Structural Centre Question

Where is the centre?

The laboratory does not answer until the structural question is declared. A coordinate is only one possible outcome. The same framework can also preserve multiple centres, expose ambiguity, or refuse resolution when required structure is missing.

Before resolving a centre

Centre of what carrier?

Using what measure or weighting?

Using what metric or objective?

Is one unique centre structurally justified?

Are all required dependencies present and compatible?

Exact Centre

A unique exact centroid from a declared finite carrier.

Resolution state

RESOLVED_POINT

Centre result

[1, 1]

Structural question

Exact weighted centroid with equal weights

Evidence identity

Bounded Earth-Specific Layer

The same word "centre" can ask structurally different Earth questions.

Choose any bounded case below. The laboratory resolves only within the declared carrier, profile, dependencies, and claim authority. A model origin, a reference-system origin, a live physical geocentre, a surface representative, and a dataset-dependent centre are not silently collapsed into one claim.

Evidence-Bound Real Land Centre

Spherical Land-Area Vector Centre Direction

This result is bound to the exact embedded dataset identity and the declared real-land computation profile. It is not presented as a universal geographical centre of Earth.

Resolve more than a coordinate

Structural Centre Differential identifies declared dependency changes. Centre Stability Envelope can return a bounded RESOLVED_REGION. Symmetry Certificate records why uniqueness is admitted or refused. Centre Resolution Certificate binds claim identity, result material, witnesses, and evidence.

claim structure + admitted dependencies + bounded result + witnesses -> resolution certificate
