What flattening actually looks like.

Flattening is rarely loud. It does not announce itself as crisis. It presents as a narrowing — of affect, of interest, of preference, of texture in ordinary experience. The person is still functioning. The range has simply contracted.

Inside HCST, flattening is a protective adaptation. Under sustained load, the system reallocates dimensional bandwidth toward immediate survival management. The contraction is logical. It is also costly.

Common surface signatures

• 01A shortened range of emotional response.
• 02Reduced interest in previously meaningful inputs.
• 03Narrowed time horizon and forward orientation.
• 04Decreased differentiation between options that previously felt distinct.
• 05A subjective sense of being further away from oneself.

Read as character, these signatures are misread. Read as system output, they are diagnostic.
