Single Definition means every defined centre in the chart is connected into one continuous circuit. There is no gap anywhere in the definition.

It is one of the two most common arrangements. Measured across our own stored charts, about 42% are Single Definition and about 46% are Split, so between them they account for the large majority of people.

This entry is part of the reference library Bella reads from when she answers questions about your chart. It was written by us, with the structural facts pinned to our own chart data rather than to a general model's recollection.

Provenance: rewritten 2026-08-20. The previous content was not an entry: the model declined the task and asked for source material, and that reply was saved into the library verbatim and served to members. Strategy, signature and not-self are pinned from our own chart engine; prevalence measured across our own stored charts.
