Spw Operator
$ Meta
The meta operator reflects on the medium itself. It asks the surface to show its trace, register, or conditions of interpretation.
Contract
Interaction
Inspect the medium, trace, or register itself. Meta should reveal how a surface is behaving, not merely add commentary.
Metaphysics
Meta is metacognition: attention notices the instrument it is using to notice.
Brace Physics
A meta brace folds the boundary back onto itself. Its charge should become inspectability rather than hidden mystique.
Symmetry
Prefix $x primes reflection on the next unit. Postfix x$ marks that the unit leaves a reflective trace.
