CANONICAL DEFINITION — VERSION 2.0

Programmed Interface Compression: What PIC Is Not

Programmed Interface Compression is the phenomenon in which two parties sharing an engineered, evolving codebook can shrink their messages toward near-nothing because the shared state carries the meaning.

Boundaries

• A macro maps a fixed label to a fixed action.
• Prompt engineering improves one request.
• Retrieval supplies facts.
• Personalization can remain one-sided.
• Private jargon lacks dependable inspection and repair.

PIC concerns a maintained bilateral reference that reduces repeated communication and remains reviewable.
