Cortex
Durable memory — nested star memory identity, not a second parent.Mark law
The nested star is Cortex memory identity. It is not a second Skyzai parent, not a rail logo, and not Cortex-as-project.
The Skyzai parent seal is a different register. Sub-brand marks are not collected on the Us book — they live on this door.
Clearspace
Keep star nesting clearspace; do not flatten into a single parent seal.
Ink
Memory identity ink; corrections remain visible. Do not use as rail/chrome parent.
Appearance follows Skyzai Night Shift / true-tone policy and substrate #050505. Do not invent a second parent palette.
