# Rainbow Raccoon Compiler Logogram Projection
This module formalizes the small claim proven by the current Python receipt:
* a logogram can be type-admissible as a `LogogramProjection`;
* a torn logogram can be projection-admissible after repair/quarantine;
* the same torn logogram is not merge-admissible.
This is intentionally not a proof that the source mathematics is true. It is a
proof that the routing discipline separates type admission, projection
admission, and merge admission.
