Programmed Interface Compression: Examples Across Domains

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.

Three examples

1. A recurring spreadsheet formula turns a weekly explanation into one refresh action.
2. A maintained checklist turns a long handoff into a named job.
3. A human and AI use an inspectable vocabulary to omit stable details.

Disconfirming case

If a new operator cannot inspect the reference and the receiver cannot explain or repair the mapping, the brevity is private shorthand, not a portable PIC interface.
