Semantic Geometry over Cog
A fixed-fixture comparison asks whether semantic geometry earns a separate language or works better as explicit schemas and helpers over Cog.
Presents the frozen Selection Algebra and all nine MCC-COG-COMP-001 observations. Modest declaration savings, unchanged native trace limitations, and a blocked stage extension support retaining Cog for the tested fixture.
The comparison used one fixed fixture and reused existing implementations with a known construction order.
