A.6.3.CSC:10 - Rationale

Controlled coarsening is useful because FPF work often needs cheap readable forms. It is risky because those forms often travel farther than their admissible use. The pattern therefore begins with direct source/candidate comparison; it makes retained distinctions, loss, non-use, and return explicit enough for the present task, then opens exact endpoint, source, work, evidence, publication, or assurance relations only when a stronger receiving use needs them.

This pattern is narrower than a general simplification pattern. It applies only when the coarsened rendering remains tied to a source-bearing side and has a declared narrower use and return condition.

Keep exact source episteme X recoverable when using or further coarsening Y. Identify each endpoint by its claim content, EntityOfConcern and effective reference scheme; state publication and representation relations separately when they matter. If admissibility is missing, complete the required source or admissibility repair before resuming the blocked use.
