Diagram: From Bits to Meaning

Conceptual Path

"context can change interpretation" .-> G E -. "same pattern can serve different roles" .-> G

Reading The Diagram

The left side is about choosing distinctions and assigning codes. The middle is about representing those distinctions as bits and grouped bit patterns. The right side is about interpretation: a pattern matters because some layer treats it according to a contract.

Inference across sources: meaning is not located at a single point. It emerges from the path plus the interpreter. The same stored pattern can be meaningful in different ways when a different interpreter is applied.
