INTRODUCTION

English translation pending.

CORE DEFINITION

A trap street, also called a paper street, is a nonexistent road or landmark deliberately drawn into a map so that any competitor reproducing it proves the copy. Reference works apply the same logic with fictitious entries. Its evidentiary force depends entirely on the mark being unique and unpublished, since a detail that appears in independent sources cannot distinguish copying from coincidence.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Plant a fingerprint: insert one small harmless error or invented detail that only your version contains - Watch for copying: monitor whether competitors reproduce that exact detail in their own work - Prove provenance: use the uniqueness of the mark to trace leaks and establish ownership

anchor

Anchor fast decisions

The map contains a detail that exists nowhere in the world, so it can only have come from the mapmaker. When a rival map shows the same invented street, the shared error is far more probable under copying than under independent survey, which converts an invisible act into visible evidence. Uniqueness is what makes the inference hold.
