Spw Operator
& Merge
The runtime type is subject. Merge is the public alias. & names the bound focus of a relation. It overlays fields without pretending they were always one thing.
Contract
Interaction
Overlay, compare, or combine fields. A merge should preserve source identity enough that the integration remains inspectable.
Metaphysics
Merge is superposition: two fields occupy the same reading surface long enough to form a third relation.
Brace Physics
A merge brace carries paired charge. It should show both incoming vectors rather than hiding conflict under a smooth result.
Symmetry
Prefix &x primes a unit for integration. Postfix x& marks that the unit remains mergeable after reading.
