What ⯐ means
It is a square marker for indicating a position.
The surrounding notation determines which position it identifies. Unicode’s proposal cross-references ⌖ as the position indicator, documenting a relationship between the square and crosshair-like symbols; it does not make them interchangeable.
Technical and context-dependent: it identifies a position, while the surrounding notation supplies the details.
⌖ is related, but it is a different glyph with a crosshair center.
