Topic Hierarchy Design#
Merged into
topic-hierarchy.md, which is the single, API-accurate reference for the topic namespace, wildcard semantics, and access levels. This file previously duplicated that content (with drift); its unique material β the wildcard matcher truth-table behavior and thepattern_truth_tablesnapshot test reference β now lives intopic-hierarchy.mdunder "Wildcard Support".
See topic-hierarchy.md.
