 The memory:// URL scheme provides a unified way to address knowledge across projects:
 memory://project-name/path/to/content
 
-The host portion (project-name) identifies the knowledge base context, while
-the path represents a relative permalink within that project.
-
 Examples:
-    memory://basic-memory/specs/search/*           # Pattern matching
-    memory://basic-memory/topic/search~ranking     # Fuzzy search
-    memory://basic-memory/specs/link-resolution    # Exact permalink
-    memory://basic-memory/related/sync             # Related content
-    memory://basic-memory/context/current          # Context building
+    memory://basic-memory/specs/search/*      # Pattern matching
+    memory://basic-memory/specs/xyz           # Exact permalink
+    memory://basic-memory/related/sync        # Related content
