Selection / Marking / Engineering
The Deep-Time Somatic-Control Typology — Report #105
SELECTION — alters who survives to reproduce and who mixes into the pool (sacrifice, infanticide, endogamy).
MARKING — indelible visible alteration enforcing caste/covenant without changing physiology (circumcision, scarification, religious tattooing); a social password.
ENGINEERING — fundamentally modifies morphology/decay to transcend limits or enforce class (cranial deformation, foot-binding, castration, mummification).
Adversarial floor: restorative trepanation and mundane therapeutic tattooing FAIL the threshold — somatic maintenance, no selection/gatekeeping function.
