions do not reveal a company’s actual supplier quotation, route cost, inventory position, credit exposure or margin. These must be verified by the business. NaijaOS does not replace accounting, legal, tax, financial or investment advice.
Corrections
If a figure is stale, a source has changed or an interpretation is wrong, email info@naijaos.io. Corrections are part of the operating standard.
